Table 3. Standardized Regression coefficients (SRC), the min and max 95% confidence intervals, biases and standard errors (SE) of the sensitivity analysis on the calculated foraging efficiency of lactating Antarctic fur seals from energy expenditure at sea (EE in MJ), prey capture attempts (PrCA), mass (g), energy density (ED in kJ/g) and relative proportion in the diet of myctophids and cephalopods.

We omitted prey groups with SRC below 0.1 in the Table.
