The extensive loss of natural wetlands and temporary ponds worldwide has led to their creation and restoration for biodiversity and functional objectives. The assessment of various restoration approaches of these habitats can promote the persistence of their inhabitants, includi…

Coastal wetlands across the Southeastern U.S. coastline are among the most productive ecosystems worldwide, but are expected to experience challenges due to human alterations of the landscape, sea-level rise, and changing frequency of extreme events. Wetlands provide critical ec…
Northern peatlands have accumulated approximately one third of all soil carbon (C) and therefore play an important role in the global C cycle. Besides the C sink function, peatlands are one of the largest biological sources of atmospheric methane (CH4) and represent approximatel…
Because many natural wetlands function as ground water filters in the landscape, wetlands are now protected. Wetlands must have hydric soils, hydrophytic vegetation, and high water tables. We characterized the hydrology and morphology of a soil toposequence that developed on dun…
Wetlands containing aquatic plants have been found to economically provide a mechanism for improving the microbial and other quality of wastewater. The purpose of this study was to elucidate the effect of vegetation and sedimentation on the survival of enteric microorganisms in …
This dissertation uses state-of-the-art palynological analysis, quantitative paleoenvironmental analysis (modem analog technique, detrended correspondence analysis, and cluster analysis) and geochronology ( 14 C, 210 Pb, and biostratigraphy) on wetland sediments from the ridge, …
Wetlands contribute an estimated 25% of the global annual methane (CH4) emissions. However, delineation of the processes responsible for the large variations in emission rates found within and across wetland types has been challenging. Field measurements were collected in Franci…
Issues related to the use and management of wetlands have received considerable attention in recent years in the wake of fast disappearance of this natural resource. Inadequate institutional arrangements or property rights have been cited as an important causal factor for this d…
Large wetlands are rare in Afghanistan. Afghanistan's few large wetlands are imperative for the sustainability of the local human and wildlife populations, and globally renowned for being indispensable staging and breeding areas for migratory waterfowl, waders and flamingos. A s…
Global climate is predicted to have significant impacts on the chemical, biological, and physical characteristics of wetlands and the watersheds in which they are contained. In particular, climate prediction models suggest a significant increase in extreme precipitation events -…
The floodplain wetlands of the Hadejia-Jama'are Basin, Northern Nigeria are a valuable economic and environmental resource and similar hydrologically to the Inner Niger Delta and the Senegal Valley. Seasonal inundation is the key. Drought and large-scale water resource schemes u…
This study aims to develop models predicting the depth, extent and volume of flooding in the Hadejia-Nguru wetlands of Nigeria from satellite sensor images. In subregions representative of the entire wetlands over 1,500 rigorously coordinated and geocoded depths were observed, s…
Organic matter stored in wetlands constitutes a globally significant terrestrial carbon pool interacting with atmospheric carbon via unique ecological processes that release CH4 but take in CO2. Efforts are ongoing to quantify the role of wetlands in terrestrial-atmosphere carbo…
This thesis aims to study ecological design through the exploration of migratory bird habitat expansion in cities in the context of climate change. The thesis begins with a literature review of basic understanding of the Pacific Flyway and widely accepted theories and landscape …
Larval anurans may constitute the primary biomass of animals in geographically isolated wetlands (GIWs), but few studies have attempted to identify factors that influence larval body stoichiometry or their role in nutrient storage within GIWs. I measured body stoichiometry acros…
