OverviewAI-generated summary
Reti Ranniku investigates greenhouse gas fluxes from various ecosystems, with a focus on forest soils and trees. Their research examines the dynamics of methane (CH4), carbon dioxide (CO2), and nitrous oxide (N2O) emissions, particularly in drained peatland forests. Ranniku's work has explored how environmental factors such as dry and wet periods, freeze-thaw cycles, and meltwater influence these emissions and the associated microbial communities. Recent publications also extend to greenhouse gas emissions from ditches in oil palm plantations on tropical peatlands and nitrogen cycling genes in tropical cloud forests. Ranniku has authored or co-authored 30 publications with 93 citations and holds an h-index of 5.
