| Abstract | In this study, we analysed patterns of intraspecific structuring between populations of Leptobrachium hendricksonifrom southern Thailand using qualitative and quantitative morphological characters. Furthermore, we compared the phenotypicdivergence with neutral genetic variation based on the concatenated mtDNA 12S, 16S and ND4 sequences (2,452bp). Nonparametric ANOVA analyses in combination with Monte Carlo simulations and Chi-square test for qualitative characters,showed differences in phenotypical variation between populations of L. hendricksoni from southern Thailand. UPGMAclustering based on size-and-shape variation and size variation, and simulations under scenario where each population wasrepresented by 100 individuals (structuring in consensus tree p = 0.5), yielded a similar pattern of population distribution. Ourresults highlight the role of ecological mechanisms of adaptation to local habitat types and climate conditions as a driving forceaffecting the distribution of morphological characters within L. hendricksoni rather than genetic differentiation due to randomdrift and/or genetic flow. |
