Abstract:

Dans le contexte actuel de changement climatique, la forêt est vue comme un puits de carbone, c’est-à-dire qu’elle contribue à stocker du C. Ce stockage peut s’effectuer à moyen terme dans la biomasse ligneuse et à plus long terme dans les sols. Afin de préserver les forêts et leur capacité de stockage, les gestionnaires forestiers se voient contraints d’effectuer de la régénération artificielle, c’est-à-dire de la plantation pour adapter les peuplements aux conditions futures. Pour assurer le succès de cette étape de plantation, il est parfois nécessaire de lever certaines contraintes comme l

Abstract:

Abstract The SOM in boreal forests contains non-living heterogeneous components resulting from microbial and chemical transformations of organic debris from plant litter. The major components in the plant biomass all decompose at different rates and therefore, contribute variably to the stable storages of soil C. The aims of the current thesis were 1) to explore how climate, soil fertility and initial litter quality affect the decomposition rate of litter, 2) to study how the different carbon fractions found in the plant litter relate to the quality and quantity of SOM in forest soils, 3) to d

Abstract:

Urbanisation is characterised by mass migration of people to urban areas and conversion of land from rural to urban land uses. Changes in population dynamics have led to half the world’s population living in urban areas; in developed countries, urban dwellers account for three-quarters of the total population. Though populations have shifted from rural to urban areas, people continue to rely on their environment, and trees in particular, for tangible and intangible benefits alike. A great deal of factual and anecdotal knowledge supports the role of trees for ecological, social, and economic

Abstract:

Digital soil mapping (DSM) relies on quantitative relationships between easily measured environmental covariates and field and laboratory data. We applied innovative sampling and inference techniques to predict the distribution of soil attributes, taxonomic classes, and dominant vegetation across a 30,000-ha complex Great Basin landscape in southwestern Utah. This arid rangeland was characterized by rugged topography, diverse vegetation, and intricate geology. Environmental covariates calculated from digital elevation models (DEM) and spectral satellite data were used to represent factors cont

Abstract:

The productivity of agricultural and forest ecosystems in regions at higher latitudes is to a large extent governed by low temperature and moisture conditions. Environmental conditions are acting both above- and below-ground and regulating carbon fluxes and evapotranspiration. However, the understanding of various feedbacks between vegetation and environmental conditions is still unclear. In this thesis, two studies were conducted to understand the physical and biological processes. In the first study, the aim was to simulate soil temperature and moisture dynamics in the bare soil with seasona

Abstract:

In the wetter climates associated with the coastal forests of northwestern North America, coarse woody debris (CWD) accumulations in the form of snags, downed boles, and large branches can be large in natural forest ecosystems. Seedlings often regenerate on stumps and downed logs in the understory of old-growth coastal forests. The question remains though, whether CWD is a necessary component for seedling survival and growth in forests managed for commodity production. This study addresses one concern of forest managers: is there an immediate nutritional or moisture supply advantage conferr

The objective of the reasearch was analysing the long-term effects of the centennial activity of charcoal production on forest ecosystems of the Mediterranean area. The study is structured in order to achieve three main aims: i) evaluating the impact of kiln sites on the forest vegetation (tree, shrubs and herbaceous species) in relation to abiotic factors; ii) examine the effects of the charcoal-enriched kiln site soil on the early life stages of major forest trees; iii) quantifying and characterizing the legacy of such activity at the landscape level, through the analysis of the distribution
