Figure 2: Population-specific coefficients for onset~latitude when data aggregation is latitude*year as related to the number of latitudes with latitude*year onset metrics for that population (requiring at least 5 occurrence records in a given latitudinal band and year). Coefficients for extreme value metrics (circles) and weibull metrics (Xs) are colored such that green represents coefficients with p≤0.05 and gray represents p>0.05. Model results for data curations 1 & 2, extreme and weibull metrics, and models with and without effort metrics are shown for each population. From 29 populations in which at least 5 latitudes are represented in population phenometrics, onset is significantly later at higher latitudes for 22 (extreme value metrics) or 24 (weibull metrics) populations.
