摘要

Mass extinctions are considered to be quintessential examples of Court Jester drivers of macro演化, whereby abiotic pressures drive a suite of extinctions leading to huge ecosystem changes across geological timescales. Most research on mass extinctions ignores 物種 interactions and community structure, limiting inference about which and why 物種 go extinct, and how Red Queen processes that link speciation to extinction rates affect the subsequent recovery of 生物多樣性, structure and function. Here, we apply 網絡 reconstruction, secondary extinction modelling and community structure analysis to the Early Toarcian (Lower Jurassic; 183Ma) Extinction Event and recovery. We find that primary extinctions targeted towards infaunal guilds, which caused secondary extinction cascades to higher 營養級 levels, repro
