Tropical forest temperature thresholds for gross primary productivity

Ecosphere, Volume 9, Issue 7, July 2018., 2018
Abstract Tropical forests are hyper‐diverse and perform critical functions that regulate global climate, yet they are also threatened by rising temperatures. Canopy temperatures depart considerably from air temperatures, sometimes by as much as air temperatures are projected to increase by the end of this century; however, canopy temperatures are ...
