理由
估算组织和食物之间的稳定同位素偏移对于食物重建是重要的。虽然黑猩猩（Pan troglodytes）的稳定同位素研究越来越多，但黑猩猩的同位素偏移从未被研究过。本研究首次测定了13只圈养黑猩猩毛发和粪便中碳、氮稳定同位素偏移值。
方法
记录每只动物1周内所有消耗的食物项目和数量。食物样品通常收集三次，在实验周后3周收集毛发，并且在实验周期间随意收集粪便。利用元素分析-同位素比值质谱法（EA-IRMS）测定了稳定碳、氮同位素比值。
结果
根据Monte Carlo分析的结果，对于95%置信区间（CI），毛发和饮食之间的碳和氮补偿估计值分别为+3.0至+3.9‰和+2.8至+3.7‰。粪便和饲料之间碳和氮补偿值的95%CI分别为-1.6 ‰至0.0‰和+1.2 ‰至+2.7‰。
结论
这些偏移值与先前研究中报告的其他灵长类物种的偏移值基本一致。然而，由于饮食和生理因素的偏移值的潜在变化应在未来详细研究。版权所有© 2016约翰威利父子有限公司.
RATIONALE
Estimation of the stable isotopic offsets between tissue and diet is important for dietary reconstructions. Although stable isotopic studies of chimpanzees (Pan troglodytes) are increasing, the isotopic offsets in chimpanzees have never been studied. In this study, the carbon and nitrogen stable isotopic offset values in hair and feces were measured for 13 captive chimpanzees for the first time.
METHODS
All consumed food items and quantities were recorded for each individual for 1 week. Food samples were typically collected three times, hair was collected 3 weeks after the experimental week, and feces were collected ad libitum during the experimental week. The stable carbon and nitrogen isotope ratios were measured using elemental analyzer-isotope ratio mass spectrometry (EA-IRMS).
RESULTS
As the results of Monte Carlo analysis, the estimated carbon and nitrogen offsets between the hair and diet were +3.0 to +3.9‰ and +2.8 to +3.7‰, respectively, for the 95% confidence intervals (CIs). The 95% CIs of the carbon and nitrogen offset values between the feces and diet were -1.6 to 0.0‰ and +1.2 to +2.7‰, respectively.
CONCLUSIONS
These offset values are generally consistent with those of the other primate species reported in previous studies. However, potential variations in the offset values due to dietary and physiological factors should be studied in detail in the future. Copyright © 2016 John Wiley & Sons, Ltd.
