|Increased Rates of Soil Respiration and Microbial Enzyme Activity Under Two Complementary Experimental Warming Methods: Implications for Carbon-Climate Feedbacks
||Soils contain large amounts of carbon which is susceptible to increased decomposition with increasing global surface temperatures under climate change. It is uncertain how soil carbon will react to long-term climate change because of the differences...
|Cliff Ecology of the Big South Fork National River and Recreation Area
||Most of the world’s cliff ecosystems remain unexplored by biologists, yet the biodiversity on cliffs may be threatened by recreational activities like rock climbing. This study characterized the vascular plants, bryophytes, and lichens along 50 verti...
|An urban forest in a rural town: biodiversity, ecosystem services, and management of trees on the Appalachian State University campus
||The objectives of this study were to: 1) identify all trees on campus, 2) determine the size distributions for each tree species, 3) assess the health and risk status of each tree, and finally, 4) to quantify and compare ecosystem services of trees o...
|Genetically–Mediated Leaf Chemistry in Invasive and Native Black Locust (Robinia pseudoacacia L.) Ecosystems
||Black locust (Robinia pseudoacacia L.) is one of the few examples of an intra-continentally invasive species. Few genetic studies have been conducted on black locust and none compare North American invasive and native populations. Chapter 1 is a sum...
|Soil Microbial Community Responses Following Severe Wildfires in the Linville Gorge, Burke County, NC.
||The belowground community response to wildfire is often linked to the chemical, physical, and biological properties of soils. Fundamental processes such as soil respiration are strongly influenced by changes in soil biogeochemical parameters caused b...
|Avian Guano as a Nutrient Input to Cliff-Face Ecosystems in Western North Carolina
||Terrestrial cliff-face ecosystems are unique habitats that harbor diverse vegetational communities and an array of animal species. However, fundamental processes such as nutrient cycling in cliff-face ecosystems remain poorly understood. Cliff-face v...
|Impacts, Genetic Diversity, And Land Management Strategies Of Post-Fire Paulownia Tomentosa Invasions In The Linville Gorge Wilderness Area, Burke County, NC
||Paulownia tomentosa (princess tree) is an exotic-invasive tree species in North America with widespread naturalized populations. Few studies have quantified its impact on native plant communities, characterized its genetic diversity within and acros...
