Individual variation in age-dependent reproduction: fast explorers live fast but senesce young?

Niels Dingemanse, Maria Moiron, Yimen G. Araya-Ajoy, Alexia Mouchet & Robin N. Abbey-Lee
1. Adaptive integration of life history and behaviour is expected to result in variation in the pace-of-life. Previous work focused on whether “risky” phenotypes live-fast-but-die-young, but reported conflicting support. We posit that individuals exhibiting risky phenotypes may alternatively invest heavily in early-life reproduction but consequently suffer greater reproductive senescence. 2. We used a 7-year longitudinal dataset with >1200 breeding records of >800 female great tits assayed annually for exploratory behaviour to test whether within-individual age-dependency...

Data from: Fur seal microbiota are shaped by the social and physical environment, show mother-offspring similarities and are associated with host genetic quality

Stefanie Grosser, Jan Sauer, Anneke Paijmans, Barbara Caspers, Jaume Forcada, Jochen Wolf & Joseph Hoffman
Despite an increasing appreciation of the importance of host-microbe interactions in ecological and evolutionary processes, the factors shaping microbial communities in wild populations remain poorly understood. We therefore exploited a natural experiment provided by two adjacent Antarctic fur seal (Arctocephalus gazella) colonies of high and low social density and combined 16S rRNA metabarcoding with microsatellite profiling of mother-offspring pairs to investigate environmental and genetic influences on skin microbial communities. Seal-associated bacterial communities differed profoundly between...

Data from: Scrutinizing assortative mating in birds

Daiping Wang, Wolfgang Forstmeier, Mihai Valcu, Niels Dingemanse, Martin Bulla, Christiaan Both, Renée A. Duckworth, Lynna Marie Kiere, Patrik Karell, Tomáš Albrecht & Bart Kempenaers
It is often claimed that pair bonds preferentially form between individuals that resemble one another. Such assortative mating appears to be widespread throughout the animal kingdom. Yet it is unclear whether the apparent ubiquity of assortative mating arises primarily from mate choice (‘like attracts like’) which can be constrained by same-sex competition for mates, from spatial or temporal separation, or from observer, reporting, publication or search bias. Here, based on a conventional literature search, we...

Data from: Sequential horizontal gene transfers from different hosts in a widespread Eurasian parasitic plant, Cynomorium coccineum

Natalie Cusimano & Susanne S. Renner
Premise of the study: Parasites with large geographic ranges, and different hosts in parts of their range, might acquire horizontally-transferred genes (HGTs), which might sometimes leave a footprint of gradual host and range expansion. Cynomorium coccineum, the only member of the Saxifragales family Cynomoriaceae, is a root holoparasite that occurs in water-stressed habitats from western China to the Canary Islands. It parasitizes at least ten angiosperm families from different orders, some of them only in...

Data from: The impact of pathological high-frequency oscillations on hippocampal network activity in rats with chronic epilepsy

Laura A. Ewell, Kyle B. Fischer, Christian Leibold, Stefan Leutgeb & Jill K. Leutgeb
In epilepsy, brain networks generate pathological high-frequency oscillations (pHFOs) during interictal periods. To understand how pHFOs differ from normal oscillations in overlapping frequency bands and potentially perturb hippocampal processing, we performed high-density single unit and local field potential recordings from hippocampi of behaving rats with and without chronic epilepsy. In epileptic animals, we observed two types of co-occurring fast oscillations, which by comparison to control animals we could classify as ‘ripple-like’ or ‘pHFO’. We compared...

Data from: Enough for all: no mating effort adjustment to varying mate availability in a gift-giving spider

Martina Magris & Cristina Tuni
Reproduction is costly and since males possess a finite energetic budget, resource allocation to one mating event may constrain investment in subsequent matings. Consequently, males of many species evolved to adjust their reproductive investment in response to mating opportunities. When female availability is high, males are predicted to partition their reproductive effort among multiple partners to avoid resource depletion before mating opportunities have ceased. We tested this prediction in males of the spider Pisaura mirabilis,...

Population structure and genetic diversity of sheep breeds in the Kyrgyzstan

Tatiana Deniskova, Arsen Dotsev, Eugenia Lushihina, Alexey Shakhin, Elisabeth Kunz, Henry Reyer, Klaus Wimmers, Negar Khayatzadeh, Johann Sölkner, Alexander Sermyagin, Asankadyr Zhunushev, Gottfried Brem & Natalia Zinovieva
Sheep are a main livestock species of Kyrgyzstan, a Central Asian country with predominating mountain terrain. The current gene pool of local sheep resources has been forming under diverse climate conditions from the era of the trading caravans of the Great Silk Road, through the Soviet period of large-scale livestock improvements, which was followed by the deep crisis at the end of the 20th century, up to now. However, not much is known about the...

Data from: Dietary carotenoids affect the development of individual differences and behavioral plasticity

Shannon R. Kelleher, Aimee J. Silla, Petri T. Niemelä, Niels J. Dingemanse & Phillip G. Byrne
Nutritional conditions experienced during development are expected to play a key role in shaping an individual’s behavioral phenotype. The long term, irreversible effects of nutritional conditions on behavioral variation among and within individuals remains largely unexplored. This study aimed to investigate how long-term carotenoid availability (representing low vs. high quality nutritional conditions) during both larval and adult life stages influences the expression of among-individual variation (animal personality) and within-individual variation (behavioral plasticity). We tested for...

Data from: Genotype-free estimation of allele frequencies reduces bias and improves demographic inference from RADSeq data

Vera Warmuth, Hans Ellegren & Vera M. Warmuth
Restriction-site associated sequencing (RADSeq) facilitates rapid generation of thousands of genetic markers at relatively low cost; however, several sources of error specific to RADSeq methods often lead to biased estimates of allele frequencies and thereby to erroneous population genetic inference. Estimating the distribution of sample allele frequencies without calling genotypes was shown to improve population inference from whole genome sequencing data, but the ability of this approach to account for RADSeq-specific biases remains unexplored. Here...

Data from: Individual differences in behaviour explain variation in survival: a meta-analysis

Maria Moiron, Kate Laskowski & Petri Niemelä
Research focusing on among-individual differences in behaviour (“animal personality”) has been blooming for over a decade. One of the central theories explaining the maintenance of such behavioural variation posits that individuals expressing greater “risky” behaviours should suffer higher mortality. Here, for the first time, we synthesize the existing empirical evidence for this key prediction. Our results did not support this prediction as there was no directional relationship between riskier behaviour and greater mortality; however there...

Data from: Stochastic character mapping of state-dependent diversification reveals the tempo of evolutionary decline in self-compatible Onagraceae lineages

William A Freyman & Sebastian Höhna
A major goal of evolutionary biology is to identify key evolutionary transitions that correspond with shifts in speciation and extinction rates. Stochastic character mapping has become the primary method used to infer the timing, nature, and number of character state transitions along the branches of a phylogeny. The method is widely employed for standard substitution models of character evolution. However, current approaches cannot be used for models that specifically test the association of character state...

Data from: Non-consumptive effects of predation: does perceived risk strengthen the genetic integration of behaviour and morphology in stickleback?

Niels Dingemanse, Iain Barber & Ned Dochtermann
Predators can shape genetic correlations in prey by altering prey perception of risk. We manipulated perceived risk to test whether such non-consumptive effects tightened behavioural trait correlations in wild-caught stickleback from high- compared to low-risk environments due to genetic variation in plasticity. We expected tighter genetic correlations within perceived risk treatments than across them, and tighter genetic correlations in high-risk than in low-risk treatments. We identified genetic variation in plasticity, with genetic correlations between boldness,...

Genetic overlap and causal inferences between kidney function and cerebrovascular disease

Sandro Marini, Marios Georgakis, Jaeyoon Chung, Jonathan Henry, Martin Dichgans, Jonathan Rosand, Christopher Anderson & Rainer Malik
Objective: Leveraging large-scale genetic data, we aimed to identify shared pathogenic mechanisms and causal relationships between impaired kidney function and cerebrovascular disease phenotypes. Methods: We used summary statistics from genome-wide association studies (GWAS) of kidney function traits (chronic kidney disease (CKD) diagnosis, estimated glomerular filtration rate (eGFR), and Urinary Albumin-to-Creatinine Ratio (UACR)), and of cerebrovascular disease phenotypes: ischemic stroke and its subtypes, intracerebral hemorrhage (ICH), white matter hyperintensities (WMH) on brain MRI. We (i) tested...

Data from: Genome of an iconic Australian bird: High-quality assembly and linkage map of the superb fairy-wren (Malurus cyaneus)

Joshua V. Peñalba, Yuan Deng, Qi Fang, Leo Joseph, Craig Moritz & Andrew Cockburn
The superb fairy-wren, Malurus cyaneus, is one of the most iconic Australian passerine species. This species belongs to an endemic Australasian clade, Meliphagides, which diversified early in the evolution of the oscine passerines. Today, the oscine passer- ines comprise almost half of all avian species diversity. Despite the rapid increase of available bird genome assemblies, this part of the avian tree has not yet been repre- sented by a high-quality reference. To rectify that, we...

Data from: A peculiar tooth renewal in a Jurassic ray-finned fish (Lepisosteiformes: †Scheenstia sp.)

Léa Leuzinger, Lionel Cavin, Adriana López-Arbarello & Jean-Paul Billon-Bruyat
Tooth replacement in vertebrates is extremely diverse, and its study in extinct taxa gives insights into the evolution of the different dental renewal modes. Based on µ-CT scans of a left lower jaw of the extinct fish †Scheenstia (Actinopterygii – Lepisosteiformes), we describe in detail a peculiar tooth replacement mode that is, as far as we could trace back in the literature, unique among vertebrates. The formation of the replacement teeth comprises a 180° rotation...
