Understanding the demographic history and genetic make‐up of colonizing species is critical for inferring population sources and colonization routes. This is of main interest for designing accurate control measures in areas newly colonized by vector species of economically important pathogens. The biting midge Culicoides imicola is a major vector of orbiviruses to livestock. Historically, the distribution of this species was l...

An increasing number of studies are simultaneously investigating species diversity ( SD ) and genetic diversity ( GD ) in the same systems, looking for ‘species– genetic diversity correlations’ ( SGDC s). From negative to positive SGDC s have been reported, but studies have generally not quantified the processes underlying these correlations. They were also mostly conducted at large biogeographical scales or in recently degrad...
