摘要: Several recent ecosystem studies provide evidence that plant discrimination against 13 C during photosynthesis is highly variable on synoptic to interannual timescales. Critical axes of variation include the response drought stress in temperate and tropical forests shifts abundance 3 4 vegetation both land use climate. This chapter aims place this variability context global carbon cycle. First, it presents equations describing atmospheric budget for CO 2 12 graphical form, using “Robin Hood” diagrams. Robin Hood diagrams an intuitive means comparing isotopic fluxes from terrestrial ecosystems with those oceans fossil fuels, partitioning ocean sinks δ observations. Second, critically reviews mechanisms by which are thought impart anomalies atmosphere
