In the European Arctic, combined evidence from oxygen isotope and pollen-inferred precipitation records, cladoceran-inferred lake levels, diatom-inferred lake-water ionic strength, and elemental flux records of erosion intensity into lakes, all suggest more oceanic conditions in the region during the early part of the Holocene than today, with a shift towards drier conditions between approximately 6,000 and 4,500 years BP [34].

-
The very dry period corresponding to shifts from birch to pine corresponds to increasing frequency of diatom and cladoceran taxa indicating lake-level reduction and vegetation overgrowth of numerous lakes [43].

Likewise, diatom and cladoceran evidence suggest dry warm summers during the period dominated by pine (~7,000 – 3,500 years BP).

For example, in the freshwater cladoceran Daphnia spp., growth rates are correlated with the concentration of eicosapentaenoic acid in the water column [43].

Under high P: Si ratios, the increased time between phytoplankton and cladoceran peaks opened a loophole for filamentous cyanobacteria (Oscillatoriales) in warm years to establish dominance after the diatoms, which are silicate limited.
