Subsistencia y movilidad de los cazadores-recolectores que ocuparon Cueva Traful I durante el Holoceno Medio y Tardío.

We present the results of the analysis from middle and late Holocene bone ensemble of Traful I cave (province of Neuquén, Argentina). Also, we discuss the subsistence and mobility of the hunter-gatherers and the seasonality of their occupations. The huntersgatherers societies that recurrently inhabited this site, exploited the guanaco as part of their subsistence practices. This way of live is widespread in the middle Holocene, in the ecotono and in the steppe, but always complemented with small game, mollusks, fish or vegetables. In the last 2.000 years the number of exploited species significantly increased with diversity. This phenomenon is due to the reduction of the home ranges mostly drive by territorial circumscription of the groups that began to differ interethnically. The incorporation of the ceramic technology allowed: delay the consumption of some resources, extract the fat of the bones more efficiently and vegetables processing. These materials conditions of existence are interrupted by the Spanish conquest. Following this, the adoption of the horse radically changed the way of life of those pedestrian huntergatherers.
