Cross-feeding shapes both competition and cooperation in microbial ecosystems

  title={Cross-feeding shapes both competition and cooperation in microbial ecosystems},
  author={Pankaj Mehta and Robert Marsland},
Recent work suggests that cross-feeding – the secretion and consumption of metabolic biproducts by microbes – is essential for understanding microbial ecology. Yet how cross-feeding and competition combine to give rise to ecosystem-level properties remains poorly understood. To address this question, we analytically analyze the Microbial Consumer Resource Model (MiCRM), a prominent ecological model commonly used to study microbial communities. Our mean-field solution exploits the fact that…

Stability criteria for the consumption and exchange of essential resources
A more realistic understanding of microbial metabolism is incorporated into classic mathematical models of consumer-resource dynamics and it is found that there are special types of interaction networks which remain stable even when resources are scarce.
Coexistence in diverse communities with higher-order interactions
A central assumption in most ecological models is that the interactions in a community operate only between pairs of species. However, the interaction between two species may be fundamentally changed


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.
Emergent simplicity in microbial community assembly
Monitoring the assembly of hundreds of soil- and plant-derived microbiomes in well-controlled minimal synthetic media shows that the community-level function and the coarse-grained taxonomy of the resulting communities are highly predictable and governed by nutrient availability, despite substantial species variability.
Dynamic metabolic adaptation can promote species coexistence in competitive microbial communities
It is shown that introducing dynamic metabolic strategies in consumer-resource models is necessary for reproducing experimental growth curves of the baker’s yeast Saccharomyces cerevisiae growing in the presence of two carbon sources, showing that dynamic metabolic adaptation could be an important mechanism for maintaining high levels of diversity even in environments with few energy sources.
Adaptation limits ecological diversification and promotes ecological tinkering during the competition for substitutable resources
A simple, empirically motivated model of eco-evolutionary feedback based on the competition for substitutable resources is introduced and it is found that fitness differences generate emergent selection pressures to shift metabolic effort toward resources with lower effective competition, even in saturated ecosystems.
Generic assembly patterns in complex ecological communities
This work considers a wide array of model features, including interaction types and community structures, known to generate different dynamics for a few species, and shows that equilibrium diversity, functioning, and stability can be predicted analytically using a random model parameterized by a few statistics of the community.
Decoupling function and taxonomy in the global ocean microbiome
It is found that environmental conditions strongly influence the distribution of functional groups in marine microbial communities by shaping metabolic niches, but only weakly influence taxonomic composition within individual functional groups.
Spatial ecology of territorial populations
A theoretical model of territorial resource competition with trade-offs is developed and analyzed and suggests that territorial ecosystems can display high biodiversity and rich dynamics simply due to competition for resources in a spatial community.
Statistical physics of community ecology: a cavity solution to MacArthur's consumer resource model.
It is shown how the cavity approach naturally generalizes niche theory to large ecosystems by accounting for the effect of collective phenomena on species invasion and ecological stability and highlights the important role that statistical-physics inspired approaches can play in furthering the understanding of ecology.
Stabilization of extensive fine-scale diversity by ecologically driven spatiotemporal chaos
It is argued that this spatiotemporally chaotic “phase” of coexistence of a large number of closely related strains in a chaotic state driven by ecological interactions should exist in a wide range of models, and that even in rapidly mixed systems, longer-lived spores could similarly stabilize a diverse chaotic phase.
