  • Title
    A quantification of damage and assessment of economic loss due to crop raiding by Asian Elephant Elephas maximus (Mammalia: Proboscidea: Elephantidae): a case study of Manas National Park, Assam, India
    Type
    Journal Article
    Description
    A study was carried out in Manas National Park, Assam in northeastern India between 2007 and 2009 to understand the magnitude of human-elephant conflict through a quantification of damage and assessment of economic loss. A cluster of six villages adjacent to the Park was selected for this study. Five major agricultural crops were grown during the study period of which three were raided by elephants: winter paddy, autumn paddy and pulses. Paddy was the principle crop central to the farmers’ subsistence. Winter paddy was the most cultivated crop and autumn paddy was the least cultivated. The incidence rate of crop raiding was highest for autumn paddy and lowest for pulses. Overall economic loss due to crop raiding was negligible, however at the individual farmer level, it was quite high. The study revealed that human-elephant conflict is not so severe, indicating ample opportunity for human-elephant coexistence in the region. Crop fields adjacent to the Park were particularly vulnerable to crop raiding which necessitates creation of a buffer zone. The frequency of raiding and the extent of damage was found to be significantly less in crop fields which were guarded by farmers. This was due to traditional crop guarding practices being followed in the region, the strengthening of which could effectively reduce annual crop loss and thus human-elephant conflict could be minimized to a large extent.

  • Title
    The family Rubiaceae in southern Assam with special reference to endemic and rediscovered plant taxa
    Type
    Journal Article
    Description
    Analysis of diversity, distribution and endemism of the family Rubiaceae for southern Assam has been made. The analyses are based on field observations in the three districts, viz., Cachar, Hailakandi and Karimganj, as well as data from existing collections and literature. The present study records 90 taxa recorded from southern Assam, four of which are endemic. Chassalia curviflora (Wall.) Thwaites var. ellipsoides Hook. f. and Mussaenda keenanii Hook.f. are rediscovered after a gap of 140 years. Mussaenda corymbosa Roxb. is reported for the first time from northeastern India, while Chassalia staintonii (H.Hara) Deb and Mondal is reported as a new record for Assam.

  • Title
    Forest ghost moth fauna of northeastern India (Lepidoptera: Hepialidae: Endoclita, Palpifer, and Hepialiscus
    Type
    Journal Article
    Description
    Taxonomic and biological information is reviewed for the forest Hepialidae of northeastern India, a poorly known group of moths in a region known for the global significance of its biodiversity. The taxonomic and biological characteriscs are described for genera known from the northeast - Endoclita, Palpifer, and Hepialiscus. A key is provided for distinguishing these genera and the genus Thitarodes known from nearby Bhutan, China, and Nepal, which is almost certainly present within the borders of India. Taxonomic characteristics are described for 12 species from the northeast along with illustrations of the species and maps of their known distributions. Information on species distributions is extremely fragmentary and it is considered very likely that most species have more extensive distributions than currently documented. The northeastern Indian region represents a center of hepialid diversity comprising three principal distribu on patterns: (i) local endemics, (ii) Himalayan, and (iii) northeastern. Comparison of distribution records and major vegetation types indicate the absence of information on the hepialid fauna for much of the northeast region. The principal challenge for future documentation and assessment of the hepialid fauna for this region, as with any other part of India, is the lack of modern descriptions of type specimens. The inclusion of voucher collections of Hepialidae in future biodiversity surveys of northeastern India is to be strongly encouraged, particularly in the context of current and future environmental impacts affecting the sustainability of forest environments in the region.

  • Title
    The seasonal occurrence of the Whale Shark Rhincodon typus (Smith, 1828) (Orectolobiformes: Rhincodontidae) along the Odisha coast, India
    Type
    Journal Article
    Description
    This article gives a description about the seasonal occurrence of Whale Shark in the southern Odisha coast by taking into account of the current observed data and published literatures. The present report claims the sighting of whale sharks during offshore surveys on 13th March 2016 and 15th March 2016, 8 km (19° 15’ 38” N, 85° 01’32” E) and 4.5 km (19º 15’ 69” N, 85° 00’ 58” E) off the coast of Gopalpur Port, Odisha respectively. Most of the earlier reports of whale shark sightings along Odisha coast are from the coastal waters off Rushikulya river mouth or Gopalpur during the month of February-March. Continuous records of whale sharks along southern Odisha coast during February and March suggest the probability of seasonal migration of this giant fish during the period.

  • Title
    Density and obligatory feeding habits of an isolated Golden Jackal Canis aureus L. (Mammalia: Carnivora: Canidae) population in Pirotan Island, Gulf of Kachchh, India
    Type
    Journal Article
    Description
    Efforts to arrest the decline of carnivorous mammals in isolated ecosystems have received little attention in India. The present study assesses the population density of a small Golden Jackal population, isolated on a water covered Pirotan Island in the Gulf of Kachchh Marine National Park, India. An average of 12 Golden Jackals/km2 was found inhabiting the Island. The scat analysis revealed that the major diet of jackals was crab (89.5±2.36 %) followed by fish (2.7±0.82 %). Only 2.1% of their diets were from the Island source. They have well adapted to manage their water needs from their obligatory feeding habits.

  • Title
    Host specificity of some wood-decaying fungi in moist deciduous forests of Kerala, India
    Type
    Journal Article
    Description
    The low diversity tropical forest is dominated by host specialized wood decaying fungi (Hymenochaetales, Polyporales) with narrow host range. To understand whether or not wood decaying fungi in a highly diverse tropical moist deciduous forest have any kind of host specialization, sporophores of 22 species of wood decaying fungi were recorded on 17 tree species in three seasons viz., pre monsoon, monsoon and post monsoon from the moist deciduous forests of Peechi-Vazhani Wildlife Sanctuary, Kerala, India. Only two of the 22 species with three or more records showed signs of host specialization. In the case of other fungi, the number of host tree species increased with increasing number of occupied or colonized logs. The findings support the assumption that most of the wood decaying fungi have broad host ranges in highly diverse forest types in the tropics.

    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.
