In the world of microbes, diversity plays a key role in their functions. Intraspecific diversity is the variation within a population from the same species while interspecific diversity occurs in a community made up of different species. SCELSE researchers studying mixed-species biofilms found that both types of diversity are functionally substitutable. 

Surprisingly, the more competitive morphotypic variants disturb species equilibrium in the biofilm community, leading to a less robust community that is sensitive to stress. This potentially explains why such variants are so common in the lab but very rare in the natural environment.
