Model fit was assessed using the Akaike Information Criteria (AIC), smaller values indicate a better fit. The model weight is the probability that the model provides the best fit to the data; we present all models with weights greater than 0.2. Explanatory power is indicated by the r2 values from general linear models. Models use either summer or annual measures of temperature and NDVI according to which measure provided the best fit to the data in tests that used a single energy metric as a predictor (see table 1). ++++p<0.0001, +++p<0.001, ++p<0.01, +p<0.05; Negative effects −−−−p<0.0001, −−−p<0.001, −−p< 0.01, − p<0.05.
