Variation in trophic cascade strength is triggered by top-down process in an ant-wasp-fig system

R code and Original data for:Figure 2: Number of wasps from branches with weaver ants or without ants in the cool-dry (A), hot-dry (B), and rainy (C) seasons. Species composition is shown on the top of bar plot for each season, left pie (with ants), right pie (ants excluded). Syconia in the cool-dry season in ant exclusion treatments were all aborted. Linear mixed-effects models were fitted, with the number of fig wasps as the response variable, with treatment (trees with or without Oecophylla smaragdina ) as the fixed factor, tree as a random factor. * (P < 0.05), ** (P < 0.01), *** (P < 0.001), NS = not significant. CF = Ceratosolen fusciceps; SM = Sycophaga mayri; ST = S. testacea; SA = S. agraensis; AS = Apocrypta sp.; AW = A. westwoodi. Columns and bars show mean ± SD. # represent pollinating fig wasp. Numbers under the pie represent replications of syconium sampled.Figure 3: Number of seed from branches with weaver ants or ants excluded in cool-dry, hot-dry, and rainy seasons. * (P < 0.05), *** (P < 0.001). Numbers in the box represent replications of syconium sampled.Figure 4: Mean (±SD) interaction strength (A) of weaver ant, Oecophyla smaragdina, on the gall making fig wasp, Sycophagus mayri, and the strength of the trophic cascade (B) in different seasons. * (P < 0.05), *** (P < 0.001). Numbers in the brackets represent replications of with ants/ant exclusion branchlets pairs.Figure 5: Box plot of the number of weaver ant nests (A), number of weaver ants foraging in fig-bearing branchlets (B), foundress number (C), and oviposition scars of non-pollinating fig wasps (D) in the fruits of Ficus racemosa after receptive stage of Ficus racemosa in different seasons. Different letters represent significant differences between each season, pairwise comparisons conducted using Tukey and Kramer test. Each circle represents a data point. Figure 6: Number (mean ± SD) of weaver ants, Oecophyla smaragdina (A), pollinating fig wasp activity, Ceratosolen fusciceps (B), and gall making fig wasp, Sycophagus mayri activity (C) from 6:00 to 20:00 in different seasons. Symbols represent means and drop lines show the standard deviation. Different letters represent significant differences between each season, significance derived using nonparametric rank-based analysis of longitudinal data with ANOVA-type statistics (ATS).
