Understanding ecosystems and their zonation based on their characteristics and sensitivities is an essential step in protecting natural resources and the sustainability of their habitats. The Mediterranean Wetland Habitat Classification System (MEDWET) is used to identify Bakhtegan wetland, Fars Province, Iran, by hierarchical classification of their habitats, in which they are identified and d...
Conservation management of wetland-dependent species generally focuses on preserving or increasing wetland habitat. However, the quality of the landscape matrix (the intervening non-wetland portion of the landscape) has been shown to be more important than wetland availability for some wetland-dependent species. We used meta-analysis to compare the effects of wetland amount (measured as the are...
Alligator weed Alternanthera philoxeroides (Mart.) Griseb (Amaranthaceae) is being reported for the first time from Kashmir, India. Alternanthera philoxeroides was collected in 2008 during the vegetation survey of Wular Lake, a wetland of international importance under Ramsar convention. Alternanthera philoxeroides is a noxious invasive weed widespread throughout the world. We suggested that al...
A wetland inventory and assessment was made as a basis for development of a national wetlands policy for Colombia (CMWP). Major wetlands were identified from a 1:1 500 000 scale national hydrological map. Of 57 major wetlands in 27 catchments or wetland complexes, wetlands in 16 of these were selected for assessment. Wetland type, ecological status and wetland value for each wetland was scored ...
wetlands as water resources have a special place in the semi-arid plateau of iran and boundary determination is necessary for their effective conservation and conflict resolution among stakeholders that are dependent on these resources. determination of the wetland boundaries should be commensurate with environmental features affecting on it which normally extend beyond water extent. ecological...
Wetlands play important ecological, economic, and cultural roles in societies around the world. However, wetland degradation has become a serious ecological issue, raising the global sustainability concern. An accurate wetland map is essential for wetland management. Here we used a fuzzy method to create a hybrid wetland map for China through the combination of five existing wetlands datasets, ...
Long-term intensive land use/cover changes (LUCCs) of the Yellow River Delta (YRD) have been happening since the 1960s. The land use patterns of the LUCCs are crucial for bio-diversity conservation and/or sustainable development. This study quantified patterns of the LUCCs, explored the systematic transitions, and identified wetland change trajectory for the period 1976–2014 in the YRD. Landsat...
Wetland assessment tools are being developed and employed in wetland monitoring and conservation based on physical, chemical and biological characterization. In wetland biological assessment, various ecological functions have been described by biological traits of an entire species pool that adapts to different types of wetland environments. Since microorganisms play a key role in wetland bioge...
