The International Society for Ecological Modelling (ISEM) sponsors conferences, workshops and training courses with the aim of advancing the development of ecological and environmental modelling. The 3rd International Conference on the state-of-the-art in ecological modelling was sponsored by the ISEM in cooperation with the National Park Service Water Resources Laboratory and hosted by the Natural Resource Ecology Laboratory at Colorado State University. Its theme was the application of ecological modelling to environmental management and this book contains the full texts of the three invited papers presented in the five general sessions, plus the final summaries and syntheses of the topics covered during those sessions.

Economic analysis of beef cattle production has been limited by the inability to fully describe the underlying production process. Except for confined feeding of cattle, beef cattle production is the process of growing cattle who consume forages. The animal and the forage possess attributes of both factors and products of production. The production of forage constitutes one production process, animal growth is another production process, and reproduction by female animals is a third production process. Cattle production involves all three processes in such a manner that each influences the outcome of the other. Each process is itself complex and analysis is further complicated when all three are considered simultaneously.
