Table 2. Bayesian Information Criterion (BIC) of the full models with four different random effects for each food-web descriptor.

		Random effects
Models	Vegetation type	Locality	Locality/Vegetation type	Bromeliad species
Shannon-Weaver’s index	21.87	21.83	25.79	31.69
Simpson’s index	−314.16	−310.39	−308.73	−310.19
Connectance	−1102.57	−1090.4	−1097.89	−1108.65
Linkage density	−584.88	−586.99	−582.41	−564.51
Nestedness	−544.09	−546.25	−541.21	−527.14

The random effect ‘Locality/Vegetation type’ means that the vegetation types are nested within the localities. Bold characters highlight the lowest BICs.
