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

A pan‐European citizen science study shows population size, climate and land use are related to biased morph ratios in the heterostylous plant Primula veris
A large-scale citizen science study involving thousands of cowslip (Primula veris) observations from all over Europe revealed an unexpected prevalence of S-morphs over L-morphs, which was influenced ....

Aggregation of Leslie matrix models with application to ten diverse animal species
To determine what is lost or gained by using fewer age classes in a Leslie matrix model, I develop a novel method to reduce a Leslie matrix model to a smaller one. An aggregated (“reduced”) Leslie ma...
