Mechanistic Species Distribution Modelling: Ecological Niche Modelling with NicheMapR
by Oliver Hooker 09 Mar '26

09 Mar '26

Develop advanced habitat and distribution modelling skills for marine mammal research in our live online course *Mechanistic Species Distribution Modelling: Ecological Niche Modelling with NicheMapR (MSDM01)*. Understanding how marine mammals respond to environmental conditions is central to predicting habitat use, distribution shifts, and responses to climate change. *Mechanistic species distribution models (SDMs)* provide a powerful framework for linking environmental drivers with physiological and energetic constraints that shape where species can survive and thrive. This course introduces the theory and practical implementation of mechanistic ecological niche modelling using *R and the NicheMapR package*, allowing researchers to move beyond purely correlative models and incorporate biological processes into distribution predictions. These methods are highly relevant for marine mammal research, including: - Predicting habitat suitability under changing conditions - Linking physiology and energetics to environmental drivers - Forecasting distribution shifts under climate change scenarios - Integrating environmental variables with movement and survey data - Supporting conservation planning and marine spatial management *The course covers:* - Foundations of ecological niche theory and mechanistic SDMs - Differences between mechanistic and correlative modelling approaches - Incorporating physiology, energetics, and environmental constraints into models - Using *NicheMapR* to simulate organism–environment interactions - Building mechanistic niche models and interpreting outputs - Applications to climate change and conservation decision-making Participants will work through practical examples and learn how to construct mechanistic models that can be applied to real ecological datasets within reproducible R workflows. Delivered live online, the course offers direct interaction with the instructor, opportunities to discuss your own datasets, and structured guidance through applied modelling examples. All participants receive course materials, example code, and post-course support. *Course details* Dates: 7 April 2026 Duration: 1 days (approximately 4.5 hours per day) Format: Live online Fee: £150 This course is suitable for postgraduate students, researchers, and professionals working in *marine mammal ecology, conservation, and spatial modelling* who want to develop mechanistic approaches for predicting species distributions.

New publication: sperm whale hotspots with multiscale Bayesian Additive Regression Trees framework (Cynthia Barile)
by Cynthia BARILE 09 Mar '26

09 Mar '26

Dear MARMAM community, I am delighted to share our recent publication: 'Sperm whale hotspots off western Ireland and the importance of dynamic variables as shown by a multiscale Bayesian additive regression trees workflow' in Frontiers in Marine Science. We used data collected off western Ireland with towed hydrophone arrays (under the ObSERVE-Acoustic project) to apply a state-of-the-art Bayesian modelling framework (Bayesian Additive Regression Trees, aka BART) to predict sperm whale probability of occurrence and habitat favourability. We included a data-driven process to select the most appropriate spatiotemporal scales for a set of both static and dynamic variables of interest. We hope those findings will serve as evidence for conservation and management strategies as well as a solid baseline for future assessments. You can read the full paper here: https://doi.org/10.3389/fmars.2026.1767540 We will be presenting this research as a poster at the ECS in Dundee next month, feel free to come for a chat! Enjoy the read! With our best wishes, Cynthia Barile, Simon Berrow, Jonathan Gordon, Rossa Meade, Morgane Pommier, Joanne O'Brien.

New Publication: First Report on the Acoustic Signals of Lahille’s Bottlenose Dolphins in Argentina
by Gisela Giardino 08 Mar '26

08 Mar '26

Dear MARMAM community, My co-authors and I are pleased to share our recent publication in the journal *Animals*: *"First Report on the Acoustic Signals of Lahille’s Bottlenose Dolphins (Tursiops gephyreus) in Argentina"*. Abstract: This study provides the first characterization of the acoustic signals emitted by Lahille’s bottlenose dolphins (Tursiops gephyreus) in Argentine waters, establishing a baseline for the species’ southern distribution limit. Passive acoustic monitoring was conducted in the inner channels of the Bahía Blanca Estuary using a broadband hydrophone and F-POD detectors. We documented a diverse acoustic repertoire consisting of echolocation clicks, whistles, bray-calls, and chirps. Acoustic presence was predominantly diurnal and showed a marked synchronization with the tidal cycle, with peak activity occurring during the ebbing tide. Whistles had a mean center frequency of 8.1 kHz, showing spectral overlap with other regional populations in the Southwestern Atlantic. Echolocation clicks were broadband, with peak frequencies ranging from 18 to 127 kHz and a mode around 40 kHz. These results suggest that dolphin movement in the estuary’s internal channels is structured by hydrodynamics, likely reflecting foraging opportunities associated with tidal flow. Given the endangered status of this species, these data establish a technical framework for non-invasive monitoring and habitat-use assessments in complex estuarine environments.

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.

New paper: Inuit hunt as a platform for observing narwhals in Inglefield Bredning, Greenland
by Evgeniy Podolskiy 04 Mar '26

04 Mar '26

Dear MARMAM community, We are pleased to share our recent open-access publication based on collaboration with Inuit hunters and drone footage: Ogawa, M., Podolskiy, E.A. Inuit hunt as a platform for observing narwhals (Monodon monoceros) in Inglefield Bredning (Kangerlussuaq), Greenland. Polar Biol 49, 30 (2026), https://doi.org/10.1007/s00300-026-03470-5 ABSTRACT Direct observations of narwhals are scarce but needed for understanding this ecologically and culturally important species. Here, we describe the first boat-based observations of narwhals in their key summering ground in Greenland (Inglefield Bredning), collected during an Inuit hunt and enhanced by drone air support. During 3–8 August 2024, 83 encounters and 506 narwhal observations were made from a semi-stationary boat at the head of the fjord, of which 58 were filmed with a drone. Boat observations near the north side of the fjord indicated that narwhals preferentially traveled outward to the west, with a clear link to currents. The presence of narwhals was more likely in the afternoon but was highly intermittent, with intervals between encounters reaching as much as 15–28 h, highlighting the patience needed to observe and catch a narwhal. We also recorded a motionless sleep-like behavior at the surface, known as pugginnartoq (Greenlandic) for narwhals. Aerial drone support was useful for revealing unseen-from-sea-surface features and behaviors, which we describe as potentially interesting for future investigation. For example, drone imagery revealed that 71 ± 7% of narwhals had tusks, with a mean tusk-to-body-length ratio of 0.23 ± 0.01. Overall, this report shows that hunting expeditions integrated with scientific methods provide important insights and inspire further work. Best regards, Evgeny Podolskiy, Assoc. Prof. Arctic Research Center, Hokkaido University
