Booms Institution: University of Alaska Fairbanks EPA Grant Representative: Theodore J. Just Project Period: September 1, 2005 - August 30, 2008 Project Amount: $102,724 RFA: STAR Graduate Fellowships Research Category: Academic Fellowships Description Objective: Birds are valuable bioindicators of system health and are useful in assessing contaminated environments. I plan to collect blood, feather, and addled egg samples from gyrfalcons (Falco rusticolus) and rough-legged hawks (Buteo lagopus) nesting various distances from a known, but little studied source of contamination in Western Alaska, the Cape Romanzof Long Range Radar Site. This will help the Yukon Delta National Wildlife Refuge (YDNWR) determine if contaminants represent a threat to these nesting populations. Also, using these species as indicators of contaminant levels and contaminant distribution in the environment surrounding the military instillation will illuminate potential contaminant risks indigenous subsistence hunters and fishers that use this area extensively face. Our primary hypotheses are: There is no correlation between contaminant levels in raptor nests and distance from the radar site. There is no significant difference in contaminant levels among three geographically distinct study sites on the YDNWR. There is no significant difference in contaminant levels between rough-legged hawks and gyrfalcons nesting in the YDNWR. Contaminants in YDNWR raptors are not above levels documented to reduce productivity. Given previous contaminants testing of the soil, water, vegetation, and a few animals very close to the site have yielded high levels of 39 contaminants, I expect birds nesting closest to the site will also have elevated contaminant levels. These levels should decline with distance from the site. I expect there will be a significant difference in contaminant levels among study sites and between species. Last, I expect contaminant levels are not above those that have been documented to reduce productivity.
