The purpose of this study was to explore the possible relationship among fashion media, the social responsibility agenda of the Audubon Society, and the use of birds in millinery in the late nineteenth and early twentieth centuries. Both the content analysis method and the historic method were used to gain...
The concept of compensatory mitigation is well established as an approach to environmental management. In the past, mitigation programs have been used to conserve wetlands affected by development, and is proposed as a cost-effective approach to offsetting greenhouse gas emissions through reforestation programs. The concept may be equally applicable to...
The combined effects of habitat loss, degradation, and fragmentation pose a serious threat to Earth's biodiversity, imperiling even relatively common species. 'Habitat' is necessarily a species-specific concept, and investigations of bird diversity relationships and subsequent efforts to prioritize conservation areas, are challenged by the difficulty of estimating complex habitat gradients...
Models that assess the risk to biodiversity from landscape change can help
communities prioritize planning decisions. Accurate representation of the ecology and
life history traits of species is necessary. This study introduces the use of habitat
quality in a biodiversity risk model to determine the significance of habitat quality when...
The Independent Multidisciplinary Science Team (IMST) was directed to evaluate the extent of predatory impacts of marine mammals and seabirds on salmonids and to recommend actions to mitigate impacts. IMST focused on the Oregon Department of Fisheries and Wildlife Action Plans because they provide the programmatic direction for the State...
North American sagebrush (Artemisia spp.) ecosystems are suffering from
reductions in habitat extent and quality. Only about 50% of sagebrush remains
from pre-settlement conditions, and much of the remaining habitat is
fragmented or degraded by invasive species, fire suppression and overgrazing.
Sagebrush-obligate species are experiencing population declines as a result...
Over one third of the earth’s land surface has been modified to some extent for agricultural purposes. The large global footprint of agriculture, combined with the knowledge that existing reserve networks are likely insufficient for long-term conservation of native biodiversity, has necessitated that agricultural systems contribute to conservation of native...
