The documented quality of the zooarchaeological remains found in sambaquis is an important issue for ecologists who increasingly consider this material as a possible record of historical biodiversity to extend the observation periods of their analyses. In this work ichthyological inventories based on zooarchaeological remains were used to test the hypothesis that they do not differ statistically from those constructed by sampling current ichthyological diversity. Ichthyological records of 68 sambaquis of the Brazilian southeast coast were systematised. Data analyses were done based on taxa richness, taxonomic distinctness and food guild composition approaches. All analyses failed to show significant differences between sambaqui and modern fish inventories. Such result was kept for all tested scales and for the different studied regions. The current results indicate that sambaquis contain records of past species composition and therefore of Holocene biodiversity. It is concluded that sambaqui zooarchaeological remains should not be neglected in ecological studies and represent a quality alternative to extend the temporal scale of these studies.

sambaquis（贝壳丘）可以用作全新世海洋鱼类生物多样性的记录吗？

对于生态学家来说，在桑巴奎人发现的动物考古遗迹的质量记录是一个重要的问题，他们日益将这种材料视为历史生物多样性的可能记录，以延长其分析的观察期。在这项工作中，基于动物考古学遗迹的鱼类学调查清单被用于检验以下假设：它们与从目前的鱼类学多样性采样得出的统计数据没有统计学差异。系统记录了巴西东南沿海68条桑巴人的鱼类学记录。数据分析基于分类单元丰富性，分类学独特性和食品行会组成方法进行。所有分析均未能显示出桑巴奎鱼种群与现代鱼类种群之间的显着差异。对于所有测试的量表和不同的研究区域，都保留了这样的结果。目前的结果表明，桑巴奎人包含过去物种组成的记录，因此也包含全新世生物多样性的记录。结论是，在生态学研究中不应忽略桑巴基动物考古学遗迹，并且可以作为扩展这些研究时间范围的一种质量替代方法。
