Method synopsis

Simulation experiment using skew-normal density distributions to quantify the potential impact of skewness differences on species overlap. Parameter space is systematically explored to find maximum possible overlap between distributions with different skewness values.

Steps below were extracted from the paper that introduces this protocol — Skewness in bee and flower phenological distributions (2023), Ecology. Implementations in other papers (listed below) may differ.

1. Overlap simulation experiment
   To demonstrate potential phenological match/mismatch consequences of skewness differences, the maximum possible overlap of distributions with different skews was simulated. Pairs of skew-normal density distributions were repeatedly generated with two different skewness parameters, representing phenological distributions of one flower species and one bee species. The mean and standard deviation of one distribution was perturbed in 2000 total parameter combinations to find the maximum possible overlap.
   Quantities: 2000 parameter combinations tested, 2500 total comparisons (50² skewness values sequenced evenly between -5 and 5), calculated largest possible overlap of paired distributionsDuration: Computational simulation processConditions: Allowing mean and SD to vary freely while maintaining skewness differences
   Equipment: skew-normal density distribution functions, computational software
