Table 1. Best models describing whether beekeepers multiply colonies, sell colonies or sell honey.

Response N Model Interpretation
Fixed effects Random effects
Multiplies colonies? 203 Number of colonies, Meliponiculture course, Native vegetation, and Supplementary feeding Main species Colony multiplication is more frequent among beekeepers that have more colonies, did a course in meliponiculture, keep their bees within 3 Km of native vegetation, and feed their colonies. These trends hold across the main species kept.
Sells colonies? 206 Sells honey?, Number of known beekeepers, and Supplementary feeding Main species Selling colonies is more frequent among beekeepers that sell honey, know a larger number of other beekeepers, and feed their colonies. These trends hold across the main species kept.
Sells honey? 198 Sells colonies?, Years keeping bees, Meliponiculture course, Education level, Crops, and Property type Main species Selling honey is more frequent among beekeepers that sell colonies, have more years of experience keeping bees, did a course in meliponiculture, have a lower level of education, have crops on their property, and have a rural property. These trends hold across the main species kept.

The number of observations included in each model is provided (N) along with the model structure and its biological interpretation. All models are generalized linear mixed models (GLMM) with a Bernoulli distributed response variable (logistic regressions). Regression coefficients, p-values, and confidence intervals for all models are summarized in S5 Table.
