[{"name":"stordalen-malhotra-2024-litter-1","title":"Litter bag decomposition at Stordalen mire 2011\u200a\u2013\u200a2013","summary":"The dataset contains litter decomposition rates using 3 litter bags collections and their covariate environmental data. We measured in-situ decomposition of representative plant litter and environments over two years across a permafrost thaw gradient at Stordalen Mire, Sweden.\r\n\r\nLitter decomposition, a key process by which recently fixed carbon is lost from ecosystems, is a function of environmental conditions and plant community characteristics. In ice-rich peatlands, permafrost thaw introduces high variability in both abiotic and biotic factors, both of which may affect litter decomposition rates in different ways. \r\n\r\nLitter bags were installed at a 5 cm depth in 2011 and three collections were made in spring 2012 (capturing winter and spring leaching), fall 2012 (capturing summer rate) and fall 2013 (capturing annual rate). Litter bags contained representative plant litter of the habitat type. The litter was collected from Stordalen in 2011. Covariate environmental data are also reported and include information about moisture, water table, pH, and pore-water carbon and nitrogen content. ","citations":"Malhotra, A., Moore, T.
