Use of pollen data in archaeological sites of Patagonia: statistical methodologies, reaches and interpretative limits

The archaeological sites of Santa Cruz have provided important information about vegetation and climate changes at different spatial and temporal scales. In this paper we present methodological examples to analyze modern pollen and fossil record data of four archaeological sequences (CMN1 and COCU,...

description The archaeological sites of Santa Cruz have provided important information about vegetation and climate changes at different spatial and temporal scales. In this paper we present methodological examples to analyze modern pollen and fossil record data of four archaeological sequences (CMN1 and COCU, at 47 ° S, 71 ° W and B1Oq and CPD at 49 ° S, 72 ° W) west of Santa Cruz. Based on these results, we discussed the scopes and interpretative limits of the data used. Our results indicate that the vegetation units were differed with statistical significance at local and regional scales for both areas. The studied sequences have allowed us to estimate the spatial representation of the fossil record through a Detrended Correspondence Analysis. CMN1 and CPD reflect vegetation changes at mesoscale verifiable with other natural sequences (47 ° - 49 ° S and 50 ° S), while COCU and B1Oq indicate a local vegetation signal. While should consider carefully the data scope to address the palaeoenvironmental question, that archaeological sequences provide valuable information and are very important in those environments where continuous natural sequences are not available. In this article, we conclude that statistical analysis are an important tool that complements our analyzes. Also, it is necessary to know the study areas particularities, the surrounding vegetation, its geomorphology and the spatial representation of modern and fossil records to reflect with high fidelity the pollen studies.

Los sitios arqueológicos presentes en Santa Cruz han brindado importante información sobre los cambios de la vegetación y del clima en diferentes escalas espaciales y temporales. En este trabajo presentamos ejemplos metodológicos para analizar los datos polínicos actuales y del registro fósil de cuatro secuencias arqueológicas (CMN1 y COCU a los 47°S; 71°O y B1Oq y CPD a los 49°S; 72°O) ubicadas al oeste de Santa Cruz. A partir de estos resultados se discuten los alcances y los límites interpretativos de los datos utilizados. Nuestros resultados indican que los análisis polínicos actuales han permitido diferenciar con significancia estadística las unidades de vegetación a escala local y regional para ambas áreas. Las secuencias estudiadas han permitido estimar la representación espacial de los registros fósiles mediante un análisis de correspondencia destendenciado. CMN1 y CPD reflejan cambios en la vegetación a mesoescala y a escala regional verificables con otras secuencias continuas de lagos y mallines (47°-49º; 50°S), mientras que COCU y B1Oq indican una señal local de la vegetación. Si bien debe considerarse cuidadosamente el alcance de los datos para abordar la pregunta paleoambiental, las secuencias arqueológicas brindan valiosa información y son muy importantes en aquellos ambientes donde no hay disponibilidad de secuencias naturales continuas (como lagos, mallines, lagunas). En este trabajo concluimos que los análisis estadísticos son una herramienta importante que complementan nuestros análisis. Además, es necesario conocer las particularidades de las áreas de estudio, la vegetación circundante, su geomorfología, y la representación espacial de los registros actuales y fósiles para reflejar con mayor fidelidad los estudios polínicos.
