Data from: Plio-Pleistocene phylogeography of the Southeast Asian Blue Panchax killifish, Aplocheilus panchax

Samantha V. Beck, Gary R. Carvalho, Axel Barlow, Lukas Rüber, Heok Hui Tan, Estu Nugroho, Daisy Wowor, Siti Azizah Mohd Nor, Fabian Herder, Zainal A. Muchlisin & Mark De Bruyn
The complex climatic and geological history of Southeast Asia has shaped this region’s high biodiversity. In particular, sea level fluctuations associated with repeated glacial cycles during the Pleistocene both facilitated, and limited, connectivity between populations. In this study, we used data from two mitochondrial and three anonymous nuclear markers to determine whether a fresh/brackish water killifish, Aplocheilus panchax, Hamilton, 1822, could be used to further understand how climatic oscillations and associated sea level fluctuations have...

Data from: The effect of top-predator presence and phenotype on aquatic microbial communities

Karen E. Sullam, Blake Matthews, Thierry Aebischer, Ole Seehausen & Helmut Bürgmann
The presence of predators can impact a variety of organisms within the ecosystem, including microorganisms. Because the effects of fish predators and their phenotypic differences on microbial communities have not received much attention, we tested how the presence/absence, genotype, and plasticity of the predatory three-spine stickleback (Gasterosteus aculeatus) influence aquatic microbes in outdoor mesocosms. We reared lake and stream stickleback genotypes on contrasting food resources to adulthood, and then added them to aquatic mesocosm ecosystems...

Data from: Task-dependent workload adjustment of female breeders in a cooperatively breeding fish

Hirokazu Tanaka, Joachim G. Frommen, Leif Engqvist & Masanori Kohda
Parental investment affects the future survival and reproductive success of breeders. Therefore, breeders should optimize the amount of care they invest into the current offspring. In cooperative breeding systems, the amount of breeders’ parental care is influenced by the behavior of brood-care helpers. Such workload adjustment is expected to depend on the task that needs to be fulfilled. While investment rules of breeders in respect to single tasks are well investigated in many bird and...

Data from: Effect of the early social environment on behavioural and genomic responses to a social challenge in a cooperatively breeding vertebrate

Cecilia Nyman, Stefan Fischer, Nadia Aubin-Horth & Barbara Taborsky
The early social environment can have substantial, lifelong effects on vertebrate social behaviour, which can be mediated by developmental plasticity of brain gene expression. Early life effects can influence immediate behavioural responses towards later-life social challenges and can activate different gene expression responses. However, while genomic responses to social challenges have been reported frequently, how developmental experience influences the shape of these genomic reaction norms remains largely unexplored. We tested how manipulating the early social...

Data from: Rapid transgenerational effects in Knautia arvensis in response to plant-community diversity

Tanja Rottstock, Volker Kummer, Markus Fischer & Jasmin Joshi
1. Plant-species persistence in natural communities requires coping with biotic and abiotic challenges. These challenges also depend on plant-community composition and diversity. Over time, biodiversity effects have been shown to be strengthened via increasing species complementarity in mixtures. Little is known, however, whether differences in community diversity and composition induce rapid transgenerational phenotypic adaptive differentiation during community assembly. We expect, altered plant-plant and other biotic interactions (mutualists or antagonists) in high vs. low diverse communities...

Data from: Consistent cooperation in a cichlid fish is caused by maternal and developmental effects rather than heritable genetic variation

Claudia Kasper, Mathias Koelliker, Erik Postma & Barbara Taborsky
Studies on the evolution of cooperative behaviour are typically confined to understanding its adaptive value. It is equally essential, however, to understand its potential to evolve, requiring knowledge about the phenotypic consistency and genetic basis of cooperative behaviour. While previous observational studies reported considerably high heritabilities of helping behaviour in cooperatively breeding vertebrates, experimental studies disentangling the relevant genetic and non-genetic components of cooperative behaviour are lacking. In a half-sibling breeding experiment, we investigated the...

Data from: Experience buffers extrinsic mortality in a group-living bird species

Michael Griesser, Emeline Mourocq, Jonathan Barnaby, Katharine Bowegen, Sönke Eggers, Kevin Fletcher, Radoslav Kozma, Franziska Kurz, Anssi Laurila, Magdalena Nystrand, Enrico Sorato, Jan Ekman & Katharine M. Bowgen
Extrinsic mortality has a strong impact on the evolution of life-histories, prey morphology and behavioural adaptations, but for many animals the causes of mortality are poorly understood. Predation is an important driver of extrinsic mortality and mobile animals form groups in response to increased predation risk. Furthermore, in many species juveniles suffer higher mortality than older individuals, which may reflect a lower phenotypic quality, lower competitiveness, or a lack of antipredator or foraging skills. Here...

Data from: Multiple independent colonizations into the Congo Basin during the continental radiation of African Mastacembelus spiny eels

Julia J. Day, Antonie Fages, Katherine J. Brown, Emmanuel J. Vreven, Melanie L. J. Stiassny, Roger Bills, John P. Friel, Lukas Rüber & Antoine Fages
Aim: There has been recent interest in the origin and assembly of continental biotas based on densely sampled species-level clades, however, studies from African freshwaters are few so that the commonality of macroevolutionary patterns and processes among continental clades remain to be tested. Within the Afrotropics, the Congo Basin contains the highest diversity of riverine fishes, yet it is unclear how this fauna was assembled. To address this, and the diversification dynamics of a continental...

Data from: Major histocompatibility complex-linked social signalling affects female fertility

Dominik Burger, Selina Thomas, Helen Aepli, Margaux Dreyer, Guillaume Fabre, Eliane Marti, Harald Sieme, M. R. Robinson & Claus Wedekind
Genes of the major histocompatibility complex (MHC) have been shown to influence social signalling and mate preferences in many species, including humans. First observations suggest that MHC signalling may also affect female fertility. To test this hypothesis, we exposed 191 female horses (Equus caballus) to either a MHC-similar or a MHC-dissimilar stimulus male around the time of ovulation and conception. A within-subject experimental design controlled for non-MHC linked male characteristics, and instrumental insemination with semen...

Juergen Kreyling, Jürgen Dengler, Julia Walter, Nikolay Velev, Emin Ugurlu, Desislava Sopotlieva, Johannes Ransijn, Catherine Picon-Cochard, Ivan Nijs, Pauline Hernandez, Behlül Güler, Philipp Von Gillhaussen, Hans J. De Boeck, Juliette M. G. Bloor, Sigi Berwaers, Carl Beierkuhnlein, Mohammed A. S. Arfin Khan, Iva Apostolova, Yasin Altan, Michaela Zeiter, Camilla Wellstein, Marcelo Sternberg, Andreas Stampfli, Giandiego Campetella, Sándor Bartha … & Juliette M.G. Bloor
Biodiversity can buffer ecosystem functioning against extreme climatic events, but few experiments have explicitly tested this. Here, we present the first multisite biodiversity × drought manipulation experiment to examine drought resistance and recovery at five temperate and Mediterranean grassland sites. Aboveground biomass production declined by 30% due to experimental drought (standardised local extremity by rainfall exclusion for 72–98 consecutive days). Species richness did not affect resistance but promoted recovery. Recovery was only positively affected by...

Data from: Prioritizing sites for ecological restoration based on ecosystem services

Francisco A. Comín, Beatriz Miranda, Ricardo Sorando, María R. Felipe-Lucia, Juan J. Jiménez & Enrique Navarro
1. Restoration ecology is moving towards designing restoration actions to maximize ecosystem services (ES). Such restoration actions require planning at large spatial scales, as these are often more meaningful for ecosystem functioning and ES supply. As economic resources to undertake ecological restoration at large scales are scarce, prioritizing sites to enhance multiple ES supply is critical. 2. Our study presents an index, the Relative Aggregated Value of ES (RAVES), to prioritize sites for ecological restoration...

Data from: Barcoding snakeheads (Teleostei, Channidae) revisited: discovering greater species diversity and resolving perpetuated taxonomic confusions

Cecilia Conte-Grand, Ralf Britz, Neelesh Dahanukar, Rajeev Raghavan, Rohan Pethiyagoda, Hoek Hui Tan, Renny Kurnia Hadiaty, Norsham S. Yaakob, Lukas Rüber & Heok Hui Tan
Snakehead fishes of the family Channidae are predatory freshwater teleosts from Africa and Asia comprising 38 valid species. Snakeheads are important food fishes (aquaculture, live food trade) and have been introduced widely with several species becoming highly invasive. A channid barcode library was recently assembled by Serrao and co-workers to better detect and identify potential and established invasive snakehead species outside their native range. Comparing our own recent phylogenetic results of this taxonomically confusing group...

Data from: Stallion semen quality depends on MHC matching to teaser mare

Elise Jeannerat, Eliane Marti, Catherine Berney, Fredi Janett, Heinrich Bollwein, Harald Sieme, Dominik Burger & Claus Wedekind
The major histocompatibility complex (MHC) has repeatedly been found to influence mate choice of vertebrates, with MHC-dissimilar mates typically being preferred over MHC-similar mates. We used horses (Equus caballus) to test whether MHC matching also affects male investment into ejaculates after short exposure to a female. Semen characteristics varied much among stallions. Controlling for this variance with a full-factorial within-subject experimental design, we found that a short exposure to an MHC-dissimilar mare enhanced male plasma...

Data from: Identifying drivers of breeding success in a long-distance migrant using structural equation modelling

Guillaume Souchay, Rien E. Van Wijk, Michael Schaub & Silke Bauer
In migrant animals, conditions encountered at various times and places throughout their annual cycle may affect breeding success. Yet, most studies so far have only investigated the effect of specific parts of the annual cycle, despite the importance to understand how different stages can interact and how these stages compare to intrinsic quality to properly modulate breeding success. Using a structural equation modelling approach, we investigated drivers of breeding success (migration cycle, individual quality, breeding...

Data from: Wild birds respond to flockmate loss by increasing their social network associations to others

Josh A. Firth, Bernhard Voelkl, Ross A. Crates, Lucy M. Aplin, Dora Biro, Darren P. Croft & Ben C. Sheldon
Understanding the consequences of losing individuals from wild populations is a current and pressing issue, yet how such loss influences the social behaviour of the remaining animals is largely unexplored. Through combining the automated tracking of winter flocks of over 500 wild great tits (Parus major) with removal experiments, we assessed how individuals' social network positions responded to the loss of their social associates. We found that the extent of flockmate loss that individuals experienced...

Data from: Neighborhood effects determine plant-herbivore interactions below ground

Wei Huang, Elias Zwimpfer, Maxime R. Hervé, Zoe Bont & Matthias Erb
1. Plant neighbors can strongly influence the interactions between herbivores and focal plants, for instance by providing food of different quality (consumptive effects) or by changing the behavior and metabolism of the herbivore and the focal plant without being consumed (non-consumptive effects). Determining the species-specific contributions of consumptive and non-consumptive effects is important to understand the ecophysiological mechanisms which underlie neighborhood effects. 2. We quantified the impact of nine different grassland plant species on the...

Data from: Livestock activity increases exotic plant richness, but wildlife increases native richness, with stronger effects under low productivity

David J. Eldridge, Manuel Delgado-Baquerizo, Samantha K. Travers, James Val, Ian Oliver, Josh W. Dorrough & Santiago Soliveres
1.Grazing by domestic livestock is one of the most widespread land uses worldwide, particularly in rangelands, where it co-occurs with grazing by wild herbivores. Grazing effects on plant diversity are likely to depend on intensity of grazing, herbivore type, coevolution with plants and prevailing environmental conditions. 2.We collected data on climate, plant productivity, soil properties, grazing intensity and herbivore type; and measured their effects on plant species richness from 451 sites across 0.4 M km2...

Data from: Many-to-one form-to-function mapping weakens parallel morphological evolution

Cole J. Thompson, Newaz Ahmed, Thor Veen, Catherine Lynn Peichel, Andrew P. Hendry, Daniel I. Bolnick & Yoel E. Stuart
Evolutionary ecologists aim to explain and predict evolutionary change under different selective regimes. Theory suggests that such evolutionary prediction should be more difficult for biomechanical systems in which different trait combinations generate the same functional output: “many-to-one mapping”. Many-to-one mapping of phenotype to function enables multiple morphological solutions to meet the same adaptive challenges. Therefore, many-to-one mapping should undermine parallel morphological evolution, and hence evolutionary predictability, even when selection pressures are shared among populations. Studying...

Data from: A prioritised list of invasive alien species to assist the effective implementation of EU legislation

Carles Carboneras, Piero Genovesi, Montserrat Vila, Tim Blackburn, Martina Carrete, Miguel Clavero, Bram D'hondt, Jorge F. Orueta, Belinda Gallardo, Pedro Geraldes, Pablo González-Moreno, Richard D. Gregory, Wolfgang Nentwig, Jean-Yves Paquet, Petr Pysek, Wolfgang Rabitsch, Iván Ramírez, Riccardo Scalera, Jose Tella, Paul Walton, Robin Wynde & Tim M. Blackburn
1. Effective prevention and control of invasive species generally relies on a comprehensive, coherent and representative list of species that enables resources to be used optimally. European Union (EU) Regulation 1143/2014 on invasive alien species (IAS) aims to control or eradicate priority species, and to manage pathways to prevent the introduction and establishment of new IAS; it applies to species considered of Union concern and subject to formal risk assessment. So far, 49 species have...

Data from: Environmental variation is a major predictor of global trait turnover in mammals

Ben G. Holt, Gabriel C. Costa, Caterina Penone, Jean-Philippe Lessard, Thomas M. Brooks, Ana D. Davidson, S. Blair Hedges, Volker C. Radeloff, Carsten Rahbek, Carlo Rondinini & Catherine H. Graham
Aim: To evaluate how environment and evolutionary history interact to influence global patterns of mammal trait diversity (a combination of 14 morphological and life-history traits). Location: The global terrestrial environment. Taxon: Terrestrial mammals. Methods: We calculated patterns of spatial turnover for mammalian traits and phylogenetic lineages using the mean nearest taxon distance. We then used a variance partitioning approach to establish the relative contribution of trait conservatism, ecological adaptation and clade specific ecological preferences on...

Data from: Genetic coupling of female mate choice with polygenic ecological divergence facilitates stickleback speciation

Rachael A. Bay, Matthew E. Arnegard, Gina L. Conte, Jacob Best, Nicole L. Bedford, Shaugnessy R. McCann, Matthew E. Dubin, Yingguang Frank Chan, Felicity C. Jones, David M. Kingsley, Dolph Schluter & Catherine L. Peichel
Ecological speciation with gene flow is widespread in nature, but it presents a conundrum: how are associations between traits under divergent natural selection and traits that contribute to assortative mating maintained? Theoretical models suggest that genetic mechanisms inhibiting free recombination between loci underlying these two types of traits (hereafter, “genetic coupling”) can facilitate speciation. Here, we perform a direct test for genetic coupling by mapping both divergent traits and female mate choice in a classic...

Data from: Revised time scales of RNA virus evolution based on spatial information

Moritz Saxenhofer, Vanessa Weber De Melo, Rainer G. Ulrich & Gerald Heckel
The time scales of pathogen evolution are of major concern in the context of public and veterinary health, epidemiology and evolutionary biology. Dating the emergence of a pathogen often relies on estimates of evolutionary rates derived from nucleotide sequence data. For many viruses, this has yielded estimates of evolutionary origins only a few hundred years in the past. Here we demonstrate through the incorporation of geographic information from virus sampling that evolutionary age estimates of...

Data from: Canine brachycephaly is associated with a retrotransposon-mediated missplicing of SMOC2

Thomas W. Marchant, Edward J. Johnson, Lynn McTeir, Craig I. Johnson, Adam Gow, Tiziana Liuti, Dana Kuehn, Karen Svenson, Mairead L. Bermingham, Michaela Drögemüller, Marc Nussbaumer, Megan G. Davey, David J. Argyle, Roger M. Powell, Sérgio Guilherme, Johann Lang, Gert Ter Haar, Tosso Leeb, Tobias Schwarz, Richard J. Mellanby, Dylan N. Clements & Jeffrey J. Schoenebeck
In morphological terms, “form” is used to describe an object’s shape and size. In dogs, facial form is stunningly diverse. Facial retrusion, the proximodistal shortening of the snout and widening of the hard palate is common to brachycephalic dogs and is a welfare concern, as the incidence of respiratory distress and ocular trauma observed in this class of dogs is highly correlated with their skull form. Progress to identify the molecular underpinnings of facial retrusion...

Data from: A web platform for landuse, climate, demography, hydrology and beach erosion in the Black Sea catchment

Anthony Lehmann, Yaniss Guigoz, Nicolas Ray, Emanuele Mancuso, Karim C. Abbaspour, Elham Rouholahnejad Freund, Karin Allenbach, Andrea De Bono, Marc Fasel, Ana Gago-Silva, Roger Bär, Pierre Lacroix & Grégory Giuliani
The Black Sea catchment (BSC) is facing important demographic, climatic and landuse changes that may increase pollution, vulnerability and scarcity of water resources, as well as beach erosion through sea level rise. Limited access to reliable time-series monitoring data from environmental, statistical, and socio-economical sources is a major barrier to policy development and decision-making. To address these issues, a web-based platform was developed to enable discovery and access to key environmental information for the region....

Data from: Riders in the sky (islands): using a mega-phylogenetic approach to understand plant species distribution and coexistence at the altitudinal limits of angiosperm plant life

Hannah E. Marx, Cédric Dentant, Julien Renaud, Romain Delunel, David C. Tank & Sébastien Lavergne
Aim: Plants occurring on high-alpine summits are generally expected to persist due to adaptations to extreme selective forces caused by the harshest climates where angiosperm life is known to thrive. We assessed the relative effects of this strong environmental filter and of other historical and stochastic factors driving plant community structure in very high-alpine conditions. Location: European Alps, Écrins National Park, France. Methods: Using species occurrence data collected from floristic surveys on 15 summits (2,791–4,102...
