oscillating peat surface levels in a restiad peatland

Floral and environmental gradients on a Late Cretaceous

Introduction As phylogenetic data, techniques, and understanding have improved rapidly in recent years, it has become increasingly common to reconstruct the ecological history of groups using phylogenetic trees derived from analyses of living species (e.g., Feild Get price

The accumulation of peat is negatively impacted by reduced growth of Sphagnum species in peatlands (Dieleman, Branfireun, Mclaughlin, Lindo, 2015), and hydrology processes are affected by the loss of soil crusts in dryland communities (Ferrenberg, Reed). Get price

Methylotrophs, which can utilize methane and/or methanol as sole carbon and energy sources, are key players in the carbon cycle between methane and CO2, the two most important greenhouse gases. This review describes the relationships between methylotrophs and plants, and between methanotrophs (methane-utilizers, a subset of methylotrophs) and heterotrophic bacteria. Some plants emit methane Get price

Coniferous forest data indicates that SOC increased from 31.3% in the surface layer to 34.9% for the middle layer before decreasing to 15.1% at depth. A likely explanation for this trend is that afforesting peat soil is leading to increased decomposition in the surface soil layers and a steady state of carbon loss and gain from the soil profile has not been reached.
