Hide and seek in the Bay of Biscaya functional investigation of marine megafauna and small pelagic fish interactions ArchiMer

Prey and predator distributions influence one another. Understanding the scale and the orientation of predator-prey spatial correlations is crucial in foraging ecology. Growing evidence suggests that predator-prey interactions are more constrained by functional characteristics of both the predator and the prey. Unfortunately, in marine pelagic systems, the scale and orientation of spatial correlations between predators and prey have been only little explored from a functional point of view. We tested the existence of fine-scale association between predators and fish functional groups. Visual predator sightings and acoustic fish records were collected synchronously during oceanographic surveys from 2004 to 2014. Prey biomass was integrated by nautical miles...
