“…It is no easy task to distinguish ecological significance and statistical artifact when interpreting relationships between growth and climate in previous years, and this difficulty likely explains the lack in interpretation of the association between tree growth and temperature of the preceding year in previous studies (cf. Girardin et al, 2005;Tardif et al, 2008). Some researchers have suggested that the negative association with previous summer temperatures was related to moisture stress and found a positive correlation with previous June precipitation to support this hypothesis (Hofgaard et al, 1999;Huang et al, 2009).…”

ABSTRACT. The effects of climate on radial growth of Larix laricina (Du Roi) K. Koch, Picea glauca (Moench) Voss, and Picea mariana (Mill) BSP were investigated in the Hudson Bay Lowlands of northern Manitoba. The objective was to characterize spatial and temporal variations in growth of trees across the forest-tundra ecotone. Along a 250 km transect, 299 trees were sampled in three zones: northern forest, central tundra, and southern forest. Ring-width indices were compared with climate through correlation-and response-function analyses. Numerous years of suppressed growth at the three locales resulted from cooling that followed major volcanic eruptions at much lower latitudes. Temperatures during July of the current year and autumn of the previous year were most limiting, particularly for L. laricina, which was temperature-sensitive across the region. A weakened growth response to temperature during the 1940-60 period was likely due to atmospheric circulation shifts. Most chronologies were intercorrelated, which suggests common environmental forcing, though environmental influences differed in the southern forest (particularly for P. mariana). The source of this disparity has yet to be determined.

“…Because annual variations in photosynthetic conditions are reflected in the carbon isotope composition of tree rings (Wilson and Grinsted 1977), the use of stable carbon isotope analysis (d 13 C) of tree rings to evaluate plantenvironment interactions and plant responses to environmental change has been rapidly expanding (Joshua and Evans 1999;Liu et al 2004;Tardif et al 2008). Interannual tree-ring d 13 C variations have been found to correlate with tree species and a wide range of environmental variables such as carbon dioxide concentration in the air, light availability (Francey and Farquhar 1982;Berry et al 1997), soil water conditions (Sheu et al 1996), humidity (Hemming et al 1998;Crockett et al 2010), cloud cover (Ramesh et al 1986), temperature (Anderson et al 1998), precipitation (Fichtler et al 2010), drought and moisture stress (Leavitt 1989;Newberry 2010) and other environmental factors (Adams and Grierson 2001;McCarroll et al 2009;Savard 2010).…”

Chinese pine (Pinus tabulaeformis) trees were sampled in the Helan Mountain, northwest China. The stable carbon isotope (delta(13)C) values of whole wood, holocellulose and alpha-cellulose in tree rings over 30 years (1968-1997) were measured to study the delta(13)C response of different tree-ring components to past environmental change. There were obvious differences in the delta(13)C values of the three components. The Pearson correlation coefficient between the delta(13)C of alpha-cellulose and that of holocellulose was 0.547 (rho < 0.01); between alpha-cellulose and whole wood, the coefficient was -0.126 (rho > 0.10); between holocellulose and whole wood, the coefficient was -0.056. Correlation function analyses indicated that the delta(13)C content of tree-ring alpha-cellulose correlated strongly with the average temperature from June to August (r = 0.427, rho < 0.05), more than that of holocellulose (0.324, rho < 0.10) or total wood (-0.245, rho > 0.10). Significant correlations were observed between delta(13)C of tree-ring alpha-cellulose and the precipitation from the current year's February to July (r = -0.514, rho < 0.01) that were much higher than that of holocellulose (-0.481, rho < 0.05) or total wood (-0.249, rho > 0.10). A significant correlation (-0.545, rho < 0.01) was also found between the ring width and the delta(13)C residual chronologies. These results suggest that more past environmental information is retained in the delta(13)C of tree-ring alpha-cellulose. Thus, the delta(13)C of alpha-cellulose of tree rings is the most suitable among the studied parameters for reconstructing the past climatic conditions during the growing season. The delta(13)C values of other organic compounds in Pinus tabulaeformis xylem were affected by the external environment after carbon was fixed from the atmosphere

of climate signal in carbon and oxygen isotope records and ring width from Scots pine (Pinus sylvestris L.) in Finland.ABSTRACT: Four hundred year long records of carbon and oxygen stable isotope ratios and ring width were measured from Scots pine (Pinus sylvestris L.) from sites in Northern and Eastern Finland. Responses of isotope ratios to temperature and precipitation were analysed for the 20th century. Carbon isotope ratios responded strongly to summer temperature at both sites, whereas an influence of precipitation on the record was observed only at the site in Eastern Finland. Oxygen isotope ratios were less responsive to climatic variation than carbon at the high-frequency level. To shed light on the role of the possible divergence problem during last decades the climate responses were studied separately in the first and in the second half of the 20th century. The responses to temperature were stable in the north but in Eastern Finland the significant period of summer occurred earlier during the later half of the century. Relationships between records were studied during the 400 a period. All proxies correlated positively with each other, although temporal changes occurred. Common forcing, discovered in Northern Finland between carbon isotope and ring width records, was weaker in the earlier period studied. Three climate reconstructions were created: temperature reconstruction for Northern Finland and temperature and precipitation reconstructions for Eastern Finland.
