Resumen

The Muslims of Darjeeling Himalaya an a mosaic of diverse ethnic groups. They are divided into a number of segments and social groupings, and a notion of hierarchy or social gradation on the basis of purity is observed among them; though theoretically, Islam advocates an egalitarian social order. The present paper helps us to dispel an established monolithic believe regarding the social and cultural homogeneity of the Indian Muslims, and come to prove the differences in their religious ideologies, cultural practices, and ethnic characters. The covert (i.e., Islamic ideology based on textual Islam), and overt, (i.e., local traditions or lived Islam) aspects of the society have also been examined, as an existing phenomena, as the Muslim society of Darjeeling Himalayan town is deeply fragmented into various social orders. An effort has been made here to sketch an account of the social stratification of the Himalayan Muslims through an extensive field work in the Himalayan town of Darjeeling, West Bengal.

Chettri A, Sharma K, Dewan S, Acharya BK. 2018. Bird diversity of tea plantations in Darjeeling Hills, Eastern Himalaya,India. Biodiversitas 19: 1066-1073. The biodiversity wealth and conservation potential of agro-ecosystems including cash cropplantations is gaining significance in recent years. Agro-forestry provides ecosystem services similar to forest and, hence, support a highdiversity of flora and fauna. This study was undertaken to explore the bird community in different tea gardens of Kurseong Hill,Darjeeling, Eastern Himalaya, India. Darjeeling is globally known for its extent and magnificent tea production. We sampled birds usingpoint count methods along transects during August 2015-January 2016. A total of 581 individual birds comprising 48 species wererecorded during the study. Amongst the guild types, insectivorous birds were the most dominant both in terms of species andabundances. Depending on their habitat preferences most of the birds were forest generalists followed by forest specialists. This studyhighlights that tea plantations have a great potential in harbouring and conserving birds and other associated life forms. Thus, propermanagement of these landscapes would be an effective strategy to conserve biodiversity of the Himalayas.

Resumen

Abstract The article presents the role of the newly built reservoir in the formation of the hydrochemistry of water of the Teesta River (a tributary of the Brahmaputra) in its Himalayan course. Field research were performed in the post-monsoon season of the period 2013-2015. Sampling and measuring points were located in five points over 43 km of the Teesta River in the Darjeeling Himalaya. Analysis of water along of river longitudinal profile above and below the reservoir suggest that the reservoir caused decrease most of the basic ions concentrations (Cl−, K+, Na+, Mg2+, NO3− and PO43−). An inverse trend was observed only with respect to Ca2+, SO42− and NH4+. The dam does not influent on the F− concentration. The reservoir causes minor enrichment most of the heavy metals such Cu, Ni, Zn, Cr, Cd and Sr. The lower enrichment of Teesta water below the dam indicates the water self-purification processes for metals by the Teesta Reservoir. The changes of physicochemical properties and concentrations of ions caused by the reservoir are usually normalised by environmental factors before the Teesta River outlet from the Himalayas (within 15 km of the river).

Resumen

Abstract. A first ever study on the characterization of volatile organic compounds (VOCs) has been made over a Himalayan high altitude station in India. A total of 18 VOCs (mono aromatics-BTEX (benzene, toluene, ethylbenzene, xylene), non-BTEX substituted aromatics and halocarbon) have been measured over Darjeeling (27.01° N, 88.15° E, 2200 m a.s.l.) in the eastern Himalaya in India during the period of July 2011–June 2012. The annual average concentration of the sum of 18 target VOCs (TVOC) was 376.3 ± 857.2 μg m−3. Monoaromatics had the highest contribution (72%) followed by other substituted aromatics (22%) and halocarbon (6%) compounds. Toluene was the most abundant VOC in the atmosphere of Darjeeling with the contribution of ~37% to TVOC followed by benzene (~21%), ethylbenzene (~9%) and xylenes (~6%). TVOC concentrations were highest during the postmonsoon season with minimum solar radiation and lowest during the premonsoon season with maximum solar radiation. Anthropogenic activities related mainly to tourists like diesel and gasoline emissions, biomass and coal burning, use of solvent and solid waste emissions were almost equal in both the seasons. Seasonal variation in TVOCs over Darjeeling was mainly governed by the incoming solar radiation rather than the emission sources. Source apportionment study using Positive Matrix Factorization (PMF) model indicated that major fraction of (~60%) TVOC were contributed by diesel and gasoline exhausts followed by solvent evaporation (18%) and other sources. Diesel exhaust was also found to have the maximum potential in tropospheric ozone formation. The atmospheric loading of BTEX over Darjeeling was found to be comparable with several Indian metro cities and much higher than other cities around the world.

Resumen

Pollen analysis of Late Holocene lacustrine sediments from Jore-Pokhari, a temperate lake of eastern Himalaya, has revealed that around 2500 yr B.P. mixed broad-leaved Oak forests existed, reflecting to a warm-temperate and humid climate in the region. Between 1600- and 1000-year B.P. a short-term cool-oscillation is witnessed as evidenced by decline in broad-leaved tree taxa and a simultaneous increase in the conifers. The anthropogenic activities have also been noticed during this period as evidenced by the increase in grasses together with culture pollen such as Chenopodiaceae/Amaranthaceae, Caryophyllaceae, Artemisia and Asteraceae as well as appearance of Cerealia type pollen. Between 1000- and 300-year B.P. the improvement in the broad-leaved taxa, viz., Quercus, Betula and Alnus and reappearance of Rhododenrdron as well as simultaneous decline in Pinus indicate the amelioration of climate which became warm-temperate the humid once again.

Resumen

Abstract Water scarcity in mountain regions such as the Himalaya has been studied with a pre-existing notion of scarcity justified by decades of communities' suffering from physical water shortages combined by difficulties of access. The Eastern Himalayan Region (EHR) of India receives significantly high amounts of annual precipitation. Studies have nonetheless shown that this region faces a strange dissonance: an acute water scarcity in a supposedly ‘water-rich’ region. The main objective of this paper is to decipher various drivers of water scarcity by locating the contemporary history of water institutions within the development trajectory of the Darjeeling region, particularly Darjeeling Municipal Town in West Bengal, India. A key feature of the region's urban water governance that defines the water scarcity narrative is the multiplicity of water institutions and the intertwining of formal and informal institutions at various scales. These factors affect the availability of and basic access to domestic water by communities in various ways resulting in the creation of a preferred water bundle consisting of informal water markets over and above traditional sourcing from springs and the formal water supply from the town municipality.

Resumen

The Lepchas, an ethnic group indigenous to the Himalayas and the Darjeeling hills, have been weaving textiles from local nettle (Girardinia diversifolia) for millennia. However, their native land, centered around the former Kingdom of Sikkim in modern-day northeastern India, has been the site of centuries of cultural exchange and colonization despite its remoteness, entailing wide-ranging and continuous social, political, and economic changes within the area. Rapid regional industrialization, and the concomitant globalization process and urbanization will potentially further transform Lepcha culture. Despite this, the Lepchas continue to weave textiles they consider traditional. With that in mind, this article will consider the concept of ‘tradition’ and its place in post-industrial Sikkim, using these textiles as a basis for understanding the significance of ‘tradition’ and how ‘tradition’ is used as a tool for carving a place out in the contemporary world. This study analyzes its deployment in contemporary Lepcha textiles so as to illuminate the relationship between tradition, textiles, and contemporary Lepcha identity.

Resumen

Landslide susceptibility map aids decision makers and planners for the prevention and mitigation of landslide hazard. This study presents a methodology for the generation of landslide susceptibility mapping using remote sensing data and Geographic Information System technique for the part of the Darjeeling district, Eastern Himalaya, in India. Topographic, earthquake, and remote sensing data and published geology, soil, and rainfall maps were collected and processed using Geographic Information System. Landslide influencing factors in the study area are drainage, lineament, slope, rainfall, earthquake, lithology, land use/land cover, fault, valley, soil, relief, and aspect. These factors were evaluated for the generation of thematic data layers. Numerical weight and rating for each factor was assigned using the overlay analysis method for the generation of landslide susceptibility map in the Geographic Information System environment. The resulting landslide susceptibility zonation map demarcated the study area into four different susceptibility classes: very high, high, moderate, and low. Particle Swarm Optimization-Support Vector Machine technique was used for the prediction and classification of landslide susceptibility classes, and Genetic Programming method was used to generate models and to predict landslide susceptibility classes in conjunction with Geographic Information System output, respectively. Genetic Programming and Particle Swarm Optimization-Support Vector Machine have performed well with respect to overall prediction accuracy and validated the landslide susceptibility model generated in the Geographic Information System environment. The efficiency of the landslide susceptibility zonation map was also confirmed by correlating the landslide frequency between different susceptible classes.

Resumen

As many as 40 plant species belonging to 36 genera of 27 families were composing the study area - Gaddikhana Forest, Darjeeling. Among them 37 were dicotyledons and 3 monocotyledons. Its plant community was analyzed quantitatively and synthetically. The effective quadrate size was 90×90cm2. Diversity indices of 34 plant species and their evenness were determined. The proportional abundance of every species against its rank of abundance was also determined to deduce the allocation of individuals to species in communities. But for the population pressures the anthropogenic activities in forest regions are increased and in future it seems to be a major threat of biodiversity of Darjeeling.

Resumen

The study was concerned with an examination of antioxidant and antimicrobial activities of methanolic extract of Marchantia convoluta (Merch.) L.. collected from Darjeeling Himalaya. The antioxidant activities were evaluated by means of five in vitro methods, viz. free radical-scavenging activity, Fe3+ -reducing power, metal-chelating ability, trolox equivalent antioxidant capacity (TEAC) and activity in hydroxyl radical-scavenging system. The total phenol content was 1.1 mg gallic acid equivalents g-1 dried thallus. After 30 min of reaction, the 100 mg lyophilized extract possessed 6.7 % free radical-scavenging activity. The same amount of extract exhibited 13.4 % 168.2 % metal-chelating and hydroxyl radical scavenging activities, respectively. The reducing activity was found to be 28.5 mg ascorbic acid equivalents g-1 dried thallus. Total antioxidant activity was 0.18 μg TEAC g-1 dried thallus. The antimicrobial activity was evaluated by testing the methanolic extract of the samples against five microorganisms including two Gram positive bacteria (Staphylococcus aureus and Bacillus cereus), two Gram negative bacteria (Escherichia coli and Klebsiella pneumoniae) and one yeast (Candida albicans by disc-diffusion assay. M. convoluta thallus extract was more or less inhibitory against all of the test bacteria, however did not possess any antifungal property. S. aureus was found to be most sensitive target organism.

Resumen

Phytosociological investigation using 20 x 20 m quadrats has been made on seven major forest types of Darjiling foothill region within an altitudinal range of 135 m to 1200 m leading to the record of 215 species of trees, 11 species of liana and three species of palms. Analysis of data revealed that the East Himalayan Sal forest showed highest species diversity but have moderate species richness and concentration of dominance. High species diversity and species richness were recorded from Semi Evergreen Mixed forest, Wet Mixed Deciduous Forest & Lower Bhabar Sal Forest with correspondingly low concentration of dominance. Bamboo brake had the lowest species diversity with high concentration of dominance. Computation of similarity index showed a poor relation between different forest types and reflected the developing nature of vegetation. Also, these forests have a high regeneration status with a good species composition. It has also been predicted that the anthropogenic interferences may cause the abrupt change in the structure of these vegetation types.

Resumen

The study was concerned with an examination of antioxidant and antimicrobial activities of methanolic extract of Marchantia convoluta (Merch.) L.. collected from Darjeeling Himalaya. The antioxidant activities were evaluated by means of five in vitro methods, viz. free radical-scavenging activity, Fe3+ -reducing power, metal-chelating ability, trolox equivalent antioxidant capacity (TEAC) and activity in hydroxyl radical-scavenging system. The total phenol content was 1.1 mg gallic acid equivalents g-1 dried thallus. After 30 min of reaction, the 100 mg lyophilized extract possessed 6.7 % free radical-scavenging activity. The same amount of extract exhibited 13.4 % 168.2 % metal-chelating and hydroxyl radical scavenging activities, respectively. The reducing activity was found to be 28.5 mg ascorbic acid equivalents g-1 dried thallus. Total antioxidant activity was 0.18 μg TEAC g-1 dried thallus.

Resumen

The underground edible rhizomes and tubers are commonly known as "Taruls' in Darjeeling Himalaya and are mostly available during winter season. These vegetables are consumed as raw or processed through boiling for making them more palatable by local people of Darjeeling Himalaya. The methanolic extracts of raw and boiled (ten minutes) taruls were screened for their in vitro antioxidant potential by DPPH and ABTS' free-radicals, reducing power, metal chelating. nitric oxide, superoxide, hydroxyl radical scavenging capacity and anti-lipid peroxidation assays along with measuring in vitro antidiabetic activity by a-glucosidase and a-amylase inhibition. Our present study demonstrated that in majority of experimental assays, the performance of Dioscorea alata (ghar tarul) was best followed by Ipomoea batatas (red and white cultivar of sakarkanda) and D. hamiltonii (ban tarul), which showed stronger free-radical scavenging activity, high degree of different polyphenol content as well as antidiabetic capacity except for the iron-induced metal chelation where Sechium edule (squash-jara) was excellent performer. Therefore it can be stated that the extracts of different taruls might help in preventing or slowing the progress of various oxidative stress induced diseases. Our study also showed that in every antioxidant assays the scavenging activity reduced with boiling. As boiling decreases bioactive potency, it can be suggested that some alternative strategies should be developed during post-processing through which valuable phytochemicals of taruls might be preserved.

Resumen

Herpetospermum darjeelingense (C.B.Clarke) H. Schaef. & S.S. Renner is a rare cucurbit found in Darjeeling, Himalaya. It is known for its use as food and medicine with possible pharmaceutical applications. Here we assess the current and future habitat suitability of H. darjeelingense in the study area using MaxEnt modeling. In order to obtain accurate results for future models, the ensemble method was used. The current suitable habitat covers only 13% of the study area, while the future models for 2050 and 2070 show zero habitat suitability for the species. This strongly indicates a possible local extinction of the species indicating a need for rapid and decisive conservation efforts.

Resumen

This study attempts to assess the role of basin morphometric parameters in slope instability using a morphometric diversity (MD) model, as well as the role of drainage parameters and relief parameters in slope failure using drainage diversity (DD) and relief diversity (RD) models, respectively. For this, a total of 14 morphometric data layers were considered. The relationship of each data layer to landslide susceptibility was judged using a frequency ratio (FR) approach. Parameters like drainage density (Dd), drainage frequency (Df), relative relief (Rr), drainage texture (Dt), junction frequency (Jf), infiltration number (In), ruggedness index (Ri), dissection index (Di), elevation (E), slope (S), relief ratio (Rra) and hypsometric integral (Hi) were positively related with landslide potentiality while bifurcation ratio (Rb) and drainage intensity (Din) negatively correlated with S failure. The principal component analysis (PCA)-based weight assigned to each data layer in each model was multiplied with unidirectional reclassified data layers for each model using a weighted linear combination (WLC) approach to prepare landslide susceptibility maps. The receiver operating characteristics curve showed that the landslide prediction accuracy of the DD, RD and MD models were 71.4%, 73.9% and 76.3%, respectively. The FR plots of the aforesaid three models suggested that the chance of landslide increases from very low to very high in susceptible zones.

Resumen

Frec radicals are implicated for many chronic, painful and near-fatal diseases including Diabetes mellitus, arthritis, cancer, apoptosis, neurodegenerative disorders etc. In treatment of these discases, antioxidant therapy has gained an utmost importance and current rescarch is now directed towards finding naturaly occurring antioxidants of plant origin. Edible Timburs namely Zanthoxylum acanthopodium DC. and Litsea cubeba (Loureiro) Persoon are traditionally usced as spices in different Nepali recipes. In the present study, the fruits of these plants were extracted with aqucous methanol (1:4) to examinc the in vitro antioxidant property, phenol content and phytochemical constituents. The scavenging activities on DPPH free radicals, superoxide anions and per-oxidized lipid molecules were determined as well as the flavonoid and phenolic constitucnts of the extracts. The extracts exhibited significant scavenging activity towards DPPH free radicals and high anti-lipid peroxidation values duc to the presence of relatively high total phenol contents. Also, these spices contain a vast array of different phytochemicals in their dry form. These results suggest that both Zanthoxylum acanthopodium and Litsea cubeba fruits are endowed with antioxidant phytochemicals and could serve as basal ingredients for nutraceutical formulations.

Resumen

The Genus Phlogophora Treitschke, 1825 (Noctuidae: Xyleninae), widely distributed in Palaearctic and Oriental realms, is especially diverse within Indian Himalaya with 12 known species till now. Current communication reports three species new to India viz. P. meticulodina (Draudt, 1950), P. nobilis Hreblay & Ronkay, 1998 and P. szecsenyii Hreblay & Ronkay, 1998 and a new species P. similis Bandyopadhyay, Mallick, Sanyal & Chandra sp. nov., thus bringing the species number to 16 for the country, along with taxonomic key with morphology and genitalia-based diagnosis for all the Indian/Himalayan species. Out of those species, partial mitochondrial Cytochrome C Oxidase I (COI) sequences were generated for 6 species, of which 5 were novel to the NCBI GenBank. The genus had maximum species richness and abundance in Eastern Himalayan Temperate Forest spanning 1800–2500 m in Central Himalayan landscape of Darjeeling-Sikkim and Nepal. Current Habitat suitability model of six Phlogophora species indicated that temperature dependent variables like Temperature Annual Range, Temperature Seasonality and Elevation are the most contributing factors for their predicted distribution range. The genus comprising of both Polycyclic and Monocyclic species became most abundant during Post-monsoon, in cold (9–11 ºC) and humid (87–91%) nights, in areas with Annual Mean Temperature ranging within 4.6–19.9 ºC and Annual Precipitation of 1000–2800 mm.

Resumen

The availability of information on the distribution and occurrence of different species in a landscape is crucial to developing an informed conservation and management plan, however such information in the Himalaya is often limited. Citizen science, which builds on the knowledge and interest of communities to contribute to science, can be a solution to this problem. In this study, we used butterflies as a model taxon in the Darjeeling-Sikkim Himalaya which shows how citizen science can aid in documenting biodiversity. The study employed both citizen science, and researcher-survey approaches to collect data, and the collective effort resulted in 407 species, which is the highest by any study carried out in the region. Results show that citizen science can be helpful as a supplementary tool for data collection in biodiversity documentation projects, and can aid in adding to the diversity and distribution records of species, including those that are unique, rare, seasonal, and nationally protected. Citizen science outreach was used to muster potential participants from the local community to participate in the study. Thus, it is advisable for citizen science projects to find means to recruit a larger pool of contributors, and citizen science outreach can be key to their success.

Resumen

The Gish and Lish rivers are flowing through Higher Himalaya, Lesser Himalaya, Sub Himalaya and Quaternary Alluvium of the Sikkim- Darjeeling region. These thrust bounded tectonostratigraphic zones are comprised of different lithologies. Comparative sedimentological studies of the sediments of these rivers were undertaken to understand landforms developed by these rivers and source to sink relationships of these sediments. The Gish River fans are broad and wider as compared to the narrow and linear shaped fans of the Lish River. Textural analysis of these fan sediments revealed high energy conditions of deposition within these rivers. The petrographic analysis of the Gish River sediments shows dominance of Quartz (Qt63%F4% L33%) in the framework components, while the Lithic metamorphic fragments (Lm62% LV0% Ls 38%) show dominance over Lithic sedimentary fragments. This is also supplemented by the dominance of Quartz Polycrystalline grains (Qp62% Lv0% Ls38%) over Lithic sedimentary fractions. The Lish river sediments show dominance of Lithic fragments (Qt39% F2% L59%) in the framework components, while the Lithic sedimentary fragments (Lm44% Lv0% Ls56%) show dominance over lithic metamorphic fragments. This is also supplemented by Lithic sedimentary fractions (Qp41% Lv0% Ls59%) dominance over the Quartz Polycrystalline grains. These results of Quartz dominance in the Gish River sediments indicate higher contribution is from gneissic and metamorphic sources. While, Lithic dominance in the Lish River sediments infers higher contribution from sedimentary and metamorphic sources.
