Range expansion is both slower and more variable with rapid evolution across a spatial gradient in temperature

Takuji Usui,
Amy L. Angert

Abstract: Rapid evolution in colonising populations can alter our ability to predict future range expansions. Recent theory suggests that the dynamics of replicate range expansions are less variable, and hence more predictable, with increased selection at the expanding range front. Here, we test whether selection from environmental gradients across space produces more consistent range expansion speeds, using the experimental evolution of replicate duckweed populations colonising landscapes with and without a temperature… Show more
