本文报道了来自不同地理环境的5个现代种群的红鹿骨胶原（154头）的碳、氮稳定同位素比值。鹿之间没有显着差异，观察到占用森林和非森林环境受到类似的气候条件，表明一个简单的“冠层效应”没有观察到。平均种群δ 13 C与温度呈负相关，而平均种群δ 15 N与温度呈正相关。鹿年龄和胶原蛋白δ 13 C值之间存在微弱但显著的正相关性，来自朗姆酒岛种群（苏格兰）。种群内同位素变异的数量在种群之间并不一致;因此，现代食物网研究、古饮食基线数据和古生态学研究需要每个物种大量的个体。
C and N stable isotope ratios of red deer (Cervus elaphus) bone collagen (154 individuals) from five modern populations occupying geographically different habitats are reported. No significant difference was observed between deer occupying forested and non-forested environments subject to similar climatic conditions suggesting a simple “canopy effect” is not observed. Mean population δ13C is negatively correlated with temperature whereas mean population δ15N is positively correlated with temperature. A weak but significant positive correlation was observed between deer age and collagen δ13C values from the Isle of Rum population (Scotland). The amount of intra-population isotope variability is not consistent among populations; thus significant numbers of individuals from each species are required for modern food web studies, for palaeodietary baseline data, and for palaeoecological studies.
