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 ([...]

This is a student paper for the 2015 Tropical Ecology UGA Costa Rica Study Abroad Maymester.

This study aimed to analyze the fluctuations in diversity of phytoplankton during tidal cycle. The purpose of this experiment was to observe changes in phytoplankton di[...]

Loggerhead sea turtles (Caretta caretta) are a species of endangered sea turtle, whose nesting and hatching success can be hindered by light pollution. We hypothesize tha[...]

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[...]

This work reviews Georgia coastal policy with respect to the bridging of back-barrier islands (BBIs), or marsh hammocks. It characterized plant and soil composition on B[...]

The Coastal Marshland Protection Act (CMPA) and the Coastal Nonpoint Source (NPS) Program are two of Georgias primary instruments for controlling human influence on the c[...]

Understanding the effects of biodiversity declines on communities and ecosystems is one of the current grand challenges in ecology. Much research has been devoted to quan[...]

Invasive species have negative ecological, economic, and health impacts globally, especially on island ecosystems, but their impacts on ecosystem processes, like scavengi[...]

Water shortages and nutrient pollution in a growing number of basins put human water security and aquatic biodiversity at risk. These challenges are harder to tackle in t[...]

Brunswick, Georgia is the location of an Environmental Protection Agency Superfund site. Polychlorinated biphenyls (PCBs) and heavy metals associated with this site occur[...]

Development and habitat loss pose the most serious threats to reptile persistence. The overall objective of this study was to provide initial assessments of snake behavio[...]

Unsustainable levels of road avoidance or mortality result in the barrier effect, and therefore habitat fragmentation, disrupting metapopulation dynamics and potentially [...]

Pollinators are important to the human food supply and maintenance of healthy ecosystems. This dissertation explores the life history of two pollinating bee groups in the[...]

Temperate savannas contain herbaceous N2-fixing legumes presumed to replenish nitrogen (N) losses from fire. The ability of legumes to fill this role may depend on the fa[...]
