Intact Amazon forests show possible signs of global warming impact

Climate change may be taking a hidden toll on intact rainforests in the heart of the Amazon, finds a new study based on 35 years of observations. 

The research, published in the journal Ecology, focused on the ecological impacts of fragmentation but unexpectedly found changes in the control forests. These shifts, which included faster growth and death rates of trees, increased biomass accumulation, and proliferation in vines, may be linked to rising carbon dioxide concentrations in the atmosphere, according to George Mason University's Thomas Lovejoy, who initiated the study in the late 1970's.
