  • Title
    An inventory of mammals, birds and reptiles along a section of the river and banks of upper Ganges, India
    Type
    Journal Article
    Description
    A study was conducted to assess faunal diversity along a 165-km stretch of the upper Ganges River between Bijnor and Narora cities, Uttar Pradesh, from January to June 2007. Both river and bank species diversity of reptiles, birds and mammals using a combination of boat surveys, linear walks and random searches were inventoried. Presence of 18 species of mammals, 55 species of birds and 13 species of reptiles were recorded from the river stretch including 16 species of global conservation significance. Maximum encounter rate was observed for little cormorant (3.160 plus or minus 0.290), macaque (2.385 plus or minus 0.442) and brown roofed turtle (1.009 plus or minus 0.107). Our study is an attempt towards generating baseline information on the faunal diversity of the upper Ganges and we recommend exhaustive surveys and regular monitoring of this river stretch through indicator species approach.

  • Title
    Rapid assessment of Wreathed Hornbill Aceros undulates (Aves: Bucerotidae) populations and conservation issues in fragmented lowland tropical forests of Arunachal Pradesh, India
    Type
    Journal Article
    Description
    A rapid assessment of Wreathed Hornbills, their distribution and abundance was carried out in fragmented lowland tropical forests of Lower Dibang Valley District, Arunachal Pradesh, northeastern India from October 2010 to April 2011 using the total count method. A total of 62km distance was covered on foot to survey four study sites: Horupahar, Delo, Koronu and Injunu. Nine flocks of 172 hornbills were sighted. Aceros undulatus flock size ranged from 8-38 individuals with a mean of about 19.1 plus or minus 2.6. Illegal logging, hunting for bushmeat and other body parts (feathers, beak etc.) for decorating the head gear and house interiors by the local tribals were observed as the major threats to the species in the study areas.

  • Title
    Road kills of amphibians in different land use areas from Sharavathi river basin, central Western Ghats, India
    Type
    Journal Article
    Description
    A survey of amphibian mortality on roads was carried out in the Sharavathi river basin in the central Western Ghats. Road kills in three different land use areas: agricultural fields, water bodies and forests were recorded for four days along three 100m stretches in each type of area. One-hundred-and-forty-four individuals belonging to two orders, eight families, 11 genera and 13 species were recorded in the survey. Kills/km observed were: in forest 55, agricultural fields 38 and water bodies 27, for an overall average of 40 kills/km. Kill species compositions varied significantly between land use areas, but not overall kill rates.
