项目摘要

This award supports a workshop at the American Museum of Natural History in May 2010 with the explicit goal of charting a path towards rectifying apparent incongruities in the paleobiogeographic and plate tectonic histories of peri-Antarctic Gondwana. The "Austral Portals" workshop is designed to bring together investigators from a broad swath of geological and biological disciplines whose interests converge on sorting out the manifold consequences of the breakup of Gondwana, with the primary goal of focusing on the newest research on the paleogeography and paleobiogeography of Antarctica and the western parts of the supercontinent (South America and Africa/India/Madagascar). One prominent reason for bringing together this group at this time is that there are several specific instances of disagreement concerning how the paleogeography of Antarctica may or may not have influenced the distribution of terrestrial biotas in the interval 140-40 Ma. Much of the relevant work has been published only in the last few years, yet largely remains unfamiliar to investigators who may be working in very different areas of scientific inquiry. Another major issue concerns the timing of the opening of para-Antarctic oceanic gateways, such as the Drake Passage, and how these seaways may have affected climate and, indirectly, the evolution of austral biotas.

该奖项于2010年5月在美国自然历史博物馆举行的研讨会，其明确的目的是为纠正抗抗抗激素周围的古地理和板块构造历史而纠正明显不一致的道路。 “澳大利亚门户”研讨会旨在将大量地质和生物学学科的调查人员汇集在一起，这些研究人员的兴趣聚集在整理冈瓦纳破裂的多种后果，其主要目的是将重点放在对南极以及南极以及南美和非洲和非洲/非洲/非洲/非洲/地区的最新研究上。目前将该群体汇集在一起的一个重要原因是，关于南极古地理的造影如何在140-40 mA间隔内影响陆地生物群的分布，存在几个具体的分歧实例。大部分相关工作仅在过去几年中才出版，但对于可能在科学探究较大领域工作的调查人员来说，很大程度上仍然不熟悉。另一个主要问题是涉及到达 - 北极海洋门户（例如Drake Passage）的时机，以及这些海道如何影响气候，并间接地影响了澳大利亚生物群落的演变。
