It is clear that Pleistocene climatic cycles influenced species distributions and diversity around the world (Hewitt, 1996), yet questions remain regarding how these climatic fluctuations affected organisms inhabiting in the Nearctic arid regions. It has been suggested that during the cooling of the glacial periods, arid-adapted organisms were restricted to refugia in the Sonoran and Chihuahuan deserts (Van Devender & Spaulding, 1979; Thompson & Anderson, 2000). Refugia like these represent… Expand

Figures and Tables from this paper

Late Pleistocene to Holocene distributional stasis in scorpions along the Baja California peninsula
TLDR
Three areas of climatic suitability coincide remarkably well with genetic discontinuities in other co-distributed taxa along the BCP, indicating that long-term persistence of zones of abrupt climatic transition offer a viable alternative, or synergistic enhancement, to hypotheses of trans-peninsular seaways as drivers of peninsular divergences. Expand
Surviving in Mountain Climate Refugia: New Insights from the Genetic Diversity and Structure of the Relict Shrub Myrtus nivellei (Myrtaceae) in the Sahara Desert
TLDR
The range contraction induced by the last episode of aridification has likely increased the genetic isolation of the populations of M. nivellei, without greatly affecting the genetic diversity of the species as a whole, which is consistent with recent paleoenvironmental reconstructions. Expand
Sufficient versus optimal climatic stability during the Late Quaternary: using environmental quality to guide phylogeographic inferences in a Neotropical montane system
TLDR
Results suggest that in these tropical montane ecosystems, cycles of population connectivity and isolation followed a pattern opposite to that typically described for temperate or lowland tropical ecosystems: namely, higher connectivity during the colder glacials, with isolation in montane refugia during the interglacials, including today. Expand
Phylogeography and Ecological Niche Modeling of the Desert Iguana (Dipsosaurus dorsalis, Baird & Girard 1852) in the Baja California Peninsula
TLDR
It is found that the present climatic heterogeneity of the Baja California Peninsula has a marked influence on the population genetic structure of the species, suggesting that there are alternative explanations besides vicariance. Expand
Ecological niche and phylogeography elucidate complex biogeographic patterns in Loxosceles rufescens (Araneae, Sicariidae) in the Mediterranean Basin
TLDR
Support is found for the hypothesis that northern Africa was the center of origin for L. rufescens, and that current genetic diversity originated in allopatry, likely promoted by successive glaciations during the Pleistocene. Expand
Pleistocene refugia and their effects on the phylogeography and genetic structure of the wolf spider Pardosa sierra (Araneae: Lycosidae) on the Baja California Peninsula
TLDR
It is found that Californian populations of P. sierra diverged from peninsular populations 4 Mya, this divergence coinciding with the northern-gulf split, and there is still some uncertainty regarding the relative role of vicariance in shaping the modern biota of Baja California. Expand
Pleistocene refugia in the Chihuahuan Desert: the phylogeographic and demographic history of the gymnosperm Ephedra compacta
TLDR
The intraspecific population divergence and demographic expansion in E. compacta is probably associated with the glacial-interglacial cycles of the Pleistocene, and refugia hypotheses to explain geographical patterns of genetic diversity and phylogeographic structure in a warm North American desert that reaches inter-tropical latitudes are tested. Expand
Impact of Orogeny and Environmental Change on Genetic Divergence and Demographic History of Dipus sagitta (Dipodoidea, Dipodinae) since the Pliocene in Inland East Asia
Inland East Asia encompasses particular landscapes, including discontinuous large deserts isolated by mountains, and these landscapes have been greatly impacted by the uplift of the Qinghai-TibetanExpand
Pleistocene persistence and expansion in tarantulas on the Colorado Plateau and the effects of missing data on phylogeographical inferences from RADseq
TLDR
The profound impact of Pleistocene climates on tarantulas endemic to the Colorado Plateau, as well as the mixed nature of the region's fauna are highlighted. Expand
Peripatric speciation of an endemic species driven by Pleistocene climate change: The case of the Mexican prairie dog (Cynomys mexicanus).
TLDR
It is suggested that Pleistocene climate change had a strong impact in the distribution of these species, promoting peripatric speciation for the origin of C. mexicanus and lineage divergence within C. ludovicianus. Expand

Locating Pleistocene Refugia: Comparing Phylogeographic and Ecological Niche Model Predictions
TLDR
Comparing ENM-based reconstructions of LGM refugial locations with those resulting from the more traditional molecular genetic and phylogeographic predictions confirms that ENM scenario exploration can provide a useful complement to molecular studies, offering a less subjective, spatially explicit hypothesis of past geographic patterns of distribution.

The phylogeographical structure revealed in this study suggests complex recolonization dynamics of the European continent by V. berus, characterized by latitudinal as well as altitudinal range shifts, driven by both climatic changes and competition with related species. Expand

Evaluation of nucleotide and haplotype diversity and interpretations from NCA reveal that populations on the Colorado Plateau resulted from a recent, likely post‐Pleistocene, range expansion from the Chihuahuan Desert. Expand
