Immunological perspectives of a host-parasite system : studies on the humoral and cellular components of Biomphalaria glabrata, New World host for Schistosoma mansoni

Creator:: Boswell, Carl A.
Abstract:: The host snail Biomphalaria glabrata and the parasitic trematode Schistosoma mansoni are valuable subjects for studies evaluating and defining immunological parameters that determine the outcome of individual host-parasite encounters. In this thesis, both soluble and cellular components of the snail's hemolymph were examined to gain insight into the basis for...

Larval settlement and juvenile group dynamics in the domino damselfish (Dascyllus albisella)

Creator:: Booth, David J. (David John), 1958-
Abstract:: Patterns of settlement of larvae and population dynamics of juveniles are poorly known for coral reef fishes. During 1987 to 1989, I studied these phenomena in the domino damselfish (Dascyllus albisella), a species endemic to the Hawaiian Islands. Larvae settle onto branching coral heads as new recruits (10-15 mm in...

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...

Chronobiology of garter snakes : environmental and hormonal mechanisms mediating hibernation and reproduction

Creator:: Lutterschmidt, Deborah I.
Abstract:: Most vertebrates exhibit seasonality in many life history traits. Such seasonal rhythms are temporally organized via the transduction of environmental cues (e.g., photoperiod, temperature) into appropriate endocrine signals. However, among ectothermic vertebrates that undergo continuous winter dormancy, temperature is the only environmental cue available for synchronizing seasonal rhythms. Most intriguing...

Evolution of sodefrin precursor pheromones in salamandrid newts

Creator:: von Reis, Martha
Abstract:: An ancient pheromonal signal is found in aquatic courting salamandrids and terrestrial courting plethodontids, two highly divergent salamander families. In the aquatic courting salamandrids Cynops pyrrhogaster and C. ensicauda, the decapeptide sodefrin is cleaved from a larger 189 amino acid Sodefrin Precursor Factor (SPF) protein and released from a gland...

Stress and reproduction in male garter snakes

Creator:: Moore, Ignacio T.
Abstract:: Animals respond to stressful situations with increases in plasma levels of glucocorticoid stress hormones. These hormones originate from the adrenal cortex in response to stimulation of the hypothalamic-pituitary-adrenal axis. Glucocorticoids (corticosterone in reptiles) function to mobilize energy and suppress unnecessary functions until the stress passes. Among these immediately unnecessary functions...

The role of luteinizing hormone-releasing hormone in the neuroendocrine control of seasonal reproduction in male rough-skinned newts, Taricha granulosa

Creator:: Zoeller, Robert T.
Abstract:: One hypothesis proposed to explain how the endocrine system controls reproductive cycles in seasonally breeding animals is that the hypothalamus undergoes seasonal changes in sensitivity to negative feedback by gonadal steroids. The result is seasonal changes in the secretion of luteinizing hormone-releasing hormone (LHRH) and gonadotropin secretion. The present experiments...

Blood calcium and phosphorus perturbations in rainbow trout (Salmo gairdneri) and coho salmon (Oncorhynchus kisutch) : some correlates of physiological stress

Creator:: Adams, Brett Alan
Abstract:: Changes in blood calcium and phosphorus concentrations were characterized for rainbow trout (Salmo gairdneri) and coho salmon (Oncorhynchus kisutch) following intense exercise or exposure to suspended volcanic ash or topsoil. Significant elevations in blood calcium and phosphorus accompanied exercise-induced acidemia in both S. qairdneri and O. kisutch. These elevations persisted...

Resource allocation in four syntopic species of marine diving birds

Creator:: Scott, James Michael, 1941-
Abstract:: During 1969-1971 I studied patterns of resource allocation and behavioral interaction among Brandt's Cormorants, Pelagic Cormorants, Common Murres and Pigeon Guillemots in the area of a breeding colony on Yaquina Head on the central Oregon coast. Extensive studies of the breeding colony were combined with detailed observations of the distribution,...
