Abstract

Graphical AbstractIn article number 2000004 by Christian R. Voolstra and Maren Ziegler, microbiome flexibility, i.e., the potential for dynamic restructuring of the host microbiome, as a fast-response mechanism to environmental change is examined. How scales of microbiome flexibility may reflect different metaorganism adaptation mechanisms and future research directions are discussed. Adapting with microbial help may provide an alternate route to organismal adaptation that facilitates rapid responses.
