Modos de ocupación del bosque patagónico de la vertiente oriental de Los Andes: aportes desde la ecología isotópica

Abstract

In this paper we discuss the contribution of stable isotopes of carbon and nitrogen to the problemof human occupation of the forest on the eastern slope of the Andes. An initial characterization offorest isotopic ecology is presented on the basis of 58 plants and herbivores values and two humanvalues. It is possible to discriminate isotopic signals of forest resources and to assess the degree ofpermanence and / or intensity of use of forest in the past.
