Data from: The role of ventromedial prefrontal cortex in reward valuation and future thinking during intertemporal choice

Elisa Ciaramelli & R. Shayna Rosenbaum
The paper investigates the effect of reward magnitude and episodic future thinking (EFT) cues on delay discounting (DD) in 12 patients with lesions to the ventromedial prefrontal cortex (vmPFC patients) and 41 healthy controls. In the Standard condition, participants viewed pairs of monetary amounts (of different magnitude) and were asked to make hypothetical choices between smaller-immediate rewards and larger rewards available after a delay. In the EFT condition, participants imagined personal events to occur at...

Scale-dependent shifts in functional and phylogenetic structure of Mediterranean island plant communities over two centuries

Chunhui Zhang, Marc William Cadotte, Alessandro Chiarucci, Michel Loreau, Charles Willis, Xingfeng Si, Lanping Li & Marcus Cianciaruso
1. Since the Industrial Revolution, the rapid global population and economic expansion has had tremendous impacts on biodiversity across spatial scales, especially for islands. While changes in species richness are easily inferred, the impact of human activity on the underlying community assembly processes has been difficult to ascertain because of lack of long-term community data. 2. Here, we document how the manifestations of plant community assembly have changed over time and space in a Mediterranean...

Data from: Reliable wolf-dog hybrid detection in Europe using a reduced SNP panel developed for non-invasively collected samples

Background: Understanding the processes that lead to hybridization of wolves and dogs is of scientific and management importance, particularly over large geographical scales, as wolves can disperse great distances. However, a method to efficiently detect hybrids in routine wolf monitoring is lacking. Microsatellites offer only limited resolution due to the low number of markers showing distinctive allele frequencies between wolves and dogs. Moreover, calibration across laboratories is time-consuming and costly. In this study, we selected...

Driving cell response through deep learning, a study in simulated 3D cell cultures

Marilisa Cortesi & Emanuele Giordano
Computational simulations are becoming increasingly relevant in biomedical research, providing strategies to reproduce experimental results, improve the resolution of in-vitro experiments, and predict the system’s behavior in untested conditions. The study of how each simulated variable influences measurable outcomes, however, has received little attention. To bridge this gap, we here propose a deep learning framework capable of reliably classify simulated time series data and identify class-defining features. This information will be shown to be useful...

Data from: The role of taxonomic expertise in interpretation of metabarcoding studies

Biancani, Ellen E. Strong, Michael Vecchione, M. G. Harasewych, Karen Reed, Chan Lin, Elise Hartil, Jessica Whelpley, Jamie Blumberg, Kenan Matterson, Niamh E. Redmond, Allison Becker, Michael J. Boyle & Karen J. Osborn
The performance of DNA metabarcoding approaches for characterizing biodiversity can be influenced by multiple factors. Here we used morphological assessment of taxa in zooplankton samples to develop a large barcode database and to assess the congruence of taxonomic identification with metabarcoding under different conditions. We analyzed taxonomic assignment of metabarcoded samples using two genetic markers (COI, 18S V1-2), two types of clustering into molecular operational taxonomic units (OTUs, ZOTUs), and three methods for taxonomic assignment...

The concurrent assessment of agronomic, ecological, and environmental variables enables better choice of agroecological service crop termination management

Xavier Sans
1. Although organic farming was originally promoted as an alternative farming system to address agronomic, environmental, and ecological issues, its conventionalisation has led to an intensification and specialisation of production. In light of this, several studies have questioned the environmental benefits of organic farming as well as its agronomic viability. Thus, there is a need to improve organic vegetable systems to reduce their environmental impact without affecting their productivity. To tackle this challenge, European farmers...

The impact of estimator choice: Disagreement in clustering solutions across K estimators for Bayesian analysis of population genetic structure across a wide range of empirical datasets

Kathryn Stankiewicz, Kate Vasquez Kuntz, Jean-Baptiste Ledoux, Didier Aurelle, Joaquim Garrabou, Yuichi Nakajima, Mikael Dahl, Yuna Zayasu, Sabri Jaziri, Federica Costantini & Iliana Baums
The software program STRUCTURE is one of the most cited tools for determining population structure. To infer the optimal number of clusters from STRUCTURE output, the ΔK method is often applied. However, a recent study relying on simulated microsatellite data suggested that this method has a downward bias in its estimation of K and is sensitive to uneven sampling. If this finding holds for empirical datasets, conclusions about the scale of gene flow may have...

Data from: Land-use legacies influence tree water-use efficiency and nitrogen dynamics in recently established European forests

Rossella Guerrieri, Marta Correia, Irene Martín-Forés, Raquel Alfaro-Sánchez, Joan Pino, Arndt Hampe, Fernando Valladares & Josep Espelta
1. Forest regrowth following farmland (agriculture and pasture) abandonment has been positively associated with a number of processes including the regulation of hydrological cycling, the enhancement of soil functioning, and an increase in forest productivity and carbon (C) sequestration. Although these changes in ecosystem functioning post-farmland abandonment have been observed in multiple locations and studies, the ecophysiological basis underpinning these patterns remains unclear. Here, we examine whether increased forest expansion following pastureland abandonment is associated...

Human impact, climate and dispersal strategies determine plant invasion on islands

Severin D. H. Irl, Andreas H. Schweiger, Manuel J. Steinbauer, Claudine Ah-Peng, José R. Arévalo, Carl Beierkuhnlein, Alessandro Chiarucci, Curtis C. Daehler, José M. Fernández-Palacios, Olivier Flores, Christoph Kueffer, Petr Madera, Rüdiger Otto, Julienne M. I. Schweiger, Dominique Strasberg & Anke Jentsch
Aim: Biological invasions are likely determined by species dispersal strategies as well as environmental characteristics of a recipient region, especially climate and human impact. However, the contribution of climatic factors, human impact and dispersal strategies in driving invasion processes is still controversial and not well embedded in the existing theoretical considerations. Here, we study how climate, species dispersal strategies and human impact determine plant invasion processes on islands distributed in all major oceans in the...

Design of a custom-made device for real-time optical measurement of differential mineral concentrations in 3D scaffolds for bone tissue engineering

Joseph Lovecchio, Valentina Betti, Marilisa Cortesi, Enrico Ravagli, Stefano Severi & Emanuele Giordano
Monitoring bone tissue engineered constructs during their maturation is important to ensure the quality of applied protocols. Several destructive, mainly histochemical, methods are conventionally used to this aim, requiring the sacrifice of the investigated samples. This implies i) to plan several scaffold replicates, ii) expensive and time consuming procedures and iii) to infer the maturity level of a given tissue construct from a cognate replica. To solve these issues, non-destructive techniques such as light spectroscopy-based...

Data from: Facilitation and biodiversity jointly drive mutualistic networks

Gianalberto Losapio, Elizabeth Norton Hasday, Xavier Espadaler, Christoph Germann, Francisco Javier Ortiz-Sánchez, Adrian Pont, Daniele Sommaggio & Christian Schöb
1. Facilitation by nurse plants increases understorey diversity and supports ecological communities. In turn, biodiversity shapes ecological networks and enhances ecosystem functioning. However, whether and how facilitation and increased biodiversity jointly influence community structure and ecosystem functioning remains unclear. 2. We performed a field experiment disentangling the relative contribution of nurse plants and increasing understorey plant diversity in driving pollination interactions. Both the presence of nurse shrubs as well as increased understorey plant diversity increased...
