Early Pleistocene ecosystem turnover in South Siberia linked to abrupt regional cooling

Key Points

• Ecosystem turnover occurs alongside a significant regional cooling, indicating an ecosystem response to climate change.
• A notable cooling phase correlates with changes in vegetation and animal species composition during the Early Pleistocene.
• Observational analysis across regions in South Siberia identifies instances of abrupt climate shifts influencing ecosystem dynamics.
• Findings suggest that climatic changes have played a critical role in shaping historical ecosystems in the region.
