There was an error published in J. Exp. Biol. (2016) 219, 3896-3906 (doi:10.1242/jeb.146381).

In Table S1, some of the values were incorrectly assigned to tank treatments and were averaged over an incorrect period that did not correspond to the number of days from the beginning to the end of the experiment. This error does not affect the conclusions of the experimental work, and the values have been corrected in the current version of Table S1.

The authors apologise for any inconvenience this may have caused.
