Lonsdorf_etal_2023_ObservedPredicted_exposure

These data include observed pesticide residues in pollens gathered by bumble bees (Bombus vosnesenskii) returning to colonies across 14 spatially independent landscapes in Northern California. These data were used to evaluate a spatially explicit model of landscape exposure that was parameterized with 6 different specifications with regards to floral resources, pesticide accumulation, and foraging behavior. The associated paper has been been published as an article in Science of the Total Environment. The columns are:
FID - Field Identifier for the 14 sites used in this analysisYear - This study took place in 2017Round - Collection rounds for pollen samples. Pollen loads from the two colonies at a site and for two consecutive sample rounds were pooled (from 10- and 20-days past field placement, 30- and 40-days, etc.)Compound - Name of pesticide detectedPesticide_type - either fungicide, herbicide, or insecticideModelNumber - Different exposure model specifications . See Methods and Table 1 in Lonsdorf et al. 2023 Sci. Tot. Env.ModelSpecifications - shorthand abbreviations of different specifications . See Methods and Table 1 in Lonsdorf et al. 2023 Sci. Tot. Env.Modeled_exposure - predicted exposure value for a given combination of site, round, compound, and specification.Concentration_ng_mg - observed pesticide residue (ng/mg) for a given a given combination of site, round, and compound.Citing information:
