Abstract To stop the worldwide decline of wetlands, conservation measures like restoration, protection and construction these ecosystems are indispensable. However, wetland could influence mosquito populations. We analysed how affect species composition abundance mosquitoes by conducting a systematic literature review generated results from 113 selected articles. Thereby, we separately assessed...
We compared potential denitrification and phosphorus (P) sorption in restored depressional wetlands, restored riparian buffers, and natural riparian buffers of central Ohio to determine to what extent systems restored under the U.S. Department of Agriculture’s Wetland Reserve Program (WRP) and Conservation Reserve Program (CRP) provide water quality improvement benefits, and to determine which ...
As the impacts of anthropogenic nitrogen (N) pollution of the biosphere become increasingly evident, the fate of excess N in landscapes is recognized as one of the most pressing environmental research needs. Most of this N disappears somewhere in route from the sites of application (mainly on land) to coastal and offshore marine waters; however the precise regions and mechanisms of removal rema...
Reflecting a global trend, freshwater wetlands in Madagascar have received little conservation or research attention. Madagascar is a global conservation priority due to its high level of species endemism but most work has focused on protecting forests. For the first time, we investigated the state of wetlands across the country to determine the effects of human disturbance. We conducted a rapi...
Hydrological restoration of historically isolated wetlands may mitigate phosphorus (P) loss. The objectives of this study were to quantify P in soil, determine effect of (1) soil characteristics on P release, and (2) antecedent soil hydrological conditions on P dynamics. Humic/fulvic acid bound P and residual P accounted for majority of P (>78%) in surface soils. Soils with highest nutrient sta...
Abstract Wetlands have a significant impact on healing degraded ecosystems and restoring environmental balance for their broad range of benefits. Lakes are considered type wetlands combining terrestrial aquatic ecosystems, it is important to restore lakes regain the ecological services provided by these systems, which might been severely altered from human pressure, pollution urban development....
Ammonia-oxidizing organisms play an important role in wetland water purification and nitrogen cycling. We determined soil nitrification rates and investigated the seasonal and spatial distributions of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in three freshwater wetlands by using specific primers targeting the amoA genes of AOA and AOB and real-time quantitative polym...
A major component of river restoration is the recreation of instream physical habitat heterogeneity and re-establishment of the linkage between the in-channel and adjacent floodplain environment. Re-engineering channels to reinstate a more natural form and the restoration of water and sediment transfer can bring multiple benefits particularly if undertaken as part of an environmental strategy f...
Measurement of soil carbon (C) is important for determining the effects of Everglades restoration projects on C cycling and transformations. Accurate measurement of soil organic C by automated carbon–nitrogen–sulfur (CNS) analysis may be confounded by the presence of calcium carbonate (CaCO3) in Everglades wetlands. The objectives of this study were to compare a loss-onignition (LOI) method wit...
