| description |
In this work we present the first systematic results about regional isotopic ecology in northern Neuquén Province (Argentina). This information is essential to reconstruct ecological changes and human paleodiets through time. We conducted analyses of stable isotopes of carbon (13C/12C) and nitrogen (15N/14N) on the collagen fraction of bone from one human sample and 39 faunal samples from archaeological sites in Barrancas-Buta Ranquil locality. The results correspond to five wild species, though analysis is focused in guanaco (Lama guanicoe). The information produced is interpreted in the framework of regional botanical surveys that show the differential abundance of species with different photosynthetic pathways. Due to its position, next to the ecotone between the Monte and Patagonia phytogeographical provinces, the area is a sensitive spot to test ecological changes through time. The species recorded in the botanical transects follow the C3 photosynthetic pathway. Accordingly, the values produced for faunal samples reveal C3-based trophic chains. The human burial from Buta Có Abajo shows values indicative of a diet based on camelids, which would have also included small animals with higher isotope values. The samples analyzed for guanaco show differences between the early and late Holocene components from CH1, where the more recent assemblage shows a more intense consumption of C3 plants. By integrating data available for neighbor southern Mendoza region, we evaluate regional isotopic patterns associated to altitude and latitude. We do not recorded strong relations between altitude and ?13C and ?15N values. On the other hand, there is a weak latitudinal pattern in ?13C values, which show more depleted values in CH1 compared to settings located further north. |

En este trabajo se presentan los primeros resultados de ecología isotópica regional para el extremo norte de la provincia del Neuquén (Argentina). Esta información es clave para la reconstrucción de cambios ecológicos y paleodietas humanas a través del tiempo. Se exponen los resultados obtenidos a partir de la medición de isótopos estables de carbono (13C/12C) y nitrógeno (15N/14N) sobre el colágeno óseo de 39 muestras de fauna y una muestra humana procedentes de sitios arqueológicos de la localidad Barrancas-Buta Ranquil. Se presentan datos para cinco especies silvestres, aunque el foco del análisis se centra en guanaco (Lama guanicoe). La información es interpretada en el marco de los resultados obtenidos de muestreos de vegetación en la región, los cuales indican la distribución y abundancia de especies con las distintas vías fotosintéticas. Debido a su posición, adyacente al ecotono entre las comunidades fitogeográficas del Monte y la Patagonia, la región ofrece un contexto adecuado para el análisis de cambios ecológicos a través del tiempo. La totalidad de las especies vegetales relevadas en el muestreo sistemático siguen la vía fotosintética C3. En concordancia con esto, los valores de especies animales fueron relacionados a una cadena trófica C3. El entierro humano del sitio Buta Có Abajo registró valores que sugieren una dieta compuesta por guanacos y que además incluyó animales pequeños con valores más enriquecidos. En cuanto a los guanacos, se registraron diferencias isotópicas entre las muestras asignadas al Holoceno temprano y el tardío; estas últimas reflejan un mayor consumo de especies con vía fotosintética C3. Por último, en este conjunto de muestras, no se registró relación entre la altitud y los valores isotópicos de ?13C y ?15N, mientras que se observaría una tendencia latitudinal en la que los camélidos del centro sur de Mendoza presentan un mayor consumo de especies vegetales C4 que las procedentes del norte de Neuquén.
