Population Dynamics and Human Strategies in Northwestern Patagonia

In this paper we evaluate the role of human strategies in Andean Piedmont from northern Patagonia across Holocene. Specifically, present analysis Early Holocene-Late Holocene archaeological record Salamanca cave (Mendoza-Argentina). We identified technological changes that occurred during Late and implications a occupation hiatus Middle follow multiproxy approach by radiocarbon dates, archaeofaunal remains, ceramic, lithics XRF obsidian sourcing. also discuss detailed stratigraphic sequence geomorphological descriptions, construction model summed probability distributions, compared with other sites region. conclude after hiatus, populations grew while guanaco dropped. The imbalance between demography resources boosted incorporation new technologies such as ceramics bow arrow, allowing people to exploit lower-ranked resources.
