古地理格局调控显生宙海洋灭绝风险

Cooper M. Malanoski1*, Seth Finnegan2,4, Edward C. Huang3, Lila Blake1, Connal Mac Niocaill1, Erin E. Saupe1* understanding the factors that have influenced the intensity and selectivity of extinction throughout Earth’s history is important for explaining past biodiversity change and forecasting biotic responses to environmental change. Here, we investigated the role of coastline geometry and paleogeographic boundary conditions in shaping extinction risk for shallow- marine taxa over the past 540 million years. We show that interactions between the geographic distributions of taxa and the geometric configurations of continental margins consistently predict relative extinction risk: Taxa with potential dispersal pathways that are long relative to the range of latitude traversed—such as those that occur along east- west–oriented coastlines, islands, or inland seaways—consistently …
