Identifying the secular evolution of chemical heterogeneity in the mantle as probed by deep mantle plumes. This project aims to focus on modes and timescales of melting associated with deep mantle plumes. These melts form massive magmatic bodies and volcanic flood basalt provinces throughout Earth’s history and record the secular chemical evolution of the Earth’s mantle. Selective igneous bodies contain high-grade noble metal deposits and coincide with global mass extinction linked to anoxic oce ....Identifying the secular evolution of chemical heterogeneity in the mantle as probed by deep mantle plumes. This project aims to focus on modes and timescales of melting associated with deep mantle plumes. These melts form massive magmatic bodies and volcanic flood basalt provinces throughout Earth’s history and record the secular chemical evolution of the Earth’s mantle. Selective igneous bodies contain high-grade noble metal deposits and coincide with global mass extinction linked to anoxic ocean events in response to atmospheric volcanic pollution. This project aims to provide knowledge of planetary surface evolution in response to mantle dynamics, place constraints on enrichment processes of metals in ore quality in plume-derived melts, and may help understandings of the relation between massive volcanic eruptions and climate variability.Read moreRead less
REdefining metabolic Schemes and Pathways In plant leaf REspiration. Leaf respiration-related metabolism in terrestrial vegetation liberates considerable amounts of carbon dioxide, ammonia and hydrogen sulphide into the atmosphere. Such gaseous losses are detrimental to biomass production but respiration also sustains nutrient assimilation and biosyntheses. This project aims to describe flux patterns in respiratory metabolism and disentangle interactions with other pathways such as photorespirat ....REdefining metabolic Schemes and Pathways In plant leaf REspiration. Leaf respiration-related metabolism in terrestrial vegetation liberates considerable amounts of carbon dioxide, ammonia and hydrogen sulphide into the atmosphere. Such gaseous losses are detrimental to biomass production but respiration also sustains nutrient assimilation and biosyntheses. This project aims to describe flux patterns in respiratory metabolism and disentangle interactions with other pathways such as photorespiration and nitrogen assimilation. It will exploit stable isotopes to quantify metabolic partitioning and show coordination between major processes. It will establish key mechanisms by which respiration dictates plant carbon balance and contributes to identifying metabolic bottle-necks in plant primary production.Read moreRead less
