Table 2 Results from the partial canonical model including spatial variables to control pseudoreplication linked to experimental design (see statistical methods). Variation partitioning quantifies the proportion of variation explained by sample type, sampling time and variables (site, apriary, hive) on the plant genera found in samples of honey (n = 97) and beebread (n = 87), collected from 43 hives in 6 apiaries in Finland in 2021.
