Frequency, Distribution, Ploidy Diversity and Control Options of Herbicide Resistant Italian Ryegrass (Lolium perenne L. spp. multiflorum (Lam.) Husnot) Populations in Western Oregon

Creator:: Bobadilla, Lucas K.
Abstract:: Italian ryegrass (Lolium perenne L. spp. multiflorum (Lam.) Husnot) is one of the most troublesome weeds with respect to herbicide resistance selection. Some reasons for this are the numerous documented cases of multiple and cross herbicide resistance and some of the biological characteristics of this species, such as wind cross-pollination...

Methane emissions from typical manure management systems

Creator:: Steed, John Arthur
Abstract:: Methane is the most abundant organic chemical in the earth's atmosphere. Its abundance in the atmosphere is increasing with time and has reached levels not seen in recent geological history. The methane is produced both naturally, and anthropogenically. One of the sources of anthropogenic methane is manure from domesticated animals....

Integrating restoration and ecologically based weed management practices for invasive knotweed control

Creator:: Rudenko, Melody
Abstract:: Japanese knotweed is an invasive perennial shrub that dominates riparian ecosystems. Effective management techniques are currently limited to repeated annual herbicide applications and there is little science-based information about which control tactics result in the greatest management success. Restoration of invaded sites to a functioning riparian plant community is needed...

Diversity and similarity of benthic fauna off Oregon

Creator:: Stander, Jeffrey M.
Abstract:: Samples of benthic organisms off the coast of Oregon, taken from depths varying from 50 to 2900 meters, have been analyzed in terms of diversity at a given station, and similarity and ecological distance to other stations. Estimates of epifauna abundance were also made. In the analysis an important distinction...
