Photosynthetic carbon isotope discrimination in trees: observations, predictions, and drivers

Abstract: Under elevated CO2, photosynthetic carbon isotope discrimination is expected to increase in response to photosynthesis stimulation driven by the growth of atmospheric CO2. While this response is widely documented in laboratory, field experiments and short-term observations, long-term proxies indicate that such response is not universally observed in forested ecosystems.

Impact of persistent droughts on forests in Mediterranean Chile

Global warming is concurrently associated with a rise in occurrences of drought episodes in numerous regions worldwide, with central Chile a sad example. This region is the only Mediterranean bioregion of South America, which is considered a biodiversity hotspot due to high endemism levels and high anthropic pressure. These ecosystems since 2010 have been impacted by a period of below-average rainfall, a so-called Mega Drought (MD), so their contribution to the regional carbon sink is at risk.
