<p>Transport duration (d), number of carriers involved (n) and the waiting times (w) between transport events are plotted as a function of time (t). <b>(A)</b> Time needed for a pellet to be sequentially carried over a distance of 2 m from the excavation site. Solid lines show the results of regression with ln-transformed d-values on both days (first day: d = 0.6·e<sup>−0.3·t</sup>, <i>r</i><sup>2</sup> = 0.45, <i>N</i> = 60, <i>P</i><0.001; second day: d = 0.4·e<sup>−0.04·t</sup>, <i>r</i><sup>2</sup> = 0.05, <i>N</i> = 73, <i>P</i> = 0.047). <b>(B)</b> The number of workers involved in the transport of single pellets. Solid lines show the results of regression with ln-transformed Y-values on both days (first day: n = 6.6·e<sup>−0.1·t</sup>, <i>r</i><sup>2</sup> = 0.25, <i>N</i> = 60, <i>P</i><0.001; second day: n = 7.9·e<sup>−0.03·t</sup>, <i>r</i><sup>2</sup> = 0.06, <i>N</i> = 73, <i>P</i> = 0.039). <b>(C)</b> Time a pellet remained on the floor between two transport events. Solid lines show the results of regression with ln-transformed Y-values on both days (first day: w = 3.8·e<sup>−0.2·t</sup>, <i>r</i><sup>2</sup> = 0.10, <i>N</i> = 225, <i>P</i><0.001; second day: w = 5.5·e<sup>−0.1·t</sup>, <i>r</i><sup>2</sup> = 0.02, <i>N</i> = 177, NS).</p>
