摘要:
Time-calibrated phylogenies that contain only living species have been widely used to study the dynamics of speciation and extinction. Concerns

摘要:
We aimed to introduce and test the “seed mass–distribution range trade-off” hypothesis, that is, that range size is negatively related to seed mass
