| helminth parasites of northern spotted owls (strix occidentalis caurina) from oregon. | helminth parasites are reported for the first time from northern spotted owls. seventy-one percent of a sample of strix occidentalis caurina from western oregon was infected. nematodes (porrocaecum depressum, capillaria falconis, microtetrameres sp. and synhimantus hamatus) were the most prevalent parasites although cestodes (paruterina rauschi) and acanthocephalans (centrorhynchus conspectus) were also represented. there was an association between components of this helminth fauna and the diet ... | 1989 | 2716105 |
| evaluating carbon storage, timber harvest, and habitat possibilities for a western cascades (usa) forest landscape. | forest policymakers and managers have long sought ways to evaluate the capability of forest landscapes to jointly produce timber, habitat, and other ecosystem services in response to forest management. currently, carbon is of particular interest as policies for increasing carbon storage on federal lands are being proposed. however, a challenge in joint production analysis of forest management is adequately representing ecological conditions and processes that influence joint production relations ... | 2016 | 27755743 |
| evaluating areas of high conservation value in western oregon with a decision-support model. | the northwest forest plan was implemented in 1994 to protect habitat for species associated with old-growth forests, including northern spotted owls (strix occidentailis caurina) in washington, oregon, and northern california (u.s.a.). nevertheless, 10-year monitoring data indicate mixed success in meeting the ecological goals of the plan. we used the ecosystem management decision-support model to evaluate terrestrial and aquatic habitats across the landscape on the basis of ecological objective ... | 2010 | 20184658 |
