The age of DHP and how pupfish colonized Devils Hole have always been a topic of interest. Recently, two different publications (Martin, Crawford, Turner, & Simons, & Sağlam et al., ) tackled this issue using genomic data sets and demographic models but came to widely different conclusions. In their comment, Martin and Höhne ( ) argue that our results (Sağlam et al., ) were misleading because we used inappropriate calibration...

The Devils Hole pupfish ( Cyprinodon diabolis ; DHP ) is an icon of conservation biology. Isolated in a 50 m 2 pool (Devils Hole), DHP is one of the rarest vertebrate species known and an evolutionary anomaly, having survived in complete isolation for thousands of years. However, recent findings suggest DHP might be younger than commonly thought, potentially introduced to Devils Hole by humans in the past thousand years. As a...

Species ranges that span different geographic landscapes frequently contain cryptic species‐ or population‐level structure. Identifying these possible diversification factors can often be accomplished under a comparative phylogeographic framework. However, comparisons suffer if previous studies are limited to a particular group or habitat type. In California, a complex landscape has led to several phylogeographic breaks, prima...

A species' genetic structure often varies in response to ecological and landscape processes that differ throughout the species' geographic range, yet landscape genetics studies are rarely spatially replicated. The C ope's giant salamander ( D icamptodon copei ) is a neotenic, dispersal‐limited amphibian with a restricted geographic range in the P acific northwestern USA . We investigated which landscape factors affect D . cope...
