    Type
    Journal Article
    Description
    Salim Ali’s Fruit Bat Latidens salimalii is an IUCN Red listed Endangered species known only from a few locations in southern India. Here we report three records of Latidens salimalii from the Valparai plateau and Anamalai Tiger Reserve in Tamil Nadu where this species has not been previously recorded. This bat was caught in riparian habitats close to or inside intact tropical wet forest in the Western Ghats.

  • Title
    Effect of vehicular traffic on wild animals in Sigur Plateau, Tamil Nadu, India
    Type
    Journal Article
    Description
    The construction of a road, directly and indirectly, impacts on the ecosystems where the road is built. Highways passing through national reserves/wildlife sanctuaries have an adverse impact on wild animals. The present survey was conducted to estimate the road kills on the state highways passing through the Nilgiri north territorial forest division (19km) and Mudumalai Tiger Reserve (15km) in Sigur Plateau, Tamil Nadu, India. The road kills were monitored three times a month between July 2013 and December 2013 (six months) and a total of 176 road kills belonging to 30 species were recorded. Reptiles were the most affected taxa (39%), followed by mammals (33%) and birds (21%). Amphibians were least affected by vehicular traffic and comprised 7% of the total kills. According to road stretch category, the overall road kill was N=135 in the forested area and N=41 in human habitations. A total of 812 food materials were encounterd 612km with average of 1.32 food materials / km. Conservation and management implications are essential to prevent the local extinction of wildlife.

  • Title
    Morphology and taxonomy of Oscillatoria princeps Vaucher ex gomont (OSCILLATORIALES, OSCILLATORIACEAE)
    Type
    Journal Article
    Description
    Background:Oscillatoria princepshas been reported from various parts of India for its diversity but not studied in detail about morphology and reproduction hence we try to fill that lacuna. Methods:Samples were collected from a stream near Kanyakumari district, Tamil Nadu. One part was preserved in 4% formalin, while the other part was brought to unialgal culture by streaking method. The cultures were grown and maintained in ASN III (-NaCl) medium at the photoperiodic culture racks with 8 hours light and 16 hours dark. Semi-permanent slides were prepared and Leica EC3 Microsystems was used for observation and documentation. Findings:The alga was dark blue green in colour, growing in clusters at the bottom of the stream. Individual filaments were blue green to olive green in colour. Mature trichome straight, cells much broader than long with distinct cross walls. Apical cells hemispherical with keritomized content. Individual cells were round in shape and the size varies from 57.60μm to 69.05μm in width and 5.20μm to 9.55μm in length thus the ratio of length and breadth as 1:8. When such cells were stacked one above the other it gives "stack of poker chips" appearance, characteristic feature of the species. Notches were found at the inner side of the cell corresponding to the slit on the trichome. When such cells were stacked one above the other, it results in the crack like appearance on the trichome. One to three notches/slits were observed in the present study. Reproduction both by fragmentation and hormogonia (formation of separation disc) was observed. Application/Improvements:The new finding like cracks/ slit like structure on trichome can be taken for further studies. The microphotographs will enable the researchers to have better understanding. Keywords Cyanobacteria,Oscillatoria princeps, Kanyakumari, BGA, Hormogonia and Necridia.
