This paper introduces a Phenological Threshold Model to quantify latent responses to seasonal environmental changes and demonstrates its application to black-legged kittiwake breeding data.

The paper quantifies how extreme climatic events affect genetic variance in adult survival, showing genotype-by-environment interactions that constrain adaptive potential under severe conditions.

The paper models how different plasticity components in a quantitative genetic threshold trait affect eco-evolutionary responses to environmental deterioration.
