Abstract: Sporulation-associated mother cell lysis in Bacillus sp. requires the death of spore mother cell that has been hypothesized to be genetically programmed. However, there is lack of conclusive evidence supporting this hypothesis. The present study provides evidence showing expression of programmed cell death (PCD)-specific markers such as activation of caspase-3, externalization of phosphatidylserine (PS) detected by annexin V-FITC binding through flow cytometry, and damage to DNA evaluated by TUNEL assay during sporulation in B.subtillis and B.megaterium.Addition of cell-permeable irreversible inhibitor of caspase-3 was found to inhibit the sporulation process as also the caspase-3 activity and PS externalization. These findings were further revalidated using sporulation-deficient-mutants of B.subtilis, created using chemical mutagenesis. These mutants were found to be deficient in caspase-3 activity as well as the extent of PS externalization. Wild-type B.subtilis cells were found to have extracellular metal-dependent DNAase activity, which decreased in sporulation-deficient mutants. These findings provide evidence for the existence and association of markers of PCD during sporulation-associated mother cell lysis in Bacillus sp.

Abstract: Valeriana jatamansi (family Valerianaceae) is a high-value medicinal plant used in traditional and modern medicine. In the present study, 25 populations (151 genotypes) of V. jatamansi were collected from uttarakhand, India and investigated using nuclear and chloroplast SSR markers. Six nuclear and seven chloroplast polymorphic SSR prime pairs were used to evaluate genetic variability and population relatedness. These primer pairs have generated 59 fragments (26 nuclear, 33 chloroplast) the number of alleles per locus ranged from 3 to 7. Expected heterozygosity of the 25 V. Jatamansi populations was 0.108-0.222 with a mean of 0.165 for nuclear SSR markers and 0.147-0.265 with a mean of 0.215 for chloroplast SSR markers. Based on AMOVA analysis, 6.0% (P = < 0.001) of total genetic variation was found among populations. Nuclear SSR markers exhibited highest genetic diversity in samples collected from 1501 to 1800 m amsl altitudinal range and from pine forest habitat. In case of cpSSR, samples collected from 2101 to 2400 m amsl and grassland habitat exhibited highest diversity. These markers could be helpful in the identification and prioritization of genetically diverse populations/individuals for conservation and utilizing them in genetic improvement of V.jatamansi.

Keywords: Activity-travel survey, combined diary format, design and administration, transportation systems.
Abstract: Studies on travel survey instrument design and administration in the context of Indian cities are limited despite the fact that these aspects of travel survey face unique challenges here when compared to the cities in the developed world. Here we report results of a pilot survey conducted for evaluating the performances, alternative diary formats and survey administration techniques in Bengaluru city, India. The study proposes two diary formats. ' Diary-1 ' is in day-planner format and is a variant of the one day-planner format and is a variant of the one reported earlier in the literature. ' Diary-2 ' is derived as a combination of ' Diary-1 ' and the trip-based diaries widely applied in Indian cities. ' Face-to-face ' , and ' drop-off and pick-up ' methods of survey administration are considered for retrieving the activity travel information o individuals. Evidence appears to be strong that diary-2 is preferable to diary-1 for collecting the travel details of individuals. The comparison of the retrieval methods suggests that the face-to-face method of instrument administration is superior to the drop-off and pick-up method in terms of higher response rates and minimum recording errors.

Keywords: Reproductive, assurance, autogamous, self-pollination across diverse sexual and breeding systems.
Abstract: Pollination becomes a constraint when conspecific plants and/or their pollinators become scarce. Many plant species have evolved autogamous self-pollination as a means of reproductive assurance (RA) under pollination-uncertain environments. So far RA has been studied and discussed largely with reference to self-compatible species producing bisexual flowers. RA seems to have evolved across all other sexual and breeding systems to have evolved across all other sexual and breeding systems-monoecy and dioecy produce bisexual flowers (andro/gyno-monoecy, andro/gyno-dioecy and polygamous conditions) which may provide RA. Similarly, most of the SI species are leaky and do set some seeds upon self-pollination. This phenomenon termed ' partial self-compatibility ' is quite common and does provide RA in SI species. Although dioecy and SI have evolved as obligate out breeding systems, they seem to have reached an evolutionary dead end because of the constraints for outcross pollination. In the light of habitat destruction leading to a reduction in the diversity and density of native pollinators, it is likely that many of the obligate out-breeders tend to shift to mixed mating system in the coming decades. Similarly, obligate mutualism in which each plant species is dependent on one animal species for pollination also seems to have reached a dead end and the trend is to abandon such obligate mutualism as a survival strategy. In the absence of such a change, obligate outbreeders and those with highly specialized pollination system are likely to become endangered or even extinct.

Keywords: Clean energy technology, desalination, membarane distillation, solar photovoltaic cells, thermal efficiency.
Abstract: The present article discusses the application of a new technology using solar photovoltaic (PV) cell coupled with membrane distillation (MD) in the desalination of tap water. Salinity decreases the palatability of water and causes long-term health issues. MD is the most promising technology to provide safe and clean drinking water to households and for other applications in small quantities. It consumes less energy than the existing commercial brackish water reverse osmosis (RO; pressure-driven) desalination technology (48%) used for the production of drinking water. A large population in India relies on tap water, groundwater, surface water, deep well water and municipal water for drinking and domestic utilization. These sources are highly contaminated due to the presence of harmful metals like fluoride and arsenic causing serious health hazards. The present study compares water quality analysis by chemical methods of both RO and solar PV-driven MD technology. The quality of distillate obtained by MD is excellent and this has been proved by the results of chemical analysis of water. Thermal efficiency of MD operating with solar PV cells and others operated purely by conventional mode is calculated and the results are compared. The study shows higher production of drinking water for solar PV-driven MD.

Keywords: Spider feeding, Vespertilionid bat, Kerala, South India
Abstract: Insectivorous bats occupy a relatively safe position in the food web, usually being predated upon only by owls, hawks and snakes. Bats predated upon by spiders are a rare phenomenon and reports on the same in the Oriental region are rare. Only a few chiropterologists and arachnologists have ever seen a bat being predated upon by a spider in the field. Many field biologists and ecologists with special interest in such an ecological relationship between the two taxa have spent decades in the field with little success. There have been only 52 reports on bats being predated by spiders from across the globe over the past hundred years. The infrequency of such reports implies that mortality of bats due to spiders is an extremely rare event, or it may be rarely observed and/or reported.

Abstract: A very severe cyclonic storm, Hudhud, equivalent t o a category-4 hurricane on the Saffir-Simpson hurricane wind scale (SSHWS), originated in the Andaman Sea on 6 October 2014.The cyclone propagated west-northwestward and made landfall near Visakhapatnam, northern coast of Andhra Pradesh on 12 October 2014.The cyclone propagated west-northwestward and made landfall near Visakhapatnam, northern coast of Andhra Pradesh on 12 October 2014.The study area, Gopalpur (Southern coast of Odisha) was in the active influence zone of Hudhud and in close proximity (~260 km north) to the landfall point. This region is an important mass nesting rookery for vulnerable olive ridley sea turtles, which aggregate for breeding in the coastal waters off Odisha from November to May. This region is also identified as a time-series station under the SATellite Coastal and Oceanographic Research (SATCORE) programme coordinated by the Indian National Centre for Ocean Information Services (INCOIS); it is being monitored since 2009.

Abstract: Public-private partnership (PPP) model is now being adopted by many government organizations and research and development institutions. In today ' s economic scenario, the PPP model has been providing strength to the economy and also creating new employment opportunities for economic development. In India, the PPP model has not been popular so far in the area of agriculture and farming. These opportunities are being exploited for the benefits of farmers by the CSIR-Central Institute of Medicinal and Aromatic Plants (CIAMP), Lucknow in the form of a PPP model for contractual cultivation of medicinal and aromatic plants with assured buy-back from the industry at a preferred price. This model has been well adopted by the farmers growing specified crops in partnership with the industry under the technical guidance of the Institute. Artemisia annua, an anti-malarial drug plant, is also cultivated under the PPP model in different parts of the country.

Abstract: Insects have long been ignored in the conservation approaches despite their fundamental roles in terrestrial ecosystems. Considering the lack taxonomic expertise in the diverse insect groups, they are slowly making their way into the biodiversity monitoring studies. Moths belonging to the third largest insect order Lepidoptera are a hugely diverse and functionally important group, which can be a potential bio-indicator group in this present situation of environment degradation. Recent studies have brought this less studied group in this present situation of environment degradation. Recent studies have brought this less studied group in focus for addressing conservation issues and a lot remains to be explored about this fascinating group of insects. In this paper we have shown some preliminary results of two studies done on moth assemblage in Western Himalayan Protected Areas. The studies aim to give an insight about the community structure and distribution patterns within the assemblages which can be a way forward for future bio-monitoring studies.

Abstract: An experiment to evaluate the performance of different varieties of soybean (Glycine max L.Merrill) under two year poplar based agroforestry system was conducted during kharif season in tarai region of Uttarakhand. Four varieties of soybean viz., PS 1042, PS 1225, PS 1347 and PS 1024 of soybean were grown under populous and as sole crop. Germination count/m2 and plant height was not significantly influenced by growth conditions. Growing condition significantly influenced primary branches and number of pods per plant of soybean however; grains per pod, pod length per plant and hundred grains weight (g) were insignificant. Among the varieties, all the yield attributes were higher in PS 1225 except hundred grains weight which was higher in PS 1042.Grain and straw yield were found to be higher in open system (sole soybean) as compared to under shade of poplar showing reduction of 3.94 and 9.86 percent, respectively. Soybean variety PS 1225 recorded highest grain yield (2996 kg/ha) as compared to all other varieties under-storey poplar. However, maximum harvest index was observed in PS 1347 (44.22 %).It can be concluded that soybean crop can be successfully grown under poplar during second year of plantation.

Abstract: Species-area relationships (SARs) were characterized the spatial distributions of legumes and nonlegumes in three sites of the tropical deciduous forests around Jharia Coalfield (JCF) in the eastern part of India. Three 1 ha plots were established one in each site, located 6 to 20 km apart. Each plot was divided into 100 quadrats each of 10 m X 10 m in size. The observed species-area curves were initially steep followed by gradual species accumulation, but none of the sites did the curve reach an asymptote. These curves were best fitted by the power model due to low P value (probability under the null hypothesis), high F ratio (regression mean square over the error mean square) and high Ra2 study, the Z-value decreased with increase in C-value indicating both were simply fitted constant and independent of biotic and abiotic characteristics of the sampling sites. The species-area relationships showed distinct habitat heterogeneity and dispersal limitation for ?all species, legumes and nonlegumes? in the tropical deciduous forests.
