Human pressure mapping is important for understanding humanity's role in shaping Earth’s patterns and processes. Our ability to map this influence has evolved, thanks to powerful computing, earth observing satellites, and new bottom-up census and crowd-sourced data. Here, we provide the latest temporally inter-comparable maps of the terrestrial human footprint, and assessment of change in human pressure at global, biome, and ecoregional scales. In 2013, 42% of terrestrial Earth could be considered relatively free of...

Data from: Tetra-EU 1.0: a species-level trophic meta-web of European tetrapods

Luigi Maiorano, Alessandro Montemaggiori, Gentile Francesco Ficetola, Louise O'Connor & Wilfried Thuiller
Motivation Documenting potential interactions between species represents a major step to understand and predict the spatial and temporal structure of multi-trophic communities and their functioning. The metaweb concept summarises the potential trophic (and non-trophic) interactions in a given species-pool. As such, it generalises the regional species-pool of community ecology by incorporating the potential relationships between species from different trophic levels along with their functional characteristics. However, while this concept is theoretically very attractive, it has...

The origins of the neural basis of peripersonal space in human infancy - Datasets

Giulia Orioli, Irene Parisi, José van Velzen & Andrew Bremner
This Dataset contains the pre-processed EEG recordings gathered from 20 4-month-old and 20 8-month-old participants who took part in a research study aimed at investigating the origins of the neural basis of peripersonal space in human infancy. The Dataset includes only the recordings of the participants included in the final sample and each file contains only the good, artefact-free trials completed by each participant. For each participant, 2 files are available. The first one (in...

Mathematica codes for: Cosmological singularity as an informational seed for Everything

Sergey Cherkas & Vladimir Kalashnikov
The Mathematica notebooks calculate mean values of the energy density of the quantum fields under curved background. The background of the uniform isotropic expanding universe is implied. The notebooks densitySec2.nb and densitySec3.nb are related to the methods described in the second and third sections of the paper respectively. These notebooks give the same results.

From alpha to beta functional and phylogenetic redundancy

Carlo Ricotta, Fabien Laroche, Laszlo Szeidl & Sandrine Pavoine
1. Plot-level redundancy or alpha redundancy is usually defined as the fraction of species diversity not expressed by functional or phylogenetic diversity. Redundancy is zero when all species in one plot are maximally dissimilar from each other. By contrast, redundancy tends to its maximum if the functional or phylogenetic differences between species tend to be minimal. 2. To explore the ecological drivers of community assembly, ecologists also use dissimilarity measures between pairs of plots (a...

Large carnivore expansion in Europe is associated with human population density and land cover changes

Marta Cimatti, Nathan Ranc, Ana Ana Benítez-López, Luigi Maiorano, Luigi Boitani, Francesca Cagnacci, Mirza Čengić, Paolo Ciucci, Mark Huijbregts, Miha Krofel, José López Bao, Nuria Selva, Henrik Andren, Carlos Bautista, Duško Cirovic, Heather Hemmingmoore, Ilka Reinhardt, Miha Marenče, Yorgos Mertzanis, Luca Pedrotti, Igor Trbojević, Andreas Zetterberg, Tomasz Zwijacz-Kozica & Luca Santini
Aim: The recent recovery of large carnivores in Europe has been explained as resulting from a decrease in human persecution driven by widespread rural land abandonment, paralleled by forest cover increase and the consequent increase in availability of shelter and prey. We investigated whether land cover and human population density changes are related to the relative probability of occurrence of three European large carnivores: the grey wolf (Canis lupus), the Eurasian lynx (Lynx lynx) and...

Data from: Methane emission offsets carbon dioxide uptake in a small productive lake

Dominic Vachon, Timon Langenegger, Daphne Donis, Stan E. Beaubien & Daniel McGinnis
Here we investigate the importance of net CH4 production and emissions in the carbon (C) budget of a small eutrophic lake by monitoring CH4, CO2 and O2 during two consecutive years. During the study period, the lake was mostly a net emitter of both CH4 and CO2, while having a net autotrophic metabolism. The analyses suggest that during the whole study period 29 ± 23 % of C produced by net ecosystem production was ultimately...

Reconstructing hotspots of genetic diversity from glacial refugia and subsequent dispersal in Italian common toads (Bufo bufo)

Andrea Chiocchio, Jan Arntzen, Iñigo Martínez-Solano, Wouter De Vries, Roberta Bisconti, Alice Pezzarossa, Luigi Maiorano & Daniele Canestrelli
Genetic diversity feeds the evolutionary process and allows populations to adapt to environmental changes. However, we still lack a thorough understanding of why hotspots of genetic diversity are so 'hot'. Here, we analysed the relative contribution of bioclimatic stability and genetic admixture between divergent lineages in shaping spatial patterns of genetic diversity in the common toad Bufo bufo along the Italian peninsula. We combined population genetic, phylogeographic and species distribution modelling (SDM) approaches to map...

Data and R code for: An experimental approach to assessing the impact of ecosystem engineers on biodiversity and ecosystem functions

Gianalberto Losapio, Bernhard Schmid, Jordi Bascompte, Richard Michalet, Pierfilippo Cerretti, Christoph Germann, Jean-Paul Haenni, Rainer Neumeyer, Francisco Javier Ortiz-Sánchez, Adrian C Pont, Pascal Rousse, Jürg Schmid, Daniele Sommaggio & Christian Schöb
Plants acting as ecosystem engineers create habitats and facilitate biodiversity maintenance within plant communities. Furthermore, biodiversity research has demonstrated that plant diversity enhances the productivity and functioning of ecosystems. However, these two fields of research developed in parallel and independent from one another, with the consequence that little is known about the role of ecosystem engineers in the relationship between biodiversity and ecosystem functioning across trophic levels. Here, we present an experimental framework to study...

Proactive conservation to prevent habitat losses to agricultural expansion

David Williams, Michael Clark, Graeme M. Buchanan, G. Francesco Ficetola, Carlo Rondinini & David Tilman
The projected loss of millions of square kilometres of natural ecosystems to meet future demand for food, animal feed, fibre, and bioenergy crops is likely to massively escalate threats to biodiversity. Reducing these threats requires a detailed knowledge of how and where they are likely to be most severe. We developed a geographically explicit model of future agricultural land clearance based on observed historic changes and combine the outputs with species-specific habitat preferences for 19,859...

Data from: A method for mapping morphological convergence on three-dimensional digital models: the case of the mammalian saber-tooth

Pasquale Raia, Marina Melchionna, Antonio Profico, Silvia Castiglione, Carmela Serio, Alessandro Mondanaro, Maria Modafferi, Davide Tamagnini, Luigi Maiorano, Pasquale Raia, Stephen Wroe, Lawrence Witmer & Gabriele Sansalone
Morphological convergence can be assessed through a variety of statistical methods. None of the methods proposed to date enable the visualization of convergence. All are based on the assumption that the phenotypes either converge, or do not. However, between species, morphologically similar regions of a larger structure may behave differently. Previous approaches do not identify these regions within the larger structures or quantify the degree to which they may contribute to overall convergence. Here we...
