Spatial population genomics of a recent mosquito invasion.

Population genomic approaches can characterize dispersal across a single generation through to many generations in the past, bridging the gap between individual movement and intergenerational gene flow. These approaches are particularly useful when investigating dispersal in recently altered systems, where they provide a way of inferring long-distance dispersal between newly established populations and their interactions with existing populations. Human-mediated biological invasions represent such altered systems which can be investigated with appropriate study designs and analyses.

Dominance of the tiger: The displacement of by in parts of the Torres Strait, Australia.

Most of the inhabited islands in the Torres Strait region of Australia have experienced dengue outbreaks transmitted by at various times since at least the 1890s. However, another potential dengue vector, , the Asian tiger mosquito, was detected for the first time in 2005 and it expanded across most of the Torres Strait within a few years. In 2016, a survey of container-inhabiting mosquitoes was conducted in all island communities and was undetectable on most of the islands which the species had previously occupied, and had been replaced by .
