Drivers and Impacts of a Recent Annual Grass Invasion: Ventenata dubia and Fire in the Inland Northwest

Creator:: Tortorelli, Claire M.
Abstract:: Biological invasions threaten native biodiversity, alter ecosystem function, and are a major cause of economic losses across the planet. The most impactful invaders alter disturbance regimes and initiate state shifts to outside the historical range of variability of the ecosystem. Concern for ecological and economic losses has prompted a rapid...

Spatial Patterns of Soil Moisture and the Relative Importance of Atmospheric Water Demand Versus Soil Moisture Availability in Limiting Late-summer Growth of Douglas-fir Under a Changing Climate

Creator:: Jarecke, Karla M.
Abstract:: The rapid pace of climate change is increasing tree mortality and highlighting the need to improve the mechanistic understanding of plant function under increased water stress. However, the processes that control soil moisture availability in steep mountainous terrain are poorly understood, as are the relative effects of atmospheric and soil...

Ecosystem Photosynthesis and Forest-Atmosphere Interactions Inferred from Carbonyl Sulfide

Creator:: Rastogi, Bharat
Abstract:: An increase in anthropogenic activities since the industrial revolution, primarily due to burning of fossil fuels and changes in land cover, has resulted in a steady increase in the global mean atmospheric CO2 concentrations. While there is unequivocal scientific evidence on global warming and its multidimensional impacts on natural and...

The Impact of Overlapping Forest Disturbance Across a Stream Network in Western Oregon: Harvesting, Wildfire and Post-Fire Management Effects on Stream Water Nitrate and Riparian Soil Nutrients

Creator:: McCredie, Katherine E.
Abstract:: Understanding the magnitude and longevity of wildfire effects in forested watersheds and subsequent impacts to downstream aquatic ecosystems and communities requires congruent investigation into post-fire aquatic and terrestrial processes. However, results from wildfire studies are often confounded by pre- and post-fire land management actions and based on either hydrologic or...

Potential effects of the invasive grass Ventenata dubia on elk habitat selection within the Starkey Experimental Forest and Range

Creator:: Crum, Keren-happuch R.
Abstract:: The invasive annual grass ventenata (Ventenata dubia) has become an increasing problem within western rangelands. Forage quality of areas infested with ventenata is reduced as its high silica content makes it unpalatable to livestock and wildlife. In the following study, I examined whether significant presence of ventenata affects habitat use...

Drinking Water and PFAS: Learning from Minnesota's 3M PFAS Settlement

Creator:: Bahr, Cody S.
Abstract:: Growing concern regarding the health effects of PFAS exposure through drinking water remains an issue at the forefront of many regulatory hurdles. Current data suggests that PFAS can be the cause of many negative health effects including changes in birth weight, thyroid disease, decreased fertility, and some forms of cancer....

Satellite Monitoring of Earth’s Surface Temperature : Effects of Land Cover, Disturbance, and a Changing Climate

Creator:: Mildrexler, David J.
Abstract:: The Earth’s surface is experiencing unprecedented change. Humanity’s growing population, expanding land-use footprint, and increasing global emissions of atmospheric greenhouse gases affect a vast number of species on Earth and the functioning of virtually all ecosystems. Given the vital interactions and feedbacks between the Earth’s land surface and climate, measurements...

Vegetation Community Data to Inform Climate-Adaptation Management; Gardiner, New York

Creator:: Randazzo, Andrew
Abstract:: Climate change represents an increasing threat to northeastern temperate forests. Nearly all forest communities have been affected by climate change and require climate-adaptation management (Jandl et al. 2018). Climate-adaptation management (CAM) promotes the viability of forested systems and the ecosystem services they provide under current and future climatic conditions (Bolte...

Planning for the Future Forest on the Northern Shawangunk Ridge: Climate-Adaptive Disturbance Preparedness and Response Recommendations

Creator:: Randazzo, Andrew
Abstract:: Mohonk Preserve intends to manage their forestland more actively with the mission of promoting forest health, climate-adaptation, and overall ecosystem health for the benefit of their community and recreational users. Climate-adaptive management recommendations (recommendations that address climate change vulnerabilities —by promoting either resistance, resilience, or transition— while helping to meet...

Fish out of Water: Virgin Spinedace (Lepidomeda mollispinis) in the Santa Clara River, Utah

Creator:: Siefken, Sarah N.
Abstract:: River ecosystems throughout the arid southwestern U.S. are imperiled. Water management infrastructure, climate change, unsustainable water use, and political conflict harm the region's aquatic and riparian ecosystems. This case study surveys one such desert river, an endemic fish species, and conservation efforts in southwestern Utah. The analysis focuses on the...
