Evaluation of allelopathy as a mechanism by which buckwheat suppresses Canada thistle and its mycorrhizae

Creator:: Eskelsen, Steven R.
Abstract:: Experiments were conducted to determine if allelopathy is a mechanism by which buckwheat interferes with a) the growth of Canada thistle and/or b) mycorrhizae colonization in Canada thistle roots. In a competition experiment, buckwheat plant biomass was only affected by the intraspecific competition from other buckwheat plants and not by...

Biology and adult variability in an Oregon population of Leptarctiacaliforniae (Walker) (Lepidoptera: Arctiidae)

Creator:: Mays, David Lee
Abstract:: Leptarctia californiae (Walker) was studied on clear and semi-forested southern slopes in the Coast Range Mountains of Benton County, Oregon. The spring of 1965 had an unusually long warm period (21 days) resulting in adult emergence approximately 25 days earlier than in the cooler spring of 1966. Peak flight activity...

Describing grey literature again: a survey of collection policies

Creator:: Lehman, Heather and Webster, Janet G.
Abstract:: At Oregon State University, we are exploring the differences between collections formed by digitizing existing materials on our shelves and those created by identifying and acquiring digital objects beyond our library. One example is the proposed Tsunami Digital Library (TDL) that would support a growing research program with users needing...

Butterfly and flower community composition among prairie-oak ecosystem habitats in the Willamette Valley, Oregon

Creator:: Powers, Breanna F.
Abstract:: Prairie-oak ecosystems in the Willamette Valley, Oregon have experienced habitat loss and degradation; most of these ecosystems are fragmented into smaller patches. Prairie-oak butterfly species, in the Willamette Valley, have decreased dramatically due to loss or degradation of habitat. More research is needed on sustaining the populations of butterflies in...

Butterflies of the H.J. Andrews Experimental Forest : biological inventory and ecological analysis

Creator:: Ross, Dana N. R.
Abstract:: A biological inventory of the butterflies of the H. J. Andrews Experimental Forest [HJA] in Linn/Lane County, Oregon was conducted during 1994 and 1995. It was the first comprehensive survey of HJA butterflies for the site and serves as a baseline for future butterfly research. A detailed ecological account is...

Quasi-stationary atmospheric responses to large-scale forcing

Creator:: Kang, In-sik
Abstract:: A time-dependent, spectral, barotropic model and a similar two-layer primitive equation model are developed to investigate the planetary-scale wave responses to various types of large-scale forcing: vorticity and heat sources, and sea surface temperature (SST) anomalies. Both models are linearized about the zonal mean states of January climatology. The characteristics...

Mass transport in laboratory water wave flumes

Creator:: Kim, Tae In
Abstract:: A complete solution, exact to second-order, for wave motion forced by a hinged-wavemaker of variable-draft is presented. A solution for a piston type wavemaker is also obtained as a special case of a hinged-wavemaker with negative infinite draft. The existing Stokes inviscid theories for mass transport is extended to include...
