Fig. 5: Spatiotemporal patterns in Adélie penguin (Pygoscelis adeliae) diet.

A Relative proportions of krill (Euphausiaceae), fish (Actinopteri), and cnidarian reads for each sample based on LCA analysis. Sites are arranged by age groupings, and within these by latitude (north to south). Samples at each site are shown in stratigraphic order; (B) ratios of fish:krill reads for each site, arranged by latitude (north to south). Boxplot elements are median (solid line), interquartile range (grey box), minimum and maximum values excluding outliers (whiskers) and outliers (circles). Italicised numbers refer to the number of samples yielding fish and krill DNA at each site. C Antarctic fish assemblages recovered from southern Ross Sea sites. Sites are ordered from youngest to oldest based on calibrated radiocarbon ages obtained in this study (Supplementary Table 1).
