All life span (LS) data is given in days from the time of hatching. Maximum life span (Max LS) refers to the mean of the longest-lived 10% of each test group. Brood size indicates average total number of offspring produced per individual adult hermaphrodite (C. elegans) or female (C. remanei) and is shown as average ± standard error. P-value is the result of a Wilcoxon Rank-Sum test of control fed versus BD survival for each strain.
