Endoparasitic gastropods of Puget Sound holothurians

Creator:: Tikasingh, Elisha Seujit
Resource Type:: Dissertation

Studies on the molluscan and fish hosts of the "salmon poisoning" fluke, Nanophyetus salmincola (Chapin)

Creator:: Gebhardt, Gary Alan.
Abstract:: This study¹ was undertaken: (1) to obtain information on the distribution of the snail, Oxytrema silicula, in three coastal rivers in Oregon, and the seasonal incidence of infection in these snails and in snails from an inland stream, with the cercariae of the trematode, Nanophyetus salinincola; (2) to follow cercarial...

The histopathological effects of larval trematodes on the hepatopancreas of Oxytrema siliqua (Gould)

Creator:: Porter, Clarence Alan
Abstract:: The histopathological and histochemical effects on the snail Oxytrema siliqua, caused by the larvae of Nanophyetus salmincola, have been studied. The parasite causes damage to the organ by increased pressure, active ingestion of the hepatic tubules, and by the increased burden placed upon the snail in disposing of the waste...

Creator:: Monroe, James E.
Resource Type:: Dissertation
Full Text:: . The taxonornic position of these snails is as follows: Class - Gastropoda Subclass - Pulnionata

Seasonal gametogenesis and egg laying in the prosobranch gastropods Nucella lamellosa, Nucella emarginata, Searlesia dira and Amphissa columbiana on the Oregon coast

Creator:: Seavy, Donald Keith
Abstract:: A 15-month field study was made on the reproductive cycles of the prosobranch gastropods Nucella lamellosa, Nucella emarginata, Searlesia dira and Amphissa columbiana on the Oregon coast. Amphissa columbiaria and Searlesia dira were collected from Boiler Bay, Nucella emarginata from Seal Rock and Nucella lamellosa from inside Yaquina Bay. All...

Heart rate, survivorship, oxygen consumption, and metabolic end product accumulations in the intertidal limpets Collisella pelta and Collisella digitalis in relation to desiccation and hypoxia

Creator:: Boese, Bruce Leon
Abstract:: The heart rate, oxygen consumption, survivorship, and 1-lactate accumulation were determined in the intertidal limpets Collisella pelta and Collisella digitalis in relation to laboratory desiccation at 15°C or 30°C. Water loss was computed as a percentage of total initial body water (wet weight - dry weight). Although water was lost...

Taxonomy and paleobiogeographic affinities of an early Middle Devonian (Eifelian) gastropod faunule from the Livengood quadrangle, east-central Alaska

Creator:: Blodgett, R. B.
Resource Type:: Dissertation

Pitfall and refuge trap sampling Linn Co March 2018-June2019

Creator:: Reich, Inga, Jessie, Casi, Ahn, Seung-Joon, Choi, Man-Yeon, Williams, Christopher, Gormally, Mike, and Mc Donnell, Rory
Abstract:: Numbers of carabid beetles, caterpillars, cranefly larvae and slugs collected from pitfall and refuge traps in ten Annual Ryegrass fields in Linn County, Oregon between March 23, 2018 and June 20, 2019. Given are details on sampling date, trap, size and sex (carabids only), weight (slugs only) and species (where...
