Soil arthropods in the Central Cascades : slash burning effects and biology of some species

Creator:: Estrada-Venegas, Edith G
Abstract:: Despite the recognized role of soil arthropod fauna on nutrient cycling and decomposition processes, many aspects of the effects of sylvicultural methods in forest ecosystems upon their biology remain poorly understood. The long term effects of prescribed fires on soil arthropods in forest ecosystems in the Pacific Northwest have never...

Ecuadorean soil arthropod distribution in native vegetation, pasture and cropland and a potato field with and without pesticides

Creator:: Núñez Terán, Verónica
Abstract:: In the past 10 years we have witnessed the beginnings of the study of soil ecology as a unified science, and the general realization by soil scientists, farmers, and land managers that many of the most important economic aspects of soil health are controlled by biological factors. This research focuses...

Occurrence of ectomycorrhizae on ericaceous and coniferous seedlings grown in soils from the Oregon Coast Range

Creator:: Smith, Jane E. (Jane Elizabeth)
Abstract:: Seedlings of Gaultheria shallon, Pseudotsuga menziesii, Rhododendron macrophyllum and Tsuga heterophylla were grown together in the greenhouse in soils from three young managed Douglas-fir forests in the Oregon Coast Range. The main objectives were 1 )to evaluate the ability of ericaceous plants and overstory conifers to share compatible mycorrhizal fungi...

Studies of the fungal endophyte Acremonium coenophialum in tall fescue

Creator:: Azevedo, Mark D.
Abstract:: Tall fescue is thought to have co-evolved with the fungal endophyte Acremonium coenophialum to form a mutualistic relationship. Endophyte-infected (EI) plants can have increased growth and survival when compared with endophyte-free (EF) plants. Responses to endophyte-infection vary and are host-genotype and fungal-biotype specific. Mechanism(s) by which endophyte-infection confers increased growth...

The effects of paclobutrazol and uniconazol on red clover seed production

Creator:: Silberstein, Thomas B.
Abstract:: Excessive growth by red clover, Trifolium pratense L., grown for seed interferes with maximum seed production and harvest in Oregon's Willamette Valley. This study was conducted during 1986 and 1987 on red clover cv. Kenland to determine if plant height and dry matter production could be inhibited and seed yields...

Response of Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) to defoliation of understory grasses and drought

Creator:: Purrington, Teal Mackenzie
Abstract:: Water potential, leaf conductance, growth, nitrogen content, and seedling survival of Wyoming Big Sagebrush (Artemisia tridentata ssp. wyomingensis) following defoliation of the herbaceous understory were assessed during two growing seasons. Precipitation was 107% and 63% of the long-term mean (283 mm) in 1989 and 1990, respectively, which presented an opportunity...

Crop and tree response to planting patterns in alley cropping systems

Creator:: Seiter, Stefan
Abstract:: Growing trees as a green manure crop together with an annual food crop is a new technology for farmers in Oregon. To promote farmer participation and to acquire a broad knowledge of the processes involved in species interactions, three feasible alley cropping and two sweet corn monocrop planting patterns were...
