A cis-regulatory point mutation at a R2R3-Myb transcription factor contributes to speciation by reinforcement in Phlox drummondii

This study identifies a cis-regulatory mutation in a R2R3-Myb transcription factor that contributes to reproductive isolation via reinforcement in Phlox drummondii.

A multi-dimensional selective landscape drives adaptive divergence between and within closely related Phlox species

The paper shows that natural selection drives distinct adaptive divergence between species and within populations of Phlox wildflowers, revealing different trait suites influencing fitness at these scales.

Genomics highlight an underestimation of the urban heat island effect on red oak phenology

The paper shows that urban heat island effects underestimate the impact of warming on red oak leaf-out phenology due to genetic differences between urban and rural sites.

Phylogenomic patterns of divergence and gene flow detail the evolution of reinforcement and hybrid speciation in Phlox wildflowers

This study uses phylogenomic analyses to investigate hybridization and gene flow in Phlox wildflowers, revealing hybrid speciation events and gene flow in some species.

Hybridization and introgression are prevalent in Southern European Erysimum (Brassicaceae) species

This study investigates hybridization and introgression in Southern European Erysimum species, finding widespread hybridization and polyploidization as key drivers of their evolution.

Variation in context dependent foraging behavior across pollinators

This study examines color preference flexibility in two butterfly pollinator groups under natural conditions, revealing distinct foraging behaviors that influence selection on flower color.

Correlated evolution of self and interspecific incompatibility across the range of a Texas wildflower

The paper examines self and interspecific incompatibility in Phlox drummondii, finding a significant correlation between them and suggesting shared mechanisms and geographic constraints on evolution.
