“…4, 5). This pattern was also found for the QM lineage of F. quadranus (Wang et al 2012), as well as several other temperate species in North America and Europe (e.g., Milá et al 2006Milá et al , 2007Kvist et al 2004;Burg et al 2005;Fontanella et al 2008;Guiher and Burbrink 2008), but differed from that of other vertebrate species with wider distribution in East Asia that experienced population growth before the LGM Song et al 2009;Ding et al 2011). Nonetheless, like other species Song et al 2009;Ding et al 2011;Wang et al 2012), most lineages of F. taihangnica might have sustained stable effective population size during the mid-late Pleistocene (Fig.…”

Phylogeographic Patterns of mtDNA Variation Revealed Multiple Glacial Refugia for the Frog Species Feirana taihangnica Endemic to the Qinling Mountains

Diversification patterns and demography of montane species are affected by Pleistocene climate fluctuations. Empirical cases from the Qinling Mountains (QM) region, which is a major biogeographic divider of East Asia, are few. We used DNA sequence data of the complete mitochondrial ND2 gene to detect effects of the Pleistocene glaciations on phylogeographic profiles of a frog species, Feirana taihangnica, which is endemic to the QM. Four distinct lineages consisting of seven sublineages were revealed. The strongest signal of biogeographical structure (F ct = 0.971, P \ 0.01) was found when populations were grouped according to these seven sublineages. One narrow secondary contact zone was detected in the middle QM between the lineage from middle QM and the lineage from eastern QM. Coalescent simulations indicated that this species colonized the QM region by a stepping-stone model. Divergences among lineages had likely been influenced by the uplift of the Tibetan Plateau during the late Miocene-tolate Pleistocene, as well as by the Pleistocene climatic cycles. Coalescent simulations also suggested that F. taihangnica populations have persisted through the Pleistocene glacial periods in multiple refugia across the QM region. Demographic analyses indicated that all lineages, except the lineage in the Funiu Mountains, have been experienced postglacial expansion of population size and distribution range. In conclusion, Pleistocene climate fluctuations and tectonic changes during the late Miocene-late Pleistocene have profoundly influenced the phylogeography and historical demography of F. taihangnica.

“…Although some species persisted through periods of climatic change, population sizes may have been drastically reduced (e.g., [5]). In contrast, when conditions become favorable, population sizes for some species increased rapidly (e.g., [6–9]; reviewed in Hewitt [4,10–12]).…”

“…Open pine-forest habitat was predominant across western NA and the deserts of the southwest were cooler and wetter compared to current climates [33]. Several studies have found that after the LGM, temperate North American species expanded as more suitable habitat became available (e.g., pitvipers [9], woodpeckers [34], and rodents [35]). These climate changes may have also contributed to the diversification of species by isolating once contiguous populations into separate southern refugia [4,11,12,36,37].…”

The effects of Late Quaternary climate change have been examined for many temperate New World taxa, but the impact of Pleistocene glacial cycles on Neotropical taxa is less well understood, specifically with respect to changes in population demography. Here, we examine historical demographic trends for six species of milksnake with representatives in both the temperate and tropical Americas to determine if species share responses to climate change as a taxon or by area (i.e., temperate versus tropical environments). Using a multilocus dataset, we test for the demographic signature of population expansion and decline using non-genealogical summary statistics, as well as coalescent-based methods. In addition, we determine whether range sizes are correlated with effective population sizes for milksnakes. Results indicate that there are no identifiable trends with respect to demographic response based on location, and that species responded to changing climates independently, with tropical taxa showing greater instability. There is also no correlation between range size and effective population size, with the largest population size belonging to the species with the smallest geographic distribution. Our study highlights the importance of not generalizing the demographic histories of taxa by region and further illustrates that the New World tropics may not have been a stable refuge during the Pleistocene.

“…3). Therefore, we conclude that unlike those of many other vertebrates Castoe et al, 2007;Guiher and Burbrink, 2008;Hewitt, 2000Hewitt, , 1996 these population sizes were not negatively affected by major climate changes. This agrees with other research on high-elevation vertebrates ranging outside the direct area of inundation by North American glaciers, where population sizes were not negatively impacted by Pleistocene climate change Burbrink, 2008, 2009).…”
