Web[Tilman (1982)] proposed a model in which di erent species compete for a single resource (see [Miller et al. (2005)] for a review). Species’s growth rates are proportional to resource availability and their consumption rate. This theory predicts that the only species that will survive is the one that has the highest consumption rate (lowest R).
