The performance of single - and multi - proxy transfer functions ( testate amoebae ,
26 Peatlands are widely exploited archives of palaeoenvironmental change. We developed and 27 compared multiple transfer functions to infer peatland depth to the water table (DWT) and pH 28 based on testate amoeba (percentages or presence/absence), bryophyte presence/absence and 29 vascular plant presence/absence data from sub-alpine peatlands in the SE Swiss Alps in order 30 to compare the per...
متن کاملComparative ecology of vascular plant, bryophyte and testate amoeba communities in four Sphagnum peatlands along an altitudinal gradient in Switzerland
Monitoring tools are needed to assess changes in peatlandbiotic communities and ecosystem functions in response to on-going climate and other environmental changes. Although the responses of soil organisms and plants to ecological gradients and perturbations do not always correlate, peatland monitoring is mainly based on vegetation surveys. Testate amoebae, a group of protists, are important co...
متن کاملA near-annual palaeohydrological study based on testate amoebae from a sub-alpine mire: surface wetness and the role of climate during the instrumental period
We present the first testate amoeba-based palaeohydrological reconstruction from the Swiss Alps, and the first depth to the water table (DWT) calibration dataset for this region. Compared to existing models, our new calibration dataset performs well (RMSEP1⁄4 4.88), despite the length of the Faculty of Physics, Adam Mickiewicz University, Poznań, Poland water table gradient covered (53 cm). The...
متن کاملImpact of Simulated Nitrogen Pollution on Heathland Microfauna, Mesofauna and Plants. 2
S 11 Deposition of reactive nitrogen derived from intensive agriculture and industrial processes is a major 12 threat to biodiversity and ecosystem services around the world; however our knowledge of the impacts 13 of nitrogen is restricted to a very limited range of organisms. Here we examine the response of groups 14 of microfauna (testate amoebae), mesofauna (enchytraeid worms) and plants to...
متن کاملPaleohydrologic reconstruction based on n-alkane distributions in ombrotrophic peat
Proxies such as plant macrofossils, humification indices and testate amoebae have been developed to reconstruct past hydrological variability in ombrotrophic peatlands. Reconstructions based on these approaches have resulted in records of decadalto centennial-scale moisture variability in regions of North America and elsewhere. Although the various peatland moisture proxies generally show signi...
