Pioneer Mimosa and their life history in the dry tropics
Also possible as Internship.
Old-growth tropical dry forests are continuously decreasing in area because of land use change. Slash-and-burn agriculture is a common practice used in the tropics to open areas for agriculture. The ...

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 ...

The role of Neotropical primates on tropical forests
Plant animal interactions in Tropical forests. Understanding the effect that primates have on forest development and possible cascading effects.
For this project we are interested in determining the effect that primates have on ...

Seed rain during secondary succession in tropical wet forest in Mexico
Secondary forests, regrowing after agricultural fields are abandoned, need input of seeds to develop. The seed rain (number and type of seeds) partly determine the possible growth trajectories of these forests. In this project, y ...

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 ...
