Are nested networks more robust to disturbance? A test using epiphyte-tree, comensalistic networks.

After accounting for the effect of network size on N (type-2 regression: N = 0.59+0.077*logSize, F 1,57 = 9.98, P<0.0025), differences between network types were highly significant (F 2,56 = 8.21, P<0.0007) and pair-wise comparisons discriminated comensalistic networks from antagonistic and mutualistic ones (Scheffé-test: P<0.0009 and P<0.029, respectively), which differed marginally between themselves (P>0.052).
