Full textThroughout their life, wild species face periods of food-deprivation that induce energy tradeoffs between survival, growth and reproduction. These fasting periods occur either when food availability is lacking due to adverse climatic conditions or because individuals are engaged in biological processes that prevent food access. This later reason is particularly well illustrated in the king penguin (Aptenodytes patagonicus), a sea bird that has to moult and reproduce on shore whereas he feed exclusively at sea. Moreover king penguin chicks exhibit exceptional survival capacities during their first year of life when they experience a long period of fast in winter. Thus, this species that lives in sub-Antarctic latitudes, is exposed to environmental and physiological energy constraints during food shortage periods. Since king penguins are endotherms, they need to maintain their body temperature at high level despite variations of ambient temperature. Thus thermoregulation is one of the most expensive process and skeletal muscles account for the greater part of heat production in birds. Several studies showed that despite long term cold exposure, energy expenditure of fasting birds decreases allowing energy savings and especially protein sparing. Since skeletal muscles have high implications in energy expenditure and heat production the question of their implication in energy saving mechanisms arises. During my PhD project I studied skeletal muscle metabolism through mitochondrial efficiency. These sub-cellular organelles are the last effectors of energy transduction from nutrient into ATP, an usable energy for cells. Our hypothesis is based on the flexibility of mitochondrial efficiency as a regulator of energy sparing mechanisms which would explain long term resistance to starvation. My studies were conducted in a wild species, the king penguin chicks, that are naturally acclimated to cold environment and experienced long term fasting stage. To further investigate mitochondrial plasticity in response to energy constraints, I developed several experimental procedures in controlled conditions on a laboratory model (Muscovy ducklings)

Full textThe intestinal microbiota is an important element for the host; it is particularly involved in immunological or physiological level. Knowledge of the composition of the microbiota is the first step in understanding the phenomena associated with it. The work of this PhD was organized according to several objectives. The first step was to realize a molecular inventory of the microbiota composition of the two parental genetic types: the Pekin duck (Anas Platyrhynchos), the Muscovy duck (Cairina moschata) and their hybrid, the mule duck. We have observed different compositions depending on the genetic type although with a predominance of two phyla: the Firmicutes and Bacteroidetes for all ducks species. Different conditions encountered in the environment are likely to create an imbalance in the composition of the microbiota. One is a change in diet; therefore the second step was to see the impact of overfeeding on bacterial communities. Overfeeding causes many changes in the bacterial microbiota and increase two classes: Bacilli and Clostridia according to the genetic type. The effect of overfeeding has been shown principally on the ileal microbiota while genetics and overfeeding both affected weekly cecal microbiota. We then studied the impact of adding a probiotic strain (Lactobacillus sakei) on the microbiota of mule ducks during the overfeeding period. We could see here a significant effect of this addition only in the ileum with a sharp increase in lactobacilli. Finally, due to high levels of contamination found in the southwest of France and its toxic effects on metabolism shown in various studies, the last work was to see the effect of cadmium on the microbiota of Pekin and Muscovy ducks. We observed changes in the microbial community when adding cadmium and see the accumulation of it in the kidneys during overfeeding. Combined effects between cadmium and the feeding period as well as the genetic type were highlighted. Finally

Full textCold-exposed young birds maintain their homeothermy by stimulating mitochondrial oxidations in skeletal muscle. Prolonged cold exposure enhances muscle thermogenic capacities through mitochondrial bioenergetics plasticity which control still remains hypothetical. In mammals, fusion proteins (mitofusins (Mfns) and OPA1 (Optic Atrophy 1)) contribute to the permanent and dynamic changes in mitochondrial networks in multiple cell types. The aim of our work was to characterize the expression of avian homologues of mammalian fusion proteins and to study the variations of their expression during the establishment of bioenergetics processes in growing birds, during an acute or a prolonged cold exposure and finally during nutritional or endocrine challenges. Methodologically, an integrative approach has been used from whole animal (indirect calorimetry) to protein (western-blot) or gene (RT-PCR) expression through measurements of the bioenergetics functionality of permeabilized muscle fibers and isolated mitochondria. Two animal models were used, a species naturally adapted to Antarctica harsh conditions, the Adélie penguin (Pygoscelis adeliae), and a laboratory model, the Muscovy duck (Cairina moschata).Our results allowed us to characterize, in birds, the expression of immunoreactive fusion proteins (Mfn2, OPA1) which were homologous to those of mammals. The sequencing of a part of the coding sequence of Mfns genes showed a great similitude between avian and mammalian species. In penguins, the relative abundance of these proteins in muscle mitochondria was modified by growth in the cold and was positively correlated with muscle bioenergetics capacities. In ducks, the respiratory activity and the relative abundance of these proteins were also correlated after a 60h fasting period or,though a lesser extent, after a pharmacological alteration of thyroid status. Our results show, for the first time in birds, the expression of proteins homologous to mammalian fusion proteins. The association between the changes in expression of these proteins and the bioenergetics modifications in skeletal muscle indicates that these proteins could contribute to thebioenergetics plasticity observed in growing chicks. These results suggest that potential modifications of the muscle mitochondrial network organization could play a role in the adaptive responses of organisms to the environmental constraints
