A root-lesion nematode, Pratvlenchus penetrans, was determined to
be a major component of peppermint stand decline in Western Oregon.
Regression analysis showed that P. penetrans root densities in August
were negatively correlated (P=0.01) with yield, while soil densities
in August and root and soil densities in April were poorly correlated...
Objectives:
To evaluate the impact of the ring nematode, Mesocriconema xenoplax on the physiology and productivity of phylloxera-resistant grape rootstocks as a basis for recommending rootstocks in the Pacific Northwest. Specific objectives for 2006:
Spring: Inoculate soil with AMF and M. xenoplax. Plant vines.
Growing season: Monitor plant growth, gas...
In his works, A Portrait of the Artist as a Young Man (1916) and Ulysses
(1922), James Joyce demonstrates what he perceives to be the paralyzing effects of
those institutionalized religions that sit at the center of cultures. Drawing on Michel
Foucault's analysis of institutional dressage as well as his...
Procedures are developed for integrating short-term,
area-based plans with long-term, strata-based harvest
schedules. These procedures were tested on a 4000 hectare
tract of forest land in British Columbia. It is shown that
a combination of these two approaches to forest planning
provides a spatially feasible short-term solution that is
also...
One of the most commonly encountered plant-parasitic nematodes in eastern Washington Vitis vinifera vineyards is Meloidogyne hapla; however, limited research exists on the impact of this nematode on V. vinifera. The objectives of this research were to determine the impact of M. hapla on Chardonnay and Cabernet Sauvignon vine establishment...
Natural resource educators are beginning to appreciate that formal critical thinking and ethical reasoning skills are not only important but absolutely necessary tools for the 21st century natural resource professional (both scientist and manager). However, given a historic lack of formal ethical reasoning within natural resource curricula combined with the...
Parmelina quercina is a well-studied foliose macro-lichen found on rocks and trees in the Northern Hemisphere. Recent studies support multiple species within P. quercina based on material from Europe, North America and western Asia. The identities of Parmelina quercina s.lat. reported from eastern Asia and Alaska remain unknown. We compared...
