If fitted alone as predictor, the date function had a highly significant effect on nymph density ( χ 2 = 485, df = 6, P < 0.001), and the AIC of the resulting model was 1095.6.

SD or its quadratic term were not found to be significant at any time scale, but only showed a trend in the model using daily mean values (daily mean of SD: χ 2 = 3.38, df = 1, P = 0.066, AIC = 1094.2).
