Cyril Firmat,

Post-doc ANR MECC

Cyril Firmat

The general aim of my work is to investigate how much the genetic architecture of complex phenotypes is able to predict micro- and macroevolution. I combine quantitative genetic approaches (pedigree- and artificial selection-based and association genomic approaches) with comparative methods, often in relation with mathematical and numerical models of evolution. Currently, my specific aim is understanding the evolutionary dynamic of leaf phenological traits and their reaction norms in a metapopulation of white oaks spread along a broad environmental range. My work is funded by the ANR project MeCC.

Guillaume Charrier,

Post-doc LABEX COTE

Guillaume Charrier

I am a plant ecophysiologist which research interest is to study the impact of abiotic stresses on plant distribution through physiological drivers. Hence, I used experimental results to explain, develop concepts and model the processes related to frost vulnerability (e.g. carbon balance, phenology, hydraulic conductivity) and how it impacts tree distribution. I currently work on the impact of drought stress on grapevine in collaboration with ISVV (UMR EGFV), UMR Biogeco and UMR ISPA.

Noelia Gonzalez Muñoz,

Postdoctoral Researcher

Noelia Gonzalez Muñoz

Noelia joined the lab in May 2015, thanks to an AgreenSkills postdoctoral fellowship, after finishing her first and itinerant postdoc at Universidad Rey Juan Carlos, Universidad de Alcalá, Université Paris-Sud and INRA-Bordeaux. She has a strong background in ecology, ecophysiology, invasive trees, climate change and ecological modelling. Her current project aims to assess the main drivers of drought induced conifer mortality from global to plant scales, combining spatial modelling and experimental approaches.

Laurent Lamarque,

Postdoctoral Associate

Laurent Lamarque

Laurent will rejoin the lab in January 2016. He completed his master’s degree in the lab in 2006 before crossing the Atlantic Ocean to deepen the study of invasive maple trees and complete his Ph.D. at York University, Toronto in the lab of Chris Lortie. He moved to Northern Quebec in 2013 to work on protection and sustainable development projects of the boreal forest (http://www.faunenord.org/), before joining the lab of Esther Lévesque at the Université du Québec à Trois-Rivières in 2015 as a postdoctoral associate to work on the shrubification of the Arctic. Laurent’s interests lay at the crossroads of plant ecology, ecophysiology and evolutionary biology. His research in the lab will be funded by the IdEx Bordeaux programme (http://idex.u-bordeaux.fr/) and will be cosupervised by Greg Gambetta from the Institut des Sciences de la Vigne et du Vin (http://www.isvv.univ-bordeauxsegalen.fr/en/).Laurent’s publications (per ResearchGate) https://www.researchgate.net/profile/Laurent_Lamarque2/contributions

Pauline Bouche

After completing my master thesis at Sylvain Delzon lab, I integrated Ulm University in Germany for a joined PhD thesis. I was supervised by Steven Jansen in Germany and Sylvain Delzon in Bordeaux. I studied the functional role of torus-margo pits in the xylem of conifers and the variability of cavitation resistance at the inter-specific level and within a tree.

Sujet de thèse
Tree population responses to climate change: monitoring reproduction into the wild.
Activités de recherches
Key words: Trees’ reproduction – Masting – Fitness – Gradient of selection – Climate change
Phenology is a sensitive biosphere indicator of climate change. Although changes in vegetative phenology have considerable consequences for ecosystem functioning (Keeling et al 1996), we lack information on the response of reproductive phenology in forest trees to climate change. Yet, reproduction is one of the most important traits in determining plant fitness. Because the flowering and fruiting phenology of plants is sensitive to environmental cues such as temperature and moisture (Piovesan and Adams, 2001; Richardson et al 2005), climate change is likely to alter patterns of reproductive traits (Hedhly et al 2008).
My Ph.D. focuses on the ways that trees respond to environmental changes by understanding the sensitivity of reproduction to temperature. In order to figure out this, my interests lie at the intersection of functional ecology and evolutionary biology. I am interested in both the mechanisms that drive trees’ reproduction by studying masting process under climate change, and the genetic and phenotypic variability of several reproduction traits along environmental gradients.
Since 2014 I’ve been a Ph.D. student at INRA – UMR Biogeco and Bordeaux University in Ecology. I’m co-advised by Sylvain Delzon and Antoine Kremer.

Brief introduction of PhD work
I Joined Sylvain Delzon’s lab in 2014 to do my PhD under his supervision. Anabel Porte and Christophe Plomion are my co advisors. Ecophysiology, wood anatomy and genetics are the areas of my interest. The objective of my PhD project is to investigate the intraspecific variability in cavitation resistance in conifers including conifers from Pakistan as well as in several crop species such as sunflower. Rising global temperatures linked with climate change have enhanced drought induced tree mortality irrespective of the region of their existence affecting the global net primary productivity. The ability of woody plants to survive and recover from long drought spells is strongly associated with their ability to resist cavitation. The physiological and genomic basis of cavitation resistance are, therefore, of vital importance to understand the ability of woody species to transport water during drought events and predicting drought induced forest decline at regional and global levels. I am focusing xylem anatomy to find out anatomical traits linked with drought resistance. Quantitative Trait Locus (QTL) Analysis will be conducted to detect the genomic regions involved in cavitation resistance in maritime pine (Pinus pinaster).

Maximilien Larter

After completing my Masters here at Bordeaux University, I’m currently in the final stages of my PhD on the evolution of cavitation resistance in conifers (my advisers are Sylvain D. and Jean-Christophe Domec). I use phylogenies and various comparative methods to understand trait macro-evolution. I’m interested in particular in how climate has shaped the evolution of conifers (diversification patterns) and how this relates to cavitation resistance. I also have a soft spot for Australian conifers and spinning bits of them very (very) fast.
