Abstract: Cannabis sativa L. (family cannabaceae) is a medicinal and aromatic plant growing all over the world. The present study aims to investigate the essential oil composition and antimicrobial activity of C. sativa from the foothills of northern India. The hydro distilled essential oil of C. sativa was studied by capillary gas chromatography /flame ionization detector (GC-FID) and GC-mass spectrometry (GC-MS) and evaluated against nine pathogenic bacterial strains using disc diffusion assay. A total of 57 constituents representing 90.5-93.1% of the total oil compositions were identified. Major constituents of the essential oil were (E) -caryophyllene (19.6-26.1%), limnonene (4.1-15.8%), caryophyllene oxide (2.0-10.7%), (E)-?-farnesene (4.8-8.5%), ?-humulene (5.4-7.8%), ?-pinene (0.7-7.7%),myrcene (0.8-6.0%), terpinolene (0.2-6.0%) and ?-selinene (1.8-5.4%). The oil showed moderate to good activity against most of the tested Gram-positive bacteria (staphylococcus aureus (MTCC2940), staphylococcus aureus (MTCC96) and streptococcus mutants ). The oil also showed moderate activity against a Gram-negative bacterium, salmonella typhimurium. The chemical composition of the examined c.sativa essential oil was quite different from earlier reported compositions. The oil possessed moderate to good activity against most of the tested bacterial strains.

Keywords: Bats, echolocation, species diversity, wet evergreen forest.
Abstract: The Western Ghats of India is among the top 25 biodiversity hotspots in the world. About 43% of the reported 117 bat species in India are found in this region, but few quantitative studies of bat echolocation calls and diversity have been carried out here thus far. A quantitative study of bat diversity was therefore conducted using standard techniques, including mist -netting, acoustical and roost surveys in the wet evergreen forests of kudremukh National park in the Western Ghats of Karnataka. A total of 106 bats were caught over 108 sampling nights, representing 17 species, 3 belonging to Megachiroptera and 14 to Microchiroptera. Acoustical and roost surveys added three more species, two from Microchiroptera and one from Megachiroptera. Of these 20 species, 4 belonged to the family Pteropodidae, 10 to vespertilionidae, 3 to Rhinolophidae, 2 to Megadermatidae and 1 to Hipposideridae, 2 to Megadermatidae and 1 to Hipposideridae. We recorded the echolocation calls of 13 of the 16 microchiropteran species, of which the calls 13 of the 16 micro chiropteran species, of which the calls of 4 species (pipistrellus coromandra, pipistrellus affinis, pipistrellus ceylonicus and Harpiocephalus harpia) have been recorded for the first time. Discriminant function analyses of the calls of 11 species provided 91.7% correct classification of individuals to their respective species, indicating that the echolocation calls could be used successfully for non-invasive acoustic surveys and monitoring of bat species in the future.

Keywords: Anthus nilghiriensis, endemic bird, montane grasslands, shoal forest, threat status.
Abstract: Montane grasslands in India face threats from habitat modification and climate change, but have received little conservation attention. In the Western Ghats, 55-80% of this habitat has been converted to commercial and non-commercial plantations. We examine the the distribution of a range-restricted, grassland -endemic bird, the nilgiri pipit Anthus nilghiriensis through both field work and literature survey. We combine our mist-net-based capture data with museum records that appear to indicate a smaller distributional range for the species is limited to grasslands above 1900 m. Using GIS methodology, we estimate the area of this habitat to be only 441 sq.km. spread over just two mountain -tops, our analyses indicate a drastic reduction from the presently projected distribution, making this species one of the most restricted -range birds in India. We discuss potential causes for this discrepancy, including misidentification, which may mislead potential conservation action for such threatened birds. We propose palaeo climatic changes to be the cause for the present distribution limit to the two large mountains (Nilgiris hills and Anamalai-palani hills), while anthropogenic habitat modifications may limit the distribution at a finer scale within these mountains. Given the combined effect of historical large-scale landscape modification in this region and the possibility of climate change affecting this species , the Nilgiri pipit and its habitat appear to be under considerable threat and the bird requires urgent conservation measures ,starting with an elevation of I UCN threat level to ' Endangered ' .

Keywords: Diclofenac ban, vulture conservation, pharmaceutical threats.
Abstract: To sustain itself, an ecosystem needs scavengers as much as it needs producers. Despite this, although producers are widely recognized, appreciated, researched and protected by us, scavengers are given less importance. For instance, it was only after vultures started declining drastically in the Indian subcontinent that their scavenging lifestyle, like soaring flight, keen eyesight and extremely low pH of gastric secretions. More than half of the vulture species is on the brink of extinction, with the most dramatic declines observed recently in the Indian subcontinent .While numerous factors threatened vultures, persecution and poisioning have contributed to their decline. In India, Gyps vultures have declined by 99% due to unintentional poisoning by the veterinary drug diclofenac.

Keywords: Carbon footprint, Co2 emission, energy consumption, lifecycle analysis, marine fisheries.
Abstract: The contribution of marine fisheries in Visakhapatnam at all stages of its life cycle to climate change during 2010-2012 was studied by determining its carbon footprint.pre-harvest phase consisted of vessel construction and maintenance and provision of fishing gear; harvest phase included harvest from mechanized and motorized craft and post- harvest phase involved fish transportation and fish processing. The functional unit selected was 1 Kg of marine fish to the consumer. Fuel and electricity consumption was 0.481/Kg and 0.255 k Wh/kg of fish. The c and CO2 emitted were 0.382 kg c/kg and 1.404 kg Co2/Kg of fish. The highest consumption of energy and the highest emissions of CO2 were observed from the harvest phase. The fuel and electricity consumption and C and CO2 emissions were high for mechanized landings and low for motorized landings .Reduction in energy consumption and subsequent emissions is possible in mechanized craft by increasing the fuel efficiency of marine diesel engines, controlling craft speed, using large propeller with lower revolutions and reducing the craft drag.

Abstract: In Drosophila bipectinata female remating with respect to productivity and sperm displacement was studied by employing two mutant strains and a wild-type strain. The comparison of productivity between once-mated (control) and remated females is significantly higher than that of once-mated females in all the crosses showing increased productivity after remating. The P2 values (proportion of second male progeny produced after remating ) were calculated to test sperm displacement in each cross of remated females ,which range from 0.60 to 0.67 extending the evidence for sperm displacement in D. bipectinata .

Abstract: The complexity of molecular compositions of ayurvedic preparations makes their classification or quality monitoring a difficult task. Classification of aqueous -based ayurvedic preparations with commonly used techniques such as Fourier transform infrared and near infrared spectroscopy is more difficult due to strong interferences from water signals. In the present work, by taking an aqueous -based ayurvedic preparation (jirakadyarista) as a test case, It has been shown that a simple, fast and efficient procedure for the classification of such preparations can be achieved by combining synchronous fluorescence spectroscopy with chemometric methods such as principal component analysis (PCA)and partial least square discriminant analysis (PLS-DA). The PCA and PLS-DA modes obtained were found to be sensitive and specific in classifying the jirakadyarista samples.

Keywords: Climate change, maximum entropy, rubber plantations, species distribution model.
Abstract: In a warming world, species distribution models have become a useful tool for predicting plausible shifts of a species occurrence enforced by climate change. Using maximum entropy (Maxent) model, we analysed present and future distribution patterns of rubber tree (Hevea brasiliensis) in two distinct biogeogrphical regions of India: the western Ghats having a good distribution of rubber plantations at present and the Brahmaputra valley, where rubber trees are recently being cultivated . The model -derived suitable regions of the Western Ghats and Brahmaputra valley provided good conformity with a satellite-derived rubber plantation distribution map. Annual range of temperature and mean temperature in the coldest months, temperature seasonality and rainfall in the warmest quarter would be the major decisive variables in the in the distribution of this species as revealed y the area under receiver operating curve. Interestingly, we predict that more areas will become suitable for rubber cultivation by the middle of the 21st century in the Brahmaputra valley, while some areas under current cultivation may become partially unsuitable for this species in the Western Ghats. This result can help planners in deriving a comprehensive rubber plantation policy for India considering the existing land-use scenarios.

Keywords: Craters, Moon, Tectonic features, volcanic flows.
Abstract: It is generally believed that the Moon became internally dead ~ 1 b.y. from the present, and only old (>~1b.y.) Volcanic flows forming largely the mare basins are known to occur. The old volcanic landforms stand largely obliterated and flows studded with impact craters. However, recent findings have indicated global presence of young thrust faults on the Moon, escape of gases from the interior and also predicted the presence of partially molten lower lunar mantle and core. Here, we have used high -resolution datasets from NASA ' s LRO, Kaguya of JAXA and ISRO ' s chandrayan-1 missions to examine the characteristics and origin of multiple relatively fresh, Coaxial , superposed viscous flows spotted inside the Lowell crater on the far side of the Moon . Various considerations apparently rule out the possibility of these melts being derived from nearby areas. An associated likely source crater and affecting different ages but emanating from the same crater and affecting different flows have also been located-exhibiting tectono-volcanic relationship . These features provide evidences of likely volcanic activity in the region not too far in the past, are consistent with recent results that the Moon may not be internally dead, and thus have implications to the thermal history and present -day geologic nature of the Moon.

Keywords: Amphibians, conservation, Myristica Swamps, reptiles, species abundance distribution, trees.
Abstract: The species abundance distribution (SAD) utilizes all the information gathered in a community and is the most complete mathematical description of the data. Myristica swamp forests are an endemic, highly fragmented ecosystem, naturally restricted due to systematic destruction and the special abiotic conditions required for their survival. Species diversity of amphibians, reptiles and trees in the Myristica swamp forests of southern Western Ghats in Kerala was documented using standard protocols for two years. Conventional species abundance distribution models could not be fitted into the data sets of this study. Graphical representations of the distribution models could not be fitted into the datasets of this study .Graphical representations of the distribution of the data set suggest that existence of multiple peaks on a log scale does not reject the universal hollow curve law on the arithmetic scale, but it will reject all SAD models producing unimodal curves. Various studies using SAD as a tool for community and ecosystem studies were reviewed and it was found that the presence of many species of intermediate abundance and decrease in rare species in our datasets could be an indication of natural distributions moving apart under disturbance and enrichment. Deconstruction and identification of resident and transient groups was done. We suggest that the Myristica swamps, which are situated in an area with high potential for rare species, may be in a transition due to disturbance and fragmentation. Ground truthing and previous studies already indicate these swamp forests as highly fragmented and disturbed.

Abstract: The chemical sensing behavior o the carbon nanotube and graphene-based sensors for detecting various chemical analytes is presented in this article. A focus on detection mechanisms has been provided to assess their relative potential under different environmental conditions. The performance of these two carbon allotropes is compared based on their sensitivity towards various types of electron donating and accepting molecules. Although these carbon materials still have to meet crucial challenges in fabrication and optimization, continued progress in this field may lead to a sensor with superior sensitivity for a wide range of applications.

Abstract: In this article, intellectual property (IP), its various types and the rights of patentee are defined. Challenges for Indian IP professionals at academia and IP firms are also identified. India ' s preparedness in IP matters is almost pathetic, which has further been compounded by factors such as excessive filing by non-Indian entities, the myths Indian Entities (IEs) are shrouded in and strategy by non-practicing entities. Role of Indian academia in preparing the IP ambience has been highlighted .IEs have been advised to adopt correct IP practices. The preparedness of IEs in the IP matters has been analysed and the gap areas have been identified. Need for a fully functional IP cell at IE has been established. Such an IP cell will provide the required support to the inventors and help IE handle its IP obligations. Technology Transfer Office can be a possibility after successfully operation of IP Cell at IE.

Abstract: Polyembroyny, having more than one embryo in a single seed, was first discovered by Leeuwenhoek in 1719 in Citrus. Later, various researchers reported and described it in detail .The additional embryos in polyembryony are either Zygotic or non-zygotic origin and the latter is also known as adventitious polyembrony. Adventive polyembryony is reported from a number of tropical trees species, viz. Garcinia, Citrus, Shorea, Prunus and commiphora. The degree of polyembryony varies greatly species and also within the cultivars of the same species as revealed in Citus.
