Wetlands are valuable ecosystems because they harbor a huge biodiversity and provide key services to societies. When natural or human factors degrade wetlands, ecological restoration is often carried out to recover biodiversity and ecosystem services (ES). Although such restorations are routinely performed, we lack systematic, evidence-based assessments of their effectiveness on the recovery of...

every year a large number of migratory wintering water birds, rest in the wetlands situated in the northern provinces of iran. the wetlands are very important ecosystems for these creatures. due to ecological importance of water birds, the results of this study (the birds’ populations and their changes) are helpful to monitor them and are especially important to manage the wetlands. in this stu...

according to the report published by the united nations scientific committee on the effects of atomic radiation (unscear) in 2000, ramsar city in northern iran, has some inhabited areas with the highest known natural background radiation levels in the world (1). the annual radiation absorbed dose in high background radiation areas (hbras) of ramsar is extraordinary high, reaching 260 msv that i...

Water reclamation and reuse is being actively promoted in Australia. In Queensland, surface-flow constructed wetlands with a diversity of macrophyte types offer the greatest potential for effluent polishing. Constructed wetlands in subtropical climates in coastal regions and arid climates in inland western regions are conducive to high macrophyte growth rates and nutrient removal, in particular...

Plant taxa identified in 90 U.S. Great Lakes coastal emergent wetlands were evaluated as indicators of physical environment. Canonical correspondence analysis using the 40 most common taxa showed that water depth and tussock height explained the greatest amount of species-environment interaction among ten environmental factors measured as continuous variables (water depth, tussock height, latit...

Constructed wetland technology has been widely applied around the world to treat domestic wastewaters from the single family home to small communities. Constructed wetlands can be classified as either surface flow wetlands (similar to natural wetlands) or subsurface flow wetlands, where the wastewater flows through a media. Subsurface flow constructed wetlands can either be horizontal flow syst...

In Burkina Faso, wetlands play an important role in the country’s economy. Dem Lake, one of Ramsar sites international importance inscribed 2009, and is today facing severe degradation under combined effect climate change, poverty, population growth, pressure from anthropogenic activities. Also, goods services Lake ecosystems have not yet been studied to provide us with information on their cos...

functioning in a restored wetland when compared with its natural counterpart. We used the denitrification enWetland restoration projects are frequently evaluated by their hyzyme activity (DEA) assay, a measure of the potential of drologic roles and vegetation characteristics, but their success in rea microbial population to produce the nitrate reductase storing biogeochemical processes, such as...

Lead is a toxic heavy metal that when ingested can cause death or sub-lethal fitness effects. Despite its toxicity, it still widely used in recreational and management shooting globally. To reduce the impacts of lead on wildfowl, recent European Union legislation has banned use shot around wetlands from 2023. Understanding effectiveness such mitigation vital to inform future policy. On Islay, S...
