Figure 4.

Box plots of carbon (A) and nitrogen (B) contents, C/N ratio (C) of fish muscles, periphyton within their territories, benthic animals, detritus, sediments, and particulate organic matter (POM) in water column. Red boxes and red letters indicate values and statistical result of periphyton. Shared letters on boxes indicate no significant differences, and pairs that do not share any letters in common were significantly different by the Tukey’s post hoc test between fish species. Species abbreviations are shown in Table 1. *denotes non-cichlid fish.
