New Approach Helps Determine How Much Microbial Community Composition Is Driven by Selection and How Much by Chance
Quantifying the relative importance of natural selection, migration, and random shifts to a species is a major challenge in ecology research, especially for microbes. This study develops an approach named iCAMP that is based on the concept that different processes can govern different groups of species in a diverse community. Applied to grassland microbial communities, iCAMP revealed that environmental changes altered the relative importance of the ecological processes.
