In a minimalistic, generic model of competitive communities in which evolution is constrained by life-history trade-offs, stable biodiversity emerges with species adapted to different functional niches.

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.

An eco-evolutionary model shows that heterozygote advantage can maintain over 100 major histocompatibility complex alleles, providing a potent explanation for extraordinary immune gene diversity and challenges previous models that predicted limited allele coexistence.

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.

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.

Experiments in gnotobiotic bees and culture tubes can recapitulate gut microbiota coexistence patterns observed in nature.

Laboratory experiments using a microbial community and mathematical modeling reveal how environmental disturbances can predictably alter the diversity and composition of an ecosystem.

Analytical and numerical analyses reveal that the number of coexisting species exceeds the number of resource only for the structurally unstable case of linear tradeoff.
