Testo completoThe environment depends on physical and biological processes that are still poorly understood and intimately related to a local scale. There is a need to model environmental variables in many impact studies. Environmental modelling requires “flexible” approaches taking into account local factors that are at least as important as climate factors. From the standpoint of statistics, this thesis aim was to estimate a “statistical link” between climate and environment. This relationship can associate local and large spatial scales to quickly assess the ability of several climate models to represent environmental variables. High resolution modelling of a spatially heterogeneous variable such as permafrost allowed a better interpretation and a better evaluation of the results. Such a statistical link can also reformulate some “environmental physics” taking climatic signal and various types of information (e. G. , continentality) into account. Statistics allow for example to model the complexity of an environmental variable such as vegetation, which is difficult to represent by dynamical approaches. Using a statistical model adapted to the study of vegetation led us to provide a new global database of the potential vegetation and to entail many prospects in paleoclimatology

Testo completoHarsh environmental conditions encountered in North Atlantic during wintertime, characterized by frequent extreme weather events, are among the most challenging constraints for endothermic animals. Seabirds, which experience this environment for many months per year, play a central role in North Atlantic food webs, notably as top predators and indicators of marine ecosystems. In the current context of climate change, pronounced in North Atlantic waters, it is therefore a major objective to understand how seabirds respond and adapt to these environmental constraints shaping their survival and their population dynamics. We used a multidisciplinary approach (combining microelectronics, stable isotopic analyses, bioenergetics modelling and demography) focused on individual energy balance, to study the ecophysiological plasticity of the 3 main alcid species of the North Atlantic. We found that harsh winter conditions induce an energetic bottleneck for seabirds which might explain recurrent events of winter mass mortality, so called ‘seabird winter wrecks'. In response to increased energy expenditure, we showed that seabirds can adopt different strategies allowing higher energy intake. They can modulate their vertical (diving behaviour) and/or horizontal (migration) movements, as well as their trophic status, depending on the spatial and temporal availability of their prey. All together, these results constitute one of the first comprehensive studies of seabird winter ecology. These insights are essential to a better understanding of their population dynamics and constitute a firm foundation to future investigations of the impact of climate change on marine top predators

Testo completoIn the face of evergrowing global deforestation, numerous forest protection and restoration projects have been deployed at the international scale. The goal of this thesis is to provide adaptation planning in the vulnerable tropical semi-arid regions with scientific material about reforestation project constraints and opportunities at the global scale, inthe context of climate change. The literature review (chapter 1) confirms that reforestation projects aimed at warmingmitigation hold a better chance of success under tropical lattitudes. Indeed, both biochemical and biophysical effects of the vegetation on climate converge toward a global cooling effect. As reforestation in tropical semi-arid regions aims at satisfying various ecosystemic services, it holds beneficial promises at both the global and the local scale. However, due to scarce water resources, implementing a tree cover in semi-arid conditions could turn out unsustainable in the long run. A bioclimatological is applied, in chapter 2, to a multimodel ensemble of projections in order to draw the evolution of global tropical semi-arid territory under several climate change scenarios (RCP). The present tropical semi-arid territory is expected to remain mostly so in future conditions. However, up to 25% of the this territory on average will evolve towards arider conditions, and up to 11% towards wetter conditions. Nevertheless, the tropical semi-arid territory will increase by the end of the 21st century, by up to 13% on average (RCP 8.5). This increase results from a migration outside of the tropical belt, consistent with the Hadley circulation widening hypothesis under climate change. Chapter 3 proposes a methodology aimed at analysing the implications of this evolution for the climatic potential of tree cover sustainability. The global vegetation model (ORCHIDEE, developed at IPSL), used to simulate this potential, accounts mechanistically for all the climatic factors of the plant's growth. A typology of result profiles from the simulation experiments partitions the territory into subregions characterized by a specific relation between the tree development and the tree cover density: five types range from the least (Type 1) to the most (Type 4) favourable ones. A reference experiment is performed using observational climate data (from the Climatic Research Unit). Covering almost half of the territory, Type 1 is characterized by the impossibility to maintain a tree cover for the highest cover densities. The second type in order of surface occupation is Type 4 (28% of the territory). More favourable, it is characterized by high tree development for any tree cover density. The "tree cover potential" of each type is characterized by its optimum: the tree cover density that realises the best compromise between tree development and total productivity. In Chapter 4, the same methodology is applied to future climate projections for RCP 8.5. The ORCHIDEE model is thus forced with global climate model outputs, for the beginning and the end of the 21st century. By the end of the century, Type 1 represents no more than 25% of the tropical semi-arid territory on average, while Type 4 becomes the dominant one (49% of the territory). Because of the stability of the tree cover potential whithin each type, the evolution toward a more or less favourable type can be directly interpreted in terms of an increasing or a decreasing potential. The results show that the tree cover potential in the tropical semi-arid territory does not systematically suffer from the general decrease that could be expected from increasing aridity. A complementary experiment suggests that the main reason for this result lies is the atmospheric CO2 fertilization effect. Interpreting these results for reforestation strategy recommandations, suggests that, for the long term, areas of the tropical semi-arid territory where reforestation would be advised against are overall relatively small
