요약 | Anthropogenic climate and land-use change are widely considered to be the two greatest threats to global biodiversity and ecosystem functioning. Although species may respond to changing environments in a variety of ways, the majority of species |
요약 | To investigate the combined effects of climate and land-use change on species occupancy and community composition, I surveyed avian diversity at 71 sites in the California Central Valley and Los Angeles. These sites were originally surveyed in t |
요약 | Our knowledge of species' ecological and life history traits as predictors of sensitivity to land-use change is well developed, but the same cannot be said for traits as predictors of climate-induced range shifts. There is strong theoretical sup |
요약 | Both climate and land-use change are expected to favor exotic and generalist species over specialists, resulting in declining occupancy and diversity. Using occurrence data for 122 bird species from 41 resurvey sites in the California Central Va |
