Data from: Pine afforestation decreases the long-term performance of understory shrubs in a semiarid Mediterranean ecosystem: a stable isotope approach.

Cristina Moreno-Gutiérrez, Giovanna Battipaglia, Paolo Cherubini, Antonio Delgado Huertas & José Ignacio Querejeta
1. Plant–plant interactions shape the structure and composition of plant communities, but shifts in interaction outcomes might occur in the face of ongoing climate change. 2. We assessed the influence of Pinus halepensis plantations on the long-term ecophysiological performance of understorey vegetation, by conducting a retrospective comparison (1989–2007) of growth-ring widths, δ13C and δ18O between Rhamnus lycioides shrubs from two contrasting vegetation types: P. halepensis plantations vs. open woodlands. We also measured the leaf δ13C,...

Data from: Altered leaf litter quality exacerbates the negative impact of climate change on decomposition

Iván Prieto, Maria Almagro, Felipe Bastida & José Ignacio Querejeta
1.Leaf litter decomposition is a key component of global biogeochemical cycles that influences soil carbon storage, nutrient availability and plant productivity. Ongoing climate change will lead to warmer and drier conditions in many dryland regions, potentially affecting litter decomposition and nutrient dynamics. Climate change effects can be direct and/or indirect, e.g. through changes in litter quality, yet their relative importance on litter decomposition remains unclear. 2. We conducted a manipulative study in a semiarid shrubland...

Data from: The role of nutritional impairment in carbon-water balance of silver fir drought-induced dieback

Ester González De Andrés, Antonio Gazol, José Ignacio Querejeta, José M. Igual, Michele Colangelo, Raúl Sánchez-Salguero, Juan Carlos Linares & J. Julio Camarero
Rear-edge populations at the xeric distribution limit of tree species are particularly vulnerable to forest dieback triggered by drought. This is the case of silver fir (Abies alba) forests located in the southwestern of Europe. While silver fir drought-induced dieback patterns have been previously explored, information on the role played by nutritional impairment is lacking despite its potential interactions with tree carbon-water balances. We performed a comparative analysis of radial growth, intrinsic water-use efficiency (iWUE),...

Data from: Leaf carbon and oxygen isotopes are coordinated with the leaf economics spectrum in Mediterranean rangeland species

Iván Prieto, José I. Querejeta, Jules Segrestin, Florence Volaire & Catherine Roumet
The leaf economics spectrum (LES) describes covariation of traits relevant to carbon and nutrient economics across plant species, but much less is known about the relationship between the LES and leaf water economy. We propose an approach combining the measurement of two leaf traits related to water use economy, leaf carbon (δ13C) and oxygen (δ18O) isotopic composition, and the measurement of leaf morphological and nutrient traits to investigate the link between leaf carbon and nutrient...

Nanobiofertilizants of B and Fe

Micaela Carvajal, Juan J. Rios, Lucia Yepes-Molina & Alberto Martinez-Alonso
Nanofertilization is postulated as a new technology to deal with the environmental problems caused by the intensive use of traditional fertilizers. One of the aims of this new technology is to improve foliar fertilization, which has many environmental advantages but currently there are numerous factors that limit its efficiency. In this research, the objective was to study the potential of membrane vesicles derived from plant material as nanofertilizers of iron (Fe) and boron (B) for...

Large-scale drivers of relationships between soil microbial properties and organic carbon across Europe

Linnea C Smith, Alberto Orgiazzi, Nico Eisenhauer, Simone Cesarz, Alfred Lochner, Arwyn Jones, Felipe Bastida, Guillaume Patoine, Thomas Reitz, François Buscot, Matthias Rillig, Anna Heintz-Buschart, Anika Lehmann & Carlos Guerra
The aim of this study was to quantify direct and indirect relationships between soil microbial community properties (potential basal respiration, microbial biomass) and abiotic factors (soil, climate) in three major land-cover types. Location: Europe Time period: 2018 Major taxa studied: Microbial community (fungi and bacteria) We collected 881 soil samples from across Europe in the framework of the Land Use/Land Cover Area Frame Survey (LUCAS). We measured potential soil basal respiration at 20ºC and microbial...

Phenotypic and Genetic data for \"Evolution of fruit and seed traits during almond naturalization\"

Rafael Rubio De Casas, Andres Barea Marquez, Francisco Ocaña-Calahorro, Rodrigo Balaguer-Romano, José María Gómez, Eugene W. Schupp, Raquel Sanchez-Perez, Jesus Guillamon & Joanna Zhang
1- Cultivated plant species often naturalize and enter wild communities in a process known as feralization. To successfully feralize, crops must overcome ecological barriers and may undergo selection on certain traits, diverging phenotypically and genetically from their crop ancestors. In spite of the agronomic and ecological relevance of crop feralization, the eco-evolutionary dynamics driving it remain understudied. 2- In this paper, we evaluated phenotypic and genotypic differentiation in fruit and seed traits during the naturalization...
