The commonly used technique for determination of plant stable carbon isotope composition is analysis of CO 2 liberated during combustion of chemically extracted nitrocellulose or ␣-cellulose. The ␦ 13 C of cellulose is usually accepted as a more reliable record of growth environment conditions compared with bulk plant material analysis. Unfortunately, cellulose extraction techniques are time-consuming, and usually require toxic chemicals such as toluene, chloroform, benzene, methanol, concentrated acids, etc. We tested the possibility of replacing nitrocellulose analysis with bulk organic analysis. Sphagnum and Polytrichum mosses collected along a vertical transect (altitudes 500 to 1400 m), provided material for analysis in the wide range of ␦ 13 C: Ϫ32.66‰ and Ϫ26.20‰ for bulk organic matter and Ϫ24.11‰ and Ϫ31.86‰ for nitrocellulose. The correlation for ␦ 13 C value of extracted cellulose and ␦ 13 C values of bulk organic matter were very good (Ͼ0.95). Our results suggested that ␦ 13 C analyses can be performed on bulk plant material instead of cellulose, without significant loss of information, at least for Polytrichum and Sphagnum mosses. Moreover, we confirmed that the extraction process of nitrocellulose did not cause any significant isotopic fractionation. (J Am Soc Mass

“…When the Sphagnum plant is more saturated the water film over the photosynthetic cells impedes the incorporation of CO 2 and so the plant becomes less selective against 13 C (Williams and Flannagan, 1996). Because of these competing influences, and the possible influence of other factors like temperature (Skrzypek et al, 2007), d 13 C records derived from peat sequences must be evaluated carefully (Markel et al, 2010), and in the context of other reconstructed parameters.…”

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.

“…Huang et al (2013) proposed that the climatic significance of d 13 C values in peat bogs may vary from region to region, and that independent studies of modern processes are required to properly ascertain the relationship between d 13 C TOC values and climate factors in a certain location. Various factors can influence the d 13 C value of plant tissue, but in certain ecosystems and locations many of these factors are nearly constant or their differences are negligible (Skrzypek et al, 2007a(Skrzypek et al, , 2010, and precipitation and temperature are considered the main controlling factors (Menot and Burns, 2001;Skrzypek et al, 2007bSkrzypek et al, , 2011Loisel et al, 2009;Tillman et al, 2010;Holzkämper et al, 2012). Wang et al (2013) reported a strong relationship between mean annual temperature and d 13 C values in C3 plants sampled from the 400 mm mean annual precipitation isoline in north China.…”

“…Wang et al (2013) reported a strong relationship between mean annual temperature and d 13 C values in C3 plants sampled from the 400 mm mean annual precipitation isoline in north China. Indeed, many studies have reported that temperature is the main factor affecting the carbon isotopic composition of peat plants (Skrzypek et al, 2007b(Skrzypek et al, , 2011Tillman et al, 2010;Holzkämper et al, 2012;Huang, 2015). Accordingly, d 13 C time series data from the Altay peat core, north Xinjiang, are thought to provide a continuous proxy record of surface air temperature since 11.5 ka BP (Huang, 2015).…”
