Complete or overcompensatory thermal acclimation of leaf dark respiration in African tropical trees.

ABSTRACT: Tropical climates are getting warmer, with pronounced dry periods in large areas. The productivity and climate feedbacks of future tropical forests depend on the ability of trees to acclimate their physiological processes, such as leaf dark respiration (R_d ), to these new conditions. However, knowledge on this is currently limited due to data scarcity. We studied the impact of growth temperature on R_d and its dependency on net photosynthesis (A_n ), leaf nitrogen (N) and phosphorus (P) contents, and leaf mass per unit area (LMA) in 16 early-successional (ES) and late-successional (LS) tropical tree species in multispecies plantations along an elevation gradient (Rwanda TREE project). Moreover, we explored the effect of drought on R_d in one ES and
