Fig 3a: Predators responses to prey depth distribution and numbers of aggregation. (A & B) Dive efficiency by bottom-dive-cycle ratio (BDCr; A. torda DE=18%, pddepth=1%, pdagg =2%, pddepth* pdagg =5%; U. aalge DE=16%, pddepth =1%, pdagg=0.5%, pddepth* pdagg =2%). (C & D) Number of dives (A. torda DE=11%, pddepth =6%, pdagg =8%, pddepth * pdagg =21%; U. aalge DE=19%, pddepth =10%, pdagg =20, pddepth * pdagg =32%). (E&F) Depth of dives (A. torda DE=11%, pddepth =6%, pdagg =8%, pddepth * pdagg =21 U. aalge DE=22%, pddepth=17%, pdagg =2%, pddepth * pdagg =29%). And (G & H) bout length (n dives; A. torda DE=17%, pddepth =2%, pdagg =7%, pddepth * pdagg =38%; U. aalge DE= 8%, pddepth =18%, pdagg =13%, pddepth * pdagg =37%). Total deviance explained (DE) and partial deviance (pd) for azimuth, see Appendix A9 for model summary and A11 for interactions.
