Shellmounds of different sizes and characteristics mark the landscape along the Southern and Southeastern Brazilian coast, attesting to a multimillennial occupation that is dated from at least 8500 until 1000 calibrated years before present. Their builders are currently recognized as fisher-gatherers, and until quite recently plants were thought to represent only a minor part of their diet. However, evidence of wild and domesticated plant remains obtained from diverse proxies across sites, contexts, and chronologies point to a different scenario. The importance of a variety of tubers, fruits, and seeds, including yam, sweet potato, leren, squash, and maize has been documented. The evidence demonstrates that shellmound builders subsisted in a system of mixed economy, where fishing and gathering were associated with horticulture. They modified the landscape, tended home gardens, and exploited substantial amounts of tuberous crops. This paper discusses the significance of plant remains to a low-level food production system while contextualizing them over the landscape.

不同大小和特征的贝壳冢标志着巴西南部和东南部沿海地区的景观，证明了其千年发展历程，其历史可追溯到至少8500年至经过校准的1000年之前。他们的建设者目前被认为是捕捞者，直到最近，人们还认为植物仅占其饮食的一小部分。但是，野生和驯化植物的证据仍然可以从跨地点，环境和年代的不同代理获得，这表明情况有所不同。各种薯，水果和种子（包括山药，甘薯，小菜，南瓜和玉米）的重要性已被记录。证据表明，炮弹建造者生活在混合经济体系中，渔业和捕捞与园艺相关。他们修改了景观，养育了家庭花园，并利用了大量的块茎作物。本文讨论了植物遗骸对低级食品生产系统的重要性，同时将其遗留在整个景观中。
