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 ...

Dieback of the Amazon rainforest giants? Can tree hydraulics provide a clue?
Amazon tropical rainforests are increasingly impacted by el-Nino droughts. During those severe drought events, it is especially the large canopy trees that are dying. It is thought that the water relationships (i.e. hydraulics) of ...

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 ...

Forest dynamics in oak- beech forest
The Netherlands contain a significant proportion of Atlantic beech forest ecosystems. On the Veluwe, a number of old forest complexes contain well-developed forest ecosystems of this type in late-successional communities. The comm ...

The wonderful architecture of leaf veins and their role for plant hydraulics
Leaf veins provide not only structure to the leaves, but they are also the irrigation channels through which all water transport occurs. Plant species show an amazing variety in leaf vein architecture, which is not only esthetical ...

Why is the tree species composition in the Amazon changing? A functional trait approach
Permanent sample plots in the Amazon show that there is a directional change in tree species composition. The question is who are the winners (increasing in abundance), who are the loosers (decreasing in abundance), and why? Is it ...

Origin matters! Drought susceptibility of commercial Douglas Fir provenances
Can also be done as internship (24-27ects)
Douglas fir is a relevant timber species in European forestry. It grows well and produces valuable timber. The challenge for foresters is to choose those Douglas fir provenances for pl ...
