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. [...]

66 p, 2.7 MB Factors influencing the foliar elemental composition and stoichiometry in forest trees in Spain / Sardans i Galobart, Jordi (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Alonso, Rocío (Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (Espanya)) ; Carnicer i Cols, Jofre (Universitat de Barcelona. Departament d'Ecologia) ; Fernández-Martínez, Marcos (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; García Vivanco, Marta (Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (Espanya)) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Concentrations of nutrient elements in organisms and in the abiotic environment are key factors influencing ecosystem structure and function. We studied how concentrations and stoichiometries of nitrogen (N), phosphorus (P) and potassium (K) in leaves of forest trees are related to phylogeny and to environmental factors (mean annual precipitation, mean annual temperature, forest type, and nitrogen deposition). [...]

Servei de Ressonància Magnètica Nuclear) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Plants in natural environments are increasingly being subjected to a combination of abiotic stresses, such as drought and warming, in many regions. The effects of each stress and the combination of stresses on the functioning of shoots and roots have been studied extensively, but little is known about the simultaneous metabolome responses of the different organs of the plant to different stresses acting at once.

Institute of Geography) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
We examined the impact of human changes in land use on the concentrations and stoichiometric relationships among soil carbon (C), nitrogen (N), phosphorus (P) and potassium (K) in a Phragmites australis riparian wetland (Minjiang River estuary, China). [...]

44 p, 416.5 KB Potassium : a neglected nutrient in global change / 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: Potassium (K) is the second most abundant nutrient after nitrogen (N) in plant photosynthetic tissues. Thousands of physiological and metabolic studies in recent decades have established the fundamental role of K in plant function, especially in water use efficiency and economy, and yet macroecological studies have mostly overlooked this nutrient. [...]

31 p, 236.4 KB Morphological, biochemical and physiological traits of upper and lower canopy leaves of European beech tend to converge with increasing altitude / Rajsnerová, Petra (Akademie věd České Republiky.

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Urban, Otmar (Akademie věd České Republiky. Centrum výzkumu globální změny)
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. [...]

42 p, 959.0 KB Flood regime affects soil stoichiometry and the distribution of the invasive plants in subtropical estuarine wetlands in China / Wang, Weiqi (Fujian shi fan da xue. Institute of Geography) ; Wang, Chun (Fujian shi fan da xue.

Institute of Geography) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Projections of climate change impacts over the coming decades suggest that rising sea levels will flood coastal wetlands, moving the range of wetlands inland from the current coastline. The intensity of flooding in wetland areas will thus increase, with corresponding impacts on soil properties and coastal ecosystems. [...]

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Global change analyses usually consider biodiversity as a global asset that needs to be preserved. Biodiversity is frequently analysed mainly as a response variable affected by diverse environmental drivers. [...]

37 p, 855.7 KB Shifts in the elemental composition of plants during a very severe drought / Urbina Barreto, Ifigenia (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Sardans i Galobart, Jordi (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Beierkuhnlein, Carl (Universität Bayreuth. Department of Biogeography) ; Jentsch, Anke (Universität Bayreuth. Disturbance Ecology and Vegetation Dynamics) ; Backhausd, Sabrina (Universität Bayreuth. Disturbance Ecology and Vegetation Dynamics) ; Grant, Kerstin (Universität Bayreuth. Disturbance Ecology and Vegetation Dynamics) ; Kreyling, Juergen (Universität Bayreuth. Department of Biogeography) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Diverse plant functions (e. g. , growth, storage, defense and anti-stress mechanisms) use elements disproportionally. We hypothesized that plants growing under different abiotic and biotic conditions would shift their elemental compositions in response to a very severe drought. [...]

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. [...]
