Beschreibung:
Coupled climate-carbon cycle models suggest that Amazon forests are vulnerable to both long- and short-term droughts, but satellite observations showed a large-scale photosynthetic green-up in intact evergreen forests of the Amazon in response to a short, intense drought in 2005. These findings suggest that Amazon forests, although threatened by human-caused deforestation and fire and possibly by more severe long-term droughts, may be more resilient to climate changes than ecosystem models assume.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saleska, Scott R -- Didan, Kamel -- Huete, Alfredo R -- da Rocha, Humberto R -- New York, N.Y. -- Science. 2007 Oct 26;318(5850):612.
