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...

Decomposition and nitrogen dynamics of red alder and Douglas-fir leaf litter in Oregon Coast Range riparian forests

Creator:: Matkins, Joselin
Abstract:: I examined factors regulating decomposition rates of red alder (Alnus rubra)) and Douglas-fir (Pseudotsuga menziesii) leaf litter in Coast Range riparian areas in western Oregon. Overall, this study was designed to examine the influence that leaf litter quality characteristics and decomposition site treatment have on decomposition rates, to provide a...

Biomass dynamics of dead Douglas-fir and western hemlock boles in mid-elevation forests of the Cascade Range

Creator:: Graham, Robin Lee Lambert
Abstract:: The rate and manner of bioniass loss from decomposing Douglas-fir and western hemlock boles in mid-elevation forests of the central Cascade Range were measured. Bole bark and wood were considered separately. Loss of bole wood due to respiration was measured by change in bole wood density. Loss of bole wood...

The effect of fire regime on coarse woody debris in the west central Cascades, Oregon

Creator:: Wright, Pamela J.
Abstract:: This study examined the effect of fire regime on coarse woody debris (CWD) mass using a combination of field data and modeling. The objectives were to use field sampling to determine how CWD differs between two areas that have had different fire regimes, and investigate how fire frequency and severity,...

Small mammal relationships with downed wood and antelope bitterbrush in ponderosa pine forests of central Oregon

Creator:: Smith, Troy G.
Abstract:: Downed wood and antelope bitterbrush (Purshia tridentata) are often managed on federal ponderosa pine (Pinus ponderosa) forests in central Oregon to prevent catastrophic wildfires and provide wildlife habitat. However, although much is known regarding the roles of downed wood and bitterbrush in wildfire behavior, little is known regarding the relationships...

Urban owners of forests in western Oregon

Creator:: Downing, Kent., Connaughton, Kent P., Hopkins, Walter S., and Oregon State University. Forest Research Laboratory
Abstract:: Urbanites who own forest land belong to a larger category of owners often referred to as small woodland owners. As a group, small woodland owners have been the subject of much investigation. Little research, however, has focused specifically on urban-dwelling owners who, as defined by the Census Bureau, live in...

Litter controls of microbial community composition and function in forest soils

Creator:: Brant, Justin B.
Abstract:: Most carbon (C) transformations in soil are carried out by a diverse and complex soil microbial community. The size and composition of the soil microbial community is determined by poorly understood interactions between the quantity and chemical composition of plant inputs, as well as climate. Given the metabolic diversity of...

Nitrogen and phosphorus dynamics during decomposition of multiple litter types in temperate coniferous forests

Creator:: van Huysen, Tiffany L.
Abstract:: Litter nutrient dynamics contribute significantly to biogeochemical cycling in forest ecosystems. These dynamics may be influenced by site attributes, litter nutrient concentrations, and soil nutrient availability either independently or synergistically. Litter nutrient dynamics were examined in two decomposition studies in temperate coniferous forests of Oregon. I used ¹⁵N-labelled litter of...

Homogenization of Detrital Leachate in an Old-Growth Coniferous Forest, OR : DOC Fluorescence Signatures in Soils Undergoing Long-Term Litter Manipulations

Creator:: Strid, April R.
Abstract:: Soil dissolved organic carbon (DOC) is a small but crucial part of the forest carbon cycle. Characterizing the relationship between detrital inputs and soil DOC chemistry is crucial to understanding the ultimate fate of root carbon, fallen wood and needles. Chemical differences in the DOC pool may help to explain...
