Creator:: Bruggeman, Jason E., Swem, Ted, Andersen, David E., Kennedy, Patricia L., and Nigro, Debora
Abstract:: Intrinsic and extrinsic factors affect vital rates and population-level processes, and understanding these factors is paramount to devising successful management plans for wildlife species. For example, birds time migration in response, in part, to local and broadscale climate fluctuations to initiate breeding upon arrival to nesting territories, and prolonged inclement...

Creator:: Kennedy, Patricia L., Bartuszevige, Anne M., Houle, Marcy, Humphrey, Ann B., Dugger, Katie M., and Williams, John
Abstract:: Potential for large prairie remnants to provide habitat for grassland-obligate wildlife may be compromised by nonsustainable range-management practices. In 1979–1980, high nesting densities of 3 species of hawks in the genus Buteo—Ferruginous Hawk (Buteo regalis), Red-tailed Hawk (B. jamaicensis), and Swainson’s Hawk (B. swainsoni)—were documented on the Zumwalt Prairie and...

Creator:: Bruggeman, Jason E., Swem, Ted, Andersen, David E., Kennedy, Patricia L., and Nigro, Debora
Abstract:: Critical information for evaluating the effectiveness of management strategies for species of concern include distinguishing seldom occupied (or low-quality) habitat from habitat that is frequently occupied and thus contributes substantially to population trends. Using multi-season models that account for imperfect detection and a long-term (1981-2002) dataset on migratory Arctic Peregrine...

Creator:: Wallace, Zachary P., Kennedy, Patricia L., Squires, John R., Olson, Lucretia E., and Oakleaf, Robert J.
Abstract:: Studies of anthropogenic impacts on wildlife may produce inconclusive or biased results if they fail to account for natural sources of variation in breeding performance and do not use probabilistic sampling at a scale functional for management. We used stratified random sampling and generalized linear mixed models to test hypotheses...

Creator:: Wallace, Zachary P., Kennedy, Patricia L., Squires, John R., Oakleaf, Robert J., Olson, Lucretia E., and Dugger, Katie M.
Abstract:: Grassland and shrubland birds are declining globally due in part to anthropogenic habitat modification. Because population performance of these species is also influenced by non-anthropogenic factors, it is important to incorporate all relevant ecological drivers into demographic models. We used design-based sampling and occupancy models to test relationships of environmental...
