Influence of dissolved oxygen concentration and swimming velocity on food consumption and growth of juvenile Coho salmon

Creator:: Hutchins, Floyd E.
Abstract:: Laboratory studies were conducted on the food consumption, growth, and bioenergetics of juvenile coho salmon (Oncoynchus kisutch) held at various swimming velocities and dissolved oxygen concentrations at 15 C. Food consumption and growth of salmon fed to repletion on housefly larvae (Mus domesticus) were reduced by increasing activity at and...

The effects of prescribed burning on small mammal communities in Lava Beds National Monument, California

Creator:: Frenzel, Richard Wilmarth
Abstract:: The effects of prescribed burning on the abundance, species composition, and reproduction of small mammals were studied over a one year period. Two burn areas were studied, one in sagebrush/ bunchgrass and one in cheatgrass. The short-term effects were studied using monthly mark-recapture trapping on two treatment and two control...

Roosevelt elk habitat use in the Oregon Coast Range

Creator:: Witmer, Gary William
Abstract:: Daily and seasonal habitat use by Roosevelt elk was investigated in the Oregon Coast Range on managed, public forestland. Over 3,700 locations of 6 radio-collared cow elk were recorded during 12 consecutive months. Two elk formed part of a north band and 4 elk were part of a south band....

Interactions between grizzly bears and hikers in Glacier National Park, Montana

Creator:: Jope, Katherine Louise McArthur
Abstract:: Behavior of grizzly bears (Ursus arctos) toward people was studied by examining hikers' reports of grizzly bear observations and by intensively observing grizzlies in an area of Glacier National Park that was heavily used by day-hikers. Of concern were the apparent habituation of grizzly bears to people in the study...

Trophic adaptations and relationships of rockfishes (Sebastes spp.) of Oregon

Creator:: Pequeño, Germán E.
Abstract:: A comparative analysis of structures related to capture and processing of food, in 624 specimens belonging to 31 species of Sebastes of Oregon was made. The structures studied were the following: the tooth-bearing bones (premaxillary, dentary, vomer, palatine); the maxillary, angular, articular, parasphenoid and glossohyal bones; the lower limb of...

Ecology of woody riparian vegetation in tributaries of the Upper Grande Ronde River basin, Oregon

Creator:: Lytjen, Danna J.
Abstract:: Two studies on Catherine Creek and Meadow Creek of the Upper Grande Ronde River basin, quantified several physical and biotic influences on woody riparian community composition and structure. The Catherine Creek study examined the association of woody riparian species with elevational and geomorphic gradients. The Meadow Creek study examined the...

Benthic biological invasions in two temperate estuaries and their effects on trophic relations of native fish and community stability

Creator:: Castillo, Gonzalo C.
Abstract:: The extent of biological invasions, their role on the feeding of native fishes and their impact on community stability were investigated in Alsea Bay and Yaquina Bay, two estuaries on the central Oregon coast, USA. Most nonindigenous species (NIS) introduced in these intermediately invaded estuaries are considered byproducts of culturing...
