Mean percentage of total colony workers in nests of each quality over time for (a) control; (b) nest predation, (c) peripheral predation groups, and (d) when the original nest was destroyed (from previously published data).

<p>The mean represents n = 10 colonies for each time point in (a)–(c) and n = 11 colonies in (d). Error bars indicate 95% confidence intervals.</p

Cross tabulation for effect of manipulation on final nest choice.

<p>Best choice: chose the better new nest, or split between the two new nests; moderate: chose the worse new nest; impaired: remained in starting nest or split between starting and worse new nests (nest destruction from previously published data).</p><p>Cross tabulation for effect of manipulation on final nest choice.</p

The range of nest types used in the experiment: (a) clear cover, 1mm wall height, 4mm entrance width; (b) red filter cover, 2mm wall height, 4mm entrance width; (c) red filter cover, 2mm wall height, 1mm entrance width; (d) clear cover, 1mm wall height, 4mm entrance width, acetate film with holes for ant removal and second acetate layer to act as a cover; (e) clear cover, 1.8mm wall height, 4mm entrance width; (f) red filter cover, 1.8mm wall height, 2mm entrance width. (g) Experimental arena, starting nests were of poor quality and were not destroyed, allowing voluntary emigrations to occur.

<p>A similar arena was used for the nest destruction treatment, measuring 800x165mm [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0141012#pone.0141012.ref015" target="_blank">15</a>].</p
