OverviewAI-generated summary
Reti Ranniku's research focuses on the biogeochemistry of greenhouse gas emissions from terrestrial ecosystems. Their work investigates the dynamics of methane (CH₄), nitrous oxide (N₂O), and carbon dioxide (CO₂) fluxes from various environmental compartments, including soil, tree stems, and forest ecosystems. Recent studies have examined these emissions in drained peatland forests, riparian forests, and tropical cloud forests, considering factors such as freeze-thaw cycles, dry and wet periods, and the influence of microbial communities.
Ranniku has explored greenhouse gas emissions from ditches in oil palm plantations and analyzed the abundance of nitrogen cycling genes in different forest ecosystems. Their research also encompasses the role of tree stems as sources of CH₄ and N₂O, particularly during winter periods in hemiboreal drained peatland forests. Metrics indicate a research profile with 33 publications and 110 citations, an h-index of 5.
