Phylogenetic relationships of toads of the Rhinella granulosa group (Anura: Bufonidae): A molecular perspective with comments on hybridization and introgression
(2016-02-01)
The Rhinella granulosa group consists of 13 species of toads distributed throughout open areas of South America and Panama. In this paper we perform a phylogenetic analysis considering all but one species of the group, ...
The taxonomic status of the Mexican oak Quercus undata (Fagaceae, Quercus, Section Quercus)
(Revista Mexicana de Biodiversidad, 2011)
Quercus undata Trel. (Fagaceae, Quercus, Section Quercus) has a complex taxonomic and nomenclatural history. Intensive sampling of oaks at the type locality of Q. undata Trel. in Durango, Mexico and evaluation of herbarium ...
Strong postzygotic isolation prevents introgression between two hybridizing Neotropical orchids, Epidendrum denticulatum and E-fulgens
(Springer, 2015-03-01)
Studies on hybrid zones are essential to understand the origin and evolution of reproductive barriers in plants. To achieve this goal, multidisciplinary approaches are often required to investigate the role of multiple ...
Ancestral polymorphism and recent invasion of transposable elements in Drosophila species
(Biomed Central Ltd., 2012-07-23)
Background: During the evolution of transposable elements, some processes, such as ancestral polymorphisms and horizontal transfer of sequences between species, can produce incongruences in phylogenies. We investigated the ...

Phylogeny of the genus Hypophthalmus Cuvier, 1829 (Pimelodidae – Siluriformes), based on a multilocus analysis, indicates diversification and introgression in the Amazon basin
(2019-08-01)
The genus Hypophthalmus encompasses four valid South American freshwater catfish species: H. marginatus, H. edentatus, H. fimbriatus, and H. oremaculatus. More recently two new species were proposed Hypophthalmus n. sp. 1 ...
Spatiotemporally consistent genomic signatures of reproductive isolation in a moving hybrid zone
(Wiley Blackwell Publishing, Inc, 2014-11)
Studies of hybrid zone dynamics often investigate a single sampling period and draw conclusions from that temporal snapshot. Stochasticity can, however, result in loci with spurious outlier patterns, which is exacerbated ...
