Slow to change? Individual fidelity to three-dimensional foraging habitats in southern elephant seals, Mirounga leonina
Long-term fidelity to foraging areas may have fitness benefits to individuals, particularly in unpredictable environments. However, such strategies may result in short-term energetic losses and delay responses to fast environmental changes. We used satellite tracking data and associated diving data...
