Plant DNA metabarcoding record from a sediment core from Lake Naleng, southeastern Tibetan Plateau

Here, we provide the raw plant DNA metabarcoding data archived in Lake Naleng sediment core spanning the late-glacial to the present (17,700 to 0 cal yr BP).

Lake Naleng (31.10° N, 99.7°5 E, 4200 above sea level) is situated in a glacially-formed basin on the southeastern Tibetan Plateau. It is an alpine freshwater lake with a maximum water depth of 36.7 m, an open surface area of 1.7 km2,  a specific conductivity of 0.045 mS/cm, a Secchi depth of 2.9 m, a pH of 8.1, a dissolved oxygen content of 6.9 mg/L (measured 19.09.2003), and a catchment area of 128 km2. The catchment is used for seasonal grazing by yaks and sheep. The lake is located at the upper treeline with main vegetation of alpine meadow. The detailed geographic, biogeochemical and vegetation information are described in Kramer et al., 2010a, b, c (doi: 10.1007/s00334-009-0219-5, 10.1016/j.yqres.2009.12.003, and 10.1016/j.palaeo.2009.12.001) and Opitz et al., 2015 (doi: http://dx.doi.org/10.1016/j.quascirev.2015.03.011).

本数据集提供了保存在纳伦湖（Lake Naleng）沉积物岩芯中的植物DNA宏条形码（DNA metabarcoding）原始数据，时间跨度为晚冰期至今（距今17700至0校准年）。
纳伦湖（31.10°N，99.75°E，海拔4200米）坐落于青藏高原东南部的冰川成因盆地中，为高山淡水湖。该湖最大水深36.7米，开阔水面面积1.7平方千米，比电导率0.045毫西门子/厘米，塞氏深度2.9米，pH值8.1，溶解氧含量6.9毫克/升（2003年9月19日测定），流域面积128平方千米。流域内以牦牛和绵羊开展季节性放牧，该湖处于林线之上，原生植被以高山草甸为主。其详细的地理、生物地球化学及植被相关信息可参考Kramer等（2010a、2010b、2010c）以及Opitz等（2015）的研究文献，对应DOI分别为10.1007/s00334-009-0219-5、10.1016/j.yqres.2009.12.003、10.1016/j.palaeo.2009.12.001及http://dx.doi.org/10.1016/j.quascirev.2015.03.011。……
