Are there ecological consequences of urban adaptation? A test of eco-evolutionary dynamics in a terrestrial isopod (Oniscus asellus)

Urbanization affects many aspects of the environment with the potential to alter both ecological and evolutionary processes. However, while examples of urban evolution are accumulating, tests of urban eco-evolutionary dynamics are rare. We carried out a reciprocal transplantation experiment using the terrestrial isopod Oniscus asellus to test how adaptation to the urban heat island influenced ecological processes. As isopods are important decomposers, we asked if leaf-litter decomposition differ
