| Abstract | Understanding the long-term dynamics of hydrological changes in mire ecosystems is critical for predicting their responses to climate changes and managing carbon-rich peat deposits. This study reconstructs the late-Holocene hydrological dynamics of a mire at the southern boundary of the mixed forests of the East European Plain, with a focus on non-Sphagnum (consisting of wood and grass remains) peats. We apply a multiproxy approach, utilising plant macrofossil analysis, testate amoeba assemblages, and peat humification measurements as proxies of past moisture conditions. The data reveal that the main changes in vegetation cover over the last 3000 years correspond well to climatic variation. However, the agreement among the hydrological reconstructions based on three proxies was good only at the initial stage of peat accumulation and greatly reduced with the predominance of trees in vegetation cover. Moreover, our findings show that Sphagnum-dominated peats of an adjacent mire were characterised by a better agreement among hydrological proxies. Overall, despite the agreement among various proxies can vary depending on the type of peat deposits, an application of a multi-proxy approach can reveal complimentary aspects of the hydrological regime variation in mires. |
