  abstract = {{W}e present predator-prey models taking into account the individual behaviors of prey individuals and predators, which can use either grouped or solitary strategies. {W}hen prey individuals are grouped, they face less predation but have less access to the resource, which is shared with other individuals of the group. {G}roups of predators are more efficient to capture a prey than solitary ones. {H}owever, predators in groups must share captured prey with predators of their group. {W}e study two models which differ in the way encounter rates are calculated. {W}e present the effects of the different behavioral strategies on the overall dynamics of the predator-prey model. {N}ext, we couple the fast theoretical game dynamics to a slow population dynamics model. {W}e use aggregation methods to obtain the aggregated model. {S}uch a model allow us to study the effects of the strategies selected by prey individuals and predators on the stability of the prey-predator system. {U}nder some conditions, we show that, when aggregating, lonely preys can exclude cooperative predators. {W}e also show how predators can coexist against aggregative preys, when changing strategy from solitary to cooperative.
