- † General linear models were used to analyze parametric data and 2 Mann-Whitney's tests were used to analyse Glycogen's non-normally distributed data (interaction not tested).
- Statistical analyses of the effects of female phenotypic quality and water availability on physiological and metabolite parameters at the end of the 7 d hydric stress manipulation period. All parameters were corrected for body size (see methods for details). P-values are * P < 0.05, ** P < 0.01, *** P < 0.001, NS not significant.
