Doñana National Park wetlands are located in southwest Spain, on the right bank of the Guadalquivir River, near the Atlantic Ocean coast. The wetlands dry out completely every summer and progressively flood again throughout the fall and winter seasons. Given the flatness of Doñana’s topography, the wind drag action can induce the flooding or emergence of extensive areas, detectable in remote se...

In order to guide the management, protection and utilization of wetlands in Shaanxi Province, this paper analyzes summarizes current situation existing problems wetland resources puts forward suggestions accordingly. There are 4 12 types 308,500 hectares. The area proportion various 257,600 hectares river wetlands, 83.50%; 32,300 artificial 10.46%; 7,600 lake 2.46%; 11,000 swamp 3.58%. 77 famil...

Governmental programmes and international agreements to counteract eutrophication have largely not attained agreed objectives (e.g. reduction by half of the anthropogenic nitrogen load on Swedish coastal waters). Important components of such programmes are improved removal of nitrogen in municipal treatment plants and changed agricultural practices. In addition, increased N-removal during runof...

The US Fish and Wildlife Service will make an Endangered Species Act listing decision for the lesser prairie chicken (Tympanuchus pallidicinctus; “LPC”) in March 2014. Based on the findings of a single, Uzbek antelope study, conservation plans put forth for the LPC propose to modify and re-position habitat in the landscape through a series of temporary preservation/restoration efforts. We argue...

Wetlands worldwide are becoming increasingly degraded, and this has motivated many attempts to manage and restore wetland ecosystems. Restoration actions require a large resource investment, so it is critical to measure the outcomes of these management actions. We evaluated the restoration of floodplain wetland vegetation across a chronosequence of land uses, using remote sensing analyses. We c...

Paleolimnology has been used for decades to reconstruct past environments and more recently, to quantify the observed changes. Various organisms preserve in sediment of lakes and wetlands and can be used to reconstruct how a water body and the surrounding landscape looked like and has changed through time. For example, pollen, charcoal, and macrofossils can be used to reconstruct vegetation and...
