The physiological response of juvenile steelhead (Oncorhynchus mykiss) to prolonged heat stress was examined by exposing replicated groups of fish to 25 consecutive days at 15°C, 23°C, and 25°C followed by a 55 day recovery period at 15°C. We found that at temperatures ≥25°C, steelhead consumed significantly less food per...
Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...
Non-coding ribonucleic acid (ncRNA) is of interest for its diverse roles in cell and viral biology. RNA molecules vary greatly in terms of size, structure, and function. In recent years, the modification of existing RNA structures has been used for biochemical methods of enormous impact including CRISPR and RNAi methods....
Despite growing efforts to recruit individuals from diverse backgrounds, natural resources fields, including marine aquatic and fisheries science, do not reflect the diversity of the United States. This dissertation utilized three studies to explore underrepresentation in marine, aquatic, and fisheries sciences by examining career influences, experiences, and perspectives at different...
The role that anthropogenic and natural habitats in estuaries play in long-term population trends for Oregon’s nearshore marine fishes is poorly understood, in part due to limited temporal sampling. One important nearshore marine group is northeastern Pacific rockfishes (Sebastes spp.), which are highly diverse, with around 96 documented species, and...
Studies of avian movement ecology afford essential insights regarding species' life histories, population dynamics, habitat and resource requirements, and other ecological relationships. While it is widely recognized that events in different stages of the annual cycle have important implications for processes in avian ecology, evolution, and conservation, challenges associated with...
Arctic cod (Boreogadus saida) is an ecologically significant species that plays a critical role channeling energy throughout the Arctic marine food web. Arctic cod is uniquely adapted to occupy ice edge habitats, however, a basic understanding of its larval physiology and habitat requirements is lacking due to widespread sea ice...
Atmospheric carbon reduction is arguably the most crucial facet among efforts to mitigate climate change. The Fifth International Panel of Climate Change report emphasizes a worldwide goal of maintaining global temperature elevation less than 1.5°C above pre-industrial temperatures. This report also acknowledges without the proper utilization of counteractive emission strategies...
Selecting locations for large energy facilities represents a land use dilemma: The beneficiaries of such facilities often are not the ones to suffer from adverse local impacts. As a result, it is not uncommon for local opposition groups to form in response to such proposals, and although opportunities for public...
