“…Palaeoecological studies may contribute to unravel this complex contribute to unravel the complex polygon mires (De Klerk et al ., ). In order to arrive at the most detailed reconstruction of past habitat conditions and environmental processes, it is desirable to follow a multi‐proxy approach (Blundell and Barber, ; Magyari et al ., ; Swindles et al ., ). This paper compares various proxies with respect to their accuracy and resolution in reconstructing past moisture conditions in a NE Siberian ice‐wedge polygon peatland.…”

Ice-wedge polygon mires feature a micro-relief of dry ridges, shallow wet depressions, deeper wet troughs and transitional sites, resulting in a local mosaic of vegetation. The correct recognition of these landscape elements in palaeoecological studies of peat sections requires insight about the suitability of proxies and their potential for palaeoecological reconstruction in order to reconstruct vegetation and wetness patterns as well as dynamics. This paper analyses a 105.5 cm long peat section with a base dating to about 4000 cal yr BP from an ice-wedge polygon mire near Kytalyk (NE Siberia). Pollen, macrofossils, testate amoebae, geochemistry and sediment properties were analysed in order to compare the suitability of these proxies to reconstruct past surface wetness. The proxies show similar wetness trends. Pollen and geochemistry data did not always permit wetness reconstruction, the former because many pollen types do not allow the identification of taxa at a low taxonomic resolution, the latter because later taphonomic processes modify chemical variables in deeper peat layers. Macrofossils provided the most detailed wetness reconstruction, because they could be identified to genera or species, for which the moisture requirements are accurately known from their present-day distribution in ice-wedge polygons. All proxies, except geochemistry, show an obvious change from wet to dry conditions at around 20 cm depth. However, as the proxies sometimes show contradictory results, a multi-proxy approach is preferable over a single proxy interpretation as it allows the reconstruction of environmental development in a broader palaeoecological context.

“…Ombrotrophic peatland development was substantially affected by climate changes in the Holocene (Barber et al, 2004;Gałka et al, 2015Gałka et al, , 2016Lamentowicz et al, 2015;Mauquoy and Barber, 1999;Tuittila et al, 2007;Van der Linden and Van Geel, 2006). Furthermore, disturbances due to human activities increased in the past several centuries, which led to a huge deposition of minerals and nitrogen on peatland surfaces (Dudová et al, 2012;Ireland et al, 2014;McClymont et al, 2008;Swindles et al, 2015). This led to a decline in the Sphagnum peat-forming species (Hughes et al, 2008).…”

This study explores the history of the development of Sphagnum communities in an ombrotrophic peatland -Bagno Kusowo -over the past 650 years, based on high-resolution plant macrofossil and testate amoebae analysis. Our research provided information related to the length of peatland existence and the characteristics of its natural/pristine state before the most recent human impacts. Changes in the Sphagnum communities before human impact could have resulted from climate cooling during the 'Little Ice Age' (LIA). In this cold and unstable hydrological period, among vascular plants, Eriophorum vaginatum and Baeothryon caespitosum dominated in the peatland vegetation. Peat-forming Sphagnum communities survived the drainage conducted during the 20th century at the Bagno Kusowo bog. We provide three important messages through this study: (1) testate amoebae reflect similar hydrological trends in two peat cores despite considerable microhabitat variability, (2) average long-term water level 10 cm below the surface should be a target for active bog conservation and (3) sites like Bagno Kusowo are extremely important to preserve the remains of pristine biodiversity (including genetic diversity of plants and protists) that was completely removed from most of the raised bogs in Europe due to human activities, for example, drainage.
