TABLE 2.

Within‐individual patterns of energy compensation. Mean background energy expenditure (${\overline{x}}_{\text{min}}$; mean value of min‐f_H for each season, beats/min) and slopes for the subset of female grey seals that were sampled over at least two seasons of study, illustrating the relationships between background and daily energy expenditure. Individuals highlighted in bold ceased lactation earlier than expected. Full results of within‐individual slopes can be found in Supporting Information Table S1
