El artículo analiza las subordinadas locativas y modales del tehuelche o aonek’o ?a?jen, lengua indígena de la Patagonia argentina hablada entre el río Santa Cruz y el Estrecho de Magallanes. Actualmente, se halla en un proceso avanzado de pérdida, aunque la comunidad tehuelche intenta revitalizarla. En el marco de la tipología funcional, se describen ambas cláusulas teniendo en cuenta el elemento que las introduce, su ubicación en la oración principal y el modo del núcleo predicativo. Asimismo, se consideran las similitudes existentes entre ambas. Por último, se explica el origen de los subordinantes y de las variantes que estos presentan. Para ello, se recurre a la comparación con el selknam, lengua perteneciente a la familia Chon, al igual que el tehuelche. / This article analyzes locative and manner clauses of the Tehuelche or Aonek’o ?a?jen, an indigenous language of the Argentinian Patagonia, spoken between the Santa Cruz river and the Strait of Magellan. At present, this language is facing an advanced process of extinction, despite Tehuelche community efforts to revitalize it. Locative and manner clauses are described according to a functional-typological frame, by taking into account the element that introduces them, their location in the sentence and the mood of the predicative core. In addition, the similarities found between both clauses are considered. Finally, the origin of the subordinators are explained by comparing them with those found in Selknam, a language that, like Tehuelche, belongs to the Chon family.

This study investigates the isotopic signatures of human skeletal remains that were recovered from several sites along the coast and inland in the north-central Patagonian region of Argentina. Human skeletal remains, dating from 2500 BP through the early historic period, are examined to determine the relative significance of terrestrial and aquatic food resources and subsequently, the extent to which coastal food resources were exploited by indigenous Argentinians. Carbon and nitrogen isotopes contained within human bone collagen and apatite are measured quantitatively to determine the relative significance of marine and terrestrial foods. This study, one of the first isotopic studies of indigenous diet on the Atlantic coast of Argentina, is significant because it provides initial results to be used for the reconstruction of aboriginal subsistence patterns prior to and after European contact.
