Post-harvest establishment influences ANPP, soil C and DOC export in complex mountainous terrain

Creator:: Peterson, Fox S.
Abstract:: The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem stocks and functions, such as soil organic carbon (SOC), dissolved organic carbon (DOC), and belowground productivity have also been related to the...

Winter den sites of northern flying squirrels in Douglas-fir forests of the south-central Oregon Cascades

Creator:: Feen, Jeffrey S.
Abstract:: I studied selection of winter den sites by northern flying squirrels (Glaucomys sabrinus) in forests of the Oregon Cascades. Fifty-six squirrels were radio-collared in three managed, 80- to 1 30-year-old Douglas-fir stands on the Umpqua Nationa Forest during the winters of 1994-95 and 1995-96. Squirrels were located at their den...

Watershed-scale vegetation patterns in a late-successional forest landscape in the Oregon Coast Range

Creator:: Wimberly, Michael C.
Abstract:: Knowledge about vegetation patterns and ecological processes in unmanaged, late-successional watersheds is needed to provide a foundation for forest management strategies aimed at conserving native biodiversity. I examined influences of environmental variability and disturbance history on forest structure and composition in the Cummins Creek Wilderness, located on the central Oregon...

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...

Impacts of dredged material disposal on estuarine benthic macrofaunal communities in Coos Bay, Oregon

Creator:: Erman, Lisa T.
Abstract:: Hopper dredge disposal of coarse grained sediment was investigated between May and September, 1986, at a designated disposal area, Site G, in Coos Bay, Oregon. The objectives of the study were to: (a) identify and describe the benthic macrofaunal community structure at Site G during May and September, 1986; (b)...

An Analysis of Nutrient Depletion in Douglas-fir Forests of the Oregon Coast Range

Creator:: Siah, Kaveh G.
Abstract:: Nutrient limitation constrains tree growth in many managed forests. Nitrogen (N) is the most common limiting nutrient, but high N supply can shift limitation to other nutrients, particularly phosphorus (P) and the base cations calcium (Ca), magnesium (Mg), and potassium (K). As different soil minerals have different capacities to supply...

Using a species-centered approach to examine patterns and drivers of avian species richness in the Rogue Basin, Oregon, A 'bird's eye view' : using a species-centered approach to examine patterns and drivers of avian species richness in the Rogue Basin, Oregon

Creator:: Halstead, Katherine E.
Abstract:: 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...

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)...

The roles of provenance and phylogeny in recruitment, community assembly, and species coexistence in invaded California grasslands

Creator:: Brandt, Angela J.
Abstract:: Biological invasions pose one of the greatest threats to global biodiversity, but many naturalized invaders coexist with the native community. Community ecology theory provides a framework for understanding the mechanisms by which invaders might coexist with native species or exclude them from the community, thus informing management practices to maximize...
