Urban wetlands can provide valuable ecological services through filtration and moderation of non-point source pollutants. They provide habitat for wildlife, green space, and recreational opportunities for nearby human populations. We investigated an isolated section of an urban wetland in the Cleveland metropolitan area to determine the overall quality of the vegetation and to evaluate the site...

Urban ecological restoration can produce important social benefits in addition to those biophysical improvements traditionally included in the evaluation of restoration success. Achieving social benefits requires local people to participate in planning, implementation, and evaluation of restoration. Restoration also provides experimental opportunities to study the interactions between human and...

One of the ways to reduce the amount of wastewater pollution is the use of constructed wetlands. In this research, the performance of a hybrid constructed wetland with pumice ore and vetiver plant on urban wastewater has been investigated. Hybrid wetlands with these specifications were constructed in the vicinity of wastewater treatment at the Isfahan University of Technology. To evaluate the p...

Interand intra-site comparisons of the nitrogen (N) stable isotope composition of wetland plant species have been used to identify sources of N in coastal areas. In this study, we compared δ15N values from diff erent herbaceous wetland plants across 34 diff erent coastal wetlands from the fi ve main Hawaiian Islands and investigated relationships of δ15N with land use, human population density,...

Self-transmissible and mobilizable plasmids contribute to the emergence and spread of multidrug-resistant bacteria by enabling the horizontal transfer of acquired antibiotic resistance. The objective of this study was to capture and characterize self-transmissible and mobilizable resistance plasmids from a coastal wetland impacted by urban stormwater runoff and human wastewater during the rainy...
