Tropical Trees Resilient to Drought
When people think of tropical trees, they often remember water. So what happens if a tropical tree suffers from a drought? Well, recent studies show that tropical trees have a unique method to fight back against drought. Trees, in general, transport water and nutrients from the ground through their roots, then through their xylem–the scientific name for wood. If there is less water, then the tree has to "suck" harder which could lead to the point where they suck air bubbles. The bad thing about this is that, this will cause an embolism similar to a human having a blood clot. The more embolisms a tree has, the more susceptible it is to drought. The problem with tropical trees suffering through drought is that they store carbon that reduces global warming. If those plants die and decompose because of the drought, they become a source of atmospheric carbon. The Amazon alone stores about 20 percent of all carbon in the Earth biomass. The good thing is th...
