In 2001, a hurricane moved a large sand dune, blocking the sole outlet channel of a mangrove. In the absence of daily tidal flow, the two ponds containing the mangrove vegetation evaporated, the secondary drainage channels were lost, and a salt crust formed on the bed of the ponds. The mangrove lost most of its trees and the remaining suffered from osmotic shock that led to defoliation. Restora...

The McMurdo Dry Valleys of Antarctica are the largest ice-free region on the continent. These valleys contain numerous water bodies that receive seasonal melt from glaciers. For forty years, research emphasis has been placed on the larger water bodies, the permanent ice-covered lakes. We present results from the first study describing the geochemistry of ponds in the higher elevations of Taylor...

To identify the causes of salinization and arsenic contamination of surface water on an embanked island (i.e., polder) in the tidal delta plain of SW Bangladesh we collected and analyzed water samples in the dry (May) and wet (October) seasons in 2012-2013. Samples were collected from rice paddies (wet season), saltwater ponds used for brine shrimp aquaculture (dry season), freshwater ponds and...

present communication deals with the study of four village fish culture ponds (two wild and two managed ponds) from district hisar of haryana, india was undertaken, to correlate the water quality and biological cycles in ponds with fish production. studies have revealed that the ponds are in good trophic status. chlorides, total hardness, calcium, magnesium, biochemical oxygen demand (bod), pho...

samples of water, sediment and shrimp obtained from hatcheries and culture ponds were collected over a period of four months and were analyzed for vibrio parahaemolyticus. samples included the following: two samples of shrimp larva from two hatchery ponds (wlh); 14 samples of water, sediment and shrimp from 14 culture ponds supplied with shrimp larvae from the same hatchery ponds that were obta...
