Behavioural response to song and genetic divergence in two subspecies of white-crowned sparrows (Zonotrichia leucophrys).
(Molecular ecology, 2017-06)Divergence in sexual signals may drive reproductive isolation between lineages, but behavioural barriers can weaken in contact zones. Here, we investigate the role of song as a behavioural and genetic barrier in a contact ... -
Differential introgression of a female competitive trait in a hybrid zone between sex-role reversed species.
(Evolution; international journal of organic evolution, 2019-02)Mating behavior between recently diverged species in secondary contact can impede or promote reproductive isolation. Traditionally, researchers focus on the importance of female mate choice and male-male competition ... -
Genetic and phenotypic characterization of a hybrid zone between polyandrous Northern and Wattled Jacanas in Western Panama.
(BMC evolutionary biology, 2014-11)<h4>Background</h4>Hybridization provides a unique perspective into the ecological, genetic and behavioral context of speciation. Hybridization is common in birds, but has not yet been reported among bird species with a ... -
Hybrid transgenic mice reveal in vivo specificity of G protein-coupled receptor kinases in the heart.
(Circ Res, 2000-01-07)G protein-coupled receptor kinases (GRKs) phosphorylate activated G protein-coupled receptors, including alpha(1B)-adrenergic receptors (ARs), resulting in desensitization. In vivo analysis of GRK substrate selectivity has ... -
Natural hybridization between genera that diverged from each other approximately 60 million years ago.
(Am Nat, 2015-03)A fern from the French Pyrenees-×Cystocarpium roskamianum-is a recently formed intergeneric hybrid between parental lineages that diverged from each other approximately 60 million years ago (mya; 95% highest posterior density: ... -
Next-generation polyploid phylogenetics: rapid resolution of hybrid polyploid complexes using PacBio single-molecule sequencing.
(The New phytologist, 2017-01)Difficulties in generating nuclear data for polyploids have impeded phylogenetic study of these groups. We describe a high-throughput protocol and an associated bioinformatics pipeline (Pipeline for Untangling Reticulate ... -
Sex-specific incompatibility generates locus-specific rates of introgression between species.
(Genetics, 2011-09)Disruption of interactions among ensembles of epistatic loci has been shown to contribute to reproductive isolation among various animal and plant species. Under the Bateson-Dobzhansky-Muller model, such interspecific ... -
The genomic consequences of adaptive divergence and reproductive isolation between species of manakins.
(Mol Ecol, 2013-06)The processes of adaptation and speciation are expected to shape genomic variation within and between diverging species. Here we analyze genomic heterogeneity of genetic differentiation and introgression in a hybrid zone ...
