Summary
This pan-latitudinal analysis of tree species across the Americas reveals fundamental life history trade-offs between growth and longevity that structure demographic variation across forest biomes. The authors classify trees into four demographic functional types and demonstrate that the strength of growth-longevity trade-offs varies predictably with temperature, whilst trait diversity correlates positively with forest productivity. These findings provide new understanding of the demographic mechanisms governing carbon turnover rates and terrestrial carbon balance across global forest systems.
Regional applicability
This study focuses on American forests and does not directly assess United Kingdom conditions. However, the framework for classifying demographic functional types and understanding growth-longevity trade-offs may have relevance for UK woodland management, particularly in temperate zones, though direct application would require complementary studies on native UK tree species and validation within British forest conditions.
Key measures
Life expectancy at 10 cm diameter, growth rates, longevity, demographic functional types, trait diversity indices, forest productivity, temperature gradients across biomes
Outcomes reported
The study mapped life history traits (growth and longevity) across tree species in the Americas and classified them into four demographic functional types, revealing variation in life expectancies from 1.3 to 3195 years at 10 cm diameter. The analysis identified emergent patterns in growth-longevity trade-offs across temperature gradients and a positive relationship between trait diversity and forest productivity.
