WebThe general theory predicts that organisms as a whole tend towards optimality within the context of the variation present and the constraints of the environment. Optimality is signifi- cant solely in terms of the full range of selective pressures operating on an organism. Webreveals a different meaning to the term theory, as used in ecology, than in more traditional science philoso-phy (e.g. Popper 1959). Possibly because modern hydrology is also a rela-tively young scientific discipline, the development of its theory is in a state equivalent to that of ecology. It is ironic that Bras & Eagleson (1987) used ecological
