Data from: Variation in age ratio of midcontinent greater white-fronted geese during fall migration
- 负责人:
- DOI:
- doi:10.5061/dryad.28660
- 摘要:
- Alaska at a northern autumn staging area near Delta Junction, Alaska. Photographic sampling conducted near Delta Junction resulted in an annual age ratio
Data from: Non-linear effect of sea ice: Spectacled Eider survival declines at both extremes of the ice spectrum
- 负责人:
- DOI:
- doi:10.5061/dryad.s1c5m5k
- 摘要:
- in Alaska and Russia and winters in the Bering Sea, appears to be complex. While severe ice can impede foraging for benthic prey, ice also suppresses
Data from: Inferring the geographic origin of a range expansion: latitudinal and longitudinal coordinates inferred from genomic data in an ABC
- 负责人:
- DOI:
- doi:10.5061/dryad.4s1gg
- 摘要:
- collected in the Collared pika that underwent post-glacial expansion across Alaska, as well as present an assessment of its accuracy under a known model of expansion
Data from: Coexistence and origin of trophic ecotypes of pygmy whitefish, Prosopium coulterii, in southwestern Alaskan lake
- 负责人:
- DOI:
- doi:10.5061/dryad.7pd82
- 摘要:
- , and genetic structure of three putative forms of the pygmy whitefish, Prosopium coulterii, that were first reported from Chignik Lake, southwestern Alaska, over 40 yea
Data from: Contemporary ancestor? Adaptive divergence from standing genetic variation in Pacific marine threespine stickleback
- 负责人:
- DOI:
- doi:10.5061/dryad.450c2v7
- 摘要:
- stickleback from eight locations extending from Alaska to California, and phenotyped them for platedness and body shape. Pairwise FST varied from 0.02 to 0.18
Data from: Sex-dependent phenological plasticity in an arctic hibernator
- 负责人:
- DOI:
- doi:10.5061/dryad.47pf0
- 摘要:
- seasonal dormancy in response to extreme weather events is unclear. Here, we show that arctic ground squirrels in northern Alaska exhibited sex-dependent
Data from: Alaskan brown bears (Ursus arctos) aggregate and display fidelity to foraging neighborhoods while preying on Pacific salmon al
- 负责人:
- DOI:
- doi:10.5061/dryad.1h8sr94
- 摘要:
- x spawning streams for sockeye salmon, O. nerka, in southwestern Alaska. The streams were grouped into two trios on opposite sides of Lake Al
Data from: Climatic thresholds shape northern high-latitude fire regimes and imply vulnerability to future climate change
- 负责人:
- DOI:
- doi:10.5061/dryad.r217r
- 摘要:
- ndscape features (i.e. vegetation and topography) across Alaska. Boosted regression tree (BRT) models captured the spatial distribution of fire across boreal forest and tundra
Data from: Integrated population modeling provides the first empirical estimates of vital rates and abundance for polar bears in the Chukchi Sea
- 负责人:
- DOI:

- 摘要:
- densities west of Alaska were 0.0030 bears/km2 (95% CRI = 0.0016–0.0060), similar to 1980s-era density estimates although methodological differences
Data from: Migration strategy affects avian influenza dynamics in mallards (Anas platyrhynchos)

- 摘要:
- northern breeding grounds (Alaska and the NW Pacific Rim) into the wintering population, facilitating gene flow at continental scales, but circula
