Solid phases of phosphorus fractions in the surface and core sediments were studied to understand the biogeochemical cycling and bioavailability of phosphorus in the Pichavaram intertidal mangrove sediments of India. Total P in surface and core sediments ranged between 451–552 and 459–736 μg g−1 respectively and Fe bound P was the dominant fraction. Low(More)
Aquatic macrophytes are represented by a variety of algal and macrophytic species that occur in many types of habitats. Members of Cyperaceae, Potamogetonaceae, Ranunculaceae, Typhaceae, Haloragaceae, Hydrocharitaceae, Najadaceae, Juncaceae, Pontederiaceae, Zosterophyllaceae, Lemnaceae, mainly represent aquatic plants. These plants are either emergent,(More)
Eutrophic depletion of dissolved oxygen (DO) and its consequences for ecosystem dynamics have been a central theme of research, assessment and management policies for several decades in the Chesapeake Bay. Ongoing forecast efforts predict the extent of the summer hypoxic/anoxic area due to nutrient loads from the watershed. However, these models neither(More)
The distribution, enrichment, and ecotoxicity potential of Bangladesh part of Sundarban mangrove was investigated for eight trace metals (As, Cd, Cr, Cu, Fe, Mn, Pb, and Zn) using sediment quality assessment indices. The average concentration of trace metals in the sediments exceeded the crustal abundance suggesting sources other than natural in origin.(More)
In this study, with the help of the buried slide method, a qualitative observation of the microsociological association in the soil was assessed. Fungal mycelium cohabiting with bacterial forms, rods as well as cocci, individual colonies of Azotobacter-type cells, and certain algae of Hantzschia species were recorded in a central European typical garden(More)
