Es transmitida mosquitos y moscas, afecta células sanguíneas de sus hospederos. Actualmente, el uso herramientas moleculares ha permitido mejor detección entendimiento esta enfermedad. Las aves domésticas, cautiverio silvestres, pueden ser reservorios malaria, ya que, aunque ésta puede mortal, mayoría desarrollan manera...
Pleistocene climate cycles have been recognized to be a major driver of postglacial northward range expansion North American bird populations. During glacial maxima, allopatric lineages that were reproductively isolated might come into secondary contact with one another during periods and the genetic signatures past hybridization as result events should produce detectable hybrid zones. The white‐chested hummingbirds Amazilia violiceps A. viridifrons , constitute species complex showing...
The cloud forests of Mesoamerica are highly endangered habitats and the existence narrowly distributed cryptic endemics will increase number taxa at potential risk extinction. Here, we investigate genetic divergence between populations azure-crowned hummingbird (Amazilia cyanocephala), a species complex endemic hummingbirds to montane Mesoamerica, by analysing DNA sequences four mitochondrial markers, morphological data ecological niche modelling. Our results revealed presence two mtDNA...
Large-scale phylogeographical patterns and the underlying factors driving species divergence in Mesoamerica are poorly understood, but it is widely documented that tectonic events Pleistocene climate changes play an important role determining diversification. As glaciations developed only around high mountains, one hypothesis known effects of Last Glacial Maximum on geographical distribution genetic diversity bird populations, producing contraction/ expansion latitudinal pattern observed...
Mexico is a center of diversification for the genus Quercus, with an important number taxa occurring along Trans-Mexican Volcanic Belt (TMVB). However, impact interaction between historical and current climatic variation geological heterogeneity in TMVB on genetic phenotypic within oak species has been scarcely investigated. We used chloroplast DNA microsatellites geometric morphometrics analysis leaf shape to understand differentiation populations Quercus deserticola Trel., which inhabits...

Abstract The formation of the Trans-Mexican Volcanic Belt (TMVB) and Pleistocene climatic fluctuations have been shown to influence diversification lineages species distributed throughout central Mexico. In some taxa, however, evidence lineage is not easily recognized, as often case in reptiles. Here we present a phylogeographic study on Mexican endemic rattlesnake (Crotalus ravus), with aim understanding how distinct are across TMVB. Genetic (mtDNA) genomic (ddRADseq) data were generated...
Two sibling bare-backed bat species (Pteronotus fulvus and P. gymnonotus) have been traditionally differentiated by their size. However, intermediate specimens between the two found in sympatric populations along southern Mexico it has suggested that they may be outcome of a hybridization process species. We used one mitochondrial (COI), three nuclear markers (PRKCL, STAT5A RAG2) 13 microsatellites to explore evolutionary relationships these elucidate whether morphotypes correspond hybrid...
Global climate change is associated with changes in precipitation patterns and an increase extreme weather events, which might shift the geographic distribution of species.
