During the past decade (1978-87), breeding success and
productivity of bald eagles on the lower Columbia River (LCR) has
been far below state and regional averages and well below levels
required for delisting under the Endangered Species Act by the
Pacific States Bald Eagle Recovery Plan. Human disturbance was
Species distribution models (SDMs) are currently being used to identify essential fish habitat and guide
fisheries management worldwide. We present SDMs based on generalized linear mixed models (GLMM) of
the fall distribution or occurrence of juvenile American shad (Alosa sapidissima) and juvenile striped bass
(Morone saxatilis) in the Hudson River...
Human-induced fragmentation of forests is increasing, yet the consequences of these landscape changes to vertebrate communities are poorly understood. Despite progress in our understanding of how bird communities
respond to forest fragmentation caused by agricultural or urban development, we have little understanding of these dynamics in landscapes undergoing intensive forest...
