Seeking MMOs for deployment on expedition tour vessels in the Antarctic Peninsula.
by Angus Henderson 11 Jan '21

11 Jan '21

These positions are unpaid at this stage, however, all travel to and from departure locations, food and accommodation costs will be covered. Deployments are across the Antarctic summer period, for a period of 8-12 weeks (further details below). *Brief Background* Representing the most rapidly warming region of Antarctica, the western Antarctic Peninsula (WAP) has a rapidly growing tourist industry and krill fishery (Bender et al., 2016; Schumann et al., 2013; Spence et al., 2017). Its ecological significance has been recognised internationally and is the focus of efforts to establish a Marine Protected Area. As many species recover from past exploitation, it is important to understand the patterns of distribution and relative abundance of marine predators on regional scales. While considerable effort has been expended on understanding key land-based krill predators such as penguins and seals (e.g., Boyd, 2002), there has been wide acknowledgement that information on the temporal and spatial distribution and abundance of cetaceans and other marine mammals not amenable to land-based study is lacking (IWC Report 2019). Antarctic whale stocks were hunted to commercial extinction in 20th century (Rocha et al., 2014) and are understood to be recovering variably (e.g., for humpback whales, *see* Constantine et al., 2014; Fleming and Jackson, 2011; Noad et al., 2019; Olavarría et al., 2007). Yet relatively little is known of the abundance and distribution of baleen whales in the Southern Ocean foraging grounds. Distance sampling sets a gold standard for estimating marine mammal abundance and distribution (Williams et al., 2006). Yet broad-scale distance sampling surveys are prohibitively expensive in remote Southern Ocean waters and often produces only one survey estimate per season, that is subsequently used to characterise the entirety of that season. With commitments from several Antarctic tour operators, we set out to build on the pilot survey program initiated during the 2019-2020 season by standardising a scientifically peer-reviewed distance sampling protocol for estimation of at-sea cetacean abundance and distribution. Specific Aims: (i) Can platforms of opportunity-based distance sampling efforts be improved and standardised in order to contribute to understanding Southern Ocean cetacean status and trends. (ii) What physical ocean properties, environmental variables and/or krill predictors drive cetacean abundance and distribution at temporal scales ranging from within-season to interannual. (iii) What is the total consumption rate of krill by baleen whales relative to land-based krill predators and human krill harvest, and how does this relate to what we know of krill abundance and distribution in time and space? *The roles* We are seeking expressions of interest and commitments (where possible) from volunteers with experience as marine mammal observers or those interested in becoming one. This is your opportunity to be one of the very few people in the world that go to Antarctica. You will have exposure to the wealth of wildlife and stunning landscapes that make this part of the Southern Ocean so special and the opportunity to ‘be a tourist’ at times during the voyage (potentially including landings). Sets of two observers (one trained/experienced lead MMO and one in training MMO) will be deployed from Ushuaia and Punta Arenas on expedition tour vessel (200-500 passengers) across the Antarctic summer (Nov-March) in the 2021/22 and 2022/23 season. We are seeking a commitment of 8-12 weeks; this will include several (3-6) voyages to the Antarctic Peninsula (potentially via South Georgia, the Falkland islands/ Islas Malvinas and/or South Orkney Islands), aboard tour vessels. Preference will be given to residents of Chile and Argentina, and those in closer proximity to voyages departure locations (Ushuaia and Punta Arenas). Observers will take distance sampling measurements of whales and other marine mammals from the bridge of the vessels. MMOs will need to remain focused and on task for many hours, and at times work to weather windows across an 18-hour day. It is critical MMOs are organised, focused, take accurate field recording, and remain on task. Lead MMOs will be responsible for dictating field effort in response to weather, ensuring quality control and data management. Both MMOs will also be required to give a seminar/lecture to guests on board the vessel as part of our agreement in securing berths for observers. MMOs will be required to complete a basic level of induction and training (provided), including the study of marine mammals and birds of the south-east Atlantic sector of the Southern Ocean. *Requirements* · Professional attitude · Excellent verbal, written and interpersonal communication skills · Self-motivated with attention to detail · Must have the ability to conduct tasks independently · Ability to maintain focus and input accurate data · Knowledge of marine ecosystems · High stamina and enthusiasm for the role · Tertiary education in marine science (or another related field) · Fluent in English, writing and speaking. Preference for those with experience · In taking distance sampling measurements · In marine mammal/sea-bird observation at-sea · Identifying Southern Ocean seabirds · At sea Preference to residents of Argentina and Chile and they are encouraged to apply. To register your expression of interest/apply please reply with a cover letter stating why you want the role, how your skills and experience apply and what you hope to get out of it (300-500 words) and a resume detailing your experience (1 page) including the name and contact details of 2 references and/or a short letter of recommendation.

New publication on respiratory sinus arrhythmia in bottlenose dolphins
by Ashley Blawas 11 Jan '21

11 Jan '21

Hi MARMAM-ers! My co-authors and I are pleased to share our recently published article: Respiratory sinus arrhythmia and submersion bradycardia in bottlenose dolphins (Tursiops truncatus). Ashley M. Blawas, Douglas P. Nowacek, Austin S. Allen, Julie Rocho-Levine, Andreas Fahlman. Journal of Experimental Biology 2021 224: jeb234096 doi: 10.1242/jeb.234096. Link: https://jeb.biologists.org/content/224/1/jeb234096 Abstract: Among the many factors that influence the cardiovascular adjustments of marine mammals is the act of respiration at the surface, which facilitates rapid gas exchange and tissue re-perfusion between dives. We measured heart rate (fH) in six adult male bottlenose dolphins (Tursiops truncatus) spontaneously breathing at the surface to quantify the relationship between respiration and fH, and compared this with fH during submerged breath-holds. We found that dolphins exhibit a pronounced respiratory sinus arrhythmia (RSA) during surface breathing, resulting in a rapid increase in fH after a breath followed by a gradual decrease over the following 15–20 s to a steady fH that is maintained until the following breath. RSA resulted in a maximum instantaneous fH (ifH) of 87.4±13.6 beats min−1 and a minimum ifH of 56.8±14.8 beats min−1, and the degree of RSA was positively correlated with the inter-breath interval (IBI). The minimum ifH during 2 min submerged breath-holds where dolphins exhibited submersion bradycardia (36.4±9.0 beats min−1) was lower than the minimum ifH observed during an average IBI; however, during IBIs longer than 30 s, the minimum ifH (38.7±10.6 beats min−1) was not significantly different from that during 2 min breath-holds. These results demonstrate that the fH patterns observed during submerged breath-holds are similar to those resulting from RSA during an extended IBI. Here, we highlight the importance of RSA in influencing fH variability and emphasize the need to understand its relationship to submersion bradycardia.

New publication on genetic and demographic history of Mediterranean monk seals
by Alexandros A. Karamanlidis 11 Jan '21

11 Jan '21

Dear MARMAM Readers, My co-authors and I are pleased to announce the publication of our recent article in Scientific Reports Karamanlidis, A. A., T. Skrbinšek, G. Amato, P. Dendrinos, S. Gaughran, P. Kasapidis, A. Kopatz and A. V. Stronen (2021). "Genetic and demographic history define a conservation strategy for Earth’s most endangered Pinniped, the Mediterranean monk seal *Monachus monachus*." Scientific Reports. 11:373. https://doi.org/10.1038/s41598-020-79712-1 ABSTRACT: The Mediterranean monk seal *(Monachus monachus) *is a flagship species for marine conservation, but important aspects of its life history remain unknown. Concerns over imminent extinction motivated a nuclear DNA study of the species in its largest continuous subpopulation in the eastern Mediterranean Sea. Despite recent evidence of partial subpopulation recovery, we demonstrate that there is no reason for complacency, as the species still shares several traits that are characteristic of a critically endangered species: Mediterranean monk seals in the eastern Mediterranean survive in three isolated and genetically depauperate population clusters, with small effective population sizes and high levels of inbreeding. Our results indicated male philopatry over short distances, which is unexpected for a polygynous mammal. Such a pattern may be explained by the species’ unique breeding behavior, in which males defend aquatic territories near breeding sites, while females are often forced to search for new pupping areas. Immediate action is necessary to reverse the downward spiral of population decline, inbreeding accumulation and loss of genetic diversity. We propose concrete conservation measures for the Mediterranean monk seal focusing on reducing anthropogenic threats, increasing the population size and genetic diversity, and thus improving the long-term prospects of survival.

The project is structured on an annual basis, to obtain data not only on the distribution during the Summer, but also changes during the different seasons. The study is already providing very interesting information about this community inside the study area, especially about its social organisation, abundance of individuals, distribution, and movements also outside the region. Moreover, our dataset includes data on several cetaceans species and also about other marine fauna such as Mediterranean shearwaters (*Puffinus yelkouan)*, Scopoli’s shearwaters (*Calonectris diomedea*), Northern gannets (*Morus bassanus*), Sandwich terns (*Thalasseus sandvicensis*), sunfish (*Mola mola*) among others. Surveys are carried out in coastal waters onboard a dedicated zodiac (6 m inflatable boat) around 10 times per month. Training will focus on collecting photo for photo-ID purposes, environmental, marine traffic, geographical (GPS) and dolphins' behavioural data. Land-based surveys take place in Imperia, in 2 different locations with the aim of collecting data on the presence/absence of dolphins, fishing boats in activity and marine birds. Fieldwork is a great opportunity to get involved and improve skills on cetaceans’ and marine biodiversity’s research. Both land-based and zodiac surveys are weather dependent, and their number can change each month.

New Publication: Molting strategies of Arctic seals drive annual patterns in metabolism
by Nicole Thometz 09 Jan '21

09 Jan '21

Dear Colleagues, My co-authors and I are very pleased to announce the publication of the following article in Conservation Physiology: Thometz, NM, Hermann-Sorensen, H, Russell, B., Rosen, DAS, Reichmuth, C (2021) “Molting strategies of Arctic seals drive annual patterns in metabolism.” Conservation Physiology. 9(1): coaa112; doi:10.1093/conphys/coaa112. Abstract: Arctic seals, including spotted (*Phoca largha*), ringed (*Pusa hispida*) and bearded (*Erignathus barbatus*) seals, are directly affected by sea ice loss. These species use sea ice as a haul-out substrate for various critical functions, including their annual molt. Continued environmental warming will inevitably alter the routine behavior and overall energy budgets of Arctic seals, but it is difficult to quantify these impacts as their metabolic requirements are not well known—due in part to the difficulty of studying wild individuals. Thus, data pertaining to species-specific energy demands are urgently needed to better understand the physiological consequences of rapid environmental change. We used open-flow respirometry over a four-year period to track fine-scale, longitudinal changes in the resting metabolic rate (RMR) of four spotted seals, three ringed seals and one bearded seal trained to participate in research. Simultaneously, we collected complementary physiological and environmental data. Species-specific metabolic demands followed expected patterns based on body size, with the largest species, the bearded seal, exhibiting the highest absolute RMR (0.48 ± 0.04 L O2 min−1) and the lowest mass-specific RMR (4.10 ± 0.47 ml O2 min−1 kg−1), followed by spotted (absolute: 0.33 ± 0.07 L O2 min−1; mass-specific: 6.13 ± 0.73 ml O2 min−1 kg−1) and ringed (absolute: 0.20 ± 0.04 L O2 min−1; mass-specific: 7.01 ± 1.38 ml O2 min−1 kg−1) seals. Further, we observed clear and consistent annual patterns in RMR that related to the distinct molting strategies of each species. For species that molted over relatively short intervals—spotted (33 ± 4 days) and ringed (28 ± 6 days) seals—metabolic demands increased markedly in association with molt. In contrast, the bearded seal exhibited a prolonged molting strategy (119 ± 2 days), which appeared to limit the overall cost of molting as indicated by a relatively stable annual RMR. These findings highlight energetic trade-offs associated with different molting strategies and provide quantitative data that can be used to assess species-specific vulnerabilities to changing conditions.

New publication: Long-term associations among male sperm whales
by Hayao Kobayashi 08 Jan '21

08 Jan '21

Dear MARMAM Readers, My co-authors and I are pleased to announce the publication of our article: Citation: Kobayashi H, Whitehead H, Amano M (2020) Long-term associations among male sperm whales (*Physeter macrocephalus*). PLoS ONE 15(12): e0244204. https://doi.org/10.1371/journal.pone.0244204 Abstract Little is known about the social structure of male sperm whales (*Physeter macrocephalus*) after they leave their natal units. While previous studies found no evidence for preferred associations among males, the observation of mass-strandings consisting exclusively of males, suggest that they have strong social bonds. To investigate the social associations among male sperm whales, we used half-weight index of association, permutation tests and standardized lagged association rate models on a large photo-identification database collected between 2006 and 2017 in Nemuro Strait, Japan. Our results suggest that while male sperm whales are not as social as females, they do form long-term associations, have preferred companionship, and forage in social proximity to each other. The best-fitting model to the standardized lagged association rate showed that associations among males last for at least 2.7 years and as most males leave the area after 2 years, associations may last for longer. Twenty dyads were observed associating over more than 2 years, for a maximum 5 years. One dyad was observed associating on 19 different days and clustered on 7 different days. Male associations may function to enhance foraging or to fend off predators. Such relationships seem to be adapted to a pelagic habitat with uncertain resource availability and predation pressure.

Dear Marmamers, The following paper has been published: Gómez-Hernández, I., Serran, A., Becerril-Gómez, C., Basañez-Muñoz, A. & Naval-Ávila, C. 2020. Prevalence and relative abundance of barnacles Xenobalanus globicipitis of the bottlenose dolphin Tursiops truncatus populations in the southern Gulf of Mexico. Revista de Biología Marina y Oceanografía. 55 (2): 172-176. DOI: https://doi.org/10.22370/rbmo.2020.55.2.2503 Abstract Xenobalanus globicipitis is a commensal barnacle located on cetacean fin edges. The commensal-host interaction between Xenobalanus globicipitis and the bottlenose dolphin (Tursiops truncatus) has been poorly studied in Mexico. The main objective was to estimate the relative barnacle prevalence and abundance in bottlenose dolphins in three areas and seasons of the Gulf of Mexico. Tamiahua zone showed the higher prevalence (42.4%) and relative abundance (0.60 barnacles/individual/hr-1) compared to Tuxpan and Nautla zones. Whereas, in dry season there were higher prevalence (55.6%) and relative abundance (0.53 barnacles/ individual/hr-1) than rainy and winter storm seasons. Therefore, zones and seasons of the Gulf of Mexico influence the barnacle- dolphin interactions.

Happy new year MARMAM-ers! My collaborators and I are pleased to announce the publication of our recent article, "An assessment of temporal, spatial and taxonomic trends in harmful algal toxin exposure in stranded marine mammals from the U.S. New England coast", in PLOS ONE. Abstract: Despite a long-documented history of severe harmful algal blooms (HABs) in New England coastal waters, corresponding HAB-associated marine mammal mortality events in this region are far less frequent or severe relative to other regions where HABs are common. This long-term survey of the HAB toxins saxitoxin (STX) and domoic acid (DA) demonstrates significant and widespread exposure of these toxins in New England marine mammals, across multiple geographic, temporal and taxonomic groups. Overall, 19% of the 458 animals tested positive for one or more toxins, with 15% and 7% testing positive for STX and DA, respectively. 74% of the 23 different species analyzed demonstrated evidence of toxin exposure. STX was most prevalent in Maine coastal waters, most frequently detected in common dolphins (Delphinus delphis), and most often detected during July and October. DA was most prevalent in animals sampled in offshore locations and in bycaught animals, and most frequently detected in mysticetes, with humpback whales (Megaptera novaeangliae) testing positive at the highest rates. Feces and urine appeared to be the sample matrices most useful for determining the presence of toxins in an exposed animal, with feces samples having the highest concentrations of STX or DA. No relationship was found between the bloom season of toxin-producing phytoplankton and toxin detection rates, however STX was more likely to be present in July and October. No relationship between marine mammal dietary preference and frequency of toxin detection was observed. These findings are an important part of a framework for assessing future marine mammal morbidity and mortality events, as well as monitoring ecosystem health using marine mammals as sentinel organisms for predicting coastal ocean changes.
