Texto completo da fonteHuman activities are at the root of an unprecedented biodiversity crisis. Migratoryspecies are particularly at risk, because migration is risky and makesthese species dependent on multiple environments and their connectivity. Phenology,i.e. the timing at which a species completes an event of its life cycle,has a strong influence on the overall cost of that event. In this thesis, I focuson the phenology of the first seaward migration of Atlantic salmon (Salmosalar, A. salmon), a crucial event in its life cycle. Climate change is increasing lydisrupting the phenology of many species, including migratory species. Inparticular, it is altering the life-history traits and environmental cues that triggermigration. This can result in asynchrony between the conditions required by the species during, or following, the migration in question. Understandingthe mechanisms underlying phenological changes is essential for predicting theimpact that these disturbances could have on species. However, these mechanismsremain poorly understood due to incomplete data and/or inadequateapproaches to their statistical analysis. To study the first seaward migration ofA. salmon, I used long-term (25 years) mark-recapture monitoring in the Scorffriver (Brittany, France). Data collected in the natural environment are subjectto variations in the observation process that can mask or bias our understandingof the underlying biological processes. This is particularly important whenan environmental factor (such as flow rate) influences both the observation (forexample, the effectiveness of a trap) and the biological process (triggering ofmigration). To avoid misinterpretations, I propose a hierarchical, mechanisticBayesian modelling approach that explicitly separates the observation process(capture efficiency) and the dynamic process of interest (migration phenology),both of which are influenced by different effects of environmental factors. Afirst model provides an estimate of capture probabilities and their variationsover time, which are then used in a second model to identify the mechanisms ofmigration phenology. This second model highlights the importance of temperature,discharge and discharge variation in the migration decision. These factorsmay be disrupted by climate change, so I conclude by exploring the possibleconsequences of climate change on the phenology and size of young salmonduring their migration to the sea, both of which are crucial to their fitness. Mythesis highlights the importance of mechanistic modelling in understandingchanges in phenology, and offers an additional perspective for understandingthe ongoing decline in Atlantic salmon populations

Texto completo da fonteThe land surface component of the carbon cycle exhibits a large geographical disparity as well as a large interannual variability. It is important to survey and also to try predicting the evolution of this sink in response to climate change and human activities. A good knowledge of the physics of the satellite measurement allows us to model the land surface directional effects and thus to remove them from the measurement. We then construct less noisy time series of vegetation indices over almost three decades, from which we extract phenological parameters, phenology being the study of key-stages of the vegetal annual cycle in relation to climate. These satellite data may also be used for global vegetation models: to validate the modeled Leaf Area Index; to be assimilated and thus help improve the carbon fluxes budget; to calibrate phenological models

Texto completo da fonteBudburst phenology is a major adaptive trait of trees to the environment in temperateclimate. Our aim was to characterize the biotic (powdery mildew) and abiotic (winter and springtemperatures / spring frost) constraints acting on budburst in view to explain the patterns of intra and interpopulations’ phenological variation observed in sessile oak (Quercus petraea) along an elevation gradient.We based our approach on in situ monitoring, experimentation and modeling. Our results highlight that theavoidance of late spring frosts is a major adaptive trait along the elevation gradient. The lateness inbudburst might be due to higher requirements in forcing temperatures. Otherwise, the fungus is not locallyadapted to its host phenology so oak individuals and populations are unequally exposed to the disease.With increasing elevation, oaks are more and more exposed to the fungus, but the environmental factorsare unfavorable to higher infection. At low elevation, powdery mildew and late spring frosts favor oppositephonological phenotypes (early-flushing vs. late-flushing trees, respectively); the combination of the twopressures may thus contribute to the maintenance of the observed high phenological diversity. We alsoshowed that powdery mildew infection induced an increased polycyclism during the growing season in oakseedlings, which made them less resistant to winter frosts. Predictive phenological models will have toinclude the chilling phase which conditions dormancy breaking. Although the lack of chilling is not yet alimiting factor, the current trend in increasingly advanced budburst will certainly be slowed or even reversedin the middle of the century at low elevation, in the southern margin of the distribution area of Q. petraea

Texto completo da fonteDuring winter, ice or snow presence on the road might have serious consequences on road traffic. To develop a decision-making tool for road management in winter, a numerical model which permits to simulate snow behaviour on roads was developed. It results from the coupling of the ISBA and CROCUS models, which are respectively the soil and snow model of Météo-France. This model was validated thanks to observed snow on road events, resulting from a previous experimental field campaign led on the Météo-France experimental station located at the Col de Porte (1320m, Isère). The validation was first done with the meteorological data measured on the site, and then with forecasted data. Results of the forecast on the experimental site were satisfactory, so the model was spatialized at the France scale, with a 8km grid resolution. The 2004/05 winter, with many snow on road events, was simulated. The validation was done thanks to road station data from several Highways and thanks to measurement from the Météo-France stations network

Texto completo da fonteIn environmental acoustics there is today a need for models to predict sound propagation at long ranges. Meteorological effects become then important. This work aimed to develop a model for complex atmospheric sound propagation above uneven absorbing grounds. We have derived a new model : Meteo-BEM, based on one hand on the boundary element method, that allows the assessment of any kind of shape and absorption of the propagation-domain, and on the other hand on recent propagation models in inhomogeneous media. The formulation relies on the layer potentials theory. The Green's function used is based on the normal modes solution for downward refraction, and in the case of upward refraction, on the residue series solution in the shadow zone and on the geometrical model in the illuminated region. In order to illustrate this new approach, the case of a thin rigid screen, on a reflecting and on an absorbing ground, is studied, under various refracting conditions. The model is first compared for validation to numerical and experimental results coming from the literature. Then measurements undertaken in laboratory above curved surfaces are presented. The good agreement between calculated and measured datas for downward refraction shows that meteorological effects can be included in a boundary element method
