Abstract: The present communication deals with the primary productivity of four wetlands namely, Sohola, Kawoimari, Borbeel and Jamuguri of Kaziranga National Park, Assam. The study revealed higher rate of gross primary productivity and net primary productivity during winter season followed by post monsoon and pre monsoon season. The productivity values suggested that the wetlands are at properly functional state having adequate trophic status at the producer level and can support appropriate consumer population.

Abstract: Technologies for recovering energy from municipal solid waste (MSW) are becoming increasingly established in many countries. This trend derives from a combination of factors which include the potential for economic and environmental benefits and the increasingly held belief that MSW should be viewed more as a resource and less as simply a waste requiring disposal. The objective of this research is to estimate the energy content of municipal solid waste (MSW) generated in Ujjain city of M.P, India, based on its physical composition. Ujjain city provide 150 tons/day MSW generated, Average net calorific value 1103.5 kcal/kg, the net power generation potential is 2.16 kw Ujjain. For energy recovery thermo-chemical and bio-chemical conversion process is used.

Abstract: In the present study heavy metals (Pb, Cu, Fe, Zn and Hg) were analyzed seasonally in the surface waters of river Tawi, Jammu, J & K, India. The samples were collected from three different stations for a period of three years. The results obtained were statistically analyzed using standard deviation (SD), coefficient of variation (CV), ANOVA test and correlation coefficient matrix. The heavy metal contamination of the river was found to occur due to high degree of anthropogenic stress.

Keywords: Aspergillus fumigatus, biosorption, textile effluent
Abstract: Reactive dyes are important chemical pollutants from textile industries. The dye decolorizing fungal strain was isolated from reactive dye effluent contaminated soil. It was identified as Aspergillus fumigatus based on lactophenol cotton blue staining. A. fumigatus could tolerate and biosorp reactive dye under optimized conditions. Maximum decolorization was observed at 3rd day of incubation at 400C and the optimum inoculum concentration was found to be 3% at pH 8. These results suggest that A. fumigatus is more effective for color removal from reactive dye effluent.

Abstract: A study of the water condition of two perennial water bodies, Ikpoba river and Eruvbi stream, Benin, Southern Nigeria was carried out between February and November, 2006; to assess the physico-chemical conditions and the relationship between the health condition of the water systems and their aquatic insect composition. The results show that water quality parameters recorded at Ikpoba river were relatively higher in values and indicated a polluted or stressed water system compared to Eruvbi stream which had relatively cleaner conditions. An overall forty-one taxa of aquatic insects distributed in seven orders were recorded; There were 34 taxa at Ikpoba river and 19 at Eruvbi stream. The results indicated that Ikpoba river was composed largely of insects associated with polluted or stressed conditions compared to Eruvbi stream. The aquatic insect composition at the two locations appear to give an indication of the water condition of the locations and may therefore play an important role as potential bioindicators of the condition of the waters.

Abstract: Dominance, diversity and regeneration status of a moist sub-tropical sal forest in Doon valley was investigated. The results of the study reveal that S. robusta, Ardesia solanacea and Oplismenus compositus were the most dominant species in tree, shrub and herb layers respectively. Shrub layer was the most diverse strata, closely followed by the herb strata. Forest of Asarori are becoming more diverse and heterogeneous. Regeneration studies exhibited reverse ' J ' shaped curve for sal, which signifies good regeneration. But low conversion rate of seedlings to saplings requires proper management.

Abstract: The phytogeographical analysis of the flora of north-central Uttar Pradesh was made during its floristic survey (2004-2009). A total of 944 angiospermic species belonging to 510 genera and 130 families are reported from the study area and these are classified into 13 floristic elements viz.Pantropical (27.12%), Indian (19.6%), Indo-Malayan (17.27%), Neotropical (9.32%), Tropical Indo-African (8.37%), Cosmopolitan (6.04%), Temperate (4.03%), Eurasian (3.28%), Mediterranean (2.54%), Indo-Chinese (0.85%), Austro-Asian (0.64%), Sudano-Rajasthanian (0.64%) and Saharo-Sindian (0.32%). The dominance of pantropical elements in the study area may be due to the adaptation of entrant species to the typical tropical climatic conditions prevailing during major part of the year. The phytogeographical richness of the study area may be due to its unique geographical location where different climatic zones are appearing to be merged with one another.

Abstract: Studies were conducted on the mycorrhiza, mycorrhizosphere and mycobionts of Cedrus deodara. The natural young mycorrhizal roots were creamish white in colour. They show racemose branching which later acquires coralloid appearance. Ectomycorrhizal type of mycorrhiza in Cedrus deodara is confirmed by the presence of fungal mantle and Hartignet in the transverse section of the mycorrhizal roots. 15 fungal species belonging to 9 genera (i.e.Absidia, Aspergillus, Cladosporium, Macrophomina, Myrothecium, Penicillium, Stachybotrys, Trichoderma and Trimmatostroma) are being reported as the mycorrhizosphere isolates of Cedrus deodara. Penicillium was the dominant isolate followed by Absidia, Aspergillus and Cladosporium. Leccinum griseonigrum and Scleroderma verrucosum are being reported as the ectomycorrhizal mycobionts of Cedrus deodara.

Abstract: The population dynamics of Calopepla leayana Latr., a serious (monophagous) defoliator of the commercially important timber species, Gmelina arborea (Roxb.), in Assam, India, was studied in terms of the fluctuation in their abundance in relation to temporal changes in the abiotic factors. Adults as well as larvae were recorded from March to November after which they undergo a brief period of diapause during winter. The population was observed maximum in the month of August when the interacting factors such as temperature and precipitation were high. Statistical analysis of the population data using forward stepwise regression and principal component analysis revealed temperature to be the pricipal component influencing the population.
