Full textThe spatial patterning of organisms and the resultant consequences are central questions within the science ofboth pure and applied ecology. Spatial heterogeneity is indeed of primary interest within the field of ecological restoration for both the conception and evaluation of projects. The work that has been developed during this PhD project encompasses a study of spatial patterning set against a background of ecological restoration. The study was carried out with a model study system, within an anthropogenic system: the banks of channels deriving the river Rhône. The links between plant spatial patterns and their biological traits have been analysed in this model system with an underlying aim of understanding their role in both community structuring and functioning within a hierarchical system. This approach is based upon the analysis of spatial patterns &om the plant neighbourhood through to the landscape scale. Ln doing so, this needed to combine concepts and methodological techniques derived &om remote sensing, spatial statistics and functional ecology. The results provided an explanation of the development of spatial pattern of vegetation, at various scales, in interpreting the role ofbiological traits related to endogenous processes and/or plant responses to exogenous factors. A synthesis of the results from this study led to the development of a conceptual model that integrates the role of spatial vegetation pattern, plant traits and their interrelationships in the functioning of plant communities. The results from this work also offer practical management perspectives for the evaluation of restoration projects

Full textOne of the consequences of the global warming is the modification of the freshwater flux get by the ocean. The thermohaline circulation is able to produce some low frequency variability. We are going to study the impact of the freshwater flux on the thermohaline circulation and mainly on the decadal to millennial variability. In the ocean two paradigms coexist for the explanation of the observed variability: it can be endogenous or exogenous. During the study of endogenous variability in a 2D latitude-depth model, the growth mechanism and the oscillation one of a centennial mode are characterized. This mode, corresponding to a salinity anomaly advected around the circulation, is feed by the positive salinity feedback on the advection. A millennial oscillation cycle which appears through an infinite-period bifurcation is characterized. Thus, we point out that the centennial oscillation is a precursor of millennial oscillation. During the study of the exogenous variability, the optimal perturbations of the sea surface salinity influencing the ocean circulation are performed in three models of the thermohaline circulation: a latitude-depth model, a planetary-geostrophic model and a primitive equation in global realistic configuration. Moreover, by this study et the optimal perturbations, we have fixed modification bound of the ocean circulation at 0. 75 Sv and at 0. 03 PW

Full textWe studied two important photoprotection mechanisms, endogenous zinc dependant photoprotection and exogenous photoprotection ensured by sunscreens. Firstly our work demonstrates the protective role of zinc treatment against oxidative stress in HeLa cells. We showed that metallothioneins were strongly expressed in zinc treated cells. Then a great protection against DNA oxidative damages and cell death was observed. The induction of metallothioneins, i. E. Small cystein rich proteins, seems to represent the main way for zinc to afford protection against oxidative cellular damages. Secondly we demonstrated the protective role of zinc on keratinocytes exposed to solar light. The genoprotection afforded by zinc treatment was inductible and correlated to the time of zinc treatment. The nuclear redistribution of MTs indicates the important role of these proteins in the protection of the genome after a solar irradiation. We showed that only Zn-metallothioneins could afford genoprotection. After irradiation, the intracellular amount of MTs decreased, probably due to the protein oxidation by irradiation induced ROS. As a consequence MTs released zinc atoms which could stimulate the activity of nuclear zinc proteins such as XPA. Moreover the intracellular MTs degradation could modulate the nuclear redox potential and consequently the Ref-1 protein activity. Our results on XPA and Ref-1 show that zinc treatment modulates the expression of these two DNA repair enzymes. These results underline the interrelation between zinc, MTs, and DNA repair systems in maintaining genomic integrity. Our study concerning exogenous photoprotection induced by sunscreens demonstrates the importance of new biomarkers to assess the real photoprotective profile of a sunscreen in addition to SPF determination. These important biomarkers (CPF, GPF, APF, EPF), evaluated in vitro, could be considered as important parameters to evaluate the long term photoprotective capacity of sunscreens as they take in account both UVB and UVA deleterious effects

Full textThe effects of tissue-type plasminogen activator (tPA) in the brain parenchyma are pleiotropic. In an ischaemic context, the balance between beneficial and deleterious effects of tPA modulates neuronal death. My thesis work consisted, (i) in the study of the influence of alcohol exposure on the thrombolysis benefit/risk ratio, (ii) to study the influence of endogenous tPA on ischemic neuronal death in the hippocampus. In the study concerning the impact of alcohol consumption on the thrombolysis benefit/risk ratio, we show a loss of beneficial effect of thrombolysis on ischaemic damage. We propose that this loss of efficiency depends on the brain-liver axis in terms of tPA clearance and bioavailability, that might lead to aggravate brain damages, possibly due to neurotoxic effects of tPA. In our opinion, challenges like alcohol consumption, even moderate, which can induce subtle liver dysfunction, may profoundly impact the outcome of thrombolysed-stroke patients. We also demonstrate that tPA may have neuroprotective effects, especially when produced and released by stressed neurons, suggesting differential properties of exogenous and endogenous tPA. Based on our present observations and current literature in the field, we can postulate that strategies contributing to promote either endogenous production of tPA or its signalling, including EGFR pathway, may have beneficial effects following brain injury such as stroke. To summarize, my thesis results confirm and bring new element defining tPA as a pleiotropic protein with differentials effects depending on its origin and cellular processes in which it is involved
