predicting the potential demographic impact of predators on their prey: a comparative analysis of two carnivore-ungulate systems in scandinavia. | 1. understanding the role of predation in shaping the dynamics of animal communities is a fundamental issue in ecological research. nevertheless, the complex nature of predator-prey interactions often prevents researchers from modelling them explicitly. 2. by using periodic leslie-usher matrices and a simulation approach together with parameters obtained from long-term field projects, we reconstructed the underlying mechanisms of predator-prey demographic interactions and compared the dynamics o ... | 2011 | 22077484 |
