Polllen preference score and interactions

This excel file contains the preference score of each bee species that is/will be modelled in ALMaSS. Each pollen score was calculated according to the following strategy: 1. Plant-pollinator interactions will set the baseline for the pollen preference. If a pollinator has never interacted with the plant species, a preference score of 0 is set and no further analysis is performed. If a pollinator interacts with a particular plant species, a score of 1 is assigned.2. The P:L ratio is then applied according to the literature data on pollinator preferences. If the P:L ratio is within the range of pollinator preferences, a score of 1 is added and the plant species will have a higher preference value (2). If not, it retains the same score as before (1).3. The minerals content is then used by giving preference to lower K:Na ratios. Taking into account the plant species visited by the pollinator (point 1), and that bees prefer to visit plants with a lower K:Na ratio, plant species with K:Na ratio lower than the mean are given a score of 1. Plant species with higher than the mean K:Na ratio do not receive any score. In the end, each plant species can have a score from 0 to 3, which determines the level of preference of the pollinator: 0 = no interaction, 1 = poorly preferred, 2 = moderately preferred and 3 = Strongly preferred.Since was not possible to use the nutritional approach for the other species that are being modelled (Eristalis tenax, Sphaerophoria scripta, Noctua pronuba and Pieris napi), the excel file only contains the presence/absence data of interactions.
