Table 3.
Summary of top generalized dissimilarity models explaining genetic distances in devils, all DFTD tumors, and DFTD clusters separately. % deviance explained refers to the reduction in model deviance relative to the null. % model deviance explained refers to the percent change in model deviance upon permutation of a given variable.
