RUI: Late Pleistocene Animal and Plant Associations and Extinctions on the Central Colorado Plateau

这是一项研究 动物和植物及其与地球的相互作用 更新世晚期和巨型动物灭绝时期 在科罗拉多高原。 中部两个学习区 将考察科罗拉多高原：四十英里峡谷 （主要包括BF Alcove和Grobot Grotto）和白色 峡谷（裸梯废墟）。 哺乳动物的药物（猛犸，cf. 骆驼，比照灌木牛、山羊、野牛等）， +39，000到11，000年。血压，将进行放射性碳分析 粒重比，粒级含量，花粉， 显微组织学和生化数据。 这些数据将提供 生产商标识、年龄和饮食。 独立 古环境重建将伴随着 沉积历史分析（23米的层状沉积物， 一个凹室），来自分层冲积层和洞穴沉积物的花粉 （区域和当地环境）和小栖鼠的粪坑 （宏化石;当地社区）。 多学科 这种方法将直接产生植物和动物数据， 彼此之间的联系。 灭绝的哺乳动物的食物 记录下来，就像他们在当地灭绝的时间一样。 北方亚利桑那大学将提供：1） J.I.米德（半时间学术）和L.D. Bilby（英语：The Bilby） 研究中心实验室设施，3）策展空间， 粪便和毛发遗骸，4）现代比较收藏， 粪便和毛发; 5）化学家D的工资。罗素，和6）a 现代有机化学实验室

This is a proposal to study the relationships between animals and plants and their interactions with the earth during the late Pleistocene and at the time of megafaunal extinctions on the Colorado Plateau. Two study areas in the central Colorado Plateau will be investigated: Forty Mile Canyon (containing principally BF Alcove and Grobot Grotto) and White Canyon (Bare Ladder Ruin). Drug of mammals (mammoth, cf. camel, cf. shrub-ox, mountain goat, bison, among others), dating +39,000 to 11,000 yr. B.P., will be analyzed for radiocarbon, size-weight ratio, size-fractional content, pollen, microhistology, and biochemical data. These data will provide producer identifications, age, and diet. Independent paleoenvironmental reconstruction will generated with the analysis of sedimentary history (23 m of stratified sediments in one alcove), pollen from stratified alluvium and cave sediments (regional and local environments), and packrat middens (macrofossil; local communities). The multidisciplinary approach will produce plant and animal data in direct association with each other. Diets of extinct mammals will be documented, as will the time of their local extinction. Northern Arizona University will provide: 1) the salary of J.I. Mead (half-time academic) and L.D. Agenbroad, 2) the Bilby Research Center laboratory facilities, 3) curatorial space for dung and hair remains, 4) modern comparative collections of dung and hair, 5) the salary for chemist D. Russell, and 6) a modern organic chemistry laboratory.
