Publication on diving metabolism
by Andreas Fahlman 06 Apr '23

06 Apr '23

Dear MARMAMers, My co-authors and I are pleased to share this new open-access publication: Fahlman A, Allen AS, Blawas A, Sweeney J, Stone R, Trainor R, Jensen FH, McHugh K, Allen JB, Barleycorn AA & Wells RS (2023). Surface and diving metabolic rates, and dynamic aerobic dive limits (dADL) in near- and off-shore bottlenose dolphins, Tursiops spp., indicate that deep diving is energetically cheap. Marine Mammal Science, 1-18. Abstract: High-resolution dive depth and acceleration recordings from nearshore (Sarasota Bay, dive depth < 30 m), and offshore (Bermuda) bottlenose dolphins (Tursiops spp.) were used to estimate the diving metabolic rate (DMR) and the locomotor metabolic rate (LMR, L O2/min) during three phases of diving (descent, bottom, and ascent). For shallow dives (depth ≤ 30 m), we found no differences between the two ecotypes in the LMR during diving, nor during the postdive shallow interval between dives. For intermediate (30 m < depth ≤ 100 m) and deep dives (depth > 100 m), the LMR was significantly higher during ascent than during descent and the bottom phase by 59% and 9%, respectively. In addition, the rate of change in depth during descent and ascent (meters/second) increased with maximal dive depth. The dynamic aerobic dive limit (dADL) was calculated from the estimated DMR and the estimated predive O2 stores. For the Bermuda dolphins, the dADL decreased with dive depth, and was 18.7, 15.4, and 11.1 min for shallow, intermediate, and deep dives, respectively. These results provide a useful approach to understand the complex nature of physiological interactions between aerobic metabolism, energy use, and diving capacity.

by Thaya Mirinda Dinkel 05 Apr '23

05 Apr '23

Dear firends, the Deutsches Meeresmuseum calls for volunteers to join trials in Denmark to study a harbour porpoise by-catch mitigation strategy, the PAL (Porpoise ALert). We are looking for motivated people to join in Fyns Hoved campaign in summer 2023 to observe the interaction of harbour porpoises with an experimental fishing net and take drone footage of the animals in the experimental set up. We look for people with previous experience in cetacean observation, ideally with some skills operating drones (not mandatory). Food and accomodation will be covered by the project, but costs for travel and insurance will have to be covered by the volunteers. Minimum time to volunteer will be two weeks. Preference will be given to volunteers that can stay longer periods of time. Dates: 07.07.2023 – 27.08.2023 For more information on the project follow the links: https://www.deutsches-meeresmuseum.de/en/science-research/projects/current-… https://www.thuenen.de/en/institutes/baltic-sea-fisheries/projects/fisherie… Please send us a short email introducing yourself and telling us why you want to join the project together with your CV to: thaya.dinkel(a)thuenen.de and Ole.Meyer-Klaeden(a)meeresmuseum.de We look forward to meeting you!

New publication: Acoustic recording of false killer whale (Pseudorca crassidens) from Mexico (L)” in The Journal of the Acoustical Society of America
by Raul Rio Ribeiro 03 Apr '23

03 Apr '23

Dear MARMAM readers, I am pleased to announce the publication of our new study entitled "Acoustic recording of false killer whale (Pseudorca crassidens) from Mexico (L)” in The Journal of the Acoustical Society of America (Vol.153, Issue 4). It may be accessed via the link below: Acoustic recording of false killer whale (Pseudorca crassidens) from Mexico (L) DOI: 10.1121/10.0017726 Raul Rio ABSTRACT: This study collected acoustic information on false killer whales (Pseudorca crassidens) in Mexican waters, close to Roca Partida Island, Revillagigedo Archipelago. In total, 321 whistles were collected after we found a group with at least ten individuals. The high prevalence of ascending contour types [upsweep (type I): 42.99%] contradicted the idea that false killer whales mostly produce constant whistles. Lack of well-established reproducibility criteria for whistle type categorization among studies may have generated results different from those expected for signal modu- lation. Future acoustic and ecological studies should be conducted to help clarify these findings and expand the lim- ited knowledge about this species.

Buying/loaning CPODS for the SAMBAH II project
by Ms Kylie Owen 03 Apr '23

03 Apr '23

Hey everyone, We would like to get in touch with anyone who may have CPODs that they are interested in loaning or selling to our consortium, for use in a large-scale monitoring project. The SAMBAH II project aims to determine the abundance of the Critically Endangered Baltic Proper harbour porpoise. For this, close to 300 stations over eight countries around the Baltic Sea will be monitored using CPODs, and we are currently short on the number of CPODs required to make this happen. If you have CPODs that you no longer use and would like to sell them or would be willing to loan equipment to the project during 2024/2025, please contact kylie.owen(a)nrm.se. Thanks for your help Kind Regards Kylie

New publication: Atlantic white-sided dolphin population genetics
by Marc-Alexander Gose 03 Apr '23

03 Apr '23

Dear MARMAM community, My co-authors and I are pleased to share our new publication: Gose, M.-A.; Humble E.; Brownlow A.; Mikkelsen B.; Loftus C.; Wall D.; Rogan E.; ten Doeschate M.; Davison N.; and Ogden R. Stranding collections indicate broad-scale connectivity across the range of a pelagic marine predator, the Atlantic white-sided dolphin (Lagenorhynchus acutus) in ICES Journal of Marine Science. Find the Open Access paper here: http://dx.doi.org/10.1093/icesjms/fsad050 Abstract Understanding the extent of population genetic connectivity in highly mobile marine species is vital for delineating management units. However, obtaining samples for generating genetic data is challenging for species inhabiting inaccessible pelagic waters. As a result, management strategies do not always align with underlying population biology. Marine strandings provide an accessible and cost-effective sample source for research on elusive cetaceans and can be used collaboratively among stranding networks to generate ecosystem-wide population genetic assessments. Here, we used samples collected from strandings and free-ranging individuals across the North Atlantic to investigate population structure, genetic diversity, and individual relatedness in the Atlantic white-sided dolphin (AWSD; Lagenorhynchus acutus), a widely distributed marine predator. Mitochondrial DNA sequences and nuclear DNA single-nucleotide polymorphisms showed a complete lack of population differentiation across the species' range, implying an unusual pattern of strong connectivity. No differences in genetic diversity among geographic regions and weak within-group relatedness further support the existence of species-wide panmixia in AWSD. This study emphasises the value of long-term stranding collections for cetacean research and has important implications for AWSD conservation management.
