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...
There are conflicts between commercial and agricultural
uses of land bordering U. S. Highway 201 southbound from
Ontario, Oregon. A questionnaire was developed and administered
to businesses located along Highway 201 to determine the most
important location factors for commercial users of the ribbon
development. The most important factors were...
Due to a number of disadvantages associated with the use of antibodies as
affinity stationary phases, researchers have recently began to explore the use of RNA
and DNA aptamers for use as affinity stationary phases. These molecules have been
shown to be a viable choice for applications in many methods...
Wetland prairies of the Willamette Valley, considered among the rarest of Oregon’s ecosystems, are threatened by invasion of woody species and non-native species. Because of its historical importance, fire is a top choice of managers for preventing the encroachment of woody species. However, the effects of prescribed burning on present...
In September 2000, the Convention for the Conservation and Management of the Highly Migratory Fish Stocks in the Central and Western Pacific (WCPFC) was concluded by the seventh session of the Multilateral High Level Conference (MHLC). The WCPFC, amongst other things, establishes a tuna Commission, which will have powers to...
An experiment was conducted to evaluate the influence of forest fuels reduction on diet quality, botanical composition, relative preference, and foraging efficiency of beef cattle grazing at different stocking rates. A split plot factorial design was used, with whole plots (3 ha) being fuel reduced or no treatment (control), and...
