The energy transition and its effects on biodiversity are often controversial. Prof. Sascha Buchholz, head of the Animal Ecology working group at the Institute of Landscape Ecology at the University of Münster, investigates spatial and temporal changes to biodiversity. Taking bats as an example, Kathrin Kottke spoke to him about the ways in which the challenges of protecting nature and protecting species can be reconciled with the expansion of renewable energies.
