New insights on an old topic : understanding the effects of forest harvest on trout in the context of climate

Creator:: Penaluna, Brooke E.
Abstract:: Studies of the effects of forest harvest on streams and fish have a long history in the Pacific Northwest. Results of this work have prompted development of new forest harvest practices that are more protective of these resources, but the effectiveness of these new practices has not been fully evaluated....

Evaluating the Ecological Trade-Offs of Riparian Thinning for Stream Ecosystems in Second-Growth Redwood Forests of Northern California

Creator:: Roon, David A.
Abstract:: Riparian forests provide a myriad of ecosystem functions for adjacent streams and rivers, and due to these linkages, changes in riparian forest conditions can have direct implications for stream ecosystems. Resource managers in the coast redwood forests (Sequoia sempervirens) of northern California (USA) are actively thinning second-growth stands to accelerate...

Comparison between thermophilic and mesophilic aerobic biological treatment of a synthetic organic waste

Creator:: Streebin, Leale E.
Abstract:: Temperature is one of the most important factors affecting microbial activity and consequently is of great importance in a biological waste treatment system. Extensive research has been carried out to determine the effects of temperature on biological reactions in the temperature range of 20° to 35° Centigrade. It is generally...

Regional changes in landscape pattern and carbon stores in the interior of British Columbia as determined by satellite imagery

Creator:: Sachs, Donald
Abstract:: The detection and mapping of large scale changes to forested landscapes is increasingly important in ecology and management. I used Landsat TM and MSS imagery to map forest cover in 1992 for a 4.2 million ha area of the interior of British Columbia with an overall classification accuracy of 79%....

The timber harvesting behavior of family forest owners

Creator:: Butler, Brett J.
Abstract:: To increase our understanding of the timber harvesting behavior of family forest owners, I developed theoretical and empirical timber harvesting models for family forest owners in the southeastern United States. An individual-choice model was the basis for the models. Family forest owners were modeled as utility-maximizers who made harvesting decisions...

A Comprehensive Mechanistic Study on Using Fine Lightweight Aggregate to Mitigate Alkali-silica Reaction

Creator:: Li, Chang
Abstract:: Previous research has shown that using fine lightweight aggregate (FLWA) can be a promising strategy to mitigate alkali-silica reaction (ASR) in mortar and concrete. While several possible theories were proposed by researchers, discrepancies in testing methods, materials, and supporting evidence still exist. Therefore, this study was initiated. There are two...

Taxonomy, paleoecology, and paleobiogeography of Wenlockian (Silurian) brachiopods of the Cape Phillips formation from Baillie Hamilton Island, Arctic Canada

Creator:: Zhang, Ning
Abstract:: Eighty-seven brachiopod species are described and illustrated from a brachiopod fauna of the Cape Phillips Formation of Baillie Hamilton Island, Arctic Canada. Two new families, Wangyuiidae and Rhynchotretidae, are proposed. Six new genera and forty-five new species are recognized. New genera comprise: Flabellitesia, Wangyuia, Pseudomendacella, Eoplectodonta (Paranisopleurella), Johnsonatrypa, and Dicoelospirifer....

Bacterial and Host Factors Contributing to Mycobacterium avium subspecies paratuberculosis Persistent Infection

Creator:: Phillips, Ida L.
Abstract:: Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne’s disease, a chronic granulomatous enteritis that plagues domestic and wild ruminants globally. During the silent stages of Johne’s disease, infected animals intermittently shed bacteria for years prior to clinical diagnosis during advanced disease stages. This strategy allows MAP to...

A Contingency-Based Evaluation for Beaver Restoration of Salmon Habitat in Oregon Coastal Streams

Creator:: Stevenson, John R.
Abstract:: Streams across the western United States are impaired from human alterations that have reduced freshwater habitat by simplifying channel complexity and disconnecting floodplains (Knox et al., 2022; Waples et al., 2008; Wohl, 2014). Climate change is likely to continue exacerbating these risks by warming summer surface stream temperatures (Crozier et...

Validity and Reliability of the Unsupervised, Isokinetic Three-Minute All-Out Cycling Test for Critical Power

Creator:: Bronson, Staci M.
Abstract:: PURPOSE: We tested the hypothesis that the unsupervised, isokinetic 3- minute all-out cycling test (3MT) would be a valid and reliable way to determine end power (EP) and work done above end power (WEP). Additionally, we hypothesized that EP would successfully demarcate between heavy and severe-intensity exercise and thus represent...
