Future ash trees - screening and selection of common ash for resistance to ash dieback
Ash dieback spreads across Europe and causes leaf loss, crown dieback and bark lesions in affected ash trees (Fraxinus excelsior). Once a tree is infected the disease is usually fatal. Results from Denmark indicate that ca 1% of a ...

Comparing the ecology across European tree species
Project description: Foresters modify the structure and light environment of forests to manage the future development of the forest. Natural regeneration and competition between different species are important in current forest ma ...

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 ...

The distribution of genetic diversity of main tree species over Europe
Genetic diversity (GD) is the base of adaptation to environmental changes such as climate change. To use and conserve GD, Gene Conservation Units (GCUs) are installed throughout Europe (see: www.eufgis.org; www.euforgen.org). The  ...

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  ...
