Data from: Intraspecific trait variation and trade-offs within and across populations of a toxic dinoflagellate

Karen M. Brandenburg, Sylke Wohlrab, Uwe John, Anke Kremp, Jacqueline Jerney, Bernd Krock & Dedmer B. Van De Waal
Intraspecific trait diversity can promote the success of a species, as complementarity of functional traits within populations may enhance its competitive success and facilitates resilience to changing environmental conditions. Here, we experimentally determined the variation and relationships between traits in 15 strains of the toxic dinoflagellate Alexandrium ostenfeldii derived from two populations. Measured traits included growth rate, cell size, elemental composition, nitrogen uptake kinetics, toxin production and allelochemical potency. Our results demonstrate substantial variation in...

Data from: Effects of interspecific coexistence on laying date and clutch size in two closely related species of hole‐nesting birds

Anders Pape Møller, Javier Balbontin, André A. Dhondt, Vladimir Remeš, Frank Adriaensen, Clotilde Biard, Jordi Camprodon, Mariusz Cichoń, Blandine Doligez, Anna Dubiec, Marcel Eens, Tapio Eeva, Anne E. Goodenough, Andrew G. Gosler, Lars Gustafsson, Philipp Heeb, Shelley A. Hinsley, Staffan Jacob, Rimvydas Juškaitis, Toni Laaksonen, Bernard Leclercq, Bruno Massa, Tomasz D. Mazgajski, Rudi G. Nager, Jan-Åke Nilsson … & Ruedi G. Nager
Coexistence between great tits Parus major and blue tits Cyanistes caeruleus, but also other hole‐nesting taxa, constitutes a classic example of species co‐occurrence resulting in potential interference and exploitation competition for food and for breeding and roosting sites. However, the spatial and temporal variations in coexistence and its consequences for competition remain poorly understood. We used an extensive database on reproduction in nest boxes by great and blue tits based on 87 study plots across...

Data from: Reverse taxonomy applied to the Brachionus calyciflorus cryptic species complex: morphometric analysis confirms species delimitations revealed by molecular phylogenetic analysis and allows the (re)description of four species

Evangelia Michaloudi, Spiros Papakostas, Georgia Stamou, Vilém Neděla, Eva Tihlaříková, Wei Zhang & Steven A. J. Declerck
The discovery and exploration of cryptic species have been profoundly expedited thanks to developments in molecular biology and phylogenetics. In this study, we apply a reverse taxonomy approach to the Brachionus calyciflorus species complex, a commonly studied freshwater monogonont rotifer. By combining phylogenetic, morphometric and morphological analyses, we confirm the existence of four cryptic species that have been recently suggested by a molecular study. Based on these results and according to an exhaustive review of...

Data from: Integrating quantitative morphological and qualitative molecular methods to analyze soil nematode community responses to plant range expansion

Stefan Geisen, L. Basten Snoek, Freddy C. Ten Hooven, Henk Duyts, Olga Kostenko, Janneke Bloem, Henk Martens, Casper W. Quist, Johannes A. Helder & Wim H. Van Der Putten
1. Belowground nematodes are important for soil functioning, as they are ubiquitous and operate at various trophic levels in the soil food web. However, morphological nematode community analysis is time consuming and requires ample training. qPCR-based nematode identification techniques are well available, but high throughput sequencing (HTS) might be more suitable for non-targeted nematode community analysis. 2. We compared effectiveness of qPCR and HTS-based approaches with morphological nematode identification while examining how climate warming-induced plant...

Data from: A high density SNP chip for genotyping great tit (Parus major) populations and its application to studying the genetic architecture of exploration behaviour

Jun-Mo Kim, Anna W. Santure, Henry J. Barton, John L. Quinn, Eleanor F. Cole, Marcel E. Visser, Ben C. Sheldon, Martien A.M. Groenen, Kees Van Oers, Jon Slate & J.-M. Kim
High density SNP microarrays (‘SNP chips’) are a rapid, accurate and efficient method for genotyping several hundred thousand polymorphisms in large numbers of individuals. While SNP chips are routinely used in human genetics and in animal and plant breeding, they are less widely used in evolutionary and ecological research. In this paper we describe the development and application of a high density Affymetrix Axiom chip with around 500 000 SNPs, designed to perform genomics studies...

Data from: Biodiversity-ecosystem functioning relationships in a long-term non-weeded field experiment

Ciska G.F. Veen, Wim Van Der Putten, T. Martijn Bezemer, Wim H. Van Der Putten & G. F. Veen
Many grassland biodiversity experiments show a positive relationship between biodiversity and ecosystem functioning, however, in most these experiments plant communities are established by sowing and natural colonization is prevented by selective weeding of non-sown species. During ecosystem restoration, for example on abandoned fields, plant communities start on bare soil, and diversity is often manipulated in a single sowing event. How such initial plant diversity manipulations influence plant biodiversity development and ecosystem functioning is not well...

Data from: Nematode community responses to range-expanding and native plant communities in original and new range soils

Rutger A. Wilschut, Olga Kostenko, Kadri Koorem & Wim H. Van Der Putten
Many plant species expand their range to higher latitudes in response to climate change. However, it is poorly understood how biotic interactions in the new range differ from interactions in the original range. Here, in a mesocosm experiment, we analyze nematode community responses in original and new range soils to plant communities with either 1) species native in both the original and new range, 2) range-expanding species related to these natives (related range-expanders), or 3)...

Data from: Aquatic omnivores shift their trophic position towards increased plant consumption as plant stoichiometry becomes more similar to their body stoichiometry

Peiyu Zhang, Reinier F. Van Den Berg, Casper H. A. Van Leeuwen, Brigitte A. Blonk & Elisabeth S. Bakker
Human induced eutrophication has strongly altered aquatic ecosystems. With increasing eutrophication, plant nutrient concentrations increase, making them more attractive as food for herbivores. However, most aquatic consumers are omnivorous. Ecological stoichiometry theory predicts that animals prefer to consume food which has a similar nutrient (N and P) composition or C:nutrient ratio compared to their own bodies, hence omnivorous animals may prefer to eat animal prey instead of plants. We ask whether aquatic omnivores would shift...

Data from: The role of plant-soil feedbacks in stabilizing a reindeer-induced vegetation shift in subarctic tundra

Dagmar Egelkraut, Paul Kardol, Jonathan R. De Long & Johan Olofsson
1.Herbivory can drive vegetation into different states of productivity and community composition, and these changes may be stable over time due to historical contingency effects. Interactions with abiotic and biotic soil components can contribute to such long‐term legacies in plant communities through stabilizing positive feedbacks. 2.We studied the role of plant‐soil feedbacks in maintaining vegetation changes caused by historical (~1350‐1900 AD) reindeer herding in northern Sweden. These historical milking grounds (HMGs) consist of meadow plant...

Data from: Increased transgenerational epigenetic variation, but not predictable epigenetic variants, after environmental exposure in two apomictic dandelion lineages

Veronica Preite, Carla Oplaat, Arjen Biere, Jan Kirschner, Wim H. Van Der Putten & Koen J. F. Verhoeven
DNA methylation is one of the mechanisms underlying epigenetic modifications. DNA methylations can be environmentally induced and such induced modifications can at times be transmitted to successive generations. However, it remains speculative how common such environmentally induced transgenerational DNA methylation changes are and if they persist for more than one offspring generation. We exposed multiple accessions of two different apomictic dandelion lineages of the Taraxacum officinale group (Taraxacum alatum and T. hemicyclum) to drought and...

Data from: Variation in home-field advantage and ability in leaf litter decomposition across successional gradients

G.F. Ciska Veen, Ashley D. Keiser, Wim H. Van Der Putten, David A. Wardle & G. F. Ciska Veen
1. It is increasingly recognized that interactions between plants and soil (a)biotic conditions can influence local decomposition processes. For example, decomposer communities may become specialized in breaking down litter of plant species that they are associated with, resulting in accelerated decomposition, known as ‘home-field advantage’ (HFA). Also, soils can vary inherently in their capacity to degrade organic compounds, known as ‘ability’. However, we have a poor understanding how environmental conditions drive the occurrence of HFA...

Data from: Species-specific plant–soil feedbacks alter herbivore-induced gene expression and defense chemistry in Plantago lanceolata

Feng Zhu, Robin Heinen, Martijn Van Der Sluijs, Ciska Raaijmakers, Arjen Biere & T. Martijn Bezemer
Plants actively interact with antagonists and beneficial organisms occurring in the above- and belowground domains of terrestrial ecosystems. In the past decade, studies have focused on the role of plant–soil feedbacks (PSF) in a broad range of ecological processes. However, PSF and its legacy effects on plant defense traits, such as induction of defense-related genes and production of defensive secondary metabolites, have not received much attention. Here, we study soil legacy effects created by twelve...

Data from: Costs and benefits of admixture between foreign genotypes and local populations in the field

Jun Shi, Jasmin Joshi, Katja Tielborger, Koen J. F. Verhoeven & Mirka Macel
Admixture is the hybridization between populations within one species. It can increase plant fitness and population viability by alleviating inbreeding depression and increasing genetic diversity. However, populations are often adapted to their local environments and admixture with distant populations could break down local adaptation by diluting the locally adapted genomes. Thus, admixed genotypes might be selected against and be outcompeted by locally adapted genotypes in the local environments. To investigate the costs and benefits of...

Data from: A plant pathogen modulates the effects of secondary metabolites on the performance and immune function of an insect herbivore

Elena Rosa, Luisa Woestmann, Arjen Biere & Marjo Saastamoinen
Host plant chemical composition critically shapes the performance of insect herbivores feeding on them. Some insects have become specialized on plant secondary metabolites, and even use them to their own advantage such as defense against predators. However, infection by plant pathogens can seriously alter the interaction between herbivores and their host plants. We tested whether the effects of the plant secondary metabolites, iridoid glycosides (IGs), on the performance and immune response of an insect herbivore...

Data from: Gene flow does not prevent personality and morphological differentiation between two blue tit populations

Gabrielle Dubuc-Messier, Samuel P. Caro, Charles Perrier, Kees Van Oers, Denis Reale & Anne Charmantier
Understanding the causes and consequences of population phenotypic divergence is a central goal in ecology and evolution. Phenotypic divergence among populations can result from genetic divergence, phenotypic plasticity or a combination of the two. However, few studies have deciphered these mechanisms for populations geographically close and connected by gene flow, especially in the case of personality traits. In this study, we used a common garden experiment to explore the genetic basis of the phenotypic divergence...

Data from: Effects of admixture in native and invasive populations of Lythrum salicaria

Jun Shi, Mirka Macel, Katja Tielbörger, Koen J.F. Verhoeven & Koen J. F. Verhoeven
Intraspecific hybridization between diverged populations can enhance fitness via various genetic mechanisms. The benefits of such admixture have been proposed to be particularly relevant in biological invasions, when invasive populations originating from different source populations are found sympatrically. However, it remains poorly understood if admixture is an important contributor to plant invasive success and how admixture effects compare between invasive and native ranges. Here, we used experimental crosses in Lythrum salicaria, a species with well-established...

Although the early coral reef-bleaching warning system (NOAA/USA) is established, there is no feasible treatment that can minimize temperature bleaching and/or disease impacts on corals in the field. Here, we present the first attempts to extrapolate the widespread and well-established use of bacterial consortia to protect or improve health in other organisms (e.g., humans and plants) to corals. Manipulation of the coral-associated microbiome was facilitated through addition of a consortium of native (isolated from Pocillopora...

Data from: Phenological mismatch drives selection on elevation, but not on slope, of breeding time plasticity in a wild songbird

Jip J.C. Ramakers, Phillip Gienapp & Marcel E. Visser
Phenotypic plasticity is an important mechanism for populations to respond to fluctuating environments, yet may be insufficient to adapt to a directionally changing environment. To study whether plasticity can evolve under current climate change, we quantified selection and genetic variation in both the elevation (RNE) and slope (RNS) of the breeding time reaction norm in a long-term (1973–2016) study population of great tits (Parus major). The optimal RNE (the caterpillar biomass peak date regressed against...

Data from: Carrying a logger reduces escape flight speed in a passerine bird, but relative logger mass may be a misleading measure of this flight performance detriment

Barbara M. Tomotani, Wender Bil, Henk P. Van Der Jeugd, Remco P.M. Pieters, Florian T. Muijres & Remco P. M. Pieters
1. The recent boost in bird migration studies following the development of various tracking devices raised awareness of how detrimental attaching devices can be for animals. Such effects can occur during migration, but also immediately post-release if the device impairs escape flight performance and, consequently, the bird’s ability to evade predators. 2. In this study, we investigated the effect of carrying a device on the escape flight speed and aerodynamic force production in a migratory...

Data from: Fitting functional responses: direct parameter estimation by simulating differential equations

Benjamin Rosenbaum & Björn Christian Rall
1. The feeding functional response is one of the most widespread mathematical frameworks in Ecology, Marine Biology, Freshwater Biology, Microbiology and related scientific fields describing the resource-dependent uptake of a consumer. Since the exact knowledge of its parameters is crucial to predict, for example, the efficiency of biocontrol agents, population dynamics, food web structure and subsequently biodiversity, a trustworthy parameter estimation method is highly important for scientists using this framework. Classical approaches for estimating functional...

Data from: Interspecific transfer of parasites following a range-shift in Ficedula flycatchers

William Jones, Katarzyna Kulma, Staffan Bensch, Mariusz Cichoń, Anvar Kerimov, Miloš Krist, Toni Laaksonen, Juan Moreno, Pavel Munclinger, Fred Slater, Eszter Szöllősi, Marcel E. Visser, Anna Qvarnström & Fred M. Slater
Human-induced climate change is expected to cause major biotic changes in species distributions and thereby including escalation of novel host-parasite associations. Closely related host species that come into secondary contact are especially likely to exchange parasites and pathogens. Two competing theories, the Enemy Release Hypothesis, where invading hosts escape their original parasites; and the Novel Weapon Hypothesis, where invading hosts bring new parasites that have detrimental effects on native hosts, have been described to predict...

Data from: Temperature effects on prey and basal resources exceed that of predators in an experimental community

Madhav P. Thakur, John N. Griffin, Tom Künne, Susanne Dunker, Andrea Fanesi & Nico Eisenhauer
Climate warming alters the structure of ecological communities by modifying species interactions at different trophic levels. Yet, the consequences of warming-led modifications in biotic interactions at higher trophic levels on lower trophic groups are lesser known. Here, we test the effects of multiple predator species on prey population size and traits, and subsequent effects on basal resources along an experimental temperature gradient (12-15C, 17-20C, and 22-25C). We experimentally assembled food web modules with two congeneric...

Data from: Environmental coupling of heritability and selection is rare and of minor evolutionary significance in wild populations

Jip J.C. Ramakers, Antica Culina, Marcel E. Visser & Phillip Gienapp
Predicting the rate of adaptation to environmental change in wild populations is important for understanding evolutionary change. However, predictions may be unreliable if the two key variables affecting the rate of evolutionary change, heritability and selection, are both affected by the same environmental variable. To determine how general such an environmentally induced coupling of heritability and selection is, and how this may influence the rate of adaptation, we made use of freely accessible, open data...

Data from: Parasitic wasp-associated symbiont affects plant-mediated species interactions between herbivores

Antonino Cusumano, Feng Zhu, Anne-Nathalie Volkoff, Patrick Verbaarschot, Janneke Bloem, Heiko Vogel, Marcel Dicke & Erik H. Poelman
Microbial mutualistic symbiosis is increasingly recognised as a hidden driving force in the ecology of plant–insect interactions. Although plant‐associated and herbivore‐associated symbionts clearly affect interactions between plants and herbivores, the effects of symbionts associated with higher trophic levels has been largely overlooked. At the third‐trophic level, parasitic wasps are a common group of insects that can inject symbiotic viruses (polydnaviruses) and venom into their herbivorous hosts to support parasitoid offspring development. Here, we show that...

Data from: Relative importance of competition and plant-soil feedback, their synergy, context dependency and implications for coexistence

Ylva Lekberg, James D. Bever, Rebecca A. Bunn, Ray M. Callaway, Miranda M. Hart, Stephanie N. Kivlin, John Klironomos, Beau G. Larkin, John L. Maron, Kurt O. Reinhart, Michael Remke, Wim H. Van Der Putten & Ragan M. Callaway
Plants interact simultaneously with each other and with soil biota, yet the relative importance of competition versus plant soil feedback (PSF) on plant performance is poorly understood. Using a meta-analysis of 38 published studies and 150 plant species, we show that effects of interspecific competition (either growing plants with a competitor or singly, or comparing inter- vs. intraspecific competition) and PSF (comparing home vs. away soil, live vs. sterile soil, or control vs. fungicide-treated soil)...
