Unifying ecology and macroevolution with individual-based theory.

摘要: A contemporary goal in both ecology and evolutionary biology is to develop theory that transcends the boundary between two disciplines, understand phenomena cannot be explained by either field isolation. This challenging because macroevolution typically uses lineage-based models, whereas often focuses on individual organisms. Here, we a new parsimonious individual-based adding mild selection neutral of biodiversity. We show this model generates realistic phylogenies showing slowdown diversification also improves ecological predictions explaining occurrence very common species. Moreover, find distribution fitness changes over time, with average increasing at pace depends positively community size. Consequently, large communities tend produce fitter species than smaller communities. These findings have broad implications beyond biodiversity theory, potentially impacting, for example, invasion paleontology.
