Full textTimber study makes it possible to date the traditional buildings (farms, barns, wine presses, mills, bridge ...) and specify the time variations of relationships between human societies, timber uses and forest management. The studied area is the Durance valley, from Briançon to Riez region, and, more generally, the southern French Alps. The time windowof our study is the medieval times, modern and contemporary periods, when a large amount of material (wood) is available.The first purpose of my work is to establish a better knowledge of the built heritage, using dendrochronology. We have been highlighting the types of wood used (species, age, size) as well as the trees felling and human construction phases. Given the human occupation and the land use changes, the development of this type of study is essential to preserve the historical track of this fragile heritage, witness of a mountain society in strong relationship with its environment, especially forestry. The second purpose is to develop knowledge of the relationship between buildings and forest. This relationship addresses the issue of the Alpine forests state and forest as a resource, during the last millennium. Human occupation history, in the southern French Alps, is questioned.To reach these goals, interdisciplinarity has been a necessity. Thus, a dialogue was established with historians, archaeologists, foresters, computer specialists, carpenters, anthracologists, managers, engineers and workers in construction and restoration. In order to overcome the limits of each discipline, dendrochronology has been used to implement an interdisciplinary approach

Full textHumus is the place of key tree nutrition processes. However, it remains a compartment of the ecosystem still under studied for all major nutrients and beneficial elements other than C and N. Thus, in a context of increasing pressure on forests, it matters to understand the dynamics of the elements from their input into the humus to their output towards the soil. The aims of this thesis are: (1) to identify the mechanisms and factors responsible of the major element dynamics (C, N, P, K, Ca, Mg, Mn, S, Si, Al and Fe), (2) to determine the relationships between these elements and (3) to specify the place of the humus in tree nutrition. To answer these objectives, a conceptual model based on the identification of humus inputs and outputs and the possible mechanisms present at the humus level was elaborated. The results of this thesis suggest that the element output fluxes depends on processes and reactions accelerating or delaying their release from the humus. The element release rates in the soil depend on their forms in the humus inputs (soluble, organic molecules, biominerals) and their location in the plant tissues (leaf blade vs. vein) supplying the humus. The element dynamics is also influenced by recycling reactions within the humus, such as biotic or abiotic precipitation through testate amoebae (Si, P, Ca and Mn), precipitates around hyphae (Ca, Mn, P, and K) or amorphous Si precipitates. These reactions control the mean residence times of the elements and their leaching gradient below the humus: the most soluble and least immobilized elements will be leached more rapidly and will have lower residence time. The release of these elements below the humus is another important factor that affects the availability of these elements to trees. During the growing season, when the trees upatke soil solution, less than 25% of K and P are released from humus. The ability of the soil to hold the elements produced during periods of senescence and dormancy is fundamental to ensure the sustainability of the ecosystem. In this thesis, the particles leaving the humus were quantified for the first time. In addition to their role on pedogenesis and the dynamics of C, this particle flux below the humus could increase the cation-exchange capacity of the soil and its ability to hold these leached elements during the dormant period

Full textHaving replaced The Mount Ventoux in its geographic and geologic frame, the Reduviidae are presented briefly on morphological (eggs, young stadia, adults), ecological (food, camouflage) and systematical plans. The ethology, mainly returned to the alimentary behavior, is studied in detail. It is shown that the food catching can be decomposed in eight obligatory phases : detection of the victim, approach, interest, attack, sting, immobilization, alimentation properly and cleaning ; sometimes one notes a supplementary phase : transport (after immobilization). The phases interest, during which the potential prey will be or not considered consumable, and immobilization, while the prey is dying, had been never indicated previously in these Insects. The phases sting and food can be distinguished by the place of the point of puncture ; often sting (during which the lethal saliva is injected) is practised wherever : while food puncture is always practised in a precise place, variable according to the prey species. In the case of harmless preys, one phase is often shortened and the passage from one phase to another one is accelerated. Problably, in harmless preys, alimentation begins during immobilization. The harmless preys are probably punctured during the immobilization. It as been possible to count thirteen species at the Ventoux, ten of which belonging to the Harpactorinae. For some of them, eggs and young stadia are described, often for the first time. The conditions of the collects are precised and the annual biologic cycle is established. The list of the preys of eight Reduviidae (of which numerous news) is supplied. A fine study of female genitalias of "Peirates stridulus" and "P. Hybridus" is given which allows to separate certainly these taxa. The new synonymy "Sphedanolestes livigaster " (Mulsant & Tey, 1852) = "S. Argenteolineatus" (A. Costa, 1883) is established. Precisions on the bio-ecology of Coreoidea from Mont Ventoux are brought and particularly their elevation which is compared to some of others European mounts

Full textThe use of liming (Ca-Mg) on acidified forest can be interesting to counteract soil acidification and loss of nutrients caused by decades of acid atmospheric deposition. In this context, the aims of this work were to assess liming effect on (i) taxonomical diversity and community structure of soil macro-invertebrates and on (ii) two associated functional processes related to earthworms: soil structuration and humus evolution. The PhD project was realised in three sites from the Vosges mountains (North-eastern, France): two forest mountain catchments (one lying on sandstone and the other on granite) limed in 2003 and the public hill forest of Humont at a lower altitude limed in 1991 and 2008. Results showed that 4 years after liming in mountain forest, the total abundance of macro-invertebrates decreased, while the species richness were similar. However, the community structure strongly differed, and less than 50% of the species were common to limed and control sites. Moreover, 43 species appeared to be indicators of liming. Predator taxa abundance decreased whereas the detritivorous were favoured by lime addition. The in vitro experiments showed a positive effect of liming on soil structuration by earthworm activities (cast production and burrowing activities). In the Humont forest, liming at medium-term (4 years) and long term (20 years) have an important effect on the Aporrectodea velox population, an endemic vosgian species. Related to its high biomass, this increase strongly improved soil physicochemical parameters such as soil structure and humus morphology
