Consequences of culturally-driven ecological specialization: Killer whales and beyond
by Hal Whitehead 12 Jun '26

12 Jun '26

The following paper has just been published: Consequences of culturally-driven ecological specialization: Killer whales and beyond. by: Hal Whitehead and John K.B. Ford Journal of Theoretical Biology 456: 279-294 Abstract: Culturally-transmitted ecological specialization occurs in killer whales, as well as other species. We hypothesize that some of the remarkable demographic and ecological attributes of killer whales result from this process. We formalize and model (using agent-based stochastic models parametrized using killer whale life history) the cultural evolution of specialization by social groups, in which a narrowing of niche breadth is spread and maintained in a group through social learning. We compare the demographic and ecological results of cultural specialization to those of a similar model of specialization through natural selection. We found that specialization, through either the cultural or natural selection routes, is adaptive in the short term with specialization often increasing fitness. Generalization, in contrast, is rarely adaptive. The cultural evolution of specialization can lead to increased rates of group extirpation. Specialization has little effect on group size but tends to reduce population size and resource abundance. While the two specialization processes produce similar results, cultural specialization can be very much faster. The results are generally consistent with what we know of the formation and maintenance of specialist ecotypes in killer whales, and have implications for the persistence, nature and ecological effects of these apex predators.

New paper on cetaceans' summer abundance and distribution in Bulgarian Black Sea waters
by Dimitar Popov 06 Mar '26

06 Mar '26

Dear all, On behalf of me and my co-authors, I am happy to share our recently published new paper on cetaceans' summer abundance and distribution in Bulgarian Black Sea waters, available on the link: https://www.acta-zoologica-bulgarica.eu/2024/Suppl_20_21.pdf Abstract: /All three Black Sea cetacean species are nominated as endemic subspecies for the basin listed in the IUCN Red List of Endangered species: the Black Sea harbour porpoise (Phocoena phocoena relicta) and Black Sea bottlenose dolphin (Tursiops truncatus ponticus) as Endangered (EN), while the Black Sea common dolphin (Delphinus delphis ponticus) as Vulnerable (VU). In addition, all three species are protected at national and international levels. Effective conservation of protected and endangered species requires robust data on their distribution to delineate important habitats. We present data on the summer distribution of cetaceans in Bulgarian shelf waters, derived from a series of vessel line transect distance sampling surveys, conducted in the summer months during the period 2020-2023. Harbour porpoise density estimates ranged from 0.156 ind./sq. km (CV=43%) in territorial waters in 2020 to 2.83 ind./sq. km (CV=27%) in deeper waters in 2022. Bottlenose dolphin density estimates ranged from 0.226 ind./sq. km (CV=49%) in territorial waters in 2023 to 0.542 ind./sq. km (CV=35%) in 2020, also in territorial waters. Common dolphin density ranged from 0.032 ind./sq. km (CV=80%) in territorial waters in 2023 to 0.699 ind./sq. km (CV=41%) in deep shelf waters in 2022. The distribution of porpoises has shown a clear preference for deep waters (80-100 m), indicating a shift from the coastal waters that are their preferred habitat in the spring. The density of common dolphin has also shown a gradient towards deeper waters of the shelf, while bottlenose dolphins show a preference for coastal waters. Here, we propose updated threshold values of Descriptor 1's criteria 2 and 4 of the EU Marine Strategy Framework Directive and identify important habitats for harbour porpoises and bottlenose dolphins that remain outside of NATURA 2000's scope./ In case you have any queries, do not hesitate to contact me.

Re: [MARMAM] New publication on stomach contents of stranded Ziphius cavirostris in the eastern Mediterranean
by Arda M. Tonay 26 Dec '25

26 Dec '25

Dear All, Apologies for cross posting. We would like to inform you that the new paper on "Stomach Contents of Stranded Goose-Beaked Whales in the Levantine Basin and Aegean Sea" has been published in Marine Mammal Science. Tonay, A.M., Salman, A., Taşkaya, İ., Danyer, E., Dede, A., Çanakcı, T., Amaha Öztürk, A. 2025. Stomach contents of stranded goose-beaked whales in the Levantine Basin and Aegean Sea. Marine Mammal Science 0:e70075. You can view the article at: https://doi.org/10.1111/mms.70075 Abstract Goose-beaked whale (Ziphius cavirostris), a cosmopolitan odontocete, is commonly found in the Mediterranean Sea. This study, the first to examine the stomach contents of the goose-beaked whale in the Aegean Sea and Levantine Basin, reveals key aspects of its diet. The stomach contents of one whale from Seferihisar, Türkiye, in 2016, and five from a mass stranding on Cyprus in February 2023 were analyzed. A total of 1,448 lower beaks from 16 cephalopod species were identified, with six species-Octopoteuthis sicula, Ancistrocheirus lesueurii, Histioteuthis reversa, Chtenopteryx sicula, Chiroteuthis veranii, and Todarodes sagittatus-comprising the primary diet. Four species-Loligo forbesii, Pyroteuthis margaritifera, Pterygioteuthis giardi, and Brachioteuthis riisei-were recorded for the first time in goose-beaked whale stomachs. Their prey preference is generally pelagic cephalopods, though benthic or demersal species are occasionally eaten. The high species diversity and the presence of species not found in other studies may be due to differences in cephalopod fauna characterized by seabed and other oceanographic features of the eastern Mediterranean. The Mediterranean population is genetically divided into western and eastern subpopulations, and their diets appear to differ.

New article on nutrient concentrations in minke whale faeces
by Brandt, Carla Freitas 18 Dec '25

18 Dec '25

Dear Colleagues, On behalf of my co-authors I am pleased to present our recently published paper: Freitas, C., Gundersen, K., Lindblom, L., Biuw, M., Haug, T., 2023. Nutrient concentrations in minke whale faeces and the potential impact on dissolved nutrient pools off Svalbard, Norway. Progress in Oceanography, 210, 102927. Abstract: There is increasing interest in assessing the impact of whales on nutrient and carbon cycling in the ocean. By fertilising surface waters with nutrient-rich faeces, whales may stimulate primary production and thus carbon uptake, but robust assessments of such effects are lacking. Based on the analysis of faeces collected from minke whales (n = 31) off Svalbard, Norway, this study quantified the concentration of macro and micronutrients in whale faeces prior to their release in seawater. Concentrations of the macronutrients nitrogen (N) and phosphorous (P) in minke whale faeces were 50.1 ± 10.3 and 70.9 ± 12.1 g kg−1 dry weight, respectively, while the most important micronutrients were zinc (Zn), iron (Fe), manganese (Mn) and copper (Cu). By combining measured faecal nutrient concentrations with estimated prey-consumption and prey-assimilation rates, we calculate that the current population of approximately 15, 000 individuals in the small management area (SMA) of Svalbard defecates daily 7 ± 1.4 tonnes (t) N and 10 ± 1.7 t P during summer. The molar ratio of N:P in minke whale faeces was 1.6:1, meaning that N was proportionally limiting, when compared to average elemental ratios of 16:1 in phytoplankton. In case of no N limitation in surface waters at that time, the release of elemental P through defecation in surface waters has the potential to stimulate 407 ± 70 t of carbon per day during summer as new or regenerated primary production in the SMA of Svalbard. This amounts to 0.2 to 4 % of daily net primary production in this region. This study provides the first assessment of nutrient concentration in whale faeces prior to their dissolution in sea water. Further research, namely on the amount of N released via urine and seasonal changes in excreted nutrients, is needed to better assess the full potential of whale nutrient additions to dissolved nutrient pools in surface waters at regional and global scales.

New publication: The times they are a changin’: Temporal patterns in small cetacean abundance in the northeast Atlantic
by Oriol Giralt 30 Nov '25

30 Nov '25

Dear colleagues, In behalf of my coauthors, I am glad to share with you the publication “The times they are a changin’: Temporal patterns in small cetacean abundance in the northeast Atlantic”. Authors: Oriol Giralt Paradell, Ashley Bennison, Meike Scheidat, Mick Mackey, Helder Araújo, Steve C.V. Geelhoed, Dimitar Popov, Patricia Breen, Mark Jessopp, Ana Cañadas and Emer Rogan Abstract: Conserving marine species effectively requires spatially and temporally explicit knowledge of their abundance and distribution for assessing potential impacts (e.g., from fishery bycatch, anthropogenic sound, ship strikes) over different spatial and temporal scales. We used aerial surveys and distance sampling to estimate abundance of seven frequently encountered small cetacean species in the northeast Atlantic and examine seasonal and interannual variations. Five surveys were carried out over the Irish EEZ in summer 2016, 2021 and 2022 and winter 2016–2017 and 2022–2023. Seasonal and annual variations in abundance were seen across species. Harbour porpoise showed a steady decrease in abundance, with estimates ranging from 38,260 (CV: 23.7) individuals in summer 2016 to 6,604 (CV: 40.8) in winter 2022–2023. Similarly, bottlenose dolphin numbers ranged from an unprecedented 212,646 (CV: 15.5) individuals in the winter of 2016–2017 to 11,328 (CV: 42.4) in summer 2021. In contrast, common dolphins increased from 13,192 (CV: 75.2) individuals in winter 2016–2017 to 594,293 (CV: 28.2) in summer 2021. Other species, such as Risso’s, Atlantic white-sided, white- beaked and striped dolphins were seen more sporadically and in lower numbers. The recent decline in harbour porpoise abundance is concerning and merits further investigation. Results provide the first measure of seasonal and interannual variability in abundance, possibly reflecting large scale movement patterns and population change and allow for the seasonal assessment of potential anthropogenic impacts.
