Tropical forests have immense carbon storage potential. But in the midst of a changing climate, how resilient can these forests be? A recent study, led by CBS faculty member Chris Smith-Martin suggests that tropical tree species may have more ability to survive in the face of drought than thought before. Smith-Martin and colleagues examined physiological traits associated with drought resistance in 18 tree species across regions with varied rainfall in Puerto Rico.
“The most exciting finding from this study is that within the same species, individuals in the drier sites tended to be overall more drought resistant than individuals of the same species in the wetter sites,” says Smith-Martin. “In the face of climate change, this is potentially good news, because they can adjust their drought resistance across the rainfall gradient.”
