Leadership behavior and foraging strategies of a herd of Roosevelt elk inhabiting the Oregon Coast Range

Creator:: Marquez, Monica
Abstract:: A cow-calf herd of Roosevelt elk (Cervus elaphus roosevelti) resident to Indian Creek Research Center (ICRC), Oregon was observed June-August, 1985 and March-August, 1986. Cows at ICRC reproduced in alternate years; cows with calves led the herd a significantly greater number of times than cows without calves (1985, P <...

A comparison of four methods used in determining the diets of large herbivores

Creator:: McInnis, Michael Lindsay
Abstract:: Esophageal fistulation, stomach content analysis, fecal analysis, and ocular-estimate-by-plot are four of the most publicized methods of determining the diets of large herbivores. The principal objective of this study was to compare the relative values of each of these methods based upon information collected from bi-fistulated (esophageal and rumen) sheep...

Evaluation of Rhizobium strains with three Mediterranean forage legumes for biological nitrogen fixation

Creator:: Streeter, Donald J.
Abstract:: Centuries of continuous grain cropping in northern Africa have reduced N levels in soils to a degree such that agricultural production is now largely dependent upon nitrogen fertilizer. Through the identification of highly effective legume and Rhizobium strain combinations, the production of protein-rich livestock forage and green manure can be...

Morphological variability and seed dormancy of Amelanchier (Rosaceae) grown in Oaxaca, Mexico

Creator:: Cruz-Cruz, Efrain
Abstract:: The purpose of this research was to determine whether hybridization between Amelanchier denticulata. (H.B.K.) Koch and Amelanchier nervosa (Decaisne) StandL occurs in Oaxaca, Mexico, and to evaluate components of yield and germination characteristics and seed dormancy of Amelanchier denticulata. Amelanchier nervosa and Amelanchier denticulata samples and morphological characters were used...

Ecological relationships between cervid herbivory and understory vegetation in old-growth Sitka spruce-western hemlock forests in western Washington

Creator:: Happe, Patricia Jenkins
Abstract:: The relationships between black-tailed deer (Odocoileus hemionus columbianus) and Roosevelt elk (Cervus elaphus roosevelti) herbivory and understory vegetation in unmanaged forests in Olympic National Park were studied from 1985 - 1989. From 1985 to 1986 I studied the impact of cervid exclusion on shrub, fern, and forb forage quality, tannin...

Effects of vegetation control, stock size, fertilization, and soil moisture on the shoot and root development of Douglas-fir seedlings

Creator:: Burney, Owen T.
Abstract:: The overall purpose of this study was to examine the root and shoot development of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings at two distinct time periods in seedling establishment (after I and 3 growing seasons) in response to fertilizer, stock size, vegetation control, and soil moisture treatments. Two separate experiments...

Determining options for agroforestry systems for the rehabilitation of degraded watersheds in Alemaya Basin, Hararghe Highlands, Ethiopia

Creator:: Bishaw, Badege
Abstract:: Deforestation, accelerated soil erosion, and land degradation are serious problems in Ethiopia. The uncontrolled removal of natural forests, demographic pressures and cyclical drought has aggravated the situation, resulting in massive environmental degradation and a serious threat to sustainable agriculture and forestry. To overcome these problems efforts have been made to...
