Abstract: Advances in molecular and computational biology as well as in population genetics theory open new avenues in the study of speciation, for example enabling the explicit estimation of the amount of gene flow that has occurred during population divergence. Developments in two areas seem particularly important. First, novel coalescent-based methods can be applied to multilocus sequence data to infer the time of population divergence, long-term effective population sizes and their changes and the extent of gene flow between diverging populations. Second, the advent of ultra high-throughput sequencing technologies enable the inexpensive generation of vast amount of sequence data for any organism. Many amphibian species have been shown to be incompletely reproductively isolated and can hybridize for prolonged periods of time, making them ideal models to study the divergence of populations to form new taxa despite ongoing gene flow. Here I discuss the new findings emerging from multilocus DNA sequence-based approaches that have already been applied in amphibian population genetics. I also outline future directions of research, emphasizing the utility of parallel sequencing technologies together with methods of population genetic and phylogenetic inference, which are likely to provide a better understanding of the process of population differentiation and divergence to ultimately form new species.

IMPORTANT NOTE - JUNE 2020

Please note that as from Volume 31 Number 1 (January 2021) on, the Herpetological Journal will be available as an online publication only - the last print edition will be Volume 30 Number 4.   

Aligning with this change, it is now no longer possible to purchase a subscription that includes a print copy of the HJ.  All members who have existing HJ print subscriptions that remain active as at end June 2020 will receive the full four 2020 print editions.  New subscribers or renewals after this time will only have option to subscribe to the online only subscription package.  Subscription pricing has been amended to reflect the content changes.
