An interesting conundrum was recently revealed by R. Abbott when he found that the
number of hybrid zones reported in the literature for plants is very low, given the propensity …

Numerous mechanisms can drive speciation, including isolation by adaptation, distance,
and environment. These forces can promote genetic and phenotypic differentiation of local …

Hybridization provides a window into the speciation process and reshuffles parental alleles
to produce novel recombinant genotypes. The presence or absence of specific hybrid …

The contributions of divergent selection and spatial isolation to population divergence are
among the main focuses of evolutionary biology. Here we employed integrated methods to …

Hybrid zones are natural experiments for the study of avian evolution. Hybrid zones can be
dynamic, moving as species adjust to new climates and habitats, with unknown implications …

Simple Summary This review aimed to provide an exhaustive overview of the advancements
in avian SCZ research. In the review, we summarize the latest research on trait variations in …

The Notomicrus traili species group (Coleoptera: Noteridae) is a lineage of aquatic beetles
distributed throughout South America and extends into Mexico and the West Indies …

The isolated river drainages of eastern North America serve as a natural laboratory to
investigate the roles of allopatry and secondary contact in the evolutionary trajectories of …

Abstract The Great American Biotic Interchange (GABI) was a key biogeographic event in
the history of the Americas. The rising of the Panamanian land bridge ended the isolation of …

Cryptic genetic differentiation is being increasingly documented in birds and other
organisms using genome‐wide variation. A recent example of cryptic genetic differentiation …
