Disturbance and Environmental Effects on Staging Roseate Tern Parent-Offspring Interactions and Hatch Year Survival at Cape Cod National Seashore
… was designed to address objectives related to hatch-year (HY) ROST behavior and survival in response to human and non-human activities and environmental variables at CCNS. Behavioral data showed that disturbance, specifically human and non-human activities, were related to increased HY ROST …

Management and Mother Nature: piping plover demography and condition in response to flooding on the Missouri River
… and the Barker model in RMARK to estimate hatch-year (HY) and after hatch-year (AHY) survival and fidelity to our study area. We then used estimates from these analyses to calculate reproductive output, reproductive output necessary for a stationary population, and population growth (λ). …

ECOTOXICOLOGICAL IMPACTS OF RUN-OF-RIVER DAMS ON THE AMERICAN DIPPER (CINCLUS MEXICANUS) AND MOUNTAIN STREAM FOOD WEBS
… river bird that occupies mountain streams year-round and is a well-described indicator of stream health; thus, it is an ideal species to study potential impacts of RoR hydropower on river food webs. From August 2014 to November 2015, I conducted seasonal river bird surveys at 14 streams in …

Population Dynamics of Threatened Piping Plovers on the Niobrara River, Nebraska
… models, respectively. We monitored 1,874 banded hatch-year and adult birds across the regional population (Niobrara River, Lewis and Clark Lake, Gavins Point Reach segment of the Missouri River), and used multi-state mark-recapture models to estimate survival and inter-annual dispersal …
