“…Similarly, Chenopodioideae pollen content is inversely correlated to pollen indicators of local humidity and the diatom HI, and positively correlated to the abundance of aerophile diatoms. While some have argued that Chenopodioideae pollen abundance is a more robust indicator of human disturbance than of environmental change (Lupo et al ), the correlations of this variable with others in our analysis underscore the value of Chenopodioideae pollen abundance as an indicator of aridity in our regional sedimentary sequences (Table ).…”

Environmental trends between 2400 and 1200 BP in Barrancas, Argentinean Puna: Impacts on local resource variability and socioeconomic organization

This paper presents a multiproxy analysis—geomorphology, organic matter, and carbonate content, diatoms, pollen, and magnetic properties of sediments—of the Barrancas Pueblo profile, located in Barrancas, Jujuy, Argentina (S 23°18′08,7; W 66°05′15,2; 3666 m.a.s.l.) to explore local environmental change over the last few millennia. This study is part of a broader investigation of the environmental conditions that facilitated and/or triggered the development of a mixed herding and hunting economic strategy during the late Holocene. The results suggest ongoing local moisture availability for most of the late Holocene; between 2400 and 1500 BP there was a stable, low energy environment that supported a vegetated floodplain, resulting in high availability of pasture and water. However, throughout most of the studied period, there were punctual arid episodes and erosion of the river catchment. High environmental variability post‐3000 cal BP could have put a premium on strategies to reduce the risk associated with resource unpredictability, such as economic specialization and intensification and storage practices designed to control and mitigate resource variability. This process could have ultimately lead to the consolidation of the Andean pastoralist way of life ca. 3000–2500 BP.

“…En este sentido, podemos observar una disminución de birrefringencia y contornos rugosos, como así también modificaciones en la cruz de extinción que podrían deberse a eventos de hervido o tostado (Babot, 2003). Por último, entre los elementos no fitolíticos encontrados, se documentó la presencia de espículas de esporangio (muestras F y E), fibras vegetales en todos los fragmentos analizados y granos de polen en las muestras A, B, D, E y F, de los cuales tres (N=3) fueron vinculados al complejo Amaranthaceae/Chenopodiaceae (muestras A, D y F) (Lupo et al 2018) (Tabla 1).…”

En este trabajo se presentan los primeros resultados arqueobotánicos obtenidos a partir del análisis de microrrestos vegetales (fitolitos y granos de almidón) adheridos en fragmentos cerámicos del sitio arqueológico Isla Orihuela Costa Sudeste (487±45 14C años AP) ubicado en la isla homónima, laguna Mar Chiquita, provincia de Córdoba. Este tipo de análisis, inédito para la zona, aporta evidencia sobre el procesamiento y selección de diversas plantas por parte de los grupos humanos que habitaron la costa sur de la Laguna Mar Chiquita durante el Holoceno tardío. Los resultados obtenidos indican la presencia de asociaciones fitolíticas compuestas principalmente por las subfamilias Panicoideas, Chloridoideas y Danthoniodeas, como así también elementos almidonosos de diversa morfología. Los elementos encontrados sugieren la presencia de plantas silvestres como el algarrobo (Prosopis sp.) y el chañar (Geoffroea decorticans) y de cultivadas como el maíz (Zea mays) en los tiestos analizados.

“…Ongoing research is focused on elucidating changes in vegetation and land use history during the Holocene in the Puna region using a pollen analysis approach (Albeck et al, 2017; Lupo et al, 2017). However, in northwestern (NW) Argentina, the relationship between fossil pollen records and modern vegetation of steppes and grasslands in semiarid environments of the Central Andes is often poorly understood due to the lack of studies (Torres et al, 2019).…”

“…Specifically, in the Argentine Puna, several researchers have focused on the study of changes in vegetation using pollen as the main line of evidence related to the history of land use since the earliest hunter-gatherer occupations recorded from the Early Holocene (10,000 years BP) up to the Late-Holocene, when a predominantly pastoral economy began to develop (ca. 2500 years BP) (Albeck et al, 2017;Lupo et al, 2017;Yacobaccio et al, 1997Yacobaccio et al, -1998.…”

The present research is framed within an interdisciplinary archeological project that aims to reconstruct the environmental conditions in which human occupations developed in the locality of Barrancas, Dry Puna Argentina, during the Holocene. The aims of this work were to: (1) study the regional vegetation and the modern pollen dispersal-sedimentation process; and (2) generate a reference database for interpretation of the fossil pollen records of the Holocene in the Dry Puna (3) provide information for the study of the relationship between human populations and vegetation in the area during the Late-Holocene. The results show that the main pollen types that characterize the regional vegetation were represented in the surface samples (herbaceous steppe, shrub steppe, mixed steppe, and vegas). Also the environments with evidence of anthropic impact were identified by specific plant species and the corresponding pollen grain. The representation of the vegetation was quantified according to the different pollen types. The study used indices of association to establish relationships between modern pollen and vegetation, and showed a weak association for Solanaceae and Verbenaceae; an over-representation of Ephedrae, Alnus acuminata, Malvaceae, Chenopodiaceae-Amaranthaceae; an association of Asteraceae; the absence of association of Cactaceae and Portulacaceae; and a strong association of Poaceae. These results allow us to specify the interpretation of fossil records and past environments in relation to anthropic modifications on the landscape.
