Estes, J.A., D.R. Lindberg, and C. Wray, 2005. Evolution of large body size in abalones (Haliotis): patterns and implications. Paleobiology 31(4): 591-606 Paper examining how and when large body size in abalones developed.
Gray wolves are listed as "endangered" under the Oregon Endangered Species Act. The law requires the Oregon Fish and Wildlife Commission to conserve the species in the state.
Effective voluntary conservation programs consider a range of factors. For example, they are adaptable to the needs of individual landowners, unique ecological conditions, and strategic conservation goals. This report profiles voluntary programs. Written by Bobby Cochran and Cheryl Hummon in 2005.
Red Wolf Ecotourism Report
The New Mexico Department of Game and Fish analyzed the feasibility of reintroducing river otters (Lontra canadensis) to one or more river systems in that state. The Conservation Economics Program was contracted by Amigos Bravos - Friends of the Wild Rivers, to estimate the economic benefits that reintroduction can be expected to generate on behalf of the River Otter Working Group.
Under the Endangered Species Act, the US Fish and Wildlife Service must determine the economic impacts of designating critical habitat for the recovery of a listed species. The Conservation Economics Program has developed a state-of-the-art method for identifying and estimating all economic impacts, including benefits, of designating critical habitat. The Canadian Lynx serves as a case study with research focused in representative areas of Montana and Maine.
This report was commissioned by Defenders of Wildlife through a generous grant from the Alex C. Walker Educational and Charitable Foundation. Dr. Gail Lash and Ms. Pamela Black of Ursa International conducted the research and wrote the report, which summarizes survey findings for those potential participants who would "supply" ecotourism services centered on the red wolf, and the potential tourists who would "demand" ecotourism services.
The U. S. District Court rules for Defenders, specifically finding that the FWS’ actions were illegal because the agency reduced protections for wolves without determining that the species occupied all of the areas of its historic range that are required to ensure that the species will effectively recover. Wolves are once again offered full protections under the ESA.
