Correlations between (a) δ¹³C and Δ¹⁴C and (b) δ¹⁵N and Δ¹⁴C for all collembolan species combined, between (c) δ¹³C and Δ¹⁴C and (d) δ¹⁵N and Δ¹⁴C for the epigeic collembolan species (i.e. L-layer inhabitants), between (e) δ¹³C and Δ¹⁴C and (f) δ¹⁵N and Δ¹⁴C for the edaphic collembolan species (i.e. FH-layer inhabitants), and between (g) δ¹³C and Δ¹⁴C and (h) δ¹⁵N and Δ¹⁴C for all taxa combined. Abbreviations for collembolan species are shown in table 1. Solid lines show significant relationships (p < 0.05), while a dashed line shows a marginally significant relationship (p < 0.1) between variables. Shaded areas represent 95% confidence intervals.
