National Autonomous University of Mexico (UNAM) Details Findings in Life Sciences [Genetic and Morphological Differentiation Among Populations of the Narrowly Endemic and Karst Forest-adapted pilea Pteridophylla (Urticaceae)]

Article Description

In this study, the influence of geographic isolation on the levels of morphological and genetic differentiation among populations of the karst forest-adapted Pilea pteridophylla (Urticaceae) was evaluated. Based on our results, there is a strong morphological differentiation among the only two know populations of Pilea pteridophylla. Both populations can be clearly differentiated based on vegetative and reproductive characters, and the observed variation is geographically structured. Moreover, our genetic data from the chloroplast genome show strong levels of population differentiation and no shared haplotypes were observed between populations. Also, our estimation of divergence times supports a long-term isolation hypothesis between populations. Based on our results, dispersal seed limitation, long-term forest isolation and topographic heterogeneity (local adaptation) are related to high levels of endemism and species turnover in the mountain karst forests of Mexico.
