U.S.-Czech Paleobotanical Research on Tertiary Plant Disjunctions of North America and Europe

这个由佛罗里达大学的Steven Manchester和Charles大学的Zlatko Kvacek合作的美国-捷克研究项目将研究始新世晚期到渐新世早期在北美和欧洲的混合叶生植物（阔叶落叶）林的进化和传播。具体而言，研究人员打算研究欧洲和北美西部这些植物区系之间共有的关键属的系统关系和生物地理历史。针叶和双子叶植物的特色，即：四叶松（柏科），Platanus (Platanaceae), Asterocarpinus, Ostrya（桦木科），Tilia和Craigia （Tiliaceae）和Hooleya（核桃科）。这项为期三年的合作努力将大大受益于获得重要的中欧植物化石收藏，这些收藏在历史上很少获得。虽然结果有望澄清系统发育关系，但它们也将有助于我们了解进化在塑造现代落叶硬木组合和全球气候区带中的作用。该古植物学研究项目通过使美国和东欧的专家在共同感兴趣和能力强的领域结合互补的人才和集中研究资源，实现了推进科学知识的计划目标。?？

INT 9722444 Manchester This U.S.-Czech research project between Steven Manchester of the University of Florida and Zlatko Kvacek of Charles University will examine late Eocene to early Oligocene evolution and spread of mixed mesophytic (hardwood deciduous) forests in North America and Europe. Specifically, the researchers intend to study the systematic relationships and biogeographic history of key genera shared between these floras of Europe and western North America. Coniferous and dicotyledonous species will be featured, namely: Tetraclinis (Cupressaceae), Platanus (Platanaceae), Asterocarpinus, Ostrya (Betulaceae), Tilia and Craigia (Tiliaceae), and Hooleya (Juglandaceae). The three-year collaborative effort will benefit greatly from access to important Central European botanical fossil collections that have been historically less accessible. While results are expected to clarify the phylogenetic relationships, they will also contribute to our knowledge of the role of evolution in shaping modern deciduous hardwood assemblages and climatic zonation worldwide. This paleobotanical research project fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Eastern Europe to combine complementary talents and pool research resources in areas of strong mutual interest and competence. ??
