Testate amoebae allowed quantitative reconstruction of the local water table using a transfer function based on a training set from N and W Poland. Special attention is paid to the testate amoeba Arcella discoides, which responds to rapid water-table fluctuations more than to average surface wetness. Macrofossils supported by local pollen tracked the local vegetation dynamics caused by local human impact and disturbance, including nutrients. Regional pollen showed human-induced landscape change outside the bog. Tree rings of Pinus sylvestris reflected the history of tree establishment and desiccation of the bog. Strong correlations between DCA axes 1 of regional pollen, of macrofossils and of testate amoebae, and a testate-amoebae-based water-table reconstruction that excludes A. discoides, indicate that changes on all spatial scales are linked, which is explained by a strong hydrologic connection between bog and surroundings. The combination of proxies shows that groundwater levels were modified by both human impact and climate change. STUDY NOTES: Depth to Water Table (DWT) reconstruction for Slowinskie Bog, Poland, based on Testate Amoeba. Slowinskie Bog is located in northern Poland, ~10km from the Baltic shoreline. All calculations are based on percentage of each species of Testate Amoeba in a sample (See Booth et al., 2010). Age model is from (Lamentowicz et al., 2009). Depth to Water Table (DWT) is dependent on vegetation season temperature and summer water deficit, providing a mixed temperature and precipitation signal.
