Table 2.
Standard least squares mixed model results at different spatial scales with flowering DOY as the response variable, species as a random effect, and May, June, July, and August mean temperatures as fixed effects, showing June mean temperature generally had the strongest correlation with the time of flowering and models have better fit at finer spatial scales
