by Wellman, Michaela 15 Apr '26

15 Apr '26

The International Fund for Animal Welfare (IFAW) is currently accepting applications for Fall 2026 Marine Mammal Stranding Internships. IFAW Marine Mammal Stranding Internship Fall Session 2026 (First Week of September 2026 - Middle of January 2027) Complete Applications due: May 20th, 2026 Program Background IFAW is an international non-profit organization. This internship is based out of our International Operations Center in Yarmouth Port, Massachusetts, USA. IFAW's Marine Mammal Rescue (MMR) program is a federally authorized program dedicated to marine mammal stranding response on Cape Cod and southeastern Massachusetts. Our program strives to promote the conservation of marine mammal species and their habitat by improving the rescue and humane care of stranded marine mammals, advancing stranding science, and increasing public awareness through education. Cape Cod is a marine mammal stranding "hot spot," with an average of over 315 strandings occurring each year. These strandings include live and dead seals, whales, porpoises, and dolphins. In addition to stranding response, IFAW's MMR division has developed the Cetacean Intensive Care Unit (CICU) located at the Dolphin Rescue Center in Orleans, MA. CICU is a short-term holding facility (96 hours) that aims to provide rehabilitative care to dolphins and porpoises experiencing acute effects of stranding. Stranding Intern Duties * Stranding hotline coverage: answer calls, document reports, educate callers, dispatch volunteers, complete associated paperwork and enter data. * Marine mammal stranding response & necropsy: assist staff with all aspects of marine mammal stranding response, including live animal health assessment and supportive care, biological data collection, post-mortem examinations and sampling in both field and laboratory settings. * CICU operations: assist staff with aspects of CICU operations, including animal care (i.e. in-water support, assist during procedures, monitoring animal behavior etc.), CICU education and outreach, CICU readiness and cleaning, etc. Please note experiences will be opportunistic as cases arise.

New Publication: Availability of Chinook and Sockeye Salmon as Prey to Cook Inlet Beluga Whales
by Kate Lomac-MacNair 14 Apr '26

14 Apr '26

Dear MARMAM Community, My co-authors and I are pleased to announce our new publication in Frontiers in Marine Science: Bernard J, Templin B, Reimer A, McKinley T, Kellie K, Lomac-MacNair K, Blees M, Bender M, Adkison M, Polasek L and Quakenbush L (2026) Availability of Chinook and sockeye salmon as prey to Cook Inlet beluga whales. Front. Mar. Sci. 13:1726132. doi: 10.3389/fmars.2026.1726132 Abstract: Cook Inlet beluga whales (CIBW) are an endangered population of toothed whales in southcentral Alaska that have not shown signs of recovery over the past two decades. Since the 1999 harvest moratorium, the number of whales in the population has remained relatively stable, with the 2022 estimate at 381 whales. Despite extensive research efforts since its Endangered Species Act listing in 2008, the mechanisms limiting population growth remain poorly understood. Recent studies suggest prey availability could be a significant factor limiting reproduction. This study provides information relating to CIBW prey availability and identifies mechanisms that may limit CIBW population growth. We developed a database containing decades of Cook Inlet fisheries data collected by the Alaska Department of Fish and Game. We used annual run size and fish size data to establish indices of Chinook (*Oncorhynchus tshawytscha)* and sockeye salmon (*Oncorhynchus nerka*) availability within the Northern and Central Districts of Upper Cook Inlet. Data were not available to do the same for chum (*Oncorhynchus keta*), coho (*Oncorhynchus kisutch*), and pink salmon (*Oncorhynchus gorbuscha*) or for other important prey species, such as eulachon (*Thaleicthys pacificus*) and Pacific herring (*Clupea pallasii*), thus we focus on prey species Chinook and sockeye salmon. Here we summarize fisheries information archived in the database, estimate annual vital rates of CIBWs using an age-structured integrated population dynamics model, and correlate these vital rates to indices of prey availability (i.e., the annual biomass of select salmon runs based on available fisheries data). The biomass of Chinook salmon, the first species of salmon to arrive in Cook Inlet to spawn, declined significantly in the late 2000s. However, the biomass of other species, including sockeye salmon, has shown no clear trend since the 1980s. There were some indications that CIBW survival rates declined between 2005 and 2017, a period over which the biomass of Chinook and sockeye runs decreased in magnitude. However, it is not clear without additional information, such as a longer time series on CIBW survival rates and prey abundance, whether an increase in salmon availability would lead to an increase in CIBW population.

New publication: A sensitive liquid chromatography–tandem mass spectrometry analytical method of steroid hormones in small blubber samples from four whale species
by Clare Margaret Andvik 14 Apr '26

14 Apr '26

Dear MARMAM community, My co-authors and I are pleased to share our new open-access publication in Conservation Physiology: A sensitive liquid chromatography–tandem mass spectrometry analytical method of steroid hormones in small blubber samples from four whale species<https://academic.oup.com/conphys/article/14/1/coag023/8653515?login=false> https://doi.org/10.1093/conphys/coag023 Abstract: Steroid hormones can give an indication of stress, physiological health and reproductive status in whales; however, analysis is often limited by sample mass. We developed a sensitive analytical method using solid phase extraction–liquid chromatography–electrospray ionization–tandem mass spectrometry (LC–ESI–MS/MS) for the identification and quantification of eight steroid hormones (cortisol, cortisone, testosterone, androstenedione, progesterone, 11-deoxycortisol, 11-deoxycorticosterone and 17-hydroxyprogesterone) in small amounts of whale blubber (≤50 mg). Blubber biopsies were collected from stranded killer whales (Orcinus orca; n = 7), harbour porpoises (Phocoena phocoena; n = 3) and sperm whales (Physeter macrocephalus; n = 4), harvested common minke whales (n = 10; Balaenoptera acutorostrata) and free-living killer whales (n = 2) in Norway and the Barents Sea. Steroid hormones were separated using pentafluorophenyl propyl stationary phase and an optimized gradient programme with a total 20-min run. All samples (n = 26) were analysed at 50-mg sample mass, and a subset (n = 11) at 25 mg or lower. Low limit of detection and limit of quantification values resulted in high detection rates of hormones, and we found similar hormone concentrations between parallel samples and at the lowest tested sample mass (14 mg). Cortisol concentrations in sperm whales (4.3 ± 1.6 ng/g) were four times higher than stranded killer whales (1.1 ± 0.96 ng/g), which in turn were up to four times higher than free-living killer whales (0.23 ± 0.12 ng/g), harbour porpoise (0.64 ± 0.38 ng/g) and harvested minke whales (0.22 ± 0.13), possibly due to fatality type and duration of stress prior to death. We provide the first quantification of blubber steroid hormones in killer whale, minke whale, sperm whale and harbour porpoise, and in less than 50-mg sample mass. By minimizing sample mass without compromising precision or sensitivity, our method allows for steroid hormone analysis even on samples with limited availability, strengthening our ability to monitor and conserve marine mammal populations.

Front. Mar. Sci. 13:1775666. doi: Abstract Terrestrial and marine species are exhibiting distributional shifts due to climate change and resource availability. As food webs are impacted, some species have moved into areas of increased human activity, encountering anthropogenic hazards. A coastal marine species that undertakes a long migration between breeding and foraging ranges, the Eastern North Pacific (ENP) population of gray whales (Eschrichtius robustus) is especially vulnerable to changes. Subgroups of ENP gray whales, including the Pacific Coast Feeding Group and the (Puget) Sounders, have adapted to exploit alternative feeding grounds as prey availability declines in the Arctic. Novel to known migration phenology, gray whales have been observed seasonally since 2018 in San Francisco Bay (SF Bay), California. We evaluated subgroup identity and mortality of gray whales in SF Bay from 2018 - 2025 using photo-identification. Data were collected through vessel-based surveys, opportunistic effort, and community submissions. We identified 114 individual whales of which eight were matched to a subgroup, indicating gray whales utilizing SF Bay are not merely a range extension by foraging subgroups. Only four gray whales were resighted within SF Bay between years. Using photographs, 21 individuals were successfully matched to carcasses and a minimum mortality rate of 18% was determined. Blunt and/or sharp force trauma consistent with vessel strike was determined to be the cause of death for 30 of 70 carcasses, and for nine of 11 matched animals where a cause of death was determined. Sounder and PCFG matched whales were more likely to survive SF Bay than ENP individuals, though minimum length of stay did not influence mortality. This work confirms that gray whales entering SF Bay are highly susceptible to vessel strike mortality and highlights a crucial need to identify and implement adaptive management strategies to mitigate injuries and mortality as whales continue to utilize novel habitat.

In this regard, environmental DNA (eDNA) metabarcoding is an increasingly popular innovative and non-invasive genetic tool for marine biodiversity monitoring, particularly useful for assessing the populations of highly mobile species with a wide distribution range, such as cetaceans. In this study, we compared cetacean species detection and distri?bution patterns obtained through eDNA metabarcoding with the sighting records obtained during simultaneous traditional visual monitoring. A total of 258 seawater samples was analysed, collected at 129 sampling stations during the SCANS-IV survey carried out in oceanic waters of the North Atlantic Ocean. Nine cetacean species were identified by eDNA metabarcoding and ten by visual monitoring; three species were detected solely by eDNA, while four were exclusively detected by visual observation, demonstrating the complementarity of the two methods. The four most frequently sighted species were also the most frequently detected species in eDNA samples, showing similar detection frequencies and distribution patterns at broad and intermediate spatial scales. At a finer scale, however, species occurrence did not overlap between methods. Additionally, eDNA provided new insights into striped dolphin (*Stenella coeruleoalba*), which may be under-represented in traditional moni?toring data. Overall, the results support the use of eDNA metabarcoding as a valuable complementary monitoring tool for assessing cetacean diversity and distribution, providing additional information on species presence throughout the study area. This is particularly relevant for species that are rarely recorded visually and for which there is insufficient information to design and implement appropriate management strategies. Please do not hesitate to contact us if you have any questions regarding this work.

Tortolini, Joy S. Reidenberg, Ciro R. Mart?nez, Santiago J. Fern?ndez, Mariano A. Coscarella; Air?water interface calling behavior of southern right whales (*Eubalaena australis*) in Pen?nsula Vald?s, Argentina: A sound production?based approach. *J. Acoust. Soc. Am.* 1 April 2026; 159 (4): 3277?3290. https://doi.org/10.1121/10.0043369 Abstract: We describe an air?water interface calling behavior observed in southern right whales (SRWs; *Eubalaena australis*) in Golfo Nuevo, Pen?nsula Vald?s, Argentina. This behavior involves SRWs producing audible vocalizations at the surface, here termed ?interface vocalizations? (IFVs), which propagate simultaneously in-air and underwater. IFVs were documented through opportunistic visual observations combined with synchronized in-air and underwater recordings, complemented by citizen science videos. Twenty IFVs were recorded across eight events, with ten including fully synchronized acoustic data. Both in-air and underwater components are tonal, low-frequency signals with different harmonic structures and variable duration, perceived in air as ?foghorn?-like sounds. Behavioral and acoustic analysis indicates that IFVs are intentionally produced, voluntarily controlled, non-breathing-related vocalizations. All callers were adult whales observed across simple and complex social contexts. The findings support IFVs as a distinct sound category from those previously described for SRW, with anatomical production likely mediated by the laryngeal apparatus.

New publication: Air–water interface calling behavior of southern right whales (Eubalaena australis) in Península Valdés, Argentina: A sound production–based approach
by virginia tortolini 14 Apr '26

14 Apr '26

Dear MARMAM community, My co-authors and I are pleased to announce the publication of the following paper in Acoustical Society of America: Virginia M. Tortolini, Joy S. Reidenberg, Ciro R. Martínez, Santiago J. Fernández, Mariano A. Coscarella; Air–water interface calling behavior of southern right whales (*Eubalaena australis*) in Península Valdés, Argentina: A sound production–based approach. *J. Acoust. Soc. Am.* 1 April 2026; 159 (4): 3277–3290. https://doi.org/10.1121/10.0043369 Abstract: We describe an air–water interface calling behavior observed in southern right whales (SRWs; *Eubalaena australis*) in Golfo Nuevo, Península Valdés, Argentina. This behavior involves SRWs producing audible vocalizations at the surface, here termed “interface vocalizations” (IFVs), which propagate simultaneously in-air and underwater. IFVs were documented through opportunistic visual observations combined with synchronized in-air and underwater recordings, complemented by citizen science videos. Twenty IFVs were recorded across eight events, with ten including fully synchronized acoustic data. Both in-air and underwater components are tonal, low-frequency signals with different harmonic structures and variable duration, perceived in air as “foghorn”-like sounds. Behavioral and acoustic analysis indicates that IFVs are intentionally produced, voluntarily controlled, non-breathing-related vocalizations. All callers were adult whales observed across simple and complex social contexts. The findings support IFVs as a distinct sound category from those previously described for SRW, with anatomical production likely mediated by the laryngeal apparatus. These results highlight the plasticity of SRW acoustic behavior and the complexity of its sound production, raising questions about the potential biological, communicative, and adaptive roles of IFVs in dual-pathway signaling.

New publication: Environmental DNA (eDNA) metabarcoding as a complementary monitoring tool in cetacean visual surveys: from broad to fine-scale spatial analysis in open waters (Miguel Álvarez-González)
by Miguel Álvarez 14 Apr '26

14 Apr '26

Dear MARMAM community, On behalf of my co-authors and myself, I am pleased to share our new open-access publication in *Marine Environmental Research*, led by the Marine Megafauna Research Group (MegaMAR) of the Spanish Institute of Oceanography (IEO-CSIC): Álvarez-González, M., Saavedra, C., Rotllant, J., Pierce, G. J., Gutiérrez-Muñoz, P., Vázquez Bonales, J. A., & Suarez-Bregua, P. (2026). Environmental DNA (eDNA) metabarcoding as a complementary monitoring tool in cetacean visual surveys: from broad to fine-scale spatial analysis in open waters. *Marine Environmental Research*, 217, 107985 Access to the publication: https://doi.org/10.1016/j.marenvres.2026.107985 You can also find a short summary of this work on Instagram: https://www.instagram.com/p/DXHmrkslGHP/?utm_source=ig_web_copy_link&igsh=M… Abstract: Monitoring cetacean populations is essential for understanding the status of marine communities. In this regard, environmental DNA (eDNA) metabarcoding is an increasingly popular innovative and non-invasive genetic tool for marine biodiversity monitoring, particularly useful for assessing the populations of highly mobile species with a wide distribution range, such as cetaceans. In this study, we compared cetacean species detection and distribution patterns obtained through eDNA metabarcoding with the sighting records obtained during simultaneous traditional visual monitoring. A total of 258 seawater samples was analysed, collected at 129 sampling stations during the SCANS-IV survey carried out in oceanic waters of the North Atlantic Ocean. Nine cetacean species were identified by eDNA metabarcoding and ten by visual monitoring; three species were detected solely by eDNA, while four were exclusively detected by visual observation, demonstrating the complementarity of the two methods. The four most frequently sighted species were also the most frequently detected species in eDNA samples, showing similar detection frequencies and distribution patterns at broad and intermediate spatial scales. At a finer scale, however, species occurrence did not overlap between methods. Additionally, eDNA provided new insights into striped dolphin (*Stenella coeruleoalba*), which may be under-represented in traditional monitoring data. Overall, the results support the use of eDNA metabarcoding as a valuable complementary monitoring tool for assessing cetacean diversity and distribution, providing additional information on species presence throughout the study area. This is particularly relevant for species that are rarely recorded visually and for which there is insufficient information to design and implement appropriate management strategies. Please do not hesitate to contact us if you have any questions regarding this work.

Fresh off the press: Publication on inferring internal organ contaminant burden in cetaceans
by von Hellfeld, Rebecca 14 Apr '26

14 Apr '26

Dear marmam community, With the unique (and tragic) occurrence of long-finned pilot whale mass stranding events, we have been given the rare opportunity to assess the potential use of skin as indicator for internal organ mercury burden in these animals. Removing the usual ecological and life-history variation that is inherent with single animal strandings, we were able to determine a relationship between the skin and liver mercury burden in a group of 54 pilot whales that stranded in 2023. I would greatly appreciate if this article could be shared further, and of course am more than happy to discuss the work in more detail if anyone is interested: https://doi.org/10.1111/mms.70170 Best wishes, Rebecca von Hellfeld ________________________________ Dr Rebecca von Hellfeld Postdoctoral Researcher University of Aberdeen School of Biological Science Environmental Modelling Group .
