Data from: Isolation by distance, resistance and/or clusters? Lessons learned from a forest-dwelling carnivore inhabiting a heterogeneous landscape

Aritz Ruiz-González, Samuel A. Cushman, María José Madeira, Benjamín J. Gómez-Moliner & Ettore Randi
Landscape genetics provides a valuable framework to understand how landscape features influence gene flow and to disentangle the factors that lead to discrete and/or clinal population structure. Here, we attempt to differentiate between these processes in a forest-dwelling small carnivore [European pine marten (Martes martes)]. Specifically, we used complementary analytical approaches to quantify the spatially explicit genetic structure and diversity and analyse patterns of gene flow for 140 individuals genotyped at 15 microsatellite loci. We...

Data from: A hypervariable mitochondrial protein coding sequence associated with geographical origin in a cosmopolitan bloom-forming alga, Heterosigma akashiwo

Aiko Higashi, Satoshi Nagai, Sergio Seone & Shoko Ueki
Geographic distributions of phytoplankton species can be defined by events on both evolutionary time and shorter scales, e.g., recent climate changes. Additionally, modern industrial activity, including the transport of live fish and spat for aquaculture and aquatic microorganisms in ship ballast water, may aid the spread of phytoplankton. Obtaining a reliable marker is key to gaining insight into the phylogeographic history of a species. Here, we report a hypervariable mitochondrial gene in the cosmopolitan bloom-forming...

Variability In The Accuracy Of Self-Assessments Among Low, Moderate, And High Performing Students in University Education

Samuel Parra León, Antonio Pantoja Vallejo & James Byron Nelson
The present work empirically examines the validity of Student Self-Assessment (SSA) as an educational assessment in higher education. We briefly review the principle methodological factors that could affect SSA validity, as well as the main findings identified in the literature. One empirical study is presented that compares student-self evaluations on a test with the evaluation made by the course instructor while controlling for students' experience with SSA, criteria, rubric, and scales used by the student...

Data from: The foraging ecology of the Mountain long-eared bat Plecotus macrobullaris revealed with DNA mini-barcodes

Antton Alberdi, Inazio Garin, Ostaizka Aizpurua & Joxerra Aihartza
Molecular analysis of diet overcomes the considerable limitations of traditional techniques for identifying prey remains in bat faeces. We collected faeces from individual Mountain long-eared bats Plecotus macrobullaris trapped using mist nets during the summers of 2009 and 2010 in the Pyrenees. We analysed their diet using DNA mini-barcodes to identify prey species. In addition, we inferred some basic features of the bat’s foraging ecology that had not yet been addressed. P. macrobullaris fed almost...

Data from: Dissecting the hydrological niche: soil moisture, space and lifespan

Gonzalo García-Baquero, Jonathan Silvertown, David J. Gowing & Cipriano J. Valle
Questions: Are communities structured on a hydrological (soil moisture) gradient? Is there spatial segregation into hydrological niches? What is the shape of the hydrological niches of individual species? Controlling for spatial autocorrelation, how much of the spatial structure in the community is due to variation in hydrology? Do annuals and perennials behave alike with respect to the above questions? Locations: La Mina in Moscosa Farm, Salamanca, western Spain (dehesa community) and Laguna Larga in the...

Data from: Bayesian analysis of hybridization and introgression between the endangered european mink (Mustela lutreola) and the polecat (Mustela putorius)

Maria Teresa Cabria, Johan R Michaux, Benjamín J Gómez-Moliner, Dimitry Skumatov, Tiit Maran, Pascal Fournier, Javier López De Luzuriaga & Rafael Zardoya
Human-mediated global change will probably increase the rates of natural hybridization and genetic introgression between closely related species, and this will have major implications for conservation of the taxa involved. In this study, we analyse both mitochondrial and nuclear data to characterize ongoing hybridization and genetic introgression between two sympatric sister species of mustelids, the endangered European mink (Mustela lutreola) and the more abundant polecat (M. putorius). A total of 317 European mink, 114 polecats...

Data from: Patterns of species relatedness created by competitive exclusion depend on species niche differences: evidence from Iberian Atlantic grasslands

Iñaki Odriozola, Gonzalo Garcia-Baquero, Ana Etxeberria & Arantza Aldezabal
It is commonly assumed that closely related species share more similar niches than do distantly related species, thus limiting their ability to coexist and leading to patterns of phylogenetic over-dispersion. On the contrary, recent theoretical developments argue that competitive exclusion may lead to patterns of either over-dispersion, clustering or randomness, depending on the relative importance of niche differences and interspecific competitive ability differences. In this study, we utilized semi-natural grassland communities to test the hypothesis...

Data from: \"You are not what you eat: massive parallel sequencing reveals that gut microbiome is not diet-related in larval Dilophus febrilis (Diptera: Bibionidae)\" in Genomic Resources Notes Accepted 1 June 2015 to 31 July 2015

Alexander Rief, Wolfgang Arthofer, Birgit C. Schlick-Steiner, Florian M. Steiner & Julia Seeber
This article documents the public availability of metagenome sequence data from 454 amplicon sequencing of larval dipteran gut (Dilophus febrilis) and their potential food sources dwarf shrub litter (Vaccinium gaultheroides), grass litter (Dactylis glomerata), and cow dung (Bos primigenius taurus).

Data from: Development, characterization and comparisons of targeted and non-targeted metabolomics methods

Anton Ribbenstedt, Haizea Ziarrusta & Jonathan P. Benskin
The potential of a metabolomics method to detect statistically significant perturbations in the metabolome of an organism is enhanced by excellent analytical precision, unequivocal identification, and broad metabolomic coverage. While the former two metrics are usually associated with targeted metabolomics and the latter with non-targeted metabolomics, a systematic comparison of the performance of both approaches has not yet been carried out. The present work reports on the development and performance evaluation of separate targeted and...

Global maps of current (1979-2013) and future (2061-2080) habitat suitability probability for 1,485 European endemic plant species

Robin Pouteau, Idoia Biurrun, Caroline Brunel, Milan Chytrý, Wayne Dawson, Franz Essl, Trevor Fristoe, Rense Haveman, Carsten Hobohm, Florian Jansen, Holger Kreft, Jonathan Lenoir, Bernd Lenzner, Carsten Meyer, Jesper Erenskjold Moeslund, Jan Pergl, Petr Pyšek, Jens-Christian Svenning, Wilfried Thuiller, Patrick Weigelt, Thomas Wohlgemuth, Qiang Yang & Mark Van Kleunen
Aims: The rapid increase in the number of species that have naturalized beyond their native range is among the most apparent features of the Anthropocene. How alien species will respond to other processes of future global changes is an emerging concern and remains largely misunderstood. We therefore ask whether naturalized species will respond to climate and land-use change differently than those species not yet naturalized anywhere in the world. Location: Global Methods: We investigated future...

Data from: Integrating population genetics to define conservation units from the core to the edge of Rhinolophus ferrumequinum western range

Orianne Tournayre, Jean-Baptiste Pons, Maxime Leuchtmann, Raphael Leblois, Sylvain Piry, Anne Loiseau, Ondine Filippi-Codaccioni, Jeanne Duhayer, Inazio Garin, Fiona Mathews, Sébastien Puechmaille, Nathalie Charbonnel & Dominique Pontier
The greater horseshoe bat (Rhinolophus ferrumequinum) is among the most widespread bat species in Europe but it has experienced severe declines, especially in Northern Europe. This species is listed Near Threatened in the European IUCN Red List of Threatened Animals and it is considered to be highly sensitive to human activities and particularly to habitat fragmentation. Therefore, understanding the population boundaries and demographic history of populations of this species is of primary importance to assess...

Stefano Mammola, Pedro Cardoso, Dorottya Angyal, Gergely Balázs, Theo Blick, Hervé Brustel, Julian Carter, Srećko Ćurčić, Samuel Danflous, László Dányi, Sylvain Déjean, Christo Deltshev, Mert Elverici, Jon Fernandez Perez, Fulvio Gasparo, Marjan Komnenov, Christian Komposch, Ľubomír Kováč, Kadir Kuntz, Andrej Mock, Oana Moldovan, Maria Naumova, Martina Pavlek, Carlos Prieto, Carles Ribera … & Marco Isaia
Macroecologists seek to identify drivers of community turnover (β-diversity) through broad spatial scales. Yet, the influence of local habitat features in driving broad-scale β-diversity patterns remains largely untested, due to the objective challenges of associating local-scale variables to continental-framed datasets. We examined the relative contribution of local- versus broad-scale drivers of continental β-diversity patterns, using a uniquely suited dataset of cave-dwelling spider communities across Europe (35–70° latitude). Generalized dissimilarity modeling showed that geographical distance, mean...

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

Jenni Harmoinen, Alina Von Thaden, Jouni Aspi, Laura Kvist, Berardino Cocchiararo, Anne Jarausch, Andrea Gazzola, Teodora Sin, Hannes Lohi, Marjo Hytönen, Ilpo Kojola, Astrid Vik Stronen, Romolo Caniglia, Federica Mattucci, Marco Galaverni, Raquel Godinho, Aritz Ruiz-González, Ettore Randi, Violeta Muñoz-Fuentes & Carsten Nowak
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...

Calcicolous rock-outcrop lime forests in the Cantabrian Mountains and the Western Pyrenees

Dominik Zukal & Idoia Biurrun
We present the first study of the forest vegetation dominated by Tilia platyphyllos growing on cal- careous rock outcrops in the northern part of the Iberian Peninsula. This vegetation is confined to steep rocky slopes of mainly northern aspect in limestone areas. Based on a dataset of 53 relevés recorded during the summer of 2019 and compared with so far described associations of the order Aceretalia pseudoplatani (118 relevés), we describe the new association Helictotricho...

Data from: Dietary overlap and seasonality in three species of mormoopid bats from a tropical dry forest

Valeria B. Salinas-Ramos, Luis Gerardo Herrera Montalvo, Virginia León-Regagnon, Aitor Arrizabalaga-Escudero & Elizabeth L. Clare
Competing hypotheses explaining species’ use of resources have been advanced. Resource limitations in habitat and/or food are factors that affect assemblages of species. These limitations could drive the evolution of morphological and/or behavioural specialization, permitting the coexistence of closely related species through resource partitioning and niche differentiation. Alternatively, when resources are unlimited, fluctuations in resources availability will cause concomitant shifts in resource use regardless of species identity. Here, we used next-generation sequencing to test these...

Data from: Biotic and abiotic variables influencing plant litter breakdown in streams: a global study

Luz Boyero, Richard Pearson, Cang Hui, Mark Gessner, Javier Perez, Markos Alexandrou, Manuel Graça, Bradley Cardinale, Ricardo Albariño, M. Arunachalam, Leon Barmuta, Andrew Boulton, Andreas Bruder, Marcos Callisto, Eric Chauvet, Russell Death, David Dudgeon, Andrea Encalada, Veronica Ferreira, Ricardo Figueroa, Alex Flecker, , Julie Helson, Tomoya Iwata, Tajang Jinggut … & Catherine Yule
Plant litter breakdown is a key ecological process in terrestrial and freshwater ecosystems. Streams and rivers, in particular, have high rates of carbon dioxide evasion and they contribute substantially to global carbon fluxes. However, there is little information available on the relative roles of different drivers of plant litter breakdown in fresh waters, particularly at large scales. We present a global-scale study of litter breakdown in streams to compare the roles of biotic, climatic and...

Data from: Resprouter fraction in Cape Restionaceae assemblages varies with climate and soil type

Rafael O. Wüest, Glenn Litsios, Félix Forest, Christian Lexer, H. Peter Linder, Nicolas Salamin, Niklaus E. Zimmermann & Peter B. Pearman
While fire-induced changes in biodiversity are well documented, less is known about how fire impacts life-history variation and diversity of functional traits that represent distinct strategies for persistence in fire-driven ecosystems. One example is the dichotomy in which ‘resprouter’ species usually survive fires to produce new growth, while ‘reseeder’ species perish and re-establish from seed. Variable relative numbers of reseeder and resprouter species in local assemblages of Restionaceae (Poales) of the Cape Floristic Region (CFR),...

Data from: The context dependence of assortative mating: a demonstration with conspecific salmonid populations

Zoé Gauthey, Andrew P. Hendry, Arturo Elosegi, Cédric Tentelier & Jacques Labonne
Assortative mating is thought to play a key role in reproductive isolation. However, most experimental studies of assortative mating do not take place in multiple natural environments and, hence, they ignore its potential context dependence. We implemented an experiment in which two populations of brown trout (Salmo trutta) with different natural flow regimes were placed into semi-natural stream channels under two different artificial flow regimes. Natural reproduction was allowed and reproductive isolation was measured by...

Data from: Decoding and encoding models reveal the role of mental simulation in the brain representation of meaning

David Soto, Usman Ayub Sheikh, Ning Mei & Roberto Santana
How the brain representation of conceptual knowledge vary as a function of processing goals, strategies and task-factors remains a key unresolved question in cognitive neuroscience. Here we asked how the brain representation of semantic categories is shaped by the depth of processing during mental simulation. Participants were presented with visual words during functional magnetic resonance imaging (fMRI). During shallow processing, participants had to read the items. During deep processing, they had to mentally simulate the...

Data from: 18S rRNA V9 metabarcoding for diet characterization: a critical evaluation with two sympatric zooplanktivorous fish species

Aitor Albaina, Mikel Aguirre, David Abad, María Santos & Andone Estonba
The potential of the 18S rRNA V9 metabarcoding approach for diet assessment was explored using MiSeq paired-end (PE; 2 × 150 bp) technology. To critically evaluate the method′s performance with degraded/digested DNA, the diets of two zooplanktivorous fish species from the Bay of Biscay, European sardine (Sardina pilchardus) and European sprat (Sprattus sprattus), were analysed. The taxonomic resolution and quantitative potential of the 18S V9 metabarcoding was first assessed both in silico and with mock...

Data from: Ecological and historical determinants of population genetic structure and diversity in the Mediterranean shrub Rosmarinus officinalis (Lamiaceae)

José Gabriel Segarra-Moragues, Yolanda Carrión Marco, María Clara Castellanos, María José Molina & Patricio García-Fayos
Population genetic studies of widespread Mediterranean shrubs are scarce compared with those of trees and narrow endemics or studies from phylogeographical perspectives, despite the key role these species may play in Mediterranean ecosystems. Knowledge on the effect of ecological factors in shaping their genetic patterns is also limited. In this study we investigate genetic diversity and population structure across 18 populations of Rosmarinus officinalis, a Mediterranean shrubland plant. Populations were sampled along two elevational gradients,...

Data from: Radar wind profilers and avian migration - a qualitative and quantitative assessment verified by thermal imaging and moon watching

Nadja Weisshaupt, Volker Lehmann, Juan Arizaga & Mercedes Maruri
1. Radars of various types have been used in ornithological research for about 70 years. However, the potential of radar wind profiler (RWP) as a tool for biological purposes remains poorly understood. The aim of this study is to assess the suitability of RWP for ornithological research questions. 2. A 1290 MHz RWP at the southeastern coast of the Bay of Biscay has been known to exhibit seasonally occurring nocturnal signals attributed to migrating birds....

Data from: Genetic structure and post-glacial expansion of Cornus florida L. (Cornaceae): integrative evidence from phylogeography, population demographic history, and species distribution modeling

Ashley Call, Yan-Xia Sun, Yan Yu, Peter B. Pearman, David T. Thomas, Robert Trigiano, Ignazio Carbone, Qiu-Yun Xiang, Robert N. Trigiano, Yan-Xia Sun & Qiu-Yun Jenny Xiang
Repeated global climatic cooling and warming cycles during the Pleistocene played a major role in the distribution and evolution of the Earth biota. Here, we integrate phylogeography, coalescent-based Bayesian estimation of demographic history, and species distribution modeling (SDM) to understand the genetic patterns and biogeography of the flowering dogwood, Cornus florida subsp. florida L., since the Last Glacial Maximum (LGM). Natural populations of the species are severely threatened by dogwood anthracnose. We genotyped 306 plants...

Data from: Stream nitrogen concentration, but not plant N-fixing capacity, modulates litter diversity effects on decomposition

Alan M. Tonin, Luz Boyero, Silvia Monroy, Ana Basaguren, Javier Perez, Richard G. Pearson, Bradley J. Cardinale, & Jesus Pozo
1. We are facing major biodiversity loss and there is evidence that such loss can alter ecosystem functioning. However, the effects of plant diversity on decomposition – a key component of the global carbon cycle – are still unclear. A recent study suggested that a plant trait – their nitrogen (N)-fixing capacity – could mediate effects of litter diversity on decomposition by means of a microbial transfer of N from N-fixers to non-fixers. 2. We...

Data from: Re-visiting the phylogeography and demography of European badgers (Meles meles) based on broad sampling, multiple markers and simulations

Alain C. Frantz, Allan D. McDevitt, Lisa C. Pope, Joanna Kochan, John Davison, Chris F. Clements, Morten Elmeros, Guillem Molina-Vacas, Aritz Ruiz-Gonzalez, Alessandro Balestrieri, Koen Van Den Berge, Peter Breyne, Emmanuel Do Linh San, Erik O. Ågren, Franz Suchentrunk, Laurent Schley, Rafał Kowalczyk, Berit I. Kostka, Dusko Ćirović, Nikica Šprem, Marc Colyn, Marco Ghirardi, Venislava Racheva, Christophe Braun, Rita Oliveira … & Terry Burke
Although the phylogeography of European mammals has been extensively investigated since the 1990s, many studies were limited in terms of sampling distribution, the number of molecular markers used and the analytical techniques employed, frequently leading to incomplete postglacial recolonisation scenarios. The broad-scale genetic structure of the European badger (Meles meles) is of interest as it may result from historic restriction to glacial refugia and/or recent anthropogenic impact. However, previous studies were based mostly on samples...
