Future Human Evolution

Creator:: Horst, Donovon Emile and Quick, Devon
Abstract:: The Earth is warming at a seemingly unstoppable rate, a virus is ravaging the world, and international tensions are ever-present. This brings me to wonder, how will we survive in the future? And as an artist that question turns into: what will we look like in the future? Partnered with...

Forb Community Response to Various Disturbances in the Pacific Northwest Bunchgrass Prairie

Creator:: Watson, Brogan L.
Abstract:: Observed declines in native pollinator species worldwide has generated concern and focused research into the disturbances, past and present, which may have contributed to these losses. In grasslands, for example, habitat degradation and fragmentation from historical and current crop production and livestock grazing has left only a few remnants of...

Grazing Effects on Fuels and Plant Community Characteristics across Three Community Types in Wyoming Big Sagebrush Steppe

Creator:: Thomas, Tyler W.
Abstract:: Livestock grazing is the prominent land use in Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) steppe and has been present since the late 1800’s. There have been calls to remove livestock grazing from rangelands as historic grazing practices resulted in the degradation of some...

Vegetation as Impacted by Soil Characteristics and Moisture in a Conservation Wetland, Willamette Valley, OR

Creator:: Aslan, Fevziye
Abstract:: Wetland degradation has negative influences on wetland functions and services. The understanding of wetland functions requires the intersection of two science disciplines, ecohydrology and plant physiology for a correct approach on wetland restoration and management. Although studies assessing ecohydrological relationships to protect wetlands are relatively common, studies evaluating both ecohydrological...

The Ecological Recovery of Saguaro National Park after Removal of Cattle Grazing and Associated Succession

Creator:: Summers, Ryan J.
Abstract:: In the area that is now Saguaro National Park East, grazing began in the 1880's. Because of the impact to the iconic saguaro cactus as well as all palatable plant species in the area, ecological damage in the park were determined to be so great that anti-grazing conservationists challenged the...

Comparison of Common Ravens in Sage-grouse Core and Non-Core Areas: Assessing Predator Densities Related to Anthropogenic Features

Creator:: Revekant, Claire L.
Abstract:: Greater sage-grouse (Centrocercus urophasianus: hereafter sage-grouse) abundance and distribution in North America has declined over the last century. Many factors have contributed to this decline, including habitat loss and fragmentation from human development with an associated potential for increased predation. While human development has been connected to lower sage-grouse demographic...

Plant Species Diversity and Pasture Productivity of a High-input Dairy Pastureland System and a Low-input Sheep Pastureland System in Western Oregon, USA

Creator:: Anderson, Jordan D.
Abstract:: The sustainable use of natural resources, including the goods and services provided by pasturelands and rangelands, is of growing importance due to climatic uncertainty and population growth. Maintaining high productivity in livestock operations is necessary as land availability diminishes and global populations rise. The potential negative impacts to the environment...

Forage production, dual use potential, and trait variation in chicory grown in the Pacific Northwest

Creator:: Seeno, Elizabeth
Abstract:: Grasslands in the Pacific Northwest are characterized by seasonally wet, acidic soils that mainly support cool season grasses and a limited number of legume species. A major limitation to efficient animal production in grass-dominant pastures is the decline in the herbage growth rate and nutritional quality of forage from late...

Mycorrhizal Fungi on the Sagebrush Steppe: Benefits for Restoring Keystone Rangeland Plant Species

Creator:: Prado-Tarango, David E.
Abstract:: Arbuscular mycorrhizal fungi (AMF) are plant symbionts that associate with the vast majority of terrestrial plants species. The AMF colonizes the plant roots by penetrating the root cortical cells, where the fungi exchanges mineral nutrients with the host plant for photosynthates. This association exists as a complex system in which...

Permineralized Mesozoic Moss Gametophytes and their Implications for Bryophyte Evolution

Creator:: Bippus, Alexander C.
Abstract:: Mosses (Phylum Bryophyta) are widely considered to be among the most ancient groups of land plants (embryophytes) and they are the second most speciose embryophyte phylum with ~13,000 extant species. Despite their diversity and antiquity, mosses have a limited fossil record, which primarily consists of gametophytes entombed in Cenozoic amber....
