Richardson, Gustavo Q. Romero, Martin Videla, and Diane S. Srivastava. 2015. Dominant predators mediate the impact of habitat size on trophic structure in bromeliad invertebrate communities. Ecology 96:428–439. http://dx.doi.org/10.1890/14-0304.1
Appendix A. Figuresand tables showing the absolute biomass of organisms, the effect of latitudinal location, the relative biomass of predator species, habitat complexity, listing all species and statistical results.
Fig. A1. Total biomass (log-transformed, in mg) of predators, detritivores, and resources along the habitat size gradient (log-transformed bromeliad volume in l) for (A) sites without and (B) sites with odonates in the regional species pool. Predator biomass is depicted by open symbols and dashed lines (significantly different slopes = 0.17 ± 0.09 and 0.78 ± 0.11 for sites without and with odonates, respectively. See Table S1 for statistical analysis.), detritivore biomass by gray-filled symbols and medium solid lines (slopes = 0.81 ± 0.05 and 0.26 ± 0.09) and resource biomass by black-filled symbols and thick solid lines (slopes = 0.75 ± 0.07 and 0.71 ± 0.06).
Fig. A2. The latitudinal location of the sites and predator–detritivore biomass ratios in bromeliads at these sites. Data points represent individual bromeliads and are jittered along the x-axis for illustrative purposes.
Fig. A3. Odonate presence in individual bromeliads along the habitat size gradient (log-transformed bromeliad volume in l) for those sites with odonates in the regional pool. Data points are jittered along the y-axis for illustrative purposes. The relationship was fitted using a generalized linear model with binomial errors.
Fig. A4. Relative biomass for the different predator species, ranked by highest relative abundance per site. Relative biomass refers to the predator level only and was calculated per bromeliad, data were then averaged across bromeliads and years per site. Odonate species are shown in red. The species labels refer to the "working IDs" in Table A1. The Picinguaba site is not shown because it lacks species-specific biomass data (analyses for this small data set are based on species presence/absence and pooled biomass measurements at each trophic level).
Fig. A5. Habitat complexity in the bromeliad decreases with increasing habitat size (log-transformed bromeliad volume in l). Complexity is calculated as log10(number of green leaves/bromeliad volume).
Table A1. List of invertebrate species present in the bromeliads at our sites based on the surveys in this study. Many species were identified to species level but were distinguished using morphological characters and were assigned a unique "Working ID" (except for species in the small data set from the Picinguaba site). The morphological and molecular identification of those species is ongoing. Species were assigned to one of two trophic levels: P = Predator, D = Detritivore.

Table A2. Results of the linear mixed effects model analysis testing main effects and two-way interactions on the absolute biomass of resources, detritivores and predators in each bromeliad (all log-transformed) with "site" as a random effect. Habitat size = log-transformed bromeliad volume [mL], df= degrees of freedom (numerator df, denominator df). P values <0.05 printed in bold.

Table A3. Results of the linear mixed effects model analysis testing main effects and two-way interactions on biomass ratios (log-transformed) with "site" as a random effect. Here, we test the effect of tabanid presence in the regional pool instead of odonate presence. Habitat size = log-transformed bromeliad volume [mL], df= degrees of freedom (numerator df, denominator df). P values <0.05 printed in bold.
