Prezygotic isolation, mating preferences, and the evolution of chromosomal inversions
Dagilis AJ, Kirkpatrick M

Recommended by Denis Roze and Thomas Broquet
The spread of chromosomal inversions as a mechanism for reinforcement

Several examples of chromosomal inversions carrying genes affecting mate choice have been reported from various organisms. Furthermore, inversions are also frequently involved in genetic isolation between populations or species. Past work has shown that inversions can spread when they capture not only some loci involved in mate choice but also loci involved in incompatibilities between hybridizing populations [1]. In this new paper [2], the authors derive analytical approximations for the select...

Introgression from related species reveals fine-scale structure in an isolated population of mussels and causes patterns of genetic-environment associations

Assessing population connectivity is central to understanding population dynamics, and is therefore of great importance in evolutionary biology and conservation biology. In the marine realm, the apparent absence of physical barriers, large population sizes and high dispersal capacities of most organisms often result in no detectable structure, thereby hindering inferences of population connectivity. In a review paper, Gagnaire et al. [1] propose several ideas to improve detection of population c...
