Interaction of flooding and salinity stress on baldcypress (Taxodium distichum) Interaction of flooding and salinity stress on baldcypress (Taxodium distichum)

Coastal wetlands of the southeastern United States are threatened by increases in flooding and salinity as a result of both natural processes and man-induced hydrologic alterations. Furthermore, global climate change scenarios suggest that, as a consequence of rising sea levels, much larger areas of coastal wetlands may be affected by flooding and salinity in the next 50 to 100 years. In...

Processes of wetland loss in India Processes of wetland loss in India

Wetlands in India supply crucial human and animal needs such as drinking water, protein production, fodder, water purification, wildlife habitat, and flood storage. Increased appreciation of uses and threats is essential to protect wetlands where justified. Three quarters of India's population is rural, it places great demands on India's wetlands and losses continue to occur. This paper...

Direct denitrification in mangrove sediments in Terminos Lagoon, Mexico Direct denitrification in mangrove sediments in Terminos Lagoon, Mexico

Rates of direct denitrification were measured using 15N isotope tchniques in intact sediment cores from fringe and basin mangroves in Terminos Lagoon, Mexico. Sediments were injected with 15NO3- and the distribution of 15N was measured over time in the head space, overlying water, and sediments. Experiments included an investigation of spatial variation in denitrification rates by...
