Table 3.
Results from linear regression models (Gaussian error) for the effects of warming and predation on the body length of two prey species. (The bold values indicate statistically significant effects (p < 0.05). coef. stands for regression coefficients of generalized linear models. The 95% confidence intervals (CIs) that do not overlap zero are statistically significant. Warming is used as a linear term (levels = 0, 1 and 2). HM, Hypoaspis miles; HA, Hypoaspis aculeifer.)
