Stomach Analysis of Top Aquatic Predators in a Headwater Stream Network

Creator:

Ain, Najma

Abstract:

Top predators play important roles in regulating communities and ecosystem processes in freshwater ecosystems. In the headwater stream network, it is crucial to understand the interspecific interaction between multiple predators. In Oregon forested ecosystems, Coastal Giant Salamander (Dicamptodon tenebrosus) and cutthroat trout (Oncorhynchus clarkii) are the top predators in many...

Ingestion of Microplastics in the Juvenile Black Rockfish (Sebastes melanops) from Oregon Coastal Sampling Sites

Creator:

Arnold, Madison A.

Abstract:

Microplastics (<5mm) are a ubiquitous environmental pollutant that have the potential to cause significant harm in many fish species. Therefore, understanding the quantities at which they are being consumed by living organisms is crucial for characterizing risk. There are currently gaps in the microplastic literature regarding microplastic data from finfish...

How sweet is the land? Modeling caloric landscapes for tropical hummingbirds

Creator:

Birkett, Christina Nozomi and Birkett, Nozomi Fukui

Abstract:

Pollination is a critical ecosystem function for sustaining biodiversity. However, pollinators and the services they provide are threatened by landscape-altering anthropogenic activities across the globe. Habitat loss and fragmentation, introduction of invasive species, chemical use, and urbanization have been shown to impact pollination. Pollinator foraging behavior is thought to be...

Carbon isotopes show snowpack acts as a valuable moisture subsidy to mountain forests in the Oregon Cascades

Creator:

Ratcliff, Christopher J.

Abstract:

This study examines climatological influences, particularly that of snowpack, on tree growth and stable carbon isotope discrimination (Δ¹³C) from ~1980 to 2013 at two sites located in the upper reaches of the McKenzie River watershed of the Oregon Cascade Mountains. We tested the use of Δ¹³C values from latewood, corroborated...

Wildfire Severity Has a Minimal Influence on Pollen Diversity Used by Developing Mason Bees (Osmia lignaria) in Mixed Conifer Forest

Creator:

Bell, Nicole C. S.

Abstract:

Native bees are critically important organisms that support biodiversity and crop production via their pollination services. Wildfires in temperate conifer forests can increase bee abundance and flowering plant density due to increased light exposure, but little information is available regarding how wildfire severity influences provisioning to bee offspring, which is...

Determining the Onset of Reproductive Capacity in Free-Roaming, Unowned Cats

Creator:

Bohrer, Ellie

Abstract:

The purpose of this thesis was to determine if an underlying biological cause exists for the exuberant reproductive success in free-roaming unowned (FRU) cats. The hypothesis for this thesis was that FRU tom and queen cats have reproductively adapted to man-made sterilization efforts by lowering the age at which they...

Interactive Science Learning Program for Elementary School Students at Beazell Memorial Forest in Philomath, OR

Creator:

Sweetkind, Reid Smith

Abstract:

The FOCUS (Forest, Organisms, Creeks yoU Study) field trip program was developed to provide elementary students in Benton County, Oregon with a hands-on, environmental education experience at Beazell Memorial Forest. Students participated in activities dedicated to specific habitats and organisms found at Beazell that built upon their learning at school....

The Biogeography of European Bats

Creator:

Olson Dougan, Jackson Martin

Abstract:

Understanding species distributions temporally and spatially will facilitate effective conservation efforts and catalyze informed environmental management decisions. The predicted distributions of 31 species of European bat (Mammalia: Chiroptera) were mapped across Europe using species presence records and environmental data from 72 environmental variables (annual mean temperature, precipitation, etc.). In order...

Under the Sea: An evaluation of the establishment and continued effectiveness of the Galápagos National Park and Marine Reserve in Ecuador

Creator:

Asson, Danielle C.

Abstract:

Conservation of natural resources has become a new watchword of the scientific community. While many terrestrial ecosystems are well protected, marine ecosystems have only recently come to the forefront. Marine Protected Areas (MPAs) have been introduced as a means of protecting biodiversity, commercial stocks, and ecosystem services. There are many...
