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."

    I had to come back Peru two weeks ago when we had almost finished to set 2 plots up at Ducke Reserve. Karina Melgaço, Hellen Santana and Erick Oblitas students of Flavia Costa and Beto Quesada will complete the instalation of 10 plots. It is going to be a hard job but they will be able to do it! I have attached more pictures of the fieldwork...

    Report by Jhon del Aguilar

    We are currently installing 2 plots in the Ducke Reserve in Brazil, one in a baixio (low point in topography and other in plateau forest. Both represents the beginning of 10 permanent sample plots which will be monitored for INPA researchers/students.
    The study is conducted at Reserva Florestal Adolpho Ducke (RFAD) of the Instituto Nacional de Pesquisas da Amazônia (INPA), located near Manaus (02°55′S, 59°59′W). The reserve covers 10 000 (10×10 km) hectares of terra-firme tropical rain forest, with a closed canopy... More
