ERC Synergy grant - 2013 - 610028: Quantify the responses of ecosystems and society in a world increasingly rich in N and C but limited in Phosphorus

El fósforo (P) es un elemento confinado y finito en la tierra, y la perspectiva de que se limite el acceso a sus recursos explotables ya ha desencadenado conflictos geopolíticos. A diferencia de lo que ocurre con el P, en la mayoría de ecosistemas del planeta se está produciendo un rápido aumento de la disponibilidad de carbono (C) y de nitrógeno (N). El cambio inminente en la estequiometría de los elementos disponibles que en resulta no tiene ningún equivalente en la historia de la Tierra y tendrá consecuencias profundas y aún desconocidas para la vida, el sistema terrestre y la sociedad humana. Las desviaciones que se están produciendo en los balances de C:N:P en los ecosistemas por fuerza afectarán la estructura, la función y la diversidad del sistema terrestre. La crisis en el mercado del P podría presionar el sistema alimentario mundial y provocar un efecto ambiental en cadena que abarcaría desde la expansión de tierras agrícolas hasta cambios inducidos por el encarecimiento del P en la gestión de la tierra, lo que agravaría aún más el desequilibrio estequiométrico en los recursos. Sin embargo, los impactos de esta perturbación humana sin precedentes en la estequiometría elemental son todavía un misterio para la ciencia. El proyecto imbalance-P proporcionará una mejora en la comprensión y previsión cuantitativa de estos impactos que permitirán desarrollar una serie de políticas encaminadas a disminuir los riesgos y a mitigar las consecuencias de los desequilibrios estequiométricos. Se emplearán algunos de los modelos de evaluación integrada y del sistema terrestre más importantes de Europa, calibrados utilizando datos de limitación de nutrientes en el ecosistema obtenidos en experimentos de campo. El proyecto establecerá un proceso internacional de base científica en la diplomacia del P.

Metabolomes, as chemical phenotypes of organisms, are likely not only shaped by the environment but also by common ancestry. If this is the case, we expect that closely related species of pines will tend to reach similar metabolomic solutions to the same environmental stressors. [...]

Ongoing spring warming allows the growing season to begin earlier, enhancing carbon uptake in northern ecosystems1, 2, 3. Here we use 34 years of atmospheric CO2 concentration measurements at Barrow, Alaska (BRW, 71° N) to show that the interannual relationship between spring temperature and carbon uptake has recently shifted.

High soil phosphorus levels overrule the potential benefits of organic farming on arbuscular mycorrhizal diversity in northern vineyards / Van Geel, Maarten (KU Leuven Campus Brussel) ; Verbruggen, Erik (University of Antwerp (Bèlgica)) ; De Beenhouwera, Matthias (KU Leuven Campus Brussel) ; van Rennes, Geurt (BeNeVit) ; Lievens, Bart (KU Leuven Campus De Nayer) ; Honnaya, Olivier (KU Leuven Campus Brussel)
Organic farming is a key approach to reconcile food production, biodiversity conservation and environmental sustainability. Due to reduced inputs of agrochemicals, the success of organic farming is heavily dependent on the ecosystem services provided by the soil microbial community, and in particular by arbuscular mycorrhizal fungi (AMF).

Water stored underground in the saturated and subsurface zones below the soil are important sources of water for plants in water-limited ecosystems. The presence of deep-rooted plants worldwide, however, suggests that the use of groundwater is not restricted to arid and seasonally dry ecosystems. [...]

Dolores (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
Paddy fields are a major global anthropogenic source of greenhouse gases. China has the second largest area under rice cultivation, so determining the relationships between the emission of greenhouse gases and soil carbon content, nutrient availabilities and concentrations and physical properties is crucial for minimizing the climatic impacts of rice agriculture.
