Detecting Fish Vocalizations in American Samoa Using Machine Learning

Creator:: Munger, Jill
Abstract:: A deep neural network was developed and trained to identify the sounds of pomacentrids (damselfishes) in the National Park of American Samoa. Four years of continuous, passive acoustic data were recorded by a single stationary hydrophone. Deep neural networks enable the full utilization of such large datasets by automating laborious...

New discovery leads to a whole new meaning of “trash fish”

Creator:: Chione, Andrew
Abstract:: This paper is an assignment for my Ichthyology class at Oregon State University. I was tasked with creating a new fish species that is scientifically possible and telling a fictional story of its discovery.

PBDEs/Methylmercury and Immune Function in Non-Stranded Male California Sea Lions (Zalophus californianus) : A Literature Review

Creator:: Manon-Ferguson, Ameyalli I.
Abstract:: A literature review for a research project being done in partnership with the Oregon Department of Fish and Wildlife and the Columbia River Intertribal Fish Commission, which will look at non-breeding California sea lion males in the Columbia River Basin that have been preying on migratory salmon. This will be...

Variation of the Trowbridge's shrew (Sorex trowbridgii) diet across forest types in the Oregon Cascades

Creator:: Yates, Margaret E.
Abstract:: Investigating the insectivorous diet of the Trowbridge’s shrew (Sorex trowbridgii) across forest types can illustrate how forest management affects biotic communities. I used DNA metabarcoding methods with ANML primers to identify stomach and intestines contents from shrews caught in pitfall traps in the HJ Andrews Experimental Forest (HJA) and Willamette...

Assessing variation in coyote (Canis latrans) diet across three sagebrush steppe sites with different levels of juniper encroachment

Creator:: Kendall, Zachary D.
Abstract:: Juniper (Juniperus spp.) encroachment into the sagebrush steppe ecoregion is one of the main causes of sagebrush degradation and can alter the understory vegetative community by outcompeting native shrubs and grasses, which reduces the available forage and cover for small mammals. Coyotes (Canis latrans) are generalist, omnivorous predators in the...

Influence of Soil Texture on Carbon Storage of PNW Coastal Blue Carbon Ecosystems

Creator:: Fox, Conner S.
Abstract:: Coastal blue carbon ecosystems offer a variety of important ecosystem services, including exceptional rates of carbon sequestration and long-term carbon storage. Because these ecosystems disproportionately influence global carbon cycling, understanding their soil characteristics may help guide long-term climate change mitigation and adaptation strategies. Recently, Kauffman et al. (2020) observed the...

Effects of nesting waterbirds on nutrient levels in mangroves, Gulf de Fonseca, Honduras

Creator:: McFadden, Tyler Neal
Abstract:: Mangroves provide numerous ecosystem services, including biodiversity values such as nesting sites for piscivorous waterbirds. High concentrations of pisicivoirous birds are hypothesized to affect ecosystem dynamics, yet few studies have examined their effects in mangroves. We examined the effects of nutrient enrichment by colonial waterbirds at a mangrove rookery in...

Diversity and composition of mammal and bird communities in northern Pantanal, Brazil

Creator:: Coe, Lauren E.
Abstract:: The Pantanal is one of the largest wetlands in the world, covering 195,000 km2 across Brazil, Bolivia and Paraguay. It has a unique annual flooding regime with the majority of land being completely inundated during the wet season, which provides important habitat for threatened species such as jaguars (Panthera onca)...

Surfacing Behavior of Juvenile Loggerhead Sea Turtles (Caretta caretta) in North Carolina

Creator:: Patton, B. Wren
Abstract:: Sea turtles are endangered species that can be censused with aerial surveys, but the number of turtles in an area must be extrapolated to include animals that are submerged. Twenty-one satellite tags were attached to juvenile loggerhead sea turtles (Caretta caretta) in North Carolina. I analyzed surfacing and dive behavior...

Genetic and morphological evidence suggests cryptic speciation within the Torrent Sculpin, Cottus rhotheus, across the Pacific Northwest

Creator:: Nicholas, Benjamin P.
Abstract:: Dwelling on the bottom of large rivers to high alpine streams, freshwater sculpins (genus Cottus) occur in high densities across the Pacific Northwest, with 21 currently recognized species found in the Pacific Northwest. Sculpin fill many ecological roles, with some species serving as important prey sources, and others competing with...
