How Climate Change and Invasive Fish Together Reshape Lake Ecosystems

Climate change and biological invasions are among the most significant forces reshaping ecosystems worldwide. A recent study by Leclerc et al. (2025) reveals that these drivers do not operate in isolation but are tightly intertwined, particularly in freshwater lakes. By analyzing data from 430 fish communities across 257 French lakes, the researchers demonstrated how climate-induced warming and biological invasions together influence the structure and functioning of lake food webs.
