Pearson r correlationsa between organic matter pools, or the phytoplankton: bacterioplankton biomass ratio, and the allochthony in different zooplankton groups in the lake Övre Björntjärn, sampled during different parts of the year.

Values in brackets show the possible range of correlation coefficients obtained for different allochthony scenarios. The biomass ratio is log-transformed because of strong (>2) skewness.aSignificance: not significant (denoted n.s.);p (*));p Pearson r correlationsa between organic matter pools, or the phytoplankton: bacterioplankton biomass ratio, and the allochthony in different zooplankton groups in the lake Övre Björntjärn, sampled during different parts of the year.
