Macroevolution Ng, Julienne [1], Weaver, William [1], Laport, Robert [3]. Disentangling the roles of ecological and historical processes in structuring plant communities across the United States. Communities are assembled according to a number of processes operating across spatial and temporal scales. In particular, both ecological (e.g. competitive exclusion, environmental filtering) and historical processes (e.g. speciation, dispersal) are considered central to the assembly process. However, disentangling the roles that these two processes play in shaping community structure remains a major challenge because both ecological and historical processes can give rise to similar patterns. We used a dynamic null model of assembly that incorporates historical speciation, colonization and extinction to investigate how historical processes have shaped woody perennial plant communities across the United States. Our findings reinforce the importance of including a historical perspective in analyses of community structure. Log in to add this item to your schedule
