Texto completo da fonteThis work aimed (1) at characterizing the impact of planting density (PD) and pedoclimatic conditions (sites) on the physiology of poplar and willow dedicated to biomass production, (2) at evaluating the genetic variability of productivity-related traits, water-use efficiency (WUE) and nitrogen-use efficiency (NUE) in a perspective of plant breeding, and (3) at assessing the relationships among these traits. Four experimental plantations were established in northern France. Our results show that PD affects biomass production and WUE depending on sites. Under most favorable growth conditions, trees grown at higher density displayed taller stems, lower stem circumference, and lower WUE, than trees grown at lower density indicating that increased tree density mainly accentuated competition for light. Under less favorable conditions, an increase of PD involved higher WUE and lower stem circumference, likely because of an increased competition for water. Positive links between biomass production and WUE were detected for poplar and willow under environmental conditions where competition for resources was reduced. A large canopy is associated to potentially more important transpiration water losses at plant level. This could be compensated at leaf level through a better stomatal regulation. The absence of antagonism between biomass production, WUE, and NUE suggests the possibility to select genotypes for these three traits independently. Moreover, the Genotype x Site interactions indicated the difficulty to identify good genotypes for a large set of site conditions suggesting that the selection has to be realized depending on the site conditions

Texto completo da fontePlantations of fast-growing species (e.g. poplars, willows, eucalyptus) are widely used for biomass supply. However, these plantations are often monospecific systems and are generally very resource demanding. This is particularly the case for plantations of species belonging to the Populus genus, which can be grown under intensive cultivation conditions, and which use large quantities of water and nitrogen to produce large volumes of biomass. In this context, mixed forest or agroforestry plantations appear as an interesting alternative to monocultures. Indeed, they can produce more by using more efficiently the resources necessary for the growth of the different components of the mixture by playing on the complementarity between the species. The introduction of nitrogen-fixing species in these mixtures can also be an additional asset to reduce the need for synthetic nitrogen inputs.In any plantation, forest or agroforestry, intraspecific interactions (individuals of the same species) or interspecific interactions (between individuals of two different species) can be negative, positive, or neutral. To date, the interactions between species that determine whether a given mixture will be more productive than the corresponding monocultures are still poorly understood and studies of their impact on resource-use efficiency are scarce. The overall objective of the PhD work was to evaluate the impact of several species mixtures, both forest and agroforestry, on tree growth performance through effects on functional (resource-use efficiencies), structural (crown architecture) and phenological (spring and fall bud and leaf phenology) determinants. The main hypothesis was that thanks to symbiotic nitrogen fixation and complementarity between species, trees in mixtures would be more productive and use resources more efficiently than in monoculture.This objective was pursued on an instrumented plantation on the La Bouzule site (54), installed in spring 2014, composed of mixtures of woody (poplars and alders) and herbaceous (legumes, graminoids) species, as well as their respective monocultures. The functioning of three types of mixtures including nitrogen-fixing species (poplars/alfalfa - clover succession; poplars/alders; alders/cereal - temporary grassland succession) was compared with monocultures of the two woody species. The originality of the work lies on the combination of the study of processes occurring at the organ and tree scales to describe the interaction processes between species and the overall performance of the different types of mixtures, compared to their respective monocultures.Species interactions in a plantation are not static but change as the stand develops. The nature of the interactions between poplars and legumes in the agroforestry plot evolved from a predominant competition at the beginning of the plantation to facilitation through soil nitrogen enrichment. The growth performances of the poplars were increased compared to the monoculture, associated with a higher water-use efficiency than in monoculture and a reduction of competition between the canopies allowing a better interception of light in agroforestry. In contrast, higher water-use efficiency of poplars associated with alder than in monoculture was not associated with better growth performances of both species compared to their respective monocultures. Overall, alder was only slightly affected by the mixtures

Texto completo da fonteKef is a region of Tunisia not so studied among researchers. Water availability, studied from the qualitative and quantitative point of view requires crossing obvious variables such as hydrogeology, climatology, but also socio-economic or cultural variables. This research took into account the importance of the working scale, replacing Kef context in Tunisia national context before focusing on the specifics of this governorate. It shows the importance of water resources in the socio-economic development of Tunisia and Kef in particular. Water resources in Kef are important and of good qualities: well used, they should speed up the development of agriculture and industry. Moreover, the interesting potential of thermal and mineral water provides another economical alternative which could allow development of environmental friendly mountain and thermal tourism

Texto completo da fonteCompared to monocultures, agroforestry systems (AFS) are expected to provide enhanced resource-use efficiency and larger ecosystem services. However, due to the complexity of the interactions occurring in AFS, it is challenging to quantify and decompose the effects of shade trees on the main crop net primary productivity (NPP). Few process-based models are able to analyze the interactions between crop and shade trees for carbon and water. Interactions for light, water and energy occurring between tree and crops might have counterintuitive effects on photosynthesis, light use efficiency (LUE), transpiration efficiency and microclimate. We showed that a 3D process-based model, MAESPA, was able to quantitatively describe the spatial variability of those processes from the plant to the plot, and from hourly to yearly timescales. MAESPA simulated satisfactorily light interception in a 2-layer heterogeneous coffee AFS. It was used to produce powerful explanatory variables in AFS experiments and to analyze the determinants of coffee plant NPP. LUE displayed a 2-fold increase for shaded coffee plants totally compensating the expected decrease of local irradiance interception, and coffee plant ANPP was the same below shade trees or in the open. MAESPA also simulated satisfactorily carbon exchange at whole plant and plot scales, when compared to gas exchange records in a whole-plant chamber, or with eddy-covariance records above the canopy. We used MAESPA to simulate the spatial variability of photosynthesis and LUE. Overall, MAESPA proved to be a relevant model to quantify spatial interactions. The next very relevant development would be to couple it to a model of carbon allocation among organs in the coffee plants

Texto completo da fonteWithin universal health systems, the lack of information regarding resource utilisation for acute traumatic brain injury (TBI) care impedes efforts to improve the quality and efficiency of care in this patient population. To address this knowledge gap, a multicenter retrospective cohort study was conducted in the province of Quebec. The objectives of this study were to evaluate the inter-hospital variation in resource use for TBI admissions, identify patient-level determinants of resource use intensity and evaluate the association between hospital resource use and clinical outcomes for TBI admissions. We included all patients aged 16 and over hospitalized following a TBI in any of 57 the adult trauma centers in Quebec between 2013 and 2016. Overall, the inter-hospital variation in resource use was statically significant. However, when we stratified by activity centers, the operating room and para-clinical services had the highest inter-hospital variations. Inter-hospital variation was greater for patients under 65 years of age and those with severe TBI. Comorbidities, anatomical injury severity, and a transfer to long-term center care following hospital discharge were identified as determinants of high resource use intensity. On a hospital level, high resource use was associated with a low incidence of mortality but a high incidence of complications. This study advances knowledge on resource use in TBI populations. However, further studies should be conducted to determine the factors responsible for inter-hospital variations in resource use including process of care, physician characteristics and trauma center structure.
