Compared \nto existing models, our new calibration dataset performs well \n(RMSEP=4.88), despite the length of the water table gradient \ncovered (53 cm). The present-day topography and vegetation \nof the study mire Mauntschas suggest that it is partly ombrotrophic \n(large Sphagnum fuscum hummocks, one of which was the coring site) \nbut mostly under the minerotrophic influence of springs in the mire \nand runoff from the surrounding area. Ombrotrophic Sphagnum fuscum \nhummocks developed at the sampling site only during the last 50 \nyears, when testate amoebae indicate a shift towards dry and/or \nacid conditions. Prior to AD 1950 the water table was much higher, \nsuggesting that the influence of the mineral-rich water prevented \nthe development of ombrotrophic hummocks. The reconstructed DWT \ncorrelated with Pinus cembra pollen accumulation rates, suggesting \nthat testate amoebae living on the mire and P. cembra growing \noutside of it partly respond to the same factor(s). Finally, \ntemperature trends from the nearby meteorological station \nparalleled trends in reconstructed DWT. However, contrary \nto other studies made on raised bogs of northwestern Europe, \nthe highest correlation was observed for winter temperature, \ndespite the fact that testate amoebae would more logically \nrespond to moisture conditions during the growing season. \nThe observed correlation with winter temperature might reflect \na control of winter severity on surface moisture during at least \nthe first part of the growing season, through snow melt and soil \nfrost phenomena influencing run-off. More ecohydrological work \non subalpine mires is needed to understand the relationships \nbetween climate, testate amoebae and peatland development.\n","author":null,"citation":"Lamentowicz, M., W.
