We tested the hypotheses that species with greater mobility and/or higher reproductive rates are less sensitive to habitat loss than species with lower mobility and/or reproductive rates by conducting a meta-analysis of wetland vertebrate responses to wetland habitat loss. We combined data from 90 studies conducted worldwide that quantified the relationship between wetland amount in a landscape...

The National Park of Las Tablas de Daimiel in Central Spain is a wetland area of great value regarding biodiversity and wildlife habitat. This type of ecosystem is unique within a semi-arid climate and especially sensitive to degradation processes caused by growing pressure on natural resources (agricultural practices, groundwater depletion and land use change) as well as climatic changes. The ...

Wetlands are most important and valuable ecosystem for maintaining biodiversity on the planet. In present scenario wetlands are vulnerable to climate change and land conversion activities like agriculture and urbanization. Due to their important fine temporal scale monitoring of sensitive wetlands are required. For this purpose few tools are specified to monitor the wetland at landscape scale. ...

This paper presents a scenario-based approach to strategic environmental assessment (SEA) for wetland trend analysis and land use and land cover (LUC) modeling in an urban environment. The application is focused on the Saskatoon urban environment, a rapidly growing urban municipality in Canada’s prairie pothole region. Alternative future LUC was simulated using remote sensing data and city spat...

The functions of wetlands are water supply, livestock supply, wildlife refuge, employment and human uses, research and training, climate adjustment and recreational services. The purpose of this study is to estimating the economic value of Gandoman international wetland with area of over 1100 hectares in 2017 and provide it to the relevant authorities for its further protection. Data collection...

Mechanisms of natural attenuation of arsenic (As) by wetland plants may be classified by plant uptake and adsorption and/or co-precipitation by iron (oxy)hydroxide formed on the root surface of plants or in rhizosediment. A natural Cattail (Typha spp.) wetland impacted by tailings containing high levels of As from the Myungbong abandoned Au Mine, South Korea was selected, and the practical capa...

a r t i c l e i n f o The increasing fragmentation and degradation tendency of estuarine wetlands due to rapid urbanization in coastal areas exert the urgent need to quantify the structural characteristic of wetland network, which involves the fragmentized wetland patches for wetland restoration and conservation. Although wetland networks have already been used for conservation planning on a re...

PURPOSE: One of many potential uses of the hydrogeomorphic (HGM) approach for assessing wetland functions is the monitoring of newly restored wetland sites to determine how quickly wetland functions develop and whether function-based mitigation objectives are being met. This technical note presents a case study of the application of the Western Kentucky Low-Gradient Riverine Guidebook to monito...

Wetland, as one of the weakest ecosystems in the world, is deteriorating rapidly in many regions. Longfeng wetland is the biggest urban wetland in China, located in the inner of Daqing city, Heilongjiang Province. It is divided into two areas by Wolong road, the east is provincial natural reserve and the west is unprotected. This paper describes a remote sensing change detection approach used t...

Gavkhouni wetland located in the center of Iranchr('39')s Plateau is one of the important habitat for native flora and fauna. The present study aimed to evaluate change trend of vegetation types and Soil Moisture Index in Gavkhouni wetland since recent 16 years. Vegetation types were identified via field visitation during 2011-2017 and the maps were generated in ArcGIS 10.5. SMI is derived us...
