Population interactions modelled by bond graphs (Q1095073)

Bond graph analysis is applied to a category of ecosystems which examines trophic interactions between populations. A bond graph model for a trophic food chain is analysed, and correlation to Lotka-Volterra dynamics reveals the nature of all the conjugate variables and permits the cause-effect relationships of the mass-energy transformations to be modelled explicitly. Other models are considered, as well as thermodynamic restrictions imposed by the graph topology of the systems.
