Data from: Improving the early detection of alien wood-boring beetles in ports and surrounding forests

Davide Rassati, Massimo Faccoli, Edoardo Petrucco Toffolo, Andrea Battisti & Lorenzo Marini
1. International ports are generally considered the most likely points of entry for alien wood-boring beetles. A better understanding of the factors affecting their arrival and establishment at ports and their surrounding areas is of utmost importance to improve the efficacy and the cost-effectiveness of early detection programmes. Our work aimed at understanding how port size and the characteristics of the landscape surrounding the port, in terms of forest cover and forest composition, influence the...

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

Marta Paterno, Marcello Schiavina, Giorgio Aglieri, Jamila Ben Souissi, Elisa Boscari, Renato Casagrandi, Aurore Chassanite, Mariachiara Chiantore, Leonardo Congiu, Giuseppe Guarnieri, Claudia Kruschel, Vesna Macic, Ilaria Anna Maria Marino, Chiara Papetti, Tomaso Patarnello, Lorenzo Zane & Paco Melià
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: Possible glimpses into early speciation: the effect of ovarian fluid on sperm velocity accords with post-copulatory isolation between two guppy populations

Alessandro Devigili, John L Fitzpatrick, Clelia Gasparini, Indar W Ramnarine, Andrea Pilastro & Jonathan P Evans
Identifying mechanisms of reproductive isolation is key to understanding speciation. Among the putative mechanisms underlying reproductive isolation, sperm-female interactions (postmating-prezygotic barriers) are arguably the hardest to identify, not least because these are likely to operate at the cellular or molecular level. Yet sperm-female interactions offer great potential to prevent the transfer of genetic information between different populations at the initial stages of speciation. Here we provide a preliminary test for the presence of a putative...

Data from: Prenatal exposure to predation affects predator recognition learning via lateralization plasticity

Tyrone Lucon-Xiccato, Douglas P. Chivers, Matthew D. Mitchell & Maud C. O. Ferrari
Prey with cerebral lateralization often shows a bias in escape direction and asymmetrical use of eyes for scanning. Such asymmetries are likely to cause ecological disadvantages when, for example, predators attack from the side in which the prey is more susceptible. However, lateralized individuals are diffuse in many species and, paradoxically, their frequency increases via developmental plasticity in environments with high-predation risk. Using wood frog tadpoles, Lithobates sylvaticus, we tested the hypothesis that cerebral lateralization...

Data from: Discrimination reversal learning reveals greater female behavioural flexibility in guppies

Tyrone Lucon-Xiccato & Angelo Bisazza
Behavioural flexibility allows an animal to adapt its behaviour in response to changes in the environment. Research conducted in primates, rodents and domestic fowl suggests greater behavioural persistence and reduced behavioural flexibility in males. We investigated sex differences in behavioural flexibility in fish by comparing male and female guppies (Poecilia reticulata) in a reversal learning task. Fish were first trained on a colour discrimination, which was learned equally rapidly by males and females. However, once...

Data from: Soil management shapes ecosystem service provision and trade-offs in agricultural landscapes

Giovanni Tamburini, Serena De Simone, Maurizia Sigura, Francesco Boscutti & Lorenzo Marini
Agroecosystems are principally managed to maximize food provisioning even if they receive a large array of supporting and regulating ecosystem services (ESs). Hence, comprehensive studies investigating the effects of local management and landscape composition on the provision of and trade-offs between multiple ESs are urgently needed. We explored the effects of conservation tillage, nitrogen fertilization and landscape composition on six ESs (crop production, disease control, soil fertility, water quality regulation, weed and pest control) in...

Immunological changes in nestlings growing under predation risk

Gianluca Roncalli, Manuel Soler, B. Irene Tieleman, Maaike A. Versteegh, Francisco Ruiz–Raya, Elisa Colombo, Mercedes Gómez Sambla & Juan Diego Ibáñez–Álamo
Predation is one of the most relevant selective forces in nature. However, the physiological mechanisms behind anti‐predator strategies have been overlooked, despite their importance to understand predator‐prey interactions. In this context, the immune system could be especially revealing due to its relationship with other critical functions and its ability to enhance prey's probabilities of survival to a predator's attack. Developing organisms (e.g. nestlings) are excellent models to study this topic because they suffer a high...

Data from: Hydrologic controls on river network connectivity

Silvia Garbin, Elisa Alessi Celegon, Pietro Fanton & Gianluca Botter
This study proposes a probabilistic approach for the quantitative assessment of reach- and network-scale hydrological connectivity as dictated by river flow space-time variability. Spatial dynamics of daily streamflows are estimated based on climatic and morphological features of the contributing catchment, integrating a physically based approach that accounts for the stochasticity of rainfall with a water balance framework and a geomorphic recession flow analysis. Ecologically meaningful minimum stage thresholds are used to evaluate the connectivity of...

Seasonal time constraints shape life history, physiology and behaviour independently, and decouple a behavioural syndrome in a damselfly

Nedim Tüzün, Beste Başak Savaşçı & Robby Stoks
The integration of traits into 'syndromes' has been suggested as a useful framework to advance insights in trait responses to environmental stressors. Yet, how stressors shape the consistency (‘repeatability’) of traits and their covariation at the individual level remains debated. We studied how seasonal time constraints shape trait repeatability and integration of life-history, behavioural, and physiological traits along a fast-slow continuum, using the ‘pace-of-life syndrome’ as a framework. We manipulated the photoperiod during the larval...

Caterpillar polarisation vision: Histological methods and Rcodes for behavioural analyses

Mizuki Uemura, Andrej Meglič, Myron Zalucki, Andrea Battisti & Gregor Belušič
Processionary caterpillars of Thaumetopoea pityocampa (in Europe) and Ochrogaster lunifer (in Australia) (Lepidoptera: Notodontidae) form single files of larvae crawling head-to-tail when moving to feeding and pupation sites. We investigated if the processions are guided by polarisation vision. The heading orientation of processions could be manipulated with linear polarising filters held above the leading caterpillar. Exposure to changes in the angle of polarisation around the caterpillar resulted in orthogonal changes in heading angles. Anatomical analysis...

Data from: Crop pests and predators exhibit inconsistent responses to surrounding landscape composition

Daniel S. Karp, Rebecca Chaplin-Kramer, Timothy D. Meehan, Emily A. Martin, Fabrice DeClerck, Heather Grab, Claudio Gratton, Lauren Hunt, Ashley E. Larsen, Alejandra Martínez-Salinas, Megan E. O’Rourke, Adrien Rusch, Katja Poveda, Mattias Jonsson, Jay A. Rosenheim, Nancy A. Schellhorn, Teja Tscharntke, Stephen D. Wratten, Wei Zhang, Aaron L. Iverson, Lynn S. Adler, Matthias Albrecht, Audrey Alignier, Gina M. Angelella, Muhammad Zubair Anjum … & Yi Zou
The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are...

Natural Language as a Technological Tool

Simone Aurora
Language is a technological tool, since it is the outcome of a process of exteriorisation of a set of intentional practices. This process of exteriorisation is semiotic in nature. Language as technology and technology as language are thus ways of socialize consciousness. On the basis of some recent results in applied linguistics, the paper suggests that language and technology have to be considered as “functioning” when they enable social relations, by collectivising consciousness and producing...

Selection experiment on guppy ornamental traits

Magdalena Herdegen-Radwan, Silvia Cattelan, Jakub Buda, Jarosław Raubic & Jacek Radwan
Female preferences for male ornamental traits can arise from indirect benefits, such as increased attractiveness or better viability of progeny, but empirical evidence for such benefits is inconsistent. Artificial selection offers a powerful way to investigate indirect effects of male ornaments. Here, we selected for the area of orange spots on male guppies, a trait subject to female preferences in our population, in replicated up- and down-selected lines. We found a significant direct response to...

Data from: Phylogeography and demographic history of two widespread Indo-Pacific mudskippers (Gobiidae: Periophthalmus)

Gianluca Polgar, Lorenzo Zane, Massimiliano Babbucci, Federica Barbisan, Tomaso Patarnello, Lukas Rüber & Chiara Papetti
This study provides a first description of the phylogeographic patterns and evolutionary history of two species of the mudskipper genus Periophthalmus. These amphibious gobies are distributed throughout the whole Indo-Pacific region and Atlantic coast of Africa, in peritidal habitats of soft-bottom coastal ecosystems. Three sequence datasets of two widely distributed species, Periophthalmus argentilineatus and P. kalolo, were obtained by amplifying and sequencing two mtDNA markers (D-loop and 16S rDNA) and the nDNA rag1 region. The...

Along-shelf connectivity and circumpolar gene flow in Antarctic silverfish (Pleuragramma antarctica)

Jilda Alicia Caccavo, Chiara Papetti, , Rainer Knust, Julian R. Ashford & Lorenzo Zane
The Antarctic silverfish (Pleuragramma antarctica) is a critically important forage species with a circumpolar distribution and is unique among other notothenioid species for its wholly pelagic life cycle. Previous studies have provided mixed evidence of population structure over regional and circumpolar scales. The aim of the present study was to test the recent population hypothesis for Antarctic silverfish, which emphasizes the interplay between life history and hydrography in shaping connectivity. A total of 1067 individuals...

Data from: The interplay of landscape composition and configuration: new pathways to manage functional biodiversity and agro-ecosystem services across Europe

Emily A. Martin, Matteo Dainese, Yann Clough, András Báldi, Riccardo Bommarco, Vesna Gagic, Michael Garratt, Andrea Holzschuh, David Kleijn, Anikó Kovács-Hostyánszki, Lorenzo Marini, Simon G. Potts, Henrik G. Smith, Diab Al Hassan, Matthias Albrecht, Georg K. S. Andersson, Josep Asis, Stephanie Aviron, Mario Balzan, Laura Baños-Picón, Ignasi Bartomeus, Peter Batary, Françoise Burel, Berta Caballero-López, Elena D. Concepcion … & Ingolf Steffan-Dewenter
Managing agricultural landscapes to support biodiversity and ecosystem services is a key aim of a sustainable agriculture. However, how the spatial arrangement of crop fields and other habitats in landscapes impacts arthropods and their functions is poorly known. Synthesising data from 49 studies (1515 landscapes) across Europe, we examined effects of landscape composition (% habitats) and configuration (edge density) on arthropods in fields and their margins, pest control, pollination and yields. Configuration effects interacted with...

Data from: Behavioural patterns of vocal greeting production in four primate species

Pawel Fedurek, Christof Neumann, Yaelle Bouquet, Stephanie Mercier, Martina Magris, Fredy Quintero & Klaus Zuberbühler
Social animals have evolved a range of signals to avoid aggressive and facilitate affiliative interactions. Vocal behaviour is especially important in this respect with many species, including various primates, producing acoustically distinct ‘greeting calls’ when two individuals approach each other. While the ultimate function of greeting calls has been explored in several species, little effort has been made to understand the mechanisms of this behaviour across species. The aim of this study was to explore...

Data from: Familiarity mediates equitable social associations in guppies

Silvia Cattelan, Tyrone Lucon-Xiccato, Andrea Pilastro & Matteo Griggio
Several fish species are characterized by social systems in which individuals prefer to interact with specific group mates. However, there is no clear evidence that such associations are equitable, i.e. they are mutual between individuals. We addressed this issue in the guppy (Poecilia reticulata), a species in which social network analyses have evidenced non-random social associations between individuals. We measured the mutual preference in pairs of guppies that previously familiarized in groups of either two...

Data from: Extra food provisioning reduces extra-pair paternity in the lesser kestrel (Falco naumanni)

Alessandra Costanzo, Nicola Tommasi, Andrea Galimberti, Giorgia Scesa, Roberto Ambrosini, Matteo Griggio, Jacopo G. Cecere & Diego Rubolini
Female promiscuity can function to acquire both direct and indirect benefits from their social mate and extra-pair males. In many raptor species, intense mate-feeding significantly contributes to female energy requirements before and during egg laying. Moreover, females may use mate-feeding effort to assess male quality. In this study of the lesser kestrel (Falco naumanni), we aimed at experimentally manipulating the female’s perception of mate quality by providing females with extra food during egg laying, and...

Data from: Quick-change artists: male guppies pay no cost to repeatedly adjust their sexual strategies

Martina Magris, Gianluca Chimetto, Sofia Rizzi & Andrea Pilastro
Sexually selected traits involved in mate acquisition and fertilization success are usually costly and males often plastically adjust their reproductive investment in response to social conditions. Phenotypic plasticity in male sexual traits is generally assumed to be adaptive, yet its costs are rarely investigated. Male guppies (Poecilia reticulata) adjust their ejaculate production and sexual behavior in response to perceived mating opportunities. In natural populations mating opportunities can fluctuate continuously, and the iterated activation of plastic...

Data from: High cover of hedgerows in the landscape supports multiple ecosystem services in Mediterranean cereal fields

Matteo Dainese, Silvia Montecchiari, Tommaso Sitzia, Maurizia Sigura & Lorenzo Marini
Field-margin diversification through conservation and restoration of hedgerows is becoming a prominent intervention for promoting biodiversity and associated ecosystem services in intensive agricultural landscapes. However, how increasing cover of hedgerows in the landscape can affect ecosystem services has rarely been considered. Here, we assessed the effect of increased field-margin complexity at the local scale and increasing cover of hedgerows in the landscape on the provision of pest control, weed control and potential pollination. Locally, three...

Data from: The replication of Frataxin gene is assured by activation of dormant origins in the presence of a GAA-repeat expansion

Martina Stevanoni, Elisa Palumbo & Antonella Russo
It is well known that DNA replication affects the stability of several trinucleotide repeats, but whether replication profiles of human loci carrying an expanded repeat differ from those of normal alleles is poorly understood in the endogenous context. We investigated this issue using cell lines from Friedreich’s ataxia patients, homozygous for a GAA-repeat expansion in intron 1 of the Frataxin gene. By interphase, FISH we found that in comparison to the normal Frataxin sequence the...

From refugia to contact: pine processionary moth hybrid zone in a complex biogeographic setting

Kahraman İpekdal, Christian Burban, Laure Sauné, Andrea Battisti & Carole Kerdelhué
Contact zones occur at the crossroad between specific dispersal routes and are facilitated by biogeographic discontinuities. Here we focused on two Lepidoptera sister species that come in contact near the Turkish Straits System (TSS). We aimed to infer their phylogeographic histories in the Eastern Mediterranean and finely analyse their co-occurrence and hybridisation patterns in this biogeographical context. We used molecular mitochondrial and nuclear markers to study 224 individuals from 42 localities. We used discordances between...
