“…Individual-based modelling (IBM) represents each plant individually, along with information about how its state changes over time influenced by other individual plants (Berger et al, 2008;Grimm and Railsback, 2004). This approach has been successfully applied to represent heterogeneity across space, time and among species in crop-weed competition Munier-Jolain et al 2013Berger et al, 2013). A still more detailed approach is functionalstructural plant modelling (FSPM) where each plant is represented explicitly as being made up of separate components that are topologically and geometrically defined and related, typically to the level of detail where the geometry of each component is represented in some detail.…”

“…Models of grassland dynamics based on the explicit simulation of growth and development of different species in a community and of the competition among them can reflect detailed knowledge of the underlying system. Such models tend to be implemented as three-dimensional, individual-based [54] or even sub-individual-based [55] competition models. The complexity and parameter-richness of these models makes them difficult to initialize and parameterize.…”

Effects of Climate Change on Grassland Biodiversity and Productivity: The Need for a Diversity of Models

2018

There is increasing evidence that the impact of climate change on the productivity of grasslands will at least partly depend on their biodiversity. A high level of biodiversity may confer stability to grassland ecosystems against environmental change, but there are also direct effects of biodiversity on the quantity and quality of grassland productivity. To explain the manifold interactions, and to predict future climatic responses, models may be used. However, models designed for studying the interaction between biodiversity and productivity tend to be structurally different from models for studying the effects of climatic impacts. Here we review the literature on the impacts of climate change on biodiversity and productivity of grasslands. We first discuss the availability of data for model development. Then we analyse strengths and weaknesses of three types of model: ecological, process-based and integrated. We discuss the merits of this model diversity and the scope for merging different model types.

“…Such a fractal organization of their outer surface may be a feature contributing to high efficacy of plants for light interception. Several recent studies suggest the importance of the three-dimensional and multiscale organization of plants in efficient light interception [59][60][61]. The depth images and their association with luminance images as investigated here, can contribute to the analysis and modeling of these processes of light interaction and interception by plants.…”
