The paper analyzes 27 radiations using a new fossilized birth-death model to show that clade diversity follows rise and decline dynamics driven by species-level processes rather than clade-level mechanisms.

The paper introduces the Occurrence Birth-Death Diffusion process to integrate fossil data into diversification analyses, showing fossils are essential for accurate diversification rate and richness trajectory inference.

The paper compares elevational and thermal ranges of sister plant species in tropical and temperate mountains, finding tropical species have narrower thermal ranges and greater similarity between sister species, supporting speciation via thermal specialization.
