High Priority Species for Avian Influenza in Alaska

In early 2006, an Alaska Interagency Avian Influenza Working Group was formed to develop a ranking matrix for selecting priority species to be sampled within Alaska. Most wild bird species with populations that utilize areas of both Alaska and Asia were identified and considered in the ranking exercise. Based on scoring criteria, 28 target species were chosen for sampling. Alaska is a...

Ecosystem Shifts in Arctic Seas

In addition to the direct effects of sea ice loss on walrus (Odobenus rosmarus divergens) and polar bears (Ursus maritimus) that use ice as a platform, the decline of Arctic sea ice is predicted to promote a fundamental ecosystem shift from benthic animals that forage on the sea floor to pelagic animals that forage near the sea surface.

Forecasting community reassembly using climate-linked spatio-temporal ecosystem models

Ecosystems are increasingly impacted by human activities, altering linkages among physical and biological components. Spatial community reassembly occurs when these human impacts modify the spatial overlap between system components, and there is need for practical tools to forecast spatial community reassembly at landscape scales using monitoring...

Native American fire management at an ancient wildland–urban interface in the Southwest United States

The intersection of expanding human development and wildland landscapes—the “wildland–urban interface” or WUI—is one of the most vexing contexts for fire management because it involves complex interacting systems of people and nature. Here, we document the dynamism and stability of an ancient WUI that was apparently sustainable for more than 500 y...

Predictors of invertebrate biomass and rate of advancement of invertebrate phenology across eight sites in the North American Arctic

Average annual temperatures in the Arctic increased by 2–3 °C during the second half of the twentieth century. Because shorebirds initiate northward migration to Arctic nesting sites based on cues at distant wintering grounds, climate-driven changes in the phenology of Arctic invertebrates may lead to a mismatch between the nutritional...

Geochemistry of coastal permafrost and erosion-driven organic matter fluxes to the Beaufort Sea near Drew Point, Alaska

Accelerating erosion of the Alaska Beaufort Sea coast is increasing inputs of organic matter from land to the Arctic Ocean, and improved estimates of organic matter stocks in eroding coastal permafrost are needed to assess their mobilization rates under contemporary conditions. We collected three permafrost cores (4.5–7.5 m long) along a...

Coding-Complete Genome Sequence of Avian Orthoavulavirus 16, isolated from Emperor Goose (Anser canagica) feces, Alaska, USA

We sequenced the coding-complete genome of an avian orthoavulavirus serotype 16 (AOAV-16) isolate recovered from emperor goose (Anser canagicus) feces collected in Alaska. The detection of AOAV-16 in North America and genomic sequencing of the resultant isolate confirms that the geographic distribution of this virus extends beyond Asia.

Aquatic Ecosystem Vulnerability to Fire and Climate Change

Fire is the dominant ecological disturbance process in boreal forests (coniferous forests consisting mostly of pines, spruces, and larches) and fire frequency, size and severity are increasing in Alaska owing to climate warming. However, interactions among fire, climate, permafrost, vegetation and hydrologic and watershed processes are poorly understood, yet critical for
