项目摘要

The rise of today’s biodiversity of insects and the general course and process of evolution of insect biodiversity during the Cenozoic are still largely unknown. The same applies for many questions concerning the historical biogeography of insects and possible interrelationships between climate change and biogeographic diversity patterns. In this study, heteropteran insects (Insecta: Heteroptera) are taken as a showcase for illuminating differences and similarities of biodiversity in different Paleogene fossil sites. A focus will lie on the investigation of the biodiversity of Eocene Heteroptera, with emphasis on the faunas from Messel (Germany) and Green River (USA). The heteropteran faunas from other early to middle Paleogene fossil sites will also be studied, including the Eckfeld maar (Germany), Menat (France) and Baltic amber (Russia and adjacent regions). Biogeographic questions concerning selected heteropteran groups will be addressed and will be put into a broader context of biogeographic history, considering both extant and fossil groups. Possible pathways of biogeographic processes and diversification will be reconstructed, relying on the base of already existent phylogenies. The comparison of different fossil sites will stimulate addressing issues concerning taphonomy and contingency. Depending on the results of the first two years the course of action for the third year of this project will be decided.

现代昆虫生物多样性的兴起以及新生代昆虫生物多样性演化的一般过程和途径尚不清楚。这同样适用于许多关于昆虫历史地理学的问题，以及气候变化和地理多样性模式之间可能的相互关系。本研究以异翅目昆虫为例，揭示了古近纪不同化石地点生物多样性的异同。重点将放在始新世异翅目生物多样性的调查，重点是梅塞尔（德国）和绿色河（美国）的动物群。也将研究其他早至中期古近纪化石地点的异翅目动物群，包括埃克费尔德马尔（德国）、梅纳特（法国）和波罗的海琥珀（俄罗斯和邻近地区）。生物地理学的问题，有关选定的异翅类群体将得到解决，并将被放入一个更广泛的背景下，考虑到现存的和化石的群体。地理过程和多样化的可能途径将被重建，依赖于已经存在的遗传学的基础。不同化石地点的比较将刺激解决有关埋藏学和偶然性的问题。根据前两年的结果，将决定该项目第三年的行动方针。
