Cattle behavior and distribution on the San Joaquin Experimental Range in the foothills of central California

Creator:: Harris, Norman Rex
Abstract:: Small herds of cows were observed and spatially mapped over continuous twenty-four hour periods. Treatments were implemented that investigated the effect of water site and supplementation on animal distribution patterns. A series of six observation periods constituted each observation series. Observation series were repeated winter (January) and summer (July) for...

Twenty-five years of grazing research at Meadow Creek in the Starkey Experimental Forest and Range

Creator:: Walburger, Kenric
Abstract:: Three studies were conducted to evaluate different grazing systems on mixed conifer rangelands in eastern Oregon, and photo points and aerial photography was used to determine effects of 25 years of cattle grazing on stream channel changes and vegetation responses. The first study was designed to determine if grazing treatment...

Potential effects of the invasive grass Ventenata dubia on elk habitat selection within the Starkey Experimental Forest and Range

Creator:: Crum, Keren-happuch R.
Abstract:: The invasive annual grass ventenata (Ventenata dubia) has become an increasing problem within western rangelands. Forage quality of areas infested with ventenata is reduced as its high silica content makes it unpalatable to livestock and wildlife. In the following study, I examined whether significant presence of ventenata affects habitat use...

Multiple steroid and thyroid hormones detected in baleen from eight whale species

Creator:: Lysiak, Nadine S., Moore, Michael J., Hunt, Kathleen E., Robbins, Jooke, Seton, Rosemary E., Buck, C. Loren, and Torres, Leigh G.
Abstract:: Recent studies have demonstrated that some hormones are present in baleen powder from bowhead (Balaena mysticetus) and North Atlantic right (Eubalaena glacialis) whales. To test the potential generalizability of this technique for studies of stress and reproduction in large whales, we sought to determine whether all major classes of steroid...

Effect of Active Trailing Edge Motion Upon Airfoil Energy Harvester

Creator:: Strahl, Jordan D.
Abstract:: The application of a flapping foil with prescribed trailing edge motion to energy harvesting in a low reduced frequency (k = fc/U∞) regime was experimentally studied. The effects of the phase and amplitude of the applied trailing edge motion upon time-variant power extraction capability have been measured and are interpreted....

Herbage production on three vegetation types in the high desert of eastern Oregon

Creator:: Markgraf, Peter Marion
Abstract:: Objectives of this study were to determine differences in herbage production of three seral stages of three habitat-types. Field studies were conducted in 1967 and 1968 on the Squaw Butte Experimental Range. Twelve, 400-square-foot, paired exclosures were established in each habitat-type. Herbage was clipped from four, 48-squarefoot samples in one...

Influence of range improvement practices on composition, production, and utilization of Artemisia deer winter range in central Oregon

Creator:: Urness, Philip J.
Abstract:: Recent emphasis on range improvement of sagebrush-bunch-grass types in Oregon has underscored the need for better understanding of their importance to deer winter range management. The objectives of this study were to evaluate the impact of various sagebrush control practices on the composition, production, and utilization of deer forage plants...
