A Window Into the Early Evolution and Diversification of Vascular Plants: The Early Devonian Posongchong Flora from Yunnan本书是对中国云南早泥盆世坡松冲植物群研究的总结,汇总并描述了早期维管植物28属37种;结合世界范围内已有工作提出了新的系统分类方案;建立了始叶蕨纲并修订了多个目级分类单元。通过沉积相和埋藏学研究,再造了早期维管植物的生活环境;提出生境的异质性是植物类群快速辐射演化的重要原因之一。在对32个性状特征分析讨论的基础上,借助于分支系统学方法(包括最大简约法和贝叶斯推论)对早期维管植物的41个样本进行了分析;识别出早泥盆世真叶植物的5个谱系;提出了枝-叶复合体的概念,它们预示着不同构型和脉序的大型叶的产生;通过多样性的动态分析,探讨了早期维管植物的宏演化模式。基于坡松冲植物群的证据,本书提出早泥盆世布拉格期“维管植物大爆发”这一假说;寒武纪海洋动物谱系大爆发奠定了海洋生物演化的壮阔之路,而泥盆纪维管植物谱系大爆发则开启了陆生植物及生态系统演化的辉煌之门。 本书适于古植物学和现代植物系统学科的科研工作者学习研究,古生物学及博物馆工作者参考,以及大专院校相关专业师生及广大自然、化石爱好者阅读。
