Table 1.

Results of a three-way ANOVA to test for the effect of the travel direction (ants travelling from the bridge ends towards the centre of the bridge vs those travelling from the centre towards the bridge ends),the bridge side (nest vs source) and the sector (bottleneck vs entrance) on the time required to cross a sector by an ant

As ants were individually followed across the two sectors, the sector effect was treated as a repeated measure factor. The data were log-transformed to allow for normality.
