  • Title
    Phylogenetic position and osteology of Pethia setnai (Chhapgar and Sane, 1992), an endemic barb (Teleostei: Cyprinidae) of the Western Ghats, India, with notes on its distribution and threats
    Type
    Journal Article
    Description
    Pethia setnai is an endemic and threatened freshwater fish of the Western Ghats of India. It has a restricted distribution in the west flowing rivers in the states of Maharashtra, Goa and Karnataka. We clarify the phylogenetic position of Pethia setnai, provide osteological details of topotypic material, and morphometric data of specimens from Maharashtra, Goa and Karnataka. We also provide details on micro-level distribution, habitat and threats to the species in its native range.

  • Title
    Ecology and conservation of threatened plants in Tapkeshwari Hill ranges in the Kachchh Island, Gujarat, India
    Type
    Journal Article
    Description
    The survey was conducted in Tapkeshwari Hill Range (THR) areas, wherever threatened plant species were said to exist, based on secondary information in literature. Thirteen plant species categorized as ‘Threatened’ by the World Conservation Monitoring centre (WCMC 1994) and also listed under various threat categories in the Red Data Book of Indian Plants (Nayar & Sastry 1988) were surveyed in the THR. All the RET plants reported from the study area occupied eight major habitat types. Thorn mixed forests harbored the highest number of individuals (560) of all RET plants, followed by open scrubs (345 individuals), Acacia senegal forests (328) and thorn mixed scrubs (293). Field observations showed that except Helichrysum cutchicum, all the other RET plant species were reported with very low seedlings and regeneration ratio. This paper discusses the status, distribution and threats faced and the conservation implications at border regions of some of the threatened plants of the arid Kachchh district.

  • Title
    CEPF Western Ghats Special Series: Reproductive biology of Puntius denisonii, an endemic and threatened aquarium fish of the Western Ghats and its implications for conservation
    Type
    Journal Article
    Description
    This study presents fundamental information on the reproductive biology of Puntius denisonii, an endemic and threatened aquarium fish of the Western Ghats Hotspot. Results are based on the observations from three river systems, Chandragiri, Valapattannam and Chaliyar. Maximum observed total length in P. denisonii was 162mm and 132mm for males and females, respectively. Males attained sexual maturity at a lower size than females with mean size at first maturity determined as 85.33 plus or minus 1.52 mm for males and 95.66 plus or minus 1.15 mm for females. Puntius denisonii spawned from October to March with minor differences in the peak breeding months between the three river systems, which were studied. Sex ratio deviated significantly from 1:1 and was skewed in favour of males. Absolute fecundity varied from 376 (fish of 102mm total length) to 1098 (fish of 106mm total length) eggs. Currently, the closed seasons for P. denisonii have been put in place during June, July and October based on the (mis)assumption that the species breeds during these three months. However, the results of the present study have helped us to understand more about the reproductive biology of the species so as to recommend more appropriate seasonal closures. The months from October until March need to be designated as a closed season for protecting the breeding population of P. denisonii.
