Figure 1
δ15N and δ13C values of juvenile A. ceropegia in the feeding experiment.
With stable isotope Bayesian ellipses (solid line) and convex hull (dotted line) for each group. Resources (birch pollen and fruit flies) are depicted as circles, spiders fed with pollen and fruit flies as triangles and spiders only fed with fruit flies as squares.
