Long-term thermal sensitivity of Earth’s tropical forests
Sullivan, Martin J. P.; Lewis, Simon L.; Affum-Baffoe, Kofi; Castilho, Carolina; Costa, Flávia; Sanchez, Aida Cuni; Ewango, Corneille E. N.The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses. Here, we analyze 590 permanent plots measured across the tropics to derive the equilibrium climate controls on forest carbon. Maximum temperature is the most important p...
Hyperdominance in Amazonian forest carbon cycling
Fauset, Sophie; Johnson, Michelle O.; Gloor, Manuel U.; Baker, Timothy R.; Monteagudo M, Abel; Brienen, Roel J.W.; Feldpausch, Ted R.While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few â € hyperdominantâ €™ species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing more carbon than any other ecosystem on Earth. Here we ask, using a unique data set of 530 forest plots, if the functions of storing and produci...
Compositional response of Amazon forests to climate change
Esquivel-Muelbert, Adriane; Baker, Timothy R.; Dexter, Kyle Graham; Lewis, Simon L.; Brienen, Roel J.W.; Feldpausch, Ted R.; Lloyd, JonMost of the planet's diversity is concentrated in the tropics, which includes many regions undergoing rapid climate change. Yet, while climate-induced biodiversity changes are widely documented elsewhere, few studies have addressed this issue for lowland tropical ecosystems. Here we investigate whether the floristic and functional composition of intact lowland Amazonian forests have been changing by evaluating ...
