Miqan desert wetland is one of the 10 major wetlands in Iran. In 2008, it has changed into a non-hunting area due to its fragile ecology.  Evaluating the change trends of the wetland and the use of its surrounding lands is of high significant in order to maintain the wetlands. In this regard, the satellite images of the ETM+ and OLI sensors of years 2002 and 2013 were initially collected. ...

Los microplásticos son fragmentos plásticos de un tamaño menor a 5 mm diámetro que actualmente considerados contaminantes emergentes. Ante la falta información relacionada con MPs en zona, presente investigación tuvo finalidad evaluar abundancia y características las playas Las Comadres, El Estero Uverito, distrito Tablas, provincia Santos. muestras fueron colectadas los meses agosto octubre 20...

Many wetlands of the Great Lakes region are increasingly dominated by species of cattails, including the native Typha latifolia, the introduced Typha angustifolia, and their hybrid Typha glauca. Cattails are observed to form dense stands of live and dead biomass that may reduce plant diversity and compromise wetland habitat value. Cattail expansion has been used as an indicator of environmental...

Denitrification in constructed wetlands can be very important in the treatment of swine lagoon effluent when land application areas are limited. The objectives of this investigation were to determine (i) the denitrification enzymeactivity (DEA) in themarsh sediments ofmarshpond-marsh (MPM) constructed wetlands, (ii) changes in DEA with additions of carbon and nitrate, and (iii) the response of ...

Ranaviruses have been associated with most of the reported larval anuran die-offs in the United States. It is hypothesized that anthropogenically induced stress may increase pathogen prevalence in amphibian populations by compromising immunity. Cattle use of wetlands may stress resident tadpole populations by reducing water quality. We isolated a Ranavirus from green frog Rana clamitans (n = 80...

Wetlands are sensitive ecosystems that are increasingly subjected to threats from anthropogenic factors. In the last decades, coastal Mediterranean wetlands have been suffering considerable pressures from land use change, intensification of urban growth, increasing tourism infrastructure and intensification of agricultural practices. Remote sensing (RS) and Geographic Information Systems (GIS) ...

Water draining abandoned mines or mine sites is often acidic and contains relatively high concentrations of dissolved metals and sulfate. Such water (AMD) arises from the oxidative dissolution of sulfidic minerals, such as iron pyrite (FeS2), exposed by mining activities. As AMD production can occur over a very long time scale, passive remediation systems are becoming increasingly important in ...

Geographically isolated wetlands (GIWs) are wetlands completely surrounded by uplands. While common throughout the United States (U.S.), there have heretofore been no nationally available, spatially explicit estimates of GIW extent, complicating efforts to understand the myriad biogeochemical, hydrological, and habitat functions of GIWs and hampering conservation and management efforts at local...

Wetlands are complex ecosystems often occupying the interface between land and water. Wetlands function as part of the landscape with or without the presence of humans. They have value because many of their functions have proved to be useful to humans but are at the same time ecologically sensitive and adaptive systems. The increasing demand and pressures on wetlands without understanding their...
