Chrysochus paper accepted!

Our Chrysochus hybrid zone paper was accepted at the Journal of Evolutionary Biology. We provide a direct link between cryptic barriers studied in the lab over a range of heterospecific mating frequencies, and hybrid zone dynamics.

Reproductive barriers are often assumed to arise from fixed genetic differences between species, despite frequent individual variation in the strength of reproductive isolation between populations. Larson et al. report polymorphism at several hybrid male sterility loci in house mice, and their results demonstrate that selection against deleterious hybrid interactions can drive the introgression of hybrid incompatibilities, highlighting the need for more extensive sampling of natural variation in speciation studies.

Spermatogenesis and the Evolution of Mammalian Sex Chromosomes

Erica L. Larson, Emily E.K. Kopania, and Jeffrey M. Good  

Developmental constraint and sexual conflict shape the evolution of hetero- morphic sex chromosomes. These contrasting forces are perhaps strongest during spermatogenesis in species with XY males. In this review, we consider how the unique regulatory environment and selective pressures of spermato- genesis interact to impact sex chromosome evolution in mammals. We explore how each developmental phase of spermatogenesis influences sex chromo- some gene content, structure, and rate of molecular evolution, and how these attributes may contribute to speciation. We argue that a developmental context is fundamental to understanding sex chromosome evolution and that an evolutionary perspective can shed new light on our understanding of sperm development. PAPER
