Some trees grow faster than others: why?
Within populations of trees, there are substantial differences in the growth rates of equal-sized trees. Such growth differences between individuals can persist for several decades, and cause trees to strongly differ in age when t ...

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 ...

How old is this tropical forest tree? (And how to estimate that?)
There’s a lot of discussion about the (maximum) ages of trees in tropical forests. Some scientists consider that thousand-year old trees are rather common, while others believe this is unlikely. Apart from this fundamental questio ...

Understanding how pruning affects flowering and fruiting intensity and pattern in cocoa trees ( Theobroma cacao L. ).
Cacao is the most important export crop in west African countries such as Ivory Coast and Ghana and an essential source of income for millions of small older farmers. Realized yield however falls way below the potential value calc ...

Historic wood use in Costa Rica and its contribution to climate change mitigation
Internship or thesis Tropical forests play a major role in the global carbon cycle. The prevention of deforestation and sustainable management of these forests is therefore included in climate mitigation measures, such as outli ...
