We introduced the gregarious instinct by means of a novel strategy that considers the average effect of the attractive forces between individuals within a given population. We watched how pattern formation can be explained by effect of aggregation depending on conditions on food and / or mortality. We propose a model that describes the corresponding dynamicand by a linear stability analysis of homogeneous solutionsidentify and interpret the region of parameters where these patternsare stable. Then we test numerically these preliminary results and findstable patterns as solutions. Finally, we developed a simplified modelallowed us to understand in greater detail the processes involved.
