“…Sample pretreatment is simple for the Quadrat Leaf Count method (see Mauquoy et al, 2010/11 for detailed description). Species-level identification of a range of mosses, graminoids and dwarf shrubs is possible using reference type material (both sub-fossil and modern) and drawings, keys and plates (Grosse-Brauckmann, 1972a,b;Grosse-Brauckmann and Streitz, 1992;Katz et al, 1977;Smith, 2004;Mauquoy and van Geel, 2007). Preservation of macrofossils in blanket mires is variable, but sometimes poor, given the higher degree of water-table fluctuation and degree of humification, and slower growth rate in these ecosystems.…”

This is an author-deposited version published in : http://oatao.univ-toulouse.fr/ Eprints ID : 11364 The Netherlands a b s t r a c t Peat, especially from acidic mires (bogs), is a natural archive of past environmental change. Reconstructions of past climate from bogs commenced in the 19th Century through examination of visible peat stratigraphy, and later formed the basis for a postglacial climatic scheme widely used in Northwest Europe. Nevertheless, misconceptions as to how bogs grow led to a 50-year lacuna in peat-climate study, before the concept of 'cyclic regeneration' in bogs was refuted. In recent decades, research using proxyclimate indicators from bogs has burgeoned. A range of proxies for past hydrological change has been developed, as well as use of pollen, bog oaks and pines and other data to reconstruct past temperatures. Most of this proxy-climate research has been carried out in Northern Europe, but peat-based research in parts of Asia and North America has increased, particularly during the last decade, while research has also been conducted in Australia, New Zealand and South America. This paper reviews developments in proxy-climate reconstructions from peatlands; chronicles use of a range of palaeo-proxies such as visible peat stratigraphy, plant macrofossils, peat humification, testate amoebae and non-pollen palynomorphs; and explains the use of wiggle-match radiocarbon dating and relationship to climate shifts. It details other techniques being used increasingly, such as biomarkers, stable-isotopes, inorganic geochemistry and estimation of dust flux; and points to new proxies under development. Although explicit protocols have been developed recently for research on ombrotrophic mires, it must be recognised that not all proxies and techniques have universal applicability, owing to differences in species assemblages, mire formation, topographic controls, and geochemical characteristics.

Evolution of small valley mire in central Poland as a result of hydroclimatic oscillations

et al. 2012

This paper demonstrates the results of analyses of Cladocera, pollen, plant macrofossil, lithological and radiocarbon data recovered from a mire located in the Rawka River valley in central Poland. These studies permit to recognise the development of hydrology phases in Kopanicha mire and give insight into Holocene fluvial dynamics of the system; radiocarbon dating partly allowed dating of the patterns of Holocene valley floor development of the Rawka River. The Kopanicha mire was formed during the Atlantic period. At that time, an oxbow lake formed, becoming a mire during the Subboreal and possibly Subatlantic periods. The high sensitivity of the oxbow lakes, fens, fauna, and flora remains to climate variations -especially to changes in water level connected with the aggradation-erosion cycle of rivers -allows the reconstruction of the palaeoecological changes that occurred in the mire. The frequency and timing of hydroclimatic oscillations at Kopanicha show strong similarities to records from other sites in Poland. Changes in Cladocera frequency and plant assemblages were mostly influenced by the Rawka River which controlled the hydrological regime of the mire. The main factors controlling the presence of Cladocera taxa were the water level and the presence of favourable conditions in the mire (e.g. pH, vegetation). Most of the changes occurred in response to climate changes, but some of them were connected with local factors.

Multiproxy study of anthropogenic and climatic changes in the last two millennia from a small mire in central Poland

et al. 2009

The _ Zabieniec kettle hole is the first peatland in central Poland analyzed quantitatively with four biotic proxies (plant macrofossils, pollen, testate amoebae and chironomids) to reconstruct the past environmental change. Palaeoecological data were supported by historical and archaeological records. We focused on autogenic vegetation change and human impact in relation to climatic effects. The aims of our study were (a) to describe the development history of the mire during the last 2,000 years, (b) to date and reconstruct the anthropogenic land-use changes and (c) to discuss a possible climatic signal in the peat archive. The combination of proxies revealed dramatic shifts that took place in the peatland since the Roman Period.
