- 1999
Global and seasonal data are presented, a proximate mechanism for the overall relationship between water availability and ecosystem delta(15)N is postulated and, newly, a mechanism accounting for the highly delta( 15)N-depleted values found in the foliage and soils of many wet/cold ecosystems is proposed.
Spatial, Species, and Temporal Variations in the13C/12C Ratios of C3Plants: Implications for Palaeodiet Studies

- 1 June 1999
The δ13C value of a C3plant is influenced by the species’ response to its environment, which is subject to natural changes with space and time. This paper reviews the magnitude of the resulting…
