Solving three core challenges in transient dynamics analysis of matrix population models

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2517-2530, October 2025.
Abstract Populations are at the mercy of random disturbances, large and small, and rarely, if ever, converge on predicted long‐term behaviours. Therefore, when using matrix population models, ecologists study the dynamics of populations that depart from stable distributions.
