Most studies on community ecology have focused on single interaction types (i.e., antagonistic, mutualistic, or competitive). On the other hand, the bulk of behavioral studies have considered interactions among individuals within the same species (i.e., group behavior or group size). To improve our understanding of community structure, I propose to investigate the interdependence between group behavior and the structure of ecological networks integrating multiple interaction types. First, I will introduce behavioral strategies among species within the framework of gametheoretic models. Second, I will complement existing database on food webs by introducing species group size and di_erent interaction types. Third, I will use this enlarged database to test alternative behavioral models of network built up to determine mechanisms generating the structure of ecological networks. This research should provide a first step toward understanding the role of group behavior in the structure of ecological networks with multiple interaction types. The relevance of this work relies on the integration of behavioral and community ecology.
