Schematic for individual-based stigmergy model.
As hosts (solid circles) walk randomly through space they deposit scent marks (open circles); note the green vs. blue scent marks for each host. If infected, the hosts simultaneously leave pathogens in the environment. t0: focal individual (blue) can move to one of eight neighboring cells or remain within its current cell. t1: In the case of encountering a conspecific cue (open green circle), the host has some probability of constraining its next step to 45 degrees on either side of the prior direction of movement (indicated by the directions of the red arrows); this probability depends on the strength of the conspecific cue that the host encounters. t2: avoiding conspecific stigmergy cues results in dynamic home range formation, but also potential pathogen exposure.
