Package: ATNr 1.1.0

Benoit Gauzens

ATNr: Run Allometric Trophic Networks Models

Implements the differential equations associated to different versions of Allometric Trophic Models (ATN) to estimate the temporal dynamics of species biomasses in food webs. It offers several features to generate synthetic food webs and to parametrise models as well as a wrapper to the ODE solver deSolve.
