Plant population and community modelling

The objective of plant population and community modelling in the Agroecology group is to understand, and where necessary anticipate, the effects on arable vegetation of technical innovations and global change, and thereby to understand the role of the vegetation in the sustainability of the arable system as a whole.  System-level responses, such as primary production, nutrient retention and biodiversity, emerge over time, often unpredictably, from complex ecological and evolutionary processes. By developing models of plant populations and communities, we are able to assess the response of arable vegetation in a way that can't be addressed by experiment or observation alone.

Our current focus is the influence of the genetic and functional characteristics (life-history traits or their physiological determinants) of plants on system-level properties. A common thread is the definition of populations and communities in terms of the genetic and functional variation of individuals. Using the individual enables intra- and inter-specific variation to be presented on a common scale and both ecological and evolutionary processes to be combined in a single model framework.
