ABSTRACT
The official end of the International Biological Program (IBP) in 1974 was not the end. A central data bank was never achieved (Aronova, Baker, & Oreskes 2010:209). Computers were still in the early stages of development. The IBP ecosystem models were much less developed than expected, and an anticipated development of computer models was difcult for ecologists, and data from different biomes were not comparable (Mitchell et al. 1976:865). A handbook on Systems Analysis and Simulation in Ecology, in four volumes, appeared too late to guide the initial modeling, though it could assist in the reporting of results (Patten 1971-1975).
