A mechanistic model for interpretation of hydrogen and oxygen isotope ratios in tree-ring cellulose

Climatic signals in tree-ring width and stable isotopes composition of <i>Pinus sylvestris</i> L. Growing in the industrialized area nearby Kędzierzyn-Koźle

“…The carbon isotopic composition (δ 13 C) of trees has been influenced by carbon isotopic composition of atmospheric CO 2 , diffusion of CO 2 through stomata, and enzymatic discrimination during the irreversible step of CO 2 fixation (Roden et al, 2000). The isotopic composition of plants varied due to emission of atmospheric pollution (Savard, 2010), such as for example sulphur dioxide (Rinne et al, 2010), carbon dioxide (Craig, 1954;McCarroll and Loader, 2004;Pazdur et al, 2007Pazdur et al, , 2013Sensuła et al, 2011aSensuła et al, , 2011bPazdur, 2013a, 2013b;Sensuła, 2015).…”

“…According to the scientific literature, the carbon isotopic composition in plant can vary with water stress and solar radiation and can be correlated with amount of rainfall, vapour pressure deficit, canopy position and hydraulic conductivity associated with tree height (Dongmann et al, 1974;Ehleringer, 1990;Ehrelinger and Vogel, 1993;Comstock and Ehleringer, 1992;Buchmann et al, 2002;Yoder et al, 1994;Barbour et al, 2002), whereas the oxygen isotopic composition of trees can be influenced by the oxygen isotopic composition of meteoric water and atmospheric vapour, atmospheric humidity and vapour pressure deficit (Farquhar and Lloyd, 1993;Roden et al, 2000). The oxygen isotopic composition of plant has been correlated with air temperature, relative humidity, transpiration rates and water balance, presumably all through contributions of source water (the xylem water in suberized stems) and leaf water enrichment (Ehrelinger and Vogel, 1993).…”

Regional And Watershed-Scale Coherence In the Stable-Oxygen and Carbon Isotope Ratio Time Series In Tree Rings Of Coast Redwood (Sequoia sempervirens)

“…Through a series of known fractionation events, d 18 O (and d 2 H) variation derived from hydrologic inputs is incorporated into the organic matter that makes up tree rings (Yapp and Epstein 1982;White et al 1994;Roden and Ehleringer 1999b;Roden et al 2000;Treydte et al 2006;Gessler et al 2009). Tree-ring cellulose d 18 O values can be modified by variation in atmospheric humidity and the unique isotope values it possesses, by vapor pressure deficit and therefore the magnitude of leaf evaporative enrichment associated with transpiration (Edwards and Fritz 1986;Roden and Ehleringer 1999a;Wright and Leavitt 2006;Kahmen et al 2008), by variation in source water (Wright et al 1999;Roden andEhleringer 1999b, 2007) and by post-photosynthetic but pre-biosynthetic factors shown to dampen the original isotope values of sucrose made at the leaf-level before it becomes incorporated into tree-ring cellulose (Brandes et al 2006).…”

“…Carbon isotope ratios (d 13 C) in tree-ring cellulose have been used to study historical variations in plant water status, temperature, solar radiation and vapor pressure deficit (Saurer et al 1995;Stewart et al 1995;Hemming et al 1998;Schleser et al 1999;Barbour et al 2002;Leavitt et al 2002;Young et al 2010). The mechanistic foundations for variation in cellulose d 13 C and d 18 O are now fairly well established (Farquhar et al 1982(Farquhar et al , 1989Roden et al 2000;Barbour et al 2004). Thus, absolutely dated time series of d 18 O and d 13 C variation in redwood tree rings have the potential to provide valuable historical records of climate variation and fog water utilization.…”
