Data from: Early to rise, early to breed: a role for daily rhythms in seasonal reproduction

Jessica L. Graham, Natalie J. Cook, Katie B. Needham, Michaela Hau & Timothy J. Greives
Vertebrates use environmental cues to time reproduction to optimal breeding conditions. Numerous laboratory studies have revealed that light experienced during a critical window of the circadian (daily) rhythm can influence reproductive physiology. However, whether these relationships observed in captivity hold true under natural conditions and how they relate to observed variation in timing of reproductive output remains largely unexplored. Here we test the hypothesis that individual variation in daily timing recorded in nature (i.e. chronotype)...

Data from: Heart rate reveals torpor at high body temperatures in lowland tropical free-tailed bats

M. Teague O'Mara, Sebastian Rikker, Martin Wikelski, Andries Ter Maat, Henry S. Pollock & Dina K. N. Dechmann
Reduction in metabolic rate and body temperature is a common strategy for small endotherms to save energy. The daily reduction in metabolic rate and heterothermy, or torpor, is particularly pronounced in regions with a large variation in daily ambient temperature. This applies most strongly in temperate bat species (order Chiroptera), but it is less clear how tropical bats save energy if ambient temperatures remain high. However, many subtropical and tropical species use some daily heterothermy...

Data from: Individual recognition of opposite sex vocalizations in the zebra finch

Pietro B. D'Amelio, Milena Klumb, Mauricio Nicolas Adreani, Manfred Gahr & Andries Ter Maat
Individual vocal recognition plays an important role in the social lives of many vocally active species. In group-living songbirds the most common vocalizations during communal interactions are low-intensity, soft, unlearned calls. Being able to tell individuals apart solely from a short call would allow a sender to choose a specific group member to address, resulting in the possibility to form complex communication networks. However, little research has yet been carried out to discover whether soft...

Data from: Heritability and social brood effects on personality in juvenile and adult life-history stages in a wild passerine

Isabel S. Winney, Julia Schroeder, Shinichi Nakagawa, Yu-Hsun Hsu, Mirre J. Simons, Alfredo Sánchez-Tójar, Maria-Elena Mannarelli & Terry Burke
How has evolution led to the variation in behavioural phenotypes (personalities) in a population? Knowledge of whether personality is heritable, and to what degree it is influenced by the social environment, is crucial to understanding its evolutionary significance, yet few estimates are available from natural populations. We tracked three behavioural traits during different life-history stages in a pedigreed population of wild house sparrows. Using a quantitative genetic approach, we demonstrated heritability in adult exploration, and...

Data from: Behavioural mediators of genetic life-history trade-offs: a test of the pace-of-life syndrome hypothesis in field crickets

Francesca Santostefano, Alastair J. Wilson, Petri T. Niemela & Niels J. Dingemanse
The pace-of-life syndrome (POLS) hypothesis predicts associations between life-history and ‘risky’ behaviours. Individuals with ‘fast’ lifestyles should develop faster, reproduce earlier, exhibit more risk-prone behaviour, and die sooner than those with ‘slow’ lifestyles. While support for POLS has been equivocal to date, studies have relied on individual-level (phenotypic) patterns in which genetic trade-offs may be masked by environmental effects on phenotypes. We estimated genetic correlations between life-history (development, lifespan, size) and risky behaviours (exploration, aggression)...

Data from: Lateralized feeding behavior is associated with asymmetrical neuroanatomy and lateralized gene expressions in the brain in scale-eating cichlid fish

Hyuk Je Lee, Ralf F. Schneider, Tereza Manousaki, Ji Hyoun Kang, Etienne Lein, Paolo Franchini & Axel Meyer
Lateralized behavior (‘handedness’) is unusual, but consistently found across diverse animal lineages, including humans. It is thought to reflect brain anatomical and/or functional asymmetries, but its neuro-molecular mechanisms remain largely unknown. Lake Tanganyika scale-eating cichlid fish, Perissodus microlepis show pronounced asymmetry in their jaw morphology as well as handedness in feeding behavior – feeding scales preferentially only from one or the other side of their victims. This makes them an ideal model in which to...

Data from: Age-dependent trajectories differ between within-pair and extra-pair paternity success

Yu-Hsun Hsu, Mirre J. P. Simons, Julia Schroeder, Antje Girndt, Isabel S. Winney, Terry Burke, Shinichi Nakagawa & Y.-H. Hsu
Reproductive success is associated with age in many taxa, increasing in early life followed by reproductive senescence. In socially monogamous, but genetically polygamous species, this generates the interesting possibility of differential trajectories of within-pair and extra-pair siring success with age in males. We investigate these relationships simultaneously using within-individual analyses with 13 years of data from an insular house sparrow (Passer domesticus) population. As expected, we found that both within- and extra-pair paternity success increased...

Data from: Testing the phenotype-linked fertility hypothesis in the presence and absence of inbreeding

Wolfgang Forstmeier, Malika Ihle, Pavlina Opatova, Katrin Martin, Ulrich Knief, Jana Albrechtová, Tomas Albrecht & Bart Kempenaers
The phenotype-linked fertility hypothesis suggests that females can judge male fertility by inspecting male phenotypic traits. This is because male sexually selected traits might correlate with sperm quality if both are sensitive to factors that influence male condition. A recent meta-analysis found little support for this hypothesis, suggesting little or no shared condition dependence. However, we recently reported that in captive zebra finches (Taeniopygia guttata) inbreeding had detrimental effects both on phenotypic traits and on...

Data from: Methods in field chronobiology

Davide Michelangelo Dominoni, Susanne Åkesson, Raymond Klaassen, Kamiel Spoelstra & Martin Bulla
Chronobiological research has seen a continuous development of novel approaches and techniques to measure rhythmicity at different levels of biological organization from locomotor activity (e.g. migratory restlessness) to physiology (e.g. temperature and hormone rhythms, and relatively recently also in genes, proteins and metabolites). However, the methodological advancements in this field have been mostly and sometimes exclusively used only in indoor laboratory settings. In parallel, there has been an unprecedented and rapid improvement in our ability...

Data from: The curious case of Bradypus variegatus sloths: populations in threatened habitats are biodiversity components needing protection

Sofia Marques Silva, José A. Dávila, Bryson Voirin, Susana Lopes, Nuno Ferrand & Nadia Moraes-Barros
Studying Neotropical wild populations is of particular interest. While this region is facing an escalating habitat degradation, it also has remarkable biodiversity levels, whose origin we are only beginning to understand. A myriad of processes might have had idiosyncratic effects on its numerous species. Within the hottest Neotropical biodiversity hotspot, the Atlantic Forest (AF), species and genetic diversities are organized latitudinally, with decreasing diversity levels southwards. Bradypus variegatus, the brown-throated three-toed sloth, was one of...

Data from: Animal tracking meets migration genomics: transcriptomic analysis of a partially migratory bird species

Paolo Franchini, Iker Irisarri, Adam Fudickar, Andreas Schmidt, Axel Meyer, Martin Wikelski & Jesko Partecke
Seasonal migration is a widespread phenomenon, which is found in many different lineages of animals. This spectacular behaviour allows animals to avoid seasonally adverse environmental conditions to exploit more favourable habitats. Migration has been intensively studied in birds, which display astonishing variation in migration strategies, thus providing a powerful system for studying the ecological and evolutionary processes that shape migratory behaviour. Despite intensive research, the genetic basis of migration remains largely unknown. Here we used...

Data from: Variation in fine-scale genetic structure and local dispersal patterns between peripheral populations of a South American passerine bird

Esteban Botero-Delgadillo, Verónica Quirici, Yanina Poblete, Élfego Cuevas, Sylvia Kuhn, Alexander Girg, Kim Teltscher, Elie Poulin, Bart Kempenaers & Rodrigo A. Vasquez
The distribution of suitable habitat influences natal and breeding dispersal at small spatial scales, resulting in strong micro-geographic genetic structure. Although environmental variation can promote inter-population differences in dispersal behavior and local spatial patterns, the effects of distinct ecological conditions on within-species variation in dispersal strategies and in fine-scale genetic structure remain poorly understood. We studied local dispersal and fine-scale genetic structure in the thorn-tailed rayadito (Aphrastura spinicauda), a South American bird that breeds along...

Data from: Measurement artefacts lead to false positives in the study of birdsong in noise

Henrik Brumm, Sue Anne Zollinger, Petri T. Niemelä & Philipp Sprau
1: Numerous studies over the past decade have reported correlations between elevated levels of anthropogenic noise and a rise in the minimum frequency of acoustic signals of animals living in noisy habitats. This pattern appears to be occurring globally, and higher pitched signals have been hypothesized to be adaptive changes that reduce masking by low-frequency traffic noise. However, the sound analysis methods most often used in these studies are prone to measurement errors that can...

Data from: No mutual mate choice for quality in zebra finches: time to question a widely-held assumption

Daiping Wang, Wolfgang Forstmeier & Bart Kempenaers
Studies of mate choice typically assume that individuals prefer high quality mates and select them based on condition-dependent indicator traits. In species with bi-parental care, mutual mate choice is expected to result in assortative mating for quality. When assortment is not perfect, the lower quality pair members are expected to compensate by increased parental investment to secure their partner (positive differential allocation). This framework has been assumed to hold for monogamous species like the zebra...

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: Cyclic bouts of extreme bradycardia counteract the highmetabolism of frugivorous bats

M. Teague O'Mara, Martin Wikelski, Christian C. Voigt, Andries Ter Maat, Henry S. Pollock, Gary Burness, Lanna M. Desantis, Dina K. N. Dechmann & Dina KN Dechmann
Active flight requires the ability to efficiently fuel bursts of costly locomotion while maximizing energy conservation during non-flying times. We took a multi-faceted approach to estimate how fruit-eating bats (Uroderma bilobatum) manage a high-energy lifestyle fueled primarily by fig juice. Miniaturized heart rate telemetry shows that they use a novel, cyclic, bradycardic state that reduces daily energetic expenditure by 10% and counteracts heart rates as high as 900 bpm during flight. Uroderma bilobatum support flight...

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: Effects of experimental night lighting on the daily timing of winter foraging in common European songbirds

Arnaud Da Silva, David Diez-Méndez & Bart Kempenaers
The ecological effects of light pollution are becoming better understood, especially in birds. Recent studies have shown that several bird species can use street lighting to extend activity into the night during the breeding season. However, most of these studies are correlational and little is known about the effects of artificial night lighting on the timing of activities outside the breeding season. During winter, low temperatures and short days may limit foraging opportunities and can...

Data from: Vocal plasticity in mallards: multiple signal changes in noise and the evolution of the Lombard effect in birds

Adriana M. Dorado-Correa, Sue Anne Zollinger & Henrik Brumm
Signal plasticity is a building block of complex animal communication systems. A particular form of signal plasticity is the Lombard effect, in which a signaler increases its vocal amplitude in response to an increase in the background noise. The Lombard effect is a basic mechanism for communication in noise that is well-studied in human speech and which has also been reported in other mammals and several bird species. Sometimes, but not always, the Lombard effect...

Data from: Simulated moult reduces flight performance but overlap with breeding does not affect breeding success in a long-distance migrant

Barbara M. Tomotani, Florian T. Muijres, Julia Koelman, Stefania Casagrande & Marcel E. Visser
1. Long-distance migrants are time-constrained as they need to incorporate many annual cycle stages within a year. Migratory passerines moult in the short interval between breeding and migration. To widen this interval, moult may start while still breeding, but this results in flying with moulting wings when food provisioning. 2. We experimentally simulated wing gaps in breeding male pied flycatchers by plucking 2 primary feathers from both wings. We quantified the nest visitations of both...

Data from: Routine habitat switching alters the likelihood and persistence of infection with a pathogenic parasite

David R. Daversa, Andrea Manica, Jaime Bosch, Jolle W. Jolles & Trenton W. J. Garner
1.Animals switch habitats on a regular basis, and when habitats vary in suitability for parasitism, routine habitat switching alters the frequency of parasite exposure and may affect post-infection parasite proliferation. However, the effects of routine habitat switching on infection dynamics are not well understood. 2.We performed infection experiments, behavioural observations, and field surveillance to evaluate how routine habitat switching by adult alpine newts (Ichthyosaura alpestris) influences infection dynamics of the pathogenic parasite, Batrachochytrium dendrobatidis (Bd)....

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: Plumage color manipulation has no effect on social dominance or fitness in zebra finches

Sofia Jerónimo, Mehdi Khadraoui, Daiping Wang, Katrin Martin, John A. Lesku, Kylie A. Robert, Emmi Schlicht, Wolfgang Forstmeier & Bart Kempenaers
Colourful plumage ornaments may evolve because they play a role in mate choice or in intrasexual competition, acting as signals of species identity or of individual quality. The zebra finch (Taeniopygia guttata) is a model organism for the study of mate choice and its colourful plumage ornaments are thought to be used in both of these contexts. Numerous genetic colour variants have been described for this species, but they are rare in the wild. This...

Data from: Polygamy slows down population divergence in shorebirds

Josephine D'Urban Jackson, Natalie Dos Remedios, Kathryn H. Maher, Sama Zefania, Susan Haig, Sara Oyler-McCance, Donald Blomqvist, Terry Burke, Mike W. Bruford, Tamas Szekely, Clemens Küpper & Michael W. Bruford
Sexual selection may act as a promotor of speciation since divergent mate choice and competition for mates can rapidly lead to reproductive isolation. Alternatively, sexual selection may also retard speciation since polygamous individuals can access additional mates by increased breeding dispersal. High breeding dispersal should hence increase gene flow and reduce diversification in polygamous species. Here we test how polygamy predicts diversification in shorebirds using genetic differentiation and subspecies richness as proxies for population divergence....

Data from: Singing from North to South: latitudinal variation in timing of dawn singing under natural and artificial light conditions

Arnaud Da Silva & Bart Kempenaers
1. Animals breeding at northern latitudes experience drastic changes in daily light conditions during the breeding season with decreasing periods of darkness, whereas those living at lower latitudes are exposed to naturally dark nights throughout the year. Nowadays, many animals are also exposed to artificial night lighting (often referred to as light pollution). 2. Animals strongly rely on variation in light levels to time their daily and seasonal behaviour. Previous work on passerine birds showed...
