Toward an integrative framework for microbial community coalescence

Trends Microbiol. 2023 Sep 30:S0966-842X(23)00262-7. doi: 10.1016/j.tim.2023.09.001. Online ahead of print.ABSTRACTCommunity coalescence is defined as the mixing of intact ecological communities. From river confluences to fecal microbiota transplantation, community coalescence constitutes a common ecological occurrence affecting natural and engineered microbial systems. In this opinion article, we propose an integrative framework for microbial community coalescence to guide advances in our understanding of this important - yet underexplored - ecological phenomenon. We start by aligning community coalescence with the unified framework of biological invasion and enumerate commonalities and idiosyncrasies between these two analogous processes. Then, we discuss how organismal interactions and cohesive establishment affect coalescence outcomes with direct implications for community functioning. Last, we propose the use of ecological null modeling to study the interplay of ecological processes structuring community reassembly following coalescence.PMID:37778924 | DOI:10.1016/j.tim.2023.09.001
