Terrestrial plant biomarkers and their carbon isotopes provide insights into carbon cycling,
paleovegetation and paleoclimate, ranging in scale from local to global. Over the past …

The mechanistic understanding of isotope fractionation processes is increasing but we still
lack detailed knowledge of the processes that determine the isotopic composition of the tree …

Tree-ring dating (dendrochronology) is a method of scientific dating based on the analysis of
tree-ring growth patterns. As author James Speer notes, trees are remarkable bioindicators …

▪ Abstract The use of stable isotope techniques in plant ecological research has grown
steadily during the past two decades. This trend will continue as investigators realize that …

Stable isotopes in tree rings could provide palaeoclimate reconstructions with perfect annual
resolution and statistically defined confidence limits. Recent advances make the approach …

The rate of CO 2 assimilation by plants is directly influenced by the concentration of CO 2 in
the atmosphere, ca. As an environmental variable, ca also has a unique global and historic …

Aim The goals of this study are:(1) to determine whether increasing atmospheric CO2
concentrations and changing climate increased intrinsic water use efficiency (iWUE, as …

人类活动在全球范围内极大地改变着氮素从大气向陆地生态系统输入的方式和速率,
人为固定的氮素正在不断积累, 并对生态系统的结构和功能产生显著影响. 该文从以下几个方面 …

We revisit the relationship between plant water use efficiency and carbon isotope signatures
(δ 13 C) of plant material. Based on the definitions of intrinsic, instantaneous and integrated …

We investigated the response of conifer trees in northern Eurasia to climate change and
increasing CO2 over the last century by measuring the carbon isotope ratio in tree rings …
