                         important component of the carbon cycle in tropical forests. Aims: 
                         This study analyses WD (>2 cm) and other above-ground fluxes in 
                         mature tropical forest plots along an elevational gradient 
                         (2103025 m above sea level) in southern Peru. Methods: This work 
                         was based on inventories of fine and coarse WD (FWD and CWD, 
                         respectively), above-ground biomass, and field-based and 
                         experimental respiration measurements. Results: Total WD stocks 
                         ranged from 6.26 Mg C ha\−1 at 3025 m to 11.48 Mg C 
                         ha\−1 at 2720 m. WD respiration was significantly 
                         correlated with moisture content (P < 0.001; R 2 = 0.25), 
                         temperature (P < 0.001; R 2 = 0.12) and wood density (P < 0.001; R 
                         2 = 0.16). Controlled experiments showed that both water content 
                         and temperature increased respiration rates of individual WD 
                         samples. The full breadth of the temperature sensitivity 
                         coefficient, or Q 10, estimates, ranging from 1.142.13, was low 
                         compared to other studies. In addition, temperature sensitivity of 
                         WD respiration was greater for higher elevations. Conclusions: 
                         Carbon stocks, mortality and turnover of above-ground biomass 
                         varied widely and were not significantly related with elevation or 
                         slope. This study demonstrates that some forests may be a carbon 
                         source due to legacies of disturbance and increasing temperatures, 
                         which may cause additional, short-term carbon efflux from WD. 
                         Predictions of tropical forest carbon cycles under future climate 
                         should incorporate WD dynamics and related feedback.",
