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."

    Message from William Farfan Rios (from Trocha Union):
    "I'm sending you some pictures of the new platform that we built in Trocha Union in the campsite close to the plot TRU-04. It was built with the effort and sweat of the UNSAAC students, some local people and the Chambasa. People who knows the place will appreciate this effort. Now this wonderful place will be even more beautiful to work, camp and enjoy the Nature.
    This infrastructure was possible thanks to Miles and Yadvinder's support."

    Dear Yadvinder

    Alex, Carlitos, Rudi, Flor, Jenifer and Jefferson finished installing a one-hectare plot in treeline between Acjanaco and Tres Cruces of the National Park of Manu.
    The elevation is 3500 m (0, 0) and its coordinate are 13º 08' 50.7"S, 71º 37' 57.6" W.

    Here are some photos of the one hectare plot.

    Publishing your photos?
    Maja Sundqvist, a post doc at SLU in Umeå, Sweden is writing a review on Community And Ecosystem Responses To Elevational Gradients: Processes, Mechanisms, And Insights For Global Change to be submitted to Annual Reviews in Ecology, Evolution and Systematics early 2013.
    She would like to include photos from a low, mid and high elevational site from our Andean transect in one of her figures. Would anyone have nice photos to contribute to her paper? If so, please send to (please add the photos to GEM, too!).

    Thank you,
