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 ...

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 ...

Anatomical traits regulate cavitation resistance in conifer tree species
Conifers (co-)dominate in many forests in different climates across the temperate zone, with some species better adapted to cold or dry habitats than others. Their wood anatomical traits (i.e., extremely narrow tracheid size and ...

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 ...
