  • Rapid evolution during climate change: demographic and genetic ...
    To test for rapid evolution in response to drought, we used a resurrection experiment with pedigreed individuals from three time points: prior to the prolonged drought (2011), at the end of the drought (2015) and 2 years later, after more average precipitation resumed (2017).

  • Why rapid, adaptive evolution matters for community dynamics
    Rapid evolution within the prey population, as a response to predation (i.e., changes in the frequencies of defended and undefended prey type), determines the dynamics of the predator-prey system and whether or not the polymorphism of defended and undefended prey types is maintained.
