Figures & data
Figure 1 Isotopic enrichment (mean ± SD) in soil arthropods from a Westland petrel colony. Animals were collected from within burrows unless noted. Burrow and forest floor data for the Talitridae, as known leaf litter detritivores, are shown combined. The number of animals and analysis replicates for each taxon is given by n and r; unreplicated taxa have no values shown. One soil sample was analysed per burrow; guano data came from a single pooled sample. The error bars for burrow Leiodidae do not include the outlier. Key: Acari, grey triangles; Arachnida, black triangles; Chilopoda, crosses; Diplopoda, open circles; Diplura, open triangle; Isopoda, grey circle; Talitridae, grey square; Coleoptera (various), diamonds; Leiodidae (Coleoptera), grey diamonds; Lepidoptera, black square; Formicidae, open squares. Filled labels indicate marine C consumers; soil and guano isotopic end-members are shown by the large symbols.
