Carbon and nitrogen stable isotopes of reindeer (Rangifer tarandus) bones from three Norwegian modern wild reindeer populations (Setesdal Ryfylke, Hardangervidda and Rondane) were used to investigate variations in δ¹³C and δ¹⁵N between, and within, populations. Each of these reindeer populations lives in different climatic and environmental conditions, thus vegetation and climatic conditions could be linked to their stable isotopic signature. Reindeer bones from several archaeological sites on Hardangervidda representing three chronological ranges (275–350 CE, 11th, and 13th century CE) were then analysed for their stable isotopic composition. No statistically significant differences were found within the populations, but the stable isotopic values differed between populations. Subsequently, these stable isotopic values were used to infer modern climatic conditions to sub-fossil palaeoenvironmental conditions on Hardangervidda.

驯鹿（碳和氮的稳定同位素驯鹿）从三个挪威现代化的野生驯鹿种群（Setesdal吕菲尔克，Hardangervidda和龙达讷）骨头被用于研究δ变化¹³ C和δ ¹⁵人口之间和人口内部的N。这些驯鹿种群中的每一个都生活在不同的气候和环境条件下，因此植被和气候条件可能与其稳定的同位素特征有关。然后分析了Hardangervidda上代表三个时间范围（275-350 CE，11和13世纪CE）的几个考古遗址的驯鹿骨头的稳定同位素组成。在群体内未发现统计学上的显着差异，但群体间的稳定同位素值有所不同。随后，这些稳定的同位素值被用于推断哈当厄尔维达（Hardangervidda）亚化石古环境的现代气候条件。
