“…A series of mid-peninsular seaways have been postulated as isolating barriers to account for these phylogeographic splits, even though geological evidence supporting existence of seaways had been largely absent. In this case, the comparative phylogeographic signal motivated geologists to investigate the plausibility of mid-peninsular seaways, concluding that regional geology is consistent with Miocene but not Plio-Pleistocene seaways (51).…”

Deciphering the geographic context of diversification and distributional dynamics in continental biotas has long been an interest of biogeographers, ecologists, and evolutionary biologists. Thirty years ago, the approach now known as comparative phylogeography was introduced in a landmark study of a continental biota. Here, I use a set of 455 studies to explore the current scope of continental comparative phylogeography, including geographic, conceptual, temporal, ecological, and genomic attributes. Geographically, studies are more frequent in the northern hemisphere, but the south is catching up. Most studies focus on a Quaternary timeframe, but the Neogene is well represented. As such, explanations for geographic structure and history include geological and climatic events in Earth history, and responses include vicariance, dispersal, and range contraction-expansion into and out of refugia. Focal taxa are biased toward terrestrial or semiterrestrial vertebrates, although plants and invertebrates are well represented in some regions. The use of various kinds of nuclear DNA markers is increasing, as are multiple locus studies, but use of organelle DNA is not decreasing. Species distribution models are not yet widely incorporated into studies. In the future, continental comparative phylogeographers will continue to contribute to erosion of the simple vicariance vs. dispersal paradigm, including exposure of the widespread nature of temporal pseudocongruence and its implications for models of diversification; provide new templates for addressing a variety of ecological and evolutionary traits; and develop closer working relationships with earth scientists and biologists in a variety of disciplines.biogeography | biodiversity conservation | evolutionary biology | diversification | ecology

“…Baja California has been the focus of many phylogenetic and phylogeographic studies due to its unique geologic history and high endemism (Dolby, Bennett, Lira-Noriega, Wilder, & Mungu ıa-Vega, 2015;Grismer, 2002;Lindell, M endez-De La Cruz, & Murphy, 2008;Riddle, Hafner, Alexander, & Jaeger, 2000;Savage, 1960;Zink, 2002). Many of the taxa that have been examined have shown spatially concordant phylogenetic or phylogeographic breaks at one, two or three key regions in Baja California: the mid-peninsula, near the town of Loreto and at the Isthmus of La Paz (Figure 1; Riddle, Hafner, Alexander, & Jaeger, 2000).…”

“…Given the timing of divergence and contact, we suggest that climatic fluctuations have driven the observed phylogeographic structure observed in C. ruber and that they may have driven similar patterns in other taxa.

No strong evidence has been presented to suggest that a seaway crossed the peninsula in the vicinity of Loreto, leaving the drivers of spatially concordant phylogenetic and phylogeographic breaks unclear at all of these regions.…”

Aim: Many studies have investigated the phylogeographic history of species on the Baja California Peninsula, and they often show one or more genetic breaks that are spatially concordant among many taxa. These phylogeographic breaks are commonly attributed to vicariance as a result of geological or climatic changes, followed by secondary contact when barriers are no longer present. We use restriction-site associated DNA sequence data and a phylogeographic model selection approach to explicitly test the secondary contact hypothesis in the red diamond rattlesnake, Crotalus ruber.Location: Baja California and Southern California. Methods:We used phylogenetic and population clustering approaches to identify population structure. We then used coalescent methods to simultaneously estimate population parameters and test the fit of phylogeographic models to the data. We used ecological niche models to infer suitable habitat for C. ruber at the Last Glacial Maximum (LGM).Results: Crotalus ruber is composed of distinct northern and southern populations with a boundary near the town of Loreto in Baja California Sur. A model of isolation followed by secondary contact provides the best fit to the data, with both divergence and contact occurring in the Pleistocene. We also identify a genomic signature of northern range expansion in the northern population, consistent with LGM niche models showing that the northern-most portion of the range of C. ruber was not suitable habitat during the LGM. Main conclusions:We provide the first explicitly model-based test of the secondary contact model in Baja California and show that populations of C. ruber were isolated before coming back into contact near Loreto, a region that shows phylogeographic breaks for other taxa. Given the timing of divergence and contact, we suggest that climatic fluctuations have driven the observed phylogeographic structure observed in C. ruber and that they may have driven similar patterns in other taxa. Grismer, 2002;Lindell, M endez-De La Cruz, & Murphy, 2008;Riddle, Hafner, Alexander, & Jaeger, 2000;Savage, 1960;Zink, 2002) (Aguirre, Morafka, & Murphy, 1999;Murphy, 1983).However, this hypothesis has been weakened by a general lack of direct geological evidence and the finding that mid-peninsular divergences indicate at least two episodes of divergence (Crews & Hedin, 2006;Dolby et al., 2015;Leach e, Crews, & Hickerson, 2007). No strong evidence has been presented to suggest that a seaway crossed the peninsula in the vicinity of Loreto, leaving the drivers of spatially concordant phylogenetic and phylogeographic breaks unclear at all of these regions.The phylogeographic patterns observed could be produced by at least two different processes: (1) Here, we sought to examine the phylogeography of mainland populations of Crotalus ruber (the red diamond rattlesnake), a large rattlesnake that ranges throughout Baja California and into southern California (Figure 1), using genomic data and explicit testing of alternative phylogeographic models. We also inv...

“…These biogeographic barriers include marine incursions into the Salton Trough associated with the opening of the Gulf of California (ca. 6.3 Ma, Oskin and Stock 2003, Dolby et al 2015), and the more recent drainage of the Colorado River into the Gulf (ca. 4.1 Ma, Dorsey et al 2007, Dolby et al 2015).…”

New species in the Sitalcina sura species group (Opiliones, Laniatores, Phalangodidae), with evidence for a biogeographic link between California desert canyons and Arizona sky islands

The western United States is home to numerous narrowly endemic harvestman taxa (Arachnida, Opiliones), including members of the genus Sitalcina Banks, 1911. Sitalcina is comprised of three species groups, including the monospecific Sitalcina californica and Sitalcina lobata groups, and the Sitalcina sura group with eight described species. All species in the Sitalcina sura group have very small geographic distributions, with group members distributed like disjunct “beads on a string” from Monterey south to southern California and southeast to the sky-island mountain ranges of southern Arizona. Here, molecular phylogenetic and species delimitation analyses were conducted for all described species in the Sitalcina sura group, plus several newly discovered populations. Species trees were reconstructed using multispecies coalescent methods implemented in *BEAST, and species delimitation was accomplished using Bayes Factor Delimitation (BFD). Based on quantitative species delimitation results supported by consideration of morphological characters, two new species (Sitalcina oasiensis sp. n., Sitalcina ubicki sp. n.) are described. We also provide a description of the previously unknown male of Sitalcina borregoensis Briggs, 1968. Molecular phylogenetic evidence strongly supports distinctive desert versus coastal clades, with desert canyon taxa from southern California more closely related to Arizona taxa than to geographically proximate California coastal taxa. We hypothesize that southern ancestry and plate tectonics have played a role in the diversification history of this animal lineage, similar to sclerophyllous plant taxa of the Madro-Tertiary Geoflora. Molecular clock analyses for the Sitalcina sura group are generally consistent with these hypotheses. We also propose that additional Sitalcina species await discovery in the desert canyons of southern California and northern Baja, and the mountains of northwestern mainland Mexico.
