Knowledge of post-dispersal seed fates and other regeneration characteristics is
crucial for predicting abundances and distributions of populations and, ultimately,
community species composition and diversity. Seed fate studies, however, are rare
primarily due to the difficulty of determining seed fates and causes of mortality.
This thesis investigated post-dispersal seed fates...
Although a concern for gender equity provided the framework for this research,
the results of this study highlighted the fact that the question of equity should be
broadened to include concern for the tier of talented women and men who currently
choose not to persist in an undergraduate computer science...
Nutrition effects productivity of grouse. Females that obtain
high nutrient diets in spring produce larger clutches and larger, more
viable chicks than hens on less nutritious diets. Grouse select high
nutrient foods to help ensure proper nutrition. Reduced productivity
accounted for the decline of sage grouse (Centrocercus urophasianus)
populations in...
Responses of biological indicators of soil quality to winter cover cropping were measured on soil samples collected from 6 commercial growers' fields and two experiment research stations in the Willamette Valley of Oregon. The research stations were the North Willamette Research and Extension Center (Aurora, OR), and the Oregon State...
