TL range is the range of total lengths of fish sampled from each species. For partial carcasses whereTL was unavailable, TL was predicted using linear regression of TL against head length (TL = 0.79 +3.225*Head Length; R2 = 0.94; P < 0.0001). To ensure that only adult fish were used in the analysiswe excluded specimens whose TL was below the TL at which 50% of that species is reproductivelymature (data in Love et al. 2002), or the age at first maturity if the former was unavailable.

these values were unavailable we used the rule of thumb that TL at maturity ≈ 50% of the species’maximum TL (Love et al. 2002).

PC1, PC2, and PC3 are scores from the principal component analysis of species mean trait values.δ15N values are species means of adjusted δ15N (refer to text for explanation). δ15N was onlydetermined for fish from sources 1, 2, or 3 (not for preserved specimens), and species with samplesizes > 10 (S. caurinus, S. melanops, and S. mystinus) were subsampled for δ15N analysis.
