My doctoral research work, Resource utilization patterns of Reptiles in the Tropical Dry Mixed Deciduous Forests of Anaikatty Hills, Western Ghats, India, now published as a book. Ecological & taxonomic information’s on Reptiles of Tropical Dry forests of South-East Asia are scanty. Hence, its significance; which may further facilitate future research herpetologists to understand Reptile ecology in tropics. Alpha taxonomic description of a Colubrid species and a newly erected Gekkonid taxon is also included. Now the time to reanalyze ecology & taxonomy with biogeography, how Vicariance & Geo-dispersal allowed various Squamate reptiles (Sauria, Amphisbaenian & Ophidia) to evolve & adapt in different ecosystems on earth. Why some taxa are widely distributed, while others are not, Parallel, Convergent & Mosaic evolution. All these began with the continental drifting of land masses, dispersal & simultaneous species evolution. This may further give a better answer for today’s unstable taxonomic status of many taxa, speciation & rate of species extinction.
