Slide 3 : Dynamic Vegetation Models
An example of an ecosystem function model used in relation to climate change are the 'dynamic global vegetation models (DGVMs) that link to the Global Circulation Models (GCMs) and provide a changing land surface to them. These models simulate the carbon uptake and loss of the surface features, the albedo, the bulk stomatal conductivity, and the roughness of the surface as it interacts with the atmosphere. Of course, since it is dealing with a GCM (which typically have very broad scales) the best that these models have is a very crude representation of several biomes, or functional types. However, some of the better models, such as the LPJ model or the Sheffield DVGM) also include such processes as fire, and the interactions of mammals.
