From: Allometric scaling of the elevation of maternal energy intake during lactation

Fig. 2

Log-log plots of the relation between maternal body mass and raw data of various characteristics of maternal metabolizable energy intake (MEImat, in MJ) elevation during lactation: (a) average rate of MEImat between parturition and time to peak, (b) peak rate (points and solid line) and initial rate (dotted line) of MEImat, (c) time to peak, and (d) cumulative elevation to peak of MEImat. For each characteristic, phylogenetically-informed analysis was applied to all data points (i.e., multiple measures per species) according to the regression model \( y=a\cdot {x}^{\left({b}_1 + {b}_2\cdot { \log}_{10}x\right)} \), where coefficients b 1 and b 2 represent the linear and the quadratic effect, respectively, of maternal body mass in the log10-transformed model (log10 y = b 2 ⋅ (log10 x)2 + b 1 ⋅ log10 x + log10 a), and where the value of the normalization coefficient a depends on the diet energy density. Each panel includes the values of b 1 and b 2 (with their 95 % CI), their statistical significance, the fitted values of the phylogenetically-corrected model calculated at the average diet energy density (solid line), and the goodness-of-fit (marginal r2). Detailed model results are in Table 1
