Global change scenarios are valuable for guiding management and governance strategies, stimulating decision making, and increasing collective awareness of future biodiversity trends. The degree of realism and integration of ecosystem models used for this purpose is constantly improving, but they still often neglect the evolution of marine populations in future projections. However, marine populations adapt to global changes, either through phenotypic plasticity or evolution, through modifications of their biological characteristics such as life history traits, physiological and bioenergetic traits. The challenge of this thesis is to develop an ecosystem model that allows the exploration of biodiversity scenarios at intra- and inter-specific scales by explicitly representing the phenotypic plasticity of life history traits, their genetic variability, selection and evolution under the combined influence of fisheries and climate change, and the resulting genetic drift and loss of genetic diversity. Applied to the North Sea, this new model is used to understand the processes responsible for changes in life history traits, whether they are of plastic or evolutionary origin. On the one hand, the bioenergetic processes underlying plastic changes are studied by an original approach comparing the differences between the fundamental and realized thermal response curves for different species and life history stages. On the other hand, changes in life history traits are explored through an evolutionary lens by taking into account multiple selection pressures such as fishing, prey-predator interactions and climate change.The integration of plastic and evolutionary processes in ecosystem models allows to describe the inter-individual variability of biological traits and to understand their temporal trends observed in the marine environment. In this way, it responds to the crucial issue of credibility of intra- and inter-specific biodiversity projections under scenarios combining climate and fisheries. The integration of these processes will also allow to quantify more precisely the synergistic and antagonistic effects of these two pressures and to take into account the capacity of populations to adapt to global changes in order to estimate more reliably their resilience

Symbiotic interactions are a major driver of evolution. The symbiont genotype is able to alter the host phenotype, and the other way round: it is called "the extended phenotype". In this respect, Wolbachia endosymbiosis is remarkable. This intracellular bacterium is a well-known reproductive parasite able to induce feminization of genetic males or cytoplasmic incompatibility in its terrestrial isopod crustacean hosts. Currently, no molecular genetic basis of these reproductive manipulations has been described. In order to identify genes involved in feminization, we used an integrative approach that combines genomic, gene expression and phenotypic studies. We first analysed the molecular evolution of the homologous recombination pathway in Wolbachia genomes, an important source of genomic plasticity that can be linked with phenotypic diversity. Then, in order to perform comparative studies that will substantially improve the understanding of the molecular mechanisms of feminization, we established a system in which the feminizing strain wVulC feminizes two different isopod hosts (natural host: Armadillidium vulgare ; heterologous host Cylisticus convexus) that have a different sexual differentiation timing. Indeed, as feminization is thought to happen before or during sexual differentiation, it is important to distinguish the effect of Wolbachia due to sexual differentiation from that due to development. Finally, a gene candidate approach (from bacterial genome sequencing to comparative bacterial gene expression during host developement) allowed us to determine a reduced list of 29 genes (among the 1885 genes of wVulC) that have a high probability to be involved in feminization. The potential roles of these candidate genes as putative effectors of feminization induced by wVulC is then discussed. This work substantially contributes to the identification of putative endosymbiont factors that have an evolutionary impact on sex determination of their hosts

Wolbachia are intracellular alpha-proteobacteria vertically transmitted from mothers to their offspring through oocytes. As a consequence of this transmission mode, reproductive manipulation strategies that promote bacteria spread in host populations have been selected. The most common manipulation used by Wolbachia is called cytoplasmic incompatibility (CI). CI occurs when infected males mate with uninfected or incompatible Wolbachia-infected females and results in the death of offspring before hatching. CI is generally conceptualized as a mod/resc or toxin/antidote model in which paternal Wolbachia would introduce a toxin (mod function) in sperms which would, after fertilization, induce embryonic death unless an antidote produced by maternal Wolbachia in the egg counteracts its effect (resc function). A to date unique diversity of CI phenotypes has been described in the mosquito species Culex pipiens. This diversity is based solely on the diversity of Wolbachia strains hosted by C. pipiens. In this PhD, we conducted, in C. pipiens, the first study of the cytological mechanism behind embryonic mortality in CI crosses. We showed that paternal chromatin condensation and segregation defects during the first embryonic division were responsible for embryonic death in all CI crosses. These CI defects were the only ones observed indicating that the diversity of CI phenotypes in C. pipiens is not based on a diversity of cellular mechanisms. We then studied the cidA/cidB operon in several wPip strains as the functional involvement of this operon in CI was recently demonstrated in Drosophila. We showed that this operon is amplified and polymorphic in all genomes of sequenced wPip. Investigation of cidA/cidB variants in Wolbachia genomes infecting natural populations of C. pipiens, using more than 250 isofemale lines, enabled us to reveal a robust association between cidB variations and change in mod phenotype. In addition, the presence of an ubiquitous cidA variant supports the role of this gene in the resc function. In C. pipiens, the cidA/cidB operon, through its amplification and diversification, is involved in the CI phenotypes diversity and would operate as a toxin-mod / antidote-resc system: cidB being involved in the mod function and cidA in the resc function

This PhD thesis deals with the problems of fatigue cracking, particularly detected in nuclearstructures, and is a continuation of work already carried out in the laboratory. The objective ofthis study is to provide a numerical prediction tool of the phenomenon of plasticity-inducedcrack closure, during the propagation of a fatigue crack in a CT specimen and in a 304Lstainless steel, taking into account the simultaneous influences of the crack shape and cracklength. This has been first considered through three-dimensional numerical models withABAQUS, through pre-imposed crack fronts geometries. The local stress intensity factors(FIC) evolutions along the crack fronts and over the whole propagation have been compared.Then, a numerical tool, using the ABAQUS code and the programming language PYTHONhas been developed in order to automatically predict the crack shape evolution, depending ondifferent input data (geometry, loads, boundary conditions, contact definition duringpropagation, mesh), starting from a 0.1mm straight notch. The local effective evolution of theSIF ΔK l eff has been supposed to be the driving force for the whole propagation. Fatiguetargeted tests have been carried out in order to allow a critical comparison with the numericalresults, in terms of final crack front shapes under different imposed loading conditions
