| 2017-11-22 | Environmental and ecological conditions at Arctic breeding sites have limited effects on true survival rates of adult shorebirds | Many Arctic shorebird populations are declining, and quantifying adult survival and the effects of anthropogenic factors is a crucial step toward a better understanding of population dynamics. This study used a recently developed, spatially explicit Cormack–Jolly–Seber model in a Bayesian framework to obtain broad-scale estimates of true annual survival rates for 6 species of shorebirds at 9 breeding sites across the North American Arctic in 2010–2014. No factors broadly affected survival across species. Overall, the findings suggest that annual survival rates of adult shorebirds are generally robust to conditions at Arctic breeding sites. Instead, conditions at migratory stopovers or overwintering sites might be driving adult survival rates and should be the focus of future studies. | Environmental and ecological conditions at Arctic breeding sites have limited effects on true survival rates of adult shorebirds |
