Scale dependence of temporal biodiversity change in modern and fossil marine plankton
Aim Biodiversity dynamics comprise evolutionary and ecological changes on multiple temporal scales from millions of years to decades, but they are often interpreted within a single time frame. Planktonic foraminifera communities offer a unique opportunity for analyzing the dynamics of marine biodive...
