Neorickettsia helminthoeca in cell culture

Creator:: Noonan, William Edward
Abstract:: The etiologic agent of salmon poisoning disease was found to be Neorickettsia helminthoeca, although a second organism, the Elokomin fluke fever agent, may also be involved in other areas. Primary cultures of dog leucocytes were found to support the in vitro cultivation of Neorickettsia helminthoeca as were canine sarcoma 503...

Architecture, size, and reproduction in plants : a pollination study of Mertensia ciliata (James) G. Don

Creator:: Geber, Monica
Abstract:: I experimentally test the hypothesis that the potential for selfing increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible, profusely-flowering perennial. This follows from the premises that 1) pollen dispersal by pollinators between flowers is limited, and 2) individual pollinators, in this study bumblebees, will visit more flowers per...

An histochemical study of the changing patterns of glycogen distribution in the uterus of the early pregnant and lactating golden hamster (Mesocricetus auratus Waterhouse)

Creator:: Wicklund, Thomas Glen
Abstract:: This study deals with the histochemical identification of the changing patterns of glycogen in the uterus of the early pregnant and lactating golden hamster (Mesocricetus auratus Waterhouse). The uterus of the hamster representing days one through five of gestation, and one through ten, twelve, and fourteen of lactation, provided the...

An analysis of a population of snowshoe hares, Lepus americanus washingtonii Baird, in western Oregon

Creator:: Black, Hugh C., 1941-
Abstract:: The ecology of a population of snowshoe hares, Lepus americanus washingtonii, was studied in western Oregon from 1960 to 1962. Objectives were to obtain information to control hares, which frequently cause damage to coniferous reproduction in the region, and to compare the life history of this little-studied subspecies with others....

The oplophorid and pasiphaeid shrimp from off the Oregon coast

Creator:: Forss, Carl Albert
Abstract:: The 13 species of shrimps studied for this thesis were collected off the Oregon coast. The family Oplophoridae is well represented in this area. Five of the seven known genera were identified. Hymenodora frontalis, H. glacialis, and H. gracilis were described and further differentiating characters were illustrated. Other members of...

Histochemical study of some enzymes of the common liver fluke, Fasciola hepatica L.

Creator:: Panitz, Eric
Abstract:: Acid and alkaline phosphatase was localized histochemically in the intestinal epithelium and excretory duct respectively in fresh frozen sections of Fasciola hepatica. Polyphenol oxidase was localized in the vitellaria, vitelline ducts and egg-shells. The distribution and nature of esterases was examined histochemically. Acetyl-cholinesterase was observed in the tegument, neural ganglia,...

An analysis of vocalizations of the rufous-sided towhee Pipilo erythrophthalmus oregonus (Bell)

Creator:: Beltz, Joan Dunkel
Abstract:: The purpose of this study was to record on tape and to analyze the sonagrams of the complete repertoire of the vocalizations of the Rufous-sided Towhee, Pipilo erythrophthalmus oregonus. Meanings were assigned to a number of the calls. Sounds of nestlings, juveniles, and vocalizations connected with parental care were not...

Biological studies on the hemoflagellates of Oregon marine fishes and their potential leech vectors

Creator:: Burreson, Eugene Michael
Abstract:: Of 2,122 marine fishes belonging to 36 species collected in the vicinity of Newport, Oregon, 541 belonging to 8 species were infected with hemoflagellates. Four species of trypanosomes and three species of cryptobias were found in offshore fishes, but no hemoflagellates were observed in fishes from Yaquina Bay. Trypanosoma pacifica...

The ecology of Lepidurus apus in northern Utah and some limnological requirements for hatching

Creator:: Braswell, Audrey Lee Jr
Abstract:: A survey of the major bodies of water, temporary and perennial, in the region of Northern Utah revealed a limited distribution of the Notostraca. Lepidurus (Linn.), the only representative found, was restricted to a single temporary shallow lake. Dry Lake, in the southern end of Cache County. Dry Lake occupies...
