Local Adaptation

Local adaptation data. Fecundity of hosts from the Co-passaged treatment paired with sympatric and allopatric parasites from the Co-passaged treatment. A “1” in the “Sympatric” column indicates a sympatric pairing; “0” indicates allopatric. “Line_host” and “Line_parasite” indicate the replicate lineages of host and parasite, respectively, combined in the assay. “Replicate” identifies the 15 hermaphrodites assayed for fecundity per pairing. The number of offspring produced by each hermaphrodite is reported in the column “Offspring.”
