  • Toxoplasma gondii can infect all warm-blooded animals, with felidae being the definitive hosts. Despite this broad host range, most clinical and animal isolates belong to few clonal lineages. Here, Galal et al. perform whole-genome sequencing of isolates from distinct geographical regions and estimate T. gondii mutation rate and generation time. They find that recent waves of migration disseminated the parasite from Old to New World and identify a unique haplotype that likely accompanied the global expansion of cats and is today common to all intercontinental lineages and hybrid populations.

  • Populations of the same species living in different habitats can differ in sensory traits driving speciation, but it is not known if this variation limits gene flow. Here, a genetic and acoustic study of the bumblebee bat suggests that geographic distance, instead of echolocation divergence, limits gene flow.
