Table 2

GLMs of square root, log-transformed detection time of each moth attacked, for each species and tree rotation with three main effects (absolute moth orientation, human subject and tree) and all pairwise interactions. Test statistics reported for the GLM are: FS (d.f.), significance (***p<0.001, **p<0.005, *p<0.05, p>0.05=n.s.).
