This dissertation presents results from four recently discovered archeological sites in southcentral Alaska. The sites range from the Younger Dryas to middle Holocene in age and provide valuable contextual information for the human process of colonizing a region that was heavily glaciated during the LGM. The deglaciation and human colonization of southcentral Alaska is one of the most significant aspects of the settling phase in eastern Beringia not only for its potential to inform about the human response to post-glacial landscapes but also for what we can learn about subsequent migrations to the southern coast of Alaska. Understanding how early foraging societies spread throughout eastern Beringia, after its initial...

In chapter 1, my objective was to describe life history patterns of goldeneyes in relation to other sea duck species, which are typically described as long-lived, with delayed maturity, low and variable annual breeding probability, and invariant adult female survival. I used multistate capture-mark recapture models (Arnason 1972, 1973) in Program MARK (White and Burnham 1999) to estimate multiple demographic parameters, and used several explanatory variables to investigate the effects of climate on breeding and wintering areas, nesting density (as indexed by nest box occupancy), and individual variation (e.g., body condition) on my demographic parameters of interest. I detected substantial annual variation in adult...

A Multi-scale Resilience-based Framework for Restoring and Conserving Great Basin Wet Meadows and Riparian Ecosystems
FY2016This project will develop a strategic approach for conservation of wet meadows and riparian ecosystems and the species they support that focuses on threats caused by natural and anthropogenic disturbance. It uses information on (1) the factors that affect wet meadow and riparian ecosystem resilience to both natural and human-caused disturbances at the scale of the watershed and meadow or riparian ecosystem, and (2) the distributions and population abundances of at risk species to determine focal areas for management. Maps of the relative resilience of watersheds and wet meadows are overlaid with data on at risk species and the predominant threats to facilitate this process. Decision matrices are developed...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
