Ringtail (Bassariscus astutus) Survival, Home Range Size, and Rest Site Use in Southwest Oregon

Creator:: Somers, Lindsay N.
Abstract:: The ringtail (Bassariscus astutus) is a small, nocturnal, meso-carnivore that occupies mid-elevation forests in the southwest portion of Oregon. Ringtail are fully protected within Oregon, but a species of conservation concern as they may be vulnerable to habitat loss and fragmentation. Limited data exists regarding ringtail ecology in forested ecosystems,...

Fall Phenology, Movement, and Roost use of Little Brown Bats (Myotis lucifugus) and California Myotis (Myotis californicus) at Mount Rainier National Park

Creator:: Hansen, Michael
Abstract:: Little is known about the fall and winter ecology of hibernating bats in western North America. Filling knowledge gaps for these populations has become more urgent with the westward spread of the white-nose syndrome, a disease that infects bats during hibernation. Due to the thermal requirements of the fungal pathogen...

Assessing the Impacts of the Red Imported Fire Ant on First-Generation Monarch Butterfly Reproductive Success in a Texas Coastal Prairie

Creator:: Sutherland, Remy C.
Abstract:: In recent years, monarch butterfly (Danaus plexippus) populations have declined at an alarming rate resulting in an extensive conservation effort across the species’ migratory range. One hypothesis for declining populations is decreased reproductive success during spring migration. The eastern monarch population’s first annual generation occurs in the early spring when...

Cultural and Environmental Creencias (Beliefs) and Latin@ Outdoor Recreation in the Willamette Valley of Oregon

Creator:: Justiniano, Isabel
Abstract:: In Oregon, outdoor recreation activities have continued to grow in popularity, as has the overall Latin@ population of the state. With the continual population increase of this ethnic group, researchers have focused on understanding their outdoor recreation habits through an environmental justice lens. This includes accessibility, affordability, and other barriers...

Large Downed Wood as Post-fire Refugia for Terrestrial Salamanders in Pacific Northwest Forests

Creator:: Stephens, Paige N.
Abstract:: Climate change, wildfire, timber harvest, and land conversion alter the availability of downed wood in forests of the western United States. Numerous taxa rely on downed wood for temperature and humidity refugia, and downed wood may play a key role in enabling the persistence of climate-sensitive, low-vagility species like terrestrial...

Greater Sage-Grouse (Centrocercus urophasianus) Demographic Rates and Predator Communities in a Degraded Landscape in Modoc County, California

Creator:: Sink, Chelsea E.
Abstract:: The greater sage-grouse (Centrocercus urophasianus: hereafter; sage-grouse) population in Modoc County California is geographically isolated and has been subsidized by translocation to prevent inbreeding depression since 2005. Despite significant efforts to increase the population through translocations and habitat improvement by cutting encroaching western juniper (Juniperus occidentalis), only a single lek...

Hold the Plastic, Please: An Investigation of Sea Otter Exposure to Microparticles and Microplastics Using Scat and Diet Analysis

Creator:: Van Brocklin, Jennifer E.
Abstract:: Sea otters act as valuable indicators of ecosystem health and consume prey items that contain anthropogenic microparticles, including microplastics. Microplastic ingestion can exert a wide range of deleterious effects depending on the organism and plastic type. We investigated the ingestion of microparticles by wild sea otters (Enhydra lutris) in Alaska...

The Role of Trees and Thermal Refugia in Greater Sage-Grouse Brood Habitat Selection

Creator:: Dungannon, Tyler D.
Abstract:: It is well documented that greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) populations have been in decline throughout their range in the western United States. Currently, sage-grouse occupy approximately 56% of their historic distribution prior to European settlement. Numerous factors have been cited as potential causes for declining productivity and contraction...

The Impacts of Juniper Removal on Native Herbaceous Vegetation and Surface-Dwelling Invertebrates in the Sagebrush Steppe

Creator:: Haab, Kimberly A.
Abstract:: Understanding the effects of disturbance and restoration on a species’ habitat is essential for understanding the demographic rates and population trends observed in a species. Sufficient habitat provides the space and resources required for survival and successful reproduction, such as food availability, access to water, protection from predators, protection from...

The Breeding Ecology and Foraging Niche of Aleutian Terns (Onychoprion aleuticus) in the Kodiak Archipelago, Alaska

Creator:: Tengeres, Jill E.
Abstract:: The Aleutian tern (Onychoprion aleuticus) is a species of high conservation concern in Alaska due to large declines at known breeding locations since the 1960s. Due to the small population size and ephemeral behavior of this species on the nesting grounds, there is little basic biological information available and data...
