Full textPrésentement, l'activité humaine cause une perte rapide de la biodiversité. Alors que les causes directes de cela sont bien comprises, les causes socio-économiques indirectes ne le sont pas. Le rôle des inégalités économiques dans la prédiction des taux de perte de biodiversité sera examiné à deux échelles différentes dans la présente étude. D'abord, il sera question d'une analyse transnationale de la proportion d'espèces végétales et d'espèces vertébrées qui sont menacées, tel que définit par la liste rouge de l'UICN (Union mondiale pour la nature). Ensuite, le rôle de la couverture terrestre ainsi que celui des variables socio-économiques seront examinés afin de déterminer les tendances de l'abondance des espèces aviennes aux États-Unis. À l'échelle internationale et de façon constante, les inégalités sont un prédicteur. À toute autre qualité égale, la proportion d'espèces menacées est plus élevée dans les pays qui ont de plus grandes inégalités. À la plus petite échelle de l'étude, les variables socio-économiques peuvent expliquer près de 20% de la variation. Cependant, l'inégalité économique n'améliore pas considérablement la prédiction.

Full textThe approach used herein employs both mathematical models and empirical data which represent food webs responding to environmental variability at different hierarchical scales. Within each of these representative food webs, the influence of environmental variability on the stability of the food web is determined using an approach which accounts for the effects of temporal scale. This thesis demonstrates that the stability of simple model food webs (high hierarchical scale) is tightly linked to environmental variability and the temporal scales at which these changes occur dictate which species in the model are most affected. At lower scales of organisation, empirical data indicate that environmental variability generally has a lesser impact on stability and that only certain temporal scales are responsible for this trend. At these temporal scales some species respond differently to environmental variability, negative changes in one species (or group) are offset by positive changes in another - a process known as compensation. These results highlight the importance of both temporal and hierarchical scale in mediating the response of food webs to environmental variability. Ultimately, they will serve to better understand how models and experiments should scale-up from low to high hierarchical and temporal scales.

Across scales ranging from individual blades to river reaches, the interaction between water flow and vegetation has important ecological and engineering implications. At the reach-scale, vegetation is often the largest source of hydraulic resistance. Based on a simple momentum balance, we show that the resistance produced by vegetation depends primarily on the fraction of the channel cross-section blocked by vegetation. For the same blockage, the specific distribution of vegetation also plays a role; a large number of small patches generates more resistance than a single large patch. At the patch-scale, velocity and turbulence levels within the canopy set water renewal and sediment resuspension. We consider both steady currents and wave-induced flows. For steady flows, the flow structure is significantly affected by canopy density. We define sparse and dense canopies based on the relative contribution of turbulent stress and canopy drag to the momentum balance. Within sparse canopies, velocity and turbulent stress remain elevated and the rate of sediment suspension is comparable to that in unvegetated regions. Within dense canopies, velocity and turbulent stress are reduced by canopy drag, and the rate of sediment resuspension is lower. Unlike steady flows, wave-induced oscillatory flows are not significantly damped within vegetated canopies. Further, our laboratory and field measurements show that, despite being driven by a purely oscillatory flow, a mean current in the direction of wave propagation is generated within the canopy. This mean current is forced by a wave stress, similar to the streaming observed in wave boundary layers. At the blade-scale, plant-flow interaction sets posture and drag. Through laboratory experiments and numerical simulations, we show that posture is set by a balance between the hydrodynamic forcing and the restoring forces due to blade stiffness and buoyancy. When the hydrodynamic forcing is small compared to the restoring forces, the blades remain upright in flow and a standard quadratic law predicts the relationship between drag and velocity. When the hydrodynamic forcing exceeds the restoring forces, the blades are pushed over in steady flow, and move with oscillatory flow. For this limit, we develop new scaling laws that link drag with velocity.

Full textL'agriculture moderne a fondamentalement changée le cycle du phosphore (P) d'une façon qui dorénavant pose des défis agronomiques et environnementaux à toutes les échelles. Le P est une ressource non renouvelable qui est d'une importance cruciale à la production alimentaire car c'est essentiel pour les plantes. En même temps, les pertes de P à partir des terres agricoles dans l'eau de ruissellement contribuent à la dégradation de la qualité de l'eau dans le monde entier. J'explore des lacunes importantes au niveau de nos connaissances liées aux changements spatiaux et temporels dans le mouvement du P due à l'activité humaine, leurs causes, et quelques-unes des implications pour la gestion du P dans le sol et de la qualité de l'eau à grande échelle. Premierement, j'ai effectué une analyse à l'échelle globale sur les implications de l'utilisation du P agronomique sur les sols agricoles et sur la distribution actuelle du P dans les sols agricoles. Les résultats spatiaux démontré qu'il y a une disparité entre la quantité de P appliqué aux terres agricoles comme engrais chimiques et comme fumier et le P incorporé dans les récoltes agricoles dans la plus part des régions du monde, mais que l'ampleur de cette disparité varie considérablement entre ces régions. Bien qu'à l'échelle global l'application de P comme engrais (14,2 Tg P/an) et comme fumier (9,6 Tg P/an) collectivement dépasse le P incorporé dans les récoltes agricoles (12,3 Tg P/an), un déficit de P est présent sur près de 30% de la superficie mondiale des terres cultivées. J'ai ensuite effectué une étude approfondie du système agricole des États-Unis et ses partenaires commerciaux afin de comprendre comment la mondialisation exacerbe les changements dans le cycle du P régionale. Le P minéral utilisé aux États-Unis peut être tracée principalement à une accumulation dans les sols agricoles domestiques (28%), les pertes après la récolte (40%), ainsi que la production de bio carburant (10%). Seulement 8% de ce P minéral a été consommée comme nourritures aux Etats-Unis, mais un quart de la demande national d'engrais de P a été alloué à la production d'exportations. Les changements causés par agriculture sur les réservoirs de P dans sols pourraient également avoir des implications écologiques à long terme contenu de la lente vitesse à laquelle le cycle du P a lieu dans certains sols. J'ai mené une méta-analyse exhaustive des études existantes pour comprendre le rôle de l'héritage de présence de culture agricoles sur les réservoirs de P dans des sols après l'abandon agricole à travers le monde. Finalement, j'ai considéré les facteurs anthropologiques déterminants l'accumulation de P dans les lacs en comparaison avec le rôle des caractéristiques biophysiques des bassins versants afin d'aider à l'élaboration de modèles sur le risque d'eutrophisation. J'ai utilisé une approche à multiples facettes statistique pour prédire les concentrations de phosphore total (PT) pour d'un échantillon (> 1000) de lacs dans le monde entier, à partir de cartes d'utilisation des terres mondiale et de données hydrologiques courante. Mondialement les prédictions de PT dans les lacs, à partir de trois approches statistiques uniques, expliquent entre 50% et 79% de la variation observée dans le PT. Collectivement, ce travail illustre comment les modifications agricoles du cycle du P mondiale peuvent être comprit en examinant la gestion du P dans le passé et le présent ainsi que la façon dont cette gestion peut influencer les réserves du P dans les sols et la qualité de l'eau à travers le temps. Une plus grande attention à la variation spatiale dans les deux dimensions de cette problématique et les solutions liés au P, ainsi que leurs dimensions temporelles complexes, sera essentielle pour faire progresser à la fois la science et les politiques nécessaires pour parvenir à une plus grande durabilité dans la gestion du P dans l'agriculture tout en veillant à la santé des écosystèmes aquatiques.
