Stepwise multiple linear regression results for temporal variation (range) in δ13C and δ15N of cladocerans, copepods and amphipods as a function of environmental parameters

MetricStandardized coefficientspr2adj.
Cladoceran δ13C0.6 TDP + 0.1 fish complexity< 0.010.50
Cladoceran δ15N-0.6 Secchi + 0.4 surface area< 0.010.47
Copepod δ13C0.6 Chl a< 0.010.31
Amphipod δ15N0.5 SRP< 0.010.24

No significant regressions (p > 0.05) were found for copepod δ15N and amphipod δ13C
