Snowpack dynamics have a major influence on wildlife movement ecology and predator–prey interactions. Specific snow properties such as density, hardness, depth determine how much an animal sinks into the snowpack, which in turn drives both energetic cost of locomotion predation risk. Here, we quantified relationships between five field‐measured variables track sink depths for widely distributed predators (bobcats Lynx rufus , cougars Puma concolor coyotes Canis latrans wolves C. lupus )...
Commercial vessel traffic in the Bering Strait is increasing. The region is, however, remote from most forms of response to accidents or disasters. Indigenous cultures continue traditional practices, including hunting and fishing waters Chukchi Seas. Ecologically, home a spectacular abundance seabirds, marine mammals, productivity. confluence expanding maritime commerce, remoteness, vibrant cultures, extraordinary biological richness requires robust governance promote safety, cultural...
Poyang Lake is China's largest freshwater lake in summer and provides important habitat for an internationally significant assemblage of waterbirds winter. Human-caused alterations to this system threaten compromise the long-term viability these bird populations due role water driving suitability. Little known, however, about patch-scale selection strategies within Poyang. Consequently, there potential spatial incongruence between protected area boundaries key habitats given system's high...
In this paper, we present a spatially explicit dataset of monthly shipping intensity in the Pacific Arctic region from January 1, 2015 to December 31, 2020. We calculated based on Automatic Identification System (AIS) data, type GPS transmitter required by International Maritime Organization all ships over 300 gross tonnes an international voyage, cargo 500 tonnes, and passenger ships. used AIS data received exactEarth satellite constellation (64 satellites as 2020), ensuring spatial...
Extreme weather events are becoming more frequent, with poorly known consequences for wildlife. In December 2021, an atmospheric river brought record-shattering amounts of rain and snow to interior Alaska, creating conditions expected cause mass mortality in grazing ungulate populations that need access ground forage. We characterized snowpack following the storm used a 36-year monitoring dataset quantify impacts on caribou (Rangifer tarandus) their primary predator, wolves (Canis lupus)....
Recently available downscaled ocean climate models for the Bering Sea and Aleutian Arc offer opportunity to assess vulnerability upper trophic level consumers such as marine birds. We analyzed seasonal annual spatial projections from three two physical variables (seawater temperature sea ice) forage (large copepods, euphausiids, benthic infauna), comparing projected conditions a recent time period (2003-2012) future (2030-2039). focused analyses on core areas within globally significant...
Abstract Wildlife management often involves trade‐offs between protecting species and allowing human activities development. Ideally, these decisions are guided by scientific studies that quantify the impacts of proposed actions on environment. However, critical information to assess may be lacking, such as certainty in where will take place, which hinder a robust impact assessment. To address this issue, we present Development Impacts Analysis (DIA), employs Monte Carlo simulation modeling...
The Aleutian Archipelago and surrounding waters have enormous ecological, cultural, commercial significance. As one of the shortest routes between North American Asian ports, Pacific Great Circle Route, which crosses through Archipelago, is traveled by thousands large cargo ships tanker vessels every year. To reduce maritime risks enhance navigational safety, International Maritime Organization built upon earlier offshore routing efforts designating five Areas Be Avoided (ATBAs) in Islands...
Snowpack dynamics have a major influence on wildlife movement ecology and predator-prey interactions. Specific snow properties such as density, hardness, depth determine how much an animal sinks into the snowpack, which in turn drives both energetic cost of locomotion predation risk. Here, we quantified relationships between 15 field-measured variables track sink depths for widely distributed predators (bobcats [Lynx rufus], coyotes [Canis latrans], wolves [C. lupus]) sympatric ungulate prey...
