The ability of Scirpus littoralis to take up and translocate five metals- Mn, Ni, Cu, Zn and Pb from fly ash dosed and metal spiked soils were studied under waterlogged and field conditions for 90 days. Scirpus littoralis accumulated Mn, Ni, Cu, Zn and Pb upto a maximum of 494.92, 56.37, 144.98, 207.95 and 93.08 ppm dry wt., respectively in below ground organs (BO) in 90 days time. The metal content ratios BO/soil (B/S) were higher than shoot/soil ratios (T/S) for all the metals, the highest being for Ni. Metal ratios BO/water (B/W) were also higher than shoot/water (T/W) ratios but the B/W ratio was maximum for Zn. The changes in nutrient status (N, P) in soil water and plants were also studied at interval of 30 days. The Pearson's correlation between metal uptake and N, P uptake were calculated. All the metals except Ni showed negative correlation with nitrogen but they were all non-significant. However, P uptake showed positive correlations with all the metals and all were significant at 1% confidence limit.

[more] Realization of the rapid loss of species due to habitat destruction has brought into focus the multiple dimensions of biodiversity and led to the Convention on Biological Diversity. The biodiversity of inland aquatic ecosystems has just started receiving some attention. Wetlands whose conservation and wise use has been promoted by the Ramsar Convention since 1971, are among the most threatened ecosystems because they are directly destroyed as well as bear the impacts of all anthropogenic activities in their watershed. Many of the well-known wetland values are related to their biodiversity. Yet, our understanding of their biodiversity is very poor. This introductory chapter elaborates the background of the book and sets the stage for discussion of various issues concerning the biodiversity in wetlands.
