Projet de thèse Année 2018

Ecole doctorale « Cerveau‐Cognition-Comportement » (ED 158 3C)
Titre du projet : Codage efficace et contexte sensoriel dans le système olfactif de l’insecte

L’olfaction est essentielle dans le déterminisme des traits de vie des insectes (reproductio n, alimentation, défense). Elle leur permet de s’orienter vers des sources d’odeur avec une efficacité unique qui contribue à leur succès adaptatif. C’est tout particulièrement le cas chez les papillons de nuit chez lesquels les performances du système olfactif impliqué dans la perception de la phéromone sexuelle sont remarquables en termes de sélectivité, sensibilité et rapidité. Les papillons de nuit mâles démontrent des capacités exceptionnelles de localisation de la source (femelles émettrice de phéromone) à grande distance (centaines de mètres), dépassant de très loin les capacités des meilleures technologies actuellement disponibles. La localisation d’une source d’odeur est pourtant une tâche extrêmement difficile car, en conditions naturelles, il n’existe pas de gradient de concentration qui puisse être utilisé et la détection des molécules odorantes est intermittente. En effet, le panache d’odeur est profondément modifié par les turbulences atmosphériques, il est constitué de filaments d’odeur de durée, intensité et espacement très variables et dont la statistique change avec la distance à la source [1]. Ainsi, la dynamique des détections d’odeur est la seule information sur la position de sa source. De plus, les signaux spécifiques que sont les phéromones sont perçus au sein d’un paysage odorant complexe, bruité et changeant, qui peut significativement affecter le comportement de l’insecte. Des composés volatils émis par les plantes (CVP) interfèrent avec la perception de la phéromone [2].

Malgré les progrès notables réalisés dans la description quantitative des fonctions du système olfactif de l’insecte [3], nous ne comprenons toujours pas comment l’efficacité du traitement des informations sensorielles peut se maintenir en dépit de la variabilité considérable des environnements
odorants naturels. Pour aborder cette question, ce projet de thèse vise à :
- Recréer au laboratoire des scènes olfactives réalistes sur les plans qualitatif (nature des composés, en particulier les CVP représentatifs d’un écosystème donné), quantitatif (concentration des constituants du panache) et dynamique (structure temporelle des puffs d’odeur).
- Enregistrer par des techniques d’électrophysiologie bien maîtrisées au laboratoire les réponses à différentes scènes olfactives de neurones des deux premières couches du système olfactif de l’insecte : i) neurones récepteurs olfactifs responsables de la transduction olfactive et ii) neurones du lobe antennaire, le centre primaire de l’intégration olfactive.
- Analyser comment le codage olfactif dépend du bruit de fond odorant. En collaboration avec L. Kostal (Dept de Neuroscience computationnelle, Institut de Physiology, Prague), une axe d’analysedes données électrophysiologiques sera basé sur l’hypothèse du codage efficace, un modèle théorique du codage sensoriel [4] (la représentation neuronale de stimuli sous forme d’émission de potentiels d’action). Selon cette hypothèse, les réponses nerveuses sont adaptées via des processus évolutifs pour encoder de façon optimale les stimuli de l’environnement naturel d’un organisme. Il s’agit d’une méthode générale pour aborder la question du codage nerveux.

Les objectifs de ce projet sont :
- L’analyse des performances de codage phéromonal (codage intensitif et temporel) à partir des réponses des neurones olfactifs périphériques et centraux.
- L’étude de l’ajustement de la précision de codage à la statistique de scènes olfactives réalistes.
- La mesure des effets d’environnement naturels de CVP sur le codage phéromonal.

La compréhension des capacités de codage du système olfactif des insectes représente un préalable indispensable à l’élucidation de leur(s) stratégie(s) d’orientation. Les enjeux socio-économiques de ce
projet concernent la lutte contre les insectes ravageurs et l’olfaction artificielle avec les robots traqueurs d’odeur.

3) develop analysis software to analyze large data sets
4) use and contribute to existing open source technologies by creatively solving problems and developing novel hardware and software solutions.

Our offer
• The doctoral candidate will be employed by TUM (65 % TV-L E13) for a total duration of three years (with possible extension).
• The student will benefit from ties to the LMU Munich, the MPI for Ornithology, the MPI for Brain Research, and the Institute of Neuroinformatics, Zurich.

We are looking for a motivated and competent candidate for a PhD thesis

Effects  of  prenatal  stress  on  personality  and  group  level  behaviour  of juvenile mound building mice
Context.  Stress  experienced  by  mothers  during  pregnancy  has  the  potential  to  modulate  the  offspring’s behavioural  and  physiological  development.  The  effects  of  maternal  stress  on  offspring  phenotype  might  not necessarily  be  pathological  but  can  adaptively  adjust  the  offspring  to  challenging  environments.  For  example, pregnant  females  experiencing  social  stress  during  high  population  density  may  produce  offspring  with behavioural  types  being  well  adjusted  to  cope  with  such  high  density  situations.  The  resulting  differences  in offspring behavioural phenotype can have functional consequences at the individual level - but also at the level of the sibling group, for example when littermates interact in a collective task necessary for their survival.
Study species.  In the mound building mouse (Mus spicilegus), juveniles from the same  litter  collectively build a large mound of soil and plant material in autumn. These mounds are essential for winter survival, as the juveniles stay in tunnels and burrows underneath, well protected from humidity and low temperatures. Presumably under high density  situations,  different  sibling  groups  can join together  to  build the  mound collectively  (mixed-litter groups). First studies of our research team show that individual variation in the transport of mound building items are associated with an individual‘s personality type.
Research questions. In the proposed project, (i) the effects of maternal social stress on offspring personality and its consequences on the individual transport performance will be studied. (ii) At the group level, it will be studied how  the  distribution  of  personality  types  within  a  group  of  siblings  affects  the  transport  performance  during mound building. (iii) Do prenatally stressed mixed-litter groups differ in transport performance from mixed-litter groups stemming  from non-stressed mothers?  It might be predicted that offspring from stressed mothers are particularly efficient to perform in mixed-litter groups.  (iv)  Do single-litter or mixed-litter  groups from stressed mothers perform better under challenging environmental conditions (i.e. under an increased predation risk) than single-litter or mixed-litter groups from non-stressed mothers?
Methods. Pregnant females will be stressed by repeated social confrontations. Offspring personality types will be determined  by  repeated standardized  behavioural  tests.  Individual differences in physiological stress responses will be quantified by infrared thermography and via faecal and serum corticosteroid levels.  Individual and group level  transport  performance  of  mound  building  items  will  be  quantified  in  experiments  under  laboratory conditions using RFID-based data loggers.  An increased predation risk will be simulated  by  the  presentation of predator odour. Data analysis will be performed by multifactorial statistical modelling.
Candidate. The successful candidate (with a Master in ethology, behavioural sciences or in a related field) should have experience in animal experimentation, preferably with  mammals,  and should have a good level of English.
Knowledge in applied statistics (with R, SPSS etc.) will be advantageous.
Supervision. Prof. Heiko G. Rödel, Laboratoire d’Ethologie Expérimentale et Comparée (LEEC), Université Paris 13,

Procedure.  Applicants will be pre-selected based on their qualifications.  Please send a short CV  (incl.  marks  of licence/bachelor and master, and names  +  contact data  of 2 referees)  and  a  letter of interest by email to H.G. Rödel before/until the 07 May 2018. Do not hesitate to request further information by email or by phone.
The  chosen  candidate  will  then apply with this  project to  the  Ecole  Doctorale Galilée  (Université  Paris 13)  for funding of a 3-year contract.  Candidates should be willing come in person for the interview by the Ecole Doctorale (in late June). The thesis will start in September 2018.

PhD position - Functional genomics of sperm competition in zebra finches - Bielefeld University

PhD position in Evolutionary Ecology and FunctionalGenomics
One PhD position in evolutionary ecology and functional genomics is available at the Faculty of Biology at Bielefeld University in the EvolutionaryBiology group (with PD Dr Tim Schmoll, see http://www.uni-bielefeld.de/(en)/biologie/Evolutionsbiologiein collaboration with the Department of  Animal  Behaviour  (with  Dr  Peter  Korsten,  see  http://www.unibielefeld.de/biologie/animalbehaviour). The position is available immediately for 36 months and is funded by the German Research Foundation (DFG) within the recently approved collaborative research  centre  (SFB/TRR  212)  entitled:  A  Novel  Synthesis  of  Individualisation  across Behaviour,  Ecology  and  Evolution:  Niche  Choice,  Niche  Conformance,  Niche  Construction (NC3).
The goal of this project (project B04 of the collaborative research centre) is to test how male Zebra Finches conform to their social niche as set by the prevailing level of sperm competition.
This  will  allow  us  to  understand  how  individual  variation  in  sexual  competition  generates individual  variation,  and  covariation,  in  both  competitive  traits  and  parenting  behaviour.  The successful  candidate  will  closely  work  together  with  another  PhD  student  to  (i)  quantify  male
social  niche  conformance  by  analysing  adjustment  of sexual  competitiveness  including behavioural (e.g. aggression) and ejaculate (e.g. sperm motility) traits; (ii) identify the underlyingmechanisms of social niche conformance on the hormonal (via endocrinological profiling) and the  gene  expression  (via  RNAseq)  levels;  (iii)  assess  the  adaptive  significance  of  niche conformance  under  a  niche  match/mismatch  paradigm;  and  (iv)  test  for  trade-offs  between investment in sexual competitiveness  versuspaternal care. A sub-project A will primarily focus on male  social  niche  conformance through  adjustment of behavioural traits and the  hormonal mechanisms underlying niche conformance. A sub-project B will primarily focus on male social niche conformance through adjustment of ejaculate traits and the gene expression underlying niche conformance. Note that the position offered here is exclusively for sub-project B.
The collaborative research centre:The position will be embedded within a larger collaborative research centre (SFB) comprising 18 principle investigators, 8 postdocs and 16 PhD students based at Bielefeld University, the University of Münster and the University of Jena. The aim of the  SFB  is  to  produce  a  conceptual  and  empirical  synthesis  of  individualisation  across behaviour,  ecology  and  evolution.  The  SFB  will  provide  exceptional  opportunities  for interdisciplinary  collaboration  and  academic  networking,  together  with  structured  training, scientific exchange and early career support programmes. Full details of the SFB can be found at www.uni-bielefeld.de/biologie/crc212.

Descriptif    du    sujet    :
Les    changements     globaux     actuels     induisent     des     variations     rapides     de     l’environnement   
auxquelles    les    individus    doivent    s’adapter    sur    une    échelle    de    temps    réduite.    En    particulier,    avec   
l’urbanisation    rapide    de    ces    dix    dernières    années,    la    ville    est    devenue    un    environnement    original   
avec     de     nouvelles     pressions     évolutives.     L’objectif     de     ce     projet     est     de     comprendre     les     effets   
directs    et    indirects    de    l’urbanisation    sur    les    individus,    puis    ses    conséquences    sur    les    populations.   
Ce    projet    se    focalise    sur    les    réponses    comportementales    et    physiologiques    à    l’urbanisation,    ainsi   
que    leurs    conséquences    en    terme    de    valeur    sélective    chez    les    oiseaux,    modèle    d’étude    privilégié   
car    différentes    espèces    sauvages    se    sont    installées    en    milieu    urbain.
Ce     projet     reposera     sur     une     approche     allant     de     la     physiologie     au     comportement,     et   
s’appuiera    sur    la     complémentarité     entre     une     approche     d’écologie     urbaine     utilisant     le     gradient   
environnemental    créé    par    l’urbanisation    (e.g.    pollutions,    température,    végétation,    fragmentation   
de     l’habitat)     et     une     approche     comparative     à     l’échelle     régionale     avec     une     population     rurale   
forestière.     Ce     projet     bénéficiera     des     suivis     biodémographiques     de     populations     de     mésanges   
bleue    (Cyanistes    caeruleus)    et    charbonnières    (Parus    major)    établies    depuis    2012    dans    les    parcs   
de    Paris    et    Rueil-Malmaison,    et    depuis    2010    en    forêt    domaniale    de    la    Commanderie    (77).
Les    questions    fondamentales    étudiées    au    cours    du    projet    doctoral    seront    :
1.  Impact     de     l’urbanisation     sur     la     communication     acoustique,     la     synchronisation     des   
activités    au    sein    du    couple    et    le    stress    physiologique
Chez     les     oiseaux     monogames,     mâle     et     femelle     synchronisent     leurs     activités     lors     de     la   
reproduction,    notamment    grâce    à    la    communication    acoustique,    qui    sera    ici    étudiée    grâce    à    des   
enregistreurs     automatiques     placés    dans     les     nichoirs.     Cette     approche     de     suivi     comportemental   
sera    associée    à    un    suivi    physiologique.    Le    milieu    urbain    est    susceptible    de    modifier    le    niveau    de   
stress     physiologique     (mesuré     grâce     à     différents     paramètres    :    stress     oxydatif,     stress     hydrique,   
télomères,    ratio     hétérophiles/lymphocytes),     la     réponse     fonctionnelle     de     l’axe     hypothalamushypophyse-surrénale    (mesurée    par    la    réponse    comportementale    au    stress    de    la    capture),    et    les   
conséquences     du     stress     (mesurées     par     la     capacité     à     développer     des     ornements   
sexuels=coloration     du     plumage).     Nous     explorerons     ainsi     les     corrélations     entre     urbanisation,   
stress    physiologique    et    communication/synchronisation    du    couple.
2.  Influence     de     la     communication     acoustique,     de     la     synchronisation     et     du     stress   
physiologique    sur    le    succès    de    reproduction    et    la    survie
La    qualité    de    l’incubation    et    du    nourrissage    des    poussins    ont    un    impact    essentiel    sur    le    succès    de   
reproduction.     Le     comportement     d’incubation     sera     suivi     grâce     à     des     enregistreurs     de   
température     placés     au     fond     des     nids     et    l’investissement     parental     de     nourrissage    grâce     à    des   
observations     comportementales     au     nichoir.     Les     communications     acoustiques     seront   
enregistrées    à    ces    deux    étapes.    Enfin,    le    succès    de    reproduction    sera    mesuré    avant    l’envol    par    le   
nombre    de    poussins    envolés,    et    leur    condition    physique    et    physiologique.    La    survie    des    adultes   
reproducteurs    ainsi    que    celle    de    leurs    poussins    sera    déterminée    grâce    à    des    modèles    de    Capture-Marquage-Recapture.

Offre de stage Master 1

Study of the self and the other in social heterospecific cognition in horses:
study of the sensitivity of the horse to the body orientation and the faces of others when using visual signals

Horses appear to be sensitive human attentional states (Proops & Mc Comb, 2010) and able to read human bodily attentional signals including body and head orientation and subtle eye cues (Proops and McComb 2010, Krueger et al. 2011; Maros et al. 2008; Sankey et al. 2011).
Yet little is known how far horses are using these attentional cues to adapt their behavior. A recent study (Ringhofer M. & Yamamoto, S, 2017) suggest that horses alter their communicative behaviour towards humans in accordance with humans’ knowledge state suggesting that horses possess some cognitive basis for this ability of understanding others’ knowledge state in social communication with humans.
Moreover, how horses understand what humans see or not is yet unclear (the visual field of humans and horses are quite different).
In this study we aim at investigating how horses adapt their communicative behavior to the attentional state of humans.
The items will be:
·      Identify the communicative cues of the horses (body language, mimicking) for asking for food they cannot reach by themselves
·      Investigate if horses adapt their communicative behavior to human attentional state
·      How horses understand what humans see or not
·      Investigate the feasibility of using FNIRS spectroscopy to investigate brain activities and cognition in horses
The research will be conducted at the Université libre de Bruxelles, Faculty of Medecine with the collaboration of the Haras du Chaimont (1460 Ittre, Belgique).
 The duration of the study will fit with a master I research stage of 6-8 weeks. Start: ASAP.
