Data from: Repeated and predictable patterns of ecotypic differentiation during a biological invasion: lake-stream divergence in parapatric Swiss
- quantitative genetics;Fish;Morphometrics;population genetics;Holocene;speciation;threespine stickleback;Gasterosteus aculeatus;Adaptation
- as a consequence of adaptation, with the latter being a hallmark of ecological speciation. Ecological speciation is well studied in parts of the native range
Data from: Contemporary ecotypic divergence during a recent range expansion was facilitated by adaptive introgression
- . This illustrates how hybridization can quickly promote phenotypic divergence in a system where adaptation from standing genetic variation was constrained.
