Intrinsic postzygotic barriers can play an important and multifaceted role in speciation, but
their contribution is often thought to be reserved to the final stages of the speciation process …

Ips typographus (L.) and Pityogenes chalcographus (L.)(Coleoptera: Curculionidae) are two
common bark beetle species on Norway spruce in Eurasia. Multiple biotic and abiotic factors …

Dendroctonus Erichson is a relatively small genus, but one with a disproportionately large
impact on coniferous forests. Its name is particularly suitable (Dendro-tree,-tonus destroyer) …

There are few patterns in evolution that are as rigidly held as Haldane's rule (HR), which
states,“When in the first generation between hybrids between 2 species, 1 sex is absent …

Substantial genetic variation in development time is known to exist among mountain pine
beetle (Dendroctonus ponderosae Hopkins) populations across the western United States …

Genome evolution is predicted to be rapid following the establishment of new (neo) sex
chromosomes, but it is not known if neo-sex chromosome evolution plays an important role …

Future forests are being shaped by changing climate and disturbances. Climate change is
causing large-scale forest declines globally, in addition to distributional shifts of many tree …

Chromosomal rearrangement can be an important mechanism driving population
differentiation and incipient speciation. In the mountain pine beetle (MPB, Dendroctonus …

Genome sequencing methods and assembly tools have improved dramatically since the
2013 publication of draft genome assemblies for the mountain pine beetle, Dendroctonus …

Assessments of population genetic structure and demographic history have traditionally
been based on neutral markers while explicitly excluding adaptive markers. In this study, we …
