Ship strikes of fin whales in the north-east atlantic: identifying hotspots and simulating mitigation measuresNARA Subscribed
Large whales are likely the marine megafauna most at risk from vessel collisions. However, studies often identify areas of greatest risk by calculating two-dimensional overlap metrics, overlooking vertical overlap in the three-dimensional water column. This study quantifies collision risk for fin whales in the north-east Atlantic by including dynamic parameters in collision risk models and simulates potential mitigation measur...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Rorquals and sperm whales are top predators of complex open ocean food webs and, although mesopelagic fish and cephalopods are predated upon by these cetaceans, the contribution of these prey groups to the whales' diet is not fully understood. Here, we aimed to better describe the consumption of mesopelagic prey by identifying targeted species at mid‐latitudes. We analyzed the prey availability and predator preferences by comp...
Decoding the complexities of transitions in football: a comprehensive narrative reviewNARA Subscribed
Background Transitions in football are pivotal moments in the game, carrying significant tactical and strategic implications. Despite the lack of a consensus on the exact definition and duration of transitions, their importance is evident in the analysis of football matches. Clear connections exist between performance indicators, team play styles, and specific game moments. The evolution of game analysis, facilitated by techno...
Introduction The oceanic waters around the Azores host a high diversity of cetaceans, with 28 species of toothed and baleen whales present year-round or seasonally. This high cetacean biodiversity likely plays an important role in the structure, functioning and productivity of the ecosystem, and may increase trophic redundancy, thus contributing to food web resilience to disturbances. Methods Here we used stable isotope ( δ 13...
Exposure to whale watching vessels affects dive ascents and resting behavior in sperm whalesOA Marine
Disturbance from whale watching can induce a wide range of behavioral responses in cetaceans, some of which can affect their energetic balance and, ultimately, their long-term fitness. However, assessing disturbance effects on deep-diving cetaceans remains challenging, as the majority of their activities occurs underwater and are difficult to monitor from surface observations. To surpass this limitation, we attached high-resol...
Efficient use of the energy budget is of fundamental importance for long-distance migrants, which must cope with seasonal energy demands and environmental conditions. Time-activity budgets can provide information on how animals balance energy use and acquisition over their annual cycle, and on the costs and benefits of different migratory strategies. Baleen whales, such as the fin whale, perform long migrations between feeding...
Global warming is affecting the population dynamics and trophic interactions across a wide range of ecosystems and habitats. Translating these real‐time effects into their long‐term consequences remains a challenge. The rapid and extreme warming period that occurred after the Last Glacial Maximum (LGM) during the Pleistocene–Holocene transition (7–12 thousand years ago) provides an opportunity to gain insights into the long‐te...
Aim Habitat diversity has been linked to the diversity and structure of island communities, however, little is known about patterns and processes within habitats. Here we aim to determine the contributions of habitat type and inferred dispersal frequency to the differences in taxonomic structure between assemblages in the same island habitat. Location The Macaronesian archipelagos (Azores, Madeira, the Canary Islands and Cabo...
