[MARMAM] New publication in the journal Oceans

[Stephanie Norman]

My co-authors and I would like to announce the publication of our recent
article:

Antibiotic Resistance of Bacteria in Two Marine Mammal Species, Harbor
Seals and Harbor Porpoises, Living in an Urban Marine Ecosystem, the Salish
Sea, Washington State, USA

by Stephanie A. Norman, Dyanna M. Lambourn, Jessica L. Huggins, Joseph K.
Gaydos, Sandra Dubpernell, Susan Berta, Jennifer K. Olson, Victoria Souze,
Alysha Evans, Betsy Carlson, Mandi Johnson, Rachel Mayer, Cathy King,
Alyssa Scott

Abstract
The pervasive use of antibiotics in human medicine, veterinary medicine,
and agriculture can result in a significant increase in the spread and
environmental persistence of antibiotic resistance in marine ecosystems.
This study describes the presence and distribution of antibiotic-resistant
bacteria in Salish Sea harbor seals (*Phoca vitulina*) and harbor porpoises
(*Phocoena phocoena*) and evaluates species, age class, and geographic
differences in resistance patterns. Isolates from 95 dead-stranded animals
(74 seals/21 porpoises) were tested for resistance to a suite of 15
antibiotics. Of the 95 sampled, 85 (89%) (67 seals/18 porpoises)
successfully yielded 144 isolates, with 37% resistant to at least one
antibiotic and 26% multi-drug resistant (24% and 39% of seal and porpoise
isolates, respectively). Overall, and by study region, porpoises were
significantly more likely to harbor resistant organisms compared to seals.
Significant differences between age classes were noted for the antibiotics
amoxicillin, cephalexin, and cefovecin. Overall isolate resistance was
significantly greater in porpoises than seals for several individual
antibiotics. Multiple antibiotic resistance (MAR) indices greater than 0.2
were observed in 55% of multi-drug resistant isolates, suggesting seal and
porpoise exposure to anthropogenic pollution. The relatively high and
disparate prevalence of antibiotic resistance in these common, but
ecologically dissimilar, marine mammals reflects a potentially large
environmental pool of antibiotic resistant organisms in the Salish Sea or
inherently different resistance gene patterns between the two species.

[MARMAM] RAAlg - Regional Algarve Stranding Network (Southern Portugal)

[Ana Marçalo]

Dear all Marmam members,

On behalf of our team, I would like to announce that the regional Algarve
Stranding Network (RAAlg) has been re-activated.

We therefore attend any stranded cetaceans or marine turtles that strand
dead along the Algarve coast in Southern Portugal. We also developed a
responsive webpage, which allows citizens to register information on any
seen stranded animal. The alert is communicated to the team via email, and
provides a faster response so we can access the animal and sample it. This
unique page also provides information regarding our team, our work, results
and ID of species of animals that strand in our coast.

Check our website at www.raalg.pt.

We hope you enjoy our page.

Best wishes,

[MARMAM] New paper: A novel approach to foraging strategies in sea lions

[Jonas Schwarz]

Dear all,

My co-authors and I are happy to present our new paper titelt:
Individuality counts: A new comprehensive approach to foraging strategies of a 
tropical marine predator

The PDF is available open-access on Researchgate or direct from Oecologia:

https://www.researchgate.net/publication/348735245_Individuality_counts_A_new_comprehensive_approach_to_foraging_strategies_of_a_tropical_marine_predator
 

https://link.springer.com/article/10.1007/s00442-021-04850-w 


Abstract
Foraging strategies are of great ecological interest, as they have a strong 
impact on the fitness of an individual and can affect its ability to cope with 
a changing environment. Recent studies on foraging strategies show a higher 
complexity than previously thought due to intraspecific variability. To 
reliably identify foraging strategies and describe the different foraging 
niches they allow individual animals to realize, high-resolution multivariate 
approaches which consider individual variation are required. Here we dive into 
the foraging strategies of Galápagos sea lions (Zalophus wollebaeki), a 
tropical predator confronted with substantial annual variation in sea surface 
temperature. This affects prey abundance, and El Niño events, expected to 
become more frequent and severe with climate change, are known to have dramatic 
effects on sea lions. This study used high-resolution measures of depth, GPS 
position and acceleration collected from 39 lactating sea lion females to 
analyze their foraging strategies at an unprecedented level of detail using a 
novel combination of automated broken stick algorithm, hierarchical cluster 
analysis and individually fitted multivariate hidden Markov models. We found 
three distinct foraging strategies (pelagic, benthic, and night divers), which 
differed in their horizontal, vertical and temporal distribution, most likely 
corresponding to different prey species, and allowed us to formulate hypotheses 
with regard to adaptive values under different environmental scenarios. We 
demonstrate the advantages of our multivariate approach and inclusion of 
individual variation to reliably gain a deeper understanding of the adaptive 
value and ecological relevance of foraging strategies of marine predators in 
dynamic environments.

[MARMAM] New paper on the conservation status of snubfin dolphins in Western Australia

[Phil Bouchet]

Dear colleagues,

 

My co-authors and I are pleased to announce that the following paper is now 
available online:

 

Bouchet PJ, Thiele D, Marley SA, Waples K, Weisenberger F, Balanggarra Rangers, 
Bardi Jawi Rangers, Dambimangari Rangers, Nyamba Buru Yawuru Rangers, Nyul Nyul 
Rangers, Uunguu Rangers and Raudino H (2021) Regional Assessment of the 
Conservation Status of Snubfin Dolphins (Orcaella heinsohni) in the Kimberley 
Region, Western Australia. Front. Mar. Sci. 7:614852.

DOI: 10.3389/fmars.2020.614852

 

This work is the outcome of a long-term collaborative effort involving many 
dedicated individuals, including staff at the Western Australian Department of 
Biodiversity, Conservation and Attractions (DBCA) and numerous Traditional 
Owners / Indigenous Ranger Groups from the remote Kimberley region of Western 
Australia. Importantly, it is the reflection of the tireless efforts of Dr. 
Deborah Thiele, who has spent over a decade conducting surveys of snubfin 
dolphins to gain a better understanding of their ecology, distribution, and 
conservation needs. 

 

The paper was published as part of the Frontiers Research Topic entitled “Small 
Cetacean Conservation: Current Challenges and Opportunities” and can be 
downloaded freely from:

https://www.frontiersin.org/articles/10.3389/fmars.2020.614852/full

 

Abstract:

 

Implementing conservation measures for data-limited species is a fundamental 
challenge for wildlife managers and policy-makers, and proves difficult for 
cryptic marine animals occurring in naturally low numbers across remote 
seascapes. There is currently scant information on the abundance and habitat 
preferences of Australian snubfin dolphins (Orcaella heinsohni) throughout much 
of their geographical range, and especially within the Kimberley region of 
northern Western Australia. Such knowledge gaps curtail rigorous threat 
assessments on both local and regional scales. To address this and assist 
future conservation listings, we built the first comprehensive catalog of 
snubfin dolphin sightings for the Kimberley. We used these data to estimate the 
species’ extent of occurrence (EOO) and area of occupancy (AOO) along the 
region’s 7,000 km coastline, following a simple Bootstrap bivariate kernel 
approach to combine datasets of varying quality and quantify uncertainty. Our 
catalog consists of 1,597 visual detections of snubfin dolphins made over a 
period of 17 years (2004–2020) and collated from multiple sources, including 
online biodiversity repositories, peer-reviewed scientific articles, citizen 
science programs, as well as dedicated marine wildlife surveys with local 
Indigenous communities and Ranger groups. Snubfin dolphins were consistently 
encountered in shallow waters (<21 m depth) close to (<15 km) freshwater 
inputs, with high detection rates in known hotspots (e.g., Roebuck Bay, Cygnet 
Bay) as well as in coastal habitats suspected to be suitable (e.g., Prince 
Regent River and surrounds, King Sound, Doubtful Bay, Napier Broome Bay and the 
upper Cambridge Gulf). Bootstrap estimates of EOO and AOO were 38,300 (95% CI: 
25,451–42,437) km2 and 700 (656–736) km2 respectively, suggesting that snubfin 
dolphins in the Kimberley are likely Vulnerable under IUCN criteria B2 at a 
regional scale, in keeping with their global classification. Our study offers 
insights into the distribution of a vulnerable coastal cetacean species and 
demonstrates the value of integrating multiple data sources for informing 
conservation assessments in the face of uncertainty.

 

Please do not hesitate to contact me should you have any questions regarding 
our work.

 

Best wishes and stay safe,

Phil Bouchet

[MARMAM] New publication - Boats affect a dolphin-fisher cooperation

[Bianca Romeu]

Dear colleagues,

   We would like to share with you the last article from our research
group, published in Animal Conservation:

"Boat disturbance affects the acoustic behaviour of dolphins engaged in a
rare foraging cooperation with fishers"

Link to the full article:
https://zslpublications.onlinelibrary.wiley.com/doi/epdf/10./acv.12667

DOI: https://doi.org/10./acv.12667

Abstract

Acoustic behaviour is a key component of specialized foraging tactics for
many aquatic species, especially cetaceans. However, in recent decades the
natural environment has been increasingly exposed to a variety of
anthropogenic noise sources, with the potential to impact natural foraging
specializations dependent on acoustic communication. Here we evaluated
whether boat noise has the potential to impact a rare foraging tactic used
by individuals from a small population of the vulnerable Lahille’s
bottlenose dolphin (Tursiops truncatus gephyreus) specialized in
cooperation with artisanal fishers in southern Brazil. We tested whether
the presence of boats changed the acoustic behaviour of dolphins when
engaged in this cooperative foraging. We found that whistles and
echolocation click rates were lower when boats were present, suggesting
that cooperative foraging may potentially be reduced
or interrupted by the presence of boats. Whistle parameters changed in
response to the number, type and speed of boats, indicating a behavioural
change and acoustic masking. Locally, our results reinforce the need for
boat traffic regulations to minimize their impacts on these endangered
dolphins and their rare cooperative tactic. From a broad perspective, we
demonstrate how nonlethal impacts such as vessel disturbance can manifest
subtle changes in animals’ natural behaviour and, in this case, present an
insidious threat to a unique foraging specialization.

[MARMAM] FinShape Web App

[Eduardo Morteo]

Dear All, 

On behalf of the Development Team, I’m proud to present to you the FinShape web 
App:

http://finshape.morteo.mx 

This is the evolution of the FinShape v0.1 Desktop App, that appeared on the 
research paper by "Morteo et al. (2017), entitled “Phenotypic variation in 
dorsal fin morphology of coastal bottlenose dolphins (Tursiops truncatus) off 
Mexico":

https://peerj.com/articles/3415/ 

Based on the Weller (1998) method, it uses semi-automatic standardized and very 
precise (pixel) measurements on photographs to compute 2D ratios and fin’s 
surface area, which may be potentially useful to distinguish stocks and 
populations. 

Please give it a try and let us know what you think. 

The User Guide should be sufficient to operate the App; but if not, you may 
find details on the image selection criteria, and the full measuring process in 
the MSc thesis by Morteo (2004) (pages 20-24):

https://www.researchgate.net/publication/200836165_Dorsal_fin_morphological_differentiation_in_bottlenose_dolphins_Tursiops_truncatus_along_Mexican_coasts_an_adaptive_approach
 

 
If you find any issues, we’ll be more than glad to help you in any way we can 
to make the best use for this App.

We hope you enjoy it!
