Multi-species sIZE spectrum modelling in R

A set of classes and methods to set up and run multispecies, trait based and community size spectrum ecological models, focussed on the marine environment.


mizer is a package that implements size-based ecological models. The package has been developed to model marine ecosystems that are subject to fishing. However, it may also be appropriate for other ecosystems.

The package contains routines and methods to allow users to set up the model community, and then project it through time under different fishing strategies.

Methods are included to explore the results, including plots and calculation of community indicators such as the slope of the size spectrum. Size-based models can be complicated so mizer contains many default options that can be easily changed by the user.

See the accompanying vignette, "mizer_vignette", for more details on how the package works including detailed examples.

News

  • Release to coincide with the submission of the MEE paper. No major changes. Just minor bug fixes.
  • Beta release - just about works but still some gremlins to sort out. There are a number of features I'd like to add in the coming relases.
