The failure of managed wetlands to provide a broad suite of ecosystem services (e.g., carbon storage, wildlife habitat, groundwater recharge, storm-water retention) valuable to society is primarily the result of a lack of consideration of ecosystem processes that maintain productive wetland ecosystems or physical and social forces that restrict a manager's(More)
Wetland management in the United States has never been as challenging as in today's highly modified landscape. Initially, wetland science and management emerged as professions in response to widespread conversion of wetlands to other uses and concerns over negative impacts on wildlife populations, especially migratory birds. Consequently, wetland management(More)
Playas are shallow depressional wetlands and the dominant wetland type in the non-glaciated High Plains of the United States. This region is one of the most intensively cultivated regions in the Western Hemisphere, and playas are profoundly impacted by a variety of agricultural activities. Conservation practices promoted through Farm Bills by the U.S.(More)
Land use mediated habitat changes are associated with global amphibian declines. Intensive farming occurs in the Southern High Plains, USA, causing habitat loss through cultivation and subsequent sedimentation of playa wetlands. We determined the effects of sedimentation and other factors (e.g., hydroperiod, vegetative cover, wetland volume loss due to(More)
Coastal wetlands are essential components of healthy and productive coastal fisheries, and nowhere within the lower 48 states has the critical linkage between wetlands and fisheries resources been more clearly demonstrated than in the Gulf Mexico (e.g., Chesney et al. 2000, Crain et al. 1979). Louisiana alone, for example, generates 30% of the nation's(More)
"Integrating estimates of ecosystem services from conservation programs and practices into models for decision makers" (2011). Abstract. Most government agencies involved in land management are seeking consistent approaches to evaluate the effects of specific management actions on ecological processes and concurrent changes on ecosystem services. This is(More)
Playa wetlands (shallow, circular, depressional wetlands) in the Southern Great Plains are essential to the maintenance of regional biodiversity. However, the relative importance of habitat characteristics for maintaining avian species richness and density in playas is unknown. We examined influences of local- and landscape-scale characteristics on avian(More)
Amphibian metamorphosis is complex and larval morphology and physiology are completely restructured during this time. Amphibians that live in unpredictable environments are often exposed to stressors that can directly and indirectly alter physiological systems during development, with subsequent consequences (carryover effects) later in life. In this study,(More)
Alterations to wetland hydrology associated with conversion of grassland watersheds to croplands can alter functional components that drive many wetland ecosystem services. Biodiversity provisioning is one of many services that can be negatively impacted by grassland conversions. Our objective was to compare amphibian communities of playa wetlands in native(More)
