The distribution and abundance of polyploids has intrigued biologists since their discovery in the early 20th century. A pattern in nature that may give insight to processes that shape the distribution and abundance of polyploids is that polyploid populations are sometimes associated with peripheral habitats within the range of a species of mixed p...

The kinetic skull is a key innovation that allowed snakes to capture, manipulate, and swallow prey exclusively using their heads using the coordinated movement of eight bones. Despite these unique feeding behaviors, patterns of evolutionary integration and modularity within the feeding bones of snakes in a phylogenetic framework have yet to be addr...

Spatiotemporal variation in natural selection is expected, but difficult to estimate. Pollinator-mediated selection on floral traits provides a good system for understanding and linking variation in selection to differences in ecological context. We studied pollinator-mediated selection in five populations of Dalechampia scandens (Euphorbiaceae) in...

How do male mating behaviors evolve in response to a competitive social environment? Using an experimental evolution approach, Dore et al. demonstrated that sociosexual environments can lead to the evolution of novel plastic male mating behaviors in Drosophila melanogaster, with both mating latency and mating duration extended in male-biased popula...

Animals often use assessment signals to communicate information about their quality to a variety of receivers, including potential mates, competitors, and predators. But what maintains reliable signaling and prevents signalers from signaling a better quality than they actually have? Previous work has shown that reliable signaling can be maintained ...

Sexual dimorphism can cause sexual antagonism of phenotypic traits. Lund-Hansen and colleagues (2020) investigated female-limited X chromosome evolution in Drosophila melanogaster using forced matrilineal inheritance. Body size and developmental time evolved toward their female optima, but reproductive fitness and locomotion remained unchanged. The...

How do microbial communities interact with each other? Chang et al. devised two artificial selection experiments to better characterize the function of propagule strategies in microbiomes. Consistent with previous results and with conventional evolutionary biology theory, the authors found that high group level selection was associated with high he...

"Magic traits," in which the same trait is both under divergent ecological selection and forms the basis of assortative mating, have been sought after due to their supposed unique ability to promote divergence with gene flow. Here, we ask how unique magic traits are, by exploring whether a tightly linked complex of a locus under divergent selection...

Acoustic signals show immense variation among passerines, and several hypotheses have been proposed to explain this diversity. In this study, we tested, for the first time, the relationships of song structure to phylogeny, habitat type, and morphology in the vireos and allies (Vireonidae). Every measure of song structure considered in this study ha...

How species evolve reproductive isolation in the species-rich Amazon basin is poorly understood in vertebrates. Here, we sequenced a reference genome and used a genome-wide sample of SNPs to analyze a hybrid zone between two highly cryptic species of Hypocnemis warbling-antbirds-the Rondonia warbling-antbird (H. ochrogyna) and Spix's warbling-antbi...
