The Patagonian Transect

A range of plant parameters were studied in Patagonia including vegetation types ranging from tall forest to desert (Fig. 2, Schulze et al., 1996). Only root biomass and density in the top soil decreased linearly with rain fall. All other parameters, either changed in a threshold manner (such as LAI) or remained constant.
