Table 1. Summary of % contribution based on abundances of food items (e.g. functional groups) found in stomachs of 120 D. monticola in three standard length size classes categories

Figure 2. Results of the NMDS (stress 20.7%). Small-size = individuals between 20 and 59 mm in SL, medium-size = individuals between 60 and 100 mm SL and large-size = individuals larger than 100 mm Sl. Labels depict the 14 functional groups in which food items were clustered

Table 2. Results of the indicator species analysis for the three size class categories. Small-size = 20–59 mm SL; medium-size = 60–100 mm SL; larger-size = < 100 mm SL. Significance values determined based on 1000 permutations. Statistically significant prey items (<0.05) are bolded. Note that indicators values below 0.5 are considered as poor indicators (Punchi-Manage et al. 2013)
