Data from: Experimental manipulation of food availability leads to short-term intra-clutch adjustment in egg mass but not in yolk androgen or thyroid hormones

Suvi Ruuskanen, Veerle M. Darras, Bonnie De Vries, Marcel E. Visser & Ton G. G. Groothuis
In birds, mothers can affect their offspring's phenotype and thereby survival via egg composition. It is not well known to what extent and time-scales environmental variation in resource availability, either via resource constrains or adaptive adjustment to predicted rearing conditions, influences maternal effects. We experimentally studied whether egg and yolk mass and yolk hormone levels respond to short-term changes in food availability during laying in wild great tits Parus major. Our treatment groups were: 1)...

Data from: Locomotion during digestion changes current estimates of seed dispersal kernels by fish

Casper H. A. Van Leeuwen, Rosanne Beukeboom, Bart A. Nolet, Elisabeth S. Bakker, Bart J. A. Pollux & Bart J.A. Pollux
Dispersal of seeds by animals is an important mechanism regulating plant diversity, range expansions and invasions. Many birds, mammals, fish, and reptiles regularly ingest, transport and excrete viable seeds (known as endozoochory). The effectiveness of endozoochory is modelled in dispersal kernels: functions that describe seed shadows in the landscape by combining movement of animals with experimentally obtained seed retention times and survival. Currently, dispersal kernels use experimental data from resting animals, yet only moving animals...

Data from: Direct and indirect genetic effects in life history traits of flour beetles (Tribolium castaneum)

Esther D. Ellen, Katrijn Peeters, Merel Verhoeven, Rieta Gols, Jeffrey A. Harvey, Michael J. Wade, Marcel Dicke & Piter Bijma
Indirect genetic effects (IGEs) are the basis of social interactions among conspecifics, and can affect genetic variation of non-social as well as social traits. We used flour beetles (Tribolium castaneum) of two phenotypically distinguishable populations to estimate genetic (co)variances and the effect of IGEs on three life-history traits: development time (DT), growth rate (GR), and pupal body mass (BM). We found that GR was strongly affected by social environment with IGEs accounting for 18% of...

Data from: Low but contrasting neutral genetic differentiation shaped by winter temperature in European great tits

Mélissa Lemoine, Kay Lucek, Charles Perrier, Verena Saladin, Frank Adriaensen, Emilio Barba, Eduardo J. Belda, Anne Charmantier, Mariusz Cichon, Eeva Tapio, Arnaud Gregoire, Camilla A. Hinde, Arild Johnsen, Jan Komdeur, Raivo Mand, Erik Matthysen, Ana Claudia Norte, Natalia Pitala, Ben C. Sheldon, Tore Slagsvold, Joost M. Tinbergen, Janos Torok, Richard Ubels, Kees Van Oers, Marcel E. Visser … & Tapio Eeva
Gene flow is usually thought to reduce genetic divergence and impede local adaptation by homogenising gene pools between populations. However, evidence for local adaptation and phenotypic differentiation in highly mobile species, experiencing high levels of gene flow, is emerging. Assessing population genetic structure at different spatial scales is thus a crucial step towards understanding mechanisms underlying intraspecific differentiation and diversification. Here, we studied the population genetic structure of a highly mobile species – the great...

Data from: Effects of spatial plant-soil feedback heterogeneity on plant performance in monocultures

E. R. Jasper Wubs & T. Martijn Bezemer
1. Plant-soil feedback (PSF) effects have almost exclusively been quantified on homogeneous soils, but as different plant species will influence their local soil differently in reality PSF effects will be spatially heterogeneous. Whether plant performance in soils with spatially heterogeneous PSF can be predicted from pot experiments with homogeneous soils is unclear. 2. In a greenhouse experiment we tested the response of monocultures of six grassland species (two grasses, two legumes, and two forbs) to...

Data from: The epigenetic footprint of poleward range-expanding plants in apomictic dandelions

Veronica Preite, L. Basten Snoek, Carla Oplaat, Arjen Biere, Wim H. Van Der Putten & Koen J. F. Verhoeven
Epigenetic modifications, such as DNA methylation variation, can generate heritable phenotypic variation independent of the underlying genetic code. However, epigenetic variation in natural plant populations is poorly documented and little understood. Here, we test whether northward range expansion of obligate apomicts of the common dandelion (Taraxacum officinale) is associated with DNA methylation variation. We characterized and compared patterns of genetic and DNA methylation variation in greenhouse-reared offspring of T. officinale that were collected along a...

Data from: Effects of spring temperatures on the strength of selection on timing of reproduction in a long-distance migratory bird

Marcel E. Visser, Phillip Gienapp, Arild Husby, Michael Morrisey, Iván De La Hera, Francisco Pulido & Christiaan Both
Climate change has differentially affected the timing of seasonal events for interacting trophic levels, and this has often led to increased selection on seasonal timing. Yet, the environmental variables driving this selection have rarely been identified, limiting our ability to predict future ecological impacts of climate change. Using a dataset spanning 31 years from a natural population of pied flycatchers (Ficedula hypoleuca), we show that directional selection on timing of reproduction intensified in the first...

Data from: Stressful colors: corticosterone concentrations in a free-living songbird vary with the spectral composition of experimental illumination

Jenny Q. Ouyang, Maaike De Jong, Michaela Hau, Marcel E. Visser, Roy H. A. Van Grunsven & Kamiel Spoelstra
Organisms have evolved under natural daily light/dark cycles for millions of years. These cycles have been disturbed as night-time darkness is increasingly replaced by artificial illumination. Investigating the physiological consequences of free-living organisms in artificially lit environments is crucial to determine whether nocturnal lighting disrupts circadian rhythms, changes behaviour, reduces fitness and ultimately affects population numbers. We make use of a unique, large-scale network of replicated field sites which were experimentally illuminated at night using...

Data from: Soil microbiome responses to the short-term effects of Amazonian deforestation

Acácio A. Navarrete, Siu M. Tsai, Lucas W. Mendes, Karoline Faust, Mattias De Hollander, Noriko A. Cassman, Johannes A. Van Veen, Eiko E. Kuramae & Jeroen Raes
Slash-and-burn clearing of forest typically results in increase in soil nutrient availability. However, the impact of these nutrients on the soil microbiome is not known. Using next generation sequencing of 16S rRNA gene and shotgun metagenomic DNA, we compared the structure and the potential functions of bacterial community in forest soils to deforested soils in the Amazon region and related the differences to soil chemical factors. Deforestation decreased soil organic matter content and factors linked...

Data from: Peatland vascular plant functional types affect methane dynamics by altering microbial community structure

Bjorn J. M. Robroek, Vincent E. J. Jassey, Martine A. R. Kox, Roeland L. Berendsen, Robert T. E. Mills, Lauric Cécillon, Jéremy Puissant, Marion Meima–Franke, Peter A. H. M. Bakker, Paul L. E. Bodelier & Marion Meima-Franke
1. Peatlands are natural sources of atmospheric methane (CH4), an important greenhouse gas. It is established that peatland methane dynamics are controlled by both biotic and abiotic conditions, yet the interactive effect of these drivers is less studied and consequently poorly understood. 2. Climate change affects the distribution of vascular plant functional types (PFTs) in peatlands. By removing specific PFTs, we assessed their effects on peat organic matter chemistry, microbial community composition and on potential...

Data from: Assembly mechanisms determining high species turnover in aquatic communities over regional and continental scales

Duarte S. Viana, Jordi Figuerola, Klaus Schwenk, Marina Manca, Anders Hobæk, Marit Mjelde, Christopher D. Preston, Richard J. Gornall, Jane M. Croft, Robert A. King, Andy J. Green & Luis Santamaría
Niche and neutral processes drive community assembly and metacommunity dynamics, but their relative importance might vary with the spatial scale. The contribution of niche processes is generally expected to increase with increasing spatial extent at a higher rate than that of neutral processes. However, the extent to what community composition is limited by dispersal (usually considered a neutral process) over increasing spatial scales might depend on the dispersal capacity of composing species. To investigate the...

Data from: The impact of conservation management on the community composition of multiple organism groups in eutrophic interconnected man-made ponds

Pieter Lemmens, Joachim Mergeay, Jeroen Van Wichelen, Luc De Meester & Steven A. J. Declerck
Ponds throughout the world are subjected to a variety of management measures for purposes of biodiversity conservation. Current conservation efforts typically comprise a combination of multiple measures that directly and indirectly impact a wide range of organism groups. Knowledge of the relative impact of individual measures on different taxonomic groups is important for the development of effective conservation programs. We conducted a field study of 28 man-made ponds, representing four management types differing in the...

Data from: Natural epigenetic variation contributes to heritable flowering divergence in a widespread asexual dandelion lineage

Rutger A. Wilschut, Carla Oplaat, L. Basten Snoek, Jan Kirschner & Koen J. F. Verhoeven
Epigenetic variation has been proposed to contribute to the success of asexual plants, either as a contributor to phenotypic plasticity or by enabling transient adaptation via selection on transgenerationally stable, but reversible, epialleles. While recent studies in experimental plant populations have shown the potential for epigenetic mechanisms to contribute to adaptive phenotypes, it remains unknown whether heritable variation in ecologically relevant traits is at least partially epigenetically determined in natural populations. Here, we tested the...

Data from:Differential induction of plant chemical defenses by parasitized and unparasitized herbivores: consequences for reciprocal, multitrophic interactions

Paul J. Ode, Jeffrey A. Harvey, Michael Riechelt, Jonathan Gershenzon & Rieta Gols
Insect parasitoids can play ecologically important roles in virtually all terrestrial plant–insect herbivore interactions, yet whether parasitoids alter the defensive traits that underlie interactions between plants and their herbivores remains a largely unexplored question. Here, we examined the reciprocal trophic interactions among populations of the wild cabbage Brassica oleracea that vary greatly in their production of defensive secondary compounds – glucosinolates (GSs), a generalist herbivore, Trichoplusia ni, and its polyembryonic parasitoid Copidosoma floridanum. In a...

Data from: Tackling extremes: challenges for ecological and evolutionary research on extreme climatic events

Liam D. Bailey & Martijn Van De Pol
1. Extreme climatic events (ECEs) are predicted to become more frequent as the climate changes. A rapidly increasing number of studies - though few on animals - suggest that the biological consequences of ECEs can be severe. 2. However, ecological research on the impacts of extreme climatic events (ECEs) has been limited by a lack of cohesiveness and structure. ECEs are often poorly defined and have often been confusingly equated with climatic variability, making comparison...

Data from: Fitness consequences of indirect plant defence in the annual weed, Sinapis arvensis

Rieta Gols, Roel Wagenaar, Erik H. Poelman, Marjolein Kruidhof, Joop J. A. Van Loon, Jeffrey A. Harvey, H. Marjolein Kruidhof & Joop J.A. Van Loon
1. Plant traits that enhance the attraction of the natural enemies of their herbivores have been postulated to function as an ‘indirect defence’. An important underlying assumption is that this enhanced attraction results in increased plant fitness due to reduced herbivory. This assumption has been rarely tested. 2. We investigated whether there are fitness consequences for the charlock mustard Sinapis arvensis, a short-lived outcrossing annual weedy plant, when exposed to groups of large cabbage white...

Data from: Estimating the variation, autocorrelation, and environmental sensitivity of phenotypic selection

Luis-Miguel Chevin, Marcel E. Visser & Jarle Tufto
Despite considerable interest in temporal and spatial variation of phenotypic selection, very few methods allow quantifying this variation while correctly accounting for the error variance of each individual estimate. Furthermore, the available methods do not estimate the autocorrelation of phenotypic selection, which is a major determinant of eco-evolutionary dynamics in changing environments. We introduce a new method for measuring variable phenotypic selection using random regression. We rely on model selection to assess the support for...

Data from: Replicated analysis of the genetic architecture of quantitative traits in two wild great tit populations

Anna W. Santure, Jocelyn Poissant, Isabelle De Cauwer, Kees Van Oers, Matthew R. Robinson, John L. Quinn, Martien A. M. Groenen, Marcel E. Visser, Ben C. Sheldon & Jon Slate
Currently there is much debate on the genetic architecture of quantitative traits in wild populations. Is trait variation influenced by many genes of small effect or by a few genes of major effect? Where is additive genetic variation located in the genome? Do the same loci cause similar phenotypic variation in different populations? Great tits (Parus major) have been studied extensively in long-term studies across Europe, and consequently are considered an ecological 'model organism'. Recently,...

Data from: Complementarity and selection effects in early and mid-successional plant communities are differentially affected by plant-soil feedback

Jingying Jing, T. Martijn Bezemer & Wim H. Van Der Putten
1. Many studies that provided evidence for a positive relationship between plant diversity and productivity have proposed that this effect may be explained by complementarity among species in resources utilization, or selection of particularly productive species in high-diversity plant communities. Recent studies have related the higher productivity in diverse plant communities to suppression of pathogenic soil biota. If soil biota plays a role in diversity–productivity relationships, the question remains about how they may influence complementarity...

Data from: Parasitism overrides herbivore identity allowing hyperparasitoids to locate their parasitoid host by using herbivore-induced plant volatiles

Feng Zhu, Colette Broekgaarden, Berhane T. Weldegergis, Jeffrey A. Harvey, Ben Vosman, Marcel Dicke & Erik H. Poelman
Foraging success of predators profoundly depends on reliable and detectable cues indicating the presence of their often inconspicuous prey. Carnivorous insects rely on chemical cues to optimize foraging efficiency. Hyperparasitoids that lay their eggs in the larvae or pupae of parasitic wasps may find their parasitoid hosts developing in different herbivores. They can use herbivore-induced plant volatiles (HIPVs) to locate parasitized caterpillars. Because different herbivore species induce different HIPV emission from plants, hyperparasitoids may have...

Data from: Species-specific plant-soil feedback effects on above-ground plant-insect interactions

Martine Kos, Maarten A. B. Tuijl, Joris De Roo, Patrick P. J. Mulder & T. Martijn Bezemer
1. Plant–soil feedback (PSF) effects on plant performance strongly depend on the plant species that conditioned the soil. Recent studies have shown that PSF can change above-ground plant–insect interactions via soil-mediated changes in plant quality, but whether these effects depend on species-specific soil conditioning is unknown. We examined how PSF effects of several plant species influence above-ground plant–aphid interactions. 2. We grew ragwort (Jacobaea vulgaris) in field soil conditioned specifically by 10 plant species, belonging...

Data from: Costs of sleeping in: circadian rhythms influence cuckoldry risk in a songbird

Timothy Greives, Sjouke Kingma, Bart Kranstauber, Kim Mortega, Martin Wikelski, Kees Van Oers, Christa Mateman, Glen Ferguson, Giulia Beltrami, Michaela Hau, Sjouke A. Kingma & Timothy J. Greives
1. Circadian (i.e. daily) regulation of behaviors is thought to provide fitness benefits to organisms by enabling them to anticipate diel changes in the environment, such as sunrise. 2. A common behavior among socially monogamous songbirds that usually takes place in the early mornings is extra-pair mating, i.e. copulating with partners outside of the social pair bond. 3. Thus, variation in when individuals begin their daily activity may influence their reproductive success; early risers may...

Data from: Native and non-native plants provide similar refuge to invertebrate prey, but less than artificial plants

Bart M.C. Grutters, Bart J.A. Pollux, Wilco C.E.P. Verberk, Elisabeth S. Bakker, Bart M. C. Grutters, Bart J. A. Pollux & Wilco C. E. P. Verberk
Non-native species introductions are widespread and can affect ecosystem functioning by altering the structure of food webs. Invading plants often modify habitat structure, which may affect the suitability of vegetation as refuge and could thus impact predator-prey dynamics. Yet little is known about how the replacement of native by non-native vegetation affects predator-prey dynamics. We hypothesize that plant refuge provisioning depends on (1) the plant’s native status, (2) plant structural complexity and morphology, (3) predator...

Data from: Evidence from pyrosequencing indicates that natural variation in animal personality is associated with DRD4 DNA methylation

Eveline C. Verhulst, A. Christa Mateman, Mathijs V. Zwier, Samuel P. Caro, Koen J. F. Verhoeven, Kees Van Oers & Koen J.F. Verhoeven
Personality traits are heritable and respond to natural selection, but are at the same time influenced by the ontogenetic environment. Epigenetic effects, such as DNA methylation, have been proposed as a key mechanism to control personality variation. However, to date little is known about the contribution of epigenetic effects to natural variation in behaviour. Here, we show that great tit (Parus major) lines artificially selected for divergent exploratory behaviour for four generations differ in their...

Data from: Environmental factors and traits that drive plant litter decomposition do not determine home-field advantage effects

Ciska G. F. Veen, Maja K. Sundqvist, David A. Wardle & G. F. Ciska Veen
The ‘home-field advantage’ (HFA) hypothesis predicts that plant litter is decomposed faster than expected underneath the plant from which it originates (‘home’) than underneath other plants (‘away’), because decomposer communities are specialized to break down litter from the plants they associate with. However, empirical evidence shows that the occurrence of HFA is highly variable, and the reasons for this are little understood. In our study we progress our understanding by investigating whether HFA is stronger...
