This paper introduces S-elasticity, a second-order elasticity measure to analyze nonlinear fitness responses to vital rate perturbations in ecology and evolution.

The paper uses Bayesian models to show that population responses to environmental stochasticity vary widely and are driven by survival-reproduction trade-offs and aridity.

The paper tests the social buffering hypothesis across 66 animal species, finding social species have lower demographic sensitivity to environmental variability, especially in unpredictable climates.
