We present previously undescribed spatial group patterns that emerge in a one-dimensional
hyperbolic model for animal group formation and movement. The patterns result from the
assumption that the interactions governing movement depend not only on distance between
conspecifics, but also on how individuals receive information about their neighbors and the
amount of information received. Some of these patterns are classical, such as stationary
pulses, traveling waves, ripples, or traveling trains. However, most of the patterns have not …
We present previously undescribed spatial group patterns that emerge in a one-dimensional hyperbolic model for animal group formation and movement. The patterns result from the assumption that the interactions governing movement depend not only on distance between conspecifics, but also on how individuals receive information about their neighbors and the amount of information received. Some of these patterns are classical, such as stationary pulses, traveling waves, ripples, or traveling trains. However, most of the patterns have not been reported previously. We call these patterns zigzag pulses, semizigzag pulses, breathers, traveling breathers, and feathers.
