Investigating microbial communities in a spatial environment in silico suggests that spatial structure promotes higher coexistence by allowing spatial self-organization, but can hinder coexistence by weakening interactions mediated through diffusible metabolites.
Spatial segregation is identified as the primary mechanism facilitating the coexistence of apex and mesocarnivores in the Qilian Mountain National Park, China.
An individual-based model framework of sub-exponentially growing replicator systems suggests that parabolic dynamics could have been able to maintain genetic diversity and circumvent the error threshold problem during early evolution.
The growth environment driven ratio of ATP to growth rate, called absolute growth, determines the final population composition of Staphylococcus aureus and Pseudomonas aeruginosa when in co-culture.
Whereas theories of ecological diversity mostly consider continuously supplied nutrients, a seasonal model uncovers a general mechanism that controls diversity and reconciles conflicting experimental findings.
Annual crop communities are able to adapt towards reduced competition and/or increased facilitation in response to their neighboring diversity after only two generations.
A novel theory demonstrates how variation in the thermal responses of microbial populations can alter coexistance and thus explain patterns of richness across thermal gradients.
