The graph shows the relationship between the chemical scent bouquet of lipids on bumblebees and important environmental parameters. Sites are shown as individual plots and ellipses for region groups (ALB: Schwäbische Alb, HAI: Hainich-Dün, SCH: Schorfheide-Chorin). The explanatory variables temperature and land-use intensity (LUI) are shown as red lines, the three scent compounds with the highest loadings in CAP1 and CAP2, namely (Z)-7-Pentacosene (Z7_C25), Pentacosane (C25), and Hentriacontane (C31), are shown as black lines.
