▼ Depuis la seconde moitié du XXème siècle, l'utilisation massive des engrais desynthèse a contribué à l’augmentation des rendements mais aussi à l’accumulation d’élémentsminéraux dans les systèmes agricoles. La limitation de cette accumulation passe par unmeilleur recyclage des éléments minéraux déjà présents dans les systèmes agricoles.L'agriculture biologique, qui interdit le recours aux engrais de synthèse, peut être considéréecomme un prototype d’agriculture à même d’améliorer ce recyclage. L’objectif de cette thèse a été d’identifier les stratégies mises en place par les agriculteurs biologiques pour s’approvisionner en éléments minéraux. Cet objectif a été décliné en sous-objectifs qui ont été(i) d’identifier les pratiques d’approvisionnement en fertilisants et aliments des agriculteursbiologiques, (ii) d’en comprendre les déterminants et (iii) d’évaluer la performance de ces pratiques vis-à-vis du recyclage de l’azote, du phosphore et du potassium. Pour ce faire, 63exploitations biologiques ont été enquêtées afin de recueillir des données concernant la natureet la quantité des matières échangées, ainsi que les fournisseurs et les collecteurs en relation avec ces exploitations. Afin d’étudier l’influence du contexte local, les enquêtes ont été menées dans trois régions agricoles sélectionnées en fonction de leur degré de spécialisation (productions végétales, productions animales et mixte). L’intensité du recyclagelocal a été évaluée grâce à deux indicateurs : l’autonomie, définie comme le ratio entre laquantité d’éléments minéraux provenant d’échanges entre exploitations et la quantité totale d’éléments minéraux entrant dans les exploitations biologiques de la région, et le degré de bouclage des cycles, défini comme la proportion d'éléments minéraux passant au moins deux fois par la même exploitation au sein de la région étudiée. Un premier niveau d’analyse, àl’échelle de l’exploitation, a mis en évidence les déterminants de l’approvisionnement en éléments minéraux des exploitations biologiques. Il a montré que les exploitations biologiques spécialisées dans les productions végétales importaient des quantités importantes defertilisants organiques en provenance de l’agriculture conventionnelle. Un second niveau d’analyse, à l’échelle régionale, a montré que la proximité entre des exploitations agricoles spécialisées dans les productions végétales et d’autres spécialisées dans les productions animales favorisait les échanges entre ces exploitations. Ces échanges permettaient d’améliorer l’autonomie locale même si le degré de bouclage des cycles restait faible. Enfin, une approche par modélisation a permis de quantifier la fraction du phosphore des produits biologiques qui dérive des engrais de synthèse, notamment suite aux échanges entre lesexploitations biologiques et conventionnelles. Plus de deux tiers du phosphore composant les productions biologiques étaient du phosphore initialement issu d’apports d’engrais de synthèse. Les résultats obtenus dans cette thèse ont permis de discuter des forme d’organisation… Advisors/Committee Members: Pellerin, Sylvain (thesis director), Nesme, Thomas (thesis director).

▼ Ecological stability is a multifaceted concept, incorporating components such as variability, resistance, resilience, persistence, and robustness. Understanding and predicting the relationships among these many components of stability is fundamental to the optimal management of both biodiversity and ecosystem functioning. In spite of this, the multidimensionality of ecological stability remains remarkably understudied, with most research focussing on one or two components in isolation. We know worryingly little about the mechanisms underpinning relationships among components of stability and whether there are any general features of these that are common across different types of ecosystem or disturbance. In this thesis, I explore the effect of perturbations on both the relationships between stability components and the predictability of these components. In Chapter 2, I examine the effects of perturbation intensity using theoretical simulations. By analysing the dynamics of food-webs following perturbations of different strengths, I discover that the predictability of stability components and the strength of relationships between them decrease with increasing perturbation strength. Importantly, this decoupling effect of strong perturbations was consistent across a variety of food-web structures. In Chapter 3, I test these predictions in natural communities using data from the Nutrient Network - a globally distributed grassland experimental system - to examine whether perturbations decouple relationships between components of stability at the global scale. Consistent with theory, I found weaker relationships between stability components in perturbed treatments compared to the unperturbed controls. Natural systems encounter a large variety of perturbations that vary in their spatial extents, durations, frequencies, and intensities. While most models and experiments predicting ecological responses have typically applied static steady- state approaches that focus on a single perturbation event or the mean level of environmental change, few have incorporated environmental stochasticity. Moreover, those that do tend to incorporate it as white noise. In Chapter 4, using food- web modeling I explore how the response and predictability of different stability components are regulated by key characteristics of environmental stochasticity, including its temporal autocorrelation (colour), and the strength of correlations in the responses of species to it. I found that different stability components showed distinct responding patterns to changing temporal autocorrelation of environmental noise. Increasing environmental autocorrelation stabilize communities in some dimensions yet simultaneously destabilize them in others. In contrast, the predictability of stability decreases consistently as the temporal autocorrelation of environmental noise becomes increasingly positive. This finding demonstrates the fundamental role played by environmental stochasticity in determining the dynamics and stability of ecosystems and challenges the… Advisors/Committee Members: Jackson, Andrew.
