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.

Relationships between the potential production of the greenhouse gases CO2, CH4 and N2O and soil concentrations of C, N and P across 26 paddy fields in southeastern China / Wang, Weiqi (Fujian Normal University. Institute of Geography) ; Sardans i Galobart, Jordi (Centre de Recerca Ecològica i Aplicacions Forestals) ; Wang, Chun (Fujian Normal University.

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.

Global forest carbon uptake due to nitrogen and phosphorus deposition from 1850 to 2100 / Wang, Rong (Laboratoire des Sciences du Climat et de l'Environment) ; Goll, Daniel (Laboratoire des Sciences du Climat et de l'Environment) ; Balkanski, Yves (Laboratoire des Sciences du Climat et de l'Environment) ; Hauglustaine, Didier (Laboratoire des Sciences du Climat et de l'Environment) ; Boucher, Olivier (Université de Paris VII.

Spatial patterns and temporal trends of nitrogen (N) and phosphorus (P) deposition are important for quantifying their impact on forest carbon (C) uptake. In a first step, we modeled historical and future change in the global distributions of the atmospheric deposition of N and P from the dry and wet deposition of aerosols and gases containing N and P.

Physiological adjustments of a Mediterranean shrub to long-term experimental warming and drought treatments / Liu, Daijun (Centre de Recerca Ecològica i Aplicacions Forestals) ; Llusià Benet, Joan (Centre de Recerca Ecològica i Aplicacions Forestals) ; Ogaya Inurrigarro, Romà (Centre de Recerca Ecològica i d'Aplicacions Forestals Forestals) ; Estiarte, Marc (Centre de Recerca Ecològica i Aplicacions Forestals) ; Llorens, Laura (Universitat de Girona.

Key Laboratory of Horticulture Science for Southern Mountainous Regions) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
Warmer temperatures and extended drought in the Mediterranean Basin are becoming increasingly important in determining plant physiological processes and affecting the regional carbon budget. The responses of plant physiological variables such as shoot water potential (Ψ), carbon-assimilation rates (A), stomatal conductance (gs) and intrinsic water-use efficiency (iWUE) to these climatic regimes, however, are not well understood.

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
The application of phosphorus (P) fertilizer to agricultural soils increased by 3. 2 % annually from 2002 to 2010. We quantified in detail the P inputs and outputs of cropland and pasture, and the P fluxes through human and livestock consumers of agricultural products, at global, regional, and national scales from 2002 to 2010.

(Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Manipulative experiments and observations along environmental gradients, the two most common approaches to evaluate the impacts of climate change on nutrient cycling, are generally assumed to produce similar results, but this assumption has rarely been tested. [...]

Tropical insect diversity : evidence of greater host specialization in seed-feeding weevils / Peguero Gutiérrez, Guillermo (Centre de Recerca Ecològica i Aplicacions Forestals) ; Bonal, Raúl (Instituto de Investigación de la Dehesa) ; Sol, Daniel (Centre de Recerca Ecològica i Aplicacions Forestals) ; Muñoz Muñoz, Alberto (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sork, Victoria L. (University of California. Department of Ecology and Evolutionary Biology) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i Aplicacions Forestals)
Host specialization has long been hypothesized to explain the extraordinary diversity of phytophagous insects in the tropics. However, addressing this hypothesis has proved challenging because of the risk of over-looking rare interactions, and hence biasing specialization estimations, and the difficulties to separate the diversity component attributable to insect specialization from that related to host diversity.

Institut für Botanik und Landschaftsökologie) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
Nutrients are essential for plant development, and their availability and stoichiometric ratios can influence the composition of plant communities. We investigated the possibility of the reverse influence: whether the conditions of contrasting species coexistence determine foliar element concentrations and plant stoichiometry, that is, species biogeochemical niche (BN).

21 p, 2.0 MB Long-term fertilization determines different metabolomic profiles and responses in saplings of three rainforest tree species with different adult canopy position / Gargallo-Garriga, Albert (Universitat Autònoma de Barcelona. Servei de Ressonància Magnètica Nuclear) ; Wright, S. Joseph (Smithsonian Tropical Research Institute (Panamà)) ; Sardans i Galobart, Jordi (Centre de Recerca Ecològica i Aplicacions Forestals) ; Pérez-Trujillo, Miriam (Universitat Autònoma de Barcelona. Servei de Ressonància Magnètica Nuclear)
The changes in metabolome provided strong evidence that different nutrients limit different species in different ways. With increasing P availability, the two canopy species shifted their metabolome towards larger investment in protection mechanisms, whereas with increasing N availability, the sub-canopy species increased its primary metabolism.
