Planning for human-carnivore coexistence requires detailed understanding of the ecological and sociological circumstances associated with conflict, particularly in multi-use, human-dominated landscapes. We investigated the influence of socio-ecological factors on human-sloth bear (Melursus ursinus) conflict in a human-dominated landscape of Balasore Wildlife Division, eastern India. We examined human-sloth bear conflict data from 12 years (2002-2013) and assessed the attitudes of the people toward sloth bears through semi-structured interviews with 350 people. We recorded 167 human-sloth bear conflict incidents, including 201 human casualties (4 deaths, 104 permanent injuries, and 93 minor injuries) and 7 retaliatory killings of sloth bears. More human-sloth bear conflict occurred during the monsoon season (Jul to Oct) than in other seasons. Monsoon is the peak growing season, when villagers spent more time outdoors farming, including near forest. In addition, lack of toilets in the villages may increase vulnerability of humans to sloth bear attacks. Most people considered sloth bears to be unpredictable and dangerous, which suggests protection and conservation activities may not retain public support. Approaches to mitigate human-sloth bear conflict should emphasize avoiding sloth bears when they are sighted and conducting activities near forests during the day and in groups when possible. Strategies such as improving sanitation facilities, developing effective compensation schemes, forming conflict management teams, and establishing sloth bear conservation awareness programs for villagers, as well as improving cooperation among various stakeholders, are necessary to foster human-sloth bear coexistence. © 2017 International Association for Bear Research and Management.

Wastes generated from fruits and vegetables are organic in nature and contribute a major share in soil and water pollution. Also, green house gas emission caused by fruit and vegetable wastes (FVWs) is a matter of serious environmental concern. This review addresses the developments over the last one decade on microbial processing technologies for production of enzymes and organic acids from FVWs. The advances in genetic engineering for improvement of microbial strains in order to enhance the production of the value added bio-products as well as the concept of zero-waste economy have been briefly discussed. © 2015 Elsevier Inc.

Climate change induced sea level rise (SLR) added with anthropogenically altered environment leads to rapid land dynamics in terms of erosion and accretion; and alteration in species diversity and productivity, more pronouncedly in sensitive ecosystems such as river deltas. Here, we tried to analyze the historical records to understand the SLR with respect to hydrological conditions, sedimentation and morphological processes. We analyzed the land transformation of few islands in Indian Sunderbans using maps and satellite images in increasing order of temporal frequency between 1924 and 2008, which revealed that both the erosion and accretion processes go hand in hand. Increase of downstream salinity due obstruction in upstream has led to decrease in transparency of water causing decrease in phytoplankton and fish, density and diversity in the central sector of Indian Sunderbans. Analysis of the above ground biomass of three dominant mangrove species (Sonneratia apetala, Avicennia alba and Excoecaria agallocha) revealed better growth in the western sector compared to the central sector. The study reveals the cumulative effect of climate change and anthropogenic disturbance on the diversity and productivity in World's largest ecosystem; and advocates mangrove plantation and effective management of freshwater resources for conservation of the most vulnerable and sensitive ecosystem. © 2012 Springer Science+Business Media B.V.

Nonlinear Dynamics | Year: 2015

In this paper, we study the complex dynamics of a spatial nonlinear predator-prey system under harvesting. A modified Leslie–Gower model with Holling type IV functional response and nonlinear harvesting of prey is considered. We perform a detailed stability and Hopf bifurcation analysis of the spatial model system and determine the direction of Hopf bifurcation and stability of the bifurcating periodic solutions. Numerical simulations were performed to figure out how Turing patterns evolve under nonlinear harvesting. Simulation study leads to a few interesting sequences of pattern formation, which may be relevant in real world situations. © 2014, Springer Science+Business Media Dordrecht.

The alterations in the salinity profile are an indirect, but potentially sensitive, indicator for detecting changes in precipitation, evaporation, river run-off, glacier retreat, and ice melt. These changes have a high impact on the growth of coastal plant species, such as mangroves. Here, we present estimates of the variability of salinity and the biomass of a stenoecious mangrove species (Heritiera fomes, commonly referred to as Sundari) in the aquatic subsystem of the lower Gangetic delta based on a dataset from 2004 to 2015. We highlight the impact of salinity alteration on the change in aboveground biomass of this endangered species that, due to different salinity profile in the western and central sectors of the lower Gangetic plain, shows an increase only in the former sector, where the salinity is dropping and low growth in the latter, where the salinity is increasing.

Present paper consists the record of six species of mudskippers along with their morphometric analysis and spatial distribution from Bhitarkanika mangroves of Odisha, in the east coast of India. The six species of mudskippers are distributed under six genera Apocryptes (A. bato), Baleopthalmus (B. boddarti), Parapocryptes (P. serperaster), Periophthalmus (P. novemradiatus), Pseudapocryptes (Ps. elongatus) and Scartelaos (S. histophorus). The study was conducted from November 2010 to March 2013 in Bhitarkanika Wildlife sanctuary covering four survey sites representing degraded mangrove in downstream seaward side, the mangrove region and degraded mangrove in upstream tidal riverward side. While Baleopthalmus boddarti and Pseudapocryptes elongatus are found in all four habitats, Parapocryptes serperaster and Scartelaos histophorus are found both from seaward side and riverward side. Apocryptes bato are exclusively from upstream tidal riverward side and Periopthalmus novemradiatus are found exclusively from mangrove regions. P. serperaster were found to be the longest, A. bato were the heaviest and P. novemradiatus were the smallest as well as lightest. © 2015, National Institute of Science Communication and Information Resources (NISCAIR).

Natural leaf senescence was investigated in four rainfed lowland rice cultivars, FR 13A (tolerant to submergence), Sabita and Sarala (adapted to medium depth, 0-50 cm stagnant flooding) and Dengi (conventional farmers' cultivar). Changes in the levels of pigment content, CO2 photosynthetic rate, photosystem II photochemistry and anti-oxidant enzyme activities of flag leaves during grain-filling stage were investigated. Chlorophyll content, photochemical efficiency of photosystem II and CO2 photosynthetic rate decreased significantly with the progress of grain-filling. Likely, the activities of antioxidant enzymes namely, superoxide dismutase, catalase, guaiacol peroxidase and ascorbate peroxidase decreased with progress of grain-filling. A substantial difference was observed among the four cultivars for the sustainability index (SI) of different photosynthetic parameters and antioxidant enzyme activities; SIs of those parameters, in general, were lower in low yielding cultivar FR 13A compared to the other three cultivars. Among the four cultivars Sabita gave maximum grain yield. Yet, SI of Pn was greater in Sarala and Dengi compared to the Sabita. SIs of electron transport (ETo/CS), maximal photochemical efficiency (Fv/Fm), area above Fo and Fm, catalase and ascorbate peroxidase were also greater in Sarala and Dengi. The data showed that among the different Chl a fluorescence parameters, PI could be used with greater accuracy to distinguish slow and fast senescence rice cultivars during grain-filling period. It was concluded that maintaining the vitality of rice plants during grain-filling gave guarantee to synthesize carbohydrate, however greater yield could be realized provided superior yield attributing parameters are present. © 2012 Prof. H.S.

For high rate multiplication of different medicinal plants, it is necessary to standardize the protocol for high regeneration. The efficiency of any regeneration is primarily depends on factors like type of explants used, composition of the medium and type of genotype. Here we have developed a regeneration protocol using in vitro grown seedling explants of Desmodium gangeticum (L.) DC (Salparni) a medicinal plant through somatic embryogenesis. Explants from in vitro grown seedlings were cultured on Murashige and Skoog's basal medium with BA at different concentrations for callus initiation. Different explants cultured on MS medium containing different concentrations of BA (0.1-1.0 mg L -1) produced friable non-embryogenic callus (brownish white) with many small, smooth, rounded, discreet and greenish unit of embryogenic callus within the first week of inoculation. For induction of somatic embryogenesis, these friable embryonic callus derived from cotyledon, hypocotyl, epicotyl and leaf explants were transferred to MS medium supplemented with various growth regulators like BA, Kn, 2,4-D, NAA, CH (casein hydrolysate) and BA with 3% glucose. Most of the somatic embryos derived from the induction medium germinated like normal embryos producing both tap root and shoot on regeneration medium and also greenish sprouted embryoids with only roots or shoots or secondary somatic embryos i.e., clusters of embryos or poly embryos are found. Only shoots measuring 3 cm or more derived from somatic embryos were excised and planted on semi solid basal medium supplemented with varying concentrations of IBA for induction of rooting. All the explants in the medium containing BA 0.5 mg L -1 responded high. In the higher concentration of BA all the explants produced non-regenerative hard callus. However, the cotyledon is best explants over all to produce plants through somatic embryogenesis. Somatic embryogenesis derived plantlets of D. gangeticum showed 77% of survival. The in vitro propagation protocol standardized can be highly useful in raising quality planting materials of Desmodium gangeticum for commercial plantation programmes. © 2012 Academic Journals Inc.

Every society or culture has its own belief, notion, attitude, knowledge, test and perception about drink and non-drink, superior drink and inferior drink etc., which are rooted in the framework of cultural logic of specific society or community. Positive, integrated, non-temperance cultures tend to favour more 'open' drinking environments, while negative, ambivalent, temperance cultures are associated with 'closed', insular designs. The health status of individuals and groups is influenced not only by environmental factors but also by a variety of personal attributes, including genetic heritage, psychological dispositions and behavioural patterns. The studied hill Bonda of Odisha is such a community that they use different types of alcoholic beverages as a food item and as a part of their cultural celebrations. This paper tries to focus on genetic, socio-cultural and ecological analysis of the protective aspect against alcoholism among the hill Bonda tribal group where in a health ecological context drinking alcoholic beverages is common for all from birth to death. © Serials Publications.

The aim of the present study was investigation the effects of fly ash and mining soil on growth and antioxidant protection of two cultivars of Indian wild rice (Oryza nivara and Oryza rufipogon) for possible phytoremediation and restoration of metal contaminated site. In this study, Indian wild rice showed significant changes in germination, growth and biochemical parameters after exposure to different ratio of fly ash and mining soil with garden soil. There was significant reduction of germination, fresh weight, dry weight, leaf chlorophyll content, leaf area, SPAD index, proteins, and activities of antioxidant enzymes in both cultivars of the wild rice grown in 100% fly ash and mining soil compared to the plants grown in 100% garden soil. Results from this study showed that in both cultivars of wild rice, all growth and antioxidant parameters were increased when grown in 50% fly ash and mining soil. Taken together, Indian wild rice has the capacity to tolerate 50% of fly ash and mining soil, and can be consider as good candidate for possible phytoremediation of contaminated soils.
