Species distributed across vast continental areas and major biomes provide unique model systems for studies of biotic diversification, yet also constitute daunting financial, logistic political challenges data collection such regions. The tree frog Dendropsophus minutus (Anura: Hylidae) is a nominal species, continentally in South America, that may represent complex multiple each with more limited distribution. To understand the spatial pattern molecular diversity throughout range this...
Parsley frogs (Pelodytes) comprise the only genus in family Pelodytidae, an ancient anuran lineage that split from their closest relatives over 140 million years ago. Pelodytes is a Palearctic group restricted to Western Eurasia including three extant species: eastern species P. caucasicus, endemic Caucasus area, and two closely related inhabiting Europe: Iberian ibericus more widespread punctatus. Previous studies based on mitochondrial nuclear DNA markers have revealed existence of...
Many studies propose that Quaternary climatic cycles contracted and/or expanded the ranges of species and biomes. Strong expansion-contraction dynamics biomes presume concerted demographic changes associated fauna. The analysis temporal concordance can be used to test influence climate on diversification processes. Hierarchical approximate Bayesian computation (hABC) is a powerful flexible approach models genetic data from multiple species, estimate Using available single-locus data, we now...
Most phylogenies are typically represented as purely bifurcating. However, genomic data have become more common in phylogenetic studies, it is not unusual to find reticulation among terminal lineages or internal nodes (deep time reticulation; DTR). In these situations, gene flow must happened the same adjacent geographic areas for DTRs occurred and therefore biogeographic reconstruction should provide similar area estimates parental nodes, provided extinction dispersal has eroded patterns....
Abstract Genetic structure can be influenced by local adaptation to environmental heterogeneity and biogeographic barriers, resulting in discrete population clusters. Geographic distance among populations, however, result continuous clines of genetic divergence that appear as structured populations. Here, we evaluate the relevant importance these three factors over a landscape characterized presence hypothesized barrier producing within 13 codistributed snake species using genomic data set....
Abstract Geographic barriers are frequently invoked to explain genetic structuring across the landscape. However, inferences on spatial and temporal origins of population variation have been largely limited evolutionary neutral models, ignoring potential role natural selection intrinsic genomic processes known as architecture in producing heterogeneity differentiation genome. To test how characteristics (e.g. recombination rate) impacts our ability reconstruct general patterns between...
Abstract The South American Dry Diagonal, also called the Diagonal of Open Formations, is a large region seasonally dry vegetation extending from northeastern Brazil to northern Argentina, comprising Caatinga, Cerrado, and Chaco subregions. A growing body phylogeography literature has determined that complex history climatic changes coupled with more ancient geological events produced diverse endemic‐rich biota. However, exact drivers are still under investigation, their relative strengths...
Abstract Two main hypotheses have been proposed to explain the diversification of Caatinga biota. The riverine barrier hypothesis ( RBH ) claims that São Francisco River SFR is a major biogeographic gene flow. Pleistocene climatic fluctuation PCH states flow, geographic genetic structure and demographic signatures on endemic taxa were influenced by Quaternary climate cycles. Herein, we analyse diversity structure, phylogeographic history, widespread lizard Cnemidophorus ocellifer based large...
Abstract Divergence dating analyses in systematics provide a framework to develop and test biogeographic hypotheses regarding speciation. However, as molecular datasets grow from multilocus genomic, sample sizes decrease due computational burdens, the testing of fine-scale becomes difficult. In this study, we use coalescent demographic models investigate diversification poorly known rice paddy snakes Southeast Asia (Homalopsidae: Hypsiscopus ), which have conflicting dates origin based on...
Inferring the history of divergence between species in a framework that permits presence gene flow has been crucial for characterizing "gray zone" speciation, which is period time where lineages have diverged but not yet achieved strict reproductive isolation. However, estimates both times and rates often ignore spatial information, example when considering location width hybrid zones with respect to changes environment lineages. Using population genomic data from North American ratsnake...
Abstract For many species, climate oscillations drove cycles of population contraction during cool glacial periods followed by expansion interglacials. Some groups, however, show evidence uniform and synchronous expansion, while others display differences in the timing extent demographic change. We compared histories inferred from genetic data across marine turtle species to identify responses postglacial warming shared taxa examine drivers past change at global scale. Using coalescent...
The Leptodactylus latrans species group currently comprises eight medium- to large-sized frog with a convoluted taxonomic history, particularly related the specific limits of L. complex, and pair chaquensis–Leptodactylus macrosternum. Their homogeneous external morphology continental geographic distribution in South America have posed severe limitations comprehensive review, such that consensus remain uncertain. This is further worsened by presence chromatic polymorphism among coexisting can...
The Pleistocenic Arc Hypothesis (PAH) posits that South American Seasonally Dry Tropical Forests (SDTF) were interconnected during Pleistocene glacial periods, enabling the expansion of species ranges subsequently fragmented in interglacial promoting speciation. lizard genus Lygodactylus occurs Africa, Madagascar, and America. Compared to high diversity African Lygodactylus, only two are known occur America, L. klugei wetzeli, distributed SDTFs Chaco, respectively. We use a phylogenetic...
We aim to evaluate the genetic structure of an Atlantic Forest amphibian species, Scinax eurydice, testing congruence among patterns identified and proposed by literature for Pleistocene refugia, microrefugia, geographic barriers gene flow such as major rivers. Furthermore, we predictions refugia on presence/absence dispersal, timing since separation, population expansions/contractions. sequenced mitochondrial nuclear markers 94 tissue samples from 41 localities. inferred a tree estimated...
Abstract Aim Phylogeographic studies show how historical and current changes in landscapes shape the geographic distribution of genetic diversity species animals plants. In particular, for Diagonal Open Formations (DOF), compartmentalization Central Brazilian Plateau (CBP) during Tertiary climatic oscillations Quaternary have often been invoked to explain origin patterns biodiversity. We investigated landscape shaped diversification history a widespread South American treefrog. Location...
Many phylogeographic studies on species with large ranges have found genetic-geographic structure associated changes in habitat and physical barriers preventing or reducing gene flow. These interactions geographic space, contemporary historical climate, biogeographic complex effects population genetic processes of speciation. While allopatric speciation at is considered the primary mechanism for generating species, more recently it has been shown that parapatric modes divergence may be...
Species are being lost at an unprecedented rate during the Anthropocene. Progress has been made in clarifying how species traits influence their propensity to go extinct, but role historical demography plays loss or persistence is unclear. In eastern North America, five charismatic landbirds went extinct last century, and causes of extinctions have heavily debated. Although these most often attributed post-colonial human activity, other factors such as declining ancestral populations prior...
