New publication: Evidence for social transmission of foraging behaviour in the Australian sea lion Hi All, Myself and co-authors are excited to share our latest paper: Evidence for social transmission of foraging behaviour in the Australian sea lion https://connectsci.au/zo/article/74/2/ZO25050/268772/Evidence-for-social-tr… Abstract: In mammals, social transmission of information from mother to offspring can help young to develop specialised and complex foraging behaviours. Although this social transmission is well recognised in some marine mammals, no conclusive evidence has been reported for otariids (fur seals and sea lions). Here, using animal-borne video and movement data from an adult female Australian sea lion, we provide evidence for mother-to-pup social transmission of foraging behaviour. Social transmission of foraging behaviour may be a component of development in Australian sea lions, whereby prolonged maternal care (~18 months) could provide mothers the opportunity to demonstrate foraging behaviours to pups. Don't hesitate to get in contact if you have any questions.

New Publication: Short consolidated satellite tag for blubber implantation on right whales
by Alexandre Zerbini 09 Feb '26

09 Feb '26

Dear all, On behalf of my co-authors, I am pleased to share a new publication on the development of a short, consolidated satellite tag for implantation in the blubber of right whales. This tag is also an option for smaller baleen whale species such as minke, sei and Bryde's whales. Zerbini, A. N., S. Fernández, S. Fermepin, et al. 2026. Development of a Short, Integrated, Consolidated Satellite Tag Designed to Anchor in the Blubber of Right Whales (*Eubalaena* spp.). Marine Mammal Science 42, no. 2: e70130. https://doi.org/10.1111/mms.70130. Abstract: Right whales (genus *Eubalaena*) are among the most endangered baleen whales in the world. Investigating their spatial ecology and movement patterns is essential to assess their vulnerability to anthropogenic threats and to promote management and conservation. Satellite tagging has been established as a powerful tool to understand cetacean habitat use, but invasive tag configurations have raised concerns about the potential for health impact on tagged individuals, especially for endangered species. In this study, the development and application of new fully integrated, consolidated tags designed to anchor in the blubber of right whales is described. SPOT-177S (n = 29) and SPOT-396 (n = 9) tag designs were deployed in southern right whales (*Eubalaena australis*) in Argentina. Tag duration ranged from approximately 11–50 days (average = 24 days). No statistical differences in transmission duration were found across sex, demographic category (mothers with calves and solitary animals), year, and tag design. In addition, the use of a polydopamine antimicrobial coating did not contribute significantly to improving tag duration. These shorter, right whale “blubber-only” tags fill a gap between percutaneous instruments with external electronics and those that are fully implanted but anchor below the blubber-muscle interface. Therefore, they represent a less invasive tool for research questions on right whale movements and habitat use that can be answered with transmission durations of 2–7 weeks. These new instruments may also be applicable as a subfascial design for smaller baleen whale species with relatively thin blubber layers. The paper is available here: https://doi.org/10.1111/mms.70130 If you want the pdf, please send me an email at the address below. Best wishes, Alex Zerbini -- Alexandre N.

New publication: Beaked whale dive behavior and acoustic detection range off Louisiana using three-dimensional acoustic tracking
by Frouin-Mouy, Heloise 07 Feb '26

07 Feb '26

Dear colleagues, My co-authors and I are pleased to share our recent publication: Beaked whale dive behavior and acoustic detection range off Louisiana using three-dimensional acoustic tracking. Please find our open access article at: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0340398 Frouin-Mouy H, Frasier KE, Hildebrand JA, Snyder ER, Wiggins SM, et al. (2026) Beaked whale dive behavior and acoustic detection range off Louisiana using three-dimensional acoustic tracking. PLOS ONE 21(2): e0340398. https://doi.org/10.1371/journal.pone.0340398 Abstract: Understanding abundance and trends of beaked whales in the heavily industrialized Gulf of America (formerly Gulf of Mexico), is critical for management but challenging with visual-based distance-sampling due to their elusive surface behavior. Acoustic-based distance-sampling methods rely on accurate modeling of detection probability as a function of distance from a recorder, requiring population-specific diving and acoustic behavior parameters, which is currently lacking for Gulf populations. To address this, we used passive acoustic tracking with two 4-channel High-Frequency Acoustic Recording Packages (HARPs) deployed off Louisiana (~1100 m depth) in 2021. Echolocation clicks detected on both recorders were localized in 3D to characterize acoustic and diving behavior. These data informed a Monte Carlo cue-based simulation to estimate the probability of detection by a near-seafloor single-sensor HARP. A trial-based approach also estimated detection probability as a function of range to a single-channel sensor deployed at the site. Results show species-specific differences. Goose-beaked whales (Ziphius cavirostris), were detected for longer periods during foraging dives (n = 24 dives, mean: 20.5 min; range: 7–42) compared with Blainville’s (Mesoplodon densirostris, n = 2 dives, 13.6 min; 11–16) and Gervais’ (Mesoplodon europaeus, n = 24 dives, 12.7 min; 7–19) beaked whales. Maximum dive depths also differed, with some goose-beaked whales foraging at or near the seafloor. Descent and ascent rates were similar within species but differed among them (1.34/1.40 m/s for goose-beaked and 1.15/1.19 m/s for Gervais’ beaked whales). Source level and broadband directivity index were estimated at 225 dBpp re 1 μPa-1m and 26 dB for goose-beaked whales, and 218 dBpp re 1 μPa-1m and 20 dB for Gervais’ beaked whales. Estimates were not possible for Blainville’s beaked whales due to limited data. In both the Monte Carlo simulation and trial-based approach, detection probability declined sharply with ranges, reflecting the highly directional beam of beaked whale echolocation clicks. Please feel free to reach out if you have any questions. Best regards, Heloise Heloise Frouin-Mouy, PhD

New publication - seal diet and competition
by Izzy Langley 06 Feb '26

06 Feb '26

Dear colleagues, My co-authors and I are pleased to share our new article looking at competition between grey and harbour seals in Scotland through temporal changes in their dietary niche. Langley, I., Hammond, P. S., Thompson, P. M., Pierce, G. J., Wilson, L. J., Hall, A. J., Hastie, G., D., & Russell, D. J. F. (2026). Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines. Oikos, e11875. https://doi.org/10.1002/oik.11875 Abstract: Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina vitulina in some areas have declined, and competition with stable/increasing numbers of grey seals Halichoerus grypus is a potential factor. Here, we standardised disparate seal diet datasets (based on analysis of prey hard parts in faeces) to investigate summer dietary metrics in two regions spanning a 24-year period. We estimated dietary niche breadth (Simpson's diversity, D) modelled as a function of sample size, proportional biomass diet composition corrected for digestion, and interspecific dietary niche overlap (Pianka index, O). Dietary niche overlap was high across time and space (O >0.7). In the Moray Firth, the harbour seal dietary niche was narrow when the population was high and stable (1987–1995, mean ± SE, D = 2.9 ± 0.3) but was significantly broader when the population depleted (2010, D = 7.2 ± 0.5). Prey composition shifted from energy-rich sandeels and clupeids to a more diverse diet of gadids and flatfish. Conversely, the dietary niche of the stable/increasing grey seal population was consistently narrow, dominated by sandeels (e.g. 2010, D = 2.3 ± 0.4). In southeast Scotland, where grey seal numbers were stable and harbour seals declined, there was no trend in the dietary niche of either species, though sandeels were less prevalent in later years. We propose that grey seals outcompeted harbour seals in the Moray Firth, and that the availability of sandeels to both seal species decreased in southeast Scotland. Changes in prey availability have therefore likely been a factor in regional harbour seal declines and could be preventing recovery. https://nsojournals.onlinelibrary.wiley.com/doi/10.1002/oik.11875 Cheers, Izzy ---------------------------------------------------- Dr Izzy Langley Sea Mammal Research Unit (SMRU) Scottish Oceans Institute University of St Andrews St Andrews, Fife, KY16 8LB Pronouns: She/her Social media: @izzylangley.bsky.social @LangleyIzzy For information about grey seal predation, see our project webpage here<https://www.smru.st-andrews.ac.uk/sealpred/index.html> or email SMRUsealreports(a)st-andrews.ac.uk<mailto:SMRUsealreports@st-andrews.ac.uk> The University of St Andrews is a charity registered in Scotland: No SC013532
