Workshop on: "Biotic Turnover Examined in a Phylogenetic Context" PS/SVP Symposium at GSA; San Diego, CA; October 23, 1991

加州大学戴维斯分校的古生物学家桑德拉·卡尔森博士组织了一个为期半天的研讨会，题为“系统发育背景下的生物更替研究”。本次研讨会将与在圣地亚哥举行的脊椎动物古生物学家学会和古生物学会年度会议同时举行。这次研讨会将是很长一段时间以来这些学会之间的第一次联合会议，研讨会将集中讨论无脊椎动物和脊椎动物古生物学家分析化石记录中进化模式的主要差异。脊椎动物古生物学家在更大程度上接受了枝系分析，并努力重建系统发育关系和历史。相比之下，许多无脊椎古生物学家在每个地质时间间隔内对主要分类群的多样性进行了普查，并研究了多样性随时间变化的模式。只有少数人讨论了这些方法在多大程度上不相容，提议的会议将把这些负责人聚集在一起，公开讨论这个问题。本次研讨会将讨论进化古生物学中一个重要而及时的争议。这次研讨会的结果将在古生物学到进化论的研究科学家中找到感兴趣的听众。

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.
