Abstract Widespread changes in the distribution and abundance of plant functional types (PFTs) are occurring Arctic boreal ecosystems due to intensification disturbances, such as fire, climate-driven vegetation dynamics, tundra shrub expansion. To understand how these affect ecosystems, we need first quantify change for multiple PFTs across recent years. While landscape patches generally composed a mixture PFTs, most previous moderate resolution (30 m) remote sensing analyses have mapped...
The ability to quantify spatial patterns and detect change in terrestrial vegetation across large landscapes depends on linking ground-based measurements of remotely sensed data. Unlike non-overlapping categorical types (i.e., typical land cover maps), species-level gradients foliar are consistent with the ecological theories individualistic response species niche space. We collected data for vascular plant, bryophyte, lichen 17 environmental variables Arctic Coastal Plain Brooks Foothills...
Ixodes pacificus Cooley & Kohls is the primary vector of Lyme disease spirochetes to humans in western United States. Although not native Alaska, this tick species has recently been found on domestic animals state. a known range within contiguous States and southwest Canada; therefore, it clear if introduced individuals can successfully survive reproduce high-latitude climate Alaska. To identify areas suitable habitat Alaska for I. pacificus, we used model parameters from two existing sets...
St. Lawrence Island, in the northern Bering Sea, is an important biogeographic link between flora of northeastern Asia and northwestern North America. A vascular plant inventory was conducted on Island 1960s by Steven Young which 250 taxa were documented. Since that time, very few collections have been made island. We a survey to improve our understanding baseline floristics identify populations species conservation concern. Of 166 we collected late July 2012, number represent new or...
Abstract Foraging behaviors often involve trade‐offs between predation risk and access to forage. Risk‐forage may be particularly acute for maternal female ungulates, whose nutritional needs are high calves highly vulnerable predation. In moose, the selection of calving habitat is one way in which females can respond these trade‐offs. Our objective was compare among‐individual variation selected nonmaternal moose during season. We hypothesized that, compared females, would exhibit a greater...
