Molecular understanding of phosphorus dynamics in terrestrial and aquatic ecosystems
The interplay between biosphere and the environment is at the core of global climate change. Organic P compounds are key determinants of primary production in many terrestrial and most aquatic ecosystems. The ability for plants or microorganisms to utilize organic P is an important part of the P dynamics and has implications for ecosystem functioning. Knowledge on the speciation and reactivity of the organic P pool is thus a key issue in both terrestrial and aquatic science.
This project will create unique, molecular-scale knowledge about the transfer mechanisms between various biogeochemical pools of phosphorus in both terrestrial and aquatic ecosystems. The research will benefit a broad range of fundamental ecological and geochemical questions and will be an important contribution to the application of NMR to natural samples and brings together a multidisciplinary group of researchers.
· Develop methods for speciation of organic P in soils and freshwater ecosystems by means of different 31P NMR techniques.
· Apply the 31P NMR techniques on environmental samples to unravel the molecular details of how different organic P species in terrestrial and aquatic ecosystems relate to vegetation, climate and microbial bioavailability.
Applicants must have a Ph.D. in chemistry or a related field.
