Daisy World

At the same time, one should be aware that the advocates of Gaia posed the problem of the homeostatic properties of the biosphere more precisely than Vernadsky himself based on data collected in the 50 years after Vernadsky wrote down his conclusions. Vernadsky was in no position to make a numerical model of the biosphere comparable with the daisy world modeP and other models of Gaia (Schellnhuber, Wenzel, 1998). In the Vernadskian tradition mathematical modelling of the biosphere was pioneered by Moiseev with colleagues (e.g., Moiseev et aL, 1985).
