- Maternal expenditure on egg care was estimated through the relative weight loss by mothers between egg laying and egg hatching. This correlation matrix was conducted using (A) uncorrected values or (B) the residuals of egg number and mean egg mass (i.e. values corrected for female weight at egg laying). The matrices above diagonal reports the correlation coefficient and the ones below diagonal the corresponding P-values, both obtained from Spearman rank correlation tests. The correlations significant after false discovery rate (FDR) corrections are in bold (see text).
