WebApr 7, 2024 · In the context of range expansions, the concepts of gene surfing, sectors, and embolisms have been invoked to explain patterns of genetic variation in a wide range of plant (53–55), animal (56, 57), and microbial populations. Our work shows that these heuristics are incomplete when long-range dispersal is present: Sectors give way to blobs ...
