Stem cell development compared across species: from cambium to xylem and phloem cells
Xylem and phloem cell development in plant stems has been described in qualitative sense, but comparative and quantitative analyses that are required for understanding differences in stem development and functioning across plant s ...

Growth responses to thinning in douglas fir
Douglas fir (Pseudotsuga menziesii) is one of the most productive tree species in European forests. Douglas fir stands are maintained by thinning until a point where regeneration is started and the old trees removed. Conventional ...

Individual increment functions for douglas fir
Kroondomein Het Loo (a large forest estate near Apeldoorn) and the FEM group recently established two marteloscopes in douglas fir stands. Marteloscopes are forests especially designed for doing exercises in forest management. All ...

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 ...

Planting strategies for reforestation of dryland areas
Topic ia also suitable for more students, or as an Internship
Reforestation of dryland areas is a major challenge the coming decade. If natural regeneration is not an option or too slow, planting may be necessary. Key questions ...

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 ...

How do woody species differ in hydraulic architecture?
Hydraulic architecture refers to form characteristics of plants that characterize the water relationships. The Huber value, named after a German researcher active in the 20/30-ties of the 20th century, is the ratio between the sap ...

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 ...
