Individual characteristics can, indeed, play an important role in establishing group dynamics. The central question we address is whether or not aggregation influences predator prey relationships. To answer this question, we analyse the consequences of schooling when estimating functional response in four configurations: (1) no schooling of either prey nor predators; (2) schooling of prey only; (3) schooling of predators only; and (4) schooling of both prey and predators. Aggregation is modelled using the rules of attraction, alignment and repulsion. We find important differences between the various configurations, highlighting that functional response is largely affected by collective behaviour. In particular, we show: (1) an increased predation efficiency when prey school and (2) different functional response shapes: Holling type II emerges if prey do not school, while Hailing type III emerges when prey aggregate. specialized 036 020 134 232-243 2015 0079-6611 https://www.documentation.ird.fr/hor/fdi:010064757 10.1016/j.pocean.2015.02.002 0079-6611 [F B010064757] https://www.documentation.ird.fr/hor/fdi:010064757 https://www.documentation.ird.fr/intranet/publi/2015/07/010064757.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2015-07-29 2017-08-23 fdi:010064757 fre
