Abstract: The quality assessment of urban environment is receiving great attention because of its vital importance for population living in large cities of the world. In the modern civilization various anthropogenic activities produce large amounts of wastes and pollutants, which are traditionally disposed mainly in soil, water and air. Such practices continuously emit trace and heavy metals into the components of environment posing a great threat to human health. This study demonstrates that the samples collected from ten sampling stations from the Chitgar River sediments (Tehran , Iran) there is an increasing heavy metal concentration (Cr, Co,Cd,Cu, Pb, Ni and Zn). The study reveals that Pb and Cd are being increasing in the river sediments when studied for their concentrations in a period between May 2007 and May 2008 which could be potentially harmful for the residents of the Chitgar Industrial area.

Abstract: In this study, the anaerobic digestion of different types of organic wastes including swept flour from the floor of flourmills, leftover food and vegetable waste is investigated. The performance of an anaerobic digestor is dependent on the type and composition of the materials to be digested as well as the environmental factors such as pH and temperature. In this work, we studied the performance of an up-flow batch digester by measuring the methane generation for different types of feedstock and tried to correlate the methane generation with basic properties of the feedstock. It was generally found that the digestor well for the range of feedstocks used, with high yield of methane (above 70% CH4 in the generated biogas) in the retention time between one and three days. Efficiency of the digester was measured in term of volatile solid reduction and it was 88.99%.The spent slurry, as the value added out put, was also analyzed.

Abstract: Overgrazing accelerates soil and vegetation degradation in Rangelands . So, Livestock Population Density-i.e. allocated number of sheep per ha- can serve as an index for measuring pressure on range environment. For this purpose, SADRA region has been selected as the study area, where it is located in the upper reaches of MAHARLU basin, Fars Province, Southern Iran. The required data has been extracted from existed records and published reports in ministry of Agriculture, ministry of Energy, Iran Statistics Center and Meteorology Organization. This study is to assess livestock pressure on rangeland in the study area, using Geographic Information System (GIS) tools and a model based procedure.FAO/UNEP Model has been selected for this purpose, which uses a ratio of potential carrying capacity of region to current Livestock Population Density as an Index for livestock Pressure. However, the model has been modified in this study to achieve a better estimation of pressure index according to the actual conditions of the region. Local parameters which have been used to modify this methodology are: annual consumption for livestock unit in the study area, dependency of each livestock to pasture, number of livestock unit for each animal and land use map. Hazard map of pressure of livestock was prepared after overlying and calculating the different parameters in a GIS. According to the results, hazard classes of severe and very severe include about 19% of the study area. Areas, including higher classes of hazard severity have been identified in the eastern part of the region. It is because of low potential of natural rangeland to grow enough forage and also a high number of livestock. Poor soil and harsh climate decrease natural potential of rangeland to grow more forage and to support livestock efficiency.

Abstract: Experiments are carried out to determine simultalneous one-dimensional spatial concentration distribution of spilled petroleum in three soils (sandy, loamy and topsoil) in the horizontal and vertical directions. It is shown that the horizontal spread is very slow and the volume of petroleum spilled has minimal effects on the extent of spread in the horizontal direction. The distance migrated in the vertical (downward ) direction increases significantly as the volume of spilled oil increases. The extent of spread of spilled oil in the horizontal and vertical directions is highest in sandy soil, followed by top soil, and least in loamy soil.

Keywords: Carpinus viminea Wall., Ecology, Regeneration, Lesser known tree species, Uttarakhand , Himalayas.
Abstract: The study species, Carpinus viminea Wall, family Betulaceae, is a medium sized, lesser known, deciduous tree species distributed mainly between 1,800-2,400m elevations in Uttarakhand. It occurs mainly as an under-story species in moist Himalayan temperate forests. The objectives of the present study were to determine the ecological assemblage, seasonal changes, germination and seedling growth. Four study sites between 1,920 and 2,280m altitude were selected for the study. Vegetation characteristics indicated that the species had 33.8 + 10.8 ind ha-1 mean tree density and 1.5 + 0.4 m2 ha-1 mean basal area. Distribution pattern indicated that the species were contiguously distributed. Phenology indicated that leaf fall is completed before seed dispersal. All phenophases delayed towards higher elevations except leaf fall and seed dispersal which is earlier at higher elevation. Seeds germinated from different sites responded differently (P<0.001) to germination. Similarly, germination also varied significantly (F = 50.1, P<0.001) in different conditions. It was greater in seed germinator (T1 ) and least in open nursery conditions (T3 ). Highest germination was found in seeds of maturity periods (P0 ), whereas , seedling growth, biomass and survival were greater at P2 storage i.e. 6 months storage. To increase germination in open nursery conditions seeds can be sown in germination trays by adding lime between February and May. These base line data will help in understanding the ecology and regeneration of C.viminea, and also provide basic information for long term studies in relation to climate change research.

Abstract: In the present study, the storage and sequestration of carbon is described for leguminous trees (Cassia siamia, Dalbergia sissoo) vs . nono-leguminous tree (Tectona grandis Linn.f.) in red lateritic soil of Chattisgarh. Carbon concentrations of different components of eight year old trees were found to be 39.3-42.55 percent, 41.06 - 43.3 percent and 40.74-46.5 percent , 44.4-45.3 percent in leaves, branches, stems and roots respectively. Total storage of carbon ranged from 1,354.7 to 3,079.86 kg ha-1 . Out of the total stored carbon, 70 percent were estimated to be in above ground parts while 30 percent in below ground parts. Storage of carbon was greater in leguminous trees. Similarly, carbon sequestration was also higher by leguminous trees compared to that of non-leguminous trees. Rate of carbon sequestration was a substantial i.e.31 percent for below ground root the same for above ground components was 69 percent. Study reveals the potential of leguminous trees in storage and sequestration of carbon in red lateritic soil and has implications for restoration of degraded land.

Keywords: Rattans (Calamus spp. ) ,Western Ghats of Karnataka, India
Abstract: The rattans of Peninsular India belong to only one genus namely Calamus and 21 species.Twenty species occurring in Western Ghats forests are reported here. The status of C. delessertianus and C.rheedei is uncertain while 15 species are endemic to Western Ghats . Among the five states falling within the Western Ghats , Karnataka has the maximum 13 Calamus species, of which 11 were endemic to the Western Ghats . Three species namely, C.lacciferus, C.lakshmanae and C.prasinus were restricted only to Karnataka region of the Western Ghats . Among the 13 species of Calamus occuring in Karnataka, 12 were found in Kodagu District. Studies were undertaken to determine the status of rattans in some cane-rich forests of Kodagu, Dakshina kannada and Uttara Kannada districts of Karnataka by belt transect method. The sudy has revealed that Sampaje, Karike and Makut in Kodagu District, Subramanya and Charmadi in Dakshina Kannada District and Anantavadi (Honnavar) in Uttara Kannada District were rich in some species of rattans including those endemic to the Western Ghats . The population of C.lakshmanae and C.prasinus (restricted only to Karnataka) was high in Sampaje and Karike forest respectively, however, C.stoloniferus (restricted to Karnataka and Maharashtra) was very high in Makut forest of Kodagu District. In Dakshina Kannada District C.nagabettai was well distributed in about 25 km radius around Subramanya, while Charmadi area has a rich population of C.thwaitesii and fairly good representations of C.prasinus, C.pseudotenuis and C.nagabettai. The population density of C.karnatakensis (restricted to Karnataka and Goa) was very high in Anantavadi forests near Honnavar.

Keywords: Neem, Azadirachta indica A.Juss.,Reproductive Studies, Kinetin Application
Abstract: The in-viva morpho-physiological responses to kinetin application in Neem (Azadirachta indica A.Juss.) were studied during three consecutive annual reproductive flushes from bud development onwards to seed set (prior standardization with endogenous levels). The number of buds and flowers per inflorescence was higher in treated branches as compared to the control. Physiological responses were observed to be kinetin - specific . Year 1 sample proteins, total sugars and reducing sugars measured higher following kinetin at 0.5 mM as compared to kinetin at 0.2m M. The response to year 2 treatments was even better, being significant in 0.5 mM kinetin samples. Year 3 kinetin treatments produced poor flowering response, poor juvenility and low contents of the above compounds as compared to the control. The enzyme assay measuring the activities of invertase, protease, acid- and alkaline phosphatases was consistent with the biochemical responses to the kinetin treatments. In control, a shorter regeneration phase seems to lead to lower productivity in terms of floral inflorescence and fruit set. Therefore, it is suggested that the application of kinetin may regulate the reproductive phase resulting in improved organ-biomolecule production.
