The Wells G and H Superfund site, located in the Aberjona watershed in Woburn, Massachusetts, has been studied by a number of MIT research groups since 1987. Initial research conducted to characterize the hydraulic properties of the wetland deposits, did not indicate the classical trend linking changes in hydraulic conductivity to changes in total porosity. It was hypothesized, therefore, that ...

Geographic patterns in leaf stoichiometry reflect plant adaptations to environments. Leaf stoichiometry variations along environmental gradients have been extensively studied among terrestrial plants, but little has been known about intraspecific leaf stoichiometry, especially for wetland plants. Here we analyzed the dataset of leaf N and P of a cosmopolitan wetland species, Phragmites australi...

The spatial distributions of bacterial communities may be driven by multiple environmental factors. Thus, understanding the relationships between bacterial distribution and environmental factors is critical for understanding wetland stability and the functioning of freshwater lakes. However, little research on the bacterial communities in deep sediment layers exists. In this study, thirty clone...

Abstract Wetlands play a key role in preserving biodiversity and preventing climate change. Their conservation poses an important pressing challenge. In the Mediterranean region, one of threats to wetland survival is lack water due competition for resources. The selection most sustainable resources complex elicitation problem. A novel Water Resources Sustainability Model (WRSM) focused on quali...

We use bird distributions in non-forested coastal wetlands of the Great Lakes to illustrate a new, conceptually explicit method for developing biotic indicators. The procedure applies a probabilistic framework to derive an index that best “fits” an observed assemblage of species, based on preliminary information about species’ responses to human environmental disturbance. Among 215 coastal wetl...

Wetlands are ecologically valuable and complex systems that both link and buffer aquatic and terrestrial systems. Spatial aspects and metacommunity concepts help explain community structure and dynamics, but metacommunity dynamics have not been applied to multiple interacting classes of organisms in temperate wetlands. The aim of this study was to 1) quantify significant patterns of wetland com...

Abstract Invasive plant species can alter natural communities and degrade ecosystem function, yet the factors influencing invasion are poorly understood. The purpose of this study was to characterize environmental drivers community structure invasive prevalence within invaded portions wetland mitigation sites. We sampled vegetation variables (prevalence index, light availability, soil physioche...

Depressional forested wetlands or geographically isolated wetlands such as cypress swamps and Carolina bays are common land features in the Atlantic Coastal Plain of the southeastern US. Those wetlands play important roles in providing wildlife habitats, water quality improvement, and carbon sequestration. Great stresses have been imposed on those important ecosystems due to rapid human populat...

In the eastern U.S. Coastal Plain and Piedmont region, diverse inland wetlands (riverine, depressional, wet flats) have been impacted by or converted to agriculture. Farm Bill conservation practices that restore or enhance wetlands can return their ecological functions and services to the agricultural landscape. We review the extent of regional knowledge regarding the effectiveness of these con...
