Analysing the complex interplay of processes controlling biodiversity is fundamental for understanding how diversity is maintained, depleted, or increased, and for assessing the evolutionary response of organisms to global change. Knowing the factors that control evolutionary rates (i.e. rates of origination and of extinction), and thus diversity, is both of great scientific interest and of relevance to society. I propose to study the diversity dynamics of marine bivalves, which can serve as a model group due to their great ecological variety and rich fossil record. By utilising the Paleobiology Database, we calculate taxon-specific evolutionary rates for monophyletic bivalve clades. Furthermore, we will investigate rates for bivalve subgroups that share certain biological traits (geographic range, abundance, niche breadth, body size, life habit, trophic group, mobility, shell mineralogy), and environmental preferences (e.g. for tropical versus non-tropical climatic zones, carbonate versus siliciclastic substrates, reefs versus level-bottom communities etc.). By doing so we expect new insights into the relative role of various intrinsic biological features and extrinsic, biotic and abiotic conditions of the environment in shaping the diversification of a major component of marine benthic ecosystems.

分析控制生物多样性的过程的复杂相互作用是了解多样性是如何维持，耗尽或增加，并评估生物体对全球变化的进化反应的基础。了解控制进化速率（即起源和灭绝的速率）的因素，从而了解多样性，既有巨大的科学兴趣，也与社会有关。我建议研究海洋双壳贝类的多样性动态，由于它们的生态多样性和丰富的化石记录，可以作为模式群。通过利用古生物学数据库，我们计算了单系双壳类分支的分类特异性进化率。此外，我们将调查具有某些生物特征（地理范围，丰度，生态位宽度，体型，生活习性，营养组，流动性，贝壳矿物学）和环境偏好（例如热带与非热带气候带，碳酸盐与硅质基质，珊瑚礁与底层群落等）的双壳类亚组的比率。通过这样做，我们期望对环境的各种内在生物特征和外在、生物和非生物条件在形成海洋底栖生态系统的一个主要组成部分的多样化方面的相对作用有新的认识。
