1. Evolution of symbiotic lineages and the origin of new traits
Abstract : This thesis focuses on the genomic study of symbionts of two different groups of hymenopterans: bees and ants. Both groups of insects have major ecological impact, and investigating their microbiomes increases our understanding of their health, diversity and evolution. READ MORE

2. Regulation of hematopoiesis in the freshwater crayfish, Pacifastacus leniusculus : role of transglutaminase
Abstract : The freshwater crayfish, Pacifastacus leniusculus, has been used as a model for studying hematopoiesis or blood cell production or hematopoiesis and immunity. The work of this thesis aims to investigate the impact of factors such as ROS signaling, Ast1, and the PVF/PVR signaling pathway in controlling stem cell behavior during hematopoiesis and specifically the role of the crosslinking enzyme transglutaminase (TGase) in regulation of hematopoiesis.

3. Mitochondrial Iron Metabolism : Study of mitoferrin in Drosophila melanogaster
Abstract : Iron has a dualistic character. On the one hand it is essential for the life of most organisms, on the other hand it is involved in the generation of reactive oxygen species that are implicated in diseases and aging. READ MORE

4. Intraspecific divergence and phenotypic plasticity in behavioural profiles of teleost fish
Abstract : Behavioural differences between and within individuals can greatly affect the outcome of behavioural studies. In addition, behavioural interactions between individuals can compromise the health and welfare of captive fish. READ MORE

5. The role of leptin in zebrafish (Danio rerio) : Novel insights into appetite regulation and reproduction
Abstract : The hormone leptin is a peripheral metabolic signal and an important regulator of energy balance. In mammals, leptin acts on the appetite centers in the hypothalamus, causing anorexigenic functions by inhibiting food intake. It is also considered as a link between the nutritional status and the endocrine reproductive axis. READ MORE
