Sequential Load Transport in Grass-Cutting Ants (Atta vollenweideri): Maximization of Plant Delivery Rate or Improved Information Transfer?

Figure 3

Distance at which first carriers in a transport chain transferred their fragments, for the three different fragment sizes assayed. Bars indicate how many loads were transferred within a distance category (bin width 2 m). Fragments were offered and collected at “0 meters,” and 100% refers to all transferred fragments of a given size. Trail length was 33 m. Transport distance for loads of different size did not differ significantly (statistics in text).
