Quantifying invasibility

The paper develops a new formula to quantify invasibility using mean growth rate and variance, validated with synthetic and empirical data.

Species coexistence and temporal environmental fluctuations: a quantitative comparison between stochastic and seasonal variations.

The paper compares the effects of environmental stochasticity and seasonal cycles on species coexistence using analytic solutions and simulations, finding periodic variations provide stronger stabilization.

Stochasticity-induced stabilization weakens in diverse communities.

The paper examines how environmental stochasticity affects community stability, finding that its stabilizing effects weaken with increasing species diversity.

Deviations from dynamic equilibrium in ecological communities worldwide

The paper shows that ecological communities worldwide exhibit changes in richness and composition larger than expected under the Dynamic Equilibrium model, driven by shared environmental responses rather than competition.

Intra-Specific variability in fluctuating environments - mechanisms of impact on species diversity

This study examines how intra-specific trait variability affects species persistence and diversity in fluctuating environments, identifying two mechanisms with opposing effects on species richness.

Mean growth rate when rare is not a reliable metric for persistence of species

The paper critiques the use of mean growth rate when rare as a metric for species persistence, showing it fails to account for stochastic environmental variations and their impact on population dynamics.

Stochasticity-induced stabilization in ecology and evolution

The paper synthesizes stochasticity-induced stabilization phenomena across ecology and evolution, showing how random environmental variation affects competitor coexistence and persistence.
