Keywords: Acacia farnesiana, alien species, human footprint, potential distribution.
Abstract: The invasion of alien species in their non-native range has resulted in inevitable consequences. Thus, the potential distribution of alien species must be delineated to anticipate and reduce their negative effect on native ecosystems. The potential distribution can be predicted using invasive species distribution models human influence on the distribution of alien species when modeling their potential distribution. In the present study, we predict the potential distribution of Acacia farnesiana in the Himalayan hotspot using a popular iSDM. The effect of human influence was studied by comparing the potential distribution predicted using only bioclimatic variables and that using both bioclimatic and human footprint variables. We found that using both bioclimatic and human footprint variables, the potential distribution of target species could be 55.38 % larger than that of using only bioclimatic variables. This proves the positive effect of human activities on distribution of invasive species. Among the six considered bioclimatic variables, the mean temperature of the coldest quarter, the precipitation of the coldest quarter, and temperature seasonality are the most influential factors in determining the potential distribution of A.Farnesiana.

Keywords: Flash floods, landslide hazard zonation, satellite data, thematic layers.
Abstract: The Mandakini Valley of Rudraprayag district, Uttarakhand witnessed unprecented damage to life, property, infrastructure and landscape on 16 and 17 June 2013 due to torrential rains. Run-off discharge data indicate that antecedent rainfall exceeded the limit and the overflow of rivers led to landslide in the region and flash floods in the downstream areas. Fragile geology of the area, close to Main Central Thrust (MCT), degradation processes and torrential rains are responsible for triggering landslides and flash floods. A landslide inventory was carried out in the affected areas based on pre-and post-flood high resolution satellite data (LISS-IV) and Cartosat-2). A total of 290 landslides were identified from pre-flood satellite LISS IV (2011) imagery and 1665 were identified in post-flood satellite imagery along major rivers. Using remote sensing and geographic information system techniques, thematic layers were generated. Using the weightage rating system, a landslide hazard zonation map of the area was prepared. Each class within a thematic layer was assigned an ordinal rating from 1 to 9. Summation of these attribute values was then multiplied by the corresponding weights to yield different zones of landslide hazard. A landslide hazard zonation map having five different zones ranging very low hazard zone to very high hazard zone was prepared with the objective to create a reliable data-base for post-disaster management and for planning developmental activities in the district.

Keywords: Desert area, landscape entropy, marginal entropy, oozing of water.
Abstract: Oozing of groundwater in Jodhpur city in the desert area of Rajasthan, India has caused weakening of foundations and cellars of buildings and shops. It has become more significant since 1996 when Kaylana lake was connected with Rajiv Gandhi Lift Canal (RGLC) water supply and filling of the lake had started. This has resulted in fear among dwellers about any future calamity. The hydrogeological, hydrochemical and isotopic studies clearly indicated that the lake water is responsible for the oozing phenomenon in the area. This article highlights a landscape entropy approach to assess pathways causing rise in the level of groundwater integrating the measured lake water level and groundwater table in a few selected wells in the city. With the fractional information of lake water and groundwater, marginal entropies of lake water and depths to groundwater, is also provided. Subsequently, ratios of mutual information to marginal entropy of the lake water are used as a measure for demarcating the pathways of weak zones, which correlate well with the lineaments delineated from satellite imagery. The results of this study represent a base for additional insight on future work, which will help in tracing the connectivity of weak zones causing oozing of water in Jodhpur city, and evolving a plan for remedial measures.

Abstract: Rice is the major staple food crop for more than half of the world ' s population, but its productivity is often reduced by drought, especially when grown under rainfed conditions. Identification of molecular markers associated with plant production traits under drought, especially in the target populations of the environment (TPE) presents an opportunity to improve rainfed rice production using genomics tools. Marker-trait associations were studied using 1168 simple sequence repeat (SSR) markers and 911, 153 single nucleotide polymorphisms (SNPs) with 17 diverse rice lines from different geographical regions and hydrological habitats. STRUCTURE analysis discriminated the rice an accession into three subpopulations.Significant genotypic linkage disequilibrium (LD) was found in the rice accessions using SSR markers. A total of 130 and 118 water-trait associations were obtained with SSR and SNP markers respectively, under stress. Comparison of SSR and SNP marker-trait associations revealed 23 consistent associations. Five marker-trait associations with genic SNPs were observed out of 23 associations. These geonomic regions may be potential candidates for application in marker-assisted breeding of rice cultivars suitable for water-limited environments.

Keywords: Camptothecine, endophytic fungi, fungal diversity and distribution, Nothapodytes nimmoniana
Abstract: Nothapodytes nimmoniana Graham (Icacinaceae) is a small tree distributed along a 1600 km mountain range in the Western Ghats biodiversity hotspot in southern India. The stem wood of N.nimmoniana accumulates high concentration (about 0.3% by dry weight) of the anti-cancer alkaloid, camptothecine (CPT).Several endophytic fungi isolated from this plant have been shown to produce camptothecine in vitro.In this study, we examined the diversity and distribution of fungal endophytes of N.nimmoniana along its entire distributional range in the Western Ghats and investigated if the CPT-producing endophytes are restricted to any specific clade. The leaf and stem of N.nimmoniana were sampled from 18 sites along the Western Ghats spanning 8-18?N lat. Endophytes were recovered from all sites with the colonization frequency ranging from 0% to 52 % across the sites. One hundred and four endophytic fungal isolates were recovered from 118 plants and characterized both morphologically and by sequencing the internally transcribed spacer region of the nuclear rDNA gene. The fungal isolates belonged to 45 species (44 Ascomycetes and one Basidiomycetes).Fusarium and Hypoxylon were the most predominant genera comprising over half of the total isolates. Interestingly, CPT-producing endophytes were not restricted to any specific clade. We discuss these results in the context of the growing interest in endophytic fungi as possible alternatives sources of plant secondary metabolites.

Abstract: The importance of phyllosphere fungi to ecosystem functioning via soil processes has aroused increasing interest during the last decade. Here, we briefly review the current knowledge of how the foliar endophytic fungi and nutrient cycling interact. Recent findings suggest that control litter decomposition and the availability of nutrients in plant communities. However, the results obtained so far are highly variable. We attempt to integrate these observations with the knowledge of ecology and life-history strategies of endophytic fungi, and highlight general rules and gaps in our knowledge. Finally, we suggest testable hypotheses for future studies.

Keywords: Biomass deconstruction, marine-derived fungi, Trichoderma harzianum, xylan-degrading enzymes.
Abstract: Marine-derived fungi surviving as symptomless endophytes in seaweeds and seagrasses were screened for production of xylan-degrading enzymes. Of the eight endophyte isolates obtained from five different sea-grasses and another eight from six different marine algae, half of them exhibited xylanase activity in an agar plate assay. Further examination of these lead candidates using spectrophotometric assays revealed that Trichoderma harzianum, endophytic in the brown alga Sargassum wightii, had the maximum secreted xylanase and xylosidase activity, Moreover, this fungus could grow in NaCl-containing media (up to 1.2 M NaCl), and inclusion of 0.26 M NaCl in the media elicited in a two-and three-fold increase in extracellular xylanase and xylosidase activity respectively. These findings highlight the potential of prospecting marine-derived fungal endophytes to identify novel cell-wall degrading enzymes of value to the biofuel industry.

Abstract: Orchidaceae is one of the largest flowering plant families of the plant kingdom. The habitats of orchids are highly diverse, ranging from tree bark and damp forest floors to rock crevices, sandy dunes and semi-arid deserts. The diversity of endophytes (internal symbiotic fungi) associated with orchids is enormous. Most studies of endophytic fungi from orchids in the past have focused on mycorrhizal endophytes from orchids because of their physiological roles and their potential as sources of novel bioactive compounds. The review discusses the methods used in the isolation and identification of endophytic fungi from orchids, their diversity and host-specificity, their significance in orchid conservation and cultivation, and their potential application in the discovery of bioactive compounds.

Abstract: We studied assemblages of endophytic fungi on the halophilic plant salicornia europaea in Japan. This plant is disjunctively distributed in the eastern Hokkaido and the Seto Inland Sea (Setouchi) regions. Various dematiaceous fungi that form dark spores and/or mycelia (and the related ascigerous stages) were common in S.europaea. Among them, pleospora sp.(anamorph:Stemphylium) and Alternaria alternate were the major endophytes found in the plant, followed by Alternaria phragmospora and Cladosporium cladosporiodes.Fungal assemblages from Hokkaido were similar among years, as were assemblages collected in completely segregated regions in Japan, Hokkaido and Setouchi. While such dematiaceous fungi are generally known to be epiphytes living on the surface of terrestrial vascular plants, they may ubiquitously inhabit halophytes such as Salicornia.
