Electronic Thesis or Diss., Bourgogne Franche-Comté, 2024. https://theses.hal.science/tel-04882870.
Testo completoCurrent climate change and shifts in land use and management are likely to alter the dynamics of soil organic matter decomposition and associated carbon fluxes. Forest ecosystems account for 40 % of the organic carbon stock on continental surfaces and are therefore a priority for research. Locally, the Morvan, a mid-mountain region covered by 45% forest, appears to be more sensitive to climate change than the surrounding plains. In this context, this study focused on the dynamics of organic carbon in temperate forest soils in the face of climate change. This work was mainly carried out on the Mont Beuvray site, a forested massif located in the southern part of the Morvan Regional Natural Park. Soil samples representing the spatial diversity of the massif were taken for each tree species (beech, Douglas fir, silver fir, spruce). The molecular diversity of organic matter was characterised by pyrolysis coupled with gas chromatography-mass spectrometry (Py-GC-MS). The results suggest that organic matter in soils under silver fir is more readily degradable than that in soils under Douglas fir. The temperature sensitivity of soil respiration was assessed by measuring the Q10 parameter, with values ranging from 2.3 to 3.0. A higher value was observed for beech (2.8 ± 0.1) compared to conifers (2.6 ± 0.1). This suggests that with climate change, soils under deciduous species could emit more CO2 than soils under conifers. The observed variability in this Q10 parameter is mainly explained by the interaction between the molecular composition of organic matter and the activity of microorganisms (extracellular enzymatic activities). These results will help to better assess and anticipate changes in the dynamics of organic matter in mid-mountain forest soils

Testo completoThe purpose of this thesis is to identify human occupation and exploitation of the environment of marginal territories in the Livradois-Forez, which include the cities of Arverne, Segusiave, and Vellave, and to investigate the regional integration of these localities from the second Iron Age to the Early Middle Age. This thesis is conducted from a dynamic, diachronic, and systemic perspective, and utilizes a landscape archaeology approach to explore the relations between societies, in particular their economies, and the environment. The research presented crosses archaeology and the environmental sciences in order to increase knowledge of the setting in which these societies evolved and the possible human influences on it, but it also identifies social-economic and cultural processes. The completion of this project required three stages: first, the integration of research and syntheses developed from research programs in which I collaborated; second, the synthesis of the archaeological data; third, the acquisition of new data through archaeological field surveys and through the analysis of plant macrofossils from peatlands. Four sectors that reflect key components of the landscape have been used. As far as possible, research in each sector included archaeological surveys and paleoenvironmental research. Interdisciplinary archaeological, paleoecological, and geoarchaeological studies, combined with GIS, exhibit a heterogenous development that can be seen in two economic cycles: the first, from the Second Iron Age to the High Roman Empire; the second, from the Late Roman Empire to the Early Middle Age. For each economic cycle, human land use and the exploitation of the environment reflect strategies and social-economic choices driven by topography, climate, and available resources (particularly agricultural resources, but also the presence of wood and ore). The proximity of routes of communication reflects important pools of population and the centers of the three cities. Each stage of environmental exploitation is marked by an increase of erosion, peat initiation, and changes in the use of the oldest peatland. Finally, this border area seems to be integrated into the regional economy.

Testo completoInula montana L. is used in traditional medicine of the Mediterranean region.Phytochemical study led to the isolation and identification of 28 compounds from flowers and leaves of Inula montana L. These compounds belong to the family of terpenes, polyphenols, and inositol derivatives.Six of them are new compounds: one new sesquiterpene acid, called Eldarin and five inositol derivatives.Nineteen compounds are reported for the first time in Inula montana.A quality control monography of flowers from Inula montana was established. Two methods of qualitative and quantitative analysis by UHPLC were developed and validated. The first method concerns the profile of sesquiterpene lactones with the quantification of Costunolide. The second method concerns the polyphenols profile with the quantitative evaluation of three compounds. These two methods of analysis by UHPLC allow to conduct the comparative study of wild and cultivated plant.These methods were also used for the comparative study of plants, subjected to different stress, such as salt and UV-B. The vegetal material obtained by in vitro culture was also analyzed by these methods.The active eco-extracts have been developed through the design of experiments by extraction assisted by microwaves and ultrasounds, using green solvents.The anti-inflammatory activity of different extracts and compounds of Inula montana was evaluated in vitro. The extracts and compounds show important activity. Activity of tinctures from Inula montana are similar to the activity of tinctures from Arnica montana.The phytochemical and pharmacological studies show that Inula montana could be proposed as an alternative to Arnica montana

Testo completoThe "Parc naturel régional de la Brenne" (Regional Natural Park- PNR) was built around a focal point - the ponds and lakes of the Grande Brenne - which gradually became an integral part of its identity. The Brenne pond, with its characteristic sluice gates, reeds and birdlife, thus represents the archetypal landscape ofthe area. This iconic landscape, our perception of which has drastically changed since the 18th century, has now become a source of local pride, both promoted by the Park authorities and sought after by visitors. However, some landscape mutations,which are intimately related to the emergence of new practices, are threatening the Brenne's landscape identity. Moreover, the reexist other, less valued landscapes around the Grande Brenne which have issues of their own. When the time came to redefine the objectives of the Charter(2008), the Park's representatives noticed discrepancies in terms of landscape, territory and identity. They decided to "highlight thePark's landscape disparity" and find a common theme which would help consider the territory as a coherent whole. This action research thesis proposes to approach the problem from a landscape perspective, analyzing individual and collective representations of landscapes and - beyond them - territories. Thanks to participative activities run over 26 months, local people, visitors, elected representatives, Park employees and spatial planning experts were invited to question themselves about the Park's landscapes through the use of photography and to formulate and share their points of view. These activities and landscape mediation efforts have led to the creation of a participative photographic observatory of landscapes - a photographic itinerary which provides the Park with an operational tool for monitoring its landscapes

Testo completoThis thesis is a contribution to the study of relationships between landscape dynamics and land use changes in mountains of the French Alps. The functioning of the mosaic of forest ecosystems and grazing areas are of major concern for the nature reserve managers. The area which has been created in 1985 and offers a great variety of landscapes and is considered as hotspot for biodiversity. Human activities like grazing and forest harvesting have influence the structure and functioning of the landscapes for thousands of years. The northern part of the reserve is densely covered with forests while the eastern and southern parts consist of a mosaic of clearings, woodlands and pastures. Landspace ecology tools and cadastral survey have been used to follow up the evolution of the landscape over the past two centuries. The management of the area is driven by the fact that the actual major tendency is a closing of the landscape on the whole territory which has an impact on human activities like grazing practices. Because of the multiple actors that are involved in the management of the area, well balanced series of conservation measures are necessary like keeping the heterogeneity by maintaining unmanaged and managed areas. Locally, more intense management operations could be planned. Complementary studies and surveys are also necessary when considering that the area will be included in the network of sites of scientific interest. For the coming years, it will also help decision-making policies

Testo completoThe central assumption put forward that in territorialized identity construction processes, social group memories would have a central role to play. It is why we propose a contribution to a "sociology of signs" as an analysis of what is produced by spatial marking of memory. The regional nature park of Verdon, created in 1997 in the south-east of France, is our field of investigation. After a theoretical approach on the foundations of thought wich link memory and territory, reffering in particular to Maurice Halbwachs works (part1), we will describe the history of both physical and symbolic construction of the Verdon territories (part 2). The role of hydroelectric area, are the two central poles of a specific territorial character where more than memory, it is oblivion wich seems to prevail. How consequently, can the regional nature park of Verdon appear as territory in this area with differentiated links with past (part 3) ? The appeal to nature seems to be a possible referent of local identity

Testo completoThe retro-arc foreland basin of the Central Andes is considered as a type-example of a foreland basin system (Horton & DeCelles, 1997). Three regions have been studied : the North Amazonian basin (3-8ʿS), the South Amazonian basin (11-12ʿS) and the south-eastern Bolivian basin (19-20ʿS). The foreland basin system of the Central Andes constitutes a favoured area where studies of the deformation and sedimentary fill can be coupled. This study enabled us to arrive at a clearer understanding of the longitudinal and latitudinal structural/sedimentary evolutions and of the tectono-sedimentary dynamics of the basin and adjacent orogen, and to a sequential restoration of the basins at key-periods in the evolution of the range from the Eocene to present-day. During the early and middle Eocene, the Western Cordillera of northern Peru between 3 and 8ʿS experienced large uplift and erosion. This event is interpreted as a stage of tectonic quiescence and erosional unloading. To the south of 11ʿS, no such event is recorded in the sedimentary fill and the sedimentary arrangement indicates the development of a flexural basin related to orogenic loading. Because the North Amazonian foreland basin system is situated at the junction between the Central Andes and the Northern Andes, this change in the geodynamic process can be ascribed to the interference with the Northern Andes. .

Testo completoFirst part : study of visual and geographical components of landscapes, along a sequence of a journey which opens on the placement in a prominent position the organizational and functional logics of space. Second part : out lining the logics of evolution of landscapes from the demographic maximum of the beginning of the nineteenth century. We study : the changes of the agro-sylvo-pastoral system, the evolution of the soil occupation, the recolonization of the forest and the meadows dynamic. Third part : research of visual indicators of landscape evolution and elaboration of constrasting scenarii of socio-economic evolution whose landscape consequences are discussed
