  • Title
    CEPF Western Ghats Special Series : Diversity and distribution of anurans in Phansad Wildlife Sanctuary (PWS), northern Western Ghats of India
    Type
    Journal Article
    Description
    In global consequences of rapidly changing climate and increased amphibian population decline, mapping amphibian diversity in biodiversity hotspots is essential. In this study we have systematically studied anurans of Phansad Wildlife Sanctuary in terms of species diversity, population structure, threat status and distribution. We recorded a total of 22 anuran species, of which 11 species are endemic to Western Ghats biodiversity hotspot. Family Dicroglossidae was found to be more species-rich. Spatial and temporal variation in anuran diversity was observed by using Shannon diversity and evenness indices. Most of the endemic and threatened anuran species are found to be associated with evergreen undisturbed forest patches. Habitat parameters like humidity, forest type, canopy coverage, riparian canopy coverage, stream persistence and litter depth are found to be major variables governing species diversity and distribution. Major anthropogenic threats to amphibians of Phansad Wildlife Sanctuary are discussed along with future conservation objectives. With range extension of species like Fejervarya caperata and Minervarya sahyadris further north in the Western Ghats, taxonomic ambiguities recorded during study are discussed briefly.

  • Title
    An overview of fish fauna of Raigad District, northern Western Ghats, India
    Type
    Journal Article
    Description
    We studied the fish fauna of Raigad District for two years from August 2008 to August 2010. Sixty six freshwater and secondary freshwater fish species belonging to 31 families and 53 genera were collected from various sampling sites and local markets along the banks of Patalganga, Bhogawati, Amba, Kundalika, Mandad and Savitri river systems present in Raigad District, Maharashtra, northern Western Ghats. Cyprinids were the most dominant group represented by 22 fish species belonging to 13 genera followed by the loaches, croakers and gobies belonging to the family Balitoridae, Sciaenidae and Gobiidae respectively (three species from each family). Of the 66 fish species, five belong to the Vulnerable (VU), four to Near Threatened (NT), 37 to the Least Concern (LC) category and 20 were found to be not evaluated for IUCN Red List criteria. Raigad District is under severe threat of rapid industrialization and urbanization. Further, introduced exotic fish species are becoming a major threat to the indigenous fish fauna of Raigad District. Implementation of ecosystem based adaptation plans and conservation measures are necessary to protect the diverse, endemic and threatened fish fauna of Raigad District.
