白垩纪中期隐翅虫生物多样性和古生态学研究

隐翅虫科是动物界生物多样性最高的一个科，在现代陆地生态系统中扮演着重要的角色。隐翅虫起源早，在中生代较为繁盛。之前对隐翅虫化石的研究主要集中于侏罗纪和白垩纪早期，然而对白垩纪中期翅虫辐射演化的研究程度还不高。白垩纪中期缅甸琥珀（约9900万年前）保存了丰富多样的隐翅虫，该时段隐翅虫的多样性及其古生态学意义的相关工作亟待开展。缅甸琥珀化石为研究隐翅虫这一个超大类群的早期演化和古生态学等奠定了基础。在现有的研究基础上，综合多种研究手段（激光共聚焦显微技术、显微CT），将化石与现代隐翅虫证据相结合，对琥珀隐翅虫进行系统分类研究。通过对重要类群微细特征的深入剖析，揭示其行为特征及其与周围环境的相互关系。通过对缅甸琥珀隐翅虫的组成面貌与侏罗纪、白垩纪早期以及现代类型的对比，推断隐翅虫科昆虫在长期地质历史中的演化过程。

Staphylinidae is the largest family of animals, playing an important role in today’s terrestrial ecosystems. Staphylinidae has an early origin and was diverse in the Mesozoic. Previous studies about Staphylinidae have focused on the Jurassic and Early Cretaceous forms, but its radiation in the mid-Cretaceous remains elusive. Mid-Cretaceous Burmese amber (ca. 99 Ma) harbors a rich variety of staphylinid fossils, and studies of their paleodiversity and important ecological significance during this period are urgently needed. Burmese amber fossils lay the foundation for the study of the early evolution, biogeography, and paleoecology of the hyperdiverse group. Based on our previous studies, various methods (CLSM and micro-CT) are integrated to study their paleodiversity during the late Mesozoic. Based on in-depth analyses of the morphological details of certain groups, the behaviors and their relationships with other organisms will be revealed. The evolutionary history of Staphylinidae during the long-term geological history will be inferred by comparing the insect assemblages from the Jurassic, Early Cretaceous and the present.
