Abstract Background In marine pelagic ecosystems, the spatial distribution of biomass is heterogeneous and dynamic. At large scales, physical processes are the main driving forces of biomass distribution. At fine scales, both biotic and abiotic param

International audience; Few studies have examined the foraging ecology of top marine predators by taking into account the vertical and horizontal dimensions simultaneously. In this study, using 3-dimensional reconstruction of underwater animal paths,

Summary 1. Optimal diving models have been developed to investigate how air-breathing predators should adjust their diving behaviour to optimize their foraging efficiency. Using time-depth recorders and 3D accelerometers, we addressed this question o

International audience; Understanding the diving behaviour of diving predators in relation to concomitant prey distributioncould have major practical applications in conservation biology by allowing theassessment of how changes in fine scale prey dis
