Cross-seasonal effects in the American Woodcock: conditions prior to fall migration relate to migration strategy and its implications for conservation

Clayton Graham, Tanner Steeves & Scott McWilliams
How post-breeding habitat quality and body composition of migratory birds carry over to influence fall migration strategies and residency merits consideration when creating cross-seasonal conservation plans, especially in breeding populations that are partial migrants. We assessed the influence of post-breeding habitat quality on departure body composition and fall migration patterns in a southern New England breeding population of American Woodcock (Scolopax minor). Woodcock that overwintered near breeding areas (n=5) had less fat upon capture in...

Data from: Modeling spatiotemporal abundance of mobile wildlife in highly variable environments using boosted GAMLSS hurdle models

Adam Smith, Benjamin Hofner, Juliet S. Lamb, Jason Osenkowski, Taber Allison, Giancarlo Sadoti, Scott McWilliams & Peter Paton
1. Modeling organism distributions from survey data involves numerous statistical challenges, including zero-inflation, overdispersion, and selection and incorporation of environmental covariates. In environments with high spatial and temporal variability, addressing these challenges often requires numerous assumptions regarding organism distributions and their relationships to biophysical features. These assumptions may limit the resolution or accuracy of predictions resulting from survey-based distribution models. 2. We propose an iterative modeling approach that incorporates a negative binomial hurdle, followed by...

Hypoxia-induced predation refuge for northern quahogs (Mercenaria mercenaria) in a temperate estuary

Bryan Galligan, Yoel Stuart, M. Conor McManus & Heather Stoffel
Oxygen depletion in estuaries and coastal waters is often associated with reduced biodiversity, coastal dead zones, and the loss of important ecosystem services. However, some species can benefit from low oxygen conditions due to the indirect effects these conditions have on trophic relationships. In Narragansett Bay, Rhode Island, U.S.A., northern quahogs (Mercenaria mercenaria) reach their highest densities in the areas of the Bay most prone to oxygen depletion. One line of evidence suggests that suboxic...

Migration tactics and connectivity of a Nearctic-Neotropical migratory shorebird

John Herbert
During long-distance spring migrations, birds may rest and refuel at numerous stopover sites while minimizing the time to reach the breeding grounds. If habitat is limited along the migration route, pre-breeding birds optimize flight range by having longer stopovers at higher quality sites compared to poorer quality sites. Stopover duration also depends on distance remaining to breeding grounds, ecological barriers, and individual characteristics. We assessed spring migration tactics and connectivity of a Nearctic-Neotropical migratory shorebird,...
