Biologists have long been fascinated with reproductive traits, in part because they are frequently exaggerated or showy, and they commonly vary among closely related species. Exaggerated sexual traits, in particular, have been the focus of intense empirical and theoretical research, but most of this work has focused on traits involved...
The results of experiments conducted in 1957 and 1958 to
isolate the cause of post-transportation mortalities among hatchery-reared
rainbow trout, Salmo gairdneri Richardson, in Oregon are
reported. Although death rate varies greatly, the average loss
occurring from one to seven days following liberation has been estimated
to be ten percent...
A five-year clipping experiment was conducted to determine maximum sustained utilization levels for three big game browse plant species in
central Arizona. The three species were mountain-mahogany (Cercocarpus
breviflorus) and desert ceanothus (Ceanothus Greggii) in the chaparral
type, and cliff-rose (Cowania mexicana var. Stensburiana) in the pinyon-juniper type. Experimental treatments...
The purpose of this study was to understand the impact of faculty-to-faculty mentoring programs on the experiences of both mentors and first-year instructor protégés in Career and Technical Education (CTE) programs with an emphasis on practitioner-educators in nursing and in welding-fabrication. The study was undertaken for four reasons: (a) increases...
The western United States has experienced large-scale degradation due to land use and land cover changes, invasion of annual grasses, and expansion of woody plants into grass and shrublands and the resultant altered fire regimes. These landscape-scale changes have coincided with declining mule deer (Odocoileus hemionus) populations, making habitat loss...
This analysis is the study of Oregon's wildlife resources from
the period prior to white settlement up to the present time, including
critical projections, based on present trends and expected conditions
for both human and wildlife populations in the state up to the year 2010.
Prior to white settlement Oregon...
