Comparison of outputs based on three different modelling approaches for the response of an intertidal ecosystem to climate change.

Three simple ecosystem models were developed to provide an understanding of how the choice of ecosystem modelling approach influences conclusions. The first ecosystem model is based on functional (biomass-flux) interactions, the second ecosystem model is based on Lotka-Volterra interactions and the third ecosystem model is based on a goal-orientated approach. All modelled the response of a rocky intertidal ecosystem to climate change. Each type of model has been shown to lead to different conclusions when considering change in the abiotic environment. This highlights the importance of using models based on different perspectives to gain a more complete insight in to the response of ecosystems to climate change.
