November 8 (UPI) – According to Amazone's new study, the planet's greatest forest character changes its composition due to climate change.
Unfortunately, studies suggest that Amazon did not develop fast enough. Climate changes faster than Amazon can adapt.
Significantly scientists found moisture-loving species of trees die faster than they can be replaced by species that can withstand drier conditions. During the last decade, drought has damaged large parts of Amazon.
"The response of the ecosystem is lagging behind the speed of climate change," said Leavenworth University lieutenant Adriane Esquivel Muelbert in a press release. "Data showed that over the last decades, droughts in the Amazonian waters have had serious consequences for the forest composition, as mortality was the most vulnerable to tree species for drought and not enough growth in species that could survive the drier conditions."
The study, released this week in Global Change Biology, also showed that carbon dioxide emissions are increasing in the upper floor of the forest.
In addition, some smaller tree species benefit from increased carbon dioxide and the death of larger, moisture-loving trees.
Earlier studies have predicted that carbon dioxide concentration increases at least some degree of forest dynamics, allowing advanced species to increase their photosynthesis values and conquer a new area.
"Growth of some pioneer trees, such as very rapid growth cecropia, is consistent with the observed changes in forest dynamics, which may also ultimately lead to higher levels of carbon dioxide, "said Professor Oliver Phillips of Leeds Tropical Ecology.
Although change can help Amazons adapt to changing circumstances, rapid changes can destabilize ecosystems.
"The impact of climate change on forest communities has a significant impact on the biodiversity of rainforests," said Kyle Dexter of the University of Edinburgh. "The most vulnerable species of drought are in double risk because they are typically only in the heart of the Amazon, which makes them more likely to extinction if this process continues."
