The widespread application of high-throughput sequencing in studying evolutionary
processes and patterns of diversification has led to many important discoveries. However …

Community‐level models (CLMs) consider multiple, co‐occurring species in model fitting
and are lesser known alternatives to species distribution models (SDMs) for analysing and …

Hybrid zones are geographic regions where differentiated taxa meet and potentially
exchange genes. Increasingly, genomic analyses have demonstrated that many hybrid …

Theory suggests that traits under positive selection may introgress asymmetrically across a
hybrid zone, potentially driven by sexual selection. Two subspecies of the red-backed fairy …

Population divergence in geographic isolation is due to a combination of factors. Natural
and sexual selection may be important in shaping patterns of population differentiation, a …

When individuals mate outside the pair bond, males should employ behaviours such as
aggression or vocal displays (eg duetting) that help assure paternity of the offspring they …

Highlights•Female tree swallows have greener-coloured plumage than males.•Birds paired
to greener-coloured partners feed offspring more often.•Offspring of males that provision …

Phylogeny, ecological environment, social organisation, and mating system are expected to
affect degree of female ornamentation, either directly or indirectly, but our understanding of …

Human beings have a strong, innate desire to classify and name things. We like things to be
clear-cut. The way we approach classification of birds is as good an example as any of this …

The evolution of signalling traits is crucial in species diversification, because they can
become effective barriers to interspecific hybridization. Among various selection pressures …
