The carbon cycle of tropical forest in Lambir Hills, Sarawak

This project looks at the carbon cycle of two forest plots within the CTFS 52 ha plot in the Lambir Hills Nationa Park.

This tall majestic lowland diperocarp forest has the highest tree diversity recorded in the Paleotropics.

This research site is the DPhil project of Malaysian research student Kho Lip Khoon

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."
