The geographic ranges of marine organisms, including planktonic foraminifera, diatoms, dinoflagellates, copepods and fish are already shifting poleward due to anthropogenic climate change. However, the extent to which species will move and whether these poleward range shifts represent precursor signals which lead to extinction is unclear. Understanding the development of marine biodiversity patterns over geological time and the factors that influence them are key to contextualizing these current trends. The fossil record of the macroperforate planktonic foraminifera provides a rich and phylogenetically resolved dataset that provides unique opportunities for understanding marine biogeography dynamics and how species distributions have responded to ancient climate changes. Here, we employ a bipartite network approach to quantify group diversity, latitudinal specialization, and latitudinal equitability for planktonic foraminifera over the last 8 Ma using Triton, a recently developed high-resolution global ...
