Transpiration, Tracheids and Tree rings: Linking stem water flow and wood formation in high-elevation conifers, Thesis at the University of Basel, Basel.
Photosynthesis represents the process where the water cycle meets the carbon cycle. For each kilogram of carbon allocated, a plant transpires between 100 and 1000 kilograms of water. Yet, these quantifications are strongly influenced by the environmental setting and species which play key roles in determining interactions between the water and carbon balance from single plants to the land-atmosphere fluxes across the Earth. LOTFOR aims at elucidating the coupling between the carbon and hydrological cycle in the context of increasing temperature by quantifying water flow and growth processes occurring in the stem of conifer trees. We will cajavascript:__doPostBack('ctl00$ctl00$CPH_Content$CPH_Content$ctl04$LSV2$DCTN$LB_Submit','')pitalize upon a unique research setting located along a temperature (altitudinal) gradient and additionally perform investigations at contrasting wet and dry sites. Data collected in this project on plant-water relations (sap flow and stem diameter variation, soil, xylem and leaf water oxygen isotopes) will complement multi-annual high resolution measurements of tree growth (e.g., weekly xylogenesis observation, hourly stem size variation, tree-ring width and cell anatomy and density profiles) as indicators for structural carbon allocation to provide a comprehensive framework to link variability in the carbon and hydrological cycles. By quantifying transpiration and its variation in relation to the major climatic drivers (Module A) and stem biomass accumulation over time (Module B) we will be able to improve our process-based understanding of how daily to annual structural carbon allocation (amount and shape of tracheids) in the forming ring is linked with the water flowing through the stem (Module C). Based on such relationships we will improve an existing tree model (De Schepper & Steppe, 2010) linking water and sugar transport in living trees. The refined model will serve as a basis to link past climatic, tree-ring width and isotope data, and will be used for predictions of forest responses under a warming climate. The detailed quantification of the water-carbon relationships are the basis for a better process-based understanding of how these factors interact in shaping annual tree-ring structures and production in conifers.
