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.
