中文摘要
小行星9317372 PI将记录新第三纪软体动物的模式,以测试假说的起源和灭绝如何变化沿着环境梯度在物种水平上,并通过比较早期的结果,在整个分类层次和从背景到大规模灭绝。 将利用数据库研究垂直和测深模式。
英文摘要
9317372 Valentine PIs will document Neogene molluscan patterns in order to test hypotheses on how origination and extinction vary along environmental gradients at the species level, and, by comparison to earlier results, across the taxonomic hierarchy and from background to mass extincttion. Latitudinal and bathymetric patterns will be examined, using databases.
