NSF has funded the Post Lab to study the long-term ecological and evoutionary dynamics of secondary contact. For the next decade, the Post Lab will be studing secondary contact between landlocked and anadromous forms of alewife in Rogers Lake, CT. This project asks how climate change, anadromous alewife population recovery, and periodic major hybridization events (2-3 per decade), interact to determine the magnitude of hybridization and direction of gene flow, phenotypic differentiation among alewife forms, and whole-lake impacts. This research asks how climate change, the recovery of the anadromous alewife population, and periodic major hybridization events (2-3 per decade) interact to determine the magnitude of hybridization, the direction of gene flow, phenotypic differentiation among alewife forms, and whole-lake impacts.
