One question that I get quite frequently concerns how I/we construct our food web models. Well, one node/taxon/species at a time. This is just a little animation of the process, in this case for one of the Caribbean coral reefs (click on the figure if your browser does not animate it automatically). More detailed discussions may be found in these publications:
