OverviewAI-generated summary
Reti Ranniku's research investigates greenhouse gas fluxes from terrestrial ecosystems, with a particular focus on forest soils and tree stems. Their work examines the dynamics of methane (CH4), carbon dioxide (CO2), and nitrous oxide (N2O) emissions under various environmental conditions, including long-term changes, freeze-thaw cycles, and dry and wet periods. Ranniku's studies have explored these fluxes in different forest types, such as riparian forests and drained peatland forests, and have also extended to the sub-Antarctic and tropical peatlands. A key aspect of this research involves understanding the role of soil microbiology in governing these greenhouse gas cycles. Ranniku has also investigated emissions from ditches in oil palm plantations and the contribution of tree stems as a source of CH4 and N2O, particularly during winter periods. Their work contributes to the broader understanding of ecosystem responses to environmental changes and their impact on global greenhouse gas budgets.
