2) Drought in an E. Amazonian rain forest: effects of the exclusion of rainfall from soil on litterfall and treegrowth.S. Almeida 1 , R. Santos 1 , ACL Costa 2 , J. Grace 3 , Y. Malhi 3 , P. Meir 31. Museu Paraense Emílio Goeldi (Brazil) 2. Universidade Federal de Pará (Brazil). 3. University of Edinburgh (UK).Rainfall was experimentally excluded from 1 ha of E. Amazonian forest, at Caxiuana National Forest, Para usingtransparent plastic panels placed 1.5-2.5 m above the ground. Measurements were made of litterfall and tree growthbefore and after installation of the rainfall exclusion infrastructure. Comparisons were made between adjacent control andtreatment plots (1 ha) and with data obtained from a third plot 2km away, where weather and ecosystem fluxmeasurements were also made. The effects of reduced soil moisture on the seasonality in litterfall and the annual treegrowth rate are discussed in the context of seasonality in the forest carbon cycle.
