Paleoethnobotanical perspectives are essential for understanding past lifeways yet continue to be underrepresented in Paleoindian research. We present new archaeobotanical and radiocarbon data from combustion features within stratified cultural components at Connley Caves, Oregon, that reaffirm the inclusion of plants in the diet of Paleoindian groups. Botanical remains from three features in Connley Cave 5 show that people foraged for diverse dryland taxa and a narrow range of wetland plants during the summer and fall months. These data add new taxa to the known Pleistocene food economy and support the idea that groups equipped with Western Stemmed Tradition toolkits had broad, flexible diets. When viewed continentally, this work contributes to a growing body of research indicating that regionally adapted subsistence strategies were in place by at least the Younger Dryas and that some foragers in the Far West may have incorporated a wider range of plants including small seeds, leafy greens, fruits, cacti, and geophytes into their diet earlier than did Paleoindian groups elsewhere in North America. The increasing appearance of diverse and seemingly low-ranked resources in the emerging Paleoindian plant-food economy suggests the need to explore a variety of nutritional variables to explain certain aspects of early foraging behavior.

古民族植物学观点对于理解过去的生活方式至关重要，但在古印度研究中的代表性仍然不足。我们提供了来自俄勒冈州康利洞穴分层文化成分中燃烧特征的新的考古植物学和放射性碳数据，这些数据重申了植物在古印第安人群体的饮食中的加入。康利洞穴 5 中三个特征的植物遗骸表明，人们在夏季和秋季月份为不同的旱地分类群和范围狭窄的湿地植物觅食。这些数据为已知的更新世食品经济增加了新的分类群，并支持了配备西方茎传统工具包的群体具有广泛、灵活饮食的观点。从大陆看，这项工作有助于越来越多的研究表明，至少年轻的仙人掌已经制定了适合区域的生存策略，并且远西部的一些觅食者可能已经吸收了更广泛的植物，包括小种子、绿叶蔬菜、水果、仙人掌，并且地球植物比北美其他地方的古印度人群体更早地进入他们的饮食。在新兴的古印度植物食品经济中，多样化且看似低级的资源越来越多地出现，这表明需要探索各种营养变量来解释早期觅食行为的某些方面。和地球植物比北美其他地方的古印度人群体更早地进入他们的饮食。在新兴的古印度植物食品经济中，多样化且看似低级的资源越来越多地出现，这表明需要探索各种营养变量来解释早期觅食行为的某些方面。和地球植物比北美其他地方的古印度人群体更早地进入他们的饮食。在新兴的古印度植物食品经济中，多样化且看似低级的资源越来越多地出现，这表明需要探索各种营养变量来解释早期觅食行为的某些方面。
