certain model details it is usually possible to correct them. However, if basic
decisions like which model structure to use are inadequate, regardless how good
the rest is, the entire modelling work could be compromised.
In early years of ecological modelling the focus was on quantitative transitions
in structurally fixed networks. Nowadays, things have become more challenging
and demanding. The overview has to encompass not only quantitative transitions
but also qualitative and structural dynamics. It requires a basic insight in the
biotic interactions and a very clear definition of what is considered the focus of
interest.
Afterward a representation of the basic interactions to be included is possi-
ble. Only then can the decision be made as to which modelling technique is
the most suitable. The way abstractions are made is different for the various
approaches.
It is useful to move beyond the commonly applied practices to select the
problems according to the techniques one is able to handle, and not the other way
around. It is better to choose from a larger range of different tools, according to the
state-of-the-art of current ecological modelling techniques. This strategy is not only
more efficient and appropriate. It also helps to maintain the quality of the theoretical
analysis with the diverse requirements of modern ecological issues.
