Research themes

My research aims to understand the role played by agrobiodiversity in the resilience of agroecosystems amidst global changes. I document changes in agrobiodiversity over time and analyze the interplay between their various drivers. Specifically, I investigate how (e.g., choices, seed supply and sources of information) and why (e.g., values, insurance effects) farmers manage, maintain, and experiment with various crop varieties. During my Ph.D., I focused on wine-growing systemscharacterized by significant but underutilized diversity of grape varieties. I employ an interdisciplinary approach in ethnoecology, at the intersection of ecological, agronomical, social and human sciences. I use a wide range of methods, including long-term fieldwork, surveys, modeling (R cran), GIS, social network analysis, and the mixing of qualitative and quantitative data.

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).

Thesis project: Urban imprint on marine biodiversity: an environmental DNA-based approach in the French Mediterranean

Coastal ecosystems, true mosaics of habitats, are major reservoirs of biodiversity, home to numerous species and supporting a wide range of ecological functions. However, anthropogenic pressures on these ecosystems are intensifying, particularly due to human population growth and its concentration on coastal areas. These pressures pose various threats to marine biodiversity, including pollution (chemical, plastic, noise, etc.), overexploitation of fishery resources, introduction of non-native species, and coastal artificialization. The replacement of natural substrates with artificial structures profoundly alters the heterogeneity of habitats, fragmenting and isolating them. Urbanization, defined as the transformation of space for the benefit of a single species, Homo sapiens, therefore does not spare the marine environment. While the same eco-evolutionary processes occur in “natural” and urban environments, certain phenomena are amplified or altered in an urban context, while others are more specific to it, due to the new interactions that arise when species that would not necessarily meet in their original habitat come into contact. Urbanization most often favors generalist species that are “pre-adapted” to disturbances, to the detriment of specialist species, leading to a change in the composition of communities along the urbanization gradient. At the regional or global level, these changes can be so marked that communities become more similar between urban areas, reflecting a phenomenon of biotic homogenization. Urbanization thus leads to a profound reorganization of assemblages and also has consequences at the intraspecific level: urban centers, often isolated from one another, generally exhibit strong genetic differentiation between populations and lower genetic diversity than external habitats. However, the increased connectivity of artificial marine areas via maritime transport can reverse these effects, promoting genetic circulation between populations. Nevertheless, most urban ecology research focuses on terrestrial environments. The marine biodiversity of artificial coastal areas, such as ports, remains largely unknown, and the ecological processes associated with urbanization in the marine environment have been little studied. One of the main obstacles to understanding these ecosystems is the lack of standardized, non-invasive methods capable of providing a comprehensive inventory of biodiversity. Environmental DNA (eDNA) metabarcoding is now a promising solution. This thesis therefore aims to fill the gaps in our knowledge of biodiversity in urbanized coastal areas, particularly ports, by using eDNA. It is based on data collected in the French Mediterranean – a region where artificialization has stabilized since the 1980s – and targets a wide variety of organisms, with a particular focus on fish communities. The thesis combines an assessment of the local effects of urbanization on assemblages, an analysis of biotic homogenization processes at the regional scale, an exploration of genetic variations within populations, and the development of methodological tools to model species occurrence and detectability. It thus makes it possible to characterize the impact of urbanization on marine biodiversity and to better understand the ecological processes that shape coastal communities in artificial environments.

PhD candidate

 

I'm a PhD student interested in developing statistical tools to model ecological process as reliably as possible. Especially I'm currently working with automatically processed sensor data. These data may come from camera traps, autonoumous recoring units for acoustic, or RFID tags. As these data are mass genereted, they are sometimes processed automatically by Deep Learning algorithms as Convolutional Neural Networks. However, using these DeepLearning outputs as error-free predictions and introducing them into ecological models can bias inferences. My objective is to propagate uncertainties from automated treatment of massive data into models in ecology.

I study visual communication at various scales: color perception, role of coloration in communication/camouflage, informative content of signals, evolution of signal design at large evolutionary scale. At the frontier between biology and physics, I study complex optical phenomena in birds and butterflies.

RESEARCH

I am interested in coloration and visual communication at various evolutionary scales. I characterize coloration and model its perception to assess the informative content of coloration, and identify the potential receivers of the communication process. I manipulate color signals in experiments to understand how receivers use coloration to reach their decision, in relation to other sensory modalities. At a larger evolutionary scale, I run comparative analyses to understand the parts of shared ancestry and selection in driving the evolution of coloration, to ultimately determine the adaptive functions that are fulfilled by coloration. I use different approaches (correlative and experimental designs, comparative analyses) and various biological models (birds, insects, mammals, amphibians) to answer functional and evolutionary questions.

At the interface between physics and biology, my recent work aims to understand the functions and evolution of transparency in butterflies and iridescence in birds. 

I study visual communication at various scales: color perception, role of coloration in communication/camouflage, informative content of signals, evolution of signal design at large evolutionary scale.

 Je travaille sur l’amélioration des méthodes de suivi des populations de plantes. Je me concentre particulièrement sur les deux principales sources d’incertitude des suivis de population : les plans d’échantillonnage et les erreurs d’observation. Selon les questions de recherche, j’utilise des approches expérimentales (tests sur le terrain) ou des approches plus théoriques avec des simulations informatiques.

Chargé de recherche à l’INSERM Ma principale activité de recherche porte sur l’évolution et la diversité taxinomique des macromycètes, que j’aborde via l’analyse phylogénétique d’échantillons issus d’un large réseau de mycologues européens partenaires. Je constitue aussi une extractothèque fongique destinée à mettre en évidence et valoriser le potentiel bioactif de ces organismes dans le domaine de la santé humaine. My research is mainly focused on the evolution and the taxonomic diversity of higher fungi. I am adressing this issue through the phylogenetic analysis of samples originating from a broad network of European partner mycologists. I am also assembling a fungal extract library, aiming at revealing and promoting the bioactivities of these organisms in the field of human health.   Courriel : This email address is being protected from spambots.

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.

PhD student – University of Montpellier

 

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.

Résumé :

Le changement climatique exerce une pression croissante sur les forêts du monde entier, et ses impacts potentiels sur la fécondité des arbres sont encore mal compris. De nombreuses espèces d'arbres forestiers se reproduisent suivant des patrons de fructification intermittente et synchronisée entre les individus, dits de masting, dont les déterminants complexes doivent être identifiés pour comprendre l'effet du climat sur la fécondité des arbres forestiers.

Cette thèse a comme objectif général d'approfondir notre connaissance des déterminants environnementaux de la fécondité des arbres forestiers et de leurs interactions, en se focalisant sur le chêne vert, une espèce très répandue en milieu méditerranéen. Elle a aussi pour objectif de déterminer comment la fécondité du chêne vert pourrait être affectée par le changement climatique, et de développer un modèle basé sur les processus capable de prédire cet impact.Ce travail de thèse a donc combiné des analyses de suivis à long terme dans une forêt de chêne vert soumise à une manipulation des précipitations*, des expérimentations de manipulation des relations sources-puits pour l'allocation des ressources à la reproduction à l'échelle individuelle, et de la modélisation.

J'ai montré que la reproduction était fortement régulée par les conditions météorologiques durant le cycle reproducteur, et en particulier par la disponibilité en eau en été-automne, et dans une moindre mesure par la disponibilité en carbone et nutriments ainsi que par la compétition entre fruits et nouveaux bourgeons. Mes résultats expérimentaux montrent que l'allocation de ressources à la reproduction peut être modifiée en cas de limitation des ressources par une défoliation ; et que les fruits en développement ont un impact négatif sur les dynamiques des réserves en azote et en zinc dans les branches ainsi que sur la production des fleurs femelles l'année suivante. Les observations en forêt indiquent qu'une réduction continue des précipitations sur plusieurs années induit une diminution du nombre de fruits produits, indépendamment des effets de la variabilité interannuelle et sans que les arbres semblent être capables de s'y acclimater. Enfin, j'ai développé, au sein du modèle de fonctionnement de l'arbre PHENOFIT, un modèle de fécondité se basant sur les hypothèses et résultats issus de mes travaux et de la littérature.

* Cette partie est basée sur l’analyse de données de floraison et de fructification collectées sur la station expérimentale de Puéchabon (http://puechabon.cefe.cnrs.fr/) depuis 1984, et qui offrent un recul très rare sur l’évolution des dynamiques de fécondité chez les arbres forestiers.

PhD Title:

Drivers of holm oak fecundity

Abstract:

Climate change is placing increasing pressure on forests around the world, and its potential impacts on the reproductive capacity of individuals are yet poorly understood. Many forest tree species reproduce following so-called masting patterns, in which seed production is intermittent and synchronized among individuals, whose drivers need to be identified in order to better understand the impact of climate on the fecundity of forest trees.

The general objective of this thesis is to deepen our knowledge of the environmental drivers of the fecundity of forest trees and their interactions, by focusing on the holm oak, a widespread species in the Mediterranean basin. It also aimed to determine how fecundity could be impacted by climate change, and to develop a process-based model capable of predicting this impact. This thesis work combines analyses of long-term monitoring in a holm oak forest exposed to a rainfall exclusion experiment*, experimental manipulations of source-sink interactions involved in the resource allocation to reproduction, and modelling.

I have shown that reproduction was strongly regulated by weather conditions during the reproductive cycle and in particular by the water availability in summer-autumn, and to a lesser extent by the availability of carbon and nutrients, as well as by competition between fruits and new buds. My experimental results show that the allocation of resources to reproduction could be modified in case of resource limitation due to defoliation; and that developing fruits have a negative impact on the dynamics of nitrogen and zinc reserves in branches, as well as on the production of female flowers the following year. Long-term observations show that multi-year rainfall reduction induce a decrease in the number of fruits produced which is additional to the interannual variability and that tree reproduction does not acclimate to drought. Finally, within the PHENOFIT model, I have developed a fecundity model based on the assumptions and results from my work and from the literature.

*Data analyzed in this project were mainly collected at the Puéchabon long-term monitoring site: http://puechabon.cefe.cnrs.fr/

PhD candidate – EPHE, IMBE, CEN PACA

 

Long-lived predatory birds ecology, demography and movement.

I am interested in the population dynamics of long-lived (seabirds and raptors). I study how demography and behavioural mechanisms such as movement are influenced by inter- and intraspecific relationships and the environment (climate, weather, habitat). The aim of my PhD thesis is to investigate the relationship between individual movement and demographic variability in the French population of the Bonelli's eagle (Aquila fasciata).
