Are you passionate about trees and climate change? Are you interested in solving important and relevant questions regarding forest responses to global change? Do you want to perform cutting edge isotope and tree ring work? Then please apply for this fully funded PhD to work in a dynamic, cross-disciplinary team on the Leverhulme funded research project “Unlocking the full potential of tree ring oxygen isotope archives”.
<p style="margin-bottom:11px">Both increases in atmospheric CO2 and the resulting climatic changes (e.g. warming) are affecting forests globally (). Atmospheric CO2 increases reduce CO2 limitation of trees’ photosynthesis, possibly leading trees to downregulate stomatal conductance and thereby transpiration rates. The warming of the Earth surface affects tree functioning directly and indirectly through changes the Earth’s hydrological cycle (i.e. increasing intensity and frequency of droughts and floods). Our understanding how forests respond to these complex drivers remains incomplete, but is important as we depend on forests for maintaining biodiversity, clean water and air, and as forests are large carbon stores.</p> <p>An important approach towards gaining insight in tree responses to global change is the use of tree rings and isotopes. Carbon isotope variation in tree rings provide indications of changes in plant water use efficiency, while oxygen isotopes provide a mixed signal of the plant source water and plant physiological changes to their environment. In theory, the combined use of the two isotopes in tree rings therefore potentially allows disentangling climate from tree physiology responses, but current methods are limited as oxygen isotopes provide a mix of signals from the plant water source and plant physiology (primarily leaf level processes). To make full use of these approaches we require new developments to enable to separate these signals. <strong>In this project you will help developing and testing novel multi-proxy tree ring isotope approaches to assess the responses of trees to CO2 and climate.</strong> This will be done through working in a multidisciplinary team consisting of biochemists, Earth scientists, ecophysiologists, and isotope specialists.</p> <p>You will apply new chemical techniques to tree ring samples to separate oxygen isotope signals originating from the source water from those related to tree physiology and test these approaches on a range of sites and species. For this test you will make use of existing samples and complement these with new field collections from a number of sites, including possibly tropical trees. For a select set of species you will then develop long tree ring isotope chronologies to assess the long-term response to climate and CO2. This research is expected to provide new insights in plant ecophysiological responses, and improve the interpretation of oxygen isotopes from tree rings for palaeoclimate studies.</p> <p style="margin-bottom:11px"> </p> <h4 style="margin-bottom: 11px;">Information about the Award</h4> <p>We are offering 1 full-time PHD scholarship in the School of Geography for one UK candidate, covering a matching UKRI maintenance stipend (currently £17,668 in 2022/23) and UK tuition fees for three and a half years, subject to satisfactory progress. </p> <p> </p> <h4>Duration of the Award</h4> <p>Full-time (3.5 years).
