Diego Fontaneto, Zeyneb Vildan Cakil, Giuseppe Garlasché, Nataliia Iakovenko, Andrea Di Cesare, Ester M. Eckert, Roberto Guidetti, Lina Hamdan, Karel Janko, Dzmitry Lukashanets, Lorena Rebecchi, Stefano Schiaparelli, Tommaso Sforzi, Eva Štefková Kašparová, Alejandro Velasco-Castrillón & Elizabeth Walsh
Aim: The long history of isolation of the Antarctic continent, coupled with the harsh ecological conditions of freezing temperatures could affect the patterns of genetic diversity in the organisms living there. We aim (1) to test whether such pattern can be seen in a mitochondrial marker of bdelloid rotifers, a group of microscopic aquatic and limno-terrestrial animals, and (2) to speculate on the potential mechanisms driving the pattern. Location: focus on Antarctica. Taxon: Rotifera Bdelloidea....

Origin, diversity, and biogeography of Antarctic scale worms (Polychaeta: Polynoidae): a wide-scale barcoding approach

Dominique Cowart, Stefano Schiaparelli, Maria Chiara Alvaro, Matteo Cecchetto, Anne-Sophie Le Port, Didier Jollivet & Stéphane Hourdez
Aim: The Antarctic marine environment hosts diversified and highly endemic benthos owing to its unique geologic and climatic history. Current warming trends have increased the urgency of understanding Antarctic species history to predict how environmental changes will impact ecosystem functioning. Antarctic benthic lineages have traditionally been examined under three hypotheses: 1) high endemism and local radiation, 2) emergence of deep-sea taxa through thermohaline circulation, 3) species migrations across the Polar Front. In this study, we...

Data from: Population genomics meet Lagrangian simulations: oceanographic patterns and long larval duration ensure connectivity among Paracentrotus lividus populations in the Adriatic and Ionian seas

Connectivity between populations is a key factor that influences both their dynamics and the genetic structuring of marine species. In this study, we explored connectivity patterns of a long-dispersing species, the edible common sea urchin Paracentrotus lividus, focusing mainly on the Adriatic-Ionian basins. We applied a multidisciplinary approach integrating population genomics, based on 1122 Single Nucleotide Polymorphisms (SNPs) obtained by 2b-RAD in 275 samples, with Lagrangian simulations performed with a biophysical model of larval dispersal....

Data from: Potential rapid evolution of foot morphology in Italian plethodontid salamanders (Hydromantes strinatii) following the colonization of an artificial cave

Sebastiano Salvidio, Federico Crovetto & Dean C. Adams
How organisms respond to environmental change is a long-standing question in evolutionary biology. Species invading novel habitats provide an opportunity to examine contemporary evolution in action, and decipher the pace of evolutionary change over short time scales. Here we characterized phenotypic evolution in the Italian plethodontid salamander, Hydromantes strinatii following the recent colonization of an artificial cave by a forest floor population. When compared with a nearby and genetically related population in the natural forest...

Data from: Phylogeography of Primula allionii (Primulaceae), a narrow endemic of the Maritime Alps

Gabriele Casazza, Fabrizio Grassi, Giovanni Zecca, Mauro Giorgio Mariotti, Maria Guerrina & Luigi Minuto
Primula allionii is endemic to a tiny area of the Maritime Alps and has one of the narrowest distribution ranges in this hotspot of biodiversity. Phylogeographical patterns in P. allionii were studied using plastid DNA markers and dominantly inherited markers (AFLP and ISSR) to verify any admixture between P. allionii and the sympatric P. marginata and to detect the phylogeographical history of the species. Morphometric measurements of flowers and admixture analysis support the hypothesis that...

Data from: The (in)effectiveness of simulated blur for depth perception in naturalistic images

Guido Maiello, Manuela Chessa, Fabio Solari & Peter J. Bex
We examine depth perception in images of real scenes with naturalistic variation in pictorial depth cues, simulated dioptric blur and binocular disparity. Light field photographs of natural scenes were taken with a Lytro plenoptic camera that simultaneously captures images at up to 12 focal planes. When accommodation at any given plane was simulated, the corresponding defocus blur at other depth planes was extracted from the stack of focal plane images. Depth information from pictorial cues,...

The Atlantic bluefin tuna is a highly migratory species emblematic of the challenges associated with shared fisheries management. In an effort to resolve the species’ stock dynamics, a genome-wide search for spatially informative single nucleotide polymorphisms (SNPs) was undertaken, by way of sequencing reduced representation libraries. An allele frequency approach to SNP discovery was used, combining the data of 555 larvae and young-of-the-year (LYOY) into pools representing major geographical areas and mapping against a newly...

Data from: Genuine cross-frequency coupling networks in human resting-state electrophysiological recordings

Felix Siebenhühner, Sheng H Wang, Gabriele Arnulfo, Lino Nobili, J Matias Palva, Satu Palva & Anna Lampinen
Phase synchronization of neuronal oscillations in specific frequency bands coordinates anatomically distributed neuronal processing and communication. Typically, oscillations and synchronization take place concurrently in many distinct frequencies, which serve separate computational roles in cognitive functions. While within-frequency phase synchronization has been studied extensively, less is known about the mechanisms that govern neuronal processing distributed across frequencies and brain regions. Such integration of processing between frequencies could be achieved via cross-frequency coupling (CFC), either by phase-amplitude...

Combining conservation status and species distribution models for planning assisted colonisation under climate change

Gabriele Casazza, Thomas Abeli, Gianluigi Bacchetta, Davide Dagnino, Giuseppe Fenu, Domenico Gargano, Luigi Minuto, Chiara Montagnani, Simone Orsenigo, Lorenzo Peruzzi, Lucia Varaldo & Graziano Rossi
Effects of climate change are particularly important in the Mediterranean Biodiversity hotspot where rising temperatures and drought are negatively affecting several plant taxa, including endemic species. Assisted Colonisation (AC) represents a useful tool for reducing the effect of climate change on endemic plant species threatened by climate change. We combined SDMs for 188 taxa endemic to Italy with the IUCN red listing range loss threshold under criterion A (30%) to define: a) the number of...

Data from: Magnetic resonance and ultrasound contrast imaging of polymer-shelled microbubbles loaded with iron oxide nanoparticles

Claudia Sciallero, Luca Balbi, Gaio Paradossi & Andrea Trucco
Dual-mode contrast agents (CAs) have great potential for improving diagnostics. However, the effectiveness of CAs is strictly related to both the solution adopted to merge the two agents into a single probe unit, and the ratio between the two agents. In this study, two dual-mode CAs for simultaneous magnetic resonance imaging (MRI) and ultrasound imaging (UI) were assessed. For this purpose, different densities of superparamagnetic iron oxide nanoparticles (SPIONs) were anchored to the external surface...

Data from: Factors associated with first- versus second-generation long-acting antipsychotics prescribed under ordinary clinical practice in Italy

Giovanni Ostuzzi, Maria Angela Mazzi, Samira Terlizzi, Federico Bertolini, Andrea Aguglia, Francesco Bartoli, Paola Bortolaso, Camilla Callegari, Mariarita Caroleo, Giuseppe Carrà, Mariangela Corbo, Armando D'agostino, Chiara Gastaldon, Claudio Lucii, Fabio Magliocco, Giovanni Martinotti, Michela Nosé, Edoardo Giuseppe Ostinelli, Davide Papola, Marco Piccinelli, Alberto Piccoli, Marianna Purgato, Tommaso Tabacchi, Giulia Turrini, Mirella Ruggeri … & Armando D’Agostino
Background. For many years, long-acting intramuscular (LAI) antipsychotics have been prescribed predominantly to chronic and severe patients, as a last resort when other treatments failed. Recently, a broader and earlier use of LAIs, particularly second-generation LAIs, has been emphasized. To date, few studies attempted to frame how this change in prescribing took place in real-world practice. Therefore, this study aimed to describe the clinical features of patients prescribed with LAIs, and to explore possible prescribing...

Data from: The multiple roles of β–diversity help untangle community assembly processes affecting recovery of temperate rocky shores

Mariachiara Chiantore, Simon F. Thrush, Valentina. Asnaghi, Judi E. Hewitt & Valentina Asnaghi
Metacommunity theory highlights the potential of β–diversity as a useful link to empirical research, especially in diverse systems where species exhibit a range of stage-dependent dispersal characteristics. To investigate the importance of different components and scales of β–diversity in community assembly we conducted a large-scale disturbance experiment and compared relative recovery across multiple sites and among plots within sites on the rocky shore. Six sites were spread along 80 km of coastline and, at each...

Data from: Sleep apnea, sleep debt and daytime sleepiness are independently associated with road accidents: a cross-sectional study on truck drivers

Sergio Garbarino, Paolo Durando, Ottavia Guglielmi, Guglielmo Dini, Francesca Bersi, Stefania Fornarino, Alessandra Toletone, Carlo Chiorri & Nicola Magnavita
Background: Recent research has found evidence of an association between motor vehicle accidents (MVAs) or near miss accidents (NMAs), and excessive daytime sleepiness (EDS) or its main medical cause, Obstructive Sleep Apnea (OSA). However, EDS can also be due to non-medical factors, such as sleep debt (SD), which is common among professional truck drivers. On the opposite side, rest breaks and naps are known to protect against accidents. Study objectives: To investigate the association of...

Data from: Work stress and metabolic syndrome in police officers. A prospective study

Sergio Garbarino & Nicola Magnavita
Objective: The aim of this longitudinal study was to evaluate the association between occupational stress and metabolic syndrome (MetS) in a rapid response police unit. Method: Work-related stress was continuously monitored during the 5-year period with both the Demand-Control-Support (DCS) and the Effort-Reward Imbalance (ERI) models. Blood pressure, body mass index (BMI), waist circumference, triglycerides, HDL-cholesterol, and fasting blood glucose were measured at baseline in January 2009, and in January 2014. 234 out of 290...
