Abstract
INTRODUCTION The archaeology of the mid and late Holocene of the Rio de la Plata Basin (hereafter LPB) and its adjacent littoral Atlantic coast has received a new impetus in [...]
In this article, we focus on three case studies, which show how the climatic fluctuations that took place during the mid and late Holocene had a major impact on the native groups that inhabited the La Plata Basin region. First, we summarized the archaeological and the paleoenvironmental records of the mid-Holocene related to the emergence of "Constructores de Cerritos" in south-eastern Uruguay. Then, we review the evidence for a late Holocene more intense occupation of the southern Brazilian Highlands by the southern proto-Je groups and its association to the expansion of mixed Araucaria forest in this region. After that, we review the evidence for sea-level fluctuations and changes in settlement patterns of the mid and late-Holocene Sambaqui people that lived along the Atlantic coast of south-eastern Brazil. Finally, we briefly discuss the implications of these environmental changes for the development and dynamics of these cultures in the La Plata Basin region. Keywords: Landscape, Archaeobotany, Palaeoecology, La Plata basin. Neste artigo vamos abordar tres estudos de caso, avaliando como as variacoes climaticas que aconteceram durante o Holoceno medio e tardio produziram grandes impactos sobre as populacoes nativas que habitavam a regiao da Bacia do Prata. Primeiramente, e apresentado um resumo dos registros arqueologicos e paleoambientais do Holoceno medio relacionados com a emergencia das sociedades de "Construtores de Cerritos" no Sudeste do Uruguai. Em seguida, sao revisadas as evidencias da mais intensa ocupacao humana nas terras altas do sul do Brasil, pelos grupos proto-Je do Sul, e a associacao destes com a grande expansao da floresta de Araucaria nesta regiao, durante o Holoceno tardio. Depois disto, resumimos as relacoes entre as flutuacoes do nivel do mar e as mudancas no padrao de assentamento dos grupos sambaquieiros ao longo da costa do Atlantico, no sul brasileiro durante o Holoceno medio e tardio. Por ultimo, e apresentada breve discussao sobre as implicacoes destas mudancas ambientais no desenvolvimento e dinamicas destas culturas na regiao da Bacia do Prata. Palavras-Chave: Paisagem, Arqueobotanica, Paleoecologia, Bacia do Prata.
