The relationship of non-recovered rodent caches to the natural regeneration of ponderosa pine

Creator:: Saigo, Barbara Woodworth
Abstract:: Studies were conducted within a 12-mile radius of Camp Sherman, Oregon, in the Deschutes National Forest during the spring and summer of 1965 and the spring of 1966, with one follow-up visit in the summer of 1967. The feeding and foraging activities of Eutamias amoenus and Citellus lateralis were observed,...

The genetic regulation of sex-specific motorneurons by the doublesex gene in Drosophila melanogaster and the genetic characterization of an interaction with the sex determination hierarchy

Creator:: Larsen, DeLaine D.
Abstract:: The remodeling of the central nervous system (CNS) during metamorphosis in Drosophila melanogaster is a prime model system in which to study the genetic control of the sexual dimorphisms in the abdominal ganglion of the CNS. I have been using a P[tau-lacZ] enhancer trap line, 4.078, to label a segmentally...

Pheromonal mediation of reproductive behavior in the brown tree snake

Creator:: Greene, Michael John
Abstract:: In animals, reproductive behaviors serve to attract individuals together during the breeding season and to coordinate the behavioral and physiological states of individuals so that mating can successfully occur. In snakes, the various reproductive behaviors including courtship, mating, courtship inhibition, male combat and trailing are mediated primarily by pheromones. Pheromones...

Size variation and food habits of larval bullfrogs, Rana catesbeiana Shaw, in western Oregon

Creator:: Brown, Randall Errol
Abstract:: An investigation was made of the factors which cause differences in growth rates and transformation size of bullfrog tadpoles under natural conditions. Tadpoles and algal samples were collected from two.adjacent farm ponds of similar size during the eighteen months of the study. It was found that the tadpoles in one...

Determination of mode of death of John Day Merycoidodontidae (Oreodontidae) by populaton age structure analysis

Creator:: Brown, Melinda Elaine
Abstract:: Volcanic activity during the Tertiary has long been held responsible for the deaths and subsequent fossilization of the vertebrate populations of the John Day region in Oregon. Oreodonts as plains or savannah dwelling ruminant herbivores, were likely to have been subject to potential exposure throughout their lifetime to volcanic debris...

An experimental test of optimal outbreeding in the harpacticoid copepod Tigriopus californicus (Baker)

Creator:: Brown, Alice F.
Abstract:: Hypotheses concerning relative costs of inbreeding and outbreeding were evaluated for the harpacticoid copepod Tigriopus californicus, which inhabits high intertidal tidepools. Field studies indicate high variation in biotic and abiotic parameters among pools. These findings coupled with previous information about very low dispersal rates and local adaptations to individual pools...

Characterization of putative recognition components of echinoderm coelomic fluid: agglutinins in Strongylocentrotus purpuratus

Creator:: Pierce, Laura G.
Abstract:: Due to an interest in the evolutionary origins of vertebrate mechanisms of immunorecognition, researchers have frequently turned to deuterostome invertebrates as model organisms. The purple sea urchin, Strongylocentrotus purpuratus (Echinodermata: Echinoidea), was selected for this study of putative immunorecognition molecules in a deuterostome invertebrate. Hemagglutinins, molecules which agglutinate red blood...

Physiological alterations following severe hypoxic stress in two species of fresh-water fish

Creator:: Heath, Alan G.
Abstract:: Bluegill sunfish, Lepomia macrochirus, and cutthroat trout, Salmo clarki, were exposed to a rapidly declining oxygen tension for a period of time sufficient to just cause loss of equilibrium in the fish. During recovery from the stress, measurements of oxygen uptake, blood lactic acid, blood glucose, liver glycogen, muscle glycogen,...

The comparative histochemistry of the decapod antennal gland--esterases, phosphatases and glycogen

Creator:: Fuller, Eugene G.
Abstract:: The distributions of alkaline phosphatase, acid phosphatase, non-specific esterases, and glycogen were described for the antennal glands of the freshwater crayfish, Pacifastacus, and the marine crabs Cancer and Pugettia. Alkaline phosphatase is confined primarily to the luminal edge of the labyrinth in all of the above forms whereas acid phosphatase...
