Results of a Redundancy Analysis (RDA) performed on the concentrations of pesticides in pollen, and the proprtion of pollen from the dominant taxa (i.e., more than 1% in at least one nest) in the studied 12 nests of Osmia bicornis in the agricultural landscape. Positions of the vectors of dependent variables on the two first RDA axes are shown by black arrows and that of the independent variables (proportion of pollen taxa) are shown by red arrows. The first ordination axis explained 29.1% of the variance of the dependent variables and the second 25.0%.
