Wardle Marie-Charlotte Nilsson Hegethorn Paul Kardol October 2020 This file explains the variables in the file "BryoC_mossMC_201020.csv", which includes data related to moss moisture content in the mesocosms. The data is described in the paper "Precipitation regime controls bryosphere carbon cycling similarly across contrasting ecosystems", published in the journal Oikos. Please refer to the paper for further details. meso_id: ID of the mesocosm. days_since_water: days since water was added to the mesocosm. percent_wet: percentage of the moss cover that appeared wet, estimated visually. mossMC: estimated moss moisture content, expressed as the percentage of the dry weight, based on empirical relationships between moss moisture content measured gravimetrically and the visually estimated cover of wet moss.
