What is Macroecological Patterns in Coarse-grained Microbial Communities about?

Abstract Microbial communities are intrinsically hierarchical due to the shared evolutionary history of community members. This history is primarily captured through taxonomic assignment and phylogenetic reconstruction, sources of information that are frequently used to group microbes into higher levels of organization in experimental and natural communities. However, our understanding of how community diversity depends on one’s scale of observation has yet to be systematically examined. This omission is not simply a methodological detail, as the shared history of community members captured by taxonomic and phylogenetic information provides an opportunity to investigate how patterns of diversity and abundance (i.e., macroecology) are altered across scales of organization. Here, we evaluate the extent that macroecological laws endure across taxonomic and phylogenetic scales among disparate environments using data from the Earth Microbiome Project. We found that measures of biodiversity at a given scale can be consistently predicted using predictions derived from a minimal model containing zero free parameters, the Stochastic Logistic Model of growth (SLM).
