Vianny Natugonza, Cameron Ainsworth, Erla Sturludóttir, Laban Musinguzi, Richard Ogutu-Ohwayo, Tumi Tomasson, Chrisphine Nyamweya, Gunnar Stefansson
2018 bioRxiv   pre-print
In this study, we compared outputs of two ecosystem models, Ecopath with Ecosim (EwE) and Atlantis, for Lake Victoria under different fishing pressure scenarios.  ...  We compared model behaviour at the ecosystem level, and also at a level of functional groups.  ...  Functional groups used in the Lake Victoria EwE and Atlantis models.
