Diversity of selected groups of insects in Eocene - Miocene aquatic ecosystems of Europe: analysis of systematics and paleobiogeographical data

蜉蝣目（蜉蝣目）、蜻蜓目（蜻蜓目）、豆娘目（蜻蜓目）和石蝇是翼目昆虫的基础代表。由于它们的水生幼虫，这些分类群必须与淡水结合，因此是描述水生古生态系统多样性的理想模式生物。我们的模型群是理想的生态指示生物，经常保存在波罗的海琥珀中，这将有助于更好地了解始新世至中新世的欧洲水生生态系统。然而，刻画过去生态系统的关键是化石物种组成的分类学知识，从而对过去的生活条件及其随时间的变化得出可靠的结论。该项目的主要目的是对始新世至中新世欧洲淡水古生态系统中蜉蝣、蜻蜓、豆娘和石蝇的多样性分类资料进行批判性评价。本研究的目的是：(1)重新研究欧洲始新世-中新世琥珀和沉积沉积物中有关基栖水生翼虫的系统学和分类学的所有现有资料；(2)描述欧洲几个博物馆收藏的这些不同沉积物中的新种；(3)将化石物种组成与现存动物群进行比较；(4)对基栖翅虫的古生态学、生物地理学和多样性有新的认识。

Mayflies (Ephemeroptera), dragonflies, damselflies (Odonata) and stoneflies (Plecoptera) are basal representatives of winged insects (Pterygota). Due to their aquatic larvae, these taxa are obligatorily bound to freshwater and thus ideal model organisms to describe the diversity of aquatic paleo-ecosystems. Our model groups are ideal ecological indicator organisms and frequently preserved in Baltic amber, which would make possible a better understanding of European aquatic ecosystems from Eocene to Miocene. Essential for characterising past eco-systems however is the taxonomical knowledge of the fossil species composition, enabling reliable conclusions on past living conditions and their changes in time. The main objective of this project is to critically evaluate taxonomic data on the diversity of mayflies, dragonflies, damselflies, and stoneflies in freshwater paleo-ecosystems of Europe from Eocene to Miocene. It is aimed (1) to reinvestigate all available data on the systematics and taxonomy of basal aquatic pterygotes from European eocene-micene amber and sedimentary deposits, (2) to describe new species from these different deposits hosted in several European museums, (3) to compare the fossil species composition with the extant fauna, and (4) to gain new insights into paleo-ecology, biogeography and diversity of basal winged insects.
