“…This suggests that the Mississippi River is a long‐standing, important biogeographic barrier that has promoted the origins and maintenance of biodiversity for extant taxa across the southeastern Nearctic. To better understand community‐wide patterns of dispersal, divergence, and gene flow in relation to changes in the hydrology of the Mississippi River (e.g., Cox et al, ), future comparative analyses should focus on both the number and timing of population divergence events and shared historical demography across entire assemblages of taxa (Myers et al, ; Xue & Hickerson, ).…”

“…No gene flow, despite suitable habitat on either side of the barrier, suggests that the Mississippi River has been an important feature of the landscape in promoting divergence, potentially via allopatry. Numerous studies have identified lineage formation across this barrier in taxonomic groups as varied as terrestrial (Brant & Ortí, ; Burbrink, Fontanella, Pyron, Guiher, & Jimenez, ; Burbrink et al, ; Leaché & Reeder, ; Myers et al, ) and aquatic vertebrates (Brandley, Guiher, Pyron, Winne, & Burbrink, ; Near, Page, & Mayden, ), plants (Al‐Rabab'ah & Williams, ; Zellmer, Hanes, Hird, & Carstens, ), and invertebrates (Katz, Taylor, & Davis, ; Satler & Carstens, ). The timing of lineage divergence across this important barrier is unknown for many taxa, however estimates from other studies range from the late Miocene (e.g., Lemmon, Lemmon, Collins, Lee‐Yaw, & Cannatella, ) to the Pleistocene (e.g., Howes, Lindsay, & Lougheed, ).…”

Biogeographic barriers, Pleistocene refugia, and climatic gradients in the southeastern Nearctic drive diversification in cornsnakes (Pantherophis guttatus complex)

The southeastern Nearctic is a biodiversity hotspot that is also rich in cryptic species. Numerous hypotheses (e.g., vicariance, local adaptation, and Pleistocene speciation in glacial refugia) have been tested in an attempt to explain diversification and the observed pattern of extant biodiversity. However, previous phylogeographic studies have both supported and refuted these hypotheses. Therefore, while data support one or more of these diversification hypotheses, it is likely that taxa are forming within this region in species‐specific ways. Here, we generate a genomic data set for the cornsnakes (Pantherophis guttatus complex), which are widespread across this region, spanning both biogeographic barriers and climatic gradients. We use phylogeographic model selection combined with hindcast ecological niche models to determine regions of habitat stability through time. This combined approach suggests that numerous drivers of population differentiation explain the current diversity of this group of snakes. The Mississippi River caused initial speciation in this species complex, with more recent divergence events linked to adaptations to ecological heterogeneity and allopatric Pleistocene refugia. Lastly, we discuss the taxonomy of this group and suggest there may be additional cryptic species in need of formal recognition.

Amphibians and reptiles of C. E. Miller Ranch and the Sierra Vieja, Chihuahuan Desert, Texas, USA

We report the occurrence of 50 species of amphibians and reptiles recently collected on C. E. Miller Ranch and the Sierra Vieja in the Chihuahuan Desert of Texas, USA and describe their perceived distribution and abundance across various habitat associations of the region. Our recent surveys follow intense, historic sampling of amphibians and reptiles from this region in 1948. Of the 50 species detected in recent surveys, six were not collected in 1948 and an additional three species documented in 1948 have yet to be detected in a 14-year period of recent surveys. Combining data from both historic and recent surveys, a total of 53 species of amphibians and reptiles are known from the ranch (11 amphibians, 42 reptiles). Land stewardship and conservation practices have likely contributed to the persistence of the majority of these species through time. Additionally, we discuss the status of amphibians and reptiles not collected during recent surveys and comment on potential species that have not yet been detected.

Geographical features are the predominant driver of molecular diversification in widely distributed North American whipsnakes

et al. 2017

View full text Add to dashboard Cite

Allopatric divergence following the formation of geographical features has been implicated as a major driver of evolutionary diversification. Widespread species complexes provide opportunities to examine allopatric divergence across varying degrees of isolation in both time and space. In North America, several geographical features may play such a role in diversification, including the Mississippi River, Pecos River, Rocky Mountains, Cochise Filter Barrier, Gulf of California and Isthmus of Tehuantepec. We used thousands of nuclear single nucleotide polymorphisms (SNPs) and mitochondrial DNA from several species of whipsnakes (genera Masticophis and Coluber) distributed across North and Central America to investigate the role that these geographical features have played on lineage divergence. We hypothesize that these features restrict gene flow and separate whipsnakes into diagnosable genomic clusters. We performed genomic clustering and phylogenetic reconstructions at the species and population levels using Bayesian and likelihood analyses and quantified migration levels across geographical features to assess the degree of genetic isolation due to allopatry. Our analyses suggest that (i) major genetic divisions are often consistent with isolation by geographical features, (ii) migration rates between clusters are asymmetrical across major geographical features, and (iii) areas that receive proportionally more migrants possess higher levels of genetic diversity. Collectively, our findings suggest that multiple features of the North American landscape contributed to allopatric divergence in this widely distributed snake group.
