Backcountry Trails Near Stream Corridors: An Ecological Approach To Design
Traditional trails near backcountry stream corridors are often designed with disregard to their potential ecological impact. Ecological and trail related literature show that riparian landscapes are sensitive to recreation impacts. This thesis examines concepts for designing trails in ecologically …

Determining the Effects of Water Quality on Stream Metabolic Function of Urban Stream Corridors in Columbus, Georgia
<p>Urbanization alters streams, disrupting their natural habitat and inducing changes in nutrient dynamics and primary productivity. These human-induced interventions diminish ecological structure, homogenizing once-diverse ecosystems and posing a risk of impairment or destruction. Continuous …

Comparative Phylogenetic Analysis in Populations of the Western Cottonmouth (Agkistrodon Piscivorus Leucostoma) Distributed in Three North American Drainage Basins
… that post glacial dispersal patterns using stream corridors have resulted in the present biogeographic assemblage of populations in different drainage basins. Here I use the molecular marker mitochondrial cytochrome b in a molecular phylogenetic analysis to test hypotheses: 1) that post- …

Scale dependent genetic structure of Idaho Giant salamanders (Dicamptodon aterrimus) in stream networks
Stream network structure constrains population processes of freshwater organisms, with individual, population and community level consequences. This consistent structure provides a framework in which examination of life-history influences on population genetic structure may provide general insight. …

A greenways approach to resource management: the process of environmental corridor design
The many miles of our river and stream corridors are some of our country’s most valuable resources. The lands adjacent to rivers possess important agricultural soils, wetlands, fish and wildlife habitats, floodplains, historic communities and places for recreation. In the United States, early uses …

In the Zone: the Effects of Soil Pipes and Dunes on Hyporheic and Riparian Zone Hydraulics and Biogeochemistry
Streams and rivers are a vital part of our ecosystem. They are imperiled by human ecological activities such as urbanization, industrialization, and agriculture which discharge excess nitrate and other pollutants into our waterways. Here, this dissertation seeks to understand the physical and …

Headwater stream network connectivity: biogeochemical consequences and carbon fate
… simple nor static environments. Heterogeneous stream corridors constitute the majority of river network length and regulate cycling of carbon and oxygen as they expand and contract their connections across the landscape. Though headwater streams integrate many biogeochemical signals from the …

Using Emerging Methods to Investigate Stream and Groundwater Interaction at Multiple Spatial Scales
<p>Fundamentally, streams represent physical conduits of water across gradients, yet a more holistic definition reveals stream corridors support a mosaic of living communities in a blend of surface and ground waters. The physical and biogeochemical patterns these dynamic systems support affect …
