Estimating the Drivers of Diversification of Stoneflies Through Time and the Limits of Their Fossil Record

Abstract Deciphering the timing of lineage diversification and extinction has greatly benefited in last decade from methodological developments fossil-based analyses. If these advances are increasingly used to study past dynamics vertebrates, other taxa such as insects remain relatively neglected. Our understanding how insect clades waxed waned or impact major paleoenvironmental changes during their periods (mass extinction) rarely investigated. Here, we compile analyze fossil record Plecoptera (1,742 vetted occurrences) investigate genus-level diversity using a Bayesian process-based model that incorporates temporal preservation biases. We found Permian-Triassic mass drastically impacted Plecoptera, while Cretaceous Terrestrial Revolution corresponds with turnover plecopteran fauna. also unveiled three gaps record: Carboniferous-Permian transition, late Early Cretaceous, Cenomanian Bartonian, which will need be further Based on life history extant correlations between dynamic series biotic (Red Queen hypothesis) abiotic (Court Jester factors. These analyses highlight role continental fragmentation evolutionary stoneflies, is line phylogeny-based biogeographic showing vicariance drove diversification. advocates analyzing caution, attempting unveil plus likely triggers
