Genomic structural variation rescues a classic biological invader from a population bottleneck.

Abstract excerpt

Invasion genetics presents a classic paradox: How do species successfully spread despite severe population bottlenecks? The brown treesnake (Boiga irregularis) in Guam represents a notable example of this phenomenon, having been introduced with only a handful of individuals. We show that the population endured an extreme bottleneck, with roughly half of the genome exhibiting runs of homozygosity, comparable to...
