Evaluation of baits and baiting techniques for Belding's ground squirrels

Creator:: Sullins, George Lamont
Abstract:: Quantitative data concerning bait preference and bait application were collected for Belding's ground squirrels (Spermophilus beldingi) during February-July 1975. Bait materials tested for preference were crimped oats, oatgroats, whole wheat, barley, rolled wheat, rye, chopped lettuce, chopped apple, oatgroats + Rhodamine B dye, oatgroats + starch paste, oatgroats + Rhoplex...

Effects of ethyl mercury on some parameters of reproduction in ring-necked pheasants

Creator:: Christensen, Alan Gene
Abstract:: Prior to onset of the breeding season, a ration containing 18.4 mg/kg N-(Ethylmercuri)-p-toluene sulphonanilide was fed to 6 male and 16 female ring-necked pheasants (Phasianus colchicus). Birds receiving the mercury-treated ration were separated from the opposite sex. After receiving the mercury-treated ration for 0, 2, 4, 8, or 16 days,...

Systematics, variation, distribution, and biology of lampreys of the genus Lampetra in Oregon

Creator:: Kan, Ting Tien
Abstract:: Based on the number of velar tentacles and the form of longitudinal lingual laminae found in Lampetra (Entosphenus) t. tridentata and its closely related forms, the taxon Entosphenus should not be considered as a genus as commonly adopted, but, along with the taxa Lethenteron and Lampetra, should be regarded as...

Effects of dieldrin on the growth and development of steelhead trout

Creator:: Oregon State University. Agricultural Experiment Station, Shumway, Dean L., and Chadwick, George Grete
Abstract:: Experiments were conducted to determine survival, growth, and accumulation of HEOD (major component of dieldrin) in the tissues of steelhead trout (Salmo gairdneri) embryos, alevins, and fry exposed to dieldrin concentrations ranging from 0.012 to 52 ppb. The fish were held in specially designed exposure chambers provided with continuously renewed...

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...
