Theoretical dose-response relationship between marine debris and seabird death. This model is adapted from Wilcox et al.14. We assigned each seabird death into three cause of death categories: (1) known, non-debris ingestion related (KND), where there was a clearly identifiable cause such as drowning as fisheries by-catch; (2) indeterminate (Ind), where there was marine debris present in the gut but also other possible causes, such as starvation and (3) known, marine debris ingestion related (KD), where there was a gut blockage, or other strong evidence of the ingested debris being the cause of mortality.
