B) genetic drift. C) selection. D) migration. 2) Adaptations are favored because. A) they help the species survive. B) they are more advanced. C) they create a balanced ecosystem. D) they promote the reproduction of the genes that code for them. Central question in community ecology. What processes are responsible for the identity and relative abundances of co-occurring species in local assemblages?. What is the relative importance of different ecological processes in structuring communities. Dwyane George. February 24, 2015. 18.434. Outline. Introduction & Motivation. Definition.
