Report on analysis of interactions among the mesopelagic community and with predators

Description and analysis of the trophic niche overlap and partition among the key species within each meso and bathypelagic communities for each case study locations where stable isotope data are availableEstimation of the annual energy and biomass removals by top predators mainly cetaceans and seabirds of major mesopelagic prey groups from the different European marine subregions The analysis will combine relative proportions and energetic densities of ingested prey as well as predator energetic requirements and population sizes
