Heavy metal exposure to a migratory waterfowl, Northern Pintail (Anas acuta), in two peri-urban wetlands.

In this study, the heavy metal exposure risk model was employed to assess the exposure risk to a predominantly herbivore waterfowl, Northern Pintail, wintering in two wetland habitats in the Purulia district of West Bengal, located on overlapping Central Asian Flyway (CAF) and East Asian-Australasian Flyway (EAAF). Both wetlands were important staging and roosting grounds for migratory waterfowl for ages. The exposure model was used to quantify the risk of exposure to metals through oral ingestion.

Spatio-temporal study of carbon sequestration through piscicultural practice at East Kolkata Wetland.

The present study focus the variation of carbon concentrations within three trophic level i.e., primary producer (phytoplankton), primary consumers (zooplankton) and secondary consumers (fish) in three selected ponds at East Kolkata Wetland area.
