Biogeochemical Effects of Silvicultural Management on Intermittent Streamside Management Zones in the Coastal Plain of Alabama

Colson, Christopher (2008-05-15)

Three experimental intermittent watersheds in the Coastal Plain of Alabama were subjected to varying Streamside Management Zone (SMZ) silvicultural treatments in 2000: reference, partial cut, and clearcut. Biomass and ...

Biogeochemical Influence of Chinese Privet in Riparian Forests in West Georgia and the Influence of Oyster Harvesting in Apalachicola Bay, Florida

Mitchell, Jennifer (2009-05-04)

In the Southeastern U.S., urbanization influences nutrient availability, species composition, and water quality among other ecosystem processes. This study examined the influence of invasive species spread, facilitated ...

Effect of Forest Structure on the Understory Light Environment and Growth Potential of Oak Seedlings in a Closed Canopy Riparian Forest

Ostrom, Bradford (2005-12-15)

This research was designed to examine the relationship between the residual structure following low intensity partial cutting regimes and the light characteristics found in a riparian hardwood forest. The relationships ...

Effects of Sediment Deposition on Aboveground Net Primary Productivity, Vegetation Composition, Structure, and Fine Root Dynamics in Riparian Forests

Cavalcanti, Guadalupe (2004-05-15)

This study examined how increased sediment deposition from anthropogenic disturbance impacts functions performed by riparian forests associated with ephemeral streams. Specifically, this study looked into aboveground net ...

Effects of sedimentation on productivity, nutrient cycling, and community composition in riparian forests associated with ephemeral streams at Ft. Benning, GA, USA

Jolley, Rachel (2008-05-15)

The societal value of riparian forests in improving water quality by trapping sediments and pollutants is well understood. However, it is not clear how sedimentation impacts the overall integrity of riparian systems. In ...

Exploring natural and artificial regeneration techniques for developing high-quality bottomland oak stands

Taylor, Troy (2005-12-15)

Bottomland hardwood forests of the southeastern United States are among the most diverse and productive in the country. In the past, many of these areas were not managed soundly for timber production and, as a result, are ...

Hydrology, Water Quality, and Channel Morphology Across an Urban-rural Land Use Gradient in the Georgia Piedmont, USA

Schoonover, Jon (2005-12-15)

The southeastern United States is experiencing rapid urban development. Consequently, Georgia’s streams have been threatened by hydrologic alteration, nutrient and bacteriological impairment, and channel morphometry changes ...

Impacts of Land Use/Cover on Ecosystem Carbon Storage in Apalachicola, FL

Nagy, Rachel Chelsea (2009-03-10)

Rapid coastal development in response to a growing population raises concerns about human degradation of ecosystems. The importance of the carbon cycle and its role in climate regulation warrant the study of the effects ...

Impacts of urbanization on carbon balance and human health risk: I. & II. Soil carbon dynamics under impervious surfaces and III. Water quality influences on a common West Nile virus vector.

Majidzadeh, Hamed (2017-01-05)

A significant increase in urbanization will be observed during the next fifty years. Global environmental changes cannot be addressed without a better understanding of biogeochemical cycles in urban areas. Thus, more insight ...

Influence of Chinese Privet (Ligustrum sinense Lour.) on Riparian Forests of the Southern Piedmont: Net Primary

Brantley, Evaden (2008-12-15)

The spread of invasive, nonnative vegetation in the Southeast has been identified as a critical concern for the maintenance of ecosystem biodiversity and impacts on the forest industry. One example of such a species is ...

Legacy Sediments in Southeastern United States Coastal Plain Streams

Casarim, Felipe M. (2009-12-14)

Soil erosion and sedimentation are natural processes that occur throughout the landscape. However, athropogenic disturbances may result in an increase in either of these processes, or both. Many studies reported the extensive ...

A Meta-Analysis of Bird-Window Collision Solutions

Colbaugh, Jessica (2023-11-27) ETD File Embargoed

North American bird populations are declining and bird-window collisions are a leading cause, resulting in 365 - 988 million bird deaths each year in the U.S. alone. One approach aimed at reducing these collisions is ...

Modeling impact of Land Use/ Cover changes on Water Quality and Quantity of Fish River Watershed

Singh, Harsh Vardhan (2010-07-13)

Hydrologic and water quality models are widely used for assessing the impacts of land use/cover (LULC) changes on water quality and quantity. However, their credibility for predicting LULC change impacts has not been tested ...

Modeling Methane and Nitrous Oxide Exchanges between the Atmosphere and Terrestrial Ecosystems over North America in the Context of Multifactor Global Change

Xu, Xiaofeng (2010-11-19)

Methane (CH4) and nitrous oxide (N2O) are two potent greenhouse gases which in sum contribute to more than one fourth of global warming caused by anthropogenic activities. In the meantime, CH4 and N2O play significant roles ...

Morphological and Nutritional Development of Three Species of Nursery-Grown Hardwood Seedlings in Tennessee

Santos, Humberto (2006-12-15)

We followed the morphological and nutritional development of three common hardwood species growing under typical cultural practices in a southern hardwood nursery. Yellow poplar was by far the largest seedling at the end ...

Predicting Light Transmittance and Seedling Growth Across a Gradient of Riparian Forest Canopy Structures

Lhotka, John (2006-05-15)

In response to shifts in forest management that have favored continued retention of forest cover, the objective of this study was to explore how forest structure influences the understory light environment and seedling ...

Response of Aquatic Biota to Changing Land Use Pattern in Streams of West Georgia, USA

Helms, Brian (2008-05-15)

Watershed land use change is one of the most pervasive influences facing streams in the southeastern United States. In particular, watershed urbanization has a potentially dramatic impact on stream biota. Through direct ...
