Candidate‐species delimitation in Desmognathus salamanders reveals gene flow across lineage boundaries, confounding phylogenetic estimation and clarifying hybrid zones [PDF]
Ecology and Evolution, 2022 Dusky Salamanders (genus Desmognathus) currently comprise only 22 described, extant species. However, recent mitochondrial and nuclear estimates indicate the presence of up to 49 candidate species based on ecogeographic sampling.

Demographic history shapes genomic ancestry in hybrid zones [PDF]
Ecology and Evolution, 2021 Demographic factors such as migration rate and population size can impede or facilitate speciation. In hybrid zones, reproductive boundaries between species are tested and demography mediates the opportunity for admixture between lineages that are ...

Hybrid zones in the European Alps impact the phylogeography of alpine vicariant willow species (Salix L.) [PDF]
Frontiers in Plant ScienceIntroductionIn the European Alps, Pleistocene climate oscillations resulted in geographical range expansions and restrictions of species. Postglacial recolonizations often result in secondary contact hybridization of vicariant species, thereby creating ...

Chorthippus parallelus and Wolbachia: Overlapping Orthopteroid and Bacterial Hybrid Zones [PDF]
Frontiers in Genetics, 2018 Wolbachia is a well-known endosymbiotic, strictly cytoplasmic bacterium. It establishes complex cytonuclear relations that are not necessarily deleterious to its host, but that often result in reproductive alterations favoring bacterial transmission ...

Quantitative Analyses of Coupling in Hybrid Zones. [PDF]
Cold Spring Harb Perspect Biol, 2023 In hybrid zones, whether barrier loci experience selection mostly independently or as a unit depends on the ratio of selection to recombination as captured by the coupling coefficient. Theory predicts a sharper transition between an uncoupled and coupled system when more loci affect hybrid fitness.

Comparative analysis of multiple hybrid zones of Rhododendron × duclouxii uncovered different potential evolutionary outcomes [PDF]
Plant DiversityThe study of natural hybridization facilitates our understanding of potential adaptive mechanisms in evolution and the process involved in speciation. In this study, we used multiple data types, including morphological traits, ddRAD-seq and ecological ...

Hybrid zones: windows on climate change. [PDF]
Trends Ecol Evol, 2015 Defining the impacts of anthropogenic climate change on biodiversity and species distributions is currently a high priority. Niche models focus primarily on predicted changes in abiotic factors; however, species interactions and adaptive evolution will impact the ability of species to persist in the face of changing climate.

Stochastic Processes and Their Applications, 2007 The authors study the interacting particle systems with behavior having an interesting interpretation in the hybrid zones sense (they concentrate on the allele frequency at the selected locus). Let \(\eta_t\) be the nonhomogeneous biased voter model on \(\mathbb{Z}^d\) where \(1\)'s are favored on \((0,\infty)\times \mathbb{Z}^{d-1}\) and \(0\)'s are ...
