    My research focuses on movement ecology: I study the factors influencing animal movements (especially dispersal) and gene flow, with a particular emphasis on landscape composition and structure. I also study how human-triggered landscape modifications like fragmentation affect animal movements; and the consequences on population functioning and structure. My research is hence tightly linked to the management/conservation of populations, and to landscape management (e.g. connectivity restoration, french Trame Verte et Bleue policy).

    Thèmes de recherche

    (English follows)

    Mes travaux cherchent à parvenir à une meilleure compréhension du déterminisme de la diversité végétale aux différentes échelles spatiales et temporelles, sa réponse aux changements futurs, et son rôle dans le fonctionnement des écosystèmes forestiers. En particulier, je cherche donc à comprendre et prédire comment la biodiversité des écosystèmes forestiers s’organise selon différentes échelles spatiales, comment elle sera modifiée par les changements globaux, et quelles en seront les conséquences sur le fonctionnement de ces écosystèmes. Pour ce faire j’essaie de développer une approche intégratrice basée sur les processus. Mes travaux se focalisent principalement sur les espèces d'arbres et arbustes. Pour mener à bien ces objectifs, j’utilise aussi bien des résultats issus d’expérimentation, d’observations le long de gradients écologiques in situ, et de modélisation.

    Plus précisément, mes travaux se déclinent selon deux axes majeurs :

    1-·Expliquer la répartition des espèces d’arbres et leurs patrons de diversité de l’échelle continentale à l’échelle locale.

    Ces travaux cherchent à identifier et comprendre quels sont les processus écologiques impliqués dans la limitation géographique actuelle des espèces d’arbres et quelle sera leur réponse au changement climatique, pour ainsi mieux modéliser la répartition des espèces en fonction des conditions environnementales via une approche mécaniste. De plus, j’ai étudié le lien entre la stratégie écologique des espèces ligneuses de la zone tempérée et leurs caractéristiques de répartition, dans un contexte évolutif. Enfin, au cours des dernières années, je m’intéresse aux mécanismes et facteurs qui régissent la coexistence des espèces à l’échelle locale.

    2- Expliquer la relation entre diversité spécifique et fonctionnelle des ligneux et productivité forestière, et prédire comment cette relation sera affectée par les changements environnementaux à venir.

    Ces travaux se focalisent sur l’étude du lien entre diversité (taxonomique, fonctionnelle, phylogénétique, en inter-spécifique mais aussi en intra-spécifique) et fonctionnement des écosystèmes forestiers, notamment leur productivité, en fonction de gradients climatiques. En particulier, la recherche des processus écologiques sous-tendant les phénomènes, qui constitue le fil conducteur de mes travaux, apparaît de plus en plus comme une façon plus appropriée et plus fiable pour rendre compte des dynamiques résultant de l’effet des changements globaux sur les espèces, les communautés et les écosystèmes. 

    Mes travaux reposent essentiellement sur deux types d’outils.

    • Suivi à long terme du fonctionnement de l’écosystème forestier : Gradient Méditerrano-Alpin de Placettes forestières (GMAP)

    Le dispositif GMAP est un réseau de placettes forestières distribuées le long de gradients climatiques (gradients latitudinaux nord-sud, gradients altitudinaux, en Provence et dans les Alpes) et différentes conditions de mélanges (en termes de composition de l’étage dominant de la canopée). Les forêts méditerranéennes et de montagne ont été choisies comme écosystèmes-modèles car celles-ci ont été identifiées comme particulièrement sensibles au changement climatique. Les placettes forestières (1000 m²) sont organisées par triplets, avec des peuplements purs et mélangés, situées le long de gradients environnementaux (régionaux et altitudinaux), pour explorer comment la productivité en bois, la régénération, et la décomposition des litières sont affectées par la diversité et la structure fonctionnelle des peuplements et les conditions environnementales. Les placettes sont distribuées le long d’un gradient latitudinal de 6 sites (pour le moment) entre Provence et Alpes du Nord, avec du Sud vers le Nord : la Sainte-Baume, le Lubéron, le Ventoux, le Vercors (Lente), et les Bauges. Chaque site comprend un gradient altitudinal de triplets de placettes (un peuplement mélangé avec le hêtre et une autre essence et les deux peuplements monospécifiques associés, celui de hêtre et de l’autre essence). Ce dispositif a été initié depuis 2012 grâce à divers projets (projets ANR BioProForet DIPTICC, projet BGF DISTIMACC - GIP ECOFOR, projet ERA-NET REFORM - SumForest), et a intégré l’OSU-OREME comme tâche d’observation long terme en 2018.

    • Modélisation

    Dans un contexte forestier où l’expérimentation s’avère délicate, le recours à la modélisation est un outil pertinent et prometteur pour explorer la relation diversité-productivité, dans la limite de nos connaissances actuelles des mécanismes régissant la dynamique forestière. Depuis plusieurs années je développe ainsi un modèle inter-échelles basé sur des processus pour répondre à des questions d’écologie des communautés et d’écologie fonctionnelle. Le but est d’abord de parvenir à un modèle permettant de faire des tests théoriques en forêts méditerranéennes et tempérées, mais de pouvoir ensuite obtenir un outil avec des portées opérationnelles.

    English:

    My research activities aim at achieving a better understanding of the processes driving plant diversity at different spatial and temporal scales, diversity response to on-going and future changes, and the role of diversity in the functioning of forest ecosystems. In particular, I therefore seek to understand and predict how the biodiversity of forest ecosystems is organized at different spatial scales, how it will be modified by global change, and what the consequences will be for the functioning of these ecosystems. To do this, I try to develop an integrative approach based on processes. My work focuses mainly on tree and shrub species. To achieve these objectives, I rely on experimental results and observations along ecological gradients in situ, as well as modelling.

    More precisely, my activities can be divided into two major areas:

    1--Explaining the distribution of tree species and their diversity patterns from continental to local scale.

    This work seeks to identify and understand the ecological processes involved in the geographical limitation of tree species and their response to climate change, in order to better model species distribution according to environmental conditions, through a mechanistic approach. In addition, I have studied the link between the ecological strategy of temperate zone woody species and their distribution characteristics, in an evolving context. Finally, I am interested in the mechanisms and factors that govern the coexistence of species at the local level.

    2- Explaining the relationship between specific and functional diversity of woody species and forest productivity, and predicting how this relationship will be affected by future environmental changes.

    This work focuses on studying the link between diversity (taxonomic, functional, phylogenetic, interspecific but also intra-specific) and the functioning of forest ecosystems, particularly their productivity, as a function of climate gradients. In particular, the search for the ecological processes underlying the patterns, which is the guiding principle of my work, is increasingly emerging as a more appropriate and reliable way to account for the dynamics resulting from the effect of global changes on species, communities and ecosystems.

    My work is essentially based on two types of tools.

    • Long-term monitoring of forest ecosystem functioning: Mediterranean-Alpine Forest Plot Gradient (GMAP)

    The GMAP design is a network of forest plots distributed along climatic gradients (north-south latitudinal gradients, altitudinal gradients, in Provence and in the Alps) and different mixing conditions (in terms of composition of the dominant canopy stage). Mediterranean and mountain forests have been chosen as model ecosystems because they have been identified as particularly sensitive to climate change. Small forest plots (1000 m²) are organized in triplets, with pure and mixed stands, located along environmental gradients (regional and altitudinal), to explore how wood productivity, regeneration, and litter decomposition are affected by stand diversity and functional structure and environmental conditions. The plots are distributed along a latitudinal gradient of 6 sites (for the moment) between Provence and the Northern Alps, with from South to North: Sainte-Baume, Lubéron, Ventoux, Vercors (Slow), and Les Bauges. Each site includes an altitudinal gradient of triplet plots (one stand mixed with beech and another species and the associated two monospecific stands, beech and the other species). This system has been initiated since 2012 through various projects (ANR BioProFor and DIPTICC projects, BGF DISTIMACC - GIP ECOFOR project, ERA-NET REFORM project - SumForest), and integrated OSU-OREME as a long-term observation task in 2018.

    • Modelling

    In a forest context where experimentation is difficult, modelling appears as a relevant and promising tool to explore the diversity-productivity relationship, within the limits of our current knowledge of the mechanisms governing forest dynamics. For several years I have been developing a cross-scaling model based on ecological processes to test hypotheses in community ecology and functional ecology. The aim is first to build a model that allows theoretical tests to be carried out in Mediterranean and temperate woodlands, but then to obtain a tool with operational scope.

    If you are interested by one of the aspects of these topics, please contact me.

    @Th_Lenormand

    My principal area of research is Evolutionary genetics and evolutionary ecology. I have a broad expertise in evolutionary biology, genetics and ecology.

    I have been working on adaptation and mutation, local adaptation, evolution of genetic systems (sex, recombination, sex chromosomes), evolution of gene duplicates, speciation, genetic conflicts, dispersal, biotic interactions (parasites, microbiota), statistics and fitness measures. I have been working with many empirical systems (vertebrates, insects, crustaceans, fungi, plants, helminths, bacteria), in the lab and in the field.

    Currently, my scientific activity rests on three axes: first I do theoretical work (theoretical population genetics, statistics, and bioinformatics development). I am particularly interested currently on the evolution of gene expression (on sex chromosomes or in asexuals). Second, I work on small crustaceans Artemia and Daphnia. I’m particularly interested currently on sex-asex transitions, biotic interactions and adaptation to temperature. Third, I do experimental evolution on E. coli. I'm particularly interested on testing fitness landscape models, adaptation to different doses of antibiotics, and coevolution of species coexisting by frequency dependence.
