Trophic cascades and large mammals in the Yellowstone ecosystem

Creator:: Painter, Luke E.
Abstract:: Reintroduction of wolves to Yellowstone National Park (YNP) in 1995-96 provided a rare opportunity to observe the response of an ecosystem to the return of a top predator, including possible reversal of decades of decline of aspen, cottonwood, and tall willows suppressed by intensive herbivory on elk winter ranges. To...

Soil Fire Ecology: Assessing Wildfire Severity Impacts on Pacific Northwest Forest Soil Carbon

Creator:: Fleetwood, Shea
Abstract:: Pacific Northwest temperate rainforests are anticipated to experience increasingly frequent and severe wildfires in the foreseeable future due to climate change, increased fuel loads, and deforestation. Soil, underlying these forests, is the largest terrestrial carbon (“C”) reservoir. Fire disturbance influences soil C persistence, the timeframe and magnitude of which remain...

Litter controls of microbial community composition and function in forest soils

Creator:: Brant, Justin B.
Abstract:: Most carbon (C) transformations in soil are carried out by a diverse and complex soil microbial community. The size and composition of the soil microbial community is determined by poorly understood interactions between the quantity and chemical composition of plant inputs, as well as climate. Given the metabolic diversity of...

Provenance, lifespan, and phylogeny : testing a conceptual framework for plant community management

Creator:: Benfield, Cara D.
Abstract:: Successful conservation management requires an understanding of how species respond to intervention. Native and exotic species may respond differently to management interventions due to differences arising directly from their native or exotic origin (i.e., provenance) or from differences in life-history or phylogenetic lineage that are associated with provenance. Thus, selection...

Functional profiles of soil microbial communities in second-growth Douglas-fir forests of the Pacific Northwest

Creator:: McGinnis, Megan L.
Abstract:: Forests are one of the largest repositories of terrestrial C. Understanding factors that drive organic matter transformations and nutrient efflux from these systems is therefore highly important. Temperate forests are of particular significance due to the large fraction of C that is stored below ground in the soil. Characterizing nutrient...

Response of soil microbial communities and nitrogen cycling processes to changes in vegetation inputs

Creator:: Brewer, Elizabeth Ann
Abstract:: Changes in the type and amount of plant inputs can occur gradually, as with succession, or rapidly, as with harvesting or wildfire. With global change it is anticipated that both gradual and immediate scenarios will occur at increasing frequency. Changes in vegetation inputs alter the quality and quantity of soil...

Detrital Input and Removal Treatment (DIRT) Network Soil Analysis in the UMBS Michigan Field Site

Creator:: Bushyhead, Coryn N.
Abstract:: Soil contains approximately 75% of the carbon pool on land - three times more than the amount stored in living plants and animals (Schlesinger 1999). Therefore, soils play a major role in maintaining a balanced global carbon cycle. Models of the soil carbon ecosystem assume a strong relationship between organic...

A Study of Urban Vegetable Garden and their Soils in Corvallis and Portland, OR

Creator:: Nelson, Michael, II
Abstract:: Urban agriculture (UA) is defined as the production of food crops or livestock within urban areas. Despite its popularity in the United States, research into UA systems suffers from a general underrepresentation of commercial urban systems. As a result, urban growers often have unique technological needs that are unmet by...

Response of Soil Temperature, Moisture, and Respiration Two Years Following Intensive Organic Matter and Compaction Manipulations in Oregon Cascade Forests

Creator:: Gallo, Adrian Carlos
Abstract:: Forest soils contain a substantial portion of global terrestrial carbon stores. Forest management can influence the soil carbon pool and how soil organic matter functions. The long-term productivity of forests is an ongoing goal where land managers utilize biomass and timber. A site-specific understanding of intensively managed forests can ensure...

Lower and Middle Devonian carbonate-platform and outer-shelf-basin deposits flanking Railroad Valley, Nevada

Creator:: Nelson, Storr L.
Abstract:: Lower and Middle Devonian strata crop out on the former stable carbonate platform that existed in the Quinn Canyon Range, through the carbonate shelf edge in the Pancake Range, to the carbonate slope and outer-shelf basin in the Reveille Range. The strata of the Reveille Range record a transition from...
