Texto completo da fonteThis work draws up a detailed catalogue of coastal forms in limestone roks linked mainly with corrosion and organogenic constructions. Every forms is slowly described and carefully defined. But description is not enough and this study shows how considerable is the part of the organisms, not only in all the destruction processes but in construction ones to. We take into account the part of microphytes algae (mainly cyanophyta) and of grazing animals : all of these processes constitute the biocorrosion which explains largely numerous forms. Algae and animals often build forms and play a great part in the coastal morphology. These actions of erosion or construction are not separated and reliewe one another. The evolution of the coastal forms and the coast itself is polychronio and polygenic. The importance of the corrosion and of the construction depends directly on supply of water, quantitatively and qualitatively. The supralittoral zone knows an often punctual corrosion (giving rock pools) but organogenic construction doesn't appear of very few. In the mediolittoral zone a very active corrosion spreads out, liable for typical forms as a notch or a platform (trottoir) but also for considerable constructions : the cornice of lithophyllum tortuosum and the console of vermetids are the most frequent forms. It is in this mediolittoral zone that the sequences of corrosional forms and construction forms are clearest : organogenic constructions are generally set up on a corrosional coastal profile. In the infralittoral zone, a kind of equilibrium does exist between erosional and construction processes

Texto completo da fonteThe ocean surface is a permanent location of exchanges between ocean and atmosphere, mostly in breaking area. This requires studies of sea state, defined by the wave field properties and the surface resulting of its breaking. The aim of this study was to understand the pro cesses occurring at the interface in coastal zone, to better understand the parameters that control them, and ta introduce a whitecap model in a wave numerical model. This work is essentially based on results obtained during two experimental campaigns that took place in NIediterranean coastal areas (FETCH and EMMA). The waves analysis conduct to determine a specific relation between non dimensional parameters (significant height and peak frequency) following the classical formalism JONSWAP. Study of wind stress at the interface presents an influence of wind speed and f wave age. Results on waves and wind stress show a reasonable agrement with models found n literature. We show that the whitecap coverage depends on classical meteorological parameters (such as wind speed and friction velocity) but also on oceanic parameters (such M wave ge and dimensionless energy). Friction velocity weil represents variations of breaking in coMtal zone when it is measured and not obtained from wind speed. The whole sea state events are better scale with wave age. Finally, a numerical wave model has been adapt to our experimental site (from precedents results) to represent whitecap coverage in the Toulon-Hyères area. From a spatially and temporally homogeneous wind input, a few experimental events has been modeled

Texto completo da fonteCette thèse avait pour objet les habitats de l’Infralittoral rocheux Méditerranéen qui ont un rôle de nourricerie pour les juvéniles de poissons (Téléostéens). Cette étude visait à mieux comprendre leurs caractéristiques et les conséquences de leurs transformations, notamment d’origine anthropique, dans le but de rassembler des données utiles à la gestion des zones côtières. Au sein de la mosaïque paysagère sous-marine, parmi les faciès de la biocénose des macrophytes photophiles de la roche infralittorale, les forêts de Cystoseires forment un habitat à macrophytes arborescentes qui est menacé. Cette thèse a démontré que ces forêts abritaient des densités plus élevées de juvéniles de poissons (notamment Labridae et Serranidae) que celles observées au sein de faciès alternatifs, en particulier les brousses à Dictyotales et Sphacelariales et les faciès de surpâturage. La haute valeur relative de nourricerie, que ce soit des forêts de Cystoseires (pour trois espèces du genre Symphodus), ou des petits fonds à blocs et galets (pour les espèces du genre Diplodus), a été observée de manière récurrente dans les différents sites littoraux étudiés aussi bien à l’échelle locale (1 km) que régionale (20 à 100 km). Cependant, pour un habitat donné, les densités de juvéniles ont montré une forte variabilité spatiale entre sites. La variabilité spatiale des densités de juvéniles, aussi bien entres sites des forêts à Cystoseires que d’un habitat à l’autre, était notamment associée aux différences de structure tridimensionnelle de l’habitat (hétérogénéité et complexité). Cette structuration fournissait un refuge pour les juvéniles et a en particulier influencé l’efficacité de leurs prédateurs. Ces travaux, sur la base de manipulations expérimentales et d’observations in situ, ont démontré que les transformations des habitats, telles que la fragmentation des forêts ou la diminution de la densité de leur couverture, réduisaient drastiquement leurs valeurs de nourricerie pour les poissons côtiers. Ces résultats suggèrent que la productivité en poissons virtuellement perdue, dans les zones où les forêts ont déjà totalement disparu, est considérable. Par ailleurs, ces habitats essentiels se sont avérés rares et in-équitablement distribués le long des côtes : dans le cas des Diplodus spp. , moins de 10% des côtes rocheuses étudiées présentaient des habitats nourriceries. Enfin, ce travail a mis en évidence que la planification actuelle des mesures de gestion des zones côtières méditerranéennes ne prenait généralement pas en compte la distribution spatiale des habitats nourriceries, ni leur connectivité avec les autres habitats essentiels à chaque étape clef du cycle de vie des poissons. Un schéma conceptuel, visant à adopter une telle « approche paysage » de la gestion, est proposé : il vise à promouvoir une focalisation optimale des efforts de conservation et à garantir ainsi le renouvellement des peuplements de poissons côtiers

Texto completo da fonteThe French government has committed itself to an ambitious target of boosting the offshore wind power capacity to reach 6 GW by 2020. Wind turbines onshore as well as offshore are highly contested on visual grounds. Affected stakeholders, ranging from business and property owners, fishermen and elected municipal planners, fear significant negative economic impacts on their ‘business' or their ‘property'. In the French Mediterranean region of the Languedoc Roussillon, the expectation is that the tourist industry will be chagrined in the presence of an offshore wind farm – giving a windy and cemented image of the region. Since talks began about 10 years ago, on the potential for ‘harvesting' the winds of the Mediterranean Sea, many postulates have been made with regard to the impact on coastal tourism. In particular, resistance mounted when plans to include the Languedoc Roussillon in the 2011 tender for the construction of 2 GW wind power capacity were materialising. In this light, it was considered of pertinence to investigate how offshore wind farms, installed at realistic distances from the coast (5, 8 or 12 km), would affect coastal tourism. Additionally, it was considered of interest to help define strategies that coastal community resort may adopt to boost visiting numbers or profit margins with or without wind farms. To answer these questions a full-scale choice experiment valuation survey with over 350 tourists was undertaken in the summer of 2010 on Languedoc beaches.Our survey results show (in chapter 3) that average visual disamenity costs tends to zero, when an offshore wind farm is installed somewhere between 8 and 12 km from the shore. We also find that there is considerable demand for “sustainable” coastal community resorts that favours local produce, bicycling, public transport, energy and water saving devices. Thus, our estimates show that a wind farm installed 8 km from the shore could be ‘compensated for' through the simultaneous ‘greening' of the coastal community resort. If in addition a wind farm is associated with artificial reefs and recreational user access, our results point to an actual rise in tourist related revenues when the wind farm is located min. 5 km from the coast. The policy recommendation is thus two fold: Everything else equals, a wind farm located 12 km offshore will have no negative incidence on tourism. With simultaneous application of a coherent environmental policy and wind farm associated recreational activities, wind farm siting can be conceived from 5 km and outwards.In a latter stage (chapter 5) we explicit account for the well-established fact that humans' over-estimate losses compared with equal-sized gains, in our econometric estimations. By incorporating so-called gain-loss asymmetry in the utility function, we observe that the WTP to remove wind farms had they already been installed is half the compensation required to accept their presence during a vacation. The disamenity costs associated with wind farm installation are thus of a significantly smaller magnitude had the wind farms already been installed. On the other hand, the welfare benefits associated with eco-efficiency and wind farm associated recreational activities are larger had they already been invigorated. The verdict is that asymmetry should be accounted for, or at least recognised in stated preference valuation studies that simultaneously use utility increasing and utility decreasing attributes

Texto completo da fonteOne of the main goals in ecology is to understand the effects of climate change on biodiversity and ecosystem functioning. In marine environments the overexploitation of resources by human activities is another forcing factor on species assemblages. This PhD thesis suggested, within a multicomponentsbiodiversity approach, to project expected changes in the structure of Mediterranean coastal fish assemblages under climate change but also under different fishing pressures. The originality of this work is to consider the dynamics of size structure, diversity of species, but also lineages (phylogenetic diversity), functional traits (functional diversity) and interactions (diversity of trophic links) in fish assemblages at different scales within the Mediterranean basin, the latter three components being largely ignored in climate change projections whereas they are essential for maintaining the viability of ecosystems and associated services beyond the simple number of species. We therefore projected future geographic ranges of Mediterranean coastal fish through theimplementation of a new climate model (NEMOMED8) and based on bioclimatic envelopes models. Projected range shifts of Mediterranean coastal fish show that for the end of the century (i) 54 species would lose their climatic niche, (ii) species richness may decline on 70.4% of the continental shelf, particularly in the Western Mediterranean basin and in the Aegean Sea, and (iii) the average maximum size of fish assemblages would increase on 74.8% of the continental shelf. The small species, not targeted by fishing activities, would be the species most threatened by climate change, while larger species are most vulnerable to fishing effort.Our projections at the whole Mediterranean scale show a decrease of 13.6% for the phylogenetic diversity (PD) of coastal fish and 12.6% for their functional diversity (FD) by the end of this century and suggest a significant erosion of some lineages like the gobidae family. While erosion of PD and FD is partly due to the loss of species richness (fewer species implies less lineage and functions) we obseved, especially in the western basin, that the fish assemblages would loss more phylogenetic and functional diversity than expected simply due to the erosion of species richness. These two components, were largely ignored in conservation of marine species assemblages and appear to be strongly impacted by global change.To understand the effects of climate change on food web structure we developed a new methodology based on the robust relationship between the size of preys and predators. We were able to highlight potential changes in food webs of fish assemblages under climate change for the Mediterranean continental shelf. We found that a significant portion of the Mediterranean continental shelf would face a reduction in the number of trophic links, vulnerability (number of predators per prey) and generality (number of preys per predator) of species on average, while connectance and trophic level within fish assemblages would increase by the end of the XXIth century.Beyond changes in species richness, the Mediterranean coastal fish assemblages may be modified, in the functions that they play in ecosystem, in the amount evolutionary history they support, as well as in their interactions structuring food webs. This PhD thesis paves the way towards the biogeography of ecosystem functioning using parsimonious and hybrid models to integrate different components of biodiversity, physical oceanography, and the level of exploitation of ressouces to infer the futur of marine systems cfunctioning facing multiple pressures that are already there
