Tropical wood density unraveled: effects of species, climate and tree size
Tropical forests store vast amounts of carbon and thus play an crucial role in the global carbon cycle. Changes in the carbon sequestration of tropical forests will thus have strong consequences for future climate: tropical forest ...

Understanding environmental effects on delta
13C and growth of tropical trees
Stable isotopes are variations of the same element in the number of neutrons in the core. They are chemically the same but differ in mass and therefore some biological processes discriminate against one of them. Carbon isotopes in ...

Can we link drought effects on tropical tree growth with tree mortality?
Droughts will reduce the capacity of tropical forests to sequester CO2 and store in in wood in the long run. This will have implications for the role of tropical forests in the global carbon cycle. Tree-ring analyses have revealed ...
