This study shows that speciation history influences sympatric species richness in birds, with older clades having higher richness due to longer time for species to accumulate in sympatry.

This study analyzes species-area relationships (SARs) in tetrapods across the Cretaceous-Paleogene extinction, showing changes in SAR slope and intercept that contradict expected patterns of homogenization and diversity loss.

This study shows that bird beak and body shapes are constrained by biophysical trade-offs, leading to specialized forms and faster evolutionary turnover at the extremes of morphospace.

This study shows that apparent negative scaling between diversification rates and time in fossils is caused by sampling bias, not real evolutionary trends.
