26 p, 1.6 MB Abrupt changes in the composition and function of fungal communities along an environmental gradient in the High Arctic / Grau Fernández, Oriol (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Geml, József (Naturalis Biodiversity Center) ; Pérez-Haase, Aaron (Universitat de Barcelona. Departament de Biologia Evolutiva, Ecologia i Ciències Ambientals) ; Ninot Sugrañes, Josep M. (Universitat de Barcelona.

(Naturalis Biodiversity Center) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Fungi play a key role in soil-plant interactions, nutrient cycling and carbon flow and are essential for the functioning of arctic terrestrial ecosystems. Some studies have shown that the composition of fungal communities is highly sensitive to variations in environmental conditions, but little is known about how the conditions control the role of fungal communities (i.

College of Urban and Environmental Sciences) ; Huang, Ye (Laboratoire des Sciences du Climat et de l'Environment) ; Tao, Shu (Beijing da xue. College of Urban and Environmental Sciences)
Spatial patterns and temporal trends of nitrogen (N) and phosphorus (P) deposition are important for quantifying their impact on forest carbon (C) uptake. In a first step, we modeled historical and future change in the global distributions of the atmospheric deposition of N and P from the dry and wet deposition of aerosols and gases containing N and P.

38 p, 1.6 MB Shift in community structure mainly by the losses of herbs in long-term warming and drought experiments and natural extreme droughts in an early-successional Mediterranean shrubland / Liu, Daijun (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Estiarte, Marc (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Ogaya Inurrigarro, Romà (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Yang, Xiaohong (Xi nan da xue (China). Key Laboratory of Horticulture Science for Southern Mountainous Regions) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Global warming and recurring drought are expected to accelerate water limitation for plant communities in semiarid Mediterranean ecosystems and produce directional shifts in structure and composition that are not easily detected, and supporting evidence is scarce. [...]

34 p, 1.8 MB Physiological adjustments of a Mediterranean shrub to long-term experimental warming and drought treatments / Liu, Daijun (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Llusià Benet, Joan (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Ogaya Inurrigarro, Romà (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Estiarte, Marc (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Llorens, Laura (Universitat de Girona. Departament de Ciències Ambientals) ; Yang, Xiaohong (Xi nan da xue (China). Key Laboratory of Horticulture Science for Southern Mountainous Regions) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Warmer temperatures and extended drought in the Mediterranean Basin are becoming increasingly important in determining plant physiological processes and affecting the regional carbon budget. The responses of plant physiological variables such as shoot water potential (Ψ), carbon-assimilation rates (A), stomatal conductance (gs) and intrinsic water-use efficiency (iWUE) to these climatic regimes, however, are not well understood.

45 p, 1.5 MB Global and regional phosphorus budgets in agricultural systems and their implications for phosphorus-use efficiency / Lun, Fein (China Agricultural University. College of Resources and Environment Sciences) ; Liu, Jungo (South University of Science and Technology of China. School of Environmental Science and Engineering) ; Ciais, Philippe (Centre d'Etudes Orme des Merisiers) ; Nesme, Thomas (Université de Bordeaux.

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
The application of phosphorus (P) fertilizer to agricultural soils increased by 3. 2 % annually from 2002 to 2010. We quantified in detail the P inputs and outputs of cropland and pasture, and the P fluxes through human and livestock consumers of agricultural products, at global, regional, and national scales from 2002 to 2010.

19 p, 4.3 MB Experimental and observational studies find contrasting responses of soil nutrients to climate change / Yuan, Zhiyou ; Jiao, Feng ; Shi, X. R. ; 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)
Manipulative experiments and observations along environmental gradients, the two most common approaches to evaluate the impacts of climate change on nutrient cycling, are generally assumed to produce similar results, but this assumption has rarely been tested. [...]

14 p, 3.0 MB Plant community composition affects the species biogeochemical niche / Urbina Barreto, Ifigenia (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Sardans i Galobart, Jordi (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Grau Fernández, Oriol (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Beierkuhnlein, Carl (Universität Bayreuth.

Institut für Botanik und Landschaftsökologie) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Nutrients are essential for plant development, and their availability and stoichiometric ratios can influence the composition of plant communities. We investigated the possibility of the reverse influence: whether the conditions of contrasting species coexistence determine foliar element concentrations and plant stoichiometry, that is, species biogeochemical niche (BN).

13 p, 3.2 MB Global patterns of phosphatase activity in natural soils / Margalef, Olga (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Sardans i Galobart, Jordi (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Fernández-Martínez, Marcos (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Soil phosphatase levels strongly control the biotic pathways of phosphorus (P), an essential element for life, which is often limiting in terrestrial ecosystems. We investigated the influence of climatic and soil traits on phosphatase activity in terrestrial systems using metadata analysis from published studies. [...]

In December 2015 in Paris, leaders committed to achieve global, net decarbonization of human activities before 2100. This achievement would halt and even reverse anthropogenic climate change through the net removal of carbon from the atmosphere. [...]
