paleobotanical data from pollen cores is summarized in Chapter 3. However, the phase boundaries cannot be correlated with changes in material culture and include a notable gap from 4000 to 1200 cal BC, and future research is clearly needed to refine the region’s chronology. A second area where Walker’s work reveals the need for more research in Mojos concerns demographic estimates. A large majority (39 of 51) of forest islands that have been surveyed by archaeologists since 1996 show evidence of pre-Columbian occupation. The sizes of forest islands, and their spatial relationships with groups of raised fields, are used to roughly calculate a regional population between 10,000 and 100,000. However, this masks the problematic, or at least critically unexamined, assumptions about the contemporaneity and duration of the use (perhaps unavoidable at this early stage of our understanding of this region’s complex history) of both agricultural features and, to a lesser extent, domestic remains, coupled with inherent difficulties in dating natural and agricultural features. As Walker rightly notes, much work remains to be done in this area.

第 3 章总结了来自花粉核的古植物学数据。然而，相界不能与物质文化的变化相关联，并且包括公元前 4000 到 1200 卡的显着差距，未来的研究显然需要完善该地区的年表。Walker 的工作揭示了需要对 Mojos 进行更多研究的第二个领域涉及人口统计估计。自 1996 年以来，考古学家调查的大部分森林岛屿（51 个中的 39 个）都显示出哥伦布前占领的证据。林岛的大小，以及它们与高地群的空间关系，用于粗略计算10,000到100,000之间的区域人口。然而，这掩盖了有问题的，或者至少是未经严格审查的，关于使用农业特征和在较小程度上使用国内遗迹的同时期和持续时间的假设（在我们理解该地区复杂历史的早期阶段可能是不可避免的），加上在确定自然和农业特征方面存在固有困难。正如沃克正确指出的那样，这方面还有很多工作要做。
