The morphology and sexual maturation of Philometra americana Ekbaum, 1933 (Dracunculoidea:Philometridae)

Creator:: Carter, Richard Thomas
Abstract:: The female Philometra americana Ekbaum, 1933 is a common subcutaneous parasite of the starry flounder, Platichthyes stellatus (Pallas) of Yaquina Bay, Lincoln County, Oregon. Maturation of this worm produces noticeable red cysts subcutaneously between the fin and tail rays and similarly on the operculum. The gravid female penetrates the epidermis...

An histochemical study of the changing patterns of glycogen distribution in the uterus and extra-embryonic membranes of the golden hamster (Mesocricetus auratus Waterhouse)

Creator:: York, James Walter
Abstract:: This study deals with the histochemistry of the changing patterns of glycogen in the uterus and extra-embryonic membranes of the golden hamster (Mesocricetus auratus Waterhouse). The uterus and extra-embryonic membranes of the golden hamster representing days of gestation from six to term were stained with periodic acid-Schiff and Best's carmine....

A histochemical study of oogenesis in the sea urchin, Strogylocentrotus purpuratus

Creator:: Chatlynne, Louise Geller
Abstract:: Oögenesis in the sea urchin Strongylocentrotus purpuratus was studied by histological methods and by histochemical techniques for polysaccharides, lipids, and nucleic acids Urchins were collected at Yaquina Head, Oregon at regular intervals between April 1966 and March 1967. An attempt was made to correlate seasonal variations in the coastal water...

Effects of chronic coumestrol administration on female rats

Creator:: Chan, Elaine Chi-ling
Abstract:: The effects of coumestrol on the uterine weight, uterine fluid imbibition, uterine nucleic acid content, adrenal weight and body weight of female rats were studied. Daily doses of 20 micrograms of coumestrol per 0.1cc propylene glycol were administered subcutaneously to spayed rats following a seven day recovery period, for durations...

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 relationship between body size and metabolism in Lepomis macrochirus Rafinesque

Creator:: Behrisch, Hans Werner
Abstract:: Weight-specific oxygen consumption of intact bluegill sunfish was estimated in relation to body weight and temperature by the sealed jar method. The relationship between body weight and weight-specific oxygen consumption was represented by the equation: Y = aX[superscript b]⁻¹ in which Y is the weight-specific oxygen consumption, expressed as cc/kg/hr,...
