Small-mammal herpetofauna abundance in riparian and upslope areas of five forest conditions

Creator:: Gomez, Douglas M.
Abstract:: I compared species composition and relative abundance of'small mammals and herpetofauna between riparian and upslope habitats among 5 forest types. Riparian- and upslope- associated species were identified based on capture frequency. Small mammal species richness was similar between stream and upslope habitats and among the 5 forest types. There were...

A characterization of unmanaged riparian overstories in the central Oregon Coast Range

Creator:: Nierenberg, Tara R.
Abstract:: Riparian areas that can be used as reference sites on which to base goals of vegetation restoration have not been documented in the Oregon Coast Range. I examined the composition and distribution of unmanaged riparian overstories in the central Oregon Coast Range along nine streams which have experienced minimal disturbance...

Spatial pattern and dynamics of hardwood patches in the Coast Range of Oregon, 1939-1993

Creator:: Hess, Rebecca Susan
Abstract:: Analysis of the long-term spatial pattern and dynamics of hardwood patches in the Coast Range of Oregon provides numerous ecological insights. Natural and anthropogenic disturbances have contributed to the development of a patchy mosaic of vegetation types in the area. Some hardwood patches in the Coast Range may be the...

Riparian litter inputs to streams in the central Oregon Coast Range

Creator:: Hart, Stephanie K.
Abstract:: Riparian zone vegetation can influence terrestrial and aquatic food webs through variations in the amounts, timing, and nutritional content of leaf and other litter inputs. Differences in vegetation composition and density, as well as riparian topography, may modulate the strength and quality of these inputs. Changes in inputs to small...

The land-water interface : patterns of riparian vegetation and channel morphology in the Oregon Coast Range system

Creator:: Takahashi, Mayumi
Abstract:: This study was conducted to describe variation of riparian vegetation in an Oregon Coast Range system according to geomorphic characteristics and in relation to streamflow. Specific objectives of this study were to: I) examine if the vegetation composition and structure of the riparian forest varied among channel-reach morphologies, 2) examine...

Tree species-soils relationships in old-growth forests of the Oregon Coast Range

Creator:: Cross, Alison
Abstract:: Tree species directly and indirectly affect soil nutrient cycles. I sought to characterize soils and foliage associated with four common canopy tree species (Douglas-fir, western hemlock, western redcedar, and bigleaf maple) in mixed-species old-growth forests of the Oregon Coast Range and to determine whether and how soils differ among the...

Similarities in understory vegetation composition between unthinned, thinned and old-growth Douglas fir stands in western Oregon

Creator:: Mayrsohn, Cheryl
Abstract:: Forest stands were studied to determine if old-growth forest structure could be mimicked in younger stands via overstory manipulation. Cover and species composition of understory plants were systematically sampled in sixteen thinned second-growth stands and sixteen adjacent unthinned second-growth Douglas fir (Pseudotsuga menziesii (Mirabel) Franco.) stands. The stands were thinned...

The use of ơ15N and ơ¹³C to analyze food webs and identify source-sink relationships in riparian canopy vegetation of the Oregon Coast Range

Creator:: Scott, Emily E.
Abstract:: In the Coast Range of western Oregon, some natural resource managers are converting red alder-dominated riparian areas to conifers to increase the future source of in-stream large wood for salmonid habitat. However, studies in Alaska have shown red alder-dominated riparian areas support greater invertebrate biomass compared to conifer-dominated areas. In...

The clonal development of vine maple during Douglas-fir stand development in the Coast Range of Oregon

Creator:: O'Dea, Mary E.
Abstract:: Natural Douglas-fir stand development is the result of many types of disturbance, both natural and management induced. The magnitude and timing of these disturbances have profound effects on the structure and composition of both the overstory and understory plant communities. Vine maple responds to disturbance by basal sprouting, layering, producing...

The influence of canopy type and seasons on adult aquatic insect emergence and riparian spiders in the Oregon Coast Range

Creator:: Premdas, Sharmila
Abstract:: The objective of my study was to examine differences in riparian tree and shrub composition associated with adult aquatic emergence and implications for terrestrial spiders in these sites. Seasonal abundance and biomass of adult emergent aquatic insects, riparian arthropod abundances and spider densities were compared between conifer- and hardwood-dominated sites...
