The response of animals to herbicide-induced habitat changes

Creator:: Borrecco, John Edward
Abstract:: The objectives of this investigation were to examine the changes in vegetation resulting from application of herbicides, and to study the effects of these vegetative changes on the abundance and composition of small-mammal populations, and on deer usage of treated and untreated plots. Three areas in western Oregon were selected...

Habitat relationships of birds and young-growth Douglas-fir in northwestern California

Creator:: Marcot, Bruce G.
Abstract:: Ninety-one species of birds were surveyed in grass/forb, early and late shrub/sapling, pole, and medium sawtimber stages of young-growth Douglas-fir in northwestern California; patterns of bird distribution and abundance were related to habitat conditions and even-age silvicultural treatments. Seven species (band-tailed pigeon, western wood pewee, dusky flycatcher, western bluebird, fox...

Interaction and behavior of the redside shiner (Richardsonius balteatus) and the steelhead trout (Salmo gairdneri) in western Oregon : the influence of water temperature

Creator:: Reeves, Gordon H.
Abstract:: Water temperature influenced interactions between redside shiners and juvenile steelhead trout (≥1+) in the field and the laboratory. Distribution of the two species within various habitats was determined in three streams with different water temperature regimes. The range of habitats occupied by trout in allopatry at cool temperatures and at...

Summer soil moisture dynamics in a young Douglas-fir plantation as influenced by three herbaceous weed communities

Creator:: Preest, David Stanley
Abstract:: The use of chemicals such as the triazines (especially atrazine) and mixtures of the triazines and 2,4-D or 2,4,5-T has become almost standard practice in some parts of the world for selectively controlling grasses and other herbaceous weeds to conserve moisture for and/or prevent the smothering of newly-planted conifers. In...

Patterns of interactive segregation in three species of sculpins (Cottus) in western Oregon

Creator:: Finger, Terry Richard
Abstract:: Species interactions and their effect on the use of habitat by benthic fishes were examined in a guild composed of Cottus perplexus, C. rhotheus, and C. beldingi in the Marys River above Philomath, Oregon, and in a constant environment provided by an artificial stream. In the Marys River system, the...

Effects of herbaceous weed control on young Douglas-fir moisture stress and growth

Creator:: Preest, David Stanley
Abstract:: Profitable, even-aged forest management depends on the early establishment and rapid growth of each new forest crop. These, in turn, require that the young trees have access to an adequate supply of native resources of moisture, nutrients and light. In Mediterranean-type climates, competition for soil moisture is the most serious...

Habitat classification and characteristics of small mammal and amphibian communities in beaver-pond habitats of the Oregon Coast Range

Creator:: Suzuki, Nobuya
Abstract:: During 1988-1989, stream habitat variables were compared between beaver-dam sites and unoccupied-stream sites to identify variables that may have been important for beaver (Castor canadensis) in selecting dam sites in the streams of the Drift Creek basin, Lincoln County, Oregon. Increasing valley floor width and grass/sedge cover and decreasing stream...

Controlling damage by ring-necked pheasants to sprouting corn in southwestern Idaho

Creator:: Helmich, Bryan T.
Abstract:: During the springs of 1988 1989, experiments were conducted to determine effective methods of controlling damage by ring-necked pheasants (Phasianus coichicus) to sprouting corn in southwestern Idaho. Plot evaluations (1988) failed to demonstrate the ability of Miller Hot Sauce Animal Repellent, Isotox Seed Treater (F), provision of alternate food, and...

Structure and Dynamics of Northeastern Pacific Demersal Fish Assemblages

Creator:: Gabriel, Wendy Louise
Abstract:: Regions of similar species composition and groups of demersal fish species with similar distribution patterns from Cape Flattery, Washington to Point Hueneme from 50-250 fm (93-460 rn) were defined based on results of an agglomerative cluster analysis of National Marine Fisheries Service Rockfish Survey data taken during the summer of...
