| Summary: | ABSTRACT Numerous management methods are deployed to try to mitigate the destructive impact of weedy and invasive populations. Yet, such management practices may cause these populations to inadvertently evolve in ways that have consequence on their invasiveness. To test this idea, we conducted a two‐step field mesocosm experiment; we evolved genetically diverse populations of the duckweed Lemna minor to targeted removal management and then tested the impact of that evolution in replicated invasions into experimental resident communities. We found that evolution in response to management increased invasiveness compared to populations evolved without management. This evolution in response to management had little effect on the impact of the invader on the resident species. These results illustrate the potential eco‐evolutionary consequences of management practices. Mitigating evolution to physical removal, in addition to pesticides, may be important to the long‐term success of integrated pest management. |
