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,...

Western Stemmed Tradition Technologies and Faunal Remains from a Terminal Pleistocene Pit Feature at the Cooper’s Ferry Site

Creator:: Paulson, Kirsten
Abstract:: Excavation of pit feature 110 (F110) at the Cooper’s Ferry site (10IH73) in central Idaho provides a unique snapshot of the domestic lifeways associated with the Western Stemmed Tradition (WST). Analysis was conducted of the F110 assemblage to better understand the function F110 served. The contents of F110 include Canis...

Structure and Dynamics of the Canine (Canis familiaris) Nasal Microbiome

Creator:: Knorr, Elizabeth
Abstract:: The diverse community of bacteria living within and on host organisms, known as the microbiome, has an important role in maintaining host health. Dysbiosis, known as a change in the healthy community of the microbiome, has been associated with a number of diseases across host organisms and body sites including...

How competitive are iconic competitors? Testing resource partitioning in Great Basin chipmunks

Creator:: Ormand, Elora J.
Abstract:: Competitive exclusion is a key concept in ecology describing the exclusion of one species by another from access to a limited resource. Competitive interactions between chipmunk species in the Great Basin, documented by James Brown in 1970, are often used as a textbook example of competitive exclusion. Whether competitive interactions...

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...

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)...

Diel Rest Structure Selection and Multiscale Analysis of Pacific Marten Resting Habitat in Lassen National Forest, California

Creator:: Tweedy, Patrick J.
Abstract:: Forests in the western United States have changed drastically over the past 150 years given a long history of utilization (harvest and grazing) and associated fire exclusion. These actions have altered the composition and structure of these forests as well as affected ecosystem function. Current policies for federal land management...

Habitat Use of Female Columbian Black-tailed Deer in Western Oregon

Creator:: Schrautemeier, Timothy J.
Abstract:: Columbian black-tailed deer (Odocoileus hemionus columbianus) are important economically, ecologically, and culturally as an indigenous species in western Oregon. Oregon Department of Fish and Wildlife (ODFW) observed declines in black-tailed deer populations since the late 1980’s and attributes these declines to reduction in quality and availability of habitat, following the...

Diet overlap by DNA metabarcoding of mule deer, elk, and cattle in ponderosa pine forest of eastern Oregon

Creator:: Faber, M. Kate
Abstract:: Millions of acres of rangeland in the western U.S. is shared habitat by elk (Cervus canadensis), mule deer (Odocoileus hemionus), and cattle (Bos taurus). Potential competition between these ungulates for the same forage species can be understood from their diet composition. I used DNA metabarcoding methods with trnL primers to...
