桑德拉·卡尔森博士，一位来自纽约大学的古生物学家， 加州戴维斯，组织了一个为期半天的研讨会，题为 “生物周转在系统发育背景下检查”。 这 专题讨论会将与年度会议同时举行， 脊椎动物古生物学家和古生物学学会 在圣地亚哥的社会。 该研讨会将是第一次联合 这些社会之间的会议在很长一段时间，和研讨会 会集中在无脊椎动物和 脊椎动物古生物学家分析了 化石记录 脊椎动物古生物学家， 更大程度上，接受了分支分析，并努力 重建系统发育关系和历史。 在 相比之下，许多无脊椎古生物学家 每个地质时间间隔内主要类群的多样性， 研究了多样性随时间变化的模式。 的程度 这些方法不兼容的问题已经得到解决， 只有几个人，拟议的会议将带来 校长们聚在一起公开讨论这个问题。 本次研讨会将讨论一个重要的和及时的 进化古生物学中的争议。 的结果 研讨会将在研究人员中找到感兴趣的听众 从古生物学到进化论。

Dr. Sandra Carlson, a paleontologists at the University of California at Davis, has organized a half-day symposium entitled "Biotic Turnover Examined in a Phylogenetic Context". This symposium will be held in conjunction with the annual meetings of Society of Vertebrate Paleontologists and the Paleontologic Society in San Diego. The symposium would be the first joint meeting between these societies in a long time, and the symposium would focus on a major difference in the ways invertebrate and vertebrate paleontologists analyze evolutionary patterns in the fossil record. Vertebrate paleontologists have, to a much greater degree, embraced cladistic analysis and have labored to reconstruct phylogenetic relationships and histories. In contrast, many invertebrate paleontologists have censused diversity within major taxa per geologic time interval and studied patterns of diversity change through time. The degree to which these approaches are incompatible has been addressed by only a few individuals, and the proposed meeting would bring the principals together for an open discussion of the issue. This symposium will address an important and timely controversy in evolutionary paleobiology. The results of this symposium will find an interested audience among research scientists from paleontology to evolutionary theory.
