| Popis: | Quantifying carbon dynamics in forests is critical for understanding their role in long-term climate regulation 1â4 .Yet little is known about tree longevity in tropical forests 3,5â8 ,a factor that is vital for estimating carbon persistence 3,4 .Here we calculate mean carbon age (the period that carbon is fixed in trees 7 ) in different strata of African tropical forests using (1) growth-ring records with a unique timestamp accurately demarcating 66 years of growth in one site and (2) measurements of diameter increments from the African Tropical Rainforest Observation Network (23 sites). We find that in spite of their much smaller size, in understory trees mean carbon age (74 years) is greater than in sub-canopy (54 years) and canopy (57 years) trees and similar to carbon age in emergent trees (66 years). The remarkable carbon longevity in the understory results from slow and aperiodic growth as an adaptation to limited resource availability 9â11 .Our analysis also reveals that while the understory represents a small share (11%) of the carbon stock 12,13 ,it contributes disproportionally to the forest carbon sink (20%). We conclude that accounting for the diversity of carbon age and carbon sequestration among different forest strata is critical for effective conservation management 14â16 and for accurate modelling of carbon cycling 4 .© 2019, The Author(s), under exclusive licence to Springer Nature Limited.
