“…In contrast to D. mollis, strong phylogeographical structure and high genetic divergence among populations were found with ITS sequences in D. miscolobium (Novaes et al, 2013), as well as in two other legume tree species with chloroplast DNA, Hymenaea stigonocarpa (Ramos et al, 2007) and Plathymenia reticulata (Novaes et al, 2010). These differences can be due to different effects of Quaternary climatic changes on D. mollis in comparison with these species, since they showed genetic evidence of strong range retraction and recent population expansion, whereas D. mollis presented only slight range retraction, with a large stable area maintained since the LGM.…”

“…In contrast, more unstable areas would exhibit lower genetic diversity due to a population bottleneck. Furthermore, because the geographical distribution of D. mollis is included in the geographic range of other Cerrado legume tree species with phylogeographical patterns which are already known (Ramos et al, 2007;Novaes et al, 2010Novaes et al, , 2013Colevatti et al, 2013b), we expected a similar phylogeographical structure for D. mollis. Since savanna species have shown evidence of range retraction during the LGM followed by expansion after climate amelioration (e.g.…”

“…Phylogeographical studies with Cerrado species have shown that Pleistocene climatic changes have shaped the demographic history of populations and the geographical range of species of plants (e.g. Collevatti et al, 2003Collevatti et al, , 2013bRamos et al, 2007;Novaes et al, 2010Novaes et al, , 2013, as well as animals (e.g. Prado et al, 2012;Santos et al, 2014;Gonzalez et al, 2015).…”

“…The few studies on phylogeography and demographic history performed with Cerrado plant species have shown some congruencies. High levels of genetic differentiation among populations, evidence of reduction in species range during the Last Glacial Maximum (LGM), and recent colonization of the southern Cerrado from northern sources were found (Collevatti et al, 2003(Collevatti et al, , 2013bRamos et al, 2007;Novaes et al, 2010Novaes et al, , 2013. Most species have also shown a striking phylogeographical structure, with a somewhat similar subdivision between groups of populations (eg.…”

Background and Aims The relative role of Pleistocene climate changes in driving the geographic distribution and genetic diversity of South American species is not well known, especially from open biomes such as the Cerrado, the most diverse tropical savanna, encompassing high levels of endemism. Here the effects of Quaternary climatic changes on demographic history, distribution dynamics and genetic diversity of Dimorphandra mollis, an endemic tree species widely distributed in the Cerrado, were investigated.Methods A total of 38 populations covering most of the distribution of D. mollis were analysed using internal transcribed spacer (ITS) sequences and nuclear microsatellite variation [simple sequence repeats (SSRs)]. The framework incorporated statistical phylogeography, coalescent analyses and ecological niche modelling (ENM).Key Results Different signatures of Quaternary climatic changes were found for ITS sequences and SSRs corresponding to different time slices. Coalescent analyses revealed large and constant effective population sizes, with high historical connectivity among the populations for ITS sequences and low effective population sizes and gene flow with recent population retraction for SSRs. ENMs indicated a slight geographical range retraction during the Last Glacial Maximum. A large historical refugium across central Brazil was predicted. Spatially explicit analyses showed a spatial cline pattern in genetic diversity related to the paleodistribution of D. mollis and to the centre of its historical refugium.Conclusions The complex genetic patterns found in D. mollis are the result of a slight geographical range retraction during the Last Glacial Maximum followed by population expansion to the east and south from a large refugium in the central part of the Cerrado. This historical refugium is coincident with an area predicted to be climatically stable under future climate scenarios. The identified refugium should be given high priority in conservation polices to safeguard the evolutionary potential of the species under predicted future climatic changes.

Premise of the StudyHistorical abiotic and biotic factors have strongly affected species diversification and speciation. Although pre‐Pleistocene events have been linked to the divergence of several Neotropical organisms, studies have highlighted a more prominent role of Pleistocene climatic oscillations in shaping current patterns of genetic variation of plants.MethodsWe performed phylogeographic analyses based on plastidial markers and modeled the current distribution and paleodistribution of Bromelia balansae (Bromeliaceae), an herbaceous species with a wide geographical distribution in South America, to infer the processes underlying its evolutionary history.Key ResultsCombined molecular and paleodistributional modeling analyses indicated retraction during the Last Glacial Maximum followed by interglacial expansion. Populations occurring in the semideciduous Atlantic Forest and the Cerrado formed two distinct genetic clusters, which have been historically or ecologically isolated since late Pliocene to early Pleistocene. Populations located in the transition zone had higher levels of genetic diversity, as expected by the long‐term climatic stability in the region detected in our ecological niche models.ConclusionsOur study adds important information on how herbaceous species have been affected by past climate in Central and Southeast Brazil, helping to disentangle the complex processes that have triggered the evolution of Neotropical biota.

Many endemic species present disjunct geographical distribution; therefore, they are suitable models to test hypotheses about the ecological and evolutionary mechanisms involved in the origin of disjunct distributions in these habitats. We studied the genetic structure and phylogeography of Tibouchina papyrus (Melastomataceae), endemic to rocky savannas in Central Brazil, to test hypothesis of vicariance and dispersal in the origin of the disjunct geographical distribution. We sampled 474 individuals from the three localities where the species is reported: Serra dos Pirineus, Serra Dourada, and Serra de Natividade. Analyses were based on the polymorphisms at cpDNA and on nuclear microsatellite loci. To test for vicariance and dispersal we constructed a median-joining network and performed an analysis of molecular variance (AMOVA). We also tested population bottleneck and estimated demographic parameters and time to most recent common ancestor (TMRCA) using coalescent analyses. A remarkable differentiation among populations was found. No significant effect of population expansion was detected and coalescent analyses showed a negligible gene flow among populations and an ancient coalescence time for chloroplast genome. Our results support that the disjunct distribution of T. papyrus may represent a climatic relict. With an estimated TMRCA dated from ∼836.491 ± 107.515 kyr BP (before present), we hypothesized that the disjunct distribution may be the outcome of bidirectional expansion of the geographical distribution favored by the drier and colder conditions that prevailed in much of Brazil during the Pre-Illinoian glaciation, followed by the retraction as the climate became warmer and moister.
