项目摘要

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. ??

INT 9722444曼彻斯特这个美国-佛罗里达大学的Steven Manchester和查尔斯大学的Zlatko Kvacek之间的捷克研究项目将研究始新世晚期到渐新世早期的进化和北美和欧洲中生混合（硬木落叶）森林的传播。具体来说，研究人员打算研究欧洲和北美西部这些植物区系之间共享的关键属的系统关系和植物地理学历史。将展出针叶和双子叶物种，即：Tetraclinis（柏科）、悬铃木属（悬铃木科）、Asterocarpinus、Ostrya（桦木科）、Tilia和Craigia（椴树科）和Hooleya（胡桃科）。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，这些收藏在历史上是不太容易获得的。虽然结果有望澄清的系统发育关系，他们也将有助于我们的知识，在塑造现代落叶阔叶树组合和全球气候地带性的演变的作用。这个古植物学研究项目通过使美国和东欧的专家能够联合收割机互补的人才和在强烈的共同兴趣和能力领域集中研究资源来实现推进科学知识的计划目标。 ??
