Raw data of compounds extracted by GC-MS from each population replicate's of I. uriae ticks from Iceland.

Raw data representing all the compounds extracted by GC-MS from each population replicate’s of I. uriae ticks from three sites in Iceland. Each replicate contain a pool of 10 living flat female ticks.

Site: name of the site where ticks were collected.

Host: name of the host bird.

Replicate: number of the replicate (1 to 4).

Peak: number of the detected peaks correponding to extracted compounds.

Retention Time: time elapsed between sample introduction and the maximum signal of the given compound.

Area: area under the curves of each detected coumpounds on the chromatogram.
