Microorganisms live in environments that inevitably fluctuate between mild and harsh conditions. As harsh conditions may cause extinctions, the rate at which fluctuations occur can shape microbial communities and their diversity, but we still lack an intuition on how. Here, we build a mathematical model describing two microbial species living in an environment where substrate supplies randomly switch between abundant and scarce. We then vary the rate of switching as well as different properties… Expand


Strength of species interactions determines biodiversity and stability in microbial communities
Analysing communities of soil bacteria under differing nutrient concentrations, the authors show that extensive growth with high levels of nutrients results in stronger interactions among species, leading to declines in biodiversity and stability. Expand
Strength of species interactions determines biodiversity and stability in microbial communities
It is shown in microbial ecosystems in the lab that the concentrations of available nutrients can set the strength of interactions between bacteria, providing a mechanistic link between species interaction, biodiversity and stability. Expand
The rate of environmental fluctuations shapes ecological dynamics in a two-species microbial system.
A mathematical model predicted that low frequencies of change between carbon sources lead to species loss, while intermediate and high frequencies ofchange maintained both species and was experimentally confirmed by growing co-cultures in fluctuating environments. Expand
Species coexistence through simultaneous fluctuation-dependent mechanisms
Using experiments and simulations, it is shown that both mechanisms consistently affect coexistence and that, contrary to long-held assumptions, the effect of relative nonlinearity can be larger in magnitude. Expand

Overall, the importance of ecological drift appears greater in non-neutral communities than previously recognized, and varies with community size and the type and strength of density dependence. Expand

It is shown that a mathematical model based on environmental stochasticity, the Stochastic logistic model, quantitatively predicts the three macroecological laws, as well as non-stationary properties of community dynamics. Expand
Stability Criteria for Complex Microbial Communities
If microbes consume, but do not produce resources, then any positive equilibrium will always be stable to small perturbations, and it is shown that in the presence of crossfeeding, stability is no longer guaranteed. Expand
Available energy fluxes drive a transition in the diversity, stability, and functional structure of microbial communities
This work shows that complex microbial communities generically exhibit a transition as a function of available energy fluxes from a “resource-limited” regime where community structure and stability is shaped by energetic and metabolic considerations to a diverse regime where the dominant force shaping microbial communities is the overlap between species’ consumption preferences. Expand
Stability criteria for complex microbial communities
The authors explore the stability of microbial networks based on the consumption and exchange of resources, showing that asymmetry in crossfeeding relationships can destabilize networks. Expand
Environmental fluctuations and their effects on microbial communities, populations and individuals
Overall, this review finds that environmental fluctuations are ubiquitous, diverse, and strongly shape microbial behavior, ecology and evolution when compared to environments in which conditions remain constant over time. Expand
