Table 2 in Clonal mechanisms that matter in Agave fourcroydes and A. sisalana invasions in drylands: implications for their management

Table 2. Standardized coefficients of the best-fitting Generalized Linear Mixed Models (GLMMs) explaining bulbil rooting success under the monitored conditions (natural conditions, and experimental plots). Three predictor variable types were considered (intrinsic mother plant and bulbil traits, and extrinsic bulbil traits). Species identity and plots were included as random factors. The best model was ranked according to AIC (Akaike Information Criterion) value (See also Table S5). Non-data cells indicate variables not included in a particular model.
