Abstract: Present study explored the diversity of soil oribatid in four different ecosystems Cachar district of Assam, during July, 2009. Oribatid microarthropod were dominant in homegarden (35.45%), whereas members of Trhypochthonidae were found to be higher in teak plantation (24.03%). Finding suggest that the members of oribatulidae family are most resistant survivor under different land used practices. Density of total cryptostigmatid mites showed decreased order from the undisturbed site to disturbed sites (forests>secondary succession>homegarden>teak plantation). Species similarity of oribatid mite associations in 4 study habitats found that maximum was (45.00%) between secondary succession and forest site and minimum between the teak plantation and homegarden (7.14%). Study consludes that oribatid mites could not be used as an absolute bioindicator of land types.

Keywords: Dalbergia sissoo, Genetic Divergence
Abstract: The variations present in seed and pod traits, genetic superiority and genetic divergence were evaluated for a Seeding Seed Orchard (SSO) of Dalbergia sissoo Roxb, at Bithmera, India sonsisting of 19 progenies from the state of Uttarakhand. The seeds and pods of various progenies in the orchard exhibited significant variability in size, weight and other characters. Significant positive correlations were observed between seed length and weight (P<0.01), seed width and seed weight (P<0.01), seed thickness and seedseed weight (P<0.05), seed weight and germination value (P<0.05), seed lemgth and germination value (P<0.05). The genetic parameters for seed and pod traits also showed a wide range of variations. Hertiability values were found to be over 50 for most of the seed and pod traits, however, only seed weight showed high heritability values coupled with maximum genetic gain. Ward ' s minimum variance dendrogram of progenies of D. sissoo showed three distinct sluster 1 with 6 better progenies, cluster 2 with 10 moderate and cluster 3 with 3 poor progenies. Mean cluster values showed sufficient variation among the clusters for seed weight, germination value and seed length. The possibility of controlled hybridization between better progeny (288) of cluster 1 to the disease resistant progeny (304) of cluster 3 (resistant against deadly Gandoderma lucidum root rot disease of D. sissoo) is also suggested for durther breeding programmes of the species.

Keywords: Urban greening, Regulations, Town planning, Participatory approaches
Abstract: People ' s increasing awareness about loss of green cover and its impact on climate, change, human health and general well-being has brought the issue of urban greening regulations into prominence. This paper health examines the evolution and effectiveness of existing regulatory framework related to urban greening issues in India. The limitations and reasons for only partial success of the existing regulations are studied. The role of various agencies like central government, state governments, muncipal authorities, non-governmental organisations, voluntary agencies and civil societies, in improvement of urban environment is focused. The limitations of the existing regulations related to planting, maintenance and cutting of trees as in existence in various prominent states is analysed. The study reveals that urban greening lacks coordination, focus and priority in planning and implementation at national and regional level. Town planning norms for greening are not followed. The emphasis is primarily on regulating tree cutting rather than involving the stakeholders and civil society in creation and maintenance of additional green cover.

Abstract: India produses huge volume of organic waste annually. This waste comes from agriculture, urban and industrial sources and also from domestic activities. Utilization of this waste material for productivity process is important for both economical and environmental reasons. In the present study an attempt was made to convert the biodegradable green wastes into value addes compost using an exotic earthworm, Lumbricus rubellus. The experiments were carried out in a plastic tray at 50% concentrations of green waste for a period of 60 days. Chemical analysis of worked substrates indicated step-wise increase of nitrogen and phosphorus. The increase of phosphorus and nitrogen were found to be high for green waste undergoing vermicomposting. During the composting period the oraganic carbon decreased from its initial value 7.12% to 5.09%. The results indicate that 50% concentration of waste mixed with bedding material was ideal for the vermicomposting.

Abstract: Application of sewage sludge in agriculture is gaining momentum in many countries and is considered as an efficient waste management option. Sewage sludge is enriched with organic matter, nutrients and trace metals taht can improve plant growth and soil fertility. In the present study an experiment was carried out wherein different concentrations of sewage sludge alone and in combination with different recommended doses of fertilizers (RDF) were to assess to growth performance of brinjal (Solanum melongena var. Local long), a commonly cultivated vegetable of Kashmir valley. The field experiment was carried out during summer (Kharif) 2010 and involved five treatments (T1=Recommended dose of fertilizers: T2=100% Sewage Suldge: T3=75% Sewage Suldge+25% RDF: T4=50% Sewage Suldge+50% RDF: T5=50% Sewage Sludge+25% RDF) each with three replications. The data regarding chemical analysis of sewage sludge and pe and post experiment soil samples with respect to pH, EC, OC, N, P, K, Ca, Mg, Cu, Fe, Mn, Zn, Cd, Ni, Cr, Pb is within permissible limits. The highest yield of brinjal was recorded in T1 (327.67q/ha), followed by 290.21q/ha in T4, Fruit quality parameters viz. carbohydrate and protein content did not exhibit any significant variation between various treatment. On the other hand ascorbic acid content of fruit, foliar photosynthetic pigments (total chlorophyll) all morphological parameters recorded different values in different treatments. Results revealed that application of sewage sludge did not have any adverse impact on fruit quality and can be used for the improvement of plant growth and soil quality. By utilizing sewage sludge in agriculture, environmental degradation can be minimized.

Abstract: Fish are widely used as biological monitors of variations in environmental levels of pollutants. To understand how the fish antioxidant, neural systems respond to the oxidative stress under acute Cd2+ exposures (0.115mg/L, 0.025mg/L, 0.05mg/L, 0.25mg/L), the superoxide dismutase (SOD) activities and lip peroxidation (MDA) contents in the liver and gill, and acetycholinesterase (AChE) activities in the brainof Lutijanus erythropterus were measured respectively. Yhe results showed that the hepatic SOD activities were induced significantly (p<0.01) on 24 and 48 hours of cadmiumexposure, but inhibited on 168 hours (p<0.01), and impaired after 96 hours exposure from the content of MDA except the group of 0.005mg/L Cd2+. While the SOD activities of branchial tissues were earlier than that of the hepatic in response to the cadmium exposure (about 6 and 12 hours), but the oxidative damage to the gills was less than liver on 168 hours exposure. In addition, the activities of AChE in brain tissues were disturbed during 96 hours exposure, and inhibited on 168 hours exposure, which may have relations with the oxidative stress resulted from the cadmium exposure.

Abstract: Nowadays, drug, pulping, textile and other industries are developed in most of the countries and their non save sewages makes many problems for environment. One of the most important dangerous sewage is pigmented sewage, which has complex structures such as azo compounds. In Iran one of the main sources of pigmented sewage is textile manufacturing. Hence, in order to remove colour of this sewage, the present study was conducted to evaluate potential of some bacteria for dya decolourising. To perform this investigation 30 samples from soil and 10 from sewage were collected. All bacteria with potential of decolorization were osolated and identified using biochemical tests. Out of seven different isolated bacteria three were Gram positive and four were Gram negative. Optimization of decolorization for all bacteria was carried out in second step with respect to evalution of bacteria activity at different temperatures (25-45degree C), pHs (5-9) and dye concentrations (0.01-0.04g/L). The results obtained indicated that the best temperature for all bacteria tested was 35 degree C, ph 8.0, and dye concentration 0.02g/L. Therefore, decolorization of pigmented sewage for elimination of dangerous compounds could be possible using bacteria.
