    Investigating the formation and evolution of plant diversity patterns in the Qiangtang Plateau based on phylofloristics approach by Xiaoping Li, Yun Han, Lei Miao, Hao Xu, Jingya Yu, Shuang Han, Faqi Zhang

    Published 2025-04-01
    “…Furthermore, using fossil data, we deduced that the emergence of seed plant families in this region dates back to the Cretaceous period (145.00 Ma), with a significant acceleration in evolutionary rates observed since the onset of the Quaternary Ice Age (2.00 Ma). These findings underscore the pivotal role of the uplift of the Qiangtang Plateau and the climatic shifts during the Quaternary Ice Age as primary drivers shaping the region's contemporary distribution patterns of alpine plants.…”
