Species-specific shifts in diurnal sap velocity dynamics and hysteretic behavio...
Gimenez, Bruno Oliva; Jardine, Kolby J.; Higuchi, Niro; Negrón-Juárez, Robinson I.; Sampaio-Filho, Israel de Jesus; Cobello, Leticia OliveiraCurrent climate change scenarios indicate warmer temperatures and the potential for more extreme droughts in the tropics, such that a mechanistic understanding of the water cycle from individual trees to landscapes is needed to adequately predict future changes in forest structure and function. In this study, we contrasted physiological responses of tropical trees during a normal dry season with the extreme dry...
The Central Amazon Biomass Sink Under Current and Future Atmospheric CO2: Predi...
Holm, Jennifer A.; G, Knox, Ryan; Zhu, Qing; Fisher, Rosie A.; Koven, Charles D.; Nogueira Lima, Adriano J.; Riley, William J.; Longo, MarcosThere is large uncertainty whether Amazon forests will remain a carbon sink as atmospheric CO2 increases. Hence, we simulated an old-growth tropical forest using six versions of four terrestrial models differing in scale of vegetation structure and representation of biogeochemical (BGC) cycling, all driven with CO2 forcing from the preindustrial period to 2100. The models were benchmarked against tree inventory...
