A still very much in development R package for Ecological Network Dynamics
Currently the package will simulate the dynamics of food webs based on the bioenergetic model described by:
Williams, R. J. and Martinez, N. D. 2005. Diversity, Complexity, and Persistence in Large Model Ecosystems. - In: Pascual, M. and Dunne, J. A. (eds), Ecological Networks: Linking Structure to Dynamics in Food Webs. Oxford University Press, pp. 163–186.
