    RESEARCH

    My research is framed around a comparative exploration of the role of multiple environmental drivers in shaping species distributions and diversity at multiple spatial and temporal scales. Most of my research is structured on the combined use of ecoinformatics methods (statistical analysis of large data sets) and naturalist expertise to understand empirical patterns of community composition in space and time. My main active axes of research include :  

    - functional biogeography of seabirds in the Southern ocean. I try to explain and predict the composition of seabird assemblages with spatial models calibrated with environmental factors, trophic interactions and species traits. The project relies on a large-scale bird counts protocol from ships and statistical model of multiple data types. See the C-BIRDS project and thesis.

    -  understanding spatial patterns of vertebrates distributions and assemblage compositions. Relying on various opportunistic or protocoled data sources at multiple spatial scales, I investigate the determinants of spatial patterns in vertebrate distributions and assemblage composition through spatial models based on proxies of historical and contemporary processes. See for instance he MALPOLONdatabase.

    - Ecoacoustics and community ecology. Several active projects focus on the relationship between bird community composition and the characteristics of soundscapes at multiple spatial and temporal scales, in order to explore the acoustic environment in which species interact and its changes with current land-use and climatic dynamics. See the ACOUCENEproject (2022 - 2025, FRB/CESAB)

    COLLABORATIVE WORK 

    Most of my interactions with biodiversity stakeholders are focused on data analysis to answer questions relative to the monitoring of human impacts on biodiversity at a regional or landscape scale.

    - Ecological data analysis. I am involved in initiatives to foster interactions between scientific and non scientific stakeholders with respect to data-based ecological monitoring and expertise. See the website of the CISSTATnetwork. 

    - Analysis of land use influences on common bird assemblages in southern France. I investigate the impact of land use and habitats on the temporal dynamics of local bird assemblages with opportunistic and protocoled data (collaborations with the Ligue pour la Protection des Oiseaux - PACA). 

    - Wildlife road casualties. I work with the Ligue pour la Protection des Oiseaux and the CEREMA to explain and predict spatial patterns in road casualites. We exploit jointly multiple sources of protocoled, non-protocoled and citizen science data to identify mortality hotspots and explanatory factors, with the final aim to inform public policies on the mitigation of traffic impact on vertebrates. See the final report of the COCPITT project (2020-2023).

     - Interacting imprints of climate change and land use on biodiversity. Using multiple taxa and scales, I investigate how species' responses to historical and present land use change interact with their responses to climate change. See the LANDBIO project (2022 - 2023, OFB - french ministry of ecology)

     

    TEACHING

    Most of my teaching activity is embedded within the program of the Ecole Pratique des Hautes Etudes.

    - Data analysis for ecologist : a three-weeks course dedicated to biodiversity stakeholders, framed on the practical use of statistical methods and the R software in ecological monitoring. 

    - Environmental law and policy : I drive a one-week course to introduce environmental public policies to scientific ecologists, involving speakers from various authorities and decision levels and practical training to improve students' written and verbal interactions with non-scientific stakeholders.

    - Methods for ecological monitoring : a two-weeks course with Aurélien Besnard, mainly dedicated to master students and biodiversity stakeholders, to improve their skills and critical thinking in advanced numerical methods for ecology, including species distribution modeling, population dynamics, sampling design and analysis of diversity indices.

    - Environmental changes and ecological science :I contribute to several courses on global changes and environmental monitoring. My teaching is focused on the interactions between science and society through several lenses including epistemology and governance / spatial planning.

    - processing bias (sparse coding, efficient categorization)

    - models of animal vision (colour vision, pattern recognition)

    - proximate mechanisms of mate choice

    - Methods: Artificial intelligence for neuroscience and evolutionary ecology

     

    Who am I?

    I am an evolutionary biologist, cognitive scientist and naturalist. My main objective is to understand how do evolve complex and extravagant visual signals such as the eyespots of the peacock, the danse of the birds of paradise, and some artworks in humans. My research hypothesis is beauty. Using approaches of empirical psychology, computational neuroscience, artificial intelligence and philosophy of aesthetics, my goal is to identify the biological mechanisms underlying the beauty judgment in order to develop mechanistic models that predict this judgement. I then transfer these models to other animals to understand how beauty influences behaviors and, ultimately, the evolution of communication signals in nature.

    I am also working on methods to characterize visual phenotypes, with applications in community ecology, evolutionary biology and systematics. I am particularly interested in how to use artificial intellgience to describe visual phenotypes and to model animal vision.

    I am also conducting or participating to several research projects in ornithology (mostly on searbirds) and ichthyology (fish, and in particular gobies, of the Northeastern Atlantic and the Mediterranean region).

    I’m a PhD student interested in animal behaviour and cognition, and how they translate into the spatial and demographic dynamics of populations. During my PhD, I focus on the interplay between individual movements and the dynamics of population networks through two case studies: 1) migratory connectivity and its relationship with the demography of migratory populations; 2) informed dispersal and its implications for the structuring and the stability of larid colonies. Linking individual and population-level processes leads me to draw on methods from both behavioural ecology and population biology.

    Mon objectif est de comprendre le rôle et l’importance des odeurs et des médiateurs chimiques dans le fonctionnement et l’évolution des relations plantes-insectes. Je m’intéresse particulièrement aux aspects suivants : quelles sont les caractéristiques des odeurs et des signaux chimiques disponibles pour les insectes ? Quelle est l’activité biologique de ces molécules (réponse comportementale des insectes) ? Dans quelle mesure et à quel(s) niveau(x) ces interactions chimiques jouent un rôle dans le fonctionnement et l’évolution des systèmes plantes-insectes ?

    Project

    The objective of this PhD project is to better understand how wild populations of great tits and blue tits are affected by urbanization and what mechanisms are involved in the observed phenotypic differences between urban and forest populations. This study will rely on the long-term population monitoring in urban and forest habitats established in Montpellier (CEFE TIT PROJECT) , as well as on comparative analyses with the city of Paris. The thesis will particularly explore physiological aspects that have not been studied thus far. Given the characteristics of the urban environment, which is more stressful and has higher temperatures, physiological adaptations to urban life are expected to be observed. Variations in the endocrine system between urban and forest environments will be studied, focusing on stress and reproductive hormones. Additionally, aspects of respirometry will be investigated, with the primary question being: do urban birds have a metabolism pre-adapted to high temperatures due to living in an urban heat island effect environment? In a second part, the project aims to dissect how urban phenotypic shifts are driven by genetic change or plasticity. To study this aspect, common garden experiments have been set up. Data from individuals raised under similar environmental conditions can be compared to wild individuals, thus observing whether phenotypic differences between urban and forest habitats are maintained or not.

    Thesis project: Climatic, anthropic and intrinsic determinants of ornaments expression and their association to fitness.

     

    Urbanisation and climate change are two major factors driving ongoign environmental changes in wirld populations worldwide. Research has revealed plastic and genetic responses to these anthropogenic changes. A shift in environmental conditions are expected to impose novel slective forces that can shape phenotypic variation of populations living in urban environments. Ornaments such as conspicuous colourations play a crucial role shaping interactions between individuals in inter and intra-sexual contexts. Ornamentals surch as feathers, with carotenoid-based (yellow to red), structural (blue) and melanic colours, are expected to be associated with variation in environmental conditions. Phenotypic divergences are known in urban environments, however understanding the underlying mechanisms driving colour variation are not investigated.

    This projects uses a long time dataset from the following of four blue tits populations, three in Corsica and one near Montpellier, and two great tits populations from the city of Montpellier and a nearby forest. Overall it covers 10 to nearly 20 years of colouration data. This dataset results from the work of numerous researchers and students from the CEFE TIT PROJECT.

    This thesis aims to:

    • Unravel the effects of urbanisation and climate change on carotenoid colouration in the great tits, and investigate whether phenotypic divergence has a temporal pattern.
    • Understand which urban characteristic is causing changes in bird colouration using
      1/ common garden experiments to see whether there is plastic or genetic changes.
      2/ metabarcoding data to see what urban and forest birds are eating while they renew their feathers.
    • Investigate selection by survival on coloured ornaments for both blue and great tits and compare it between environments.

    L’objectif général de la thèse est d’améliorer l'état des connaissances sur le lamantin d’Afrique (Trichechus senegalensis) au sein du Parc National de Conkouati-Douli (PNCD) afin de guider les actions favorables à sa conservation (sensibilisation, méthodes de pêche, activités alternatives, …) tout en prenant en compte les impacts socio-économiques. L’aspect cryptique et méconnu de cette espèce menacée d’extinction nécessite un couplage de différentes méthodes de suivi non-destructifs ni invasifs (observation visuelle, acoustique, génomique), dont certaines sont nouvelles (ADN environnemental). Ce suivi aura pour but, d’une part, de mieux connaître les besoins écologiques de l’espèce, son habitat, et sa distribution au sein du parc ; d’autre part, il permettra d’estimer des indices de l’abondance de la (ou les) population(s) de lamantin présente(s) au sein du PNCD. Finalement les résultats de ce projet permettront de proposer des mesures d’évitement, de réduction ou de compensation des menaces qui pèsent sur l’espèce tout en limitant les effets négatifs pour la population humaine locale.
     
    Objectif 1 : Caractériser la distribution de l’espèce en lien avec l’environnement (paramètre physico-chimiques, végétation, pressions anthropiques, …) et proposer un modèle d’occurrence au sein du parc et une cartographie.
    Nous chercherons à identifier les besoins écologiques de l'espèce au sein du PNCD, sa répartition en vue d'établir une carte de probabilité d'occurrence.
     
    Objectif 2 : Estimer la taille de la population de lamantins dans le parc grâce à la génomique.
    Nous analyserons la structure et la diversité génétique du Lamantin au sein de PNCD. Nous estimerons également un indice de taille de l'échantillon que nous avons.
     
    Objectif 3 : Apport de l’acoustique dans la caractérisation spatiale et saisonnière de l’habitat du Lamantin, la caractérisation des individus et l’apport pour un indice d’abondance en lamantins, et comparaison avec les résultats génétiques.
    Nous testerons la capacité de l’approche acoustique à identifier individuellement les lamantins ainsi qu’à obtenir une estimation de la taille de population. Les résultats seront comparés à ceux obtenus par le suivi génétique (Objectif 2).
     
    Objectif 4 : Proposer un programme de conservation et identifier les zones de protection prioritaire en interaction avec les populations pour en limiter les impacts socio-économiques.
    Nous utiliserons alors les connaissances acquises sur la répartition spatiale et l’abondance du Lamantin d’Afrique dans le PNCD (Objectifs 1, 2 & 3) pour guider les actions de conservation de l’espèce dans le parc.

    Thesis projet : Characterize the distribution and population size of the African manatee, a threatened species, in Conkouati-Douli National Park, Republic of the Congo
     
    The general objective of the thesis is to improve the knowledge about the African manatee (Trichechus senegalensis) within Conkouati-Douli National Park (CDNP) in order to guide conservation actions (awareness, fishing methods, alternative activities, etc.) while considering socio-economic impacts. The cryptic and poorly understood nature of this threatened species necessitates a combination of different non-destructive and non-invasive monitoring methods (visual observation, acoustic, genomic), some of which are new (environmental DNA). This monitoring aims to better understand the ecological needs of the species, its habitat, and its distribution within the park, as well as to estimate indices of manatee population abundance within the CDNP. Ultimately, the results of this project will enable the proposal of avoidance, reduction, or compensation measures for threats to the species while minimizing negative effects on the local human population.
     
    Objective 1: Characterize the species distribution in relation to the environment (physico-chemical parameters, vegetation, anthropogenic pressures, etc.) and propose an occurrence model within the park along with mapping.
    We will seek to identify the ecological needs of the species within the CDNP, its distribution to establish a probability map of occurrence.
     
    Objective 2: Estimate the size of the manatee population in the park using genomics.
    We will analyze the genetic structure and diversity of the manatee within the CDNP. We will also estimate a sample size index that we have.
     
    Objective 3: Contribution of acoustics to the spatial and seasonal characterization of manatee habitat, individual characterization, and contribution to a manatee abundance index, and comparison with genetic results.
    We will test the ability of the acoustic approach to individually identify manatees and to obtain an estimation of the population size. Results will be compared with those obtained through genetic monitoring (Objective 2).
     
    Objective 4: Propose a conservation program and identify priority protection areas in interaction with populations to mitigate socio-economic impacts.
    We will use the knowledge gained about the spatial distribution and abundance of the African manatee in the CDNP (Objectives 1, 2 & 3) to guide species conservation actions in the park.

J'ai pour objectif de caractériser l´impact de l’augmentation de polluants atmosphériques sur la rencontre entre espèces dans les interactions plantes-insectes et donc sur la résilience de ces interactions. J'étudie également les mécanismes évolutifs expliquant la nature des signaux chimiques ainsi que la détection de ces signaux dans les interactions plantes-pollinisateurs.

     

    I study the role of chemical mediation in the functioning of different types of plant-arthropod interactions. I aim at characterising the impact of increasing concentrations of atmospheric pollutants on the encounter between species in plant-insect interactions and hence on the resilience of these interactions. I also investigate the evolutionary processes explaining the nature of the chemical signals and how they are detected in plant-insect interactions.

    I am an evolutionary and behavioural ecologist broadly interested in understanding the causes and consequences of phenotypic variation in behaviour, life-history and physiology across different hierarchical levels of organization. In my current postdoc with Anne Charmantier and Sandra Bouwhuis I focus on the evolutionary genetics of phenotypic plasticityusing a long-term data set of common terns (Sterna hirundo) from the North Coast of Germany.
