The response of stocks of C, N, and P to plant invasion in the coastal wetlands of China.
Weiqi Wang,Jordi Sardans,Chun Wang,Congsheng Zeng,Chuan Tong,Guixiang Chen,Jiafang Huang,Haoran Pan,Guille Peguero,Helena Vallicrosa,Josep Peñuelas +10 more
TL;DR: Investigation of the relationships between the different stocks of soil organic carbon, and total C, N, and P pools in the plant-soil system from eight different wetland areas across the South-East coast of China showed that a future advance in the native mangrove replacement by Spartina alterniflora could constitute a serious environmental problem.
Journal ArticleDOI
Increasing atmospheric CO2 concentrations correlate with declining nutritional status of European forests.
Josep Peñuelas,Marcos Fernández-Martínez,Helena Vallicrosa,Joan Maspons,Paolo Zuccarini,Jofre Carnicer,Tanja G. M. Sanders,Inken Krüger,Michael Obersteiner,Ivan A. Janssens,Philippe Ciais,Jordi Sardans +11 more
TL;DR: It is found that foliar concentrations of N, P, K, S and Mg have decreased in central and southern Europe, with implications for forest ecosystems.
Journal ArticleDOI
Empirical support for the biogeochemical niche hypothesis in forest trees.
Jordi Sardans,Helena Vallicrosa,Paolo Zuccarini,Gerard Farré-Armengol,Marcos Fernández-Martínez,Guille Peguero,Albert Gargallo-Garriga,Philippe Ciais,Ivan A. Janssens,Michael Obersteiner,Andreas Richter,Josep Peñuelas +11 more
TL;DR: In this article, the authors investigated the relationship between the foliar elemental compositions (elementomes) of trees at a global scale with phylogeny, climate, N deposition and soil traits.
Journal ArticleDOI
Nitrogen reduction processes in paddy soils across climatic gradients: Key controlling factors and environmental implications
Xiaofei Li,Jordi Sardans,Albert Gargallo-Garriga,Dolores Asensio,Helena Vallicrosa,Josep Peñuelas +5 more
TL;DR: In this article, the potential rates of denitrification, anaerobic ammonium oxidation (anammox) and dissimilatory nitrate reduction to ammonium (DNRA) were investigated in paddy soils from temperate to tropical climates.
Journal ArticleDOI
Global distribution and drivers of forest biome foliar nitrogen to phosphorus ratios (N:P)
TL;DR: In this paper , a global map of foliar nitrogen-to-phosphorus (N:P) ratios across ecosystems was created to identify global drivers of woody vegetation N:P ratios and explore the role of genetic legacy.
