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.

7 p, 804.3 KB Measuring temporal patterns in ecology : The case of mast seeding / Fernández-Martínez, Marcos (University of Antwerp. Department of Biology (Belgium)) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Properly assessing temporal patterns is a central issue in ecology in order to understand ecosystem processes and their mechanisms. Mast seeding has traditionally been described as a reproductive behavior consisting of highly variable and synchronized reproductive events. [...]

Acid phosphatase produced by plants and microbes plays a fundamental role in the recycling of soil phosphorus (P). A quantification of the spatial variation in potential acid phosphatase activity (AP) on large spatial scales and its drivers can help to reduce the uncertainty in our understanding of bio-availability of soil P.

The soil quality index (SQI) is based on several key indicators and is used to assess soil quality. More than 250,000 ha of walnut saplings (Juglans regia L. ) were planted in previous cropland areas in the Sichuan Basin, China, using a range of soil cover types that may affect soil quality with effects that are unclear.

Potassium, mostly as a cation (K+), together with calcium (Ca2+) are the most abundant inorganic chemicals in plant cellular media, but they are rarely discussed. K+ is not a component of molecular or macromolecular plant structures, thus it is more difficult to link it to concrete metabolic pathways than nitrogen or phosphorus. [...]

The high spatial resolution and revisit time of Sentinel-2A/B tandem satellites allow a potentially improved retrieval of land surface phenology (LSP). The biome and regional characteristics, however, greatly constrain the design of the LSP algorithms. [...]

High-quality retrieval of land surface phenology (LSP) is increasingly important for understanding the effects of climate change on ecosystem function and biosphere-atmosphere interactions. We analyzed four state-of-the-art phenology methods: threshold, logistic-function, moving-average and first derivative based approaches, and retrieved LSP in the North Hemisphere for the period 1999-2017 from Copernicus Global Land Service (CGLS) SPOT-VEGETATION and PROBA-V leaf area index (LAI) 1 km V2.

The emissions of isoprenoids, a kind of biogenic volatile organic compounds (BVOCs), from soils is not well characterized. We quantified the exchange of isoprenoids between soil with litter and atmosphere along a horizontal gradient from the trunks of the trees, in a Mediterranean Pinus pinea plantation with dry and green needle litter to open herbaceous turf during mornings at mid-summer.
