PI's will continue research on the role of intrinsic factors in evolutionary rates and modes of marine invertebrates, centering on the bivalves and shelled gastropods in two regions: the Neogene (including Recent) of the eastern Pacific and the Late Cretaceous of the Gulf and Atlantic Coastal Plain. PI's will refine databases on developmental modes and geographic, stratigraphic and bathymetric ranges, add data on body size and population densities and collect more data on patterns of extinction, survival and rebound for European mollusks around the Cretaceous-Tertiary (K-T) boundary. PI's will test hypotheses on: separate and combined effects of geographic range, developmental modes, body size, population density, and preservation potential on evolutionary rates and patterns; relation of those patterns to bathymety and latitude; evolutionary trends in body size and the frequency of Cope's Rule (broadly vs narowly defined); and similarity of survivorship and rebound patterns at the K-T boundary in Europe and North America, and their relation to the background patterns as listed above.

PI将继续研究内在因素在海洋无脊椎动物进化速率和模式中的作用，以两个地区的双壳类和有壳腹足动物为中心：东太平洋的新近纪（包括近代）和海湾和大西洋沿岸的晚白垩世清楚的。 PI将完善关于发育模式和地理、地层和测深范围的数据库，添加关于体型和种群密度的数据，并收集更多关于白垩纪-第三纪（K-T）边界周围欧洲软体动物的灭绝、生存和反弹模式的数据。 PI 将测试以下假设：地理范围、发育模式、体型、种群密度和保存潜力对进化速率和模式的单独和综合影响； 这些模式与水深和纬度的关系； 体型的进化趋势和科普规则的频率（广义与狭义定义）；欧洲和北美 K-T 边界处的生存和反弹模式的相似性，以及它们与上面列出的背景模式的关系。
