My research is centered in the theoretical framework of evolutionary ecology, population biology and behavioural ecology. My projects aim at understanding life history variation in order to determine the adaptive and evolutionary processes that explain and maintain animal diversity. I´m particularly interested by three kinds of life history traits linked to behavior: cooperation, animal communication and maternal invesment. I'm mainly using birds as biological models. I'm mainly using empirical methods, including large-scale experiments and analyses of long-term data sets on different populations of passerine birds in the field.

I'm currently working on four main projects. 1) Evolution of colour ormentation in birds(with a special focus on female coloration and blue tits) 2) the cause and life history traits consequences of cooperation in sociable weavers ; 3) Sexual and social evolution on islands, and 4) the evolution of weaver nests.

I'm also part of  the Arts-Sciences project Obô and the association https://plumesetracines.net/

* Evolution of female colour ornementation

In this project we use a combination of empirical and comparative approaches to address three fundamental questions on sexual and social selection in both monomorphic species and dimorphic species in which females present conspicuous traits. Our questions are the following (i) Are female conspicuous traits under sexual /social selection ? (ii) Do female conspicuous traits reflect female quality and which mechanisms maintain signal honesty? (iii) What are the population consequences of female signalling and mutual sexual selection.

 * Evolution of plumage ornement in space and time

Selection often varies in space and time and long-term research that spans broad spatial scales is needed to understand the factors driving phenotypic variation and to assess the links between traits and fitness.  To assess the importance of spatiotemporal variation  and its consequences on selection estimates, we collected data on two study systems: (i) the blue tit (yellow and UV-blue colorationsmeasured by spectrophotometry since 2005, 600 birds measured each year); (ii) the  size of the sociable weaver melanin patch  since 2010 (the bib patch is photographied each year on 400 individuals)

           Website: https://sociableweaverproject.com/

The project aims at understanding the fitness bases of cooperation and the consequences of cooperation for population dynamics through its effects on reproductive output, survival and dispersal. Our study model is an endemic passerine bird from southern African passerine. This bird is a cooperative breeder. In cooperatively breeding species, mature individuals called ‘helpers’ assist the breeding pairs by bringing additional food to the nest. We work on the evolution of different cooperative behaviours – cooperative breeding, nest building and predator mobbing and on the relationship between cooperation, fitness, dispersal and long-term population dynamics.

Currently our project has two main aims: (i) determining whether sexual or social selection play a role in the evolution of cooperation and thus the role of partner choice ; (ii) determining  how presence / absence of co-operators affects maternal effects and parental investments

  3- Evolution on islands

             Website: https://islandbirdproject.com/

Islands are unique ecosystems sharing a distinctive set of characteristics that make them particularly interesting to study adaptation by organisms. The isolation and reduced area of islands result in simplified ecological ecosystems and an impoverished fauna that are expected to lead to convergent patterns of adaptation (the ‘insularity syndrome’). Our aim is to establish, using comparative work , whether island birds worldwide display such convergent shift for ornamentation, songs, behaviour and morphology. Then we aim at determining which factors lead to those changes and are particularly interested by the role of parasitism and interspecific competition. We worked on data collected in natural history museum and in the field (Sao Tome, Madeira, Gabon, Cameroun).

 THEMES DE RECHERCHE

Mes thèmes de recherche concernent la phylogénie, la phylogéographie et l'évolution moléculaire à partir de l'analyse des séquences de gènes mitochondriaux et nucléaires. L’objectif est de répondre, à l’aide de l’outil moléculaire, à des questions de biodiversité et systématique évolutive à l’échelle des vertébrés (mammifères, amphibiens et reptiles). Je m’intéresse aussi à l’échelle temporelle (datations moléculaires) des différents niveaux de diversifications ce qui permet de confronter les inférences moléculaires avec les données morphologiques, paléontologiques et biogéographiques.

Research interests

Dr Erwan Delrieu-Trottin joined the CEFE in 2021 as an Associate Professor from Ecole Pratique des Hautes Etudes. His research focuses on the origin and dynamic of biodiversity, working at the scale of species and populations. He works on the spatial and temporal dynamics of biodiversity by relying on traditional and next generation sequencing technologies. In the context of an unprecedented biodiversity crisis, the use of the molecular tool makes it possible to identify essential areas of conservation and to assess populations connectivity and the determinants of species assemblages. (e.g. environment, connectivity). He is particularly interested in tropical freshwater and marine fishes, which led him to work on projects related to different biodiversity hotspots, in the South Pacific (French Polynesia, Easter Island), South America, Indonesia and Africa.

Mon travail de recherche porte sur la description de la biodiversité, sur la compréhension des mécanismes à l’origine de cette biodiversité et sur son maintien au cours du temps à l’échelle des espèces et des populations. Je travaille donc sur la dynamique spatiale et temporelle de la biodiversité en m’appuyant sur des technologies de séquençage traditionnel (génétique) et de nouvelle génération (génomique & ADN environnemental). Dans le cadre d’une crise sans précédent de la biodiversité, l’utilisation de l’outil moléculaire permet d’identifier des zones essentielles de conservation et d’évaluer la connectivité des populations et les déterminants des assemblages des espèces (e.g. environnement, connectivité). Je m’intéresse particulièrement aux poissons tropicaux, d’eau douce et marins, ce qui m’a amené à travailler sur des projets portant sur différents hotspots de biodiversité, du Pacifique Sud (Polynésie française, ile de Pâques), d’Amérique du Sud, d’Indonésie et d’Afrique.

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 candidate - Macroecology

I am a PhD candidate working on macroecology, using citizen science data. Specifically, my PhD project aims to understand the sensitivity of birds to habitat changes.

Lien : HDR Xavier Morin

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.

Project: How much difference are Protected Areas making to the conservation of biodiversity?

Supervisor: Ana RODRIGUES

My PhD aims to understand the effectiveness of protected areas in conserving biodiversity, using bird monitoring datasets. Comparing spatially biodiversity inside and outside protected areas, I wish to understand which biodiversity metrics (abundance, richness, specialisation, rarity index, endemism...) are affected by the presence of protected areas across the globe and how.
