    Type
    Journal Article
    Description
    Field surveys across various parts of the country coupled with an analysis of literature and examination of herbarium specimens revealed the natural distribution of six wild relatives of crop species in various states/union territories of India, viz., Cajanus scarabaeoides (from Lakshadweep), Cucumis javanicus (from Meghalaya), Hystrix duthiei (from Jammu & Kashmir), Luffa echinata (from Haryana) and Trichosanthes pilosa (from Andhra Pradesh), which have not been reported earlier from these states.

    Butterfly fauna of Baghmundi, Purulia, West Bengal, India: a preliminary checklist
    Type
    Journal Article
    Description
    The butterfly diversity of Baghmundi, Purulia District (22.600–23.500N & 85.750–86.650E), West Bengal, India was studied from January 2014 to December 2015 with photographic documentation. A total of 54 butterfly species were recorded representing 39 genera in six families. Nymphalidae was the most dominant family with 46.3% of the total species. As this is the first report of butterfly diversity from this region, the present study may help in planning conservation strategies and generate awareness among the local people and government authorities to save wildlife and their habitats.

    Observations on the association of Scaphula deltae Blanford (Mollusca: Bivalvia) in Garanga Wetland of Pobitora Wildlife Sanctuary, Assam, India
    Type
    Journal Article
    Description
    During a survey of the Garanga wetland of Pobitora Wildlife Sanctuary, Scaphula deltae Blanford (Mollusca: Bivalvia) was recorded for the first time. Most examples were found over Lamellidens corrianus (Lea) in a firmly attested position. Some were also found clinging to the roots of Eichhornia crassipes. These findings establish a new record of freshwater mollusc association in the study area. Some of the physico-chemical parameters of the study area were also investigated.

  • Title
    A new species of sea squirt Rhopalaea bilobata (Ascidiacea: Diazonidae) from the Andaman Islands, India
    Type
    Journal Article
    Description
    Rhopalaea bilobata, a new species of the class Ascidiacea, under the family Diazonidae has been described from the Andaman Islands of Andaman & Nicobar, India. The species was found in sandy bottoms, reef areas and artificial structures at a depth range of 10–40 m. This species has bilobed anal border, six lobed branchial and atrial siphons, transparent thorax with pigmented spots at the anus, between the two siphons and at the anterior end of endostyle, and ramified basal test. The species is closely related to R. idoneta, R. macrothorax and R. tenuis in several sets of anatomical and morphological features.

  • Title
    Freshwater fish fauna of Hiranyakeshi River, the northern Western Ghats, India
    Type
    Journal Article
    Description
    The freshwater fish fauna of Hiranyakeshi River, a tributary of the Krishna River System, originating in the Western Ghats of Maharashtra, was studied for a period of three years from 2013–2016. We reported 57 species belonging to seven orders, 17 families and 42 genera. Cypriniformes was the most species rich order followed by Siluriformes, while Cyprinidae was the most predominant family. At least 21 freshwater fish species found in Hiranyakeshi River are endemic to river systems originating from the Western Ghats, while nine species are endemic to the Krishna River system. The true diversity of freshwater fishes in this region, however, is still obscure because of lack of detailed taxonomic studies in this region. Of the total species, at least 11 are in the threatened and near threatened categories of the IUCN Red List and Hiranyakeshi River holds a good population of most of these species. The fish fauna in this region, however, is threatened by several stressors including invasive fishing practices, water impediment due to upcoming dams, invasive introduced species and water pollution due to agricultural runoffs and industrial effluents.

  • Title
    On two little-known terrestrial South Asian geckoes Hemidactylus reticulatus and Hemidactylus scabriceps (Reptilia: Gekkonidae)
    Type
    Journal Article
    Description
    We studied two poorly known terrestrial geckoes inhabiting peninsular India namely, Hemidactylus reticulatus Beddome, 1870 and H. scabriceps (Annandale, 1906). We present data on their morphometry, scalation, colouration and field observations based on both studies in the field and on voucher specimens. Hemipenal morphology for H. scabriceps is presented herein for the first time. Seen in light of some recent cases of misidentification between these two ecologically-similar parapatric species, the present work aids in precise identification and presents landscape clues that help understand their ecology.

  • Title
    The sighting of Mandarin Duck Aix galericulata (Linnaeus) (Aves: Anseriformes: Anatidae) after a gap of 112 years in Assam, India
    Type
    Journal Article
    Description
    A female Mandarin Duck Aix galericulata was sighted in Saatvoini Beel on February 10, 2014. The female of this species was characterized by grey head, with a white ring around the eye which continued as a streak behind it. In India Mandarin Duck is vagrant and there were very few reported records from India. In 1902, Baker reported six individuals Mandarin Duck on the Subansiri River, Assam. The present sighting of this species from Baksa district is the first reliable record of this species in Assam after a gap of 112 years.

    Status and conservation of Eastern Hoolock Gibbon Hoolock leuconedys in Assam, India
    Type
    Journal Article
    Description
    A field survey was conducted in 2010 from March to May in the reserve forests of Sadiya sub-division, in the Tinsukia District of Assam, India, to investigate the status of the Hoolock Gibbon. The data were collected using modified line-transect and call-count methods. We recorded 10 groups of gibbons in three reserve forests, through direct sighting. Of the 33 individuals recorded through direct sighting 63.6% were adults, 21.2% juveniles and 15.2% infants. The average group size of the sighted groups was 3.3 individuals, with an adult sex ratio of 1:1.1. We also recorded 10 groups of Rhesus Macaques in the area. Anthropogenic pressures included encroachment, felling of trees and inadequate infrastructure, and these were the major threats for Hoolock Gibbon and other wildlife in the region. Notably, the gibbons of Sadiya have been identified as the Eastern Hoolock Gibbon Hoolock leuconedys and this is the first report of the species from Assam.
