Alaskan Peatland Experiment: Community structure and productivity data for 2007-2010 V - Moss NPP

This dataset contains net primary productivity (NPP, g/m2/yr) for sphagnum, feather moss, brown moss and dicranum moss types estimated for 2009 and 2010 at both bog and fen sites of the Alaskan peatland experiment. Within the fen site a water table manipulation has been ongiong since 2005, with control, lowered and raised water table treatment plots. Samples at the bog were collected in a plot established within the lowland black spruce permafrost plateau (permafrost), and two plots established within collapse scars embedded within the plateau. One collapse scar formed ~ 45 years ago (old collapse) and the other formed ~ 25 years ago based upon aerial photography provided by the BCEF LTER. The data provided in this data set can be sorted by site and plot.

本数据集涵盖阿拉斯加泥炭地实验（Alaskan peatland experiment）中2009年与2010年的观测数据，包含泥炭藓（sphagnum）、羽藓（feather moss）、棕藓（brown moss）及曲尾藓（dicranum moss）四类苔藓的净初级生产力（net primary productivity，NPP，g/m²/yr），采样覆盖该实验的沼泽（bog）与碱沼（fen）两类样地。碱沼样地自2005年起持续开展水位调控实验，设置了对照组、降水位与升水位三种处理样地。沼泽样地的采样样地设于低地黑云杉永久冻土高原（lowland black spruce permafrost plateau）内，另有两处样地设于嵌入该高原的塌陷坑（collapse scars）中；根据BCEF LTER提供的航空影像资料，其中一处塌陷坑形成于约45年前（旧塌陷坑），另一处形成于约25年前（新塌陷坑）。本数据集收录的数据可按样地与样方进行分类筛选。
