Abstract: The fairy shrimp Streptocephalus dichotomus has been widely used as food for diverse groups of organisms reared for aquaculture or research purposes. Hatching quality of cysts is of prime importance to aquaculturist and aquariologist. This paper highlights the effect of different feeds on cyst hatching performance of fairy shrimp. Average hatching percentage 86% was recorded that the cysts collected from rice bran fed animals, 74% from cow dung fed animals. Hatching rate was better in the former (24-48 hours) than the latter (48-72 hours). Cyst hatching efficiency considerably varied between 64% (cowdung fed animals) to 71% (rice bran fed animals) suggesting rice bran found to be a better feed.

Abstract: The grasslands of Nilgiris being a species rich vegetations, harbour many medicinal and other economically important plants. Data of floristic composition and utility value and the ecological status of constituent species are the most essential requirements for the preparation of conservation programme for any ecosystem. Considering this fact, four major grasslands namely, Thiashola, Korakundah, Ebbenadu and Wenlockdown were selected in Nilgiris, the Western Ghats for the present study. The study revealed that out of 190 species, encounted in all grasslands, 102 of them are having economic importance. Among them, the species of lower importance value index, higher utility value and threatened nature viz., Anaphalis elliptica, Arisaema leschenaultii, Centella asiatica, Ceropegia pusilla, Curculigo orchioides, Gaultheria fragrantissima, Helichrysum bracteatum, Heracleum rigens, Hedyotis articularis, Kyllinga monocephala, Leucas vestita, Luzula campestris, Oxalis latifolia and Swertia corymbosa are suggested for cultivation and conservation so as to reduce the pressure upon the wild population.

Abstract: When it comes to living a life of convenience - with all electronics and technologies well marketed and easily available to us, it stands as a wall of hindrance to the conservation of Nature. The resources across the globe are made to dry for the sake of giving convenience to the customers and consumers. With the economy blushing over its mind-boggling growth we can easily witness the flushed natural resources, which are making an imbalance in the life support systems. In a way, it is not an exaggeration to say "the economy today is conveniently building the inconvenience for tomorrow". No doubt consumer is teh king in today ' s business scenario. When we have come a long way discussing on the global environmental matters at the Tallberg Forum in Sweden, where 400 delegates from 70 countries had gathered in June, 2007, special signals must be given to the marketers, producers and manufacturers whose convenient products of today will create inconvenience for tomorrow.This paper analyses the current scenario and the effects of environment on the economy, which is so much consumer centric that it consumes all natural rich resources of earth and the future implications of the same. The paper expresses that the quality of life today is extracting resources, which are non-replenishable. Basically it integrates three different facets namely consumerism, environment and economy to understand the future implications of today ' s convenience on tomorrow life style and life-resources. It aims at creating the working models for sustainable development.

Abstract: Studies on air pollution due to burning of fuel wood for cooking purpose is alarming day by day in the tribal villages of Bolangir Dist. of Orissa. About 85 households are selected for the study, which burn about 254 tonnes of fuel wood annually. A negative correlation exists between annual income and fire wood consumption of household (r=-0.11). The heavy use of fire wood is due to its easy availability in near by forest which results in degradation of important woody species of the area having medicinal value. Fuel wood burning also results in release of harmful chemicals which affects the health of the inhabitants to a greater extent.

Abstract: In response to growing concern on global climate change, carbon management in vegetation is inevitable in order to offset the carbon emission in the atmosphere. Trees acts as a sink for the carbon dioxide to mitigate the global climate change. In developing countries like India, due to various need based forest management practices, cultivation, forest fire etc, these has been a continuous loss of original biodiversity. These degradations led to a loss of sequestered carbon of standing biomass. With this back ground, carbon sequestration study is taken in Jnanabharathi campus, Bangalore University. The present study area has a total land of about 449.74 ha with rich vegetation sector and the total amount of both above ground carbon (AGC) and below ground carbon (BGC) was estimated on an average of 54.799 t/ha. The total amount of carbon dioxide assimilated into the trees in terms of both above ground and below ground biomass was estimated an average of 200.931 t/ha. In order to increase the carbon sinks it is necessary to carry out the afforestation and has to protect from the anthropogenic activities.

Abstract: The livestock farming is one of the important component of rural economy in the hills. Increased livestock population has necessitated continuous search for fodder throughout the year. Under these circumstances it has been observed that farm women are bearing the brunt of general scarcity of fuel and fodder at household level. In lean periods, women are required to spend more time to collect increasingly scare resources from far distant locations. An attempt has, therefore, been made to analyse fodder deficit and how it plays a role in farm women activities. Multistage Random Sampling Technique was used for the sample selection. The average livestock holding of the sample farmers were 6.97 of which bovine and ovine were 83.86 and 16.14 percent respectively. The fodder balance analysis by fodder types indicated fodder scarcity for the sample households. Deficit for grass, straw and tree leaf fodder were estimated to be 26.21, 58.78 and 16.15 percent of the total requirement. The overall situation in Jammu & Kashmir projects a 40.30 percent deficit of total fodder requirement. The women spent about 14-18 hours per day in different activities viz. collection of fuel/fodder, animal husbandry, agricultural and household activities. Illiterate, below and above middle educated farm women spent 31.39, 31.69 and 29.80 percent of total time for collection of fuel/fodder where as they spent 17.35, 16.30 and 14.98 percent for animal husbandry activities. The percentage time spent for animal husbandry by farm women was 14.62, 18.06 and 15.95 where as for collection of fuel/fodder it was found to be 31.73, 30.18 and 31.23 percent respectively for the age groups <25, 25-50 and >50 years respectively. The analysis of age of the women and their participation in decision making process for different practices indicated that older women were more involved. It is recommended to cultivate tree and fodder species in nearby areas, so that the farm women can use their time in other productive activities.

Abstract: The paper presents the results of investigation carried out at the Faculty of Forestry SKUAST-K, Shalimar, Srinagar (J&K) to find the effect of moist chilling on germination of Hackberry (Celtis australis Linn.). Mature seeds do not have any deep dormancy. However, they have induced physiological dormancy due to storage. Chilling treatment of seed for four week showed maximum germination of 73 percent as compared to control. Nine presowing treatments were tried for improving the germination of Celtis australis. Best germination was observed in (stratification for one month at 5 + 1oC + GA3 200 ppm) treatment and best early growth parameters were observed in (GA3 200 ppm) treatment followed by stratification + GA3 200ppm, GA3 100 ppm and only stratification for one month at 5 + 1oC.

Abstract: A field experiment was conducted in Shahapur Tahasil (study area is situated at the height of 174m from sea level, latitude 19o 26.874, longitude 73o20.964, near Liberty Oil Mill) from various villages. The area is facing the problem of low yield because of low fertility, seasonal cropping etc. Hence there is need to analyze soil to check the proportion of various nutrients. Quality and quantity of crop depends upon soil contents but the contents do not remain same all over the nation, they change according to the fertility of soil and atmosphere. Hence soil samples are collected from various villages of Shahapur Tahasil and analyzed by standard methods. On the basis of soil analysis reports soil contents, fertility of soil, type of crop to be taken etc are decided. And also quantity of manure (like dung) and various chemical fertilizers are decided. Some remedies are also suggested to increase the fertility of soil.

Abstract: Planktons forms the natural food for Indian major carps (Catla catla, Labeo rohita and Cirrhinus mrigala) and exotic carps (Ctenopharyngodon idella and Hypophthalmichthys molitrix). As a natural diet, plankton enhances fish growth and production. However, some members of plankton like cyanophycean and euglenoid genera are noxious, which lead to poor growth or even death of fishes. In culture practices, ferilizers are added to maintain rich plankton populations. Fertilization often results in the production of a diverse assemblage of both phyto- and zooplankton. In order to assess the effect of different plankters on fish production, a study was carried out in different carp culture ponds of Krishna district, Andhra Pradesh, India. In fish ponds under study, phytoplankton were mostly represented by Cyanophyceae, Chlorophyceae, Bacillariophyceae, Euglenineae and Dinophyceae, and zooplankton by Rotifera, Cladocera and Copepoda. The relationships among different groups of phyto- and zooplankton and their influence on fish production were discussed in the light of the existing literature.

Abstract: Quantifying the noise level for purpose of determining whether they exceed the local legally accepted or adopted limits is a complex but crucial task. The mathematical modeling was used to predict the traffic sourced noise pressure levels for the Mughal Road (Jammu & Kashmir), and it is inferred that the forthcoming or expected traffic would generate a noise level of 83.48 dB in the vicinity of the highway, and the distance were the sound pressure level will drop at 50 dB is expected to be 2200 meters from the edge of the highway, as long as the impact of other factors such as altitudinal gradient, etc. are considered as non significant. The sound pressure drops at a sudden significant within the first 50 meters of the vicinity of the road and then the drop in pressure level with the progressive distance continues very slowly and assumes a nearly uniform rate of decline from 1200 m onwards.

Abstract: The antifungal assay was carried out using three organic solvents namely diethyl ether, acetone and methanol. A total of 6 seaweeds from Vellar and Uppanar estuary were tested against 7 pathogens. In the present investigation, only moderate and trace antifungal activity was noticed against Candida albicans, Microsporum gypseum and Mucor sp. and none of the algal extracts were active against the genera Aspergillus and Rhizopus. The order of antifungal activity was as follows Gracilaria verrucosa > Cladophora glomerata>Rosenvingea intricata> Enteromorpha clathrata. This may be due to the lack of plant protein, often responsible for antifungal activity or due to low level of specific metabolites in the extracts or may be because of the different solvents used for extraction. The seaweed samples from Uppanar estuary were noted to show more activity towards tested pathogens when compared to seaweeds from Vellar estuary during the present investigation.
