    Diversity and distribution of Moth Assemblages Along Altitudinal Gradient in Gangotri Landscape, India
    (Wildlife Institute of India, Dehradun, 2015) Sanyal, Abesh Kumar; Uniyal, V.P.
    This study intends to document the extent of moth assemblages that exist amongst various habitats in a typical Western Himalayan altitudinal gradient in Gangotri Landscape Area (GLA). In this study, using the elevation gradient as natural experiment, the faunal structure and diversity of the moth assemblage featuring all the major macro and micromoth families as well as relationships between moths and their biotic and abiotic environments were explored. Specific objectives of the study were: (1) Documenting and prepare taxonomic inventory of rich moth fauna of Gangotri Landscape Area; (2) To assess diversity and distribution of moth assemblages among different elevations and vegetation types of Gangotri Landscape; (3) To analyze the influence of altitude, seasons, vegetation types and anthropogenic disturbance factors on moth assemblages; (4) To investigate morphometric changes (body size and proportional body parts) in moths along altitudinal gradient. The study was conducted in Gangotri Landscape Area (GLA), a vast conservation network in the North-Western part of Uttarakhand, in district Uttarkashi. A total of 670 morphospecies belonging to 22 families and 356 genera were collected during entire sampling period from 2008-2012. This study is an important step towards better understanding of a long-neglected but diverse and charismatic herbivorous insect assemblage in Himalayan temperate altitudinal gradient.

    Diversity of spider assemblages in sacred groves of Ratnagiri, Maharashtra: Implications for conservation management in the landscape.
    (Wildlife Institute of India, Dehradun, 2016) Patil, Vinayak K.; Uniyal, V.P.; Trivedi, Mukul
    The present study was conducted in Dapoli Taluka of Ratnagiri district in maharashtra with the objectives was to comprehensively document the sacred groves in the study area because it is a high concentration sacred groves region but very little documentation has been done so far. The other objective was to explore the spider diversity in sacred groves and compare it with some other habitats in the study area. These habitats included, reserved forests, mango orchards and cashew orchards. Lastly it was sought to find out if the habitats, seasonality, disturbance etc. had any influence on the diversity and composition of spider assemblages in the study sites.
