    Study on avian frugivory and seed dispersal in the shoal forests of Nilgiri Hills, Western Ghats, India.
    (SACON, 2013) Anbarasu, C.; Balasubramanian, P.
    A study on avian frugivory and seed dispersal in 111'0 shola forests of Nilgiri hills, Western Ghats was carried out from January 2009 to July 20 I I. Longwood shola is situated between 11 °43.494'N and 0760 87A63'E) and Eppanadu shola between I lo29. IS]'N and 0760 47.223'E. The objectives or the present study were, i). study avian frugivory and find out major frugivores in the shola forests ii). assessing fruiting phenology of fleshy-fruited tree species and find out the fruiting seasonality, iii). establish the role of avian frugivores in seed dispersal and forest regeneration. Vegetation sampling was done in both the shola forests, Longwood and Eppanadu. One h3 plot (50x20m) were laid in e3ch of the above-mentioned two shola s. Data collected were analyzed to obtain quantitative structure and composition of plant communities. Fruiting periodicity was determined by monitoring tagged trees for 24 months.

    Habitat utilization by Malabar Grey Hornbill at Mudumalai Wildlife Sanctuary, Western Ghats. (TH12)
    (SACON, 2002) Maheswaran, B.; Balasubramanian, P.
    Utilization of habitat resources, particularly fruit and nest trees, by an endemic bird species, Malabar Grey Hornbill (Ocyceros griseus) was studied in a tropical semi-evergreen forest and the adjoining tea/coffee plantations at Mudumalai Wildlife Sanctuary, Western Ghats. This bird species is mainly distributed in the moist forests of southern Western Ghats. Though some aspects of Malabar Grey Hornbill in an evergreen forest at Anamalai Hills have been studied during the breeding season, fruit utilization during the non-breeding season is not known. Also, the preference of this endemic hornbill for food and nest tree species is unknown. This study aimed to assess the food preferences of Malabar Grey Hornbill during breeding and non-breeding seasons, nest-tree preferences and to identify the keystone resources for the Malabar Grey Hornbill in the semi-evergreen forest.
