Effects of climate change on grassland biodiversity and productivity: the Need for a diversity of models
Résumé
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.
