Texto completoThis work aimed to study effects of uranium on energy budget and population dynamicsin Daphnia magna a representative microcrustacean of freshwater ecosystems. An experimentalstudy of uranium toxicity on physiology (nutrition, respiration) and life history (survival, growthand reproduction) of D. magna was carried out, based on exposures over one, two or threesuccessive generations (F0, F1 and F2) started with neonates from 1st or 5th brood, at 0, 10, 25and 75 μgU.L-1. Results showed that toxic effects increased across generations (partially due todaphnid exposure during embryogenesis) and that individuals from 1st brood were moresensitive than individuals from 5th brood. Significant reductions in assimilation rates, measuredusing a radiotracing method with 14C-labelled food, allowed us to identify an effect onassimilation as the mode of action for uranium, in agreement with important damages in theintegrity of intestinal epithelium observed by optic microscopy. Integrating results in a dynamicenergy budget model (DEBtox) yielded estimated no effect concentrations (NEC) of 9.37, 8.21and 2.31 μgU.L-1 above which organism functions were altered in generations F0, F1 and F2,respectively. Combining DEBtox with matrix models allowed us to extrapolate consequences onasymptotic population growth rate (λ), a relevant endpoint in an ecological context. Simulationspredicted an increase in uranium impact across generations with reduction of λ in F0 andpopulation extinctions at 51-59 μgU.L-1 in F1 and 39-41 μgU.L-1 in F2. Simulations emphasizedthe importance of considering the most sensitive individuals while determining populationresponse

Texto completoSince the early 1960s, the growth of yellowfin has been enjoyed a particular attention both in the research field and for fisheries management. In the Indian Ocean, the management of yellowfin stock, under the jurisdiction of the Indian Ocean Tuna Commission (IOTC), suffers from much uncertainty associated with the growth curve currently considered. In particular, there remain gaps in our knowledge of basic biological and ecological processes regulating growth. Their knowledge is however vital for understanding the stocks productivity and their resilience abilities to fishing pressure and oceanographic changes underway.Through modelling, this study aims to improve current knowledge on the growth of yellowfin population of the Indian Ocean and thus strengthen the scientific advice on the stock status. Whilst most studies on yellowfin growth only rely on one data source, we implemented a hierarchical Bayesian model that exploits various information sources on growth, i.e. direct age estimates obtained through otolith readings, analyzes of modal progressions and individual growth rates derived from mark-recapture experiments, and takes explicitely into account the expert knowledge and the errors associated with each dataset and the growth modelling process. In particular, the growth model was coupled with an ageing error model from repeated otolith readings which significantly improves the age estimates as well as the resulting growth estimates and allows a better assessment of the estimates reliability. The growth curves obtained constitute a major improvement of the growth pattern currently used in the yellowfin stock assessment. They demonstrates that yellowfin exhibits a two-stanzas growth, characterized by a sharp acceleration at the end of juvenile stage. However, they do not provide information on the biological and ecological mechanisms that lie behind the growth acceleration.For a better understanding of factors involved in the acceleration of growth, we implemented a bioenergetic model relying on the principles of Dynamic Energy Budget theory (DEB). Two major assumptions were investigated : (i) a low food availability during juvenile stage in relation with high intra and inter-specific competition and (ii) changes in food diet characterized by the consumption of more energetic prey in older yellowfin. It appears that these two assumption may partially explain the growth acceleration

Texto completoThis PhD work explored how depleted uranium alters DNA and affects life history traits (survival, growth and reproduction) of an aquatic invertebrate, Daphnia magna. An experimental study is performed to evaluate DNA accumulation and transmission during an uranium exposure over two successive generations (F0 and F1). Different exposures scenarios are achieved to test the specific sensitivity of several life stages to uranium. Genotoxic effects are estimated using random amplified DNA technique combined with PCR. In continuous and post-hatching exposure scenarios, results highlighted an accumulation and a transmission of DNA damage across generations with an increase in effect severity. DNA alterations are reported at hatching of F1 at 2 µg L-1. Effects on growth and reproduction are stronger when the embryo stage is exposed and remain visible at 9.9 µg L-1 despite a return in a clean medium at hatching. Results suggest that DNA damage could be used as early indicators of future effects on life history traits. A mechanistic analysis of experimental results is conducted using a DEBtox model to better understand the causes of the increase in effect severity across generations. A model with two stress factors (one correlated to external concentration and another correlated to a damage level) is developed. Results of fits suggest the involvement of one second mode of action (increase in costs for growth and maturation) to explain immediate effects of uranium on nutrition and consequences of cumulated damage across generations

Texto completoThe life cycle of the internal tide and its loss of coherence due to its interactions with currents are studied over the North Atlantic basin using a high-resolution simulation of a realistic ocean. A vertical mode decomposition is used to obtain the energy budget of the different scales of the internal tide. Topographic scattering is dominant at the basin scale and around topographic features, while interactions between the internal tide and the low-frequency circulation are significant in the Gulf Stream, its North Atlantic extension and in the northern part of the basin. Finally, a coherent/incoherent decomposition is used. The causes of the internal tide loss of coherence on scales of one to three months are the advection of the internal tide by the slowly varying current and the horizontal shear of the latter. Most of this loss of coherence occurs without any change of scale for the internal tide

Texto completoAddressing the global challenge of environmental sustainability in the building sector, this thesis focuses on advancing methodologies for greenhouse gas (GHG) budget compliance in building post-occupancy stages. It emphasizes the need for dynamic assessment in the decision-making processes to enhance the process of ensuring carbon budget compliance.The research employs a multifaceted approach, beginning with an exploration of current methodologies for building GHG budget compliance. This includes a thorough examination of carbon budgets, Life Cycle Assessment (LCA), and Dynamic Life Cycle Assessment (DLCA). The study then progresses to refine the DLCA methodology, focusing on reducing simulation times and optimizing the number of dynamic parameters. Techniques such as linear interpolation, surrogate modelling, feature selection, sensitivity and uncertainty analysis are tested for these tasks. Then, through a case-study, the importance of decarbonization of the industrial, waste and energy sectors in dynamic GWP calculations are highlighted.Furthermore, the enhanced DLCA methodology is applied in the context of retrofit decision-making, showcasing its utility in adapting to carbon budget deviations throughout a building’s life cycle. This application is exemplified through the same case-study of a single-family home in the Paris region, demonstrating the methodology’s effectiveness in guiding retrofit decisions in alignment with carbon budgets and broader environmental objectives. However, the findings also reveal the scenario-dependent nature of these decisions, indicating that budget-compliant buildings can exhibit diverse characteristics based on different DLCA assumptions.Overall, this research emphasizes the critical role of integrating dynamic parameters in retrofit decision-making processes. Simultaneously, it also challenges and assesses the applicability of these methods within the framework of carbon budget compliance, providing a detailed evaluation of their impact on sustainable building practices

Texto completoIn the context of climate change, it is essential to estimate precisely and be able to monitor over time the energy balance of the Earth at the top of the atmosphere and at the surface. In terms of measurement, obtaining a correct estimate of the radiative balance requires a precise determination of the shortwave (solar) and longwave (infrared) radiative fluxes. The objective of this thesis is to assess the solar radiative fluxes obtained from the French radiometer POLDER on board the PARASOL microsatellite supported by CNES. A first part of the thesis presents a comparison between the operational products computed from POLDER observations with the reference fluxes obtained through the broadband radiometers CERES on the NASA space platforms Aqua and Terra. The comparisons are made over two periods: first a period with coincident measurements (2005-2009), then a second period which corresponds to the drift of the PARASOL satellite (2010-2013). We show that this drift had an impact on the observations, with strong repercussions on the calculated fluxes. Over the period of coincidence of the measurements, POLDER fluxes are very close to the fluxes from CERES for two of the products studied (CERES SSF1deg and CERES SYN1deg) with relative differences under 2% until December 2009. After 2010, the relative difference increases with the drift. A land/ocean compensation effect is also revealed. The results obtained through these comparisons led us to study in detail the component of the algorithm used to obtain the monthly means of POLDER shortwave fluxes. This part of the algorithm is the diurnal extrapolation, used to estimate a value of albedo at all hours of the day from a single observation using models that are scene-dependent. The models used for the operational products were built using four months of POLDER-1 observations (1996-1997). We decided to take advantage of the data obtained throughout the entire PARASOL mission to improve these models. The shortwave fluxes obtained with the new models show less dependence on the drift over oceans but a drift is still present over lands. These results led to several propositions that could improve POLDER's shortwave fluxes, mainly by increasing the number of POLDER models. This work, based on measurements from POLDER-3, which was shut down in December 2013, but whose data is available, will be largely reusable for the future multispectral, multi-angular and polarized radiometer 3MI, developed by ESA and EUMETSAT and which will fly onboard the EPS-SG mission supported by EUMETSAT from 2024, for approximately 20 years
