Testo completoThree chronologies, topographies and morals emerge from this "geohistory" (Fernand Braudel) of the french mountains between 1940 and 1944. First, Marshall Petain's mountains from 1940 to 1942, where the local way of life or "temperament" (André Siegfried) can be found in the traditional values. "Petinophile" patriotism, different from "vichysme" prevails, particulary in the eastern border mountains, with anti-german and anti-italian feelings symbolised by the Marshall Petain Peak (3507 m. ) and the novel "Premier de cordée" by patriot writer Roger Frison-Roche. The time of withdrawal and "shield" begins after the defeat, with a new feeding and attractive mountain. Then, from 1941 to 1943, mountains become "swiss", like a proverb. They openly reject the policy of collaboration with the Germans and stand in favour of a pro-allied neutrality. Black or grey markets flourish mainly in luxury tourist villages, thus giving rise to anti-tourist and anti-jew feelings - not to be confounded with anti-semitism. On the other hand, protestant mountain appears morally and spiritually with the welcome of jewish population. At last, and from the days of the STO law (16/02/1943), mountains become "balkanic" (Winston Churchill) with the heroic time of "maquis". In 1943, the mountains shelter 100,000 young "refractaires" supported by the local farmers whom they eventually help. By the end of 1943, warlike passions prevail : mountains become terrifying with early "maquis" of Haute-Savoie and Correze, up the capital's maquis, Grenoble and the famous meeting of 1944 : Glières, Mont Mouchet and Vercors. Local villagers fear the false maquis and german reprisals. To conclude : the "beautiful" refuge-mountain for Jews and "refractaires" and the "sublime" maquis-mountain of maquis are to be distinguished the one from the other ; marginal mountain can be seen in the center of the history of occupied France

Testo completoThe tradition agriculture of french mountains have a long time, been known for the large number of cheese productions specific of this damp surrondings. Today, this legacy is symbolised by the numerus aoc, which guarantee the gunuinenees of this products. This districts in altitude are nevertheless marked by a true variety deriving from the intensity of the cheese tradition, andthe management of this inheritence by local interveniers. Generaly speeking, one might contrast the cheese traces of the jura and savoie, dedicated to local and high quality products : with thowses of the massif central, more diversified and more widely industrialised, with cheeses which to some extent tend to a certain vulgarisation

Thesis, Aix-Marseille, 2018. http://www.theses.fr/2018AIXM0777/document.
Testo completoThe present thesis deals with a general problem for many developing countries and in particular for Latin America, related to the fight for the survival of the communities of workers who work in informal economies but subject to market rules. the absence of public policies and territorial planning processes that materialize in their favor and lead to a strong inter-institutional dislocation in the territory. The problem is more complex because of the inherent fragility or intrinsic or endogenous vulnerability of the populations themselves, because of the lack of a minimum vital to lead a dignified life, in terms of well-being and quality of life .The research addresses a specific case in a Colombian Andean watershed (the Chinchiná River in the Central Cordillera Range), where a social group extracts river materials (sands, gravels and rocks) for the industry of construction. Although this analysis focuses on the vulnerability factors and the resilience of the social group to global changes and, more particularly, on the dynamics of governance; The thesis focuses on the study of the entire economic production system, as a unit of analysis. The overall objective is to analyze the vulnerability factors and the socio-environmental resilience capacity of poor communities who extract dredged material in the Chinchiná River basin to contribute to the consolidation of planning and sustainable development processes registered in territorial public policies

Testo completoThe alpine meadows dominated by the sedge Carex curvula are among the most emblematic plant communities of the alpine vegetation of the European mountains. This work aims at exploring the spatial patterns of genetic diversity within C. Curvula and the spatial patterns of species diversity in the meadows where C. Curvula is dominant. This comparative study has been conducted throughout the whole distribution area of this type of alpine ecosystem in Europe. First, this work examines the floristic variability of the C. Curvula communities and tries to identify the most important drivers for the species distribution within the European alpine belt. The results show an important variation in the spatial distribution of species diversity among mountain ranges. The floristic boundaries match only partly the geographical limits. The current species distribution in the alpine belt of the high mountains in Europe has to be related primarily to large-scale, historical drivers and only secondarily to local-scale, ecological determinants. Then, we study the phylogeographical patterns of C. Curvula using nuclear and chloroplastic molecular markers. The spatial distribution of genetic diversity highlights a contrasting impact of Quaternary glaciations in the Eastern and Western part of Europe. Based on genetic data, we infer a large East-West recolonization wave in the Alps and local, upward migration events in the Carpathians after ice retreat. We hypothesize recent long-distance dispersal from a secondary glacial refugium located in the South-Western Alps to explain genetic diversity observed within Pyrenean populations. Finally, we explore the relationships between genetic and floristic diversity. Our result support a lack of positive correlations between the two levels of diversity, contrary to what is suggested by several theoretical works. We explain this situation by a contrasting history of genes and species in response to the spatial range dynamics driven by temperature fluctuations during the Quaternary. To conclude, we call for further multidisciplinary studies (including species distribution modelling) to investigate the biogeography of these alpine meadows in a context of global change

Testo completoDans un premier temps, ce travail examine la variabilité floristique des pelouses dominées par C. curvula et tente d'identifier les forces qui ont joué le rôle le plus important dans la structuration des espèces de l'étage alpin acidiphile européen. Les résultats des analyses montrent qu'il existe une variabilité importante pour la distribution de la diversité interspécifique et seulement une correspondance partielle entre la position des barrières biogéographiques de l'étage alpin et les grandes distances géographiques qui séparent les massifs montagnards. Il ressort nettement que les forces qui ont joué le rôle le plus important dans la structuration floristique de l'étage alpin acidiphile européen sont de nature historique et dans une moindre mesure de nature écologique.
Ensuite, nous explorons la distribution de la diversité génétique dans les populations de C. curvula dans un contexte phylogéographique. L'impact des glaciations quaternaires correspond à deux histoires différentes pour les flores alpines dans les montagnes de l'ouest et de l'est du continent européen. Chez C. curvula, les mécanismes de recolonisations postglaciaires auraient impliqué un large vague de migration est-ouest dans les Alpes et une migration verticale beaucoup plus locale dans les Carpates. Les Pyrénées auraient été colonisé plus récemment, à partir d'un refuge secondaire localisé dans les Alpes du Sud-Ouest.
Enfin, dans un troisième temps, nous nous intéressons au problème des relations entre la diversité génétique et floristique, en analysant la diversité locale des espèces dans les pelouses à C. curvula et la diversité génétique de l'espèce dominante. Le manque de corrélation positive entre les deux niveaux de la diversité est expliqué par des réponses différentes des gènes et des espèces aux grands changements climatiques qui sont intervenus au cours du Quaternaire.
Nous concluons sur les perspectives de biogéographie comparative ouvertes par ce travail, en particulier sur l'articulation souhaitée entre les efforts de modélisation de la distribution biologique, la phylogéographie et l'écologie évolutive.

Testo completoIn the rainy Pontic mountains (Northeast of Turkey) people sing and dance at the sound of the kemençe, a tiny three stringed fiddle. Through fieldwork in those mountains, the purpose of this dissertation will be to describe what would be called a “communal use” of music: a musical tradition not understood as art (the creation of artists) but as a common within a certain community. From this observation, the goal will also be to understand the logics of folklorisation and commercialization at work in Turkish music since a century

Testo completoThe reform of the administrative organisation undertaken in France from 1982 on wards permitted mountainous areas to be given a specific legislative status. To respect the continuity of the great decentralisation laws of 1982-1983, the January 9th 1985 law concerning the development and the preservation of the mountain aims at a most praiseworthy objective that is to make self development the solution to the problems encountered by this dispensatory space. A further analysis of the various clauses included in this law as well as a reflexion on the applicability of some measures prompts us to curb the enthusiasm provoked by the vote of this law

Testo completoThis research is positioned within the field of contemporary architecture and landscape as components of the image of the mountain city. Its issues are framed in a qualitative perspective and enquiry fields are analysed using a methodology based on perception by the senses. An analysis of the Alpine context - paradigm of the European mountain in every sense -, aims to provide clues leading to a médiance in a Portuguese mountain urban context: the city of Covilhã, in the Serra da Estrela. The research axis regarding Alpine reality focus on three main aspects: the influence of the Alpine paradigm in the European space, the Alpine architecture as landscape construction since the Modern Movement, and the specificities of the Alpine urban context. The latter concerns the evolution of the relation between city and mountain, and the current issues and trends, observed from different levels. These range from the scale of international relations to the scale of the localised urban fragment. On this smaller scale, the architecture of new interventions, while considering its surrounding landscape, can assume an important role both for the reconstruction of a genius loci between city and mountain, and for the competitiveness of the urban milieu in association with its territory. Three spaces in three Alpine cities have been studied and compared from this perspective: the Curial ensemble in Chambéry, the new Thermal Baths of Meran and the renewal of Castelgrande in Bellinzona. From the critical observation of those three case studies and of the urban and architectural context of Covilhã, ensues the proposition of a methodology to approach the site of the ancient castle of Covilhã, focused on landscape, aiming for a successful intervention which will express the art of a place between city and mountain. Moreover, this proposition considers also the importance of architecture as an icon in the current context of urban competitiveness

Testo completoColleges in rural areas have a bad repute, as if the decline in the number of pupils were the sign of the decline of the academic level. The breaking-up of the educational system there may make us think the quality of the education itself is collapsing. Is the rural college the victim of the specific structure of its environment ? do these external factors weigh so much that they rob the pupils of any chance of success ? these small rural colleges in the academie of clermont-ferrand show the lack of moral and political reflection on what should be a fair system of education in these fragile areas suffering from a drop of the birthrate and an often negative migratory balance. This academie claims one of the highest percentages of small colleges nationwide. As some experts think 90 % of the population will live in 10% of the french territory in 2000, the particuliar problems of these colleges, far from being an impediment, give us the opportunity to think over what should be done for schools in thinly populated areas. We must therefore agree on a new principle, a new equitable contract, in which competition between schools, which are closely supervised by a centralized hierarchical authority, will be replaced by interschool cooperation

Testo completoThis thesis is dedicated to the study of a particular kind of shallow convection in the Cévennes area. This shallow convection is associated with orographic banded rainfall. Even if their intensity is small, they impact on hydrology since their duration. We hope to understand process linked with this rainfall and to evaluate their contribution to the rainfall regime in the area. The first step consists on the elaboration of a data base of orographic banded rainfall events. Indeed, until now, only 20h of orographic banded rainfall have been observed. This data base is built thanks to dynamical and rainfall criteria and then completed with linear and non-linear statistic methods. Next, the atmospheric conditions propice to the triggering of shallow convection are identified with radiosoundings, ERA40 reanalysis and numerical simulations (with MesoNH). Finally, the contribution of this rainfall is evaluated by comparing the accumulation of rainfall over the data base to the accumulation of rainfall over the whole period 1976-2005. Despite incertainties, this contribution is not negligible and suggests the interest to develop an observatory network to better observe the shallow orographic banded convective events

Testo completoFrom forelands to mountains…. Transitions from forelands to mountains are often astounding landmarks for an observer, who faces the mountain front while standing on a hilltop of a gently rolling landscape in its forefront. This perhaps formed the viewpoint of the poet whose pilgrims song starts, with “ I lift up mine eyes unto the mountains : from where shall my help come?”. Mountain fronts have formed a magnificent landmark, a secure stronghold for refuge, but also a major continental barrier for many early tribes and later-day explorers. This prominent morphological feature is not just an abrupt change in elevation and ruggedness of the landscape. In fact, as also this study shows, the uplift is even not limited to the mountains but may also affect the land-in-front (foreland). The subsurface of a mountain front holds a geology that is marked by a change from horizontally stratified sediments or rocks (strata) to strongly folded and faulted strata. Also other changes may be noted when descending deeper into the earth and zooming-out to the temperature structure and strength variations of large domaine of the Earth outer-shells, which are named as the crust and lithosphere. Mountains (orogens) are characterized by strongly deformed strata, and formed by the collision between lithosphere plates (known under the term plate-tectonics). An orogen contains an outermost crumble-zone in which contraction occurs by faulting and folding of strata. Thrusts are a special type of low-angle faults that carry strata as sheets over large horizontal distance, thus achieving shortening in the belt. The orogenic frontal belt is often referred to as a Foreland Fold-and-Thrust-Belt (or Forel)

Testo completoMountain biotas across the world are rich in species and also in endemics, suggesting that specific processes of diversification and survival were involved in their formation. In my thesis I focus on dynamics and drivers of plant diversification in the European mountains - a mountain system that is not among the worlds richest diversity hotspots, but is strikingly rich in the regional context, especially given its recent glaciation history. A lot has been written about diversification and glacial survival of specific lineages in the European mountain system, but so far it has been difficult to summarize these findings into a general picture. Here I benefit from recent advances in molecular and computational biology, allowing me to tackle evolutionary questions at a broader extent than previously possible, without severely compromising the resolution of the study. My thesis consists of three chapters:In the first chapter I explore relationships between patterns of endemism, evolutionary diversity, mountain topography and glaciation history in the Alps. I show here that there are two different types of endemic hotspots with dramatically different evolutionary histories – one in calcareous peripheral refugia conserving narrowly distributed and evolutionary isolated species, and another one in high elevations inhabited by phylogenetically clustered assemblages of species that are often endemic for the Alps, but relatively widespread within the Alpine arc.In the second chapter I focus on six lineages that quickly diversified in the European mountain system to explore their diversification in a comparative way. The diversification dynamics across the six lineages were relatively little impacted by the onset of Quaternary, likely because climatic oscillations were buffered by elevational migrations to mid elevation areas. Due to little affinity to elevational belts, the majority of the six lineages diversified allopatrically or across bedrock types, rather than parapatrically across elevational zones. A notable exception to this general pattern is Androsace sect. Aretia, which hosts multiple lineages of strict high elevation specialists.In the third chapter I focus on population structure and glacial survival of the high elevation species Androsace argentea. I show here that the population genetic structure of this species is driven by long distance dispersals followed by relatively little local gene flow, perhaps due to inefficiency of pollination. The populations in the internal Alps have variable origin and survival histories, ranging from long term in-situ survival to possibly post-glacial recolonization from Pyrenees.In conclusion, my results suggest that the diversification dynamics of the European mountain flora was surprisingly little impacted by the glaciation history. This is likely because a large portion of European mountain flora was surviving in peripheral refugia in mid- or low elevation areas, and has little affinity to the high elevation habitats severely impacted by glaciation. In contrast to this general pattern, there is a narrow set of true high elevation specialists that likely survived in-situ in high elevation areas. The major mode of speciation in the European mountain system was allopatry and our results from A. argentea suggest that at least in high elevation specialists it might have been stimulated by combination of frequent long distance dispersals coupled with little local gene flow

Testo completoConvergent zones show highly variable tectonical, morphological and thermal signatures. Some orogenic belts, like the Central Andes, locally undergo a neutral to extensive tectonic regime, while the whole belt is globally shortening. The balance between tectonic and buoyancy forces within the crust controls the dynamics of the margin. The physical parameters ruling the evolution of the margin can be deduced from topography; in the Andes, the involved stresses range between 25 MPa and 75 MPa, the total involved force is 5. 1012 N m-1, and the viscosity is in the order of 2. 1021 Pa s. A time-marching model is developed for the lithosphere, on the basis of the thin viscous sheet approximation. Minor differences in the boundary conditions conveniently explain the evolution of both compressive and extensive active plate margins. The impact of a denser lithospheric root on the dynamics is also explored. The tectonic evolution of active margins disturbs their thermal fields. Highly variable thermal signatures within orogenic belts are evidenced. Heat sources include static sources, i. E. Shear heating at the base of the lithosphere, magmatism, convective removal of the lithospheric root, erosion, sedimentation, etc. A theoretical approach is carried out in order to estimate the various thermal contributions and to assess their influences within different morphotectonic units. Particular attention is paid to surface processes. These investigations are applied to the Central Andes, where numerous thermal and additional geophysical information is available

Testo completoMicroorganisms play a crucial role in ecosystem processes. Understanding the spatio-temporal distribution of microbial communities is thus a central issue, especially in a context of global changes. Microorganisms are largely diverse, but given that the great part of them is still uncultured, the use of suitable tools is required to evaluate their huge diversity and the factors responsible for the community assembly. Alpine ecosystems display strong mesotopographical and snow cover regime gradients. These environmental gradients create a strong spatial heterogeneity in plant cover and ecosystem processes at reduced scales. Alpine tundra are also submitted to strong temporal contrasts, due the very low temperatures occurring during winter. These ecosystems are thus well suited to study the dynamic and spatial patterns of soil microbial communities. This work first focused on the improvement of a molecular fingerprint technique, CE-SSCP, but also on the development of statistical tools for the analysis of DNA sequences. Soil bacterial, fungal and crenarchaeal communities were followed up over two years by using CESSCP and cloning/sequencing, in two habitats contrasted by their snow cover regimes. This study was then extended at the landscape scale, under different plant covers. This work shows that microbial communities' assembly in alpine soils varies throughout seasons and that winter conditions constitute a strong selective event. This study also shows that microbial communities are spatially distributed according to snow cover regimes and plant cover. The factors directly involved in such patterns are discussed
