Subproject

PELD - Caxiuanã

PELD - O Programa de Pesquisas Ecológicas de Longa Duração (PELD) tem como foco o estabelecimento de sítios de pesquisa permanentes em diversos biomas e ecossistemas do Brasil, integrados em rede para o desenvolvimento e o acompanhamento de pesquisas ecológicas de longa duração, com o objetivo de obter informações relevantes sobre aspectos fundamentais para a Conservação da Biodiversidade e Uso Sustentável dos Recursos Naturais dos ecossistemas brasileiros.

Cooperation between Emilio Goeldi Museum and the GEM network. This project monitors several plots from the igapó foodplain forest (Curuá river) and várzea foodplain forest (Baia de Caxiuanã) being monitored under the PELD Caxiuanã project in the Caxiuana National Forest with 33.000 km2 in the Oriental Amazonian, Pará State, Brazil.

Congratulations to the GEM team (Chris, Yadvinder & Liana) who co-authored a paper in Nature this week (cover story):

"The paper answers a long-standing question about the net carbon balance of the Amazon forest. It uses aircraft flights throughout the year at four different locations to measure the change in carbon dioxide concentration if air as it passes over the Amazon Basin. The study shows that in wet years and wet seasons the Amazon is a net sink (i.e. absorbs carbon) from the atmosphere, but in dry years and dry seasons it is carbon neutral or a source of carbon. Our main contribution in Oxford was to provide insight from our RAINFOR-GEM intensive monitoring plots across Amazonia, which suggest that the loss of the carbon sink was caused by a reduction in photosynthesis."
