BNZ LTER Web Site Map


The Bonanza Creek Long Term Ecological Research
We are located in the boreal forest of interior Alaska, USA and our facilities are centered in the city of Fairbanks. Research at our LTER site focuses on improving our understanding of the long-term consequences of changing climate and disturbance regimes in the Alaskan boreal forest. Our overall objective is to document the major controls over forest dynamics, biogeochemistry, and disturbance and their interactions in the face of a changing climate. The site was established in Fairbanks, Alaska in 1987 as part of the National Science Foundation's Long Term Ecological Research (LTER) Program.

May 16, 2013 Thesis Defense
    Snowshoe hare (Lepus americanus) survival depends on the interaction of habitat characteristics with numerous biological and environmental variables. In boreal regions where considerable habitat heterogeneity exists, hares balance food availability with predation risk by moving among habitats seasonally, but it is largely unknown how often they do so at shorter time scales. I investigated the seasonal effects of habitat, weather, and individual hare characteristics on survival and movement in two common but fundamentally different boreal habitats. Higher survival was associated with summer months, better body condition, and black spruce rather than early successional forest. Hares moved among habitats at least once per day on average, typically at night when movement rates were highest. Seasonal home ranges often contained core use areas in different habitats. Hares used more open areas at night, presumably when feeding on preferred browse, and typically spent daylight hours under dense cover. Behavior of individuals varied greatly with some hares repeatedly moving up to 1 km between defined patches over short time periods and others remaining roughly within a 1 ha area. These findings illustrate the complexity of snowshoe hare ecology in an area where habitat variation promotes high movement rates over small temporal and spatial scales.
