Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...
Condors and vultures comprise the only group of terrestrial vertebrates in the world that are
obligate scavengers, and these species move widely to locate ephemeral, unpredictable, and patchily-distributed
food resources. In this study, we used high-resolution GPS location data to quantify
monthly home range size of the critically endangered California...
Condors and vultures are distinct from most other terrestrial birds because they use extensive soaring flight for their daily
movements. Therefore, assessing resource selection by these avian scavengers requires quantifying the availability of
terrestrial-based habitats, as well as meteorological variables that influence atmospheric conditions necessary for soaring. In
this study,...

The purpose of this study is to examine the relationship between land management practices of Indian communities prior to contact with Europeans and the nature or character of subsequent catastrophic forest fires in the Oregon Coast Range. The research focus is spatial and temporal patterns of Indian burning across the...
Ecological niche models can be a useful tool to identify candidate reintroduction sites for endangered
species but have been infrequently used for this purpose. In this paper, we (1) develop activity-specific
ecological niche models (nesting, roosting, and feeding) for the critically endangered California condor
(Gymnogyps californianus) to aid in reintroduction...
