Paleoenvironments and use of wood resources by hunter-gatherers of Northeastern Patagonia since the middle holocene

Environmental changes occurred during Mid-Late Holocene have had influence over the availability of resources and the Patagonian hunter-gatherer strategies on environment use. In this sense, the interaction between landscape heterogeneity, climatic conditions and use of resources by human occupation...

The greatest selection pressure by taxa as Condalia sp. and Chuquiraga sp. could be linked to cultural issues, such as fuel selection patterns, and in the case of Prosopis sp. the availability of resources determined by paleoenvironmental conditions.
