Relationships of green-tree retention following timber harvest to forest growth and species composition in the western Cascade Mountains

Creator:: Rose, Coulter R.
Abstract:: National Forest management in the Pacific Northwest is shifting from a focus on commodity production to ecosystem management, in which the health of the entire forest ecosystem is considered, rather than that of a few key species. Ecosystem management includes retention of some live trees following timber harvest (green-tree retention)...

Pendent Usnea (Lichens; Ascomycetes; Parmeliaceae) in Western Oregon : taxonomy; morphological characters; and geographical distribution

Creator:: Pittam, Sherry K.
Abstract:: Pendent Usnea species were collected in western Oregon and examined. Character states, such as cortex-medulla-axis ratio; fibril length; papilla diameter; branching patterns; and presence or absence of fibrils, papillae, soredia, isidia; plus chemistry, were recorded and analyzed by inspection for differences. Historical names were researched in the literature. A comparison...

The species composition, density, and distribution of the littoral zooplankton assemblage in Crater Lake, Oregon

Creator:: Warncke, William Madara
Abstract:: The species compositions and densities of the littoral and pelagic zooplankton assemblages in Crater Lake were compared. The littoral and pelagic zooplankton assemblages of most lakes are typically different due to different habitat conditions in the two zones. The littoral zone of Crater Lake lacks many of the habitat characteristics,...

Ecological implications of trout introductions to lakes of the Selway Bitterroot Wilderness, Idaho

Creator:: Bahls, Peter F.
Abstract:: The widespread introduction of trout to naturally fishless mountain lakes in the western United States has been accompanied by little research. The ecological role of trout populations occurring in 91 lakes of the central Selway Bitterroot Wilderness, Idaho, was examined with respect to 1) the sampling variability of biological and...

Subalpine revegetation on backcountry campsites near Tuolumne Meadows, Yosemite National Park, California : third year results

Creator:: Moritsch, Barbara J.
Abstract:: The National Park Service initiated a backcountry campsite restoration project in 1987 to restore native vegetation on severely degraded campsites in three subalpine lake basins in Yosemite National Park. Restoration treatments included soil scarification, transplanting, manual seeding and site protection. Eight of the treated campsites were monitored in 1990 to...

The ecological consequences of the reduction of species diversity : experimental approaches

Creator:: Allison, Gary William
Abstract:: The influence of loss of diversity on community dynamics and ecosystem functioning has recently received considerable attention. Although study of biodiversity has a long history within ecology, empirical investigations exploring consequences of loss have been rare. Because many factors confound diversity comparisons, experimental manipulations of diversity offer the most direct...

Developing models to predict favorable environments for rice blast

Creator:: Calvero, Silvino B.
Abstract:: Statistical analyses were used to develop predictive models of rice blast and to relate the favorability of environment to disease incidence and severity on different rice cultivars at five sites in Asia. The WINDOW PANE program was used to search for weather factors highly correlated with blast. Stepwise and r-square...
