Data from: Social conformity and propagation of information in collective u-turns of fish schools

Valentin Lecheval, Li Jiang, Pierre Tichit, Clément Sire, Charlotte K. Hemelrijk & Guy Theraulaz
Moving animal groups such as schools of fish or flocks of birds often undergo sudden collective changes of their travelling direction as a consequence of stochastic fluctuations in heading of the individuals. However, the mechanisms by which these behavioural fluctuations arise at the individual level and propagate within a group are still unclear. In the present study, we combine an experimental and theoretical approach to investigate spontaneous collective U-turns in groups of rummy-nose tetra (Hemigrammus...

Data from: Body stores persist as fitness correlate in a long-distance migrant released from food constraints

Adriaan M. Dokter, Wimke Fokkema, Steven K. Bekker, Willem Bouten, Barwoldt S. Ebbinge, Gerard Müskens, Han Olff, Henk P. Van Der Jeugd, Bart A. Nolet & Barwolt S Ebbinge
Long-distance migratory birds rely on acquisition of body reserves to fuel their migration and reproduction. Breeding success depends on the amount of body reserve acquired prior to migration, which is thought to increase with access to food at the fuelling site. Here we studied how food abundance during fuelling affected time budgets and reproductive success. In a regime of plenty, we expected that (1) limitations on food harvesting would become lifted, allowing birds to frequently...

Data from: Nest survival in year-round breeding tropical Red-capped Larks (Calandrella cinerea) increases with higher nest abundance but decreases with higher invertebrate availability and rainfall

Joseph Mwangi, Henry K. Ndithia, Rosemarie Kentie, Muchane Muchai & B. Irene Tieleman
Nest survival is critical to breeding in birds and plays an important role in life-history evolution and population dynamics. Studies evaluating the proximate factors involved in explaining nest survival and the resulting temporal patterns are biased in favor of temperate regions. Yet, such studies are especially pertinent to the tropics, where nest predation rates are typically high and environmental conditions often allow for year-round breeding. To tease apart the effects of calendar month and year,...

Data from: Diet and provisioning rate differ predictably between dispersing and philopatric pied flycatchers

Marion Nicolaus, Solange C.Y. Barrault, Christiaan Both & Solange C Y Barrault
Dispersal is an essential process for most animal populations to persist in changing environments. Dispersers are often a non-random sample of the population, and differ consistently from non-dispersers in a suite of correlated phenotypic traits (‘dispersal syndromes’). This phenotypic integration is thought to be adaptive. Here, we investigate whether dispersal tendency of individual pied flycatchers (Ficedula hypoleuca) covaries with a set of repeatable behaviors that should confer advantages for surviving and reproducing in novel environments....

Data from: Epigenetic mapping of the Arabidopsis metabolome reveals mediators of the epigenotype-phenotype map

Rik Kooke, Lionel Morgado, Frank FM Becker, Henriette Van Eekelen, Rashmi Hazarika, Qunfeng F Zheng, Ric CH De Vos, Frank Johannes & Joost JB Keurentjes
Identifying the sources of natural variation underlying metabolic differences between plants will enable a better understanding of plant metabolism and provide insights into the regulatory networks that govern plant growth and morphology. So far, however, the contribution of epigenetic variation to metabolic diversity has been largely ignored. In the present study, we utilized a panel of Arabidopsis thaliana epigenetic recombinant inbred lines (epiRILs) to assess the impact of epigenetic variation on the metabolic composition. Thirty...

Data from: Body mass as a supertrait linked to abundance and behavioural dominance in hummingbirds: a phylogenetic approach

Rafael Bribiesca, Leonel Herrera-Alsina, Eduardo Ruiz-Sanchez, Luis A. Sánchez-González & Jorge E. Schondube
Body mass has been considered one of the most critical organismal traits, and its role in many ecological processes has been widely studied. In hummingbirds body mass has been linked to ecological features like foraging performance, metabolic rates, and cost of flying, among others. We used an evolutionary approach to test if body mass is a good predictor of two of the main ecological features of hummingbirds: their abundances and behavioural dominance. To determine whether...

Data from: Early-life telomere length predicts lifespan and lifetime reproductive success in a wild bird

Justin R. Eastwood, Michelle L. Hall, Niki Teunissen, Sjouke A. Kingma, Nataly Hidalgo Aranzamendi, Marie Fan, Michael Roast, Simon Verhulst & Anne Peters
Poor conditions during early development can initiate trade-offs that favour current survival at the expense of somatic maintenance and subsequently, future reproduction. However, the mechanisms that link early and late life-history are largely unknown. Recently it has been suggested that telomeres, the nucleoprotein structures at the terminal end of chromosomes, could link early-life conditions to lifespan and fitness. In wild purple-crowned fairy-wrens, we combined measurements of nestling telomere length (TL) with detailed life-history data to...

Data from: Rapid divergence of genome architectures following the origin of an ectomycorrhizal symbiosis in the genus Amanita

Jaqueline Hess, Inger Skrede, Maryam Chaib De Mares, Matthieu Hainaut, Bernard Henrissat & Anne Pringle
Fungi are evolutionary shape shifters and adapt quickly to new environments. Ectomycorrhizal (EM) symbioses are mutualistic associations between fungi and plants and have evolved repeatedly and independently across the fungal tree of life, suggesting lineages frequently reconfigure genome content to take advantage of open ecological niches. To date analyses of genomic mechanisms facilitating EM symbioses have involved comparisons of distantly related species, but here, we use the genomes of three EM and two asymbiotic (AS)...

Data from: Agricultural pastures challenge the attractiveness of natural saltmarsh for a migratory goose

Adriaan M. Dokter, Wimke Fokkema, Barwolt S. Ebbinge, Han Olff, Henk P. Van Der Jeugd & Bart A. Nolet
1. Broad-scale land conversions and fertilizer use have dramatically altered the available staging area for herbivorous long-distance migrants. Instead of natural land, these birds rely increasingly on pastures for migratory fuelling and stopover, often conflicting with farming practices. To be able to predict and manage birds’ future habitat use, the relative advantages and disadvantages of natural (e.g. saltmarsh, intertidal) versus anthropogenic staging sites for foraging need to be understood. 2. We compared the migratory staging...

Data from: Density-dependent positive feedbacks buffer aquatic plants from interactive effects of eutrophication and predator loss

Serena Donadi, Åsa N. Austin, Elvira Svartgren, Britas Klemens Eriksson, Joakim P. Hansen & Johan S. Eklöf
Self-facilitation allows populations to persist under disturbance by ameliorating experienced stress. In coastal ecosystems, eutrophication and declines of large predatory fish are two common disturbances that can synergistically impact habitat-forming plants by benefitting ephemeral algae. In theory, density-dependent intra-specific plant facilitation could weaken such effects, by ameliorating the amount of experienced stress. Here, we tested if and how shoot density of a common aquatic plant (Myriophyllum spicatum) alters the response of individual plants to eutrophication...

Data from: Reciprocal facilitation between large herbivores and ants in a semi-arid grassland

Xiaofei Li, Zhiwei Zhong, Dirk Sanders, Chris Smit, Deli Wang, Petri Nummi, Yu Zhu, Ling Wang, Hui Zhu, Nazim Hassan & Christian Smit
While positive interactions have been well documented in plant and sessile benthic marine communities, their role in structuring mobile animal communities and underlying mechanisms has been less explored. Using field removal experiments, we demonstrated that a large vertebrate herbivore (cattle; Bos tarurs) and a much smaller invertebrate (ants; Lasius spp.), the two dominant animal taxa in a semi-arid grassland in Northeast China, facilitate each other. Cattle grazing led to higher ant mound abundance compared to...

Data from: Silver spoon effects of hatching order in an asynchronous hatching bird

Zitan Song, Yuqi Zou, Canshi Hu, Yuanxing Ye, Chao Wang, Baoping Qing, Jan Komdeur & Changqing Ding
The silver spoon hypothesis proposes that individuals which develop under favourable conditions will gain fitness benefits throughout their lifetime. Hatching order may create a considerable size hierarchy within a brood and lead to earlier-hatched nestlings having a competitive advantage over their siblings, which has been illustrated in some studies. However, there have been few explorations into the effect on subsequent generations. Here, using a 15-year-long study, we investigated the long-term fitness consequence of hatching order...

Data from: Diversity in form and function: vertical distribution of soil fauna mediates multidimensional trait variation

Jacintha Ellers, Matty P. Berg, André T.C. Dias, Simone Fontana, Astra Ooms & Marco Moretti
1. It has been widely recognized that species show extensive variation in form and function. Based on species’ attributes they can be positioned along major axes of variation, which are often defined by life history traits, such as number of offspring, age at maturity or generation time. Less emphasis has been given in this respect to tolerance traits, especially to resistance to abiotic stress conditions, which often determine community (dis)assembly and distribution. 2. Soil fauna...

Data from: Seasonal differences in baseline innate immune function are better explained by environment than annual cycle stage in a year-round breeding tropical songbird

Chima J. Nwaogu, Will Cresswell, Maaike A. Versteegh & B. Irene Tieleman
1. Seasonal variation in innate immunity is often attributed to either temporal environmental variation or to life history trade-offs that arise from specific annual cycle stages but decoupling them is difficult in natural populations. 2. Here, we effectively decouple seasonal environmental variation from annual cycle stage effects by exploiting cross-seasonal breeding and moult in the tropical Common Bulbul Pycnonotus barbatus. We test how annual cycle stage interacts with a key seasonal environmental variable, rainfall, to...

Data from: Detecting the dependence of diversification on multiple traits from phylogenetic trees and trait data

Leonel Herrera-Alsina, Paul Van Els & Rampal S. Etienne
Species diversification may be determined by many different variables, including the traits of the diversifying lineages. The State-dependent Speciation and Extinction (SSE) framework contains methods to detect the dependence of diversification on these traits. For the analysis of traits with multiple states, MuSSE (Multiple-States dependent Speciation and Extinction) was developed. However, MuSSE and other state-dependent speciation and extinction models have been shown to yield false positives, because they cannot separate differential diversification rates from dependence...

Data from: Nonadditive effects of consumption in an intertidal macroinvertebrate community are independent of food availability but driven by complementarity effects

Emily M. Van Egmond, Peter M. Van Bodegom, Jurgen R. Van Hal, Richard S.P. Van Logtestijn, Matty P. Berg, Rien Aerts & Richard S. P. Van Logtestijn
Suboptimal environmental conditions are ubiquitous in nature and commonly drive the outcome of biological interactions in community processes. Despite the importance of biological interactions for community processes, knowledge on how species interactions are affected by a limiting resource, e.g. low food availability, remains limited. Here, we tested whether variation in food supply causes non-additive consumption patterns, using the macroinvertebrate community of intertidal sandy beaches as a model system. We quantified isotopically labelled diatom consumption by...

Data from: Reduced telomere length in offspring of old fathers in a long-lived seabird

Sandra Bouwhuis, Simon Verhulst, Christina Bauch & Oscar Vedder
Evidence for transgenerational effects of senescence, whereby offspring from older parents have a reduced lifetime reproductive success, is increasing. Such effects could arise from compromised germline maintenance in old parents, potentially reflected in reduced telomere length in their offspring. We test the relationship between parental age and offspring early-life telomere length in a natural population of common terns and find a significant negative correlation between paternal age and offspring telomere length. Offspring telomere length is...

Data from: Reproductive effort and future parental competitive ability: a nest box removal experiment

Rienk W. Fokkema, Richard Ubels, Christiaan Both, Livia De Felici & Joost M. Tinbergen
The life history trade-off between current- and future reproduction is a theoretically well-established concept. However, empirical evidence for the occurrence of a fitness cost of reproduction is mixed. Evidence indicates that parents only pay a cost of reproduction when local competition is high. In line with this, recent experimental work on a small passerine bird, the Great tit (Parus major) showed that reproductive effort negatively affected the competitive ability of parents, estimated through competition for...

Data from: Subordinate females in the cooperatively breeding Seychelles warbler obtain direct benefits by joining unrelated groups

Frank Groenewoud, Sjouke A. Kingma, Martijn Hammers, Hannah L. Dugdale, Terry Burke, David S. Richardson & Jan Komdeur
1. In many cooperatively breeding animals, a combination of ecological constraints and benefits of philopatry favours offspring taking a subordinate position on the natal territory instead of dispersing to breed independently. However, in many species individuals disperse to a subordinate position in a non-natal group (“subordinate between-group” dispersal), despite losing the kin-selected and nepotistic benefits of remaining in the natal group. It is unclear which social, genetic and ecological factors drive between-group dispersal. 2. We...

Data from: Generational shift in spring staging site use by a long-distance migratory bird

Mo A. Verhoeven, Jelle A.H. Loonstra, Jos C.E.W. Hooijmeijer, Jose A. Masero, Theunis Piersma, Nathan R. Senner, Jos C. E. W. Hooijmeijer & A. H. Jelle Loonstra
In response to environmental change, species have been observed altering their migratory behaviours. Few studies, however, have been able to determine whether these alterations resulted from inherited, plastic, or flexible changes. Here we present a unique observation of a rapid population-level shift in migratory routes — over 300 km from Spain to Portugal — by continental black-tailed godwits Limosa limosa limosa. This shift did not result from adult godwits changing staging sites, as adult site...

Data from: Long-lived rodents reveal signatures of positive selection in genes associated with lifespan

Arne Sahm, Martin Bens, Karol Szafranski, Susanne Holtze, Marco Groth, Matthias Görlach, Cornelis Calkhoven, Christine Müller, Matthias Schwab, Johann Kraus, Hans Armin Kestler, Alessandro Cellerino, Hynek Burda, Thomas Hildebrandt, Philip Dammann & Matthias Platzer
The genetics of lifespan determination is poorly understood. Most research has been done on short-lived animals and it is unclear if these insights can be transferred to long-lived mammals like humans. Some African mole-rats (Bathyergidae) have life expectancies that are multiple times higher than similar sized and phylogenetically closely related rodents. To gain new insights into genetic mechanisms determining mammalian lifespans, we obtained genomic and transcriptomic data from 17 rodent species and scanned eleven evolutionary...

Data from: Detecting local diversity-dependence in diversification

Liang Xu & Rampal S. Etienne
Whether there are ecological limits to species diversification is a hotly debated topic. Molecular phylogenies show slowdowns in lineage accumulation, suggesting that speciation rates decline with increasing diversity. A maximum likelihood method to detect diversity-dependent diversification from phylogenetic branching times exists, but it assumes that diversity-dependence is a global phenomenon and therefore ignores that the underlying species interactions are mostly local, and not all species in the phylogeny co-occur locally. Here, we explore whether this...

Data from: From ornament to armament or loss of function? Breeding plumage acquisition in a genetically monogamous bird

Marie Fan, Niki Teunissen, Michelle L. Hall, Nataly Hidalgo Aranzamendi, Sjouke A. Kingma, Michael Roast, Kaspar Delhey & Anne Peters
1. The evolution of conspicuous male traits is thought to be driven by female mate choice or male-male competition. These two mechanisms are often viewed as distinct processes, with most studies focusing on female choice. 2. However, both mechanisms of sexual selection can act simultaneously on the same trait (i.e. dual function) and/or interact in a synergistic or conflicting way. Dual function-traits are commonly assumed to originate through male-male competition before being used in female...

Data from: Contrasting heterozygosity-fitness correlations across life in a long-lived seabird

Coraline Bichet, Oscar Vedder, Hedwig Sauer-Gürth, Peter H. Becker, Michael Wink & Sandra Bouwhuis
Selection is a central force underlying evolutionary change and can vary in strength and direction, for example across time and space. The fitness consequences of individual genetic diversity have often been investigated by testing for multi-locus heterozygosity-fitness correlations (HFCs), but few studies have been able to assess HFCs across life stages and in both sexes. Here, we test for HFCs using a 26-year longitudinal individual-based dataset from a large population of a long-lived seabird (the...

Data from: Canalisation in the wild: effects of developmental conditions on physiological traits are inversely linked to their association with fitness

Jelle J. Boonekamp, Ellis Mulder & Simon Verhulst
Ecological conditions affect fitness, but mechanisms causing such effects are not well known, while evolved responses to environmental variation may depend on the underlying mechanisms. Consequences of environmental conditions vary strongly between traits, but a framework to interpret such variation is lacking. We propose that variation in trait response may be explained by differential canalisation, with traits with larger fitness effects showing weaker responses to environmental perturbations due to preferential resource allocation to such traits....
