The carbon to nitrogen ratio and stable isotope signatures of penguin chick feathers and nine common krill and fish prey species.

Carbon to nitrogen ratios (C/N) and stable isotope values (δ15N & δ13C) are presented mean ± SD. Chick feathers and prey species that do not share at least one superscript within a column for each group (feathers or prey) are significantly different for the variable in question at the 0.05 level. P. bolini[45] and C. gunnari[44] were not included in prey species analyses.

本数据集展示了碳氮比（C/N）与稳定同位素比值（δ15N、δ13C）的平均值±标准差。针对每组（雏鸟羽毛组或猎物组）的每一列，若其中的雏鸟羽毛与猎物物种未共享至少一个上标，则二者对应的目标变量在0.05显著性水平下存在显著差异。P. bolini[45]与C. gunnari[44]未被纳入猎物物种分析。
