      abstract     = {A Late Holocene paleoenvironmental record was obtained from
                      the Lagunillas cushion peatland (LP, 27°12'S, 69°17'W),
                      located in the dry Puna of the western Central Andes. Ten
                      radiocarbon dates build the chronology for the last 1800 cal
                      a BP. Analyses of stable isotopes on cellulose (d18Ocell,
                      d13Ccell) and geochemicalproxies on organic matter (d13COM,
                      d15Nbulk, TOC, TN, LOI, T535) were conducted to identify
                      major paleoenvironmental changes in this record.
                      Simultaneously, ambient water (d18O, d2H) and plant samples
                      of the dominant species Oxychloe andina (d18Ocell, d13Ccell)
                      reveal insights into modern conditions. The record
                      revealsdistinct multi-centennial oscillations of peat layer
                      thickness and d18Ocell. Decomposition, changes in the
                      dominating plant species as well as in plant parts
                      (leaves/roots) can be excluded as driving factors for these
                      oscillations. Thus, d18Ocell seems to be externally forced
                      and reflects humidity changes. Around 470 cal a BP a
                      distinct change towards increased humidity occurred, lasting
                      during the Little Ice Age until about 70 cal a BP. Humid
                      conditions prevailed between 1530 and 1270 cal a BP.
                      Increasing d18Ocell values since 30 cal a BP mark a trend
                      towards again increased aridity.},
