  31. end an ecosystem model of a generalised temperate bay, Bay Model 2 (BM2), was constructed. It is a trophically diverse
  32. biogeochemical model built using the functional groups from another ecosystem model, the Integrated Generic Bay Ecosystem
  33. Model (IGBEM) and the general framework from a model of Port Phillip Bay (PPB), Australia. BM2 captures the essential
  34. features of real marine systems, it is also capable of reproducing realistic levels of biomass and conforms with known ecological
  35. relationships. The model's performance is not as good for some of the poorly known groups (like infauna) or when environmental
  36. conditions undergo extreme change. Despite this, the overall performance of BM2 indicated, it is as capable of representing
  37. systems as accurately as more physiologically detailed ecosystem models, such as IGBEM. This shows that physiological detail
  38. is not always required and that simpler formulations, such as those employed in BM2, are generally adequate for learning and
  39. general predictive purposes. This is important because, in comparison with IGBEM, BM2 uses substantially fewer parameters

To this&#13;
  370. end an ecosystem model of a generalised temperate bay, Bay Model 2 (BM2), was constructed. It is a trophically diverse&#13;
  371. biogeochemical model built using the functional groups from another ecosystem model, the Integrated Generic Bay Ecosystem&#13;
  372. Model (IGBEM) and the general framework from a model of Port Phillip Bay (PPB), Australia. BM2 captures the essential&#13;
  373. features of real marine systems, it is also capable of reproducing realistic levels of biomass and conforms with known ecological&#13;
  374. relationships. The model's performance is not as good for some of the poorly known groups (like infauna) or when environmental&#13;
  375. conditions undergo extreme change. Despite this, the overall performance of BM2 indicated, it is as capable of representing&#13;
  376. systems as accurately as more physiologically detailed ecosystem models, such as IGBEM. This shows that physiological detail&#13;
  377. is not always required and that simpler formulations, such as those employed in BM2, are generally adequate for learning and&#13;
  378. general predictive purposes. This is important because, in comparison with IGBEM, BM2 uses substantially fewer parameters&#13;
  379. and has lower development, computation and maintenance costs.&#13;
