    View Abstract
    Streamflow trend is a robust indicator of the changes in meteorological inputs at a catchment scale and provides vital information about the seasonal and long-term storages of water in soil, snow and glaciers. Due to the mountainous terrain of the Kashmir Himalaya, the network of meteorological observatories is very scanty and inadequate. Therefore, the trends in the observed streamflows, temperature and precipitation shall provide a composite indication of the impact of changing climate at the basin level. Mann-kandall test was used to determine the trends in the annual, seasonal streamflows and meteorological variables (temperature and precipitation) from 1980-2010. Pearson correlation test was used to analyze the relation among the three hydro-meteorological variables. Results from the four observation stations revealed that the Jhelum streamflows have decreased in spite of the increase in the glacier-melt due to the rising temperature. Overall, the precipitation has marginally decreased in the Kashmir valley during the observation period. A good correlation was observed between the winter precipitation (snowfall) and spring streamflows at all the observation stations. The results indicated that the depleting streamflows in the Jhelum river is influenced by the seasonal precipitation and increasing temperature and consequent glacier loss in the Jhelum basin. It is believed that, if, the trend continues, the depleting streamflows will have adverse impact on the water-dependent sector like agriculture, horticulture, and tourism in the Kashmir Himalaya.

    Herbal medicines are being used by about 80% of the world population primarily in the developing countries for primary health care. They have stood the test of time for their safety, efficacy, cultural acceptability and lesser side effects. The chemical constituents present in them are a part of the physiological functions of living flora and hence they are believed to have better compatibility with the human body. Bergenia ciliata is one of the important medicinal plants of Kashmir Himalaya. The plant is reported to contain numerous phytochemicals which show diverse medicinal properties. The bioactive compounds which were present in the methanolic extracts of rhizomes and leaves of B. ciliata include alkaloids, amino acids, carbohydrates, glycosides, phenolics, steroids and tannins. However, the extracts showed negative results for terpenoids, flavinoids and saponins.

    View Abstract
    Pollution of water bodies affects all the biotic communities including fish. The chemical fertilizers and pesticides are the main sources of water pollution. The general effects of water pollution on fish may be considered as physical effects, oxidation effects, toxic chemical effects etc. As fish is excellent indicator of water quality and parameters such as fish population size, growth rate, condition factor and diversity are also indicative of the total health of water. Toxic chemicals generated through man‟s industrial agricultural and domestic activities eventually reach aquatic environment and cause a major threat to the inhabiting organisms. Since the aquatic environment is fragile and hence sensitive to the toxic effects of chemical pollutants including hydrophobic pollutants. Pollutants such as pesticides are known to alter the behavioural pattern, growth and reproductive potential and resistance to disease of aquatic organisms by effect on a variety of biochemical and physiological mechanisms. The toxicity of sodium cyanide (free cyanide) to the fresh water fish, C. gachua was studied using static bioassay method. The LC50 in 96 hours was found to be 33μgL-1. Behavioural changes when exposed to lethal concentration of sodium cyanide showed increased opercular movement, increased surface behaviour, loss of equilibrium, change in body colour, increased secretion of mucus, irregular swimming activity, rapid jerk movement, partial jerk and aggressiveness. The swimming behaviour was in a cork screw palter, rotating along horizontal axis. In sub-lethal treatment, the schooling behaviour of the fish was slowly disrupted, the ventilation rate was increased. The fish C. gachua at 21st days of exposure exhibited balanced swimming and active feeding and behaved in normal way. Hence, oxygen consumption was decreased in lethal concentration (-22.64 -70.13%), but in sub lethal concentration decreased trend was improved and reached normal level at 21st day (-25.10-2.19). Alterations in oxygen consumption may be due to respiratory distress as a consequence of impairment in oxidative metabolism. Fish in sub lethal concentration were found under stress but that was not fatal.

    The present study has evaluated the potential of the plant E. arvense against the mutagenic effects induced by cyclophosphamide (chemotherapeutic agent) in the bone marrow cells of mice using the CA in vivo as the biomarker. The study was performed following 3 protocols: pre-treatment, simultaneous treatment and post-treatment with the aqueous extract of the plant. The results demonstrated that the plant extract was not mutagenic and has a protective effect against the mutagenicity induced by cyclophosphamide. Because of its ability to prevent chromosomal damage, E. arvense is likely to open an interesting field concerning its possible use in clinical applications, most importantly in cancer as a chemo preventive agent.

    European Blackberry (Rubus fructicosus L.) is a prickly, sarmentose shrub found in a variety of habitats including woodlands, hedgerows, gardens, roadsides, wastelands, etc. The objective of the present study was to evaluate the dye yielding potential of the fruits of European Blackberry of Kashmir valley. The stability and colour quality of pigments (anthocyanins and carotenoids) were assessed by quantifying the pigments and recording their colour quality at 10 days interval at 0, 10, 30, 40, 50, 60, 70, 80 and 90 days after collection under ambient and refrigerated storage conditions. Results revealed that the total anthocyanin content (mg/100 g) and total carotenoid content (mg/100 g) were in a range of 521.04 to 1109.97 mg/100 g and 0.125 to 0.943 mg/100 g. Highest pigment content was recorded during 0 days of storage. Under ambient conditions plant material perished due to fungal attack. With increase in days of storage pigment content decreased in both plant material as well as extract. Pigment degradation was more in the plant material as compared to the plant extract. Colour quality of the plant species changed with increase in days of storage. From the present study it was concluded that European Blackberry fruits contained superior levels of anthocyanin content, thus it can be used as a raw material for extraction of reddish to pink edible food colours.

    View Abstract
    Climate change is caused by emission of greenhouse gases (GHGs) through anthropogenic activities including land-use change, deforestation, biomass burning, draining of wetlands, soil cultivation and fossil fuel combustion. Consequently, the concentration of atmospheric greenhouse gases and their radiative forcing have progressively increased with increase in human population, especially from the onset of industrial revolution around 1850. Thus, unless necessary steps are not taken to reduce CO2 emissions by increasing carbon sinks in terrestrial ecosystem alone, it is not possible to stabilize or reduce concentration of CO2 in the atmosphere.

    Little information exists on breeding Indian moorhens (Gallinula chloropus) in lakes and wetlands of Kashmir Himalaya. We studied the nesting ecology of Indian moorhens inhabiting Hokersar and Eastern foreshore area of Dal Lake. Nesting sites were dominated by Sparganium erectum, Butomus umbellatus, Typha angustata, Phragmites australis and Salix tree species and adjacent foraging areas were primarily composed of Nympheae spp, Nymphoides peltata, Trapa bispinosa, Salvinia spp, Myriophyllum verticillatum, Potamogeton spp, Azolla sp. The mean water depth surrounding nests was 70 cm in Hokersar and 96 cm in Eastern foreshore area of Dal Lake. The population of common moorhen sighted in Hokersar was greater than the population found in the eastern foreshore stretch of Dal Lake as evidenced by the number of birds and nests located from this area.
