Projected changes to the extent and seasonality of seabird habitat in the California current and implications for marine spatial planning Open
Climate-induced changes in ocean conditions are likely to affect species habitat use across current management boundaries (e.g., marine protected areas). Therefore, it is important to identify potential future risks that may reduce the eff…

Assessing total mortality following seabird wrecks given variable data quantity and quality: the Cassin’s auklet die-off Open
Mass mortality events (MMEs) of seabirds are becoming more frequent as the global climate warms. Often documented via beached bird surveys, methods for estimating event-wide mortality are needed that can accommodate regional differences in…

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…

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…

Integrating remote sensing methods during controlled exposure experiments to quantify group responses of dolphins to navy sonar Open
Human noise can be harmful to sound-centric marine mammals. Significant research has focused on characterizing behavioral responses of protected cetacean species to navy mid-frequency active sonar (MFAS). Controlled exposure experiments (C…

Sympatry and resource partitioning between the largest krill consumers around the Antarctic Peninsula Open
Understanding how closely related, sympatric species distribute themselves relative to their environment is critical to understanding ecosystem structure and function and predicting effects of environmental variation. The Antarctic Peninsu…

Environmental factors influencing eastern North Pacific gray whale calf production 1994–2016 Open
This paper describes the relationship between eastern North Pacific gray whale calf production and environmental conditions in the Pacific Arctic where they feed. The results show how interannual variation in sea ice cover in the Bering an…

Movements, diving behaviour and diet of type‐C killer whales (<span><i>Orcinus orca</i></span>) in the Ross Sea, Antarctica Open
The fish‐eating, type‐C ecotype, killer whale is a top predator in the Ross Sea, Antarctica. Increasing knowledge of this animal's foraging habitats, diet and movement patterns is listed amongst the research priorities adopted under the fr…
View article: Skin in the game: Epidermal molt as a driver of long‐distance migration in whales
Skin in the game: Epidermal molt as a driver of long‐distance migration in whales Open
Long‐distance migration in whales has historically been described as an annual, round‐trip movement between high‐latitude, summer feeding grounds, and low‐latitude, winter breeding areas, but there is no consensus about why whales travel t…

Behavioral responses of satellite tracked Blainville's beaked whales (<i>Mesoplodon densirostris</i>) to mid‐frequency active sonar Open
The vulnerability of beaked whales (Family: Ziphiidae) to intense sound exposure has led to interest in their behavioral responses to mid‐frequency active sonar (MFAS, 3–8 kHz). Here we present satellite‐transmitting tag movement and dive …

Massive Mortality of a Planktivorous Seabird in Response to a Marine Heatwave Open
Climate change has exacerbated the occurrence of large‐scale sea surface temperature anomalies, or marine heatwaves (MHWs)—extreme phenomena often associated with mass mortality events of marine organisms. Using a combination of citizen sc…

Physiological, morphological, and ecological tradeoffs influence vertical habitat use of deep-diving toothed-whales in the Bahamas Open
Dive capacity among toothed whales (suborder: Odontoceti) has been shown to generally increase with body mass in a relationship closely linked to the allometric scaling of metabolic rates. However, two odontocete species tagged in this stu…

Use of time‐at‐temperature data to describe dive behavior in five species of sympatric deep‐diving toothed whales Open
This paper develops and validates a method of using time‐at‐temperature ( TAT ) histograms from satellite transmitter tags to describe the dive activity patterns and approximate depth distributions of five deep‐diving toothed whale species…
