Mean migration speed following fusion. Two groups of 10 large plasmodia of two different ages, 5 (young) and 54 (very old) weeks old, were used to conduct this experiment. Before the migration speed assays, slime moulds were allowed to fuse either with a slime mould of the same age or with a slime mould of a different age. The substrates were made of oat gel 5% w/v (oat). N = 100 for each pair type (young/young, young/old, old/old). Total number of assays = 600. Error bars indicate 95% CI. (Online version in colour.)
