Evaluating Differences in Household Subsistence Harvest Patterns between the Ambler Project and Non-Project Zones [PDF]
, 2016 Western Alaska is one of largest inhabited, roadless areas in North America and, indeed, the world. Access, via a new road that would transverse Gates of the Arctic National Park and Preserve (GAAR), to a mining district in a vast roadless section of ...

Oikos, EarlyView.Grasslands, by definition, are dominated by graminoids. Nevertheless, forbs also make up a substantial part of vascular plant diversity in grasslands and are important resources of mammalian herbivores. However, forb recruitment is constrained by successful dominant graminoids, limiting access to safe sites for germination.

State-dependent foraging by caribou with different nutritional requirements
Journal of Mammalogy, 2020 Foraging by animals is hypothesized to be state-dependent, that is, varying with physiological condition of individuals. State often is defined by energy reserves, but state also can reflect differences in nutritional requirements (e.g., for reproduction,

Social-ecological soundscapes: examining aircraft-harvester-caribou conflict in Arctic Alaska [PDF]
, 2017 Thesis (M.S.) University of Alaska Fairbanks, 2017As human development expands across the Arctic, it is crucial to carefully assess the impacts to remote natural ecosystems and to indigenous communities that rely on wild resources for nutritional and ...

Impacts of reindeer grazing on phosphorus sorption and nutrient availability in a tundra site
Oikos, EarlyView.Reindeer Rangifer tarandus, a large circumpolar herbivore, can influence whether nitrogen (N) or phosphorus (P) is the primary limiting nutrient in tundra plant communities. Specifically, findings from a site in northern Scandinavia suggest that under conditions where reindeer grazing stimulates inorganic N availability, grazing may drive ecosystems ...

Seasonal variation of leaf functional traits in sub‐Arctic plants
Oikos, EarlyView.Leaf functional traits are informative of plant fitness and functions in ecosystems. These functional traits and their variation across geographic extents are much studied but less is known about their temporal variation over a growing season. Here, we provide an analysis of the seasonal variation in six leaf functional traits of 11 sub‐Arctic vascular

Frontiers in Ecology and Evolution, 2020 Boreal caribou (Woodland Caribou, boreal population; Rangifer tarandus caribou) is a prominent mammal at the heart of a decades-long conflict between a growing resource sector and the associated risks to biodiversity.
