Understanding the mechanisms behind the maintenance of hybrid zones and the means by which parasitism can either favor or penalize introgression is likely to be crucial f[...]

Understanding individual variation in behavior is a core focus of behavioral ecology and holds important implications for wildlife management. While most studies have exa[...]

Developmental plasticity, the irreversible modification of phenotypes in response to the developmental environment, carries critical implications for ecology, evolution, [...]

Mosquito-vectored pathogens are globally significant sources of disease across equatorial areas and have expanded into temperate regions of the world. This dissertation e[...]

Deforestation has the potential to alter regional atmospheric dynamics, namely the motion of vapor, energy partitioning, and convective storm formation. Rates of photosyn[...]

Within the Mid-Atlantic Bight, there are interesting latitudinal patterns of physiological change. Physiological variation in oxygen consumption for Geukensia demissa has[...]

Parasite infections in host populations frequently display seasonal patterns that can shape host behavior, fitness, and population dynamics. Despite recognition that seas[...]

Integrated crop-livestock systems can restore ecosystem services like biological control and nutrient cycling to agroecosystems. However, the joint production of livestoc[...]

Humans rely on freshwater ecosystems for a range of values including biodiversity, cultural, supporting, provisioning, and regulating services. Freshwater ecosystems have[...]

Ecosystem engineers have a central role in modifying key attributes of the environment that affect species throughout their community. The outcome of their environmental [...]

Our current understanding of responses of predators to nutrient enrichment of nitrogen (N) and phosphorus (P) is limited. Here, I investigated responses of larval salaman[...]

Emerging diseases are rapidly becoming a global conservation issue, and traditional approaches to understanding transmission among in-situ populations often involved inve[...]

Over the past 30 years, lianas (woody vines) have become more dominant in Neotropical rainforests. The objective of this study was to compare root functional traits of Ne[...]

Recent observations have shown a decline in fish populations in the Conasauga River. Anecdotal evidence also suggests similar trends for macroinvertebrates, potentially i[...]

The Broad River Watershed Association (BRWA) advocates for protection and management of the Broad River Watershed in northeast Georgia. BRWA reached out for help in under[...]

Humans have substantially altered global carbon (C), nitrogen (N), phosphorus (P), and hydrologic cycles. These alterations are negatively impacting ecosystem structure a[...]

Temperate forests of eastern North America have been transformed by centuries of disturbance. Before European Colonization, these oak- (Quercus spp.) and pine-dominated ([...]

Food quality in low-gradient streams of the southeastern coastal plain is controlled by streamflow, connectivity to the floodplain, and the position within the watershed.[...]

I compare Malaise trapping to rearing as methods for collecting Ichneumonidae in Guanacaste, Costa Rica. In total, 6707 Ichneumonidae were collected in the one year of Ma[...]

Habitat conservation plans have been used since 1982 when Section 10 was added to the Endangered Species Act, but were not heavily utilized until the Clinton administrati[...]

The nitrogen cycle is one of the most complex and spatially heterogeneous elemental cycles crucial for life on earth. The southern Appalachian Mountains are currently exp[...]

Exotic species are a major component of current, global-scale ecological change. Even otherwise remote and pristine areas, such as the Cape Horn Biosphere Reserve (CHBR)[...]

Geographical and ecological restrictions are the primary drivers of freshwater fish imperilment within the southeastern United States. To effectively manage existing pop[...]

This dissertation explores the relative importance of two macronutrients, nitrogen (N) and phosphorus (P), for primary production in coastal ecosystems of The Bahamas and[...]

Increasing vigor of existing populations and reintroduction of propagules will be necessary for persistence of the federally endangered shrub, Lindera melissifolia. The o[...]
