| sequence-based molecular phylogenetics and phylogeography of the american box turtles (terrapene spp.) with support from dna barcoding. | the classification of the american box turtles (terrapene spp.) has remained enigmatic to systematists. previous comprehensive phylogenetic studies focused primarily on morphology. the goal of this study was to re-assess the classification of terrapene spp. by obtaining dna sequence data from a broad geographic range and from all four recognized species and 11 subspecies within the genus. tissue samples were obtained for all taxa except for terrapene nelsoni klauberi. dna was extracted, and the ... | 2013 | 23523575 |
| contrasting demographic and genetic estimates of dispersal in the endangered coahuilan box turtle: a contemporary approach to conservation. | the evolutionary viability of an endangered species depends upon gene flow among subpopulations and the degree of habitat patch connectivity. contrasting population connectivity over ecological and evolutionary timescales may provide novel insight into what maintains genetic diversity within threatened species. we employed this integrative approach to evaluating dispersal in the critically endangered coahuilan box turtle (terrapene coahuila) that inhabits isolated wetlands in the desert-spring e ... | 2008 | 19378401 |
