    Strong inter-population cooperation leads to partner intermixing in microbial communities

    Babak Momeni et al.
    Simulations and experiments on systems containing two different populations of microorganisms show that interactions that benefit at least one of the populations can lead to communities with stable compositions, and that strong cooperation between two populations can lead to communities in which both populations are mixed together.

    Multistability and regime shifts in microbial communities explained by competition for essential nutrients

    Veronika Dubinkina et al.
    Multistability and regime shifts are common and species diversity is high in microbial communities when nutrient supplies are balanced and competing species have different stoichiometries of essential nutrients.

    Integrating taxonomic, functional, and strain-level profiling of diverse microbial communities with bioBakery 3

    Francesco Beghini et al.
    The bioBakery 3 platform enables improved, integrated, and strain-level analysis of microbial communities from large-scale meta-omic data.

    Cretaceous dinosaur bone contains recent organic material and provides an environment conducive to microbial communities

    Evan T Saitta et al.
    Subterranean fossil bone hosts a living microbiome different from the surrounding sediment without evidence of original protein preservation.

    Diversity and asynchrony in soil microbial communities stabilizes ecosystem functioning

    Cameron Wagg et al.
    Soil microbial diversity loss destabilizes the ability of the soil to function because greater diversity is needed to maintain temporal and functional asynchrony among different microbes.

    Stochastic logistic models reproduce experimental time series of microbial communities

    Lana Descheemaeker, Sophie de Buyl
    Properties of various microbial communities time series, such as the noise color and neutrality, are captured by stochastic generalized Lotka-Volterra equations, even in the absence of interactions.

    Lotka-Volterra pairwise modeling fails to capture diverse pairwise microbial interactions

    Babak Momeni et al.
    With mathematical modeling being an important source of insight for microbial communities, we may need to move beyond commonly-used pairwise models that do not capture microbial interactions.

    Nutrient dominance governs the assembly of microbial communities in mixed nutrient environments

    Sylvie Estrela et al.
    There are regularities in how specific nutrients combine together to shape the taxonomic composition of self-assembled communities, with some types of nutrients dominating other types.

    Extensive horizontal gene transfer in cheese-associated bacteria

    Kevin S Bonham et al.
    The identification of horizontally transferred genes, and commonly transferred functions, can provide a window into the selective forces acting on species within an ecosystem.

    Experimental evaluation of the importance of colonization history in early-life gut microbiota assembly

    Inés Martínez et al.
    Experiments in ex-germ-free mice establish a measurable effect of colonization history on gut microbiota assembly, illuminating a potential cause for the high levels of unexplained individuality in host-associated microbial communities.
