Trait-dependent diversification in angiosperms: Patterns, models and data Helmstetter, Andrew; Zenil-Ferguson, Rosana; Sauquet, Hervé; Otto, Sarah; Méndez, Marcos; Vallejo-Marin, Mario; Schönenberger, Jürg; Burgarella, Concetta; Anderson, Bruce; De Boer, Hugo; Glemin, Sylvain; Käfer, Jos
Description
<b>Abstract</b><br/>
Variation in species richness across the tree of life, accompanied by the incredible variety of ecological and morphological characteristics found in nature, has inspired many studies to link traits with species diversification. Angiosperms are a highly diverse group that has fundamentally shaped life on earth since the Cretaceous and illustrate how species diversification affects ecosystem functioning. Numerous traits and processes have been linked to differences in species richness within this group, but we know little about their relative importance and how they interact. Here, we synthesized data from 152 studies that used state-dependent speciation and extinction (SSE) models on angiosperm clades. Intrinsic traits related to reproduction and morphology were often linked to diversification but a set of universal drivers did not emerge as traits did not have consistent effects across clades. Importantly, SSE model results were correlated to dataset properties – trees that were larger, older, or less well-sampled tended to yield trait-dependent outcomes. We compared these properties to recommendations for SSE model use and provide a set of best practices to follow when designing studies and reporting results. Finally, we argue that SSE model inferences should be considered in a larger context incorporating species' ecology, demography and genetics.</p>
