我们目前的硫同位素比测量骨胶原从动物（n = 75）和人类（n = 120）从五个网站可追溯到四个年代（铜石器时代，迦太基，古代晚期-早期拜占庭，伊斯兰教）从巴利阿里群岛的伊维萨岛和福门特拉岛，西班牙。本研究是对先前发表的δ（13）C和δ（15）N值的后续研究[Fuller等人：Am J Phys Anthropol 143（2010）512-522]，并专注于使用δ（34）S值来更好地了解这些人群随时间的饮食模式，并可能识别这些岛屿的移民。动物的δ（34）S值范围（10.5-17.8‰）相对较宽，这表明显著的海水喷洒效应使福门特拉岛和伊维萨岛的土壤中增加了海洋硫酸盐。不同人群的平均δ（34）S值分别为：铜石时代（16.5 ± 1.4‰）、迦太基乡村（13.6 ± 1.7‰）、迦太基城市（12.9 ± 1.8‰）、古代晚期-拜占庭早期（12.3 ± 2.1‰）和伊斯兰（9.1 ± 2.7‰）。这些人类δ（34）S结果与动物数据相似，这一发现支持了这些社会几乎没有海洋蛋白质消费的观点，并且饮食主要基于陆地资源。在迦太基和古代晚期-早期拜占庭时期，δ（34）S值被用来识别人口中可能不是在岛上出生或长大的人。此外，在20名伊斯兰时期的人中，有18人的δ（34）S值表明他们是伊维萨岛的移民，在获得新的当地硫同位素特征之前就去世了。
We present sulfur isotope ratio measurements of bone collagen from animals (n = 75) and humans (n = 120) from five sites dating to four chronological periods (Chalcolithic, Punic, Late Antiquity-Early Byzantine, and Islamic) from the Balearic Islands of Ibiza and Formentera, Spain. This study is a follow up to previously published δ(13)C and δ(15)N values by [Fuller et al.: Am J Phys Anthropol 143 (2010) 512-522] and focuses on using δ(34)S values to better understand the dietary patterns of these populations through time and to possibly identify immigrants to these islands. The range of δ(34)S values (10.5-17.8‰) observed for the animals was relatively broad, which suggests that a significant sea spray effect has added marine sulfates to the soils of Formentera and Ibiza. The mean δ(34)S values of the different human populations were found to be: Chalcolithic (16.5 ± 1.4‰), Punic rural (13.6 ± 1.7‰), Punic urban (12.9 ± 1.8‰), Late Antiquity-Early Byzantine (12.3 ± 2.1‰), and Islamic (9.1 ± 2.7‰). These human δ(34)S results are similar to the animal data, a finding that supports the notion that there was little marine protein consumption by these societies and that the diet was mainly based on terrestrial resources. During the Punic and Late Antiquity-Early Byzantine periods the δ(34)S values were used to identify individuals in the population who likely were not born or raised on the islands. In addition, 18 of the 20 individuals analyzed from the Islamic period have δ(34)S values that indicate that they were immigrants to Ibiza who died before acquiring the new local sulfur isotopic signature.
