Trade and collection of edible frogs are banned in India. We used mitochondrial (16 and 12S DNA) and nuclear gene (Rag-1 and Rhodopsin) sequences to examine the population genetic and demographic structure of an edible frog species, (Karaavali Skittering frog) from Kerala as it exist after the ban. Frogs from 11 sites show high mtDNA haplotype and nDNA diversity which indicates a stable or expanding population. The evolutionary demographic pattern suggests population expansion across its geographical range, even though the species is still subject to poaching. Two major population clusters were observed at the northern and southern end of the species range. Gene flow occurs despite of geographic barriers. Genetic distance increases with geographical distance. . diverged from its sister species in around 11 mya in the late Miocene.
印度禁止食用青蛙的交易和捕捉。我们利用线粒体（16和12S DNA）和核基因（Rag-1和视紫红质）序列，研究了一种食用青蛙物种（卡拉瓦利窜蛙）在禁令实施后的种群遗传和人口结构，该物种来自喀拉拉邦。来自11个地点的青蛙显示出高线粒体DNA单倍型和核DNA多样性，这表明种群稳定或在扩张。进化人口模式表明，尽管该物种仍面临偷猎，但在其地理范围内种群仍在扩张。在该物种分布范围的北端和南端观察到两个主要的种群集群。尽管存在地理障碍，但基因流动仍在发生。遗传距离随地理距离增加。该物种在中新世晚期约1100万年前与其姐妹物种分化。
