Salt marsh habitat loss to vegetation die-offs has accelerated throughout the western Atlantic in the last four decades. Recent studies have suggested that eutrophication, pollution and/or disease may contribute to the loss of marsh habitat. In light of recent evidence that predators are important determinants of marsh health in New England, we performed a total predator exclusion experiment. H...

Uncontrolled releases of Tigris and Euphrates River waters after the 2003 war have partially restored some former marsh areas in southern Iraq, but restoration is failing in others because of high soil and water salinities. Nearly 20% of the original 15,000-square-kilometer marsh area was reflooded by March 2004, but the extent of marsh restoration is unknown. High-quality water, nonsaline soil...

Many species are expanding their distributions to higher latitudes due to global warming. Understanding the mechanisms underlying these distribution shifts is critical for better understanding the impacts of climate changes. The climate envelope approach is widely used to model and predict species distribution shifts with changing climates. Biotic interactions between species, however, may also...

The Deepwater Horizon oil spill affected hundreds of kilometers of coastal wetland shorelines, including salt marshes with persistent heavy oiling that required intensive shoreline "cleanup" treatment. Oiled marsh treatment involves a delicate balance among: removing oil, speeding the degradation of remaining oil, protecting wildlife, fostering habitat recovery, and not causing further ecologic...

The ability of coastal wetlands to keep pace with sea-level rise through vertical accretion and transgression onto adjacent upslope habitats was examined for the following coastal habitats in the southeastern United States: low salt marsh, high salt marsh, brackish marsh, and mangrove forests (fringe, basin, and overwash islands). The relationship between vertical accretion and soil elevation c...

For the past decade, salt marsh management in Florida has been a central issue in attempts to reconcile mosquito control and natural resource interests. Progress has been made in trying to maintain effective mosquito control while protecting and enhancing salt marsh resources primarily due to: 1) efforts by the Florida Coordinating Council on Mosquito Control and its Subcommittee on Managed Mar...

land use of sylhet has changed gradually. this is found from the field survey that in 1970 the area was dominated by marshy land (645.33 katha), vacant land (430.88 katha) and crop land (336.17 katha). by 1988 there was no university in the area. residential area also increased. it covered 39.11 % of total study area. now in 2007 there is a radical change noticed in the area in comparison with ...

The Tuckerton Peninsula is the designated sentinel site of the Jacques Cousteau National Estuarine Research Reserve for the detection and monitoring of climate change effects, most notably sea-level rise and inundation, as well as other natural and anthropogenic drivers of change. It is a 2,000 ha Spartina salt marsh system of state Wildlife Management Lands. Sentinel site infrastructure has be...

The development of sandification process was studied, by monitoring the changes of sediment characteristics, at marsh-sandy land intersections in China's Songnen region. A series of sediment collection plates were deployed in the region; after one year, sediments in these plates were analyzed for changes of mass and chemical characteristics. The sediment flux and the sand content of the sedimen...

A field trials were conducted to assess the helminth parasites of 12 marsh frogs (Rana ridibunda ridibunda) in the Anzali, Astara and Aghbaba regions in the north of Iran in May 1994. Experimental results showed that 83.8% of the Anzali marsh frogs were infected by one or two kinds of metacercarian cysts of digenetic trematodes. The helminth parasites were included Skrjabinoeces breviansa, S. s...
