Amazone is developing but not adapted as quickly as the climate changes


November 8 (UPI) – According to the new Amazon survey, the largest forest in the planet is changing its composition in response to climate change.

Unfortunately, the study suggests that Amazon is not developing fast enough. The climate is changing faster than Amazon can adapt.

Most noticed that scientists have found that wetland tree species die faster than it can be replaced by species resistant to more dry conditions. Drought in recent decades has been damaged in large parts of the Amazon.

"The ecosystem reaction lags behind the number of climate change," said Georges Adriane Esquivel Muelbert, Leeds University, in a news release. "These data showed that during the drought in recent years, the Amazon basin has had serious consequences for forest composition, higher mortality from tree species most affected by drought and insufficient compensation for species that are better equipped to survive in the driest conditions. "

The poll, published this week in the magazine Global Change Biology, also showed that rising carbon dioxide levels in the upper ecosystem of the forest are beneficial.

In addition, some smallest species of trees benefit from the increase in CO2 and the death of more moisture-loving trees.

Previous studies have predicted that rising CO2 levels will accelerate at least part of the forest dynamics, allowing species to increase photosynthesis rates and conquer new territory.

"The growth of some pioneering trees, for example, is growing fast Cecropiais consistent with the observed changes in forest dynamics, which can ultimately result from increased levels of carbon dioxide, "said Oliver Fillips, Professor of Tropical Ecology at Leeds.

While changes can help Amazon adapt to changing conditions, rapid changes can destabilize ecosystems.

"The impacts of climate change on forest communities have a significant impact on the biodiversity of rainforests," said Kyle Dexter of Edinburgh University. "The most vulnerable species of drought are subject to dual risk, as they are usually only available for smaller sites in the heart of the Amazon, which are likely to disappear if this process continues."
