对巴西南部高地晚全新世环境和文化序列的研究表明，Taquara/ itarar<s:1>人对该地区的殖民与该地区湿润气候条件导致的Araucaria森林的扩张有关，这种扩张始于约1410至900 cal. yr BP之间。人类在这一地区更密集和永久的占领与Araucaria森林的发展有关，这为Taquara/ itarar<s:1>群体提供了新的丰富和可靠的资源：Araucaria种子。此外，我们回顾了与该地区粮食生产开始相关的景观转变的证据。木炭记录显示，从全新世晚期开始，当地人口可能在较低海拔地区进行刀耕火种农业，并在全新世晚期的下半部分继续这种做法。
Abstract An examination of the late Holocene environmental and cultural sequences of the southern Brazilian highlands indicates that the colonisation of this region by the Taquara/Itararé people is associated with the expansion of Araucaria forest resulting from the onset of wetter climatic conditions in the region, which started between around 1410 and 900 cal. yr BP. The more intense and permanent human occupation of this region is associated with the advance of Araucaria forest, which provided Taquara/Itararé groups with a newly abundant and reliable resource: Araucaria seeds. In addition, we review the evidence for landscape transformation associated with the beginning of food-production in the region. Charcoal records show that local populations may have practiced slash-and-burn agriculture at lower elevations since the beginning of the late Holocene around 4320 cal. yr BP, and continued this practice during the second part of the late Holocene.
