“…In the northwestern Amazon rainforest/savanna transition zone (Llanos Orientales in Colombia) rainforest expansion is documented since 6850 cal BP and was further intensified after 3200 cal BP (Behling & Hooghiemstra 2000). In southwestern Amazonia, there is evidence of Amazon rain forest expansion (Laguna Bella Vista and Chaplin, Bolivia) during the late Holocene at least since 3200 cal BP (Mayle 2011;Mayle et al 2000). The expansion of the Amazon rain forest after 6260 cal BP is also reported for the southeastern Amazon region (Behling 2002).…”

“…Se conocen diversos antecedentes de trabajos interdisciplinarios utilizando multiproxies para el Holoceno en los Andes Centrales, particularmente en el Noroeste Argentino (Lupo, 1998;Kulemeyer & Lupo, 1998;Kulemeyer et al, 1999;Schäbitz et al, 2001;Kulemeyer, 2005;Torres, 2010;Cortes, 2010;Bonachea et al, 2010;Yacobaccio et al, 2013). Metodológicamente, se puede destacar el trabajo de Lupo et al (2006), en un sector boscoso de Yungas, mientras que los antecedentes de estudios con alta resolución para el último siglo en zonas boscosas del Amazonia de Brasil y Bolivia son escasos (Villagrán, 1993;Argollo & Mourguiart, 2000;Burbridge et al, 2004;May, 2007;May et al, 2008;Bonachea et al, 2010;Behling, 2011;Mayle, 2011;May, 2011).…”

First results from an interdisciplinary research on the history of landscape in the mountain range of Tartagal, Province of Salta (NW Argentina) for the 1959/2012 period are given. Geochemical, mineralogical and palynological studies with high temporal resolution have been performed in sediments of a core from Laguna Seca (22°21'1.81"S, 63°52'10.90"W). Dentations by 210 Pb show that the sedimentary record comprises 53 years. Sediments are composed of reddish massive clays and silts, with interbedded clays rich in organic matter and fibrous plants macro remains in the base of the core. Presence of quartz, illite and clinochlorite is prominent; most relevant geochemical components are Al, Si and K. Redundancy analysis indicates that most of chemical elements are associated to terrigenous minerals (quartz, albite and illite). Pollen types found belong to the Yungas forest, like Alnus acuminata, Anadenanthera colubrina, Celtis sp. and Schinus sp. Geochemical, mineralogical and palynological results are consistent with the annual precipitation in Tartagal during last decades, and reflect some correlation with phenomena of mass movement as well as landslides occurred in the mountain range of Tartagal and its oriental piedmont. The multiproxies data integration has generated the basis for reconstructing changes in vegetation, climate and history of anthropogenic disturbance during the Holocene in Subandine Sierra the Northwest Argentine.
