Ever since Charles Darwin’s times evolutionary arguments have been essential part of biological research. In modelling they can be included by formulating them as optimisation problems. Optimality models can be used e.g. estimating growth allocation in different environments.
Interaction of structure and function
The more fine roots the higher nutrient uptake. The interconnections between tree structure and metabolic functions like photosynthesis and transport of substances can be used in modelling the tree growth and resource allocation. Further information
Hierarchy, modularity and summary models
An increased interest on wood quality and more complex stand structures also in managed forests have created a need for new models. Our group has developed models for individual tree growth throughout the rotation using a hierarchical-modular approach.
