Availability of wetlands with low salinities during the breeding season can influence waterfowl reproductive success and population recruitment. Salinities as 2 ppt (3.6 mScm–1) impair duckling growth behavior, mortality occurring above 9 (14.8 mScm–1). We used satellite imagery to quantify amount available water, sampled surface water salinity at Grizzly Island, in brackish Suisun Marsh, three...

An understanding of the modern relationship between diatom species and elevation is a prerequisite for using fossil diatoms to reconstruct relative sea level (RSL). We described distributions from seven transects covering unvegetated subtidal environments forested uplands four tidal wetland sites (Smith Creek, Bone River, Niawiakum Naselle River) Willapa Bay, Washington, USA. compared our datas...

In a scenario of climate change and intensive land-use change, the issue salt marsh degradation caused by global warming soil salinization is becoming more serious. A chamber experiment was conducted to examine responses tuber sprouting seedling growth Schoenoplectus nipponicus variations in temperature regimes (20/10, 25/15, 30/20 35/25°C; 12-h light/dark photoperiod) different concentrations ...

there are two approaches regarding environmental changes. one of the is ignoring them and continuing present trend in future, and the other is identifying these changes and preparing environmental management program in order to control their negative impacts and plan for the improvement of environmental condition. anzali international wetland is one of the protected wetlands in iran which is in...

Many endangered or threatened ecosystems depend on ground water for their survival. Nebraska's saline wetlands, home to a number of endangered species, are ecosystems whose development, sustenance, and survival depend on saline ground water discharge at the surface. This study demonstrates that the saline conditions present within the eastern Nebraska saline wetlands result from the upwelling o...

background: selection of different wastewater treatment methods depends on the kind of wastewater, geographical position of the community, quantity and quality of wastewater and effluent, technology and finance. natural wastewater treatment methods are simple, cheap and acceptable for developing countries specially small and remote countries and wetland is one of these methods. wetlands include...

The Camargue, the Rhône river delta in south of France, has lost 40,000 ha of natural areas, including 33,000 ha of wetlands over the last 60 years, following the extension of agriculture, salt exploitation and industry. Reed development and density in Camargue marshes is influenced by physical factors such as salinity, water depth, and water level fluctuations, which have an effect on reflecta...
