Field studies were conducted in 1998 and 1999, to evaluate glyphosate and glufosinate for control of redroot pigweed, common lambsquarters, hairy nightshade, and barnyardgrass in herbicide-resistant sugarbeets. Treatments that included two or three applications of glyphosate, regardless of rate, or glyphosate applied once in combination with BAS 656 07 H...
The Natural Resources Division (NRD) of the Confederated Tribes of Grand Ronde (CTGR), in cooperation with the Bureau of Indian Affairs (BIA), proposes the regeneration harvest and commercial thinning of four timber sales on the Reservation of The Confederated Tribes of Grand Ronde (CTGR).

Chlamydiae are obligate intracellular bacterial pathogens with a unique biphasic life cycle that consists of an infectious but non-dividing form, called elementary bodies (EB), and a noninfectious but metabolically active form, called reticulate bodies (RB). Chlamydia has an unusual process of cell division of which still remains uncharacterized subject matter;...
Salmon restoration has become a major priority in the Pacific Northwest. In the State of Oregon, much of
the responsibility for habitat restoration has fallen on local watershed councils, with the majority of their
funding coming from state and federal grants. Funding limitations, including the amount of funds allotted
to...
Situated off the west coast of Vietnam in the Gulf of Thailand, Phu Quoc archipelago and its waters are well-known for their rich natural resources, especially the bounty of fishery resources. Under increasing pressure from the growing population, fishing, and tourism development, there is a strong need to formulate an...

PURPOSE: To determine physical, plankton and nutrient/chemical conditions over the continental
margin for climate change studies in NE Pacific. In particular, to make CTD and CTD/rosette and net
tow stations along one line off Newport, OR, and to make continuous observations of currents using
ADCP and of surface-layer temperature, salinity...
Kincaid's lupine (Lupinus sulphureus ssp. kincaidii [Smith] Phillips) is a federally listed Threatened plant of Willamette Valley prairies. Both low reproduction, due to seed coat dormancy, and competition from invasive plants may threaten the longterm viability of this species. In separate studies, I investigated seed germination and an invasive species...

The unusually large amount of ice, snow,
and wind-damaged trees that occurred
during the winter of 1996-97 provided prime
habitat for populations of the Douglas-fir
beetle (DFB) (Dendroctonus pseudotsugae)
to build to epidemic numbers. Beetles
emerged during the spring and summer of
1998, attacking hundreds of thousands of
standing Douglas-fir...
