The combined effects of multiple stressors in an endangered, long‐lived species: Lessons learned and ways forward Open
Exploring solutions to expanding industrial activities and climate change requires assessments of the combined effects of multiple stressors on wildlife populations. We present a spatially explicit state‐space model for the health, surviva…

Revised taxonomy of eastern North Pacific killer whales ( <i>Orcinus orca</i> ): Bigg’s and resident ecotypes deserve species status Open
Killer whales ( Orcinus orca ) are currently recognized as a single ecologically and morphologically diverse, globally distributed species. Multiple morphotypes or ecotypes have been described, often associated with feeding specialization,…

Decreasing body size is associated with reduced calving probability in critically endangered North Atlantic right whales Open
Body size is key to many life-history processes, including reproduction. Across species, climate change and other stressors have caused reductions in the body size to which animals can grow, called asymptotic size, with consequences for de…

Morphology of nares associated with stereo-olfaction in baleen whales Open
The sensory mechanisms used by baleen whales (Mysticeti) for locating ephemeral, dense prey patches in vast marine habitats are poorly understood. Baleen whales have a functional olfactory system with paired rather than single blowholes (n…

Boom-bust cycles in gray whales associated with dynamic and changing Arctic conditions Open
Climate change is affecting a wide range of global systems, with polar ecosystems experiencing the most rapid change. Although climate impacts affect lower-trophic-level and short-lived species most directly, it is less clear how long-live…

Using individual-based bioenergetic models to predict the aggregate effects of disturbance on populations: A case study with beaked whales and Navy sonar Open
Anthropogenic activities can lead to changes in animal behavior. Predicting population consequences of these behavioral changes requires integrating short-term individual responses into models that forecast population dynamics across multi…

A deep learning approach to photo–identification demonstrates high performance on two dozen cetacean species Open
Researchers can investigate many aspects of animal ecology through noninvasive photo–identification. Photo–identification is becoming more efficient as matching individuals between photos is increasingly automated. However, the convolution…

Traditional summer habitat use by Southern Resident killer whales in the Salish Sea is linked to Fraser River Chinook salmon returns Open
Southern Resident killer whales (SRKW, Orcinus orca ) are a small, endangered population of fish‐eating killer whales that inhabit coastal and inland waters of the western United States and British Columbia. SRKW have been in decline since…

Shaped by Their Environment: Variation in Blue Whale Morphology across Three Productive Coastal Ecosystems Open
Synopsis Species ecology and life history patterns are often reflected in animal morphology. Blue whales are globally distributed, with distinct populations that feed in different productive coastal regions worldwide. Thus, they provide an…

Spatiotemporal Overlap of Baleen Whales and Krill Fisheries in the Western Antarctic Peninsula Region Open
In Antarctica, abundant consumers rely on Antarctic krill for food, but krill are also the subject of a commercial fishery. The fishery overlaps in time and space with the foraging areas of these consumers, thus potential competition betwe…

Detecting changes in dynamic social networks using multiply-labeled movement data Open
The social structure of an animal population can often influence movement and inform researchers on a species' behavioral tendencies. Animal social networks can be studied through movement data; however, modern sources of data can have ide…

Scaling of maneuvering performance in baleen whales: larger whales outperform expectations Open
Despite their enormous size, whales make their living as voracious predators. To catch their much smaller, more maneuverable prey, they have developed several unique locomotor strategies that require high energetic input, high mechanical p…
