Accomplishment-Based Renewal: Taxonomic, Evolutionary, Biogeographic and Paleoecologic Studies of Silurian- Devonian Brachiopods and Other Groups

PI开发了一个广泛的数据库， 泥盆纪问题，包括腕足类和腹足类 分类学，形态学，地理学，群落古生态学， 对比、地史、岩相和古气候 指标 本数据库资料为以下方面提供了资料： 用于地质学和生物学目的的合成物， 关于地质和生物进化的新结论 流程. 生物地理学合成在检查全球 古地理学;社区古生态学综合在 流域分析（工业和学术）和改进 涉及地理控制的地层对比;以及 进化论的研究对所有人都是有益的。 工作 大调和小调的进化含义 生物地层学的突破将提供更好的理解 群落进化、生物史、适应性辐射和 生物危机和行为关系。

The PI has developed a broad database dealing with Silurian and Devonian problems, including brachiopod and gastropod taxonomy, morphology, biogeography, community paleoecology, correlation, geologic history, lithofacies, and paleoclimatic indicators. This database material provides material for syntheses useful for geologic and biologic purposes, and for some novel conclusions about geologic and biologic-evolutionary processes. Biogeographic syntheses are useful in checking global paleogeographies; community paleoecologic syntheses are useful in basin analysis (industrial and scholarly) and improved stratigraphic correlations involving biogeographic control; and studies in evolution are useful for all. Work on the evolutionary implications of both major and minor biostratigraphic breaks will provide a better understanding of community evolution, biographic history, adaptive radiations and biotic crises, and behavioral relations.
