Data from: Repeatable and heritable behavioural variation in a wild cooperative breeder

Hannah A. Edwards, Terry Burke & Hannah L. Dugdale
Quantifying consistent differences in behaviour among individuals is vital to understanding the ecological and evolutionary significance of animal personality. To quantify personality, the phenotypic variation of a behavioural trait is partitioned to assess how it varies among individuals, which is also known as repeatability. If pedigree data are available, the phenotypic variation can then be further partitioned to estimate the additive genetic variance and heritability. Assessing the repeatability and heritability of personality traits therefore allows...

Data from: Patterns of divergence across the geographic and genomic landscape of a butterfly hybrid zone associated with a climatic gradient

Sean F. Ryan, Michaël C. Fontaine, J. Mark Scriber, Michael E. Pfrender, Shawn T. O'Neil & Jessica J. Hellmann
Hybrid zones are a valuable tool for studying the process of speciation and for identifying the genomic regions undergoing divergence and the ecological (extrinsic) and non-ecological (intrinsic) factors involved. Here, we explored the genomic and geographic landscape of divergence in a hybrid zone between Papilio glaucus and Papilio canadensis. Using a genome scan of 28,417 ddRAD SNPs, we identified genomic regions under possible selection and examined their distribution in the context of previously identified candidate...

Data from: No phenotypic plasticity in nest-site selection in response to extreme flooding events

Liam D. Bailey, Bruno Ens, Christiaan Both, Dik Heg, Kees Oosterbeek & Martijn Van De Pol
Phenotypic plasticity is a crucial mechanism for responding to changes in climatic means, yet we know little about its role in responding to extreme climatic events (ECEs). ECEs may lack the reliable cues necessary for phenotypic plasticity to evolve; however, this has not been empirically tested. We investigated whether behavioural plasticity in nest-site selection allows a long-lived shorebird (Haematopus ostralegus) to respond to flooding. We collected longitudinal nest elevation data on individuals over two decades,...

Data from: No fitness benefits of early molt in a fairy-wren: relaxed sexual selection under genetic monogamy?

Marie Fan, Michelle L. Hall, Sjouke A. Kingma, Lisa M. Mandeltort, Nataly Hidalgo Aranzamendi, Kaspar Delhey & Anne Peters
The evolution of male ornamentation has long been the focus of sexual selection studies. However, evidence is accumulating that sexually selected traits can also be lost, although the process is ill-understood. In male fairy-wrens (Malurus spp.), early molt into the seasonal breeding plumage is critical for obtaining extra-pair paternity (EPP), which reaches very high levels in these socially monogamous songbirds. A notable exception is the purple-crowned fairy-wren, Malurus coronatus, which, like its congeners, breeds cooperatively,...

Data from: Oxidative status and fitness components in the Seychelles warbler

Janske Van De Crommenacker, Martijn Hammers, Jildou Van Der Woude, Marina Louter, Peter Santema, David S. Richardson & Jan Komdeur
Oxidative damage, caused by reactive oxygen species during aerobic respiration, is thought to be an important mediator of life-history trade-offs. To mitigate oxidative damage, antioxidant defence mechanisms are deployed, often at the cost of resource allocation to other body functions. Both reduced resource allocation to body functions and direct oxidative damage may decrease individual fitness, through reducing survival and/or reproductive output. The oxidative costs of reproduction have gained much attention recently, but few studies have...

Data from: Biodiversity change is uncoupled from species richness trends: consequences for conservation and monitoring

Helmut Hillebrand, Bernd Blasius, Elizabeth T. Borer, Jonathan M. Chase, John Downing, Britas Klemens Eriksson, Christopher T. Filstrup, W. Stanley Harpole, Dorothee Hodapp, Stefano Larsen, Aleksandra M. Lewandowska, Eric W. Seabloom, Dedmer B. Van De Waal, Alexey B. Ryabov & John A. Downing
1. Global concern about human impact on biological diversity has triggered an intense research agenda on drivers and consequences of biodiversity change in parallel with international policy seeking to conserve biodiversity and associated ecosystem functions. Quantifying the trends in biodiversity is far from trivial, however, as recently documented by meta-analyses which report little if any net change of local species richness through time. 2. Here, we summarize several limitations of species richness as a metric...

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: Form–function relationships in a marine foundation species depend on scale: a shoot to global perspective from a distributed ecological experiment

Jennifer L. Ruesink, John J. Stachowicz, Pamela L. Reynolds, Christoffer Boström, Mathieu Cusson, James Douglass, Johan Eklöf, Aschwin H. Engelen, Masakazu Hori, Kevin Hovel, Katrin Iken, Per-Olav Moksnes, Masahiro Nakaoka, Mary I. O'Connor, Jeanine L. Olsen, Erik E. Sotka, Matthew A. Whalen & Emmett J. Duffy
Form-function relationships in plants underlie their ecosystem roles in supporting higher trophic levels through primary production, detrital pathways, and habitat provision. For widespread, phenotypically-variable plants, productivity may differ not only across abiotic conditions, but also from distinct morphological or demographic traits. A single foundation species, eelgrass (Zostera marina), typically dominates north temperate seagrass meadows, which we studied across 14 sites spanning 32-61° N latitude and two ocean basins. Body size varied by nearly two orders...

Data from: Seascape genetics and biophysical connectivity modelling support conservation of the seagrass Zostera marina in the Skagerrak-Kattegat region of the eastern North Sea

Marlene Jahnke, Per R. Jonsson, Per-Olav Moksnes, Lars-Ove Loo, Martin Nilsson Jacobi & Jeanine L. Olsen
Maintaining and enabling evolutionary processes within meta-populations is critical to resistance, resilience and adaptive potential. Knowledge about which populations act as sources or sinks, and the direction of gene flow, can help to focus conservation efforts more effectively and forecast how populations might respond to future anthropogenic and environmental pressures. As a foundation species and habitat provider, Zostera marina (eelgrass) is of critical importance to ecosystem functions including fisheries. Here we estimate connectivity of Z....

Data from: ‘Same procedure as last year?' Repeatedly tracked swifts show individual consistency in migration pattern in successive years

Arndt H. J. Wellbrock, Christina Bauch, Jan Rozman & Klaudia Witte
Individual migration pattern during non-breeding season is still a black box in many migratory birds. However, knowledge on both individual level and population level in migration and overwintering is fundamental to understand the life cycle of these birds and the constraints affecting them. We showed in a highly aerial migrant, the common swift Apus apus, that repeatedly tracked birds breeding at one site in Germany used the same individual-specific migration routes and wintering areas in...

Data from: Competitor phenology as a social cue in breeding site selection

Jelmer M. Samplonius & Christiaan Both
1. Predicting habitat quality is a major challenge for animals selecting a breeding patch, because it affects reproductive success. Breeding site selection may be based on previous experience, or on social information from the density and success of competitors with an earlier phenology. 2. Variation in animal breeding phenology is often correlated with variation in habitat quality. Generally, animals breed earlier in high quality habitats that allow them to reach a nutritional threshold required for...

Data from: Shifts in hatch dates do not provide pied flycatchers with a rapid ontogenetic route to adjust offspring time schedules to climate change

Janne Ouwehand, Claudia Burger & Christiaan Both
1. Environments change rapidly, and it is unclear whether organisms with complex life-styles, such as avian migrants, are able to adjust sufficiently. For understanding human impacts on ecosystem functioning, it is crucial to understand how well, and by which mechanisms species are able to adapt. 2. To improve the understanding of migrants’ ability to adjust their annual timing to climate change, we investigated ontogenetic hatch date effects on adult spring migration timing and female egg...

Data from: Photoperiod at the larval stage sets the timing of entire annual program in an herbivorous insect

Lucia Salis, Erik Van Den Hoorn, Domien G. M. Beersma, Roelof A. Hut & Marcel E. Visser
To maximize their fitness, organisms need to synchronize their phenology with the seasonal variation in environmental conditions. Most phenological traits are affected by environmental abiotic cues such as photoperiod, temperature and rainfall. When individuals with complex life-cycles fail to match one of the stages with the favourable environment, these negative conditions experienced may lead to carry-over effects and, thus, influence fitness in subsequent stages. In the winter moth, an herbivorous insect with an annual life-cycle,...

Data from: A cross-scale trophic cascade from large predatory fish to algae in coastal ecosystems

Serena Donadi, Åsa N. Austin, Ulf Bergström, B. Klemens Eriksson, Joakim P. Hansen, Philip Jacobson, Göran Sundblad, Marin Van Regteren & Johan S. Eklöf
Trophic cascades occur in many ecosystems, but the factors regulating them are still elusive. We suggest that an overlooked factor is that trophic interactions (TIs) are often scale-dependent and possibly interact across spatial scales. To explore the role of spatial scale for trophic cascades, and particularly the occurrence of cross-scale interactions (CSIs), we collected and analysed food-web data from 139 stations across 32 bays in the Baltic Sea. We found evidence of a four-level trophic...

Data from: Maternal egg hormones in the mating context: the effect of pair personality

Suvi Ruuskanen, Ton G. G. Groothuis, Alexander T. Baugh, Sonja V. Schaper, Bonnie DeVries, Kees Van Oers & Bonnie De Vries
Animal personality traits emerge developmentally from the interaction of genetic and early environmental factors. Maternal hormones, such as androgens (testosterone, T and androstenedione, A4), transferred to embryos and egg yolks may simultaneously organize multiple behavioural and physiological traits. Whereas previous studies demonstrated an association between the mother's personality and yolk androgen levels, the independent effects of the male partner's personality and pair combination are unknown. We test this association using an ecological model species for...

Data from: Biotically driven vegetation mosaics in grazing ecosystems: the battle between bioturbation and biocompaction

Ruth A. Howison, Han Olff, Johan Van De Koppel & Christian Smit
Grazing ecosystems ranging from the arctic tundra to tropical savannas are often characterized by small-scale mosaics of herbivore-preferred and herbivore-avoided patches, promoting plant biodiversity and resilience. The three leading explanations for bistable patchiness in grazed ecosystems are: i) herbivore-driven nutrient cycling, ii) plant growth-water infiltration feedback under aridity, and iii) irreversible local herbivore-induced abiotic stress (topsoil erosion, salinity). However, these insufficiently explain the high temporal patch dynamics and wide-ranging distribution of grazing mosaics across productive...

Data from: Joint care can outweigh costs of nonkin competition in communal breeders

Kat Bebbington, Eleanor A. Fairfield, Lewis G. Spurgin, Sjouke Anne Kingma, Hannah Dugdale, Jan Komdeur & David S. Richardson
Competition between offspring can greatly influence offspring fitness and parental investment decisions, especially in communal breeders where unrelated competitors have less incentive to concede resources. Given the potential for escalated conflict, it remains unclear what mechanisms facilitate the evolution of communal breeding among unrelated females. Resolving this question requires simultaneous consideration of offspring in noncommunal and communal nurseries, but such comparisons are missing. In the Seychelles warbler Acrocephalus sechellensis, we compare nestling pairs from communal...

Data from: Genomics meets applied ecology: characterizing habitat quality for sloths in a tropical agroecosystem

Emily D. Fountain, Jung Koo Kang, Douglas J. Tempel, Per J. Palsbøll, Jonathan N. Pauli & M. Zachariah Peery
Understanding how habitat quality in heterogeneous landscapes governs the distribution and fitness of individuals is a fundamental aspect of ecology. While mean individual fitness is generally considered a key to assessing habitat quality, a comprehensive understanding of habitat quality in heterogeneous landscapes requires estimates of dispersal rates among habitat types. The increasing accessibility of genomic approaches, combined with field-based demographic methods, provides novel opportunities for incorporating dispersal estimation into assessments of habitat quality. In this...

Data from: An age-dependent fitness cost of migration? Old trans-Saharan migrating spoonbills breed later than those staying in Europe, and late breeders have lower recruitment

Tamar Lok, Linde Veldhoen, Otto Overdijk, Joost M. Tinbergen & Theunis Piersma
1.Migration is a widespread phenomenon in the animal kingdom. On the basis of the considerable variation that exists between and within species, and even within populations, we may be able to infer the (age- and sex-specific) ecological trade-offs and constraints moulding migration systems from assessments of fitness associated with migration and wintering in different areas. 2.During three consecutive breeding seasons, we compared the reproductive performance (timing of breeding, breeding success, chick body condition and post-fledging...

Data from: Male but not female zebra finches with high plasma corticosterone have lower survival

Blanca Jimeno, Michael Briga, Michaela Hau & Simon Verhulst
(1) The glucocorticoid axis is essential for coping with predictable and unpredictable environmental variation. Despite this vital function, attempts to link individual variation in the glucocorticoid axis to survival have yielded mixed results, which may be due to endocrine variation caused by uncontrolled variation in environment and life history traits such as reproductive effort. We therefore studied the link between the glucocorticoid axis and long-term survival using captive non-breeding zebra finches. (2) We quantified the...

Data from: Robustness of the approximate likelihood of the protracted speciation model

Camille A. Simonet, Raphaël Scherrer, Artur Rego-Costa, Rampal S. Etienne & C. Simonet
The protracted speciation model presents a realistic and parsimonious explanation for the observed slowdown in lineage accumulation through time, by accounting for the fact that speciation takes time. A method to compute the likelihood for this model given a phylogeny is available and allows estimation of its parameters (rate of initiation of speciation, rate of completion of speciation, and extinction rate) and statistical comparison of this model to other proposed models of diversification. However this...

Data from: Telomere attrition and growth: a life-history framework and case study in common terns

Oscar Vedder, Simon Verhulst, Christina Bauch & Sandra Bouwhuis
The relationship between growth and age-specific telomere length, as a proxy of somatic state, is increasingly investigated, but observed patterns vary and a predictive framework is lacking. We outline expectations based on the assumption that telomere maintenance is costly and argue that individual heterogeneity in resource acquisition is predicted to lead to positive covariance between growth and telomere length. However, canalization of resource allocation to the trait with a larger effect on fitness, rendering that...

Data from: Increasing the accuracy and precision of relative telomere length estimates by RT qPCR

Justin R. Eastwood, Ellis Mulder, Simon Verhulst & Anne Peters
Since attrition of telomeres, DNA caps that protect chromosome integrity, is accelerated by various forms of stress, telomere length (TL) has been proposed as an indicator of lifetime accumulated stress. In ecological studies it has been used to provide insights into aging, life-history trade-offs, the costs of reproduction and disease. qPCR is a high throughput and cost effective tool to measure relative TL (rTL) that can be applied to newly-collected and archived ecological samples. However,...

Data from: The evolution of costly mate choice against segregation distorters

Andri Manser, Anna K. Lindholm, Franjo J. Weissing & Franz J. Weissing
The evolution of female preference for male genetic quality remains a controversial topic in sexual selection research. One well-known problem, known as the lek paradox, lies in understanding how variation in genetic quality is maintained in spite of natural selection and sexual selection against low-quality alleles. Here, we theoretically investigate a scenario where females pay a direct fitness cost to avoid males carrying an autosomal segregation distorter. We show that preference evolution is greatly facilitated...
