    Reconstructing the Benguela ecosystem for a time before man's intervention
    (2007) Watermeyer, Katherine Eleanor; Shannon, L J; Griffiths, Charles L
    The aim of this thesis is thus to explore and describe any ecosystem-level changes that may have occurred since fishing and exploitation began in the Benguela, in terms of both structure and function. This will be investigated using Ecopath with Ecosim (EwE) There are currently available, models of the Benguela ecosystem based on modern catch and biomass data that cover the period from the 1970, or '80s, until the 2000s (Shannon et at., 2003; Heymans et al., 2004, Roux & Shannon, 2004).
