    Ph.D project:

    Sexual selection and the evolution of female ornaments:A study of female plumage colouration using comparative analyses and long-term data sets from blue tit populationDSC 6152 069s

    Supervisors:  Claire Doutrelant and Arnaud Grégoire

    Topic: My thesis focused on understanding the contribution of sexual selection in the evolution and maintenance of conspicuous colourations in female birds. 

    A first part tested how paternal care and female reproductive costs drove the evolution of female plumage colouration in songbirds, by the mean of a comparative study using spectrometry, avian visual models and life-history traits (Fargevieille et al. In prep).

     

    In a second part, a long-term project data set onblue tits (Cyanistes caeruleus) was used to test hypotheses related to the evolution of female ornamentation. Ten years of plumage colouration, from four populations were used to assess the evopairbluetitslution of female ornaments. Genetic correlation (Charmantier et al. 2017), relationships between colouration and survival rate or reproductive success (unpublished) were tested by the means of quantitative genetics, CMR analyses and within-study meta-analyses. Quantification of the degree of assortative mating at the population level - considering spatio-temporal variation - was also tested (Fargevieilleet al. 2017). It led to a more thorough study at the individual level trying to understand factors underlying assortative mating in ourpopulations (Fargevieille et al. In prep.).

    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).

    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 art-science project Obô.

    * 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)

    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

    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).

    Our aim is to work on one of the most spectacular and diverse radiations of extended phenotypes, the intricate and complex nest architectures of weaverbirds (family Ploceidae, 117 species in 16 genera), varying from the exquisite lace-like Malimbusnests to the rough thatch of the communally built sociable weaver nests . Our central aim is to investigate the role of sexual selection on the evolution and diversification of i) nest architecture (the extended phenotype) and ii) nest building behaviour (a potential associated display) and, for both traits, to determine how they relate to the classic ornaments in this group – striking colours, songs, and flight displays.

    Programme de recherche

    Depuis le début ma carrière de scientifique à Montpellier en 1989 mes recherches se placent toujours dans le cadre historique, bio-géographique et paysager particulièrement fascinant de la région Méditerranéenne et se focalisent sur l’écologie, l’évolution et la conservation de la flore.

    Dans cette région les changements historiques et contemporains pourraient avoir des conséquences profondes aussi bien pour la dynamique et la viabilité des populations et des communautés, que pour la capacité de réponse évolutive rapide des espèces, aspect scientifique trop souvent négligé. n élément clé dans mes recherches concerne mon investissement dans une recherche qui s'articule autour de collaborations interdisciplinaires très étroites (sciences humaines) et l'animation d'une interface fonctionnelle entre problématique scientifique et enjeux de conservation.

    Ces recherches s’articulent autour des thèmes suivants :

    • L’application de notre connaissance sur l’évolution de la flore à la conservation conservation du potentiel évolutif.
    • L’ évaluation de l’état de conservation des populations d’espèces rares, endémique où en limite d’aire.
    • La connaissance de la niche fine des espèces en tant que connaissance fondamentale pour la gestion de la flore.
    • L’analyse des interfaces entre connaissances écologique, perceptions culturelles et savoirs-faire locaux (notamment pour la cueillette) dans la conservation de la flore.

    Actuellement je mène des recherches dans le cadre du programme « Transitions écologiques et flore protégée : la gestion conservatoire à l’échelle de la niche (TRANECOL) financé par l’OFB et le CEMEB. Ce programme a pour but d’analyser la variabilité de la niche des espèces végétales protégées en situations de transitions écologiques où le fonctionnement des milieux est particulièrement contrasté en région méditerranéenne: en l’occurence la mosaïque de milieux côtiers où la micro-topographie et la salinité varie de manière très forte sur des espaces très restraints, les gradients d’altitude en arrière pays et sur les écotones entre grands types de substrat. L’objectif ici est d’informer les stratégies et actions des gestionnaires sur l’importance d’identifier la niche écologique des espèces à l’échelle très fine du fonctionnement des individus en milieu hétérogène.

    Notre travail se fait en étroite collaboration avec les gestionnaires dans trois contextes :

    • le territoire du Parc National du Mercantour,
    • la Réserve Naturelle Régionale de Sainte Lucie et d’autres sites sur le territoire du Parc Naturel Régional de la Narbonnaise en Méditerranée,
    • le site Natura 2000 de la Grande Maïre à Portiragnes dont la gestion est attribuée à la Communauté d’Agglomération Hérault Méditerranée et d’autres espaces de près salés sur le pourtour Méditerranéen.

    Plant Evolution in the Mediterranean

    My first book - Plant Evolution in the Mediterranean - was published in 2005. It provided the first synthetic account of the majors processes of evolution in the Mediterranean flora in relation to the history and ecology of the region. It analyzed patterns of species’ distributions and traits in the evolution of the remarkable diversity and degree of endemism that characterize the Mediterranean flora.

    CoverfrontminiEver since 2005 here has been an immense amount of new and fascinating work on the history, ecology, and evolution of the Mediterranean flora. During this time, human impacts have continued to increase dramatically, significantly influencing both the ecology and evolution of the region’s biota.

    My second book, Plant Evolution in the Mediterranean - Insights for conservation, published in 2020 represents a comprehensive update on these issues.

    This is not a traditional book on plant evolution, but rather a novel integration of a diverse and scattered literature to produce a synthetic account of Mediterranean plant evolutionary ecology that maintains the accessible style of the previous version but in a new structural framework. History, ecology, biogeography, and evolution are all set in the context of a dramatically increasing footprint. I argue how an understanding of the evolutionary ecology of the region’s flora can be used to provide insights into its conservation and management.

    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.

    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.

    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/

    The physiological responses of trees to water stress
     
    The mechanisms leading to acclimation or mortality of trees under global-change
    type drought

    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).

     

    Supervisors: Aurélien Besnard (DE, EPHE) & Alexandre Millon (MCF, HDR, IMBE).
    Co-supervised by Cécile Ponchon (CEN PACA).
