The R package mpmaggregate (v0.2.5) is now available on CRAN.

The package aggregates matrix population models into lower-dimensional models.

Thanks to my coauthors, Roberto Salguero-Gómez and Hiroyuki Yokomizo.

Congrats!

Why do so many female animals live longer than males? New research The fascinating exceptions in the animal kingdom to patterns of longevity.

"Males and females rarely live the same length of time. In humans, women nearly always outlive men, with an average advantage of about five years worldwide today. This pattern holds across history"

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 ....

Please let my know how I can help. I’m a musician, composer, quantitative ecologist.

Thanks for the music Peter.

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...
