Some of the most pressing conservation concerns involve declining populations of species with low fecundity and highly specialized foraging and reproductive requirements. Yet, we often lack a functional understanding of how individuals of those species interact with their environment, specifically how their movement is affected by human-induced changes. In order...
The distribution of American martens (Martes americana) within Sagehen Creek Experimental Forest (SCEF), Tahoe National Forest, California has been periodically documented from 1980–1993. This area has been the location of nine marten surveys, each involving a systematic detection/nondetection survey on the same grid. These data are an unprecedented time series...
Although short-tailed weasels (Mustela erminea) are important predators of small mammals, little is known about their space use, habitat selection, or vulnerability to predation in North America. To evaluate the effects of forest management and social structure on home range size and habitat selection of short-tailed weasels, I conducted a...
Shattering is a natural phenomenon of floret and spikelet disarticulation across
abscission layers of the pedicel and rachilla, respectively, after seed maturation. Seed
shattering in cool-season grasses and native grass species is an economic problem in seed
production.
This study was conducted to determine whether the use of the plant...
The present experiment examined children's memory for stereotypic
and non-stereotypic sex role content in their reading material.
Twenty-four male and twenty-four female fifth grade subjects read
two short stories, each depicting a male and female character who
exhibited an equal number of masculine and feminine traits and
behaviors. Results of...
Riparian zones provide habitat for breeding birds in the semiarid western United States; however, there are few data available that address the effects of livestock grazing strategies on riparian habitats and avian communities. Documenting avian community composition in different riparian vegetation communities and relating vegetation communities to livestock grazing strategies...
This thesis uses a hedonic price model to estimate the value of water for irrigation in Deschutes County, Oregon. The analysis uses a dataset comprising information on 2,274 agricultural parcels across the County. Uniquely, the analysis successfully utilizes assessor-determined real market values in the place of actual land sales. A...
The purpose of this study was to understand the lived experience of students to discern the impact of their interaction with the food pantry. This knowledge may, in turn, influence future food pantry methods and wider policy, both at PNW College and more broadly. Not only does student hunger have...
