Data associated with " Effects of intraspecific phenotypic variation on species coexistence" by Stephen Hausch, Steven M. Vamosi, and Jeremy W. Fox, published in the journal Ecology. Questions regarding these data can be directed to Jeremy W. Fox, jefox@ucalgary.ca, so long as he's still alive, email is still a thing, and that email address still works. The data file is a .csv file containing the results of the mutual invasibility trials. The variables are: resident: the identity of the resident population, abbreviated in the associated publication. CH denotes the high diversity population of C. chinensis, MH denotes the high diversity population of C. maculatus. invader: the identity of the invader population, abbreviated in the associated publication. CH denotes the high diversity population of C. chinensis, MH denotes the high diversity population of C. maculatus. replicate: identifier of the replicate for each treatments. In treatments with one replicate, it was designated replicate "a". In treatments with two replicates, they were designated "a" and "b". In treatments with 3 or 5 replicates, the replicates were numbered. M0: number of C. maculatus individuals in generation 0 C0: number of C. chinensis individuals in generation 0 M1: number of C. maculatus individuals in generation 1 C1: number of C. chinensis individuals in generation 1 M2: number of C. maculatus individuals in generation 2 C2: number of C. chinensis individuals in generation 2 M3A: number of C. maculatus individuals emerging from adzuki beans in generation 3 M3L: number of C. maculatus individuals emerging from lentils in generation 3 C3A: number of C. chinensis individuals emerging from adzuki beans in generation 3 C3L: number of C. chinensis individuals emerging from lentils in generation 3
