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...
Height-diameter allometry of tropical forest trees
Feldpausch, Ted R.; Banin, Lindsay F.; Phillips, Oliver L.; Baker, Timothy R.; Lewis, Simon L.; Quesada, Carlos Alberto; Affum-Baffoe, KofiTropical tree height-diameter (<i>H:D</i>) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry. We have therefore developed a new global tropical forest database consisting of 39 955 concurrent <i>H</i> and <i>D</i> measurements encompassing 283 sites in 22 tropical countries. Utilising this data...
Tree height integrated into pantropical forest biomass estimates
Feldpausch, Ted R.; Lloyd, Jon; Lewis, Simon L.; Brienen, Roel J.W.; Gloor, Manuel E.; Monteagudo-Mendoza, Abel; Lopez-Gonzalez, GabrielaAboveground tropical tree biomass and carbon storage estimates commonly ignore tree height (H). We estimate the effect of incorporating H on tropics-wide forest biomass estimates in 327 plots across four continents using 42 656 H and diameter measurements and harvested trees from 20 sites to answer the following questions: ; 1. What is the best H-model form and geographic unit to include in biomass models to mi...
Diversity and carbon storage across the tropical forest biome
Sullivan, Martin J.P.; Talbot, Joey; Lewis, Simon L.; Phillips, Oliver L.; Qie, Lan; Begne, Serge K.; Chave, Jérôme; Cuni, Sanchez, Aida; Hubau, WannesTropical forests are global centres of biodiversity and carbon storage. Many tropical countries aspire to protect forest to fulfil biodiversity and climate mitigation policy targets, but the conservation strategies needed to achieve these two functions depend critically on the tropical forest tree diversity-carbon storage relationship. Assessing this relationship is challenging due to the scarcity of inventorie...
