6 p, 1.1 MB Human-driven global nutrient imbalances increase risks to health / Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Sardans i Galobart, Jordi (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Human-induced inputs of nitrogen (N) and phosphorus (P) into the biosphere have reached unprecedented levels, particularly N, leading to an escalating global anthropogenic N:P ratio. This ratio has emerged as a significant driver of environmental change, impacting organisms, ecosystems, and global food security. [...]

48 p, 1.1 MB Plant invasive success associated with higher N-use efficiency and stoichiometric shifts in the soil-plant system in the Minjiang River tidal estuarine wetlands of China / Wang, Weiqi (Fujian Normal University. Institute of Geography) ; Wang, Chun (Fujian Normal University. Institute of Geography) ; Sardans i Galobart, Jordi (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Zeng, Congsheng (Fujian Normal University. Institute of Geography) ; Tong, Chuan (Fujian Normal University. Institute of Geography) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
The tidal estuarine wetlands of China are rich in plant diversity, but several human-driven processes, such as species invasion, can affect the biogeochemical cycles of these ecosystems, and by changing soil conditions can inhibit the regeneration of native vegetation. [...]

38 p, 606.3 KB Ecological stoichiometry of C, N, and P of invasive Phragmites australis and native Cyperus malaccensis species in the Minjiang River tidal estuarine wetlands of China / Wang, Weiqi (Fujian Normal University. Institute of Geography) ; Sardans i Galobart, Jordi (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Wang, Chun (Fujian Normal University. Institute of Geography) ; Zeng, Congsheng (Fujian Normal University) ; Tong, Chuan (Fujian Normal University) ; Asensio, Dolores (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Tidal estuarine wetlands of China are rich in plant diversity, but several global change drivers, such as species invasion, are currently affecting the biogeochemical cycles of these ecosystems. We seasonally analyzed the carbon (C), nitrogen (N), and phosphorus (P) concentrations in litters and soils and in leaves, stems, and roots of the C₃ invasive species Phragmites australis (Cav. [...]

28 p, 1.3 MB Trees increase their P:N ratio with size / Sardans i Galobart, Jordi (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Aim: Phosphorus (P) tends to become limiting in ageing terrestrial ecosystems, and its resorption efficiency is higher than for other elements such as nitrogen (N). We thus hypothesized that trees should store more P than those other elements such as N when tree size increases and that this process should be enhanced in slow-growing late-successional trees. [...]

14 p, 439.0 KB Cyanobacteria distribution and abundance in the Spanish water reservoirs during thermal stratification / Hoyos, C. De (Universidad de Salamanca. Área de Ecología) ; Negro, A. I. (Universidad de Salamanca. Área de Ecología) ; Aldasoro Martín, Juan José (Consejo Superior de Investigaciones Científicas (Espanya). Real Jardín Botànico de Madrid)
A study of the distribution and abundance of Cyanobacteria in 47 Spanish water reservoirs revealed a significant correlation between these algae and total phosphorus in the water. Cyanobacteria distribution was related to the N:P ratio, and they were scarce when the atomic ratio of total inorganic N / total P exceeded 50. [...]
El estudio de la distribución y abundancia de Cianobacterias en 47 embalses españoles reveló una correlación significativa entre estas algas y la concentración de fósforo total en el agua. La distribución de Cianobacterias estuvo relacionada con el cociente N:P, siendo generalmente poco abundantes cuando la relación atómica N inorgánico total / P total fue superior a 50. [...]
