Facilitative interaction networks in experimental microbial community dynamics

The paper analyzes facilitative interactions in microbial communities using metagenomic data and metabolic modeling to identify feedback loops and keystone species.

Metagenomic analysis of ecological niche overlap and community collapse in microbiome dynamics

The paper uses metagenomic analysis to study how genetic resource-use profiles influence community collapse in microbiomes over time.

Alternative stable states, nonlinear behavior, and predictability of microbiome dynamics

This study shows that abrupt microbiome changes can be predicted using ecological concepts and stability indices in complex microbial communities.

How does the magnitude of genetic variation affect eco-evolutionary dynamics in character displacement?

The paper examines how genetic variation magnitude influences evolutionary rescue through ecological and reproductive character displacement, finding that reproductive displacement relies more on additive genetic variance.

Rapid evolution promotes fluctuation-dependent species coexistence

The paper identifies a mechanism where rapid evolution and temporal fluctuations promote species coexistence through a trade-off between competitive ability and adaptive speed.

Antagonistic coevolution between multiple quantitative traits: Matching dynamics can arise from difference interactions

The paper shows that multidimensional difference interactions with trait costs can mimic matching interactions in quantitative trait coevolution, suggesting the need to explore higher-dimensional trait spaces.

When rarity has costs: coexistence under positive frequency-dependence and environmental stochasticity

This paper analyzes how positive frequency-dependence and environmental stochasticity affect species coexistence through mathematical models.
