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...

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: 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: 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: 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: Species richness effects on grassland recovery from drought depend on community productivity in a multisite experiment

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: The genetics of mate preferences in hybrids between two young and sympatric Lake Victoria cichlid species

Ola Svensson, Katie Woodhouse, Cock Van Oosterhout, Alan Smith, George F. Turner & Ole Seehausen
The genetic architecture of mate preferences is likely to affect significant evolutionary processes, including speciation and hybridization. Here, we investigate laboratory hybrids between a pair of sympatric Lake Victoria cichlid fish species that appear to have recently evolved from a hybrid population between similar predecessor species. The species demonstrate strong assortative mating in the laboratory, associated with divergent male breeding coloration (red dorsum versus blue). We show in a common garden experiment, using DNA-based paternity...

Data from: Plasticity contributes to a fine-scale depth gradient in sticklebacks’ visual system

Thor Veen, Chad Brock, Diana Rennison & Daniel Bolnick
The light environment influences an animal’s ability to forage, evade predators, and find mates, and consequently is known to drive local adaptation of visual systems. However, the light environment may also vary over fine spatial scales at which genetic adaptation is difficult. For instance, in aquatic systems the available wavelengths of light change over a few meters depth. Do animals plastically adjust their visual system to such small-scale environmental light variation? Here, we show that...

Data from: Introgressive replacement of natives by invading Arion pest slugs

Miriam Andela Zemanova, Eva Knop & Gerald Heckel
Hybridization with invasive species is one of the major threats to the phenotypic and genetic persistence of native organisms worldwide. Arion vulgaris (syn. lusitanicus) is a major agricultural pest slug that successfully invaded many European countries in recent decades, but its impact on closely related native species remains unclear. Here, we hypothesized that the regional decline of native A. rufus is connected with the spread of invasive A. vulgaris, and tested whether this can be...

Data from: Evolutionary divergence in life history traits among populations of the Lake Malawi cichlid fish Astatotilapia calliptera

Paul J. Parsons, Jon R. Bridle, Lukas Rüber & Martin J. Genner
During the early stages of adaptive radiation, populations diverge in life history traits such as egg size and growth rates, in addition to eco-morphological and behavioral characteristics. However, there are few studies of life history divergence within ongoing adaptive radiations. Here, we studied Astatotilapia calliptera, a maternal mouthbrooding cichlid fish within the Lake Malawi haplochromine radiation. This species occupies a rich diversity of habitats, including the main body of Lake Malawi, as well as peripheral...

Martinou, Wolfgang Nentwig, Jan Pergl, Petr Pyšek, Wolfgang Rabitsch, David M. Richardson, Helen E. Roy, Wolf-Christian Saul, Riccardo Scalera, Montserrat Vila, John R. U. Wilson, Sabina Kumschick & Sabrina Kumschick
Many alien taxa are known to cause socio-economic impacts by affecting the different constituents of human well-being (security; material and non-material assets; health; social, spiritual and cultural relations; freedom of choice and action). Attempts to quantify socio-economic impacts in monetary terms are unlikely to provide a useful basis for evaluating and comparing impacts of alien taxa because they are notoriously difficult to measure and important aspects of human well-being are ignored. Here, we propose a...
