About this talk:
The humpback whale (Megaptera novaeangliae) is a species known for its singing 
abilities. Humpback whale song is a complex system built in a methodical way: 
units, the smallest elements – similar to notes – combine to form phrases, 
repeated phrases constitute a theme, and different themes make up a song. Each 
population of humpback whales has a specific song, which is predominantly 
expressed on the breeding ground.
These songs change throughout the year. When the change is subtle, it is called 
song “evolution”. Sometimes, however, songs go through sudden and intense 
changes, recognized as song “revolutions”. These abrupt changes have so far 
only been recorded in humpback whale populations in Australia and surrounding 
areas.
Our understanding of how, why, and how much difference there is between song 
“evolution” and “revolution” is still growing. However, using passive acoustic 
monitoring, we identified abrupt changes in humpback whale song in the 
Southwest Atlantic, off the Brazilian coast. We suggest this is the newest case 
of song revolution and the first recorded outside of the Pacific. Our findings 
also indicate these kinds of abrupt changes may only occur in Southern 
hemisphere humpback whale populations, and in this talk we propose several 
reasons for this difference from Northern hemisphere whales.

About the presenters:
Divna Djokic is a biologist originally from Serbia. As Serbia has no sea, she 
headed to the coasts to learn to speak whale. She completed a Masters in Marine 
Ecology in the lab of Dr. Michel Andre, focused on the acoustic ecology of 
sperm whales and worked as a Marine Mammal Observer in Italy before heading to 
Brazil, where she completed a PhD in humpback whale acoustics under the 
supervision of Dr. Renata Sousa Lima. The paper she will present with her 
colleague Isabel is a part of her PhD thesis research.
Maria Isabel Gonçalves is a Portuguese marine biologist who lives in Brazil and 
coordinates the Whales from the Hill Project. She received her PhD in Ecology 
and Biodiversity Conservation from the State University of Santa Cruz, Brazil, 
which was the starting point of the Whales from the Hill Project, a research 
and conservation effort that studies humpback whales in southern Bahia. Her 
interests include the ecology, behavior, and communication of cetaceans and 
communicating science to the broader public.

Greetings MARMAM community!

Join us on Thursday April 18th 2024 at 04 pm PDT / 7 pm EDT / 7 am AWST (+1)

Cost of migration and migratory timing in Western Australian humpback whales
with Grace Russell

The talk will also be live streamed on the SMM Facebook page.

About this talk:
Migratory humpback whales cover the cost of reproduction in low-latitude
breeding grounds with stored energy accumulated from polar feeding grounds.
The ability to accumulate sufficient energy reserves during feeding periods
is vital for key life history stages during migration, including mating,
calving, and lactation. This study aimed to investigate the relationship
between migration timing and body condition of Western Australian humpback
whales. We used drone footage to measure body condition by obtaining
morphometric measurements from 460 individuals. The body condition of
juveniles was shown to be correlated with migration timing for their
northern migration, with individuals in better body condition migrating to
the breeding grounds earlier. While stored energy is vital for humpback
whales to successfully complete their vast migration to-and-from breeding
grounds, we found no evidence that body condition affects the migration
timing for adults, lactating females, and calves.

About the presenter:
Grace has recently completed her PhD at Southern Cross University in the
Northern Rivers of New South Wales. For the past four years she has studied
the body condition of the two breeding populations of humpback whales in
Australia (east and west coast) and the South-east Indian Ocean population
of pygmy blue whales, exploring the relationship between migration timing
and body condition, as well as energetic usage over their migration. During
her PhD Grace created The Fat Whales Project and now her research focuses
on the energetics, physiology and morphology of cetacean species in
Australia. Grace is an experienced remote pilot (using drones) and has
worked on marine mammal research projects in Bremer Bay (orca), Ningaloo
Reef (blue whales), and the Great Barrier Reef (dolphins).

[MARMAM] Upcoming SMM Editors Select Webinar, 21 March 2024: A first investigation of geographical variation in Cape fur seals’ in-air vocalizations, with Dr. Mathilde Martin

Greetings MARMAM community!

Join us on Thursday March 21st 2024 at 10 am EDT / 2 pm GMT / 3 pm CET for the 
next SMM Editors Select Series Webinar:
A first investigation of geographical variation in Cape fur seals’ in-air 
vocalizations, with Dr. Mathilde Martin

This event is free to attend and presented online via Zoom, but registration is 
required.
Register here:

Space on Zoom is limited to the first 500 attendees. The talk will also be 
streamed live on the SMM Facebook page 
.

About this talk:
Marine mammals are known to communicate extensively through acoustic signals in 
all their social interactions. In pinnipeds (seals, fur seals, and walruses), 
breeding takes place on land (or on ice) and individuals use in-air 
vocalisations to exchange information between mating partners or between mother 
and young. Cape fur seals breed at about 40 different breeding sites 
distributed along the southwest and south coasts of Southern Africa. These 
colonies are located on both the mainland and islands and are characterized by 
various terrains such as bare rock, boulders, ledges, or open sandy beaches. In 
this study, we compared the acoustic features of Cape fur seals’ vocalisations 
recorded at 6 different study sites in Namibia and South Africa to investigate 
potential geographical variation in the species’ vocal repertoire. Comparisons 
among closely located sites revealed limited geographical variation whereas 
more pronounced differences were found in the frequency structure of males, 
females and pups’ vocalisations recorded at more distant sites. Although we 
were unable to control for certain factors (mainly due to the difficulty of 
accessing the colonies), we discuss here the potential impact of social and 
environmental factors in driving intra-species variation in Cape fur seals’ 
vocalisations. Such investigations help understand how acoustic communication 
in marine mammals is shaped by ecological drivers.

About the presenter:
Mathilde Martin is a biologist, specialist in animal behaviour, and more 
specifically in acoustic communication in terrestrial and marine mammals. Her 
research focuses on deciphering what information is encoded in their 
vocalisations and how vocal signals can modulate socials interactions, in 
relation to the species’ ecological constraints. Her approach combines audio 
recordings in the field, analyses of the acoustic structure of vocalisations 
and experimental tests on wild animals. Mathilde first explored the social 
calls exchanged during mother-calf interactions in humpback whales. Then, 
during her PhD at the Institute of Neurosciences Paris-Saclay, she investigated 
several aspects of the acoustic communication network of the Cape fur seal, 
such as the transmission of individual information, male-male or mother-pup 
individual vocal recognition systems, as well as the impact of noise pollution 
on the behaviour of these animals. She is now a postdoctoral researcher at the 
University of Zurich where she is studying the role of meerkats’ close calls in 
the maintenance of group cohesion during foraging.

the next SMM Editors Select Series Webinar:
Foraging migration ontogeny in southern elephant seals: finding their way as 
they go? with Dr. Trevor McIntyre

This event is free to attend and presented online via Zoom, but registration is 
required.
Register here: 
https://us06web.zoom.us/webinar/register/WN_l7Hva63SRea5GJgW-BOlkQ#/registration
Space on Zoom is limited to the first 500 attendees. The talk will also be 
streamed live on the SMM Facebook page.

About this talk:
Elephant seal pups are abandoned by their mothers when they are between three 
and four weeks of age. After a short period of fasting on-land, they depart on 
their first foraging migrations unaccompanied by adults. These maiden foraging 
trips normally last longer than three months, during which they must avoid 
potential predators such as orcas and find sufficient food in the vast Southern 
Ocean. The development of the skills needed to successfully navigate these 
early foraging trips is poorly understood, not only in elephant seals, but in 
many animals that perform extreme migratory behaviours. We studied the maiden 
foraging trips of recently weaned southern elephant seal pups from Marion 
Island ̶ a small, but intensively studied population located in the southern 
Indian Ocean. Unlike the adults of this population, recently weaned pups did 
not show evidence of consistency in travel directions, distances and speed of 
travel between individuals, or even between sequential foraging trips by the 
same individuals. Cumulatively, our results suggest that the foraging 
strategies of adult elephant seals from this population are strongly influenced 
by rapid learning while at-sea and is likely less reliant on innate behaviours 
or innate responses to large-scale environmental cues. There remains a need for 
continued longitudinal studies to better understand what the likely 
population-level effects of juvenile behavioural strategies are.

About the presenter:
Dr Trevor McIntyre is an Associate Professor in Zoology at the University of 
South Africa (UNISA). He first started working with marine mammals as a field 
assistant on the Marion Island Marine Mammal Programme in 2005, before 
continuing with his PhD studies on at-sea behaviours of southern elephant seals 
at the University of Pretoria. Dr McIntyre then commenced  a few years of 
postdoctoral research in South Africa and at the Alfred Wegener Institute in 
Germany, followed by a lecturing position at the University of KwaZulu-Natal, 
before joining UNISA in 2019. His broad research interests are centred around 
behavioural adaptations of animals to environmental change, particularly for 
semi-aquatic mammals such as seals and otters. Current research projects he is 
involved in include studies on the ecology of African clawless otter in 
freshwater systems of South Africa and Ross seals in the eastern Weddell Sea, 
Antarctica.

Space on Zoom is limited to the first 500 attendees. The talk will also be 
streamed live on the SMM Facebook page.

About the talk:
Understanding how a species’ metabolic rate varies in different behavioral 
contexts is useful for quantifying prey requirements and foraging efficiencies 
of individuals. Field metabolic rates (FMR) are daily estimates of oxygen 
consumption, which depend on three factors: lung capacity, breathing rate, and 
the amount of oxygen extracted from the air. This study describes a novel 
approach to estimating tidal lung volumes (VT) of actively foraging adult gray 
whales and compares those to VT estimates of gray whales studied in a winter 
breeding/calving lagoon. An unoccupied aircraft system (UAS) along the central 
Oregon coast monitored foraging whales from 2016-2020. Breathing patterns of 
gray whales typically include very rapid exhalation/inhalation events as they 
surface, followed by submerged breath holds of varying duration and depth. UAS 
video and acoustic recordings revealed that foraging whales have 35-40% higher 
mass-relative VT values than resting lagoon females. This reflects differences 
in behavior, activity levels, and oxygen needs between the two groups.
The tidal lung volumes of fasting lagoon whales and foraging whales fall 
between that of resting terrestrial mammals and small to medium-sized 
odontocetes. The methods described here, especially the use of UASs for 
measuring body lengths and breathing rates, provide a new tool for estimating 
gray whale oxygen consumption and energy requirements.

About the presenter:
Dr. Renee Albertson is a teaching professor and research affiliate at Oregon 
State University, where her current research focuses on gray whale physiology. 
In collaboration with multiple scientists within the university’s Marine Mammal 
Institute, she has been studying gray whale metabolic rates and aerobic dive 
limits, including the research she will share today. Dr. Albertson earned BS 
degrees in Chemistry and Biochemistry and a MA in Teaching from Pacific 
University in 1994 and 1997, and taught high school chemistry from 1997 to 
2007. She began her career in marine mammal science in 2005, when she completed 
an intensive internship in Moorea, French Polynesia working on 
photo-identification of small cetaceans and humpback whales. She went on to 
complete her MSc and PhD degrees at Oregon State University with Dr. Scott 
Baker, where she used genetic markers and photo identification to study 
migratory patterns and abundance of South Pacific humpback whales and 
phylogeographic patterns and taxonomic and social structures of rough-toothed 
dolphins. After completing her PhD in 2014 she worked as a postdoctoral scholar 
for Dr. Ari Friedlaender, where she evaluated changes in humpback whale 
migration and fine-scale population structure in the Western Antarctic 
Peninsula, one of the fastest warming areas on the planet. Today, in addition 
to her research, she teaches several field-based marine mammal courses at 
Oregon State University and continues to collaborate with scientists and policy 
makers in the South Pacific.

Space on Zoom is limited to the first 500 attendees. The talk will also be 
streamed live on the SMM Facebook page.

About the talk:
Concerns were raised about possible behavioural disturbance to narwhals 
(Monodon monoceros) when exposed to shipping noise in Milne Inlet, Baffin 
Island, Nunavut, Canada. It is known that marine mammals often change their 
behaviours especially their vocalizations, around ships.  With the use of 
underwater recordings operating continuously over two months (in 2018 and 
2019), narwhal vocalizations in Milne Inlet were analyzed. Narwhals produce 
three social call types, whistles, buzzes and knocks. The calling rates of each 
call type were determined when no ships were present and during ship transits 
in a before-during-after analysis. Narwhal call counts were generally lower 
when bulk carriers were within line-of-sight (5 km), including when ship noise 
levels were barely above background noise levels. Call counts varied both 
“before” and “after” individual bulk carriers passed by the recorders. There 
was no evidence of habituation or sensitization to the bulk carrier noise 
within or between years. Continued monitoring in this area is recommended, 
especially if shipping levels increase.

About the presenter:
Crystal studied at the University of New Brunswick, in Saint John, NB, Canada 
for undergraduate and graduate studies. Her honours project was on the 
underwater soundscape of Mawson Station, Antarctica and the impacts this could 
have on the masking of Weddell seal calls.  Her masters thesis was on the 
classification of narwhal calls and the changes in calling rates in association 
with passing ships. She has also volunteered with various organizations (Bimini 
Biological Field Station, Dolphin Communication Project and Operation Wallacea) 
for marine mammal, fish and marine invertebrate studies.

Space on Zoom is limited to the first 500 attendees. The talk will also be
streamed live on the SMM Facebook page.

About the talk:
Despite the lack of obvious physical barriers and their ability to travel
significant distances, many marine mammals exhibit substantial population
structuring over relatively short geographical distances. The dugong (*Dugong
dugon*) is a vulnerable marine mammal found in inshore seagrass habitats
throughout the Indo-Pacific, including in the waters of northern Australia.
We investigated the genetic population structure of dugongs in the shallow
coastal waters along >2000 km of the eastern Queensland coast including the
Great Barrier Reef region. Microsatellite genotypes for 22 loci in 293
dugongs, SNP genotypes based on 10,690 loci in 43 dugongs, and 410 bp
mitochondrial control-region sequences from 639 dugongs were analysed.
Clustering analysis techniques consistently identified an abrupt genetic
break in the Whitsunday Islands region of central Queensland (20.3°S),
which interrupts an overall pattern of isolation-by-distance. Geographic
distance was relatively more important than sea-surface temperature and
seagrass distribution in explaining pairwise microsatellite genetic
distances. The cause of reduced dispersal across this region is unknown but
might relate to an unusual tidal and current mix, termed the ‘sticky-water’
effect, and/or a break in the geographical distribution of offshore
seagrass meadows. This genetic structuring suggests distinct breeding units
north and south of the Whitsunday Islands region, and also mostly separate
populations with limited gene flow within each of the north and south
ranges. Recently, profiles of faecal microbiota from dugongs from all along
the Queensland coast show marked variation, supporting these separate
populations and possibly indicating ecological differences, e.g., feeding
niches. Implications of these separate genetic populations in terms of how
dugongs might respond to local threats to habitat and how these findings
should be considered when developing management plans for Queensland
dugongs will be discussed.

About the presenter:
Janet Lanyon is a zoologist, specializing in marine mammal biology. For
thirty years, Janet has been a full-time academic at The University of
Queensland (UQ) and Director of the UQ Marine Vertebrate Research Group.
Since 1995, she has been Lead Investigator in a long-term population and
health study of the dugongs of southern Queensland, Australia. She has
published widely on diverse aspects of the biology of marine wildlife, and

Greetings MARMAM community!

Join us on Thursday, 21 September 2023 at 1 pm EDT / 6 pm GMT / 7 pm CET for 
the next SMM Editors' Select Series Webinar: Using drones to investigate the 
timing of harbour seal pupping, with Dr. Anders Galatius

Space on Zoom is limited to the first 500 attendees. The talk will also be 
streamed live on the SMM Facebook page.

About the talk:
Harbour seal females give birth to their single pup during a distinct pupping 
season, which occurs during the summer in most areas. To obtain unbiased 
estimates of the pup production of harbour seals, surveys of seal colonies need 
to be timed optimally and conducted under sufficiently similar conditions. In 
the Limfjord, the resident harbour seal population have about 95% of their pups 
at two haul-outs, Ejerslev Røn and Blinderøn just 3 km apart. The short 
distance makes this area ideal for investigation with drones. We counted 
harbour seal pups at these two haul-outs throughout the pupping season in June 
for three consecutive years, 2017-2019. As harbour seal pups can swim almost 
from birth, there was considerable variation in the counts. Some of this 
variation could be related to date; as the season progressed, increasing 
numbers of pups were hauled out, before the counts began to drop, with an 
estimated peak in counts on June 22nd. Weather also impacted the counts, on 
windy days, fewer pups were counted. These findings will be used in the 
planning and interpretation of harbour seal pup surveys in Denmark.

About the presenter:
Anders Galatius is a senior researcher at Aarhus University’s Department of 
Ecoscience where he works on marine mammal morphology, ecology and behaviour. 
He graduated as MSc from University of Copenhagen, Denmark in 2003 and obtained 
his PhD from the same university in 2009. He has been working at Aarhus 
University since 2010, leading the Danish seal monitoring programmes of harbour 
seals and grey seals since 2013.

[MARMAM] Requested post: SMM Editors' Select Series Webinar, 17 August 2023

2023-08-10 Thread Student Members-at-Large Society for Marine Mammalogy
Greetings MARMAM!

Join us on 17 August 2023 at 7 am PDT / 10 am EDT / 2 pm GMT for the next SMM 
Editors’ Select Series Webinar: How to weigh a sperm whale using drone images? 
with Maria Glarou

This event is free to attend and presented online via Zoom, but registration is 
required. 
Register here: 
https://us06web.zoom.us/webinar/register/WN_DY270A_iTF6pBeoUavFcCQ 
 
Space on Zoom is limited to the first 500 attendees. The talk will also be 
streamed live on the SMM Facebook page.

About this talk:
Body mass is a fundamental characteristic of animals. Although sperm whales 
(Physeter macrocephalus) are the largest toothed predators on earth, body mass 
is seldom included in studies of their ecology and physiology due to the 
inherent difficulties of obtaining direct measurements. We used drone images to 
estimate the weight of free-ranging sperm whales. We collected aerial images of 
102 sperm whales (of all reproductive classes) in the Eastern Caribbean and 
Mediterranean Sea during 2017–2020. First, we obtained body length, width, and 
height (at 5% increments) measurements from dorsal and lateral drone images. 
Based on these measurements, we then created an elliptical 3D body shape model 
to calculate the body volume of the animals. We used 4 different approaches to 
convert volume to mass: tissue-density estimates from catch data, animal-borne 
tags, and body-tissue composition. Our results showed that the average total 
body density ranged from 834 to 1,003 kg/m3, while the weight predictions 
matched with existing measurements and weight-length relationships described in 
previous research. Our body-mass models can be used to study sperm whale 
bioenergetics, including inter- and intra-seasonal variations in body 
condition, somatic growth, metabolic rates, and cost of reproduction.

About the presenter:
Maria Glarou is originally from Greece. She holds a BSc degree in Biology from 
the University of Patras (Greece), and is a MSc graduate from Stockholm 
University (Sweden) with a degree in Marine Biology. Her main research 
interests revolve around cetacean bioenergetics, ecology and ecophysiology, as 
well as the impacts of human disturbance on cetaceans. For her MSc project, she 
conducted a pilot study in the Eastern Mediterranean Sea, exploring small-scale 
fisheries interactions with small marine mammals. She is currently a PhD fellow 
at the University of Iceland’s Research Center in Húsavík, where she studies 
the allometry of physiological and behavioural thermoregulatory adaptations of 
different-sized cetaceans in Skjálfandi Bay, NE-Iceland.

About this talk:
In the Bahamas live two communities of spotted dolphins separated by deep
water: one on Little Bahama Bank (LBB) off of Grand Bahama Island and one
on Great Bahama Bank (GBB) off of Bimini. In 2013 an unprecedented 50% of
the LBB spotted dolphins moved across the deep water and took up residence
on GBB. This type of large-scale immigration is rare. How does such a large
group of dolphins move into an established community? This is the story of
how these two communities have reacted, how they have integrated and how
this is shaping the social structure of this new community.

About the presenter:
Dr. Cindy R. Elliser is the Research Director and Founder of Pacific Mammal
Research (PacMam) and Associate Director of the Salish Sea Institute at
Western Washington University. She received her B.S. (2000) and M.S. (2003)
in Biological Sciences from Florida Atlantic University (FAU) and received
her Ph.D. in Integrative Biology from FAU in 2010. Her work focuses on
photo-identification, behavioral ecology and social structure of marine
mammals. For 10 years she worked with Dr. Denise Herzing and the Wild
Dolphin Project studying Atlantic spotted and bottlenose dolphins in the
Bahamas. In 2014 Dr. Elliser moved to the Pacific Northwest and founded
PacMam to study marine mammals in the Salish Sea, particularly harbor
porpoises and harbor seals. Dr. Elliser also teaches biology and related
courses as an associate professor at Skagit Valley College and Western
Washington University.

[MARMAM] SMM Editors' Select Series on February 16th: Are dolphins more affected by commercial fisheries than artisanal fisheries?: A case study from Montenegro

2023-02-08 Thread Student Members-at-Large Society for Marine Mammalogy
Greetings MARMAM!

Join us on Thursday, 16 February 2023 at 4 PM GMT / 8 AM PST / 11 AM EST
for the next SMM Editors’ Select Series: Are dolphins more affected by
commercial fisheries than artisanal fisheries?: A case study from
Montenegro with Mr. Tim Awbery of the Scottish Association for Marine
Science and DMAD - Marine Mammals Research Association.

This event is free to attend and presented online via Zoom, but
registration is required.
Register here:
https://us06web.zoom.us/webinar/register/WN_wIJwObUlS4WwS7lv5g2utA
Space on Zoom is limited to the first 500 attendees. The talk will also be
streamed live on the SMM Facebook page.

About this talk:
Given that bottlenose dolphins are often encountered in coastal waters and
that they have a diet that mainly consists of fish, it is unsurprising that
their habitats often overlap with fisheries. A number of previous studies
have demonstrated that the presence of boats (particularly those associated
with whale-watching) affect marine mammal behaviours, but to the best of
our knowledge, nobody has previously addressed whether different types of
fishing vessels altered the behaviour of marine mammals. In this study, a
combination of land-based and boat-based surveys were used to look at four
different bottlenose dolphin behaviours (diving, socialising,
surface-feeding, and travelling). Dolphins were observed in both the
presence of large, commercial vessels and smaller, artisanal fisheries as
well as in the absence of any marine vessel traffic. Both commercial
fishing vessels and artisanal vessels were found to affect the behaviour of
dolphins, but importantly they affected dolphin behaviour in different
ways. Commercial fishing boats significantly altered the proportion of time
that bottlenose dolphins spent performing three out of four of the recorded
behaviours. Whilst artisanal fishing boats only affected the proportion of
time spent performing one behaviour, this behaviour was surface-feeding, a
behaviour important to dolphins for obvious reasons. If these dolphin
behaviours are interrupted for a long period then it is likely to have
consequences on the health of the dolphin population. This work alongside
previous studies demonstrates that the type of vessel is an important
factor in how a dolphin might be disturbed and therefore must be taken into
account when considering management strategies.

About the presenter:
Tim Awbery is a researcher based in the Marine Mammal Research Team at the
Scottish Association for Marine Science currently investigating minke
whales on the west coast of Scotland. Prior to this, Tim worked in the
Mediterranean for DMAD - Marine Mammals Research Association, an NGO based
in Turkey. Whilst his work took him throughout the north-east
Mediterranean, he was predominantly based in Montenegro, Turkey and Albania
working on a number of marine mammal research projects. Tim has been
involved in the publication of a range of studies that have provided some
of the first data for overlooked regions of these countries. His research
has two primary focuses, 1) building a baseline of marine mammal data in
understudied areas, 2) using this data to understand where marine mammals
and human threats overlap and how these threats may affect marine mammals.
He hopes his work can be used to help inform conservation decisions by
providing concrete information rather than managers being reliant on
anecdotal evidence.

[MARMAM] SMM Editors' Select Series on January 19th: Investigating how humpback whales work together while bubble-net feeding with Ms. Natalie Mastick

2023-01-10 Thread Student Members-at-Large Society for Marine Mammalogy
Greetings MARMAM!

Join us on Thursday, 19 January 2023 at 3 PM PST / 6 PM EST / 11 PM GMT for
the next SMM Editors’ Select Series: Investigating how humpback whales work
together while bubble-net feeding with Ms. Natalie Mastick of the
University of Washington.

This event is free to attend and presented online via Zoom, but
registration is required.
Register here:
https://us06web.zoom.us/webinar/register/WN_kNoCxVnBTFmrXO0uO_nBAg
Space on Zoom is limited to the first 500 attendees. The talk will also be
streamed live on the SMM Facebook page.


About this talk:
In this study, Natalie and her co-authors tagged 26 bubble-net feeding
whales and assessed differences in dive patterns between groups of various
sizes. They found that whales participating in bubble-net dives adopted one
of six dive strategies. More complicated dives were usually used in small
groups. One dive type, the upward spiral, was malleable (it could have
different numbers of rotations,) and was used across all group sizes. The
authors also looked at whether the dive strategies changed based on the
number of whales in the group. There were no differences in the strategies
based on group size except when whales used an upward spiral strategy. The
upward spiral technique changed based on how many whales were feeding
together, suggesting that whales needed to maneuver less, and potentially
work less, to effectively herd the prey to the surface. This finding shows
that working together may benefit the whales by decreasing the amount of
energy they expend to feed.


About the presenter:
Natalie is a marine ecologist with a research focus on marine mammal
behavior, foraging ecology, and parasite ecology. She is a PhD Candidate in
the Wood Lab in the School of Aquatic and Fishery Sciences at the
University of Washington, and a Graduate Research Fellow with Oceans
Initiative. For her PhD, she is studying the change in risk of parasite
infections in marine mammals. Natalie is also a founding member and
Research Associate with Sound Science Research Collective, where she
researches humpback whale behavior in Southeast Alaska. Natalie received
her B.S. in Marine Biology and B.A. in Environmental Studies at the
University of California, Santa Cruz, and her M.Sc. in Wildlife Science at
Oregon State University.

[MARMAM] SMM Editors' Select Series on December 15th: Hormones and whales: what tiny molecules can tell us about the giants of the sea

2022-12-12 Thread Student Members-at-Large Society for Marine Mammalogy
Greetings MARMAM!

Join us on *Thursday, December 15th 3 PM AKST / 4 PM PST / 7 PM EST
(December 16th 12 AM GMT)* for the next SMM Editors’ Select Series:
Hormones and whales: what tiny molecules can tell us about the giants of
the sea with Dr. Valentina Melica of Fisheries and Oceans Canada.

This event is free to attend and presented online via Zoom, but
registration is required.
Register here:
https://us06web.zoom.us/webinar/register/WN_bZI5tOxLSNy_s8xXOt1TUQ
Space on Zoom is limited to the first 500 attendees. The talk will also be
streamed live on the SMM Facebook page.

*About this talk:*
Hormones are tiny molecules that regulate many functions in our (and in a
whale) body. Some of them have the important job to keep the energy level
up in challenging situations. We researched how these hormones behave in
response to ordinary changes in the life of blue and gray whales. We found
that soon-to-be mothers blue whales and nursing gray whales experienced
higher energy demands, thus their hormones were elevated. This information
is essential for understanding how whales may cope with stressors caused by
human activities.

*About the presenter:*
Dr. Valentina Melica is a research biologist specializing in endocrine
analysis. She grew up in Italy, where she worked as an aquarist and snorkel
guide in northeast Italy and earned a master's degree from the University
of Trieste, with a research project on moon jellyfish. She completed her
PhD at the University of Alaska Fairbanks, where her research focused on
reproductive and stress-related endocrinology in the eastern North Pacific
populations of blue and gray whales. She now lives in North Vancouver,
Canada, where she is research scientist with the Department of Fisheries
and Oceans, in the Marine Mammal Conservation Physiology program. In that
position, she is studying biomarkers in killer whales and humpback whales.

[MARMAM] SMM Editors' Select Series on November 17th: Life in the fast lane: differences in behavior between lactating and non-lactating Antarctic fur seals at high latitudes

2022-11-08 Thread Student Members-at-Large Society for Marine Mammalogy
Greetings MARMAM!

Join us on* Thursday, 17 November 2022 at 6 PM GMT / 1 PM EST / 10 AM PST *for
the next SMM Seminar Editors' Select Series: Life in the fast lane:
differences in behavior between lactating and non-lactating Antarctic fur
seals at high latitudes with Dr. Renato Borras-Chavez.

This event is free to attend and presented online via Zoom, but

Space on Zoom is limited to the first 500 attendees. The talk will also be
streamed live on the SMM Facebook page.

*About this talk:*
Mammals spend more energy when lactating (i.e., feeding their young) than
at any other time in their lives. Antarctic fur seal mothers perform trips
to sea to find food and then return to feed their pups, repeating this
cycle for four consecutive months. By comparing at-sea behavior between
lactating and non-lactating females carrying microprocessor instruments, we
better understand the challenges of being a mother: they take shorter trips
to get food (to return to their pups as quickly as possible), spend less
time ashore (to start the cycle again as soon as possible), and modify
their diving behavior to collect more food. Now that is a GREAT mom!

*About the presenter:*
Dr. Renato Borras-Chavez is a scientist from Chile. He obtained his
bachelor's degree in Marine Biology at Andres Bello University, Chile, and
his master's degree at San Diego State University, USA, working in kelp
forest ecology. He started working with marine mammals while pursuing his
Ph.D. at the Pontifical Catholic University of Chile. Since his first trip
to Antarctica 10 years ago, he has been there seven times, including three
long deployments for the project he is presenting here. After completing
his Ph.D., he worked for three years with the Chilean Antarctic Institute
(INACH), continuing his work on Antarctic pinnipeds. Today, he is a
research associate at the Center of Applied Ecology and Sustainability
(CAPES) and preparing to start a postdoctoral research project on leopard
seal ecology at Baylor University. He was also the president and national
representative of APECS Chile (the Association of Polar Early Career
Scientists) until this year.

Journal. This is your chance to engage with marine mammal scientists, learn
and ask questions from anywhere in the world. All are welcome.*

*About this talk:*
Florida manatees produce a variety of vocalizations, but their function is
unclear. The goal of this study was to investigate if manatee vocalizations
could be correlated with behavior. Multiple underwater microphones were
used to record manatee vocalizations in four different environments and
behaviors. Vocalizations recorded from resting, playing, stressed and
feeding wild animals were statistically tested to determine whether
vocalizations produced varied with behavior and calf presence. We also
measured the length, amount of noise, and changes in pitch (frequency
modulation) from vocalizations to investigate if they differed between
behaviors. Results suggest manatees vocalize using few call types and vary
the structure of the call based on behavior. One call type was correlated
with calf presence. Noisier calls were more frequently observed during
play. The most common call manatees produced are called squeaks. Squeaks
were longer in length and higher in frequency modulation when animals were
stressed. This research provides a foundation for comparative studies on
vocal behavior for the Florida manatee as well as studies on related
species.


*About the presenter:*Beth was born and raised in rural Pennsylvania and
first found her interest in marine life on a family vacation. Although she
initially went to school to be a registered nurse, after a few years of
nursing, she realized her true passion was marine biology.
She returned to school and got her undergraduate degree at Kutztown
University, Pennsylvania. After graduation, she volunteered with multiple
marine mammal and wildlife organizations and found her love of manatees
through an extended internship at Florida Fish and Wildlife (FWC). After
the internship, she completed her Master’s at Nova Southeastern University
where she first became involved in studying underwater sound (acoustics)
and manatee vocalizations. She completed her doctorate at Florida Atlantic
University in 2020. She is currently a post doctoral research fellow at
Mote Marine Laboratory in Sarasota, FL.
Dr. Brady’s primary research investigates vocal communication in manatee
species. In addition, she is studying manatee behavior, ecotourism impacts,
and recently started flying drones to assess the body condition of Florida
manatees.

About this talk:
Tissue biopsy sampling from cetaceans is essential to address many
biological, ecological, and behavioral questions that can ultimately inform
conservation. Yet, these research activities are invasive and their effect
therefore deserves to be investigated, particularly when performed over
young individuals (calves and juveniles). We assessed the short-term
response of humpback whales to boat approach and remote biopsy sampling in
a breeding ground according to age-class, sex, female reproductive status,
social context, sampling system, habitat, and repeated sampling with more
than 20 years of data collected in New Caledonia, South Pacific.

About the presenter:
I conduct research in animal behavior and spatial ecology, the way animals
interact with their environment, move and are distributed in geographical
space. In general, I seek to develop innovative and multidisciplinary
methods to study the multi-scale space use patterns of marine megafauna
species. I obtained my Masters degree in biology from the Ecole Normale
Supérieure in Lyon, France, and my PhD from Sorbonne Université studying
humpback whales in the South Pacific. I am currently a postdoc at the
Geospatial Ecology of Marine Megafauna lab, in the Marine Mammal Institute
(Oregon State University) although I am still based in New Caledonia where
I have lived and conducted research for seven years.

Journal. This is your chance to engage with marine mammal scientists, learn
and ask questions from anywhere in the world. All are welcome. *

*About this talk:*
The North Atlantic right whale was once present in both the Western and
Eastern North Atlantic, but has been extirpated from the Eastern North
Atlantic as a result of over a thousand years of whaling activities. It has
not been identified whether the animals that were once present in the
Eastern North Atlantic were a distinct population from the small group of
animals remaining today in the Western North Atlantic. Whaling records
suggest that animals in each of these regions may have had distinct
habitats, and possibly distinct populations, but what does genetic data
suggest? To address this question, we examined the genetic characteristics
of mitochondrial and nuclear DNA from 24 whale bones that range in age from
the 4th to the 20th century from around the North Atlantic. The
interpretation of the results is challenging, especially in a species that
has a long history of commercial whaling. However, all evidence combined
suggests that there was some degree of isolation between whales in each of
these two regions.

*About the presenter:*
Brenna Frasier is trained as a biologist and has studied marine mammals for
almost 25 years. Her research has focused on DNA analysis (primarily
ancient DNA) as a tool to address evolutionary, conservation and species
management questions with a particular interest in examining human use of
whales over the last millennia, whether for commercial or subsistence use.
This has culminated in projects examining 20th century whaling in
Antarctica, 16th century Basque whaling of right and bowhead whales along
the coast of Canada, and Norse whale-use over the past 1000 years around
the North Atlantic. While most of her work has focused on marine mammals
such as the North Atlantic right whale, beluga whale and Maritimes walrus,
she has also studied a variety of other animals, including the Sable Island
horses and several bat species.
Brenna has a passion for facilitating science and natural history learning
and communicating science in unique and natural environments which has led
to an array of other outreach-based projects including the development of
marine mammal and forensic science camps for teens, supporting a local
Forest School, writing for an array of audiences and completing field
guides to assist in Traditional Ecological Knowledge (TEK) studies on
marine mammals in the Canadian Arctic. She is currently the Curator of
Zoology of the Nova Scotia Museum, in Halifax, Nova Scotia, Canada.

Space on Zoom is limited to the first 500 attendees.
The talk will also be streamed live on the SMM Facebook page.

The SMM Seminar Editors' Select Series highlights the latest and most
exciting marine mammal science published in the Marine Mammal Science
Journal. This is your chance to engage with marine mammal scientists, learn
and ask questions from anywhere in the world.
All are welcome.

About this talk:
Baleen whales are the largest mammals on earth, but many questions about
their behaviour remain unanswered as they are submerged in the pelagic
environment. Among baleen whales, Bryde’s whales are one of the least
known. They are a non-migrating species of baleen whale with a wide
distribution. There is a small (∼ 135) year-round population of Bryde’s
whales in the Hauraki Gulf, New Zealand. We investigated their foraging
behaviour using data collected by an archival tag (DTAG2), boat-based
surveys, and drones. Our investigation not only revealed some interesting
aspects of their foraging behaviour, but also helped us to understand other
aspects of their lives such as rest.

About the presenter:
After receiving a masters in Marine Mammal Science from the University of
St Andrews, Sahar moved to New Zealand to do a PhD at the University of
Auckland. She completed her PhD on behavioural ecology of Bryde’s whales
and graduated in 2019. Since then, she has been doing something completely
different from marine mammal science; she is a co-founder at a tech
start-up in New Zealand. But, she thinks she hasn’t distanced herself from
science, still working on the papers from her PhD and believes she will get
back to marine science world full time in the future.

*About this talk:*
Franciscanas are the most endangered cetaceans in the Southwestern
Atlantic, where they are exposed to human activities such as artisanal
gillnet fishing and coastal development.  A need for information on ranging
patterns and behavior led to efforts to attach satellite-linked tags to
franciscanas in three bays in Argentina and Brazil during 2005-2013.
Residency, with small home ranges, occurred at each site.  Movements were
influenced by tides.  The dolphins used the entire water column, exposing
them to gillnets regardless of net depth.  Definable ranges facilitate
relating specific geographically based threats to appropriate population
units, increasing the potential for effective conservation.

*About the presenter:*
Randall Wells is a co-founder and directs the Chicago Zoological Society’s
Sarasota Dolphin Research Program, which conducts the world’s
longest-running study of a wild dolphin population.  He began studying
bottlenose dolphins in Sarasota Bay, Florida, as a high school volunteer at
Mote Marine Laboratory in 1970. Wells received his Bachelor’s degree in
Zoology from the University of South Florida in 1975, his Masters in
Zoology from the University of Florida in 1978, his PhD in Biology from the
University of California, Santa Cruz in 1986, and he was awarded a
post-doctoral fellowship with Woods Hole Oceanographic Institution in
1987.  Wells joined the Chicago Zoological Society staff in 1989.  Wells’
current research program uses a collaborative approach to examine the
behavior, social structure, life history, ecology, health, and population
biology of bottlenose dolphins along the central west coast of Florida,
with studies focusing on up to five concurrent generations of a locally
resident ~170-member dolphin community.  Recent research topics include the
effects of human activities on coastal dolphins, such as boat traffic,
fishing activities, human feeding of wild dolphins, and environmental
contaminants, and the impacts of other environmental disturbances such as
red tides.  He has conducted research on a variety of marine mammals
including Hawaiian spinner, Atlantic spotted, franciscana and other dolphin
species, vaquita porpoises, bowhead, humpback, blue, and gray whales, and
manatees. Wells has authored or co-authored 4 books and more than 285
peer-reviewed journal articles and book chapters.  He has been presenter or
co-author of more than 700 presentations at professional meetings or
invited public or university lectures.  Wells is past-President of the
international Society for Marine Mammalogy, and received the society’s
Kenneth S. Norris Lifetime Achievement Award in 2021.  Wells also serves on
the Committee of Scientific Advisors on Marine Mammals for the U.S. Marine
Mammal Commission, on the NOAA/USFWS Atlantic Scientific Review Group, and
he is past-chair of the NOAA/USFWS Working Group on Marine Mammal Unusual

Journal. This is your chance to engage with marine mammal scientists, learn

*About this talk:*
Marine mammals that rely on sound for important life functions, such as
echolocation, have evolved strategies to cope with auditory masking.
However, these may not be completely effective or cost-free, raising
concern for anthropogenic noise impacts. We investigated whether sperm
whales (N=15 individuals with sound- and movement recording tags) exhibited
behaviors consistent with masking during experimental exposures to navy
sonar and wind-generated surface noise. Compared to strong variation with
depth, foraging and echolocation behavior was relatively stable throughout
different sea states and sonar exposures. Nevertheless, small increase in
apparent click levels and reduced prey capture attempts were consistent
with our hypotheses for masking from sea state and sonar.

*About the presenter:*
Dr Saana Isojunno is behavioral ecologist at the University of St Andrews,
Scotland, based at the Centre for Research into Ecological and
Environmental Modelling (CREEM) but also working closely with the Sea
Mammal Research Unit (SMRU). She majored in fisheries and hydrobiology
(University of Jyvaskylä, Finland), before she moved to St Andrews where
she gained a masters in Marine Mammal Science in 2008, and PhD on sperm
whale foraging behavior and anthropogenic disturbance in 2014. Her research
strives to better understand how individuals respond to, and cope with,
environmental stressors and human activities. She focuses on applied
questions such as the effects of underwater noise and marine renewables,
but drawing from fundamental science such as the non-consumptive effects of
predators on prey.

*About this talk:*
The algal-produced neurotoxins domoic acid and saxitoxin permeate food webs
in the Alaskan Arctic and subarctic, potentially threatening the health of
high-level consumers. As water temperatures continue to rise in the Arctic
due to climate change, marine mammal exposures to these toxins may be
increasing as warmer ocean temperatures are more favorable for toxic algal
blooms. We analyzed domoic acid and saxitoxin presence and levels in
samples from the gastrointestinal tracts of almost one thousand Alaskan ice
seals harvested over fifteen years for subsistence purposes. Though no
clinical signs of health impacts were reported in harvested seals, one or
both toxins were found in all four species studied. Additionally, the
number of ice seal stomach content samples containing DA increased over
time in seals collected in the Bering Sea, suggesting an increase in toxin
prevalence in the region. Increasing toxin exposure in ecologically and
culturally critical Alaskan species, including ice seals, raises concerns
for potential health impacts if toxins continue to increase in the future.

*About the presenter:*
Alicia Hendrix is a PhD student in the University of Washington’s
Environmental Toxicology program. She has a Bachelor’s degree in Biology
from Scripps College. Her work has taken her throughout the Americas,
studying threats to marine ecosystems as diverse as the Pacific intertidal
and the Mesoamerican Barrier Reef with organizations including the Cape
Eleuthera Institute and the NOAA Fisheries. Her research interests include
toxin and toxicant impacts on wildlife and human health, and methods for
promoting ecosystem resilience in the face of new threats. She has mentored
or taught students at elementary, high school, and undergraduate levels,
and believes strongly in building partnerships with coastal communities to
amplify regional voices and knowledge.

*About this talk:*
Social connectivity is important for measuring the fitness of common
bottlenose dolphins because social relationships can enhance survival,
reproduction and foraging success.  Human-related injuries such as boat
strikes or fishing gear entanglements can potentially remove an individual
from its association network and disrupt these relationships. Using data
from the long-term resident dolphin community in Sarasota Bay, Florida, we
investigated how these injuries affect the dolphins' social associations by
examining the differences in their social networks before and after injury.
We found that while injured dolphins were found in groups of similar size
to those prior to their injury, their number of preferential associations
(i.e., their best friends) seemed to decline immediately after injury but
were often regained within two years following injury. An individual’s
strongest associations, namely those between mothers and calves and those
between male alliance partners, remained stable before and after injury.
Because dolphins rely on these relationships for survival, increased
occurrence of injury from boating and fishing may put the animals at
greater risk for long-term survival, including making them more vulnerable
to predation.

*About the presenter:*
Michelle Greenfield is a veterinary student at the Cornell University
College of Veterinary Medicine (2023). She holds a Bachelor of Arts degree
in ecology and evolutionary biology from Princeton University where she

Journal. This is your chance to engage with marine mammal scientists, learn
and ask questions from anywhere in the world. All are welcome. *

*About this talk:*
Killer whale call repertoires can provide information on social connections
among groups and populations. Killer whales in Iceland and Norway exhibit
similar ecology and behavior, are genetically related, and are presumed to
have been in contact before the collapse of the Atlanto-Scandian herring
stock in the 1960s. However, photo-identification suggests no recent
movements between Iceland and Norway but regular movement between Iceland
and Shetland. We used acoustic recordings collected in Iceland, Norway, and
Shetland to undertake a comprehensive comparison of the call repertoires of
Northeast Atlantic killer whales. Time and frequency parameters of calls
from Iceland and Norway were relatively similar but no call type matches
were confirmed between Iceland and Norway or Shetland and Norway. Three
call types matched between Iceland and Shetland. Therefore, these findings
agree with what is currently known of the movement patterns of these whales
but argue against past contact between Icelandic and Norwegian killer
whales, since call repertoires are thought to be maintained over time.

*About the presenter:*
Anna Selbmann is currently a PhD student at the University of Iceland
investigating killer whale acoustic behaviour and interspecific
interactions between pilot whales and killer whales. She gained a BSc in
Marine Vertebrate Zoology from Bangor University (UK) in 2015 and completed
her Masters of Biology at the University of Iceland in 2019 investigating
the call repertoire of Icelandic killer whales and comparing it to the
repertoire of Norwegian killer whales.

*About this talk:*
We used high-resolution acoustic and movement tags (Dtags) to analyse the
echolocation behaviour of fish-eating killer whales during pursuit and
capture of salmon prey. Whales produced more echolocation trains and had
faster clicking rates prior to catching salmon versus afterward, confirming
the importance of echolocation in prey detection and tracking. Extremely
rapid click sequences (buzzes) occurred in the lead-up to salmon captures
at depths typically exceeding 50 m, and were likely used for close-range
prey targeting. Distinctive crunching sounds related to prey handling
occurred at shallow depths following captures, matching observations that
whales surfaced with salmon prior to eating them and often shared their
prey.

*About the presenter: *
I received my B.Sc. majoring in Biology and Anthropology from the
University of Victoria in 2007. During my undergrad I also participated in
the UVic Biology Co-op program and studied at the Bamfield Marine Sciences
Centre. From 2008-2010, I worked as a Technician with the Cetacean Research
Program of Fisheries and Oceans Canada (DFO) before returning to school and
completing my M.Sc. in 2014 at UBC’s Marine Mammal Research Unit under the
supervision of Dr. John Ford and Dr. Andrew Trites. My thesis investigated
the fine-scale foraging behaviour of resident killer whales using
suction-cup attached tags that recorded dive depth, body position and
acoustic behaviour of individual whales. I returned to work with DFO’s
Cetacean Research Program at the Pacific Biological Station in Nanaimo in
July 2014, and I’m currently a marine mammal Biologist with this group. My
job takes me throughout beautiful coastal British Columbia, Canada where
I’ve been lucky enough to participate in killer whale and sea otter census
surveys and offshore ship and aerial distance-sampling surveys for
cetaceans. Analytically, my recent work has focused on spatial density
modelling of survey data for cetacean species to estimate their
distribution and abundance. I also conduct assessments of killer whale diet
composition and prey sharing behaviour through field collection and
analysis of prey remains.

*About this talk:*
In Australasia, seasonal killer whale aggregations have been recently
discovered and they have known to also reside year-round in New Zealand
waters. However, there is currently limited information available about the
species in these regions and therefore effective conservation management
strategies are lacking. Here, we present the first study on the number of
killer whale populations and their connectivity in Australasia using DNA.
We discovered a minimum of three populations of killer whales, one in
tropical and a second in temperate Western Australia, and a third in New
Zealand. They each have distinct female-driven societies and appear to have
little movement between them with low number of breeders. These findings
can assist conservation management of these animals in the region.

*About the presenter: *
Isabella is currently a PhD Candidate in the Cetacean Ecology, Behaviour
and Evolution Lab and the Molecular Ecology Lab at Flinders University in
South Australia. She has over five years of experience researching
cetaceans, leading her to obtain a skillset predominantly in
photo-identification methods and using genetics to understand
population-level questions for conservation. Her research now focusses on
using genetics to broadly understand cetacean evolution, with a focus on
Australasian killer whales.

*About this talk:*
Sea otters were once abundant throughout the nearshore of the North
Pacific. The maritime fur trade left few remnant populations with low
genetic diversity. Subsequent reintroductions of otters resulted in several
new populations in North America. We sampled sea otters genetically from
Bering Island to California to evaluate genetic diversity, population
structure and geneflow. Genetic diversity was the highest in reintroduced
populations, population structure was greatest between California and all
other groups, and geneflow was evident between all populations except for
those at the ends of the range. The reintroductions are arguably the
greatest success in sea otter conservation.

*The SMM Seminar Editor's Select Series highlights the latest and most
exciting marine mammal science published in the Marine Mammal Science
Journal. This is your chance to engage with marine mammal scientists, learn
and ask questions from anywhere in the world. All are welcome. *

*About this talk*:
The use of drones has risen exponentially in recent years, following an
increasingly widespread use among hobbyists and researchers, although their
effects on wildlife behaviour are not always well known. Our project
studied the impact of drones on different species of arctic marine mammals,
including walruses, polar bears, belugas and harbour seals in Svalbard, in
order to provide management advice to the local authorities. Over the
course of several field expeditions, the team used a range of drone models,
and tested different approach strategies and flight altitudes. We also
measured the sound emitted by the drones to help us evaluate the impact of
different type of flights on wildlife. Overall, harbour seals reacted to
the drones from a distance of 80 m, while walruses reacted when flying
closer than 50 m. Flying manually, especially overflying or descending over
the animals, led to noisier flights and caused more disturbance than when
flying in automatic mode. Polar bears noticed the drones at distances over
300 m, especially with calm weather conditions, and belugas reacted
strongly when approaching the pods from the front, or at altitudes below 15
m. We recommend following trajectories that can be predicted by the
animals, such as straight-line or circular paths, and using flight planner
applications in order to minimise abrupt noises. Finally, events that took
place and conditions prior to a flight, such as the encounter of a
predator, may directly influence how wildlife reacts to drones, so we
advise drone pilots to follow a precautionary principle.

*About the presenter: *

[MARMAM] SMM Editor’s Select Series for April 15: Predicting the Effect of Climate Change on Food Requirements of an Iconic Arctic Species

2021-04-13 Thread Student Members-at-Large Society for Marine Mammalogy
Greetings MARMAM!

Join us on *15 April 2021 at 5 PM Pacific Time (1 AM UTC)* for the next SMM
Seminar Editor's Select Series: *What Does It Take To Power A Walrus?
Predicting the Effect of Climate Change on Food Requirements of an Iconic
Arctic Species*

*The SMM Seminar Editor's Select Series highlights the latest and most
exciting marine mammal science published in the Marine Mammal Science
Journal. This is your chance to engage with marine mammal scientists, learn
and ask questions from anywhere in the world. All are welcome.*

*About this talk:*
Climate change is rapidly altering the Arctic ecosystem, including dramatic
decreases in the extent of summer ice. Scientists are trying to predict the
effect of these environmental transformations on wildlife. This includes
the Walrus, an iconic, ice-dependent species that relies on stable ice
surfaces to rest and act as a base for foraging on nearby food beds.
Mathematical bioenergetic models are a typical tool that scientists use to
predict the food energy requirements of animals under different conditions,
and several such models have been constructed for walruses. However, these
models are only as accurate as the data that goes into them. This talk will
describe several studies that measured the costs of resting in water and
swimming in two juvenile walruses on loan to the Vancouver Aquarium. I will
describe what it was like to work with these boisterous, large animals on a
daily basis, the scientific challenges and opportunities they provided, and
what the resulting data tells scientists about the costs of global warming
on these animals.

*About the Presenter:*
Dr. David Rosen is Assistant Professor at the University of British
Columbia. His current research primarily investigates the bioenergetics
(energy requirements and expenditures) of marine mammals. Its focus is to
understand the root causes of population changes by investigating the
interactions between the physiology of individual animals and biotic and
abiotic environmental changes. The work directly contributes to the
conservation and management of marine resources, particularly those in
Arctic regions, where environmental change – including climate change and
fisheries impacts – is most evident.

*The event is f*ree to attend online on Zoom. Registration is required.

[MARMAM] SMM Editor’s Select Series for March 11: Impact of warm water anomalies on Guadalupe fur seal foraging habitat

2021-03-08 Thread Student Members-at-Large Society for Marine Mammalogy
Greetings MARMAM!

We invite everyone to join us this *Thursday, March 11, 2021 from 8-9:30PM
(EST)* for the Society for Marine Mammalogy Editor's Select Series
event:* Impact
of warm water anomalies on Guadalupe fur seal foraging habitat*

*The SMM Seminar Editor's Select Series highlights the latest and most
exciting marine mammal science published in the Marine Mammal Science
Journal. This is your chance to engage with marine mammal scientists, learn
and ask questions from anywhere in the world. All are welcome. *

*About this talk: *The Guadalupe fur seal (GFS), currently is recovering
from near extinction. As this species continues to recover, it is important
to understand how its foraging success may be affected by warm water and
other oceanographic anomalies in the northeastern Pacific. We assessed the
foraging ecology of the GFS over a period that was characterized by normal
(2013) ocean temperatures followed by warm conditions (2014–2016). We used
scat analysis to identify differences in GFS prey between 2013 and
anomalous years. The most important prey species among these years was the
jumbo squid, followed by the neon flying squid during warmer years. An
additional analysis based on stable isotope suggested a broader northerly
or offshore foraging areas during these anomalous conditions. Our findings
are an important step toward better understanding the impacts of climate
change on the recovery of the GFS

*About the Presenter:* Maria Jose Amador-Capitanachi is an MSc student at
the Instituto Politécnico Nacional

The event is free to attend but registration is required.
