Abstract

Small islands are important model systems for examining the role of people in shaping novel environments and modifying resources through time. Here we report on the vertebrate faunal assemblages recovered from two sites on Ofu and Olosega islands (American Samoa), which were occupied only a few centuries after the initial settlement of the islands. We assess forager decision-making both locally and regionally as well as changing subsistence regimes. Our results suggest foraging efforts were focused on the marine environment, particularly fish, but with concomitant evidence for interactions with terrestrial habitats (e.g. seabirds) including the introduction of commensal species (i.e. red junglefowl and Pacific rat). Notably we documented a high degree of similarity between the fish species reported archaeologically and those targeted by modern subsistence fishers in the region, which is despite the occurrence of wide scale coastal landscape changes over the past several thousand years. These preliminary outcomes may suggest fish resources have remained stable through initial occupation to the present-day, but future zooarchaeological research is required to comprehensively evaluate the sustainability of the marine fishery over the past several millennia.

评估公元前一千年马努阿(美属萨摩亚)小岛屿上的觅食变化
小岛屿是研究人们在塑造新环境和随着时间改变资源方面的作用的重要模式系统。在这里,我们报告了从奥富岛和奥罗塞加岛(美属萨摩亚)的两个地点恢复的脊椎动物区系组合,这两个地点在最初的定居之后仅仅几个世纪就被占领了。我们评估了觅食者在当地和区域的决策,以及不断变化的生存制度。我们的研究结果表明,它们的觅食活动主要集中在海洋环境,尤其是鱼类,但同时也有证据表明它们与陆地栖息地(如海鸟)的相互作用,包括引入共生物种(如红丛林鸮和太平洋鼠)。值得注意的是,尽管在过去的几千年里发生了大规模的沿海景观变化,但我们记录了考古报告的鱼类与该地区现代自给渔民所瞄准的鱼类之间的高度相似性。这些初步结果可能表明鱼类资源从最初的占领到现在一直保持稳定,但未来的动物考古研究需要全面评估过去几千年来海洋渔业的可持续性。

期刊介绍: Archaeology in Oceania is published online and in print versions three times a year: April, July, October. It accepts articles and research reports in prehistoric and historical archaeology, modern material culture and human biology of ancient and modern human populations. Its primary geographic focus is Australia, the islands of the Pacific Ocean and lands of the western Pacific rim. All articles and research reports accepted as being within the remit of the journal and of appropriate standard will be reviewed by two scholars; authors will be informed of these comments though not necessarily of the reviewer’s names.
