Sperm acrosome associated 3 protein expression and antigenicity in horses

Creator:: Cozzi, Brynley C.
Abstract:: Sperm acrosome associated 3 protein (SPACA3) is a unique, intra-acrosomal, conventional-type lysozyme-like protein of mammalian spermatozoa. SPACA3 is present in all stages of ovarian follicles and is localized to granulosa cells and ooplasma in humans, mice, cows, dogs, and cats. The objective of this study was to determine if equine...

Creating Useful and Usable Climate Tools for Sagebrush Land Management Through Scientist and Manager Collaboration

Creator:: Brown, Melanie
Abstract:: The sagebrush ecosystem, home to numerous plant and animal species including big sagebrush (Artemisia tridentata) and the endemic greater sage-grouse (Centrocercus urophasianus), has endured fragmentation and degradation of both quantity and quality due to the cumulative and synergistic relationships between an abundance of individual disturbances including grazing, invasive annuals and...

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...

Effects of Fuel Reduction Treatments on Surface Fire Behavior in Juniper Woodland Ecosystems

Creator:: Williams, Claire L.
Abstract:: Juniper (Juniperus spp.) woodlands are native but expanding ecological communities that were historically limited by the natural fire return interval of the sagebrush (Artemisia spp.) steppe. These woodlands are often a mix of pinyon pine (Pinus spp.) and juniper that have increased significantly over the last century. This expansion has...

Exotic Species Success in Fire- and Harvest-Disturbed Forest Sites in Southwest Oregon

Creator:: Pearce-Smith, Sarabeth
Abstract:: Invasive plant species are a significant concern in Oregon’s forests, particularly in early-seral sites. Early-seral forests are generated by severe disturbances such as fire or timber harvest, and persist until canopy closure. They are vulnerable to invasion because they have abundant resources, and are important because they provide unique resources....

Lamb growth and pasture production in agrivoltaic production system

Creator:: Andrew, Alyssa C.
Abstract:: Grasslands and croplands located in temperate agro-ecologies are ranked to be the best places to install solar panels for maximum energy production. Therefore, agrivoltaic systems (agricultural production under solar panels) are designed to mutually benefit solar energy and agricultural production in the same location for dual-use of land. However, both...

Mixed-Conifer Stands of the Deschutes National Forest : A Brief History

Creator:: Rogan, Claire C.
Abstract:: In an effort to qualify the historical management and its effects on current stand structure, historical records, literature of the inter-mountain West, and current observations were utilized to paint a picture of the Deschutes National Forest. Stand data were collected for the Deschutes during the summers of 2009 and 2010....

The Impact of Income Generating Programs at Tarangire National Park, Tanzania

Creator:: McDowell, Dylan
Abstract:: The newest pilot project at Tarangire National Park (TAR) is Income Generating Programs (IGP) where community groups organize themselves around an activity that earns income. TAR initiated the project by paying for ten members from each of the three existing community groups on the park’s northern end and fifteen members...
