The results of applying t-SNE on contextual information.

<p>The transformed contextual information for (A) cloned lilac and (B) common lilac.</p

Comparison of the linear modeling of the original phenological observations and the consistent phenological observations.

<p>Temporal trends in the flowering onset DOY of (A) cloned lilac, (B) common lilac, and (C) pooled observations of cloned and common lilac.</p

The geographic distribution of the clusters in context condition of cloned lilac.

Plot of inconsistent phenological observations through study area.

<p>Inconsistent volunteered observations on flowering onset DOY of (A) cloned lilac and (B) common lilac. Red points show unusually early while blue ones show unusually late phenological observation. Circles show that phenological observations from historical initiatives whereas stars show phenological observations from contemporary initiatives. Inconsistencies were labeled with the day of year that lilac started flowering.</p

The results and uncertainty of model-based clustering.

<p>Clusters of the transformed contextual information about (A) cloned lilac and (B) common lilac. The uncertainty in clustering of transformed contextual information about (C) cloned lilac and (D) common lilac. In uncertainty plot, the symbols have the following meaning: large filled symbols, 95% quantile of uncertainty; smaller open symbols, 75–95% quantile; small dots, first three quartiles of uncertainty.</p
