📝 My paper on generalized additive models (GAMs) in animal science is out! Learn nonlinear relationships from data, estimate growth rates and compare treatments, with cows, pigs and quail + reproducible #RStats code. Open access: doi.org/10.1016/j.an... #mgcv #AnimalScience #Statistics 🧪
Eight panels show body mass over 78 days for 57 Japanese quail. Columns represent control, T4, T3 and combined T3–T4 hormone treatments; rows separate females and males. Coloured points are measurements, lines are individual growth curves fitted by a hierarchical generalized additive model, and shading shows 95% credible intervals. Growth slows towards a plateau, with females generally reaching higher body masses than males.Eighteen panels show individual pig growth curves. Black points mark daily average weight estimates from a depth camera; blue lines show curves fitted by a hierarchical generalized additive model, with shaded 95% credible intervals. Weights generally increase over time, with differences in growth and measurement variability among pigs. Uncertainty widens where measurements are sparse or absent.Four-panel comparison of models fitted to a cow’s average daily milk fat production. Observations rise to a peak around weeks 8–10, then decline. The first panel shows fitted curves and uncertainty bands for Wood’s model, a Tweedie GLM and a Tweedie GAM. Residual plots show curved patterns for Wood’s model and the GLM, but little remaining pattern for the GAM.

‘Resilience’ has become a concept that is waved around like a magic wand in talking about responses to climate change Focussing on resilience can be unhelpful if it keeps the system in a failing state (undesirable resilience) We need to link resilience to system change rather than system inertia

Since January, I have gotten 8 desk rejections. Is this a new normal and a response to a deluge of AI-enabled papers journals are now receiving and/or dwindling availability of reviewers, or is our science not seen as novel enough (the latter I don't want to believe is true 😆)?

A sad task, well done—Brian McGill pens a tribute to Bob Ricklefs. One measure of Ricklefs’ influence: Ecology students from the 70s on were trained on “Ricklefs”: an imposing tome weaving graphs and equations together with fine, dense prose. Thanks Bob. dynamicecology.wordpress.com/2026/06/11/r...
