Full textProductivities, decomposition rates and nutrient turnovers are low in polygon fens of Bylot Island. The Greater snow geese population could modify these parameters since goose faeces contain nutrients that are easily uptaken. However, it is important to consider the moss carpet. This study showed that mosses play an important role on the polygon fen dynamic by sequestrating the nutrients added by goose faeces. Grazed plants were able to uptake nutrients only when the mosses are saturated and consequently, when nutrients reach their roots. The decomposition rates and the turnover of nutrients were not affected by nutrient additions. In addition, in the short-term, it seems that fertilizing effect of geese was visible only on moss growth. As a secondary result, this study showed that innate marker method is the most appropriate to estimate moss primary production in arctic wetlands.

Full textGround vibration is an increasingly important environmental problem. This study investigates multiple aspects of ground vibration. Local site conditions and the related amplification of seismic waves represent a widely studied topic in seismology and earthquake engineering. While most of the studies are dedicated to engineering seismology and earthquake engineering, similar approaches for soil classification and site amplification have not been yet fully established in the field of urban vibrations.First an improvement strategy for absorbing layer method was developed in order to enhance precision of the FEM models. The design of simple absorbing layers in FEM through the nullification of the real part of reflected waves in the complex number domain proved to be efficient when coupled with the stiffness reduction of the absorbing layer. Excessive reduction of the stiffness along with the excessive increase of the stiffness factor in the attenuation matrix enabled a large reduction in the size of the absorbing layer and therefore the design of an inexpensive absorbing layer.Afterwards an important part of the work was dedicated to the derivation of a new set of parameters of the velocity-gradient type that controls the vibration transfer through multilayered soil. The absence of a well-structured comprehensive approach for prediction and site classification for vibration problems leaves the problem broad and complicated. Different sites with different mechanical and geometrical properties were examined using FEM and their surface response was studied. Sites responses were formulated in simple time domain and spectral approaches. The newly derived proxies along with the spectral laws serve as a classification mean for multilayered soils in the vibration problem and may even be used for design purposes.An artificial intelligence tool for predicting soil response using the previously derived proxies coupled with the geometrical properties of the surface layer was later developed. The neural networks tool was used to analyze the parametric effects of the velocity-gradient proxies versus that of the surface layer’s depth. Important conclusions were derived from the analysis regarding the mechanical and geometrical properties of multiple layers and their varying effects with distance from the source.Finally multiple sources recordings were studied through comparing them with the spectral responses of different sites defined in the previous sections. The rate of matching between the spectral content of a particular source and a given site serves as a mean to assess the vibration hazard caused by this source to the corresponding site. The vibration hazard assessment leads to a classification link between sources in one hand and sites characterized by velocity-gradient proxies on the other hand

Full textPharmaceutical substances belong to the group of emerging contaminants due to their recent interest in environmental studies in comparison with pollutants who have been studied for a longer time like pesticides. They correspond to the active ingredient of drugs and by this mean are responsible for their pharmacological properties. Consequently they are biologically active molecules that can act on living organisms present in impacted ecosystems. The origin of pharmaceuticals in the environment is variable but the main sources are related to their use in human and veterinary medicine. Once consumed, pharmaceutical substances are excreted in urine or feces and are found in wastewater (human consumption) or animal manure (veterinary consumption). In the first case, they can be discharged directly in the environment, or indirectly, with treated wastewater or sludge from sewage treatment plants (SWTP). In the second case, they directly reach the environment when animals are bred on grassland or indirectly when livestock wastes are spread on agricultural soils as fertilizer. This PhD work has been focused on the study of the origin and fate of pharmaceutical substances in these 2 cases. Thus according to consumption data, occurrence in the environment reported in previous studies, toxicity and ecotoxicity data, originality and availability of reference standard compounds, 32 then 78 molecules belonging to 5 different therapeutic classes (antibiotics, antineoplastics, beta-blockers, anti-HIV, phosphodiesterase type 5 inhibitors (PDE 5 inhibitors)) were studied in 2 continuums : i) hospital wastewater effluents – raw and treated wastewater – surface water, and ii) raw and treated wastewater – surface water – ground water. Based on the same selection criteria, the fate of 7 antibiotics was studied in pig manure in simple manure storage facilities (storage tank), in aerobic manure treatment facilities (treatment system like in small SWTP) and in mesocosms under controlled conditions. In order to achieve all these studies, analytical protocols implementing an extraction step by SPE (Solid Phase Extraction) or an ASE extraction (Accelerated Solvent Extraction) followed by a SPE purification and an analytical step by LC / MS / MS (liquid chromatography tandem mass spectrometry) have been developed. These protocols, by filling out quality criteria such as limits of detection and quantification compatible with environmental analysis (ng/l to dozen of ng/l), good linearity, precision, accuracy and performance, were used to analyze the dissolved phase of water samples and dissolved and solid phases of pig manure samples. The water samples analysis shows : i) beta-blockers, anti-HIV and antibiotic belonging to the families of macrolides, fluoroquinolones and sulfonamides are the most representative molecules of the environmental contamination from the classes studied; ii) SWTP releases are a major source of aquatic systems’ contamination; iii) wastewaters are more contaminated in winter than in summer; and iv) surface water are more contaminated in summer than in winter. The pig manure samples analysis shows : i) the levels of contamination of manure by antibiotics are high, from a few µg/l to mg/l; ii) the manure level of contamination is not related to the physiological stage of pigs; iii) the interest to store manure before spreading in order to reduce the antibiotics contamination is not highlighted; iv) oxytetracycline, tetracycline, tylosin and marbofloxacin are mainly present in the solid phase whereas sulfadiazine, lincomycin and monensin are mainly present in the liquid phase of manure; v) the separation of solid and liquid phases reduce manure contamination in aerobic treatment facilities; and vi) antibiotics degradation is mainly aerobic.Key words:

Full textPorifera and Ctenophora are probably the two most ancient animal lineages. Their study therefore allows to trace back the early history of metazoans and to address the origin of the distinction between somatic and germ lines. Indeed, in sponges this distinction does not exist: archeocytes and choanocytes can give rise to both somatic cells and gametes.After establishing the list of genes considered to be involved in gametogenesis in metazoans, I searched for these candidate genes (by local blast) in the transcriptomes of two sponge species (Oscarella lobularis and Oopsacas minuta). I thereby managed to characterize their sequences (phylogenetic and protein domain analyzes) and to trace their evolution through comparative analyzes including all main animal phyla. Finally, the in situ monitoring of O. lobularis enabled me to refine its life cycle and access all key developmental stages in order to study the expression of candidate genes in order to test their possible involvement in gametogenesis in this species.I have shown that 18 GMP (Germline Multipotency Program) genes are present ancestrally in animals. Among them, at least 11 are expressed not only during gametogenesis but also during embryogenesis, asexual reproduction and regeneration. Finally, in situ monitoring showed the influence of temperature variations and organic matter availability on gametogenesis.My work suggests, firstly that the specification of germ cells is controlled by common genetic mechanisms across metazoans, and secondly that these ancestral genes might be involved in pluripotency. These results reinforce the hypothesis suggesting a common origin of the germline and somatic stem cells
