Supplement 1. Source code for simulations.

File List scanning.tar.gz -- Compressed archive with the C source code files README -- Instructions for compilation and use Description This program 'xscanning' performs a given number of numerical integrations for the multispecies Droop model. The simulation parameters are described in the 'header.h' file, and can be modified there. These parameters include: BAND : the dominant band of the R-star matrix MAX : the number of species(=resources) RRANGE: the range from which the R-star values are chosen FRANGE: the range from which the F-hat values are chosen RUNS : the number of runs TIME : the number of days per run The program takes care of the generation of V, K, and Q matrices according to the rules described in Appendix A. The source code is written in ANSI-C and makes use of the GNU Scientific Library for numerical integration of ordinary differential equations http://www.gnu.org/software/gsl/.
