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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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: Sex differences and allee effects shape the dynamics of sex-structured invasions

Allison K. Shaw, Hanna Kokko & Michael G. Neubert
The rate at which a population grows and spreads can depend on individual behaviour and interactions with others. In many species with two sexes, males and females differ in key life history traits (e.g. growth, survival, dispersal), which can scale up to affect population rates of growth and spread. In sexually reproducing species, the mechanics of locating mates and reproducing successfully introduce further complications for predicting the invasion speed (spread rate), as both can change...

Data from: The genetic architecture of freezing tolerance varies across the range of Arabidopsis thaliana

Matthew W. Horton, Glenda Willems, Eriko Sasaki, Maarten Koornneef & Magnus Nordborg
The capacity to tolerate freezing temperatures limits the geographical distribution of many plants, including several species of agricultural importance. However, the genes involved in freezing tolerance remain largely unknown. Here, we describe the variation in constitutive freezing tolerance that occurs among worldwide accessions of Arabidopsis thaliana. We found that although plants from high latitudes tend to be more freezing tolerant than plants from low latitudes, the environmental factors that shape cold adaptation differ across the...

Data from: The copulatory plug delays ejaculation by rival males and affects sperm competition outcome in house mice

Andreas Sutter & Anna K. Lindholm
Females of many species mate with multiple males (polyandry), resulting in male–male competition extending to post-copulation (sperm competition). Males adapt to such post-copulatory sexual selection by altering features of their ejaculate that increase its competitiveness and/or by decreasing the risk of sperm competition through female manipulation or interference with rival male behaviour. At ejaculation, males of many species deposit copulatory plugs, which are commonly interpreted as a male adaptation to post-copulatory competition and are thought...

Data from: Spatially cascading effect of perturbations in experimental meta-ecosystems

Eric Harvey, Isabelle Gounand, Pravin Ganesanandamoorthy & Florian Altermatt
Ecosystems are linked to neighbouring ecosystems not only by dispersal, but also by the movement of subsidy. Such subsidy couplings between ecosystems have important landscape-scale implications because perturbations in one ecosystem may affect community structure and functioning in neighbouring ecosystems via increased/decreased subsidies. Here, we combine a general theoretical approach based on harvesting theory and a two-patch protist meta-ecosystem experiment to test the effect of regional perturbations on local community dynamics. We first characterized the...

Data from: Differential neural processing during motor imagery of daily activities in chronic low back pain patients

Andrea Vrana, Sabina Hotz-Boendermaker, Philipp Stämpfli, Jürgen Hänggi, Erich Seifritz, B. Kim Humphreys & Michael L. Meier
Chronic low back pain (chronic LBP) is both debilitating for patients but also a major burden on the health care system. Previous studies reported various maladaptive structural and functional changes among chronic LBP patients on spine- and supraspinal levels including behavioral alterations. However, evidence for cortical reorganization in the sensorimotor system of chronic LBP patients is scarce. Motor Imagery (MI) is suitable for investigating the cortical sensorimotor network as it serves as a proxy for...

Data from: Above and belowground responses of four tundra plant functional types to deep soil heating and surface soil fertilization

Peng Wang, Juul Limpens, Liesje Mommer, Jasper Van Ruijven, Ake L. Nauta, Frank Berendse, Gabriela Schaepman-Strub, Daan Blok, Trofim C. Maximov, Monique M. P. D. Heijmans & Monique M.P.D. Heijmans
1.Climate warming is faster in the Arctic than the global average. Nutrient availability in the tundra soil is expected to increase by climate warming through 1) accelerated nutrient mobilization in the surface soil layers, and 2) increased thawing depths during the growing season which increases accessibility of nutrients in the deeper soil layers. Both processes may initiate shifts in tundra vegetation composition. It is important to understand the effects of these two processes on tundra...

Data from: Validation of a fecal glucocorticoid assay to assess adrenocortical activity in meerkats using physiological and biological stimuli

Ines Braga Goncalves, Michael Heistermann, Peter Santema, Ben Dantzer, Jelena Mausbach, Andre Ganswindt & Marta B. Manser
In mammals, glucocorticoid (i.e. GC) levels have been associated with specific life-history stages and transitions, reproductive strategies, and a plethora of behaviors. Assessment of adrenocortical activity via measurement of glucocorticoid metabolites in feces (FGCM) has greatly facilitated data collection from wild animals, due to its non-invasive nature, and thus has become an established tool in behavioral ecology and conservation biology. The aim of our study was to validate a fecal glucocorticoid assay for assessing adrenocortical...

Data from: The value of biodiversity for the functioning of tropical forests: insurance effects during the first decade of the Sabah biodiversity experiment

Sean L. Tuck, Michael J. O'Brien, Christopher D. Philipson, Philippe Saner, Matteo Tanadini, Dzaeman Dzulkifli, H. Charles J. Godfray, Elia Godoong, Reuben Nilus, Robert C. Ong, Bernhard Schmid, Waidi Sinun, Jake L. Snaddon, Martijn Snoep, Hamzah Tangki, John Tay, Philip Ulok, Yap Sau Wai, Maja Weilenmann, Glen Reynolds & Andy Hector
One of the main environmental threats in the tropics is selective logging, which has degraded large areas of forest. In southeast Asia, enrichment planting with seedlings of the dominant group of dipterocarp tree species aims to accelerate restoration of forest structure and functioning. The role of tree diversity in forest restoration is still unclear, but the ‘insurance hypothesis’ predicts that in temporally and spatially varying environments planting mixtures may stabilize functioning owing to differences in...

Data from: Assessing current genetic status of the Hainan gibbon using historical and demographic baselines: implications for conservation management of species of extreme rarity

Jessica V. Bryant, Dada Gottelli, Xinyuan Zeng, Xiaojiang Hong, Bosco P.L. Chan, John R. Fellowes, Ya-Ping Zhang, Jing Luo, Christopher Durrant, Thomas Geissmann, Helen J. Chatterjee & Samuel T. Turvey
Evidence-based conservation planning is crucial for informing management decisions for species of extreme rarity, but collection of robust data on genetic status or other parameters can be extremely challenging for such species. The Hainan gibbon, possibly the world's rarest mammal, consists of a single population of ~25 individuals restricted to one protected area on Hainan Island, China, and has persisted for over 30 years at exceptionally low population size. Analysis of genotypes at 11 microsatellite...
