All ICOS stations follow the ICOS Atmospheric Station specification V1.3 (https://www.icos-ri.eu/fetch/ba12290c-3714-4dd5-a9f0-c431b9900ad1;1.0) and are certified as ICOS atmospheric stations Class I or II. Data processing has been performed as described in Hazan et al., 2016 (doi:10.5194/amt-9-4719-2016).

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...

Data from: NOS: a software suite to compute node overlap and segregation in ecological networks

Giovanni Strona, Thomas Joseph Matthews, Susanne Kortsch & Joseph A. Veech
Investigating the structure of ecological networks can help unravel the mechanisms promoting and maintaining biodiversity. Recently, Strona and Veech (10.1111/2041-210X.12395) introduced a new metric (Ɲ ̅, pronounced ‘nos’), that allows assessment of structural patterns in networks ranging from complete node segregation to perfect nestedness, and that also provides a visual and quantitative assessment of the degree of network modularity. The Ɲ ̅ metric permits testing of a wide range of hypotheses regarding the tendency for...

Data from: Predicting the spread of an invasive tree pest: the pine wood nematode in Southern Europe

Begoña De La Fuente, Santiago Saura, Pieter S.A. Beck & Pieter S. A. Beck
1. Invasive tree pests are increasingly threatening forest ecosystems. Understanding and controlling their spread presents a major challenge for managers, researchers, and policy makers. In 1999, the pine wood nematode Bursaphelenchus xylophilus, causal agent of pine wilt disease and native to North America, was first detected in Europe, more precisely in south western Portugal. Since then, it has spread to more than 30% of the country, producing large-scale damages in Portuguese forests. 2. We applied...

Data from: Range-wide population structure of European sea bass Dicentrarchus labrax

Erika L. Souche, Bart Hellemans, Massimiliano Babbucci, Eoin MacAoidh, Bruno Guinand, Luca Bargelloni, Dimitry Alexandrovich Chistiakov, Tomaso Patarnello, François Bonhomme, Jann T. Martinsohn & Filip A. M. Volckaert
The euryhaline European sea bass Dicentrarchus labrax L., inhabiting the coasts of the eastern Atlantic Ocean and Mediterranean Sea, has had many opportunities for differentiation throughout its large natural range. However, evidence for this has been incompletely documented geographically and with an insufficient number of markers. Therefore, its full range was sampled at 22 sites and individuals were genotyped with a suite of mapped markers, including 14 microsatellite loci (N = 536) and 46 neutral...

Data from: Fire evolution in the radioactive forests of Ukraine and Belarus: future risks for the population and the environment

This paper analyzes the current and future status of forests in Ukraine and Belarus that were contaminated after the nuclear disaster in 1986. Using several models, together with remote sensing data and observations, we studied how climate change in these forests may affect fire regimes. We investigated the possibility of 137Cs displacement over Europe by studying previous fire events, and examined three fire scenarios that depended on different emission altitudes of 137Cs, assuming that 10%...

Data from: Regional environmental pressure influences population differentiation in turbot (Scophthalmus maximus)

S. G. Vandamme, G. E. Maes, J. A. M. Raeymaekers, K. Cottenie, A. K. Imsland, B. Hellemans, G. Lacroix, E. Mac Aoidh, J. T. Martinsohn, P. Martínez, J. Robbens, R. Vilas & F. A. M. Volckaert
Unravelling the factors shaping the genetic structure of mobile marine species is challenging due to the high potential for gene flow. However, genetic inference can be greatly enhanced by increasing the genomic, geographic or environmental resolution of population genetic studies. Here we investigated the population structure of turbot (Scophthalmus maximus) by screening 17 random and gene-linked markers in 999 individuals at 290 geographical locations throughout the Northeast Atlantic Ocean. A seascape genetics approach with the...

Data from: Transition from fractional to classical Stokes-Einstein behaviour in simple fluids

Diego Coglitore, Stuart P. Edwardson, Peter Macko, Eann A. Patterson & Maurice Whelan
An optical technique for tracking single particles has been used to evaluate the particle diameter at which diffusion transitions from molecular behaviour described by the fractional Stokes-Einstein relationship to particle behaviour described by the classical Stokes-Einstein relationship. The results confirm a prior prediction from molecular dynamic simulations that there is a particle size at which transition occurs and show it is inversely dependent on concentration and viscosity but independent of particle density. For concentrations in...

Data from: Settling dynamics of nanoparticles in simple and biological media

Francesco Giorgi, Peter Macko, Jude Curran, Andrew Worth, Maurice Whelan & Eann Patterson
The biological response of organisms exposed to nanoparticles is often studied in vitro using adherent monolayers of cultured cells. In order to derive accurate concentration-response relationships, it is important to determine the local concentration of nanoparticles to which the cells are actually exposed rather than the nominal concentration of nanoparticles in the cell-culture medium. In this study, the sedimentation–diffusion process of different sized and charged gold nanoparticles has been investigated in vitro by evaluating their...
