When and why humans chose to depart mainlands in favor of islands are fundamental questions asked by anthropologists. Decision-making is shaped by issues still faced today, such as intra- and inter-group conflict or environmental conditions. Prehistoric archaeological deposits are particularly well suited to examining the incipient colonization of island landmasses, as well as the nature of early habitation, because they typically offer the first and only physical records of past human activity. Within a broader context of island settlement and use, Ryan Harke will study native fisher-gatherer populations who inhabited the only subtropical small-island ecosystems in North America. This research project will also have specific outcomes relating to public interest, including pre-modern seawater temperature data and new interpretive signage to educate visitors on the cultural and environmental history of the region. Scientific evidence demonstrates that tropical archipelagoes are the sum of interconnected terrestrial, nearshore, and pelagic habitats, many of which provided suitable marine subsistence resources, shelters, and trading grounds throughout human history. Thus, the archaeology of "marginal" small-island ecosystems offers the foundation to model human lifeways at and journeys to such places across the globe, and compare culturally and/or biologically distinct populations. This research will focus on the historical, ethnohistorical, and zooarchaeological datasets of the island of Key West, to determine when prehistoric Native Americans reached the island, and whether they constructed year-round villages there. These questions will be addressed using a method similar to dendrochronology (the study of tree rings) called sclerochronology. Using this technique on modern clam shells and those discarded by ancient peoples will reveal annual cycles of seawater temperature and salinity contained in their isotopic (geochemical) signatures, indicating season of habitation. By sampling a large collection of midden shells and evaluating the seasonality of other associated animal remains, this research will determine whether a fishing economy could be based on freshwater-deficient coral islands year-round. The Keys are a vital case study for worldwide colonization models in human island biogeography, as their indigenous peoples offer a rare circumstance of non-agricultural groups relocating to small islands.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

人类何时以及为何选择离开大陆前往岛屿，是人类学家提出的基本问题。决策是由当今仍然面临的问题决定的，例如群体内部和群体间的冲突或环境条件。史前考古沉积物特别适合研究岛屿陆地的早期殖民以及早期居住的性质，因为它们通常提供过去人类活动的第一个也是唯一的物理记录。在更广泛的岛屿定居和利用背景下，瑞安·哈克将研究居住在北美唯一的亚热带小岛屿生态系统中的当地渔民和采集者群体。该研究项目还将产生与公共利益相关的具体成果，包括前现代海水温度数据和新的解说标牌，以教育游客了解该地区的文化和环境历史。科学证据表明，热带群岛是相互关联的陆地、近岸和远洋栖息地的总和，其中许多在整个人类历史上提供了合适的海洋生存资源、庇护所和贸易场所。因此，“边缘”小岛屿生态系统的考古学为模拟全球这些地方的人类生活方式和旅程提供了基础，并比较了文化和/或生物上不同的人群。这项研究将重点关注基韦斯特岛的历史、民族历史和动物考古数据集，以确定史前美洲原住民何时到达该岛，以及他们是否在那里建造了全年开放的村庄。这些问题将使用类似于树木年代学（树木年轮的研究）的方法来解决，称为硬化年代学。在现代蛤壳和古代人们丢弃的蛤壳上使用这种技术将揭示其同位素（地球化学）特征中包含的海水温度和盐度的年度循环，从而表明居住的季节。通过对大量贝壳进行采样并评估其他相关动物遗骸的季节性，这项研究将确定渔业经济是否可以以全年缺乏淡水的珊瑚岛为基础。这些岛屿是人类岛屿生物地理学中全球殖民模型的重要案例研究，因为其土著人民为非农业群体迁移到小岛屿提供了罕见的环境。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准。
