Turkey is a country rich in wetlands (250 wetlands, approximately one million hectares). As it is in many countries, the wetlands in Turkey are threatened by the agricultural activities, loss of habitats due to these activities and by pesticide contamination. After 1940, large quantities of pesticides, especially DDT were used intensively against mosquitoes and pests in most of the wetlands in ...

Temporary wetlands dominate the wet season landscape of temperate, semi-arid and arid regions, yet, other than their direct loss to development and agriculture, little information exists on how remaining wetlands have been altered by anthropogenic conversion of surrounding landscapes. This study investigates relationships between the extent and type of habitat transformation around temporary we...

to determine the prevalence of animal fascioliasis in coastal regions of the caspian sea, during 2006-2007, a total of 2368 faecal samples were collected from sheep (n=1250), cattle (n=975) and horse (n=143). the samples were obtained directly from the rectum of animals. floatation method was performed for determination of egg per gram of faeces (epg). our findings revealed the presence of fasc...

The values of wetlands are commonly known among the general population— waterfowl habitat, sport fisheries, timber, recreation, and so forth. More importantly, ecological wetland functions such as nutrient cycling and mitigation (filtering) of pollutants are becoming more widely recognized, especially in the agricultural community. So then what is the importance of agriculture and wetlands? Alt...

Wetlands are valuable ecosystems that provide many valuable services, yet many of these important ecosystems are at risk because of current trends in climate change. The Prairie Pothole Region (PPR) in the upper-midwest of the United States and south-central Canada, characterized by glacially sculpted landscapes and abundant wetlands, is one such vulnerable region. According to regional/global ...

Constructed subsurface flow (SSF) and free-surface flow (FSF) wetlands are being increasingly implemented worldwide into wastewater treatments in response to the growing need for microbiologically safe reclaimed waters, which is driven by an exponential increase in the human population and limited water resources. Wastewater samples from four SSF and FSF wetlands in northwestern Ireland were te...

Invasive species are a known and growing threat to native ecosystems and the services they provide, and it is widely accepted that human activities contribute substantially to their spread. In a study of fifty-two north Mississippi wetlands, approximately 10% of the vascular plant species encountered were non-native, and 60% of the wetlands surveyed contained at least one plant species consider...

Water quality index is considered as an effective indicator of the health of water. With the climate change scenarios the quality determination of wetlands becomes a burning issue. In India different wetlands have different set of regional and local teething troubles regarding their health. In the present paper a framework is set for water quality assessment and comparison between four wetlands...

Executive Summary This project sought to identify a number of Missouri River floodplain wetlands for monitoring and assessment of wetland condition using several assessment tools developed in this and a previous project entitled " Assessment of Floodplain Wetlands of the Lower Missouri River Using an EMAP Study Approach " (A number of randomly selected wetlands were identified using the probabi...

The toxicity and estrogenicity of a final treated municipal effluent was examined while flowing through a constructed wetland in north-central Texas, USA. Fish data were collected, and a baseline wetland characterization was performed to assess wetland treatment potential for these effluent properties. Vitellogenin (VTG), gonadosomatic index (GSI), hepatosomatic index (HSI), and secondary sexua...
