Calculating biodiversity under stochastic evolutionary dynamics

作者：

Highlights：

• Extinction time is proposed as a new measure to study biodiversity driven under stochastic evolutionary dynamics.

• The state of biodiversity in stochastic dynamics differs from the deterministic dynamics, even under strong selection limit which mirrors the deterministic dynamics.

• The robustness of our results is proved under weak selection limit by forward equations.

• Our results highlight the importance of transient dynamics on biodiversity, which has been neglected in the deterministic dynamics.
