  • Title
    Conservation status assessment and new population record of the threatened Golden Himalayan Spike Phlomoides superba (Royle ex Benth.) Kamelin & Makhm. from Jammu & Kashmir, India
    Type
    Journal Article
    Description
    This paper deals with distribution and conservation status of the Golden Himalayan Spike Phlomoides superba (Royle ex Benth.) Kamelin & Makhm. (syn. Eremostachys superba Royle ex Benth.), an endangered herb in India. A new locality report from Jammu & Kashmir along with population status in previously reported localities of occurrence of this species is also provided. Since the species is reported from a very few localities in India and is facing critical threats in the wild, the addition of a new locality holds significance in terms of its declining population status.

  • Title
    An update on the distribution pattern and endemicity of three lesser-known tree species in the Western Ghats, India
    Type
    Journal Article
    Description
    The present communication reports an update on the distribution of three endemic tree species of the Western Ghats-Sri Lanka biodiversity hotspot, namely, Atuna indica (Bedd.) Kosterm., Paracroton integrifolius (Airy Shaw) N.P.Balakr. & Chakrab. and Phaeanthus malabaricus Bedd. The discovery of these taxa in the Makutta Ghat of Kodagu District results in the extension of their northern range limits and further enriches the flora of Karnataka state by three more tree species. Within the Western Ghats, these taxa were previously recorded only from the states of Kerala and Tamil Nadu, while Paracroton integrifolius (Airy Shaw) N.P.Balakr. & Chakrab. has also been recorded from Sri Lanka. Nomenclature updates, detailed descriptions, conservation status and relevant notes on the habitat, phenology and distribution localization are supplied. Additionally, field photographs and scanned herbarium specimens are provided to facilitate easy identification of these taxa in the field.

  • Title
    Distribution records and extended range of the Sri Lanka Frogmouth Batrachostomus moniliger (Aves: Caprimulgiformes: Podargidae) in the Western Ghats: a review from 1862 to 2015
    Type
    Journal Article
    Description
    The Sri Lanka Frogmouth (or Ceylon Frogmouth) Batrachostomus moniliger is an endemic resident bird confined to the evergreen and secondary forests of Sri Lanka and the Western Ghats of India. The earlier distribution range of the Frogmouth was from the Uttara Kannada District of Karnataka to the southern tip of India and most of Sri Lanka. Recently, the range has been extended further north to Goa and up to Mumbai in Maharashtra. A number of observations summarized into 202 distributional records (published reports and records uploaded to eBird basic data set, Oriental Bird Images, and GBIF.org from the years 1862 to 2015) of the Frogmouth have been tabulated with its maps, and reviewed for their state-wise distribution records. The need of undertaking surveys to fill up the gaps in their distribution range as well as any further northward extension till the culmination of the Western Ghats has been discussed. It is urged that taxonomical and molecular phylogenetic studies are required to be carried out in different populations of Frogmouths across the entire range.

    Gentiana saginoides Burkill (Magnoliopsida: Gentianales: Gentianaceae) rediscovered from Sunderdhunga Valley in Uttarakhand 155 years after description: notes on its population status
    Type
    Journal Article
    Description
    Gentiana saginoides Burkill (Gentianaceae) was described by Burkill in 1906 based on a collection from Sunderdhunga, Uttarakhand by T. Anderson in 1857. The species was not collected after its type collection despite attempts by several workers in the past. A field survey in and around the type locality was conducted in June 2012 and the species was re-discovered after a lapse of 155 years since its type collection. The species is tentatively categorised as ‘Critically Endangered’ based on field observations. A full description and diagrams of the species are provided here based on new specimens collected.

  • Title
    Distribution, habitat utilisation and conservation status of the freshwater crab, Somanniathelphusa zanklon Ng & Dudgeon, 1992 (Crustacea: Brachyura: Gecarcinucidae) endemic to Hong Kong
    Type
    Journal Article
    Description
    Somanniathelphusa zanklon Ng & Dudgeon, 1992 is a tropical freshwater crab currently considered endemic to Hong Kong.  The present study shows that S. zanklon has been found in a variety of lotic and lentic habitats, mostly lowland, slow moving streams and marshes.  The species is more widely distributed than previously known, and potentially occurs outside Hong Kong.  However, its habitat is under threat from development and channelization of watercourses.  The life cycle of the crab requires both slow moving streams and marshes for adults and adjacent terrestrial habitats for brooding females, highlighting the need for integrated conservation of lowland streams and their riparian corridors.  It is hoped that understanding of the species habitat requirements will encourage others to further explore lowland watercourses in the Pearl River Delta and aid in habitat conservation.

  • Title
    The seasonality of butterflies in a semi-evergreen forest: Gibbon Wildlife Sanctuary, Assam, northeastern India
    Type
    Journal Article
    Description
    A study spanning 3.7 years on the butterflies of Gibbon Wildlife Sanctuary GWS (21km2), a semi-evergreen forest, in Jorhat District of Assam, northeastern India revealed 211 species of butterflies belonging to 115 genera including 19 papilionids and seven ‘rare’ and ‘very rare’ species as per Evans list of the Indian sub-continent (Great Blue Mime Papilio paradoxa telearchus; Brown Forest BobScobura woolletti; Snowy Angle Darpa pteria dealbatahas; Constable Dichorragia nesimachus; Grey Baron Euthalia anosia anosia; Sylhet Oakblue Arhopala silhetensis; Branded Yamfly Yasoda tripunctata). The butterflies showed a strong seasonality pattern in this forest with only one significant peak during the post monsoon (September-October) when 118 species were in flight inside the forest which slowly declined to 92 species in November-December. Another peak (102 species) was visible after winter from March to April. Species composition showed least similarity between pre-monsoon (March-May) and post-monsoon (October-November) seasons. The number of papilionid species were greater from July to December as compared from January to June. The findings of this study suggest that the pattern of seasonality in a semi-evergreen forest in northeastern India is distinct from that of the sub-tropical lowland forest in the Himalaya. Favourable logistics and rich diversity in GWS points to its rich potential in promoting ‘butterfly inclusive ecotourism’ in this remnant forest.

  • Title
    Range extension of two poorly known endemic species of the genus Orophea Blume (Annonaceae)
    Type
    Journal Article
    Description
    Orophea malabarica Sasidh. & Sivar. and Orophea sivarajanii Sasidh., of the family Annonaceae were found growing in close proximity as undergrowth with restricted distribution in the evergreen forest of Makutta Ghat, Kodagu District, Karnataka State, India.  Earlier reports suggest that these are endemic to Kerala state of the Western Ghats and found distributed only in their type localities viz., Thrissur and Wayanad districts respectively. However, the present article reports extension of their range to new locations in Karnataka state and therefore become addition to the floral wealth of the state, as they were neither previously collected nor recorded from this region. The updated nomenclature, detailed description, flowering-fruiting seasons, distribution map, scanned herbarium specimens, field photographs, proposed conservation status and other relevant notes are provided in this communication.
