    Temperature dependence of liverwort diversification reveals a cool origin and hot hotspots by Karola Maul, S. Robbert Gradstein, Dietmar Quandt, Michael Kessler

    Published 2025-01-01
    “…We conclude that the extant liverwort species diversity accumulated over long time under these climatic conditions, which are today prevailing at mid-elevations of the world’s mountains. Subsequently, liverworts expanded their ranges from these temperate areas towards warm (with high diversification rates) and cold regions (with low diversification rates), located in contemporaneous (tropical) lowlands and high mountains, respectively. …”
