[MARMAM] New publication: The functional role of Heaviside's dolphin (Cephalorhynchus heavisidii) rapidly pulsed signals

[Morgan J. Martin]

Dear MARMAM Members,

My co-authors and I are very pleased to announce the publication of
our new manuscript "To buzz or burst-pulse? The functional role of
Heaviside's dolphin, *Cephalorhynchus heavisidii,* rapidly pulsed
signals" published in the Journal of Animal Behaviour. This study is
the first to examine relationships between the surface and acoustic
behaviours of Heaviside's dolphins. The reference and abstract are
provided below. The article is available online now and will appear in
the April issue of Animal Behaviour.


Martin, M.J., Elwen, S.H., Kassanjee, R., Gridley, T. (2019). To buzz
or burst-pulse? The functional role of Heaviside's dolphin,
*Cephalorhynchus heavisidii,* rapidly pulsed signals. *Animal
Behaviour*. DOI: 10.1016/j.anbehav.2019.01.007

Abstract: Four groups of toothed whales have independently evolved to
produce narrowband high-frequency (NBHF) echolocation signals (i.e.
clicks) with a strikingly similar waveform and centroid frequency
around 125 kHz. These signals are thought to help NBHF species avoid
predation by echolocating and communicating at frequencies inaudible
to predators, a form of acoustic crypsis. Heaviside's dolphins produce
NBHF echolocation clicks in trains and often in rapid succession in
the form of buzzes. In addition, a second click type with a lower
frequency and broader bandwidth was recently described, typically
emitted in rapid succession in the form of burst-pulses. We
investigated the relationship between buzz and burst-pulse signals and
both surface behaviour (foraging, ‘interacting with the kayak’ and
socializing) and group size, using a multivariable regression on the
signal occurrence and signal count data. Signal occurrence and counts
were not related to group size in the regression analysis.
Burst-pulses were strongly linked to socializing behaviour, occurring
more often and more frequently during socializing and much less during
foraging. Buzz vocalizations were not strongly linked to a specific
behaviour although there was some evidence of an increase in
production during foraging and socializing. In addition, individual
level production rates of buzzes during foraging and socializing, and
burst-pulses during socializing decreased with increasing group size.
Temporally patterned burst-pulse signals were also identified, often
occurring within a series of burst-pulses and were directly linked to
specific events such as aerial leaping, backflipping, tail slapping
and potential mating. Our findings suggest Heaviside's dolphins have a
more complex communication system based on pulsed vocalizations than
previously understood, perhaps driven by the need to facilitate the
social interactions of this species.

[MARMAM] New publication: Impacts of past changes in sea ice on walrus diet

[Casey Clark]

MARMAM Members,

On behalf of my co-authors and myself, I am pleased to share our new paper, 
titled “Pacific walrus diet across 4000 years of changing sea ice conditions”, 
recently published in Quaternary Research. The paper is available here: 
https://goo.gl/SSKbqY 


Clark, C.T., L. Horstmann, A. de Vernal, A.M. Jensen, and N. Misarti. 2019. 
Pacific walrus diet across 4000 years of changing sea ice conditions. 
Quaternary Research. 1–17. doi:10.1017/qua.2018.140

Declining sea ice is expected to change the Arctic’s physical and 
biological systems in ways that are difficult to predict. This study used 
stable isotope compositions (δ13C and δ15N) of archaeological, historic, and 
modern Pacific walrus (Odobenus rosmarus divergens) bone collagen to 
investigate the impacts of changing sea ice conditions on walrus diet during 
the last ∼4000 yr. An index of past sea ice conditions was generated using 
dinocyst-based reconstructions from three locations in the northeastern Chukchi 
Sea. Archaeological walrus samples were assigned to intervals of high and low 
sea ice, and δ13C and δ15N were compared across ice states. Mean δ13C and δ15N 
values were similar for archaeological walruses from intervals of high and low 
sea ice; however, variability among walruses was greater during low-ice 
intervals, possibly indicating decreased availability of preferred prey. 
Overall, sea ice conditions were not a primary driver of changes in walrus 
diet. The diet of modern walruses was not consistent with archaeological low 
sea ice intervals. Rather, the low average trophic position of modern walruses 
(primarily driven by males), with little variability among individuals, 
suggests that trophic changes to this Arctic ecosystem are still underway or 
are unprecedented in the last ∼4000 yr.


I am happy to provide a PDF of the article upon request. Please email me at

[MARMAM] Cytokine expression in porpoises - Biomarkers for health assessment

[Lehnert-Sobotta, Kristina]

Dear colleagues,
My co-authors and I are pleased to share the recent publication of our paper in 
Environmental Pollution:

Lehnert, K., Siebert, U., Reißmann, K., Bruhn, R., McLachlan, M. S., Müller, 
G., ... & Beineke, A. (2019). Cytokine expression and lymphocyte proliferative 
capacity in diseased harbor porpoises (Phocoena phocoena)–Biomarkers for health 
assessment in wildlife cetaceans. Environmental Pollution 247, 783-791

Abstract: Harbor porpoises (Phocoena phocoena) in the North and Baltic Seas are 
exposed to anthropogenic influences including acoustic stress and environmental 
contaminants. In order to evaluate immune responses in healthy and diseased 
harbor porpoise cells, cytokine expression analyses and lymphocyte 
proliferation assays, together with toxicological analyses were performed in 
stranded and bycaught animals as well as in animals kept in permanent human 
care. Severely diseased harbor porpoises showed a reduced proliferative 
capacity of peripheral blood lymphocytes together with diminished transcription 
of transforming growth factor-β and tumor necrosis factor-α compared to healthy 
controls. Toxicological analyses revealed accumulation of polychlorinated 
biphenyls (PCBs), dichlorodiphenyldichloroethylene (DDE), and 
dichlorodiphenyltrichloroethane (DDT) in harbor porpoise blood samples. 
Correlation analyses between blood organochlorine levels and immune parameters 
revealed no direct effects of xenobiotics upon lymphocyte proliferation or 
cytokine transcription, respectively. Results reveal an impaired function of 
peripheral blood leukocytes in severely diseased harbor porpoises, indicating 
immune exhaustion and increased disease susceptibility.

[MARMAM] New publication: Depression chains in seafloor likely caused by deep-diving whales

[Helena Herr]

Dear colleagues,

on behalf of my co-authors I am pleased to announce the publication of the 
following paper:

Purser A, Herr H, Dreutter S, Dorschel B, Glud RN, Hehemann L, Hoge U, Jamieson 
AJ, Linley TD, Stewart HA and Wenzhöfer F (2019)
Depression chains in seafloor of contrasting morphology, Atacama Trench margin: 
a comment on Marsh et al. (2018), Royal Society Open Science 6(3):182053. 
http://dx.doi.org/10.1098/rsos.182053  
   
Abstract

This comment presents acoustic and visual data showing deep seafloor depression 
chains similar to those reported in Marsh et al. (R. Soc. open sci. 5: 180286), 
though from a different deep-sea setting. Marsh et al. present data collected 
during cruise JC120 from polymetallic nodule rich sites within the 
Clarion-Clipperton Fracture Zone (CCFZ), at water depths of between 3999 and 
4258 m. Within this comment, we present data collected with equivalent acoustic 
and imaging devices on-board the RV Sonne (SO261—March/April 2018) from the 
Atacama Trench, approximately 4000 m depth, which shows comparable depression 
chains in the seafloor. In contrast with the CCFZ observations, our study area 
was wholly free of polymetallic nodules, an observation therefore weakening the 
‘ballast collection’ by deep-sea diving mammals formation hypothesis discussed 
in their paper. We support their alternate hypothesis that if these features 
are indeed generated by deep-diving megafauna, then they are more likely the 
resultant traces of infauna feeding or marks made during opportunistic capture 
of benthic fish/cephalopods. We observed these potential prey fauna with lander 
and towed camera systems during the cruise, with example images of these 
presented here. Both the SO261 and JC120 cruises employed high-resolution 
sidescan systems at deployment altitudes seldom used routinely until the last 
few years during scientific deep-sea surveys. Given that both cruises found 
these depression chains in contrasting physical regions of the East Pacific, 
they may have a more ubiquitous distribution than at just these sites. Thus, 
the impacts of cetacean foraging behaviour on deep seafloor communities, and 
the potential relevance of these prey sources to deep-diving species, should be 
considered.


The open-access paper is available online at:

Kind regards

Helena

tale of defining sub-species from mitochondrial sequence monophyly." Molecular 
Phylogenetics and Evolution 135: 86-97.



ABSTRACT
The advent of massive parallel sequencing technologies has resulted in an 
increase of studies based upon complete mitochondrial genome DNA sequences that 
revisit the taxonomic status within and among species. Spatially distinct 
monophyly in such mitogenomic genealogies, i.e., the sharing of a recent common 
ancestor among con-specific samples collected in the same region has been 
viewed as evidence for subspecies. Several recent studies in cetaceans have 
employed this criterion to suggest subsequent intraspecific taxonomic 
revisions. We reason that employing intra-specific, spatially distinct 
monophyly at non-recombining, clonally inherited genomes is an unsatisfactory 
criterion for defining subspecies based upon theoretical (genetic drift) and 
practical (sampling effort) arguments. This point was illustrated by a 
re-analysis of a global mitogenomic assessment of fin whales, Balaenoptera 
physalus spp., published by Archer et al. (2013), which proposed to further 
subdivide the Northern Hemisphere fin whale subspecies, B. p. physalus. The 
proposed revision was based upon the detection of spatially distinct monophyly 
among North Atlantic and North Pacific fin whales in a genealogy based upon 
complete mitochondrial genome DNA sequences. The extended analysis conducted in 
this study (1676 mitochondrial control region, 162 complete mitochondrial 
genome DNA sequences and 20 microsatellite loci genotyped in 380 samples) 
revealed that the apparent monophyly among North Atlantic fin whales reported 
by Archer et al. (2013) to be due to low sample sizes. In conclusion, defining 
sub-species from monophyly (i.e., the absence of para- or polyphyly) can lead 
to erroneous conclusions due to relatively “trivial” aspects, such as sampling. 
Basic population genetic processes (i.e., genetic drift and migration) also 
affect the time to the most recent common ancestor and hence the probability 
that individuals in a sample are monophyletic.

[MARMAM] New publication: Minke whale acoustic presence in the eastern North Atlantic

[Denise Risch]

Dear List members,
My co-authors and I are happy to share our new manuscript: "Seasonal and
diel acoustic presence of North Atlantic minke whales in the North Sea",
published in Scientific Reports.

Risch, Denise, Samuel C. Wilson, Mathilde Hoogerwerf, Nienke CF van Geel,
Ewan WJ Edwards, and Kate L. Brookes. "Seasonal and diel acoustic presence
of North Atlantic minke whales in the North Sea." *Scientific Reports* 9,
no. 1 (2019): 3571.

Abstract:
Despite frequent records from other parts of the North Atlantic, minke
whales have never been
acoustically recorded in the North Sea. This study investigated the
detectability of pulse trains
previously associated with this species in other regions, in acoustic data
from ten sites along the east coast of Scotland. Since preliminary results
confirmed pulse train presence, subsequently, an automated detector was
applied to these data to record the seasonal and diel presence of minke
whale pulse trains. Minke whales were detected from May to November, with
most detections occurring in June, July and October. No acoustic detections
were made in December, January or in the month of April, whilst no data
were available for February and March. This pattern of acoustic presence
supports available visual data and suggested an absence of minke whales
from the study area during winter. Minke whale acoustic presence showed a
statistically significant diel pattern, with a detection peak during night
time. This study established the acoustic detectability of minke whales in
the North Sea and highlights the potential of using passive acoustic
monitoring to study the seasonal presence and spatial distribution of minke
whales in the North Sea and wider Northeast Atlantic.

I am happy to provide a pdf copy.
Cheers, Denise

[MARMAM] New paper on foraging behaviour of Weddell seals in the southern Weddell Sea

[Dominik Nachtsheim]

Dear MARMAM readers,

we are pleased to announce the publication of the following article in Progress 
in Oceanography:

Nachtsheim, D.A., Ryan, S., Schröder, M., Jensen, L., Oosthuizen, W.C., Bester, 
M.N., Hagen, W. and Bornemann, H., 2019. Foraging behaviour of Weddell seals 
(Leptonychotes weddellii) in connection to oceanographic conditions in the 
southern Weddell Sea. Progress in Oceanography 173, 165-179. 
doi:10.1016/j.pocean.2019.02.013

Abstract
The region of the Filchner Outflow System (FOS) in the southeastern Weddell Sea 
is characterized by intensive and complex interactions of different water 
masses. Dense Ice Shelf Water (ISW) emerging from beneath the ice shelf 
cavities on the continental shelf, meets Modified Warm Deep Water (MWDW) 
originating from the Antarctic Circumpolar Current at the sill of the Filchner 
Trough. These hydrographic features convert the FOS into an oceanographic key 
region, which may also show enhanced biological productivity and corresponding 
aggregations of marine top predators. In this context, six adult Weddell seals 
(Leptonychotes weddellii) were instrumented with CTD-combined satellite relay 
data loggers in austral summer 2014. By means of these long-term data loggers 
we aimed at investigating the influence of environmental conditions on the 
seals’ foraging behaviour throughout seasons, focussing on the local 
oceanographic features. Weddell seals performed pelagic and demersal dives, 
mainly on the continental shelf, where they presumably exploited the abundant 
bentho-pelagic fish fauna. Diurnal and seasonal variations in light 
availability affected foraging activities. MWDW was associated with increased 
foraging effort. However, we observed differences in movements and habitat use 
between two different groups of Weddell seals. Seals tagged in the pack ice of 
the FOS focussed their foraging activities to the western and, partly, eastern 
flank of the Filchner Trough, which coincides with inflow pathways of MWDW. In 
contrast, Weddell seals tagged on the coastal fast ice exhibited typical 
central-place foraging and utilized resources close to their colony. High 
foraging effort in MWDW and high utilization of areas associated with an inflow 
of MWDW raise questions on the underlying biological features. This emphasizes 
the importance of further interdisciplinary ecological investigations in the 
near future, as the FOS may soon be impacted by predicted climatic changes.

[MARMAM] New article how breath-holding affect breathing in dolphins?

[Andreas]

Dear all,
 
Me and my co-authors are pleased to share our recent publication with you:
 Fahlman, A., Brodsky, M., Miedler, S., Dennison, S., Ivančić, M., Levine, G., 
Rocho-Levine, J., Manley, M., Rocabert, J., Borque Espinosa, A., 2019. 
Ventilation and gas exchange before and after voluntary static surface 
breath-holds in clinically healthy bottlenose dolphins, Tursiops truncatus. J. 
Exp. Biol. 222, 1-9. doi: 10.1242/jeb.192211

The article describes changes in lung function and end-expired O2 following 
status surface apneas up to 5 min in the bottle nose dolphin. 
 
A B S T R A C T
We measured respiratory flow (V̇), breathing frequency (fR), tidal volume (VT), 
breath duration and end-expired O2 content in bottlenose dolphins (Tursiops 
truncatus) before and after static surface breath-holds ranging from 34 to 292 
s. There was considerable variation in the end-expired O2, VT and fR following 
a breath-hold. The analysis suggests that the dolphins attempt to minimize 
recovery following a dive by altering VT and fR to rapidly replenish the O2 
stores. For the first breath following a surface breath-hold, the end-expired 
O2decreased with dive duration, while VT and fR increased. Throughout the 
recovery period, end-expired O2 increased while the respiratory effort (VT, fR) 
decreased. We propose that the dolphins alter respiratory effort following a 
breath-hold according to the reduction in end-expired O2 levels, allowing 
almost complete recovery after 1.2 min.
