Ecosystems We Study: Alaska Bioregions and Arctic
Alaska is simultaneously a landscape of extremes requiring specialized adaptations by plants and animals to survive the winters and a landscape of abundance that supports breeding birds each summer from as far away as Africa. Terrestrial Alaska also supports iconic species such as caribou and muskoxen whose population dynamics, predator/prey relationships and habitat ecology are researched by USGS scientists. Alaska is also bounded by 3 oceans and has a strong marine connection. USGS scientists conduct research that informs the management and conservation ecosystems that supports species such as sea ducks, seabirds, walrus, and polar bears.

Dynamic selection for forage quality and quantity in response to phenology and insects in an Arctic ungulate
Storm-scale and seasonal dynamics of carbon export from a nested subarctic watershed underlain by permafrost
Response of forage plants to alteration of temperature and spring thaw date: Implications for geese in a warming Arctic
Alaska Landbird Conservation Plan
Diffusion modeling reveals effects of multiple release sites and human activity on a recolonizing apex predator
Sea otter population collapse in southwest Alaska: Assessing ecological covariates, consequences, and causal factors
Sea otter (Enhydra lutris) populations in southwest Alaska declined substantially between about 1990 and the most recent set of surveys in 2015. Here we report changes in the distribution and abundance of sea otters, and covarying patterns in reproduction, mortality, body size and condition, diet and foraging behavior, food availability, health profiles, and exposure to environmental contaminants
Willow drives changes in arthropod communities of northwestern Alaska: Ecological implications of shrub expansion
Spring phenology drives range shifts in a migratory Arctic ungulate with key implications for the future
Dynamic landscapes in northwestern North America structured populations of wolverines (Gulo gulo)
Metabarcoding of environmental samples suggest wide distribution of eelgrass (Zostera marina) pathogens in the north Pacific
U.S. Geological Survey Arctic ecosystem assessments
Ecosystem response persists after a prolonged marine heatwave
