Dataset4_Fattyacids.csv

Description

The dataset contains the fatty acid content and ratios for the two bumblebees. Measures are taken only from pollen from the leg-baskets. SampleID is not the same as in the metabarcoding, several samples from different bumblebees were merged within a Location ,Landscape and Replica. Not for all the samples there is information on both amino acids and fatty acids. The columns are:

• SampleID_chemical: The ID for chemical analyses
• Location: the three Swiss cantons studied. Levels: Bern =BE; Basel = BS; Zurich =ZH
• Landscape: the two typea of human-dominated ecosystems, nested to the Swiss canton. Levels: Urban = U; Rural = R
• Replicate: sampling place (800-m buffer) nested with the location and the landscape. Levels: A-E.
• Bumblebee_species: the two studied species, levels: B.pasquorum; B. lapidarius
• LocationLandscape: combination between location and landscape
• Caprylic, Pelargonic, ..., Lacceroic: Content of individual fatty acids acids.
• sum: total sum of fatty acid content (mg)
• unsaturatedsum: total sum unsaturated fatty acids (mg)
• saturatedsum: total sum saturated fatty acids (mg)
• omega3sum: total sum Omega 3 fatty acids (mg)
• omega6sum: total sum Omega 6 fatty acids (mg)
• omega9sum: total sum Omega 9 fatty acids (mg)
• omega6to3ratio: ratio Omega 6 to Omega3 fatty acids -saturatedtounsaturatedration: ratio between saturated and unsaturated fatty acids
