Impact of Altitudes on Soil Characteristics in Dry Deciduous Forest Ecosystem, Western Ghats, Tamil Nadu

The present investigation was carried out in a dry deciduous forest of Maruthamalai hills to know the changes in species composition according to altitude and ecology of economically important plants. A total number of 128 plant species were identified and 112 of them are recognized as economically important.Based on importance value index, the species like Acacia torta, Chloris barbata, Eragrostis viscosa, Erythroxylon monogynum Pterolobium indicum and Zizyphus oenoplia are ecologically well established plants in the study forest. On the other hand the spices such as Polygala Jacobi, Portulaca guadrifida, Ruellia patula,Sida rhomboidea, Waltheria indica, Calotropis gigantean, Solanum torvum, Acacia leucophloea, Acacia nilotica, Acacia trotitis, Agave Americana, Bambusa arundinacea, Cassia fistula, Chloroxylon swietenia, Peltophorum pterocarpum, Pithecellobium dulce, Pongamia pinnata, Prosopis juliflora, Samanea saman,Thespesia populnea, Canavalia mollis, Leptadenia reticulata, Rivea hypocrateriformis etc., are considered as ecologically weaker species in the community. Hence priorities must be given to these species so as to protect the genetic stock and species as well.

A New Species

A new genus of enigmatic tribe Physocrotaphini, Physoglossus gen. nov., with a new species Ph. devagiriensis sp. nov. from a dry deciduous forest in the rain shadow belt of the south Western Ghats in south west India is described. Presence of mentum with bifid median tooth and large oval depression with dense patch of filamentous setae on 2nd and 3rd male sternites makes it intermediate to the Physocrotaphini genera, Pogonoglossus, Foveocrotaphus and Physocrotaphus. Key words: new ground beetle species, Anthiinae, the Western Ghats, India

Streblus Asper

This paper describes the fruiting phenology and avian frugivory of Streblus asper (Moraceae) in a mixed dry deciduous forest, Anaikatty hills, Western Ghats. Fruiting occurred during April-June. Nine species of birds were found to feed on the ripe fruits of this species. Bulbuls (3 species) belonging to Pycnonotidae, followed by two species of Myna (Sturnidae) made majority of the feeding visits and appear to be the major seed dispersers of this species
