For clarity, the mean LD ± s.d. are values, but statistical tests were carried out using transformed data. Regression terms are given with 95 % confidence intervals (CI), and those with the same suffix are not statistically significantly different at P <0·05. Regression terms in brackets are not significantly different from zero. *** P < 0·001.
