Do different rates of gene flow underlie variation in phenotypic and phenological clines in a montane grasshopper community?

Sean Schoville, Rachel Slatyer, César Nufio & Lauren Buckley
Species responses to environmental change are likely to depend on existing genetic and phenotypic variation, as well as evolutionary potential. A key challenge is to determine whether gene flow might facilitate or impede genomic divergence among populations responding to environmental change, and if emergent phenotypic variation is limited by gene flow rates. A general expectation is that patterns of genetic differentiation in a set of co-distributed species reflect differences in dispersal ability. In less-dispersive species,...
