Macroinvertebrate Biomonitoring Criteria and Community Composition in Seasonal Floodplain Wetlands of the Upper Missouri River
… effects of disturbances in seasonal floodplain wetlands. I also examined differences in macroinvertebrate community structure in forested and emergent seasonal floodplain wetlands. As part of a U. S. EPA REMAP study, aquatic macroinvertebrates were sampled to develop biomonitoring criteria for …

Taxonomic homogenization of plant communities in Illinois wetlands and the role of wetland compensation
… represents a severe threat to biodiversity. Wetlands are especially susceptible to biotic homogenization; however, this process has rarely been documented and represents just one of many possible outcomes of compositional change. Additionally, it has been suggested that the practice of …

Hydraulic Resistance due to Emergent Wetland Vegetation
… hydraulic resistance due to vegetation in emergent wetlands are crucial to wetland design and management. Hydraulic models that consider vegetation rely on an accurate determination of a resistance parameter such as a friction factor or a bulk drag coefficient. At low Reynolds numbers …

Assessing Coastal Plain Wetland Composition using Advanced Spaceborne Thermal Emission and Reflection Radiometer Imagery
… and Reflection Radiometer (ASTER) to separate wetlands from uplands in a study of 870 locations on the Virginia Coastal Plain. We used the first five bands from each of two ASTER scenes (6 March 2005 and 16 October 2005), covering the visible to the short-wave infrared region (0.52-2.185υm). We …

Sub-Pixel Classification of Historical and Current Marsh Habitat For the Eastern Mississippi Gulf Coast Using Remotely Sensed Images
<p><p>Coastal Wetlands are changing at unprecedented rates (Reyes et al., 2000 & 2004) and the ability to monitor their changes remotely over time has become increasingly important (Hilbert, 2006 & Blaschke, 1996). The focus of this project was to complete a historical sub-pixel prediction land use …

A Market-Based Approach for Valuing Ecosystem Services on Coastal Properties
… efforts to assess ecosystem services provided by wetlands, this research focuses on estimating the private monetary value of wetland services to residential property owners in Louisiana and Alabama using a hedonic price model. Understanding that tradeoffs must be made with limited resources, …

Characterization of urban wetland vegetation and management practices
<p>Urban wetlands are important ecosystems that moderate flooding risks and improve water quality. Vegetation is a key component of urban wetlands; plants promote sedimentation, play critical roles in biogeochemical cycling, and provide food and habitats for other organisms. My research focuses on …

A Vegetation-Based Index of Biotic Integrity for Wetlands of Kentucky
… efforts to assess the status of remaining wetlands and regulate their development. The Clean Water Act and the policy of “No Net Loss” have resulted in a system of permitting and mitigation for impacts to wetlands. Professional judgments of wetland quality are inherent in regulatory …

Behavior, Nest Site Selection and Success of Black Terns (Chlidonias niger)
<p>The Black Tern (<em>Chlidonias niger</em>) population has markedly declined over several decades in northern North America, the causes of which are still largely unknown. I monitored nest success and wetland use by Black Terns in three colony sites in northern Michigan throughout 2017 and 2018 …
