Lisa Wingate • Senior Scientist  (ERC SOLCA team leader)  

Tel: +33(0)55712-2431  Email: lisa.wingate@bordeaux.inra.fr

Lisa received her PhD from The University of Edinburgh (under the supervision of Professors Paul Jarvis FRS and John Moncrieff). She remained at Edinburgh to pursue postdoctoral research with Professor Maurizio Mencuccini on the European project MIND. This project involved developing automated chamber systems to measure continuously variations in soil CO2 efflux during drought and irrigation treatments in a Mediterranean montado ecosystem in Portugal. Lisa then teamed up with Professor John Grace on another European project called CarboEurope under the Innovation workpackage. During this postdoc Lisa worked with teams in France to measure at high-resolution the variations of 13CO2 and CO18O for different components within a Maritime pine ecosystem in France. This experience was the catalyst for a longer term involvement with the team at INRA Bordeaux where she continued to work with Jérôme Ogée on the tree-ring project MIST, funded by the national funding agency, ANR. Shortly after this Lisa secured a Marie Curie fellowship to continue research in France. Only after a few months working on the Marie Curie Lisa was offered a chance to build her own group at The University of Cambridge through the award of a Advanced NERC fellowship for 5 yrs.


Screen Shot 2016-02-27 at 10.48.33 PMFinally in 2012, Lisa obtained a permanent position to build her research program with INRA back in Bordeaux. Her research focuses on the biological response of terrestrial ecosystems to environmental change, and how different ecosystem processes impact the exchange of water, CO2 and energy between the Earth’s surface and the atmosphere. Recent recognition of her research efforts have resulted in the award of the ERC starting grant SOLCA in 2013 and the INRA Laurier prix for the young researcher of 2014. Since then Lisa has been building a dynamic and talented team in Bordeaux to solve some global scale puzzles.



Research Activities ♦ My research focuses on understanding the ecophysiological response of soils and plants to short term and long term variations in environmental drivers. I am particularly curious to understand how ecosystem components will respond to changes in future climate and how the functional response of ecosystems could in turn modify climate.

Tools ♦ For this I use a suite of different tools to study plant functional responses both in the laboratory and in the field. These tools range from cheap and cheerful digital cameras to monitor changes in canopy structure and colour, to sophisticated fast response mid infra-red laser absorption spectrometers to observe photosynthesis, respiration and transpiration.

Expertise ♦ One of my main expertise is using the stable isotope signals (18O/16O, D/H, 13C/12C) of plant and soil material (organic matter, metabolites, cellulose, waxes), atmospheric CO2 and ecosystem water pools (leaves, xylem, soil) as recorders of ecosystem function (photosynthesis, stomatal control,water transport, carbon allocation) and as additional constraints on the biogeochemical cycles of carbon and water over land surfaces and their climatic feedbacks.

Current Research Themes and Projects


Developing new tracers of the C cycle (COS, CO18O) ♦ I am currently developing multi-tracer experimental approaches and model algorithms to constrain current estimates of photosynthetic and respiratory fluxes over large-scales to improve our understanding of inter-annual swings in the CO2 sequestration capacity of the terrestrial biosphere.

Screen Shot 2016-04-09 at 10.55.38 PMThis research is conducted as part of three projects I currently co-ordinate: the ERC project SOLCA (2014-2018), the Bordeaux Idex project USIFLUX (2014-2016) and the Marie Sklowdoski Curie fellowship USIFLUX (2016-2018).

Understanding the variability and function of Carbonic Anhydrase activity across ecosystems  ♦ For a number of years  I have been developing methods to measure the impact of the enzyme Carbonic Anhydrase on the exchange of CO18O with soil water pools. I have collected data on the activity of this enzyme in soils from a range of ecosystems and I am now trying to understand why it varies from one location to the next and how we might transfer this knowledge into process-based carbon cycle models at different scales. In order to do this I have been working with a team of highly motivated researchers from all over the world, conducting measurements in a new gas exchange lab with climate control facilities. We are currently building carbonic anhydrase and sequenced DNA datasets of micro-organisms that either live in or on the soil surfaces of different biomes. In particular, we have recently been measuring the CA activity of soil algae, lichens, liverworts and mosses and discovering how these organisms can help us understand variations of COS and CO18O in the atmosphere.

Response and adaptation of plant phenology to global change

♦  Over the last few years I have been involved in the creation and co-ordination of a European network of digital cameras. These cameras have been strategically mounted in ecosystems that are being measured intensely by a platform of instruments carefully selected to monitor both fast (hours to days) and long-term (>10 yrs) changes in weather patterns. These sites also measure continuously how these ecosystems respond to fluctuations in weather by using eddy covariance techniques that provide a measure of the exchanges of water, CO2 and energy between the ecosystem and the atmosphere. Thus with cameras we can effectively keep a continuous ‘eye’ on the ecosystem and link changes in canopy health, duration and colour to the functional status of the canopy. Ultimately with long digital images archives we will be able to explore how climate variability affects the length of the leafed period and the carbon and water budgets of various ecosystems. To take a look at the seasonal variability in colour signals from a wide selection of European land use check out the dedicated web site that we have built here. Interestingly, Banksy may not have had this particular research application in mind when he was inspired to paint his crude oil painting No. 12.

Interpreting plant functional response to climate change using the anatomical and chemical signals of plant cellulose ♦  Rapid changes in weather experien_DSC6748ced by plants are recorded very clearly in their growth patterns during the season and their stable carbon and oxygen isotope composition. When plant material is cut carefully under a microscope it is possible to delve back in time and learn about how a plant has responded to the environment at incredibly high-resolutions of a couple of weeks in grasses and tree rings, or decades to centuries in the case of slow-growing sphagnum moss banks. With colleagues and many collaborators across Europe and other far-flung locations we have started to pull together a fascinating dataset of how wood density and the carbon (13C/12C) and oxygen (18O/16O) stable isotope ratios archived in cellulose vary with photosynthetic activity and transpiration rate, and in very contrasting climates. This dataset is now being used to test our understanding of wood formation and carbon allocation with a state-of-the-art soil-vegetation-atmosphere model called MuSICA developed in our team by Jérôme Ogée.

Investgating the link between forest canopy microclimate and variations  in the phyllosphere community ♦  Understanding patterns and processes controlling carbon (C) and water budgets across a broad range of scales, requires a knowledge of the explicit links between canopy microclimate, physiology and phenology. The current generation of land-atmosphere models are capable of predicting withwp_20160801_11_15_12_proin canopy microclimatic variability. However, very few datasets exist to validate such model outputs either spatially or temporally, as measuring physiologically important variables such as leaf temperature (Tleaf) and gas exchange is logistically challenging. These constraints also restrict potential opportunities to link leaf-cycle variations and the ecology of organisms living within canopies to present and future climates. Variations in within-canopy microclimate  provide a diverse range of habitats for the micro-organisms inhabiting the phyllosphere. The phyllosphere is the microbial habitat at the interface between the plant and the atmosphere and have an important role on plant function and the C and water cycle. With colleagues in BIOGECO we will quantitatively link phyllosphere community structure to environmental drivers and leaf function in the Ciron valley.
