Data from: Foraging efficiency and size matching in a plant – pollinator community: the importance of sugar content and tongue length

Saskia G.T. Klumpers, Martina Stang & Peter G.L. Klinkhamer
A longstanding question in ecology is how species interactions are structured within communities. Although evolutionary theory predicts close size matching between floral nectar tube depth and pollinator proboscis length of interacting species, such size matching has seldom been shown and explained in multispecies assemblages. Here, we investigated the degree of size matching among Asteraceae and their pollinators and its relationship with foraging efficiency. The majority of pollinators, especially Hymenoptera, choose plant species on which they...

Data from: Nonadditive effects of consumption in an intertidal macroinvertebrate community are independent of food availability but driven by complementarity effects

Emily M. Van Egmond, Peter M. Van Bodegom, Jurgen R. Van Hal, Richard S.P. Van Logtestijn, Matty P. Berg, Rien Aerts & Richard S. P. Van Logtestijn
Suboptimal environmental conditions are ubiquitous in nature and commonly drive the outcome of biological interactions in community processes. Despite the importance of biological interactions for community processes, knowledge on how species interactions are affected by a limiting resource, e.g. low food availability, remains limited. Here, we tested whether variation in food supply causes non-additive consumption patterns, using the macroinvertebrate community of intertidal sandy beaches as a model system. We quantified isotopically labelled diatom consumption by...

Data from: The EGA+GNM framework: an integrative approach to modelling behavioural syndromes

Jordan S. Martin, Jorg J. M. Massen, Vedrana Šlipogor, Thomas Bugnyar, Adrian V. Jaeggi & Sonja E. Koski
1. Behavioural syndromes refer to correlated suites of behavioural traits exhibiting consistent among-individual variation, i.e. personality. Factor analysis (FA) is currently the dominant method for modelling behavioural syndromes in humans and animals. Although FA is useful for inferring the latent causes underlying trait correlations, it does not account for pairwise behavioural interactions that also contribute to syndrome structure. Given that latent factors and pairwise interactions are likely ubiquitous causes of trait covariation, both should be...

Data from: Fitness costs of phoretic nematodes in the burying beetle, Nicrophorus vespilloides

Yin Wang & Daniel E. Rozen
1. Nicrophorus vespilloides is a social beetle that rears its offspring on decomposing carrion. Wild beetles are frequently associated with two types of macrobial symbionts, mites and nematodes. 2. Although these organisms are believed to be phoretic commensals that harmlessly use beetles as a means of transfer between carcasses, the role of these symbionts on N. vespilloides fitness is poorly understood. Here we show that nematodes have significant negative effects on beetle fitness across a...

Data from: Scaling up effects of measures mitigating pollinator loss from local- to landscape-level population responses

David Kleijn, Theo E. W. Linders, Anthonie Stip, Jacobus C. Biesmeijer, Felix L. Wäckers & Tibor Bukovinszky
1. Declining pollinator populations have caused concern about consequences for food production, and have initiated an increasing number of initiatives that aim to mitigate pollinator loss through enhancement of floral resources. Studies evaluating effects of mitigation measures generally demonstrate positive responses of pollinators to floral resource enhancement. However, it remains unclear whether this represents landscape-level population effects or results from a spatial redistribution of individuals from otherwise unaffected populations. 2. Here we present a method...

Data from: Spatial heterogeneity in plant-soil feedbacks alters competitive interactions between two grassland plant species

Wei Xue, Frank Berendse & T. Martijn Bezemer
1. The effects of plants on soil vary greatly between plant species and in mixed plant communities this can lead to spatial variation in plant-soil feedback (PSF) effects. Such spatial effects are thought to influence plant species coexistence, but the empirical evidence for this hypothesis is limited. 2. Here, we investigate how spatial heterogeneity in PSFs influences plant growth and competition. The experiment was carried out with high and low nutrient soils to examine how...

Data from: Fuel moisture content enhances nonadditive effects of plant mixtures on flammability and fire behavior

Luke G. Blauw, Niki Wensink, Lisette Bakker, Richard S. P. Van Logtestijn, Rien Aerts, Nadejda A. Soudzilovskaia & J. Hans C. Cornelissen
Fire behavior of plant mixtures includes a complex set of processes for which the interactive contributions of its drivers, such as plant identity and moisture, have not yet been unraveled fully. Plant flammability parameters of species mixtures can show substantial deviations of fire properties from those expected based on the component species when burnt alone; that is, there are nonadditive mixture effects. Here, we investigated how fuel moisture content affects nonadditive effects in fire behavior....

Data from: Insular woody daisies (Argyranthemum , Asteraceae) are more resistant to drought-induced hydraulic failure than their herbaceous relatives

Larissa C. Doria, Diego S. Podadera, Marcelino Del Arco, Thibaud Chauvin, Erik Smets, Sylvain Delzon & Frederic Lens
1. Insular woodiness refers to the evolutionary transition from herbaceousness towards derived woodiness on (sub)tropical islands, and leads to island floras that have a higher proportion of woody species compared to floras of nearby continents. 2. Several hypotheses have tried to explain insular woodiness since Darwin’s original observations, but experimental evidence why plants became woody on islands is scarce at best. 3. Here, we combine experimental measurements of hydraulic failure in stems (as a proxy...

Data from: Spatial and temporal diversity in hyperparasitoid communities of Cotesia glomerata on garlic mustard, Alliaria petiolata

Robin Heinen & Jeffrey A. Harvey
1. Interactions between two trophic levels can be very intimate, often making species dependent on each other, something that increases with specialisation. Some specialised multivoltine herbivores may depend on multiple plant species for their survival over the course of a growing season, especially if their food plants are short‐lived and grow at different times. Later generations may exploit different plant species from those exploited by previous generations. 2. Multivoltine parasitoids as well as their natural...

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: Ultraviolet radiation exposure time and intensity modulate tomato resistance against herbivory through activation of the jasmonic acid signaling

Rocío Escobar-Bravo, Gang Chen, Hye Kyong Kim, Katharina Grosser, Nicole M. Van Dam, Kirsten A. Leiss, Peter G.L. Klinkhamer & Peter G L Klinkhamer
Ultraviolet (UV) radiation can modulate plant defenses against herbivorous arthropods. We investigated how different UV exposure times and irradiance intensities affected tomato (Solanum lycopersicum) resistance to thrips (Frankliniella occidentalis) by assessing UV effects on thrips-associated damage and host-selection, selected metabolite and phytohormone contents, expression of defense-related genes, and trichome density and chemistry, the latter having dual roles in defense and UV protection. Short UV daily exposure times increased thrips resistance in the cultivar ‘Moneymaker’ but...

Data from: Living on the edge: multiscale habitat selection by cheetahs in a human-wildlife landscape

Britt Klaassen & Femke Broekhuis
Animals select habitats that will ultimately optimise their fitness through access to favourable resources, such as food, mates, and breeding sites. However, access to these resources may be limited by bottom-up effects, such as availability, and top-down effects such as risk avoidance and competition, including that with humans. Competition between wildlife and people over resources, specifically over space, has played a significant role in the worldwide decrease of large carnivores. The goal of this study...

Data from: Plant competition alters the temporal dynamics of plant-soil feedbacks

T. Martijn Bezemer, Jingying Jing, J.M. Tanja Bakx-Schotman, Erik-Jan Bijleveld & J. M. Tanja Bakx-Schotman
1. Most studies on plant-soil feedback (PSF) and plant competition measure the feedback response at one moment only. However, PSFs and competition may both change over time, and how PSF and competition interact over time is unclear. 2. We tested the temporal dynamics of PSF and interspecific competition for the forb Jacobaea vulgaris and the grass Holcus lanatus. We grew both species individually and in interspecific competition in soil that was first conditioned in the...
