Fig. 4 : Biomass and trophic position of canopy arthropod taxa in different land-use systems (Rainforest, Jungle rubber, Rubber and Oil palm) in the landscapes Bukit Duabelas (left column) and Harapan (right column). The dot plots show mean (± SD) Δ13C and Δ15N values of arthropod taxa (n = 4 plots * 2 seasons = 8 per taxon per landscape), with the size of dots representing their mean biomass. The light blue diamond and horizontal line, and the red diamond and vertical line represent the biomass-weighted mean and range of arthropod Δ13C and Δ15N values, respectively. The bar plots show mean (± SEM) biomass (mg/m²) of arthropods grouped into Δ15N classes as an indication of trophic level (turquoise - algae-microbivores, green – herbivores, red – predators, striped – omnivores); note the different scales for biomass.
