57 p, 1.7 MB Industrial and agricultural wastes decreased greenhouse-gas emissions and increased rice grain yield in a subtropical paddy field / Wang, Weiqi (Fujian Normal University. Institute of Geography) ; Zeng, Congsheng (Fujian Normal University. Institute of Geography) ; Sardans i Galobart, Jordi (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Zeng, Dongping (Fujian Normal University.

Institute of Geography) ; Bartrons Vilamala, Mireia (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Reducing the emissions of greenhouse gases (GHG) from paddy fields is crucial both for the sustainability of rice production and mitigation of global climatic warming. The effects of applying industrial and agricultural wastes as fertilizer on the reduction of GHG emissions in cropland areas, however, remain poorly known. [...]

62 p, 1.4 MB Physiological and molecular alterations in plants exposed to high [CO2] under phosphorus stress / Pandey, Renu (Indian Agricultural Research Institute) ; Zinta, Gaurav (University of Antwerp. Department of Biology) ; AbdElgawad, Hamada (University of Antwerp. Department of Biology) ; Ahmad, Altaf (Aligarh Muslim University. Department of Botany) ; Jain, Vanita (Indian Agricultural Research Institute) ; Janssens, Ivan (University of Antwerp. Department of Biology)
Atmospheric [CO2] has increased substantially in recent decades and will continue to do so, whereas the availability of phosphorus (P) is limited and unlikely to increase in the future. P is a non-renewable resource, and it is essential to every form of life. [...]

The present work has explored for the first time acclimation of upper versus lower canopy leaves along an altitudinal gradient. We tested the hypothesis that restrictive climatic conditions associated with high altitudes reduce within-canopy variations of leaf traits. [...]

8 p, 173.7 KB Remote estimation of carbon dioxide uptake by a Mediterranean forest / Garbulsky, Martín Fabio (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Filella, Iolanda (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Papale, Dario (Universidad de Buenos Aires. Faculty of Agronomy)
The estimation of the carbon balance in ecosystems, regions, and the biosphere is currently one of the main concerns in the study of the ecology of global change. Current remote sensing methodologies for estimating gross primary productivity are not satisfactory because they rely too heavily on (i) the availability of climatic data, (ii) the definition of land-use cover, and (iii) the assumptions of the effects of these two factors on the radiation-use efficiency of vegetation (RUE).

13 p, 522.7 KB Twentieth century changes of tree-ring δ13C at the southern range-edge of Fagus sylvatica: increasing water-use efficiency does not avoid the growth decline induced by warming at low altitudes / Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Hunt, Jenny M. (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Ogaya Inurrigarro, Romà (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Jump, Alistair S. (Centre de Recerca Ecològica i d'Aplicacions Forestals)
We aimed to gain knowledge on the changes in intrinsic water use efficiency (iWUE) in response to increasing atmospheric CO2 concentrations and climate change over the last century. We investigated the variation in the iWUE of mature Fagus sylvatica trees located in the higher, central and lower altitudinal forest limits (HFL, CFA and LFL) of one of the southernmost sites of beech distribution in Europe, the Montseny Mountains in Catalonia (northeast Spain), during the last century by analysing the δ13C of their tree rings.

Leaf mineral concentrations of co-occurring Erica arborea, Juniperus communis and Myrtus communis were measured at bimonthly intervals throughout a year in a natural CO2 spring and in a nearby control site with similar soil chemistry in a Mediterranean environment. [...]
