Rising global temperatures are having lasting effects on mountain snow environments in the form of diminishing snowpacks, shorter accumulation seasons, and shifts in meltwater timing. Seasonal snowpack is a vital source of water for natural and human systems. In the forested mountain landscapes of the Pacific Northwest seasonal snowmelt feeds...
Background: Low drop cushioned running shoes have been popular over the past decade despite a lack of research on low drop shoes. There is some evidence that low drop cushioned shoes increase vertical ground reaction forces (VGRFs) and influence ankle kinematics but no study to date has focused on large...
Rare plant reintroductions are a critical conservation tool for the augmentation of diminishing populations, or re-establishment of extirpated populations. Analysis of reintroduction failures suggests that a sophisticated understanding of species biology, ecology, and habitat is essential for producing self-sustaining rare plant populations. This study sought to generate that background knowledge...
Pseudoloma neurophilia is the most common pathogen reported in zebrafish (Danio rerio) research facilities and is an important threat to the zebrafish model. This microsporidian parasite can cause clinical disease, but more importantly is a causative agent of non-protocol induced variation in research. Studies utilizing infected zebrafish, could potentially confound...
Forests play an integral role in the global carbon cycle, regulating the atmospheric CO₂ concentration by sequestering nearly one third of anthropogenic carbon emissions and storing carbon for centuries. Forest ecosystems are integrated into the culture, ecology, and economy of western North America, supporting wildlife habitat, local economies, recreation, and...
Anadromous salmonid populations in the Pacific Northwest have declined over the past 150 years. In 1999, wild spring Chinook salmon (Oncorhynchus tshawytscha) were federally listed as threatened within the Willamette Basin, OR. Currently, practices to restore wild populations in the upper Willamette Basin involve trapping wild adults at the base...
School Physical Education programs provide key opportunities to promote lifetime physical activity (PA) to students, while at the same time students can build a sense of enjoyment. The purpose of this study first sought to determine the effects of varying instructional approaches on the enjoyment and PA levels of students...
This is the second of two new reports sponsored by a consortium of public groups and focusing on the Western Pond Turtle (Emys marmorata marmorata). The first report (Adamus 2003) provided an updated perspective on the distribution of the species in the Willamette River Basin, based on new field surveys,...
