Zeng et al. (1990, henceforth denoted ZPE) found chaotic behavior in daisyworld (Watson and Lovelock, 1983, henceforth denoted WL), a simple nonlinear model of an idealized world con- taining only species of daisies of various albedos. The planetary albedo depends on the coverage of each type of daisy, and the daisies have temperature-dependent growth rates, enabling feedback between the environment (temperature) and the biota (daisies).
