Responses of pond-breeding amphibians to wildfire: Short-term patterns in occupancy and colonization
B. R. Hossack, P.S. Corn
2007, Ecological Applications (17) 1403-1410
Wildland fires are expected to become more frequent and severe in many ecosystems, potentially posing a threat to many sensitive species. We evaluated the effects of a large, stand-replacement wildfire on three species of pond-breeding amphibians by estimating changes in occupancy of breeding sites during the three years before and...
Seasonal movements and environmental conditions experienced by Pacific halibut in the Bering Sea, examined by pop-up satellite tags
Andrew C. Seitz, Timothy Loher, Jennifer L. Nielsen
2007, Scientific Report of the International Pacific Halibut Commission 84
Currently, Pacific halibut are managed as one population extending from California to the Bering Sea. However, we hypothesize that a spawning subpopulation of Pacific halibut exists in the Bering Sea. In this study, we examined the seasonal migration and depth-specific behavior of Pacific halibut in the Bering Sea, which serve...
