Including Fitness and Health Proxies Can Alter Our Understanding of Habitat SelectionNARA Subscribed
Habitat selection analyses, which discern the environmental conditions individuals select, often inform conservation planning. Through a literature review, we demonstrate that recent habitat selection studies rarely include fitness and health information. With a simulation study, we show that ignoring such information could support the protection of sink habitats. Our case studies demonstrate how health and fitness proxies can...
Diets of sculpins ( Myoxocephalus spp.) and Arctic char ( Salvelinus alpinus ) during a spring resource pulse in the Canadian ArcticNARA Subscribed
The Arctic is one of the fastest‐warming marine regions in the world, which is changing the timing of seasonal sea‐ice dynamics. The annual summer breakup of sea‐ice coincides with resource pulses, which provide critical food sources for consumers to exploit. Marine organisms respond behaviourally to exploit these resources, with some migrating to presumably maximize feeding opportunities, whereas others remain resident, provi...
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...
Same-sex socio-sexual interactions among male narwhalNARA Subscribed
Same-sex socio-sexual behavior is seemingly ubiquitous across the animal kingdom. Although difficult to observe in wild cetaceans, aerial imagery using drones has drastically improved our ability to document such behaviors. In 2017, off northern Baffin Island, Canada, a group of eight adult male narwhals were recorded engaging in same-sex socio-sexual behavior. To describe and analyse the recorded behaviors, we developed an et...
The world’s largest extant fish, the whale shark Rhincodon typus , is one of the most-studied species of sharks globally. The discovery of predictable aggregation sites where these animals gather seasonally or are sighted year-round – most of which are coastal and juvenile-dominated – has allowed for a rapid expansion of research on this species. The most common method for studying whale sharks at these sites is photographic i...
