Correction to: ‘Mobile marine predators: an understudied source of nutrients to coral reefs in an unfished atoll’

There were two errors in our original submission: (i) an error in the equation used to calculate egested nitrogen, ultimately leading to a small (1.8%) reduction in our estimate of nitrogen egestion; and (ii) an omitted step in converting wet weight of ingested material to dry mass, leading to a further approximately 50% reduction in the estimate of nitrogen egestion at the individual and population level. In the nitrogen egestion equation, N was used to define two different variables, and the second N was incorrectly defined and assessed as the percentage concentration of nitrogen found in the grey reef shark tissue, for which we used 14.84% (unpublished data from McCauley et al. [5]). We have rewritten the equation (below) and updated the relevant term to correctly represent the per cent of nitrogen found in the prey species, for which we used 13.0% for the Pacific mackerel (Scomber japonicus) [4]. The rate of nitrogen egested by an individual i grey reef shark per day (EN) was defined as EN,i 1⁄4 Ii (1 b) Nprey, ð1Þ
