aA population is defined by location and lineage. The number of individuals per population varies between 8 and 10. The altitude and the nematode lineage isolated from each location are shown. For a more detailed list of P. pacificus strains used in this study, see electronic supplementary material, table S1.
bAtmospheric oxygen partial pressure given in kPa (see Methods).
cAmbient oxygen level calculated as a percentage of sea-level value. Note that at 2150 m.a.s.l., the oxygen available for respiration is 22% lower than at sea level.
