Data from: Reduced flight-to-light behaviour of moth populations exposed to long-term urban light pollution

Florian Altermatt & Dieter Ebert
The globally increasing light pollution is a well-recognized threat to ecosystems, with negative effects on human, animal and plant wellbeing. The most well-known and widely documented consequence of light pollution is the generally fatal attraction of nocturnal insects to artificial light sources. However, the evolutionary consequences are unknown. Here we report that moth populations from urban areas with high, globally relevant levels of light pollution over several decades show a significantly reduced flight-to-light behaviour compared...

Data from: Matrilineal inheritance of a key mediator of prenatal maternal effects

Barbara Tschirren, Ann-Kathrin Ziegler, Joel L. Pick, Monika Okuliarová, Michal Zeman & Mathieu Giraudeau
Sex-linkage is predicted to evolve in response to sex-specific or sexually antagonistic selection. In line with this prediction, most sex-linked genes are associated with reproduction in the respective sex. In addition to traits directly involved in fertility and fecundity, mediators of maternal effects may be predisposed to evolve sex-linkage, because they indirectly affect female fitness through their effect on offspring phenotype. Here, we test for sex-linked inheritance of a key mediator of prenatal maternal effects...

Data from: Manipulating virulence factor availability can have complex consequences for infections

Michael Weigert, Adin Ross-Gillespie, Anne Leinweber, Gabriella Pessi, Sam P. Brown & Rolf Kuemmerli
Given the rise of bacterial resistance against antibiotics, we urgently need alternative strategies to fight infections. Some propose we should disarm rather than kill bacteria, through targeted disruption of their virulence factors. It is assumed that this approach (i) induces weak selection for resistance because it should only minimally impact bacterial fitness, and (ii) is specific, only interfering with the virulence factor in question. Given that pathogenicity emerges from complex interactions between pathogens, hosts, and...

Data from: Infection-induced behavioural changes reduce connectivity and the potential for disease spread in wild mice contact networks

Patricia C. Lopes, Per Block & Barbara König
Infection may modify the behaviour of the host and of its conspecifics in a group, potentially altering social connectivity. Because many infectious diseases are transmitted through social contact, social connectivity changes can impact transmission dynamics. Previous approaches to understanding disease transmission dynamics in wild populations were limited in their ability to disentangle different factors that determine the outcome of disease outbreaks. Here we ask how social connectivity is affected by infection and how this relationship...

Data from: How do cold-adapted plants respond to climatic cycles? interglacial expansion explains current distribution and genomic diversity in Primula farinosa L.

Spyros Theodoridis, Christophe Randin, Peter Szövényi, Florian C. Boucher, Theofania S. Patsiou & Elena Conti
Understanding the effects of past climatic fluctuations on the distribution and population-size dynamics of cold-adapted species is essential for predicting their responses to ongoing global climate change. In spite of the heterogeneity of cold-adapted species, two main contrasting hypotheses have been proposed to explain their responses to Late Quaternary glacial cycles, namely, the interglacial contraction versus the interglacial expansion hypotheses. Here, we use the cold-adapted plant Primula farinosa to test two demographic models under each...

Data from: Mate guarding and frequent copulation in birds: a meta-analysis of their relationship to paternity and male phenotype

Anna M.F. Harts, Isobel Booksmythe, Michael D. Jennions & Anna M. F. Harts
In many birds males are presumed to protect their paternity by closely guarding their mate or copulating frequently with her. Both these costly behaviours are assumed to reduce the risk and/or intensity of sperm competition. However, despite many studies on avian extra-pair paternity, it remains unclear how strongly these behaviours are related to fitness and other key life-history traits. Here we conduct meta-analyses to address two questions. First, are mate guarding and/or frequent copulation positively...

Data from: Miocene flooding events of western Amazonia

Carlos Jaramillo, Ingrid Romero, Carlos D'Apolito, German Bayona, Edward Duarte, Stephen Louwye, Jaime Escobar, Javier Luque, Jorge D. Carrillo-Briceño, Vladimir Zapata, Andrés Mora, Stefan Schouten, Michael Zavada, Guy Harrington, John Ortiz & Frank P. Wesselingh
There is a considerable controversy about whether western Amazonia was ever covered by marine waters during the Miocene [23 to 5 Ma (million years ago)]. We investigated the possible occurrence of Miocene marine incursions in the Llanos and Amazonas/Solimões basins, using sedimentological and palynological data from two sediment cores taken in eastern Colombia and northwestern Brazil together with seismic information. We observed two distinct marine intervals in the Llanos Basin, an early Miocene that lasted...

Data from: Female monkeys use both the carrot and the stick to promote male participation in intergroup fights

T. Jean Marie Arseneau-Robar, Anouk Lisa Taucher, Eliane Müller, Carel Van Schaik, Redouan Bshary & Erik P. Willems
Group-level cooperation often poses a social dilemma in which joint action may be difficult to achieve. Theoretical models and experimental work on humans show that social incentives, such as punishment of defectors and rewarding of cooperators, can promote cooperation in groups of unrelated individuals. Here, we demonstrate that these processes can operate in a non-human animal species, and be used to effectively promote the production of a public good. We took advantage of the fact...

Data from: In search of genetic constraints limiting the evolution of egg size: Direct and correlated responses to artificial selection on a prenatal maternal effector

Joel Pick, Pascale Hutter & Barbara Tschirren
Maternal effects are an important force in nature, but the evolutionary dynamics of the traits that cause them are not well understood. Egg size is known to be a key mediator of prenatal maternal effects with an established genetic basis. Contrary to theoretical expectations for fitness-related traits, there is a large amount of additive genetic variation in egg size observed in natural populations. One possible mechanism for the maintenance of this variation is through genetic...

Data from: The strength of the association between heterozygosity and probability of interannual local recruitment increases with environmental harshness in blue tits

Esperanza S. Ferrer, Vicente García-Navas, Juan José Sanz & Joaquín Ortego
The extent of inbreeding depression and the magnitude of heterozygosity–fitness correlations (HFC) have been suggested to depend on the environmental context in which they are assayed, but little evidence is available for wild populations. We combine extensive molecular and capture–mark–recapture data from a blue tit (Cyanistes caeruleus) population to (1) analyze the relationship between heterozygosity and probability of interannual adult local recruitment and (2) test whether environmental stress imposed by physiologically suboptimal temperatures and rainfall...

Data from: Gauging the purported costs of public data archiving for long-term population studies

Simon Robin Evans
It was recently proposed that long-term population studies be exempted from the expectation that authors publicly archive the primary data underlying published articles. Such studies are valuable to many areas of ecological and evolutionary biological research, and multiple risks to their viability were anticipated as a result of public data archiving (PDA), ultimately all stemming from independent reuse of archived data. However, empirical assessment was missing, making it difficult to determine whether such fears are...

Data from: Amino acid change in an orchid desaturase enables mimicry of the pollinator’s sex pheromone

Khalid E. M. Sedeek, Edward Whittle, Daniela Guthörl, Ueli Grossniklaus, John Shanklin & Philipp Schlüter
Mimicry illustrates the power of selection to produce phenotypic convergence in biology [ 1 ]. A striking example is the imitation of female insects by plants that are pollinated by sexual deception of males of the same insect species [ 2–4 ]. This involves mimicry of visual, tactile, and chemical signals of females [ 2–7 ], especially their sex pheromones [ 8–11 ]. The Mediterranean orchid Ophrys exaltata employs chemical mimicry of cuticular hydrocarbons, particularly...

Data from: Information use shapes the dynamics of range expansions into environmental gradients

Emanuel A. Fronhofer, Nicolai Nitsche & Florian Altermatt
Globally, the geographical distributions of species are dynamic and strongly influenced by dispersal. At the same time, range dynamics feed back and may select for increased dispersal at expanding range fronts. This interplay between macroecological and evolutionary dynamics happens almost universally across environmental gradients and such gradients can have a direct impact on the fitness of organisms due to the match or mismatch between an individual's environmental optimum and the current conditions along the gradient....

Data from: Herbivore-induced DNA demethylation changes floral signalling and attractiveness to pollinators in Brassica rapa

Florian Schiestl, Philipp Schlüter, Roman Kellenberger, Roman T. Kellenberger, Philipp M. Schlüter & Florian P. Schiestl
Plants have to fine-tune their signals to optimise the trade-off between herbivore deterrence and pollinator attraction. An important mechanism in mediating plant-insect interactions is the regulation of gene expression via DNA methylation. However, the effect of herbivore-induced DNA methylation changes on pollinator-relevant plant signalling has not been systematically investigated. Here, we assessed the impact of foliar herbivory on DNA methylation and floral traits in the model crop plant Brassica rapa. Methylation-sensitive amplified fragment length polymorphism...

Data from: Paternal-specific S-allele transmission in sweet cherry (Prunus avium L.): the potential for sexual selection

Afif Hedhly, Ana Wünsch, Önder Kartal, María Herrero & José Ignacio Hormaza
Homomorphic self-incompatibility is a well-studied example of a physiological process that is thought to increase population diversity and reduce the expression of inbreeding depression. Whereas theoretical models predict the presence of a large number of S-haplotypes with equal frequencies at equilibrium, unequal allele frequencies have been repeatedly reported and attributed to sampling effects, population structure, demographic perturbation, sheltered deleterious mutations or selection pressure on linked genes. However, it is unclear to what extent unequal segregations...

Data from: Genome assembly and annotation of Arabidopsis halleri, a model for heavy metal hyperaccumulation and evolutionary ecology

Roman V. Briskine, Timothy Paape, Rie Shimizu-Inatsugi, Tomoaki Nishiyama, Satoru Akama, Jun Sese & Kentaro K. Shimizu
The self-incompatible species Arabidopsis halleri is a close relative of the self-compatible model plant Arabidopsis thaliana. The broad European and Asian distribution and heavy metal hyperaccumulation ability make A. halleri a useful model for ecological genomics studies. We used long-insert mate-pair libraries to improve the genome assembly of the A. halleri ssp. gemmifera Tada mine genotype (W302) collected from a site with high contamination by heavy metals in Japan. After five rounds of forced selfing,...

Data from: Interactive effects of exogenous and endogenous factors on demographic rates of an African rodent

Chloé R. Nater, Cindy I. Canale, Koen J. Van Benthem, Chi-Hang Yuen, Ivana Schoepf, Neville Pillay, Arpat Ozgul & Carsten Schradin
Exogenous and endogenous environmental factors can have simultaneous additive as well as interacting effects on life-history traits. Ignoring such interactions can lead to a biased understanding of variability in demographic rates and consequently population dynamics. These interactions have been the focus of decades-long debates on the mechanisms underlying small mammal population fluctuations. They have often been studied indirectly through seasonal effects, but studies considering them directly and more mechanistically are rare. We investigated the joint...

Data from: Rodent-avoidance, topography and forest structure shape territory selection of a forest bird

Gilberto Pasinelli, Alex Grendelmeier, Michael Gerber & Raphaël Arlettaz
Background - Understanding the factors underlying habitat selection is important in ecological and evolutionary contexts, and crucial for developing targeted conservation action in threatened species. However, the key factors associated to habitat selection often remain poorly known. We evaluated hypotheses related to abiotic and biotic factors thought to affect territory selection of the wood warbler Phylloscopus sibilatrix, a passerine living in an unpredictable environment owing to irregular rodent outbreaks and showing long-term declines particularly in...

Data from: Long-term effect of yolk carotenoid levels on testis size in a precocial bird

Mathieu Giraudeau, Ann-Kathrin Ziegler & Barbara Tschirren
Conditions experienced during prenatal development can have long-lasting organizational effects on offspring. Maternal carotenoids deposited in the eggs of birds and other oviparous species play an important role during fast embryonic growth and chick development through their antioxidant properties. However, the long-term consequences of variation in maternal carotenoid transfer for the offspring have seldom been considered. Since plasma carotenoid levels at adulthood are known to influence testis size and yolk carotenoid levels influence the ability...

Data from: Conserved but attenuated parental gene expression in allopolyploids: constitutive zinc hyperaccumulation in the allotetraploid Arabidopsis kamchatica

Timothy Paape, Masaomi Hatakeyama, Rie Shimizu-Inatsugi, Teo Cereghetti, Onda Yoshihiko, Tanaka Kenta, Jun Sese & Kentaro K. Shimizu
Allopolyploidization combines parental genomes and often confers broader species distribution. However, little is known about parentally transmitted gene expression underlying quantitative traits following allopolyploidization because of the complexity of polyploid genomes. The allopolyploid species Arabidopsis kamchatica is a natural hybrid of the zinc hyperaccumulator A. halleri and of the nonaccumulator A. lyrata. We found that A. kamchatica retained the ability to hyperaccumulate zinc from A. halleri and grows in soils with both low and high...

Data from: Genetic isolation between coastal and fishery-impacted, offshore bottlenose dolphin (Tursiops spp.) populations

Simon J. Allen, Kate A. Bryant, Robert H. S. Kraus, Neil R. Loneragan, Anna M. Kopps, Alexander M. Brown, Livia Gerber & Michael Krützen
The identification of species and population boundaries is important in both evolutionary and conservation biology. In recent years, new population genetic and computational methods for estimating population parameters and testing hypotheses in a quantitative manner have emerged. Using a Bayesian framework and a quantitative model-testing approach, we evaluated the species status and genetic connectedness of bottlenose dolphin (Tursiops spp.) populations off remote northwestern Australia, with a focus on pelagic 'offshore' dolphins subject to incidental capture...

Data from: Variation in parent-offspring kinship in socially monogamous systems with extra-pair reproduction and inbreeding

Jane M. Reid, Greta Bocedi, Pirmin Nietlisbach, Alexander Bradley Duthie, Matthew Ernest Wolak, Elizabeth A. Gow & Peter Arcese
Female extra-pair reproduction in socially monogamous systems is predicted to cause cuckolded socially-paired males to conditionally reduce paternal care, causing selection against extra-pair reproduction and underlying polyandry. However, existing models and empirical studies have not explicitly considered that cuckolded males might be related to their socially-paired female and/or to her extra-pair mate, and therefore be related to extra-pair offspring that they did not sire but could rear. Selection against paternal care, and hence against extra-pair...

Data from: Explaining high-diversity death assemblages: undersampling of the living community, out-of-habitat transport, time-averaging of rare taxa, and local extinction

Anja Buerkli & Anthony B. Wilson
Molluscan benthic assemblages provide unique opportunities for understanding both spatial and temporal patterns of biodiversity. Species richness in the shell remains found at a site (i.e. the death assemblage) is typically several times higher than in the counterpart living assemblage, reflecting a complex history of settlement, dissemination and decomposition post-mortem. We used high-density temporal and spatial sampling (>37’000 individuals representing 196 taxa) of a shallow (5-8 m) nearshore sandy habitat off the coast of south-east...

Data from: Size evolution in microorganisms masks trade-offs predicted by the growth rate hypothesis

Isabelle Gounand, Tanguy Daufresne, Dominique Gravel, Corinne Bouvier, Thierry Bouvier, Marine Combe, Claire Gougat-Barbera, Franck Poly, Clara Torres-Barceló & Nicolas Mouquet
Adaptation to local resource availability depends on responses in growth rate and nutrient acquisition. The growth rate hypothesis (GRH) suggests that growing fast should impair competitive abilities for phosphorus and nitrogen due to high demand for biosynthesis. However, in microorganisms, size influences both growth and uptake rates, which may mask trade-offs and instead generate a positive relationship between these traits (size hypothesis, SH). Here, we evolved a gradient of maximum growth rate (μmax) from a...

Data from: Trait-demography relationships underlying small mammal population fluctuations

Koen J. Van Benthem, Hannah Froy, Tim Coulson, Lowell L. Getz, Madan K. Oli & Arpat Ozgul
Large-scale fluctuations in abundance are a common feature of small mammal populations and have been the subject of extensive research. These demographic fluctuations are often associated with concurrent changes in the average body mass of individuals, sometimes referred to as the ‘Chitty effect’. Despite the long-standing recognition of this phenomenon, an empirical investigation of the underlying coupled dynamics of body mass and population growth has been lacking. Using long-term life-history data combined with a trait-based...
