Popular procedures to control the chance of making type I errors when multiple statistical tests are performed come at a high cost: reduction in power. As number increases, power for an individual test may become unacceptably low. This is consequence minimizing even single error, which aim of, instance, Bonferroni and sequential procedures. An alternative approach, false discovery rate (FDR), has recently been advocated ecological studies. approach aims controlling proportion significant...
*DNA methylation can cause heritable phenotypic modifications in the absence of changes DNA sequence. Environmental stresses trigger and this may have evolutionary consequences, even sequence variation. However, it remains largely unknown to what extent environmentally induced are transmitted offspring, whether observed variation is truly independent or a downstream consequence genetic between individuals. *Genetically identical apomictic dandelion (Taraxacum officinale) plants were exposed...
Summary 1. Feedback between plants and soil organisms has become widely recognized as a driving force of community composition ecosystem functioning. However, there is little uniformity in quantification analysis plant–soil feedback effects. Meta‐analysis suggested that the various experimental methods tend to result different values. Yet, direct comparison approaches their statistical analyses lacking. 2. We used currently applied calculate value ranges compared those based on actual...
Abstract For over 50 years, the great tit ( Parus major ) has been a model species for research in evolutionary, ecological and behavioural research; particular, learning cognition have intensively studied. Here, to provide further insight into molecular mechanisms behind these important traits, we de novo assemble reference genome whole-genome re-sequence another 29 individuals from across Europe. We show an overrepresentation of genes related neuronal functions, regions under positive...
Abstract Introduced exotic species encounter a wide range of non‐coevolved enemies and competitors in their new range. Evolutionary novelty is key aspect these interactions, but who benefits from novelty: the or antagonists? Paradoxically, argument has been used to explain both release suppression by natural enemies. We argue that this paradox can be solved considering underlying interaction mechanisms. Using plant defenses as model, we mismatches between enemy traits enhance invasiveness...
Abstract While traits and trait plasticity are partly genetically based, investigating epigenetic mechanisms may provide more nuanced understanding of the underlying response to environment. Using AFLP methylation‐sensitive , we tested hypothesis that differentiation habitats along natural salt marsh environmental gradients occurs at epigenetic, but not genetic loci in two perennials. We detected significant structure among populations subpopulations, found multilocus patterns habitat type...
Heritable epigenetic modulation of gene expression is a candidate mechanism to explain parental environmental effects on offspring phenotypes, but current evidence for environment-induced changes that persist in generations scarce. In apomictic dandelions, exposure various stresses was previously shown heritably alter DNA methylation patterns. this study we explore whether these induced are accompanied by heritable phenotypes. We observed jasmonic acid treatment specific leaf area and...
Abstract Environmentally induced phenotypic plasticity may be a critical component of response to changing environments. We examined local differentiation and adaptive in elevated temperature half‐sib lines collected across an elevation gradient for the alpine herb, Wahlenbergia ceracea . Using Amplified Fragment Length Polymorphism (AFLP), we found low but significant genetic between low‐ high‐elevation seedlings, seedlings originating from elevations grew faster showed stronger responses...
Transgenerational effects (TGE) can modify phenotypes of offspring generations playing thus a potentially important role in ecology and evolution many plant species. These have been studied mostly across sexually reproducing A substantial proportion species are however asexually, for instance via clonal growth. TGE thought to be enabled by heritable epigenetic modification DNA, although unambiguous evidence is still scarce. On the herb white clover (Trifolium repens), we tested generality...
Plants produce large amounts of secondary metabolites in their shoots and roots store them specialized secretory structures. Although structures are commonly assumed to have a defensive function, evidence that they benefit plant fitness under herbivore attack is scarce, especially below ground. Here, we tested whether latex produced by the common dandelion (Taraxacum officinale agg.) decrease performance its major native insect root herbivore, larvae cockchafer (Melolontha melolontha),...
DNA methylation is an epigenetic mechanism that has the potential to affect plant phenotypes and responsive environmental genomic stresses such as hybridization polyploidization. We explored de novo variation arises during formation of triploid asexual dandelions from diploid sexual mother plants using methylation-sensitive amplified fragment length polymorphism (MS-AFLP) analysis. In dandelions, apomictic asexuals are produced mothers fertilized by polyploid pollen donors. asked whether...
Abstract Epigenetic variation has been proposed to contribute the success of asexual plants, either as a contributor phenotypic plasticity or by enabling transient adaptation via selection on transgenerationally stable, but reversible, epialleles. While recent studies in experimental plant populations have shown potential for epigenetic mechanisms adaptive phenotypes, it remains unknown whether heritable ecologically relevant traits is at least partially epigenetically determined natural...
Plant phenotypes can be affected by environments experienced their parents. Parental environmental effects are reported for the first offspring generation and some studies showed persisting in second further generations. However, expression of these transgenerational proved context-dependent reproducibility low. Here we study context-dependency evaluating parental under a range induction evaluation conditions. We systematically evaluated two factors that influence effects: single- versus...
Plants respond to herbivore attack by rapidly inducing defenses that are mainly regulated jasmonic acid (JA). Due the systemic nature of induced defenses, root herbivores can also result in a shoot response and vice versa, causing interactions between above- belowground herbivores. However, little is known about molecular mechanisms underlying these interactions. We investigated whether plants differently when roots or shoots induced. mimicked applying JA Brassica oleracea analyzed chemical...
Personality traits are heritable and respond to natural selection, but at the same time influenced by ontogenetic environment. Epigenetic effects, such as DNA methylation, have been proposed a key mechanism control personality variation. However, date little is known about contribution of epigenetic effects variation in behaviour. Here, we show that great tit (Parus major) lines artificially selected for divergent exploratory behaviour four generations differ their methylation levels...
Studies on vertebrate DNA methylomes have revealed a regulatory role of tissue specific methylation in relation to gene expression. However, it is not well known how tissue-specific varies between different functional and structural components genes genomes. Using whole-genome bisulfite sequencing data we here describe both CpG non-CpG profiles whole blood brain features, CpG-islands (CGIs), transposable elements (TE), their roles an ecological model species, the great tit (Parus major). We...
