“…Considering recent documentation of potential mitochondrial recombination events in mammals (31), we tested for mitochondrial recombination among these species, and our results failed to identify potential mitochondrial recombination among A. jamaicensis, A. planirostris, and/or A. schwartzi (SI Materials and Methods). Additionally, previous analyses have rejected incomplete lineage sorting with regard to A. schwartzi mtDNA haplotypes (32).…”

Most diploid species arise from single-species ancestors. Hybrid origins of new species are uncommon (except among polyploids) and are documented infrequently in animals. Examples of natural hybridization leading to speciation in mammals are exceedingly rare. Here, we show a Caribbean species of bat (Artibeus schwartzi) has a nuclear genome derived from two nonsister but congeneric species (A. jamaicensis and A. planirostris) and a mitochondrial genome that is from a third extinct or uncharacterized congener. Artibeus schwartzi is self-sustaining, morphologically distinct, and exists in near geographic isolation of its known parent species. Island effects (i.e., area, reduced habitat variability, and geographic isolation) likely have restricted gene flow from parental species into the Caribbean populations of this hybrid lineage, thus contributing to local adaptation and isolation of this newly produced taxon. We hypothesize differential rates of the development of reproductive isolation within the genus and estimate that 2.5 million years was an insufficient amount of time for the development of postzygotic isolation among the three species that hybridized to produce A. schwartzi. Reticulated evolution thus has resulted in a genomic combination from three evolutionary lineages and a transgressive phenotype that is distinct from all other known species of Artibeus. The data herein further demonstrate the phenomenon of speciation by hybridization in mammals is possible in nature.Artibeus | Chiroptera | hybrid speciation | reticulate evolution | transgressive segregation D espite empirical studies documenting the establishment of animal hybrid lineages (1-8), the evolutionary importance of speciation by natural hybridization in animals is unknown and often is considered minor because the offspring of such crosses typically are less fit than either parental species (9, 10). Nearly all reported cases of homoploid speciation events (hybrid speciation without change in chromosome number) (11) in animals are among species of insects or fish (12), and there are only a handful of suspected cases in mammals (13-17). Thus hybrid speciation appears to be especially rare in mammals, a consequence of either unfavorable conditions for hybrid speciation to occur (i.e., ecological, physiological, hybrid zone structure) or a lack of empirically based research (18,19). Here, we describe a zone of admixture on a series of Caribbean islands within which three species of Neotropical bats have hybridized resulting in a novel lineage with species-level distinction. Our genetic and morphometric analyses have identified a unique hybrid zone among species of fruit-eating bats, leading us to the hypothesis that natural hybridization has generated a distinct lineage that exists in these insular populations. Our data also indicate that this phenotypic and genotypic combination is geographically isolated from extant parental species on the southern Lesser Antillean island of Saint Vincent.Two species of fruit-eating bats, Artibeus jamaicensis...

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.

“…Es esencialmente frugívoro, y se alimenta de una amplia variedad de especies vegetales (Studier et al 1983); pero si estos recursos son escasos puede consumir néctar, insectos y polen (Ortega & Castro-Arellano 2001). Lo anterior permite que generalmente A. jamaicensis no se vea afectado por la perturbación y fragmentación de sus hábitats, lo cual se refleja en su alta diversidad gené-tica y alto flujo génico (Carstens et al 2004;Vázquez-Domínguez et al 2013).…”

RESUMEN. La deforestación de las selvas provoca la fragmentación de los hábitats, lo cual interviene en la composición, abundancia y demografía de las especies, y por lo tanto, en el aislamiento poblacional en muchas especies. Los impactos de la fragmentación dependerán de la capacidad de respuesta de las especies a los disturbios en su há-bitat, y de la configuración y estructura del paisaje. En algunas poblaciones, la fragmentación del hábitat puede provocar el aislamiento poblacional a largo plazo, por la reducción del tamaño poblacional y el debilitamiento de relaciones entre individuos, aún en especies de alta movilidad como los murciélagos. En México, A. jamaicensis es de los murciélagos más estudiados; sin embargo, son pocos los trabajos enfocados en conocer los impactos de la modificación de su hábitat, en su diversidad y estructura genética. Por lo tanto, el objetivo de este trabajo fue evaluar la diversidad, la estructura y la diferenciación genética, así como analizar la historia demográfica de A. jamaicensis en dos hábitats diferentes, utilizando un fragmento de 396 pb de la región mitocondrial D-loop. La red de haplotipos reveló 34 haplotipos únicos de 34 individuos analizados. La diversidad haplotípica fue alta (h = 1) para ambas poblaciones, y la diversidad nucleotídica fue relativamente baja (< 0.03). El análisis de la distribución de diferencias nucleotídi-cas pareadas (distribución mismatch), y los valores negativos de los estadísticos basados en pruebas de neutralidad, sugieren un proceso de expansión demográfica reciente y repentina de A. jamaicensis. Una moderada diferenciación genética apunta a que existe estructura gené-tica de A. jamaicensis. Palabras clave: D-loop, diversidad genética, estructura, haplotipos, historia demográfica. ABSTRACT. Deforestation causes fragmentation of habitats, which in turn affects the composition, abundance and demography of species, and therefore the population isolation of many species. The impacts of fragmentation will depend on the responsiveness of the species to disturbances in their habitat, and the configuration and structure of landscape. In some populations, habitat fragmentation can cause long-term population isolation by the reduction in population size and the weakening of relations between individuals, even in highly mobile species like bats. In Mexico, A. jamaicensis is the most studied bat; however, few studies focused on the knowledge of the impacts of habitat modification in its diversity and genetic structure. Therefore, the objective of this study was to evaluate the diversity, structure and genetic differentiation, and analyze demographic history of A. jamaicensis in two different habitats, using a 396 bp fragment of the mitochondrial Dloop region. Haplotype network revealed 34 unique haplotypes of 34 individuals analyzed. Haplotype diversity was high (h = 1) for both populations, and nucleotide diversity was relatively low (< 0.03). The analysis of the distribution of pairwise differences between sequences and negative values of statisti...
