  1. Resilience phenotypes pertain to specific points (P) on the population norm curve of the corresponding weather variable; summary statistics include minimum (˄), maximum (˅), Median (M), mean (μ) and standard error (SE), standard deviation (σ), and coefficient of variation (CV, expressed in percentage)
