Biography

Frank Berendse focuses on long-term dynamics of natural ecosystems and is fascinated by the question of why species composition in plant communities seems to be strongly stabilized while communities can change rapidly with slight changes in environmental conditions. His vision focuses on plant-plant and plant-soil interactions as key to understanding these phenomena. He has developed a mathematical theory of plant competition in non-uniform environments that explains how plant species can coexist in stochastically fluctuating environments. This concept of relative nutrient requirement among plants enables the determination of nutrient supply levels when one plant species replaces another. His approach has allowed for the calculation of critical nitrogen loads, providing a firm basis for environmental policy in Western Europe. Berendse has studied the impacts of biodiversity loss on crucial ecosystem services, demonstrating that such loss leads to lower productivity and diminished erosion resistance in sloping grasslands and embankments that protect densely populated areas from flooding. His extensive studies on feedbacks between plant life and soil have explored the interaction of dwarf birch (Betula nana) with large-scale permafrost thawing in Arctic Siberia, revealing significant negative impacts due to warming in early summer. The removal of birches has resulted in accelerated thawing and development of ponds, which has strongly increased methane emissions. Berendse is excited about investigating the beautiful ecosystems of North-European bogs and Arctic tundra, which are important parts of Europe that consist of farmland where biodiversity has dramatically declined over recent decades. He studies the European Commission's attempts to develop new agricultural policies to halt this decline and restore biodiversity, demonstrating that effective measures can be implemented.
