All listed studies were conducted at 20°C with E. coli OP50 as food source. Underlined values indicate lifespans determined in liquid media.
MYOB = Modified Youngren's only bactopeptone (solid); NGM = nematode growth medium (solid); S = S basal medium plus cholesterol (liquid); WI = wild isolates, other than N2; ^avalue interpolated from Figure 2; ^bvalues interpolated from Figs. 1A, 1C; ^cincludes time from egg deposition to hatching, see Table 1; ^dfecundity was assayed on NGM, survival in S medium; ^eE. coli B/r or OP50 used as food; ^fvalues interpolated from Figs. 2A, 2C.
