We reconstructed the Holocene developmental history of a kettle-hole peatland in the Tuchola Forest of Northern Poland, using pollen, testat amoebae and plant macrofossil indicators. Our aims were to determine the timing and pattern of autogenic succession and natural and anthropogenic influences on the peatland. Northern Poland is under mixed oceanic and continental climatic influences but has...

Palaeoecological evidence for anthropogenic acidification of a kettle-hole peatland in northern Poland

Lamentowicz, Mariucz ; Tobolski, Kazimierz ; Mitchell, Edward A. D.

In: The Holocene, 2007, vol. 17, no. 8, p. 1185-1196

The Holocene developmental history of a small kettle-hole peatland in northern Poland was studied using radiocarbon dating and analyses of pollen, plant macrofossils and testate amoebae with the aim of sorting out the influences of climate change, autogenic succession and human impact. The mire followed the classical succession from lake to a Sphagnum-dominated peatland, but peat...

The palaeoecological history of the Praz-Rodet bog (Swiss Jura) based on pollen, plant macrofossils and testate amoebae (Protozoa)

In: The Holocene, 2001, vol. 11, no. 1, p. 65-80

Stratigraphy, radiocarbon dating and analyses of pollen, plant macrofossils and testate amoebae were used to reconstruct the development and ecology of a small raised bog in a karst-dominated landscape in the Swiss Jura Mountains. Special focus was on past vegetation and on the history of Pinus rotundata in relation to anthropogenic and climatic influences. Testate amoebae were used to...

Testate amoebae (Protists) as palaeoenvironmental indicators in peatlands

Lamentowicz, Mariusz ; Mitchell, Edward A. D.

In: Proceedings of the Workshop « Reconstruction of Quaternary palaeoclimate and palaeoenvironments and their abrupt changes », 2005, vol. 16, p. 58-64

Testate amoebae (or testaceans, Testacea, Arcellaceans) are unicellular eukaryotic organisms living in freshwater or most terrestrial habitats such as soils, mosses, lakes, rivers, as well as brackish habitats such as estuaries. They are very abundant in Sphagnum mosses, where they live in the top part of mosses and the oxygenated part of the peat. The tests (shells) of Tesiacea are well...
