Defining micro-habitat relationships for juvenile black rockfish, Sebastes melanops

Creator:: Mann, Marion E.
Abstract:: The functioning of marine habitats needs to be understood in the context of the ecological relationships and associations between organisms and the physical and biogenic environment they inhabit. Thus, it becomes important to explore and define habitat features which contribute to these relationships and which are important in the life...

Formulation of a synthetic seawater for bioassays with Mytilus edulis embryos

Creator:: Courtright, Robert Carl
Abstract:: Commerical preparations and published formulations using reagent chemicals for seawater substitutes were not biologically acceptable to Mytilus edulis embryos, in that calcification did not occur. When Leslie coarse hide salt was used as the source of NaCl for literature formulations, most formulas provided some success in the development, growth and...

Factors influencing spawning site choice by female Garibaldi, Hypsypops rubicundus (Pisces: Pomacentridae)

Creator:: Sikkel, Paul C.
Abstract:: The garibaldi, Hypsypops rubicundus, is a sexually monochromatic pomacentrid found in rocky subtidal areas of Southern and Baja California. During the spawning season, males attempt to attract females to a nest of red algae located within individually defended territories. Females were observed to enter the nests of several males before...

Structural Variations of Headwater Stream Food Webs Along Geophysical Gradients at the HJ Andrews Experimental Forest

Creator:: Zatkos, Lauren E.
Abstract:: The structure of food webs and how they relate to community stability has been an important debate in ecology. Specifically, predictability of web shape and how it influenced by surrounding landscapes is one of the main goals of such discussions. Headwater streams provide a study template that is of interest...

Gene expression in the liver of rainbow trout, Oncorhynchus mykiss, during the stress response

Creator:: Momoda, Tracey S.
Abstract:: The extent to which responses to stress are maladaptive or adaptive to the long-term survival of fish remains to be better understood. The aim of this study was to identify differentially expressed genes in the livers of rainbow trout, Oncorhynchus mykiss, responding to an experimental stressor. Gene expression responses were...

Growth of juvenile Pacific oysters, Crassostrea gigas (Thunberg) and Manila clams, Tapes japonica (Deshayes) in effluent from salmon-macroalga polyculture system

Creator:: Diaz, Maria Elena, 1958-
Abstract:: Experiments were carried out in fall and winter, 1990 and spring and summer, 1991 , to determine growth and mortality of juvenile Pacific oysters {Crassostrea gigas) in effluent from cultured coho salmon {Oncorhynchus kisutch) , and effluent from salmon in which the red macroalga Palmaria mollis was cultured. Ambient sea...

Responses of juvenile coho salmon and larval lamprey to instream habitat restoration in a Pacific Northwest stream

Creator:: Gonzalez, Rosalinda
Abstract:: Large wood has been utilized in many restoration projects to improve in-stream habitat in the Pacific Northwest for salmon. However, the benefits of this practice remain the subject of ongoing debate and evaluation of these projects has scarcely been done for non-salmonid species such as lamprey. In this study we...

The Effect of Group Size on Individual Roles and the Potential for Cooperation in Group Bubble-net Feeding Humpback Whales (Megaptera novaeangliae)

Creator:: Mastick, Natalie
Abstract:: Group foraging is observed in many species as a means to increase the ability of members of the group to find and exploit patchy prey. Group foraging can be exhibited in a number of different contexts based on the relationships between the participants, including by-product mutualism. One variant of by-product...

Spatio-temporal Patterns and Ecological Drivers of Harbor Porpoise (Phocoena phocoena) off the Central Oregon Coast, USA

Creator:: Holdman, Amanda
Abstract:: The marine environment is under increasing pressure from human activities worldwide, particularly in coastal waters, creating a need to better understand fine-scale distributions of highly mobile species that occur in the area, as they are frequently most threatened. Harbor porpoise (Phocoena phocoena) occur frequently in Oregon’s nearshore habitat, but due...

Habitat segregation of two ambystomatids in mountain ponds, Mount Rainier National Park

Creator:: Brokes, Brendan J.
Abstract:: Ambystoma macrodactylum (long-toed salamander) and A. gracile (northwestern salamander) are two common salamander species occupying key trophic positions in mountain ponds of Mount Rainier National Park. The objective of this research was to document and evaluate the distributions and abundances of the two species, relative to habitat characteristics of ponds...
