Table 1.
Variables used for orchards and pollinators distribution modelling. The table shows the final set of predictors used to model the distribution of orchards (ODM) and pollinators (PDM). The selection of predictors was based on several criteria, including their use in published literature and minimizing multicollinearity

Isothermality = Mean diurnal range/Temperature annual range × 100. Isothermality quantifies how large is the day-to-night temperature oscillation in comparison to the summer-to-winter oscillation, with 100 representing a site where the diurnal temperature range is equal to the annual temperature range.
