Data from: Global patterns in threats to vertebrates by biological invasions

Celine Bellard, Piero Genovesi & Jonathan M. Jeschke
Biological invasions as drivers of biodiversity loss have recently been challenged. Fundamentally, we must know where species that are threatened by invasive alien species (IAS) live, and the degree to which they are threatened. We report the first study linking 1,372 vertebrates threatened by more than 200 IAS from the completely revised Global Invasive Species Database. New maps of the vulnerability of threatened vertebrates to IAS permit assessments of whether IAS have a major influence...

Data from: Repeatability, heritability, and age-dependence in the aggressiveness reaction norms of a wild passerine bird

Yimen Gerardo Araya Ajoy, Niels J. Dingemanse & Yimen G. Araya-Ajoy
Labile characters allow individuals to flexibly adjust their phenotype to changes in environmental conditions. There is growing evidence that individuals can differ both in average expression and level of plasticity in this type of character. Both of these aspects are studied in conjunction within a reaction norm framework. Theoreticians have investigated the factors promoting variation in reaction norm intercepts (average phenotype) and slopes (level of plasticity) of a key labile character: behaviour. A general prediction...

Data from: Manipulating virulence factor availability can have complex consequences for infections

Michael Weigert, Adin Ross-Gillespie, Anne Leinweber, Gabriella Pessi, Sam P. Brown & Rolf Kuemmerli
Given the rise of bacterial resistance against antibiotics, we urgently need alternative strategies to fight infections. Some propose we should disarm rather than kill bacteria, through targeted disruption of their virulence factors. It is assumed that this approach (i) induces weak selection for resistance because it should only minimally impact bacterial fitness, and (ii) is specific, only interfering with the virulence factor in question. Given that pathogenicity emerges from complex interactions between pathogens, hosts, and...

Data from: Sources of (co)variation in alternative siring routes available to male great tits (Parus major)

Yimen G. Araya-Ajoy, Sylvia Kuhn, Kimberley J. Mathot, Alexia Mouchet, Ariane Mutzel, Marion Nicolaus, Jan J. Wijmenga, Bart Kempenaers & Niels J. Dingemanse
Males of socially monogamous species can increase their siring success via within-pair and extra-pair fertilizations. In this study, we focused on the different sources of (co)variation between these siring routes, and asked how each contributes to total siring success. We quantified the fertilization routes to siring success, as well as behaviors that have been hypothesized to affect siring success, over a five-year period for a wild population of great tits Parus major. We considered siring...

Data from: Multidimensional environmental predictors of variation in avian forest and city life histories

Philipp Sprau, Alexia Mouchet & Niels J. Dingemanse
Optimal life-history decisions are shaped by prevailing environmental conditions. In the context of urbanization, environmental differences between urban and rural areas are known to vary across a multitude of axes. The relative roles of specific axes and whether they explain variation in avian life histories between forest and city populations have not often been studied empirically. This study comprehensively views urbanization from a multidimensional environmental perspective. For each of 13 nest box plots of a...

Data from: Phylogenomic analysis supports the ancestral presence of LPS-outer membranes in the Firmicutes

Luisa C. S. Antunes, Daniel Poppleton, Andreas Klingl, Alexis Criscuolo, Bruno Dupuy, Céline Brochier-Armanet, Christophe Beloin, Simonetta Gribaldo & Luisa CS Antunes
One of the major unanswered questions in evolutionary biology is when and how the transition between diderm (two membranes) and monoderm (one membrane) cell envelopes occurred in Bacteria. The Negativicutes and the Halanaerobiales belong to the classically monoderm Firmicutes, but possess outer membranes with lipopolysaccharide (LPS-OM). Here, we show that they form two phylogenetically distinct lineages, each close to different monoderm relatives. In contrast, their core LPS biosynthesis enzymes were inherited vertically, as in the...

Data from: Genetic Allee effects and their interaction with ecological Allee effects

Meike J. Wittmann, Hanna Stuis & Dirk Metzler
1. It is now widely accepted that genetic processes such as inbreeding depression and loss of genetic variation can increase the extinction risk of small populations. However, it is generally unclear whether extinction risk from genetic causes gradually increases with decreasing population size or whether there is a sharp transition around a specific threshold population size. In the ecological literature, such threshold phenomena are called “strong Allee effects” and they can arise for example from...

Data from: Epithelial magnesium transport by TRPM6 is essential for prenatal development and adult survival

Vladimir Chubanov, Thomas Gudermann, Wenke Jonas, Annette Schürmann, Önder A Yildirim, Yuriy Shymkiv, Alexey G Ryazanov, Christian Weber, Emiel PC Van Der Vorst, Harald Bartsch, Karl Sotlar, Attila Braun, David G Simmons, Silvia Ferioli, Annika Wisnowsky, Banu Akdogan, Lorenz Mittermeier, Ludmila Sytik, Susanna Zierler & Vindi Jurinovic
Mg2+ regulates many physiological processes and signalling pathways. However, little is known about the mechanisms underlying the organismal balance of Mg2+. Capitalizing on a set of newly generated mouse models, we provide an integrated mechanistic model of the regulation of organismal Mg2+ balance during prenatal development and in adult mice by the ion channel TRPM6. We show that TRPM6 activity in the placenta and yolk sac is essential for embryonic development. In adult mice, TRPM6...

Data from: Assessing patterns in introduction pathways of alien species by linking major invasion databases

Wolf-Christian Saul, Helen E. Roy, Olaf Booy, Lucilla Carnevali, Hsuan-Ju Chen, Piero Genovesi, Colin A. Harrower, Philip E. Hulme, Shyama Pagad, Jan Pergl & Jonathan M. Jeschke
1. Preventing the arrival of invasive alien species (IAS) is a major priority in managing biological invasions. However, information on introduction pathways is currently scattered across many databases that often use different categorisations to describe similar pathways. This hampers the identification and prioritisation of pathways in order to meet the main targets of recent environmental policies. 2. Therefore, we integrate pathway information from two major IAS databases, IUCN's Global Invasive Species Database (GISD) and the...

Data from: Good reasons to leave home: proximate dispersal cues in a social spider

Reut Berger-Tal, Na'ama Berner Aharon, Shlomi Aharon, Cristina Tuni & Yael Lubin
Natal dispersal is a successful tactic under a range of conditions in spite of significant costs. Habitat quality is a frequent proximate cause of dispersal, and studies have shown that dispersal increases both when natal habitat quality is good or poor. In social species kin competition, favoring dispersal, may be balanced by the benefits of group living, favoring philopatry. We investigated the effect of changes in the local environment on natal dispersal of adult females...

Data from: Estimation of self-motion duration and distance in rodents

Magdalena Kautzky & Kay Thurley
Spatial orientation and navigation rely on information about landmarks and self-motion cues gained from multi-sensory sources. In this study, we focused on self-motion and examined the capability of rodents to extract and make use of information about own movement, i.e. path integration. Path integration has been investigated in depth in insects and humans. Demonstrations in rodents, however, mostly stem from experiments on heading direction; less is known about distance estimation. We introduce a novel behavioural...

Data from: Parental and hybrid Daphnia from the D. longispina complex: long-term dynamics in genetic structure and significance of overwintering modes

Johanna Griebel, Sabine Gießler, Mingbo Yin & Justyna Wolinska
In recent decades, hybridization has become a focus of attention because of its role in evolutionary processes. However, little is known about changes in genetic structure within and between parental species and hybrids over time. Here, we studied processes of genetic change in parental species and hybrids from the Daphnia longispina complex (Crustacea, Cladocera) over a period of six years across ten habitats. These cyclical parthenogens respond to fluctuating environments by switching from asexual to...

Data from: The assembly of ant-farmed gardens: mutualism specialization following host broadening

Guillaume Chomicki, Milan Janda & Susanne S. Renner
Ant-gardens (AGs) are ant/plant mutualisms in which ants farm epiphytes in return for nest space and food rewards. They occur in the Neotropics and Australasia, but not in Africa, and their evolutionary assembly remains unclear. We here use phylogenetic frameworks for important AG lineages in Australasia, namely the ant genus Philidris and domatium-bearing ferns (Lecanopteris) and flowering plants in the Apocynaceae (Hoya and Dischidia) and Rubiaceae (Myrmecodia, Hydnophytum, Anthorrhiza, Myrmephytum and Squamellaria). Our analyses revealed...

Data from: Bioinformatic processing of RAD-seq data dramatically impacts downstream population genetic inference

Aaron B. A. Shafer, Claire R. Peart, Sergio Tusso, Inbar Maayan, Alan Brelsford, Christopher W. Wheat & Jochen B. W. Wolf
Restriction site-associated DNA sequencing (RAD-seq) provides high-resolution population genomic data at low cost, and has become an important component in ecological and evolutionary studies. As with all high-throughput technologies, analytic strategies require critical validation to ensure accurate and unbiased interpretation. To test for the impact of bioinformatic data processing on downstream population genetic inferences, we analysed mammalian RAD-seq data (>100 individuals) with 312 combinations of methodology (de novo vs. mapping to references of increasing divergence)...

Data from: Synergistic impacts by an invasive amphipod and an invasive fish explain native gammarid extinction

Sebastian Beggel, Joerg Brandner, Alexander F. Cerwenka & Juergen Geist
Background: Worldwide freshwater ecosystems are increasingly affected by invasive alien species. In particular, Ponto-Caspian gobiid fishes and amphipods are suspected to have pronounced effects on aquatic food webs. However, there is a lack of systematic studies mechanistically testing the potential synergistic effects of invasive species on native fauna. In this study we investigated the interrelations between the invasive amphipod Dikerogammarus villosus and the invasive fish species Neogobius melanostomus in their effects on the native amphipod...

Data from: The correlation between colouration and exploration behaviour varies across hierarchical levels in a wild passerine bird

Marion Nicolaus, Romain Piault, Richard Ubels, Joost M. Tinbergen & Niels J. Dingemanse
IIn vertebrates, darker individuals are often found to be more active and willing to take risks (representing characteristics of a ‘proactive’ coping style), whereas lighter individuals are instead more cautious and less active (representing characteristics of a ‘reactive’ coping style). It is thus generally expected that melanin-based colouration and proactivity form a suite of positively integrated traits at the among-individual level. Here we use a multi-generational pedigree of free-living great tits (Parus major) to partition...
