Studies on stigma-surface esterases in four RET Impatiens of Western Ghats

Abstract :

Dispersal patterns of harvester termite Anacanthotermes viarum (Konig) was analysed using RAPD of DNA sequences obtained from eleven populations from southern Tamil Nadu, South India. Two dispersal patterns viz., the Vaigai tract with the populations from Varushanadu, Chitalangudi, Madurai, Valayankulam, Paramakudi and Ramanathapuram and the dry tract of Southern Tamil Nadu with the populations of Vijayanarayanam, Nainarpuram, Kalligudi, Kovilpatti and Andipatti) could be discerned from genetic similarities. The termites from Varushanadu were unique and seemed to have moved from Southern tract and Vaigai tract. This movement of harvester termites from other parts to Varushanadu might be due to the impact of climatic conditions
