New paper on GBS and integrative species assessment in the spruce budworm species complex

A new paper out of the Sperling Lab has just been published in Systematic Entomology. Brunet et al (2016) clarifies species boundaries in Choristoneura fumiferana, C. occidentalis, and C. biennis using genome-wide SNPs and ecological data. These three species make up the spruce budworm species complex, and are significant conifer forest pests. The paper, which can be found here, found C. fumiferana to be genetically distinct from both C. occidentalis and C. biennis, and proposes that, due to both genetic and ecological patterns of divergence, C. biennis  should be treated as a subspecies of C. occidentalis.
