      abstract     = {High-altitude cushion peatlands are versatile archives for
                      high-resolution palaeoenvironmental studies, due to their
                      high accumulation rates, range of proxies, and sensitivity
                      to climatic and/or human-induced changes. Especially within
                      the Central Andes, the knowledge about climate conditions
                      during the Holocene is limited. In this study, we present
                      the environmental and climatic history for the last 2100
                      years of Cerro Tuzgle peatland (CTP), located in the dry
                      Puna of NW Argentina, based on a multi-proxy approach. X-ray
                      fluorescence (XRF), stable isotope and element content
                      analyses (δ13C, δ15N, TN and TOC) were conducted to
                      analyse the inorganic geochemistry throughout the sequence,
                      revealing changes in the peatlands' past redox conditions.
                      Pollen assemblages give an insight into substantial
                      environmental changes on a regional scale. The palaeoclimate
                      varied significantly during the last 2100 years. The results
                      reflect prominent late Holocene climate anomalies and
                      provide evidence that in situ moisture changes were coupled
                      to the migration of the Intertropical Convergence Zone
                      (ITCZ). A period of sustained dry conditions prevailed from
                      around 150 BC to around AD 150. A more humid phase
                      dominated between AD 200 and AD 550. Afterwards, the
                      climate was characterised by changes between drier and
                      wetter conditions, with droughts at around AD 650–800
                      and AD  1000–1100. Volcanic forcing at the beginning of
                      the 19th century (1815 Tambora eruption) seems to have had
                      an impact on climatic settings in the Central Andes. In the
                      past, the peatland recovered from climatic perturbations.
                      Today, CTP is heavily degraded by human interventions, and
                      the peat deposit is becoming increasingly susceptible to
                      erosion and incision.},
