- feature in international treaties and national legislation. Many of the tools that will be needed to fulfil
- the requirements of these policies are still in an early stage of development. One such tool is trophic
- ecosystem modelling. These models have been put forward to aid system-level understanding and
- provide insight into the potential impacts of human activities. Despite this, there are many gaps in
- knowledge of their strengths and weaknesses. In particular, little is known about the effect of the
- level of detail in a model on its performance. There has been some consideration of the effects of
- model formulation, as well as the effects of the physical, biological and chemical scope of multispecies
- and ecosystem models on their performance. A review of existing research indicates that
- there is a humped relationship between model detail and performance for these models, and that
- there are some guiding principles to consider during model development. This review gives some
- insight into which model structures and assumptions are likely to aid understanding and management,
- and which may be unnecessary. Further, it provides some understanding of whether some
- models can capture properties of real systems that other models cannot. The main recommendation
- is that the use of a single 'ultimate' ecosystem model is ill-advised, while the comparative and confirmatory
- use of multiple 'minimum-realistic' models is strongly recommended.</p></div><table style="margin-bottom: 1em" border="0" cellpadding="3" class="not_ep_block"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">Ecosystem, Multispecies, Model, Complexity, Model structure, Model scope</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/270702.html">270000 Biological Sciences > 270700 Ecology and Evolution > 270702 Marine and Estuarine Ecology (incl.
