Depending on the evolution of the sanitary crisis, a part of the internship could be performed remotely but, as far as possible, this solution will be avoided.Internship grant -554.40 €/month.Application deadline:30/11/2020. Application should include (i) a cover letter, (ii) curriculum vitae, and (iii) the contact details of two references. This should be sent as a single pdf at marielle.thomas@univ-lorraine.frand thomas.lecocq@univ-lorraine.frContext Aquaculture is the farming of aquatic organisms through several different practices (i.e. monoculture/polyculture, outdoor/indoor, flow-through systems/recirculated systems and extensive/intensive). Since the 1960s, aquaculture production has rapidly expanded and exponentially grown worldwide as far as to provide more than 50% of the world’s aquatic food consumption nowadays. Aquaculture has thus become a key factor in human food security. However, it is facing major challenges that will be even more important in the next decades. Indeed, sustainability and resilience of current aquaculture production raises concerns. For instance, intensive monoculture based on few species has often (i) significant environmental negative impact, (ii) low ability to withstand competition and disease/pest attacks, and (iii) a low adaptation potential facingto changes in environmental and socio-economicalcontexts. Polyculture in fish production is a long-standing practice,which has been somewhat disregarded in recent aquaculture development in some parts of the world, especially in a production intensification option. Yet, it can avoid some of the drawbacks of fish monoculture.Indeed, there is growing evidence that species diversity contributes to the production system resilience in the context of economic changes, improves farminputs’ utilization, and decreases the amount of waste by the recycling of co-products of some taxa by the other co-farmed species. Nevertheless, such benefits can be reached only when a relevant combination of species is used. This can be achieved by designing fish community based on species compatibility (i.e. species can live in the same farming environment without detrimental interactions) and complementarity (i.e. complementary use of available resources and/or commensalism/mutualism).This one of the aims of the SEPURE project (i.e. « Nouvelles stratégies de construction et de conduite de systèmes de production en étang pour une pisciculture durable») in which scientists (6 research units, INRAE) and fish farmers work together to achieve sustainable and efficient aquaculture.Work Evaluating species compatibility requires first to assess whetherdifferent species can live in the same abiotic environment (e.g., by considering pH, temperature, water current, etc.). The engineering or master student will perform this assessment with the researchers of the University of Lorraine. She/he will develop ecological niche modelling(ENM)for 50 fish species that have been pointed out by aquaculture stakeholders as relevant for the tomorrow’s fish farming in outdoor production. First, she/he will be involved in the selection of relevant abiotic parameters for fish ENM by consideringparameters available in databases(e.g., https://www.earthenv.org/streams). Second, the student will develop abiotic parameter and species occurrence datasets through geographic information system (GIS) application. Third, she/he will analyze these datasets to determine the niche position and niche breadth

for each species via outlying mean index (OMI) analyses. Multivariate analyses (e.g., MANOVA) will be used to test for significant differences in the mean niche values of species.This step will provide useful insights on the species compatibility. Fourth, ENM will be developed (e.g., boosted regression tree method) for each species. These ENMs will be projected across Europe or the World (depending on the species considered) for current and future climate.This step will provide pieces of information about how the species compatibility could change according to fish farming locations and climate changes.The last step willbe to determine what fish community will be the best for fish farming under a given abiotic niche. Profile-We are looking for highly motivated and rigorous engineering or master student (master 2, only). The candidate is expected(i)to search, read,and understand scientific literature including in English, (ii) to have team skills, a sense of responsibility, and(iii)to havegood skills in GIS and core skills in statistical data analyses(in R language).References1.Lecocq, T., Harpke, A., Rasmont, P., and Schweiger, O.

Stage M1 2mois

 

Dessine-moi un Mouton : Apprentissage et évolution du Dessin chez les Hominidés

 

Nous recherchons un stagiaire, de préférence M1, pour un stage de 2 mois sur ce sujet.

 

Résumé : Dès l’enfance, l’être humain s’exprime à travers différents comportements artistiques tels que le dessin. Ce dernier a également été rapporté chez d’autres animaux, nos plus proches cousins, les grands singes. L’analyse du dessin est un domaine de recherche actif, notamment en psychologie et en anthropologie, pour en comprendre le développement et l’évolution. Cependant les mesures reposent sur des critères subjectifs et/ou sur la nécessité d’un échange langagier. Ces critères sont discriminants, étant donné que les plus jeunes enfants ou ceux présentant certaines psychopathologies ne seront pas en mesure de s’exprimer sur leurs productions. La même conclusion est établie pour d’autres grands singes. Y a-t-il des intentions ou d’autres caractéristiques présentes dans le dessin, même non figuratif, que nous ne décelons pas ? Pour répondre à cette question, des indices objectifs d’analyse fractale ou encore basés sur le nombre de couleurs utilisées ont permis de mettre en lumière des différences entre les groupes étudiés : chimpanzés – humains ; enfants – adultes. Cependant, ces résultats sont limités. En effet, ces analyses ont été faites sur seulement quelques centaines de dessins et les résultats ne permettent pas de différencier des classes d’âge proches. Afin d’aller plus loin dans la différentiation des dessins, des algorithmes de Deep Learning (réseaux de neurones) seront développés pour identifier de manière plus précise les patterns de chaque groupe et ainsi expliquer sur quels aspects reposent ces classifications. Cette avancée méthodologique permettra d’approfondir objectivement notre connaissance du comportement de dessin d’un point de vue phylogénétique et ontogénique.

 

Tâches du stagiaire : Collecte de données, analyse morphométrique des dessins, gestion d’une base de données, analyses statistiques.
