Mean discrimination factors ± SD (‰) between experimental diet and tissues of arctic foxes.

Subscripts: Sample sizes are within parentheses. ΔC are obtained after lipid correction (see details in methods). A: adult; F: female; M: male; Y: yearling;
*assuming that the delay since diet shift was long enough to exceed the turnover of both liver and muscle, following other estimates available from other mammals [5]. There was missing information for some individuals, which resulted in varying sample sizes in the different analyses or summary estimates.

下标说明：样本量标注于括号内。ΔC经脂质校正后得到（具体细节详见研究方法部分）。A：成年个体（adult）；F：雌性个体（female）；M：雄性个体（male）；Y：一岁龄个体（yearling）；
*本研究假设，自饮食转换以来的延迟时长已足够长，足以超过肝脏与肌肉组织的代谢周转周期，该假设参考了其他哺乳动物的已有研究估算结果[5]。部分个体存在信息缺失的情况，导致不同分析或汇总估算所采用的样本量存在差异。
