Data from: Long-term effects of early nutrition and environmental matching on developmental and personality traits in zebra finches

E. Tobias Krause, Oliver Krüger & Holger Schielzeth
Developmental plasticity is a key feature of many organisms and individuals can benefit from early programming to optimize their phenotypes for the expected environmental conditions. However, environmental conditions may sometimes change unexpectedly. Mismatches between early and adult life, for example, can have important repercussions for adult phenotypes, potentially leading to better performance under matched than mismatched conditions as predicted by the predictive adaptive response hypothesis. We conducted a long-term experimental manipulation of dietary conditions in...

Data from: Intracontinental plant invader shows matching genetic and chemical profiles and might benefit from high defence variation within populations

Lisa Johanna Tewes, Florian Michling, Marcus A. Koch & Caroline Müller
1. Whereas many studies have revealed mechanisms driving plant invasions between continents, research on intracontinental range-expanders is scarce. Therefore, we studied genetic, chemical and ecological traits of a range-expanding Brassicaceae, assuming that high genetic diversity should maintain chemical variation, which potentially benefits the invasion success. Moreover, we expected that within-individual defence diversity plays an essential role in biotic interactions. 2. We compared Bunias orientalis plants from 16 populations of native, invasive or exotic non-invasive origin....

Data from: 2b-RAD genotyping for population genomic studies of Chagas disease vectors: Rhodnius ecuadoriensis in Ecuador

Background: Rhodnius ecuadoriensis is the main triatomine vector of Chagas disease, American trypanosomiasis, in Southern Ecuador and Northern Peru. Genomic approaches and next generation sequencing technologies have become powerful tools for investigating population diversity and structure which is a key consideration for vector control. Here we assess the effectiveness of three different 2b restriction site-associated DNA (2b-RAD) genotyping strategies in R. ecuadoriensis to provide sufficient genomic resolution to tease apart microevolutionary processes and undertake some...

Data from: A load-based mechanism for inter-leg coordination in insects

Chris J. Dallmann, Thierry Hoinville, Volker Dürr & Josef Schmitz
Animals rely on an adaptive coordination of legs during walking. However, which specific mechanisms underlie coordination during natural locomotion remains largely unknown. One hypothesis is that legs can be coordinated mechanically based on a transfer of body load from one leg to another. To test this hypothesis, we simultaneously recorded leg kinematics, ground reaction forces and muscle activity in freely walking stick insects (Carausius morosus). Based on torque calculations, we show that load sensors (campaniform...

Data from: Exploring temporal patterning of psychological skills usage during the week leading up to competition: lessons for developing intervention programmes

, Dietmar Pollmann, Thomas Schack & John Elvis Hagan
Background and purpose: Although sport psychology literature focuses on psychological skills use to promote proficiency, it is still puzzling that current research has focused on psychological skills use only during competition. There remains a scarcity of empirical evidence to support the timing, and content of psychological skill application during the time preceding competition. This study examined the extent to which psychological skills usage are dynamic or stable over a 7-day pre-competitive period and whether any...

Data from: Begging blue tit nestlings discriminate between the odour of familiar and unfamiliar conspecifics

Marta Rossi, Reinaldo Marfull, Sarah Golüke, Jan Komdeur, Peter Korsten & Barbara A. Caspers
1. Offspring often solicit, and compete for, limited parental care by elaborate begging behaviour. Kin selection theory predicts that competing offspring should modify the intensity of their begging depending on the degree of relatedness to their nest- or litter mates. 2. Empirical evidence in birds, which are a key model in the study of parent-offspring interactions, indeed indicates that a lower level of relatedness between offspring in the nest correlates with more intense begging (i.e....

Data from: RAD sequencing resolves fine-scale population structure in a benthic invertebrate: implications for understanding phenotypic plasticity

David L.J. Vendrami, Luca Telesca, Hannah Weigand, Martina Weiss, Katie Fawcett, Katrin Lehman, Melody S. Clark, Florian Leese, Carrie McMinn, Heather Moore & Joseph I. Hoffman
The field of molecular ecology is transitioning from the use of small panels of classical genetic markers such as microsatellites to much larger panels of single nucleotide polymorphisms (SNPs) generated by approaches like RAD sequencing. However, few empirical studies have directly compared the ability of these methods to resolve population structure. This could have implications for understanding phenotypic plasticity, as many previous studies of natural populations may have lacked the power to detect genetic differences,...

Data from: High fidelity: extra-pair fertilisations in eight Charadrius plover species are not associated with parental relatedness or social mating system

Kathryn H. Maher, Luke J. Eberhart-Phillips, András Kosztolányi, Natalie Dos Remedios, María Cristina Carmona-Isunza, Medardo Cruz-López, Sama Zefania, James J. H. St Clair, Monif AlRashidi, Michael A. Weston, Martín A. Serrano-Meneses, Oliver Krüger, Joseph I. Hoffmann, Tamás Székely, Terry Burke, Clemens Küpper & Joseph I. Hoffman
Extra-pair paternity is a common reproductive strategy in many bird species. However, it remains unclear why extra-pair paternity occurs and why it varies among species and populations. Plovers (Charadrius spp.) exhibit considerable variation in reproductive behaviour and ecology, making them excellent models to investigate the evolution of social and genetic mating systems. We investigated inter- and intra-specific patterns of extra-pair parentage and evaluated three major hypotheses explaining extra-pair paternity using a comparative approach based on...

Data from: Differentiation of movement behavior in an adaptively diverging salamander population

Ralf Hendrix, Benedikt R. Schmidt, Michael Schaub, E. Tobias Krause & Sebastian Steinfartz
Dispersal is considered to be a species-specific trait, but intraspecific variation can be high. However, when and how this complex trait starts to differentiate during the divergence of species/lineages is unknown. Here, we studied the differentiation of movement behavior in a large salamander (Salamandra salamandra) population, in which individual adaptations to different habitat conditions drive the genetic divergence of this population into two subpopulations. In this system, salamanders have adapted to the deposition and development...
