Announcing mizer 3.3
steady() and projectToSteady() have been renamed to tuneSteadyState() and findSteadyState(), after what each of them keeps fixed. mizer 3.3 can also tell you whether your model is actually at its steady state, find steady states that are dynamically unstable and analyse why, and scan a model over a range of parameter values to produce yield curves and bifurcation diagrams. The topic articles and the AI-agent skills have become one set of documents, so your agent reads the same guides you do.

Density-dependence in reproduction
The take-home message is that it is important to set the density dependence in your model appropriately and that with the help of the setBevertonHolt() function you can easily make changes to the density dependence without spoiling other aspects of your calibrated model.
