Much of our current theoretical understanding of predator-prey interactions is based on studies and mathematical models developed for single-prey, single-predator systems. However, ungulates, like most other species, are commonly part of complex multi-species communities. Predicting outcomes of species interactions in such systems is difficult but necessary to implement meaningful conservation and management strategies. In this session we attempt to summarize current knowledge of ungulate population dynamics in multi-species systems focusing on 3 different scenarios: A) one ungulate prey species, multiple predators; B) multiple ungulate prey species, one predator; and C) multiple ungulate prey species, multiple predators. Summaries of case studies as well as advances in modelling predator-prey interactions in multi-species systems will be used to develop a conceptual framework for understanding impacts of predators in complex ecological systems.
