Model description. (a) A schematic of agent movement in the model. Agents can make foraging movements (mF) within a radius r from their home (ph) to a new patch (pj) or residential movements (mR) to a new home (ph′). (b) An illustration of the variations in resource environments modulated by the parameter β. A low value of β results in a rich (dark-green patches) and heterogeneous environment (left), whereas a very high value of β results in a scarce (yellow patches) and homogeneous environment (right). When food depletes within an agent’s radius (yellow patches), it moves its residence (a → b). Otherwise, it continues to forage within its radius (c ↔ d).
