Chromosomal inversions can limit adaptation to new environments

The paper explores how chromosomal inversions can both aid and hinder adaptation to changing ecological conditions by limiting the formation of optimal allele combinations.

Gene flow biases population genetic inference of recombination rate

This study shows gene flow can bias LD-based recombination rate estimates by 20-50%, affecting detection of interpopulation differences.

Ancestral reconstruction of sunflower karyotypes reveals non-random chromosomal evolution

The paper reconstructs ancestral sunflower karyotypes and finds a high rate of chromosomal rearrangement with non-random translocations contributing to hybrid sterility.

Adaptive introgression during environmental change can weaken reproductive isolation

The paper shows that adaptive introgression during environmental change can weaken reproductive isolation, leading to the decay of species boundaries.

Evolutionary dynamics of recent selection for enhanced social cognition

This study shows that recent evolution of visual individual recognition in paper wasps is driven by strong positive selection on genes related to memory and visual processing.
