Soil inoculation alters leaf metabolic profiles in genetically identical plants

Martine Huberty
Abiotic and biotic properties of soil can influence growth and chemical composition of plants. Although it is well-known that soil microbial composition can vary greatly spatially, how this variation affects plant chemical composition is poorly understood. We grew genetically identical Jacobaea vulgaris in sterilized soil inoculated with live soil collected from four natural grasslands and in 100% sterilized soil. Within each grassland we sampled eight plots, totalling 32 different inocula. Two samples per plot were...

Data from: Microbiomes of a specialist caterpillar are consistent across different habitats but also resemble the local soil microbial communities

Sofia Gomes, Anna Kielak, Emilia Hannula, Heinen Robin, Renske Jongen, Ivor Keesmaat, Jon Delong & Martijn Bezemer
Background: Insect-associated microorganisms can provide a wide range of benefits to their host, but insect dependency on these microbes varies greatly. The origin and functionality of insect microbiomes is not well understood. Many caterpillars can harbor symbionts in their gut that impact host metabolism, nutrient uptake and pathogen protection. Despite our lack of knowledge on the ecological factors driving microbiome assemblages of wild caterpillars, they seem to be highly variable and influenced by diet and...

Data from: Population- and species-based variation of webworm-parasitoid interactions in hogweeds (Heracelum spp.) in the Netherlands

Jeffrey Harvey, Rieta Gols & Paul Ode
In three Dutch populations of the native small hogweed (Heracleum sphondylium), and one of the invasive giant hogweed (H. mantegazzianum), interactions between a specialist herbivore, the parsnip webworm (Depressaria radiella), and its associated parasitoids were compared during a single growing season. We found plant population and/or host plant species-related differences in the abundance of moth pupae, the specialist polyembryonic endoparasitoid, Copidosoma sosares, the specialist pupal parasitoid, Barichneumon heracliana, and a potential hyperparasitoid of C. sosares,...

Data from: Adapted dandelions trade dispersal for germination upon root herbivore attack

Zoe Bont, Marc Pfander, Christelle Robert, Meret Huber, Erik Poelman, Ciska Raaijmakers & Matthias Erb
A plant’s offspring may escape unfavourable local conditions through seed dispersal. Whether plants use this strategy to escape insect herbivores is not well understood. Here, we explore how different dandelion (Taraxacum officinale agg.) populations, including diploid outcrossers and triploid apomicts, modify seed dispersal in response to root herbivore attack by their main root-feeding natural enemy, the larvae of the common cockchafer Melolontha melolontha. In a manipulative field experiment, root herbivore attack increased seed dispersal potential...

Reduced avian body condition due to global warming has little reproductive or population consequences

Nina McLean, Henk Van Der Jeugd, Chris Van Turnhout, Jonathan Lefcheck & Martijn Van De Pol
Climate change has strong effects on traits such as phenology and physiology. Studies typically assume that climate-induced trait changes will have consequences for population dynamics, but explicit tests are rare. Body condition reflects energy storage and may directly affect how much can be invested in reproduction and survival. However, the causal pathway by which decreased body condition impacts population dynamics has never been quantified across multiple populations and species. Therefore, we lack a general understanding...

Data from: Shading enhances plant species richness and diversity on an extensive green roof

Henk-Jan Van Der Kolk, Petra Van Den Berg, Gerard Korthals & Martijn Bezemer
Green roofs can promote biodiversity in urban areas. The extent to which green roofs stimulate plant diversity can depend on roof characteristics such as roof age, substrate depth and shading. We exploratively studied the vegetation on a Dutch green roof in 50 permanent plots (1 m2) over eight years (2012–2019) following roof construction. Plots were situated either on low substrate depth (6 cm light-weight extensive substrate) or high substrate depth (6 cm light-weight extensive substrate...

Data from: Tracking temperate fish reveals their relevance for plant seed dispersal

Andrea J.E. Mulder, Roland Van Aalderen & Casper H.A. Van Leeuwen
Seed dispersal is a fundamental process for plant communities, especially now that our changing world demands rapid colonization of new habitats. Long-distance dispersal is especially important for plant population persistence and range expansions. The contribution of fishes to plant seed dispersal in aquatic ecosystems (ichthyochory) has long been overlooked. Although we know fish disperse seeds, it is largely unknown where, when and how far – especially in temperate regions. Here we studied the potential of...

Community-level interactions between plants and soil biota during range expansion

Kadri Koorem, Basten Snoek, Janneke Bloem, Stefan Geisen, Olga Kostenko, Marta Manrubia, Kelly Ramirez, Carolin Weser, Rutger Wilschut & Wim Van Der Putten
1. Plant species that expand their range in response to current climate change will encounter soil communities that may hinder, allow, or even facilitate plant performance. It has been shown repeatedly for plant species originating from other continents that these plants are less hampered by soil communities from the new than from the original range. However, information about the interactions between intra-continental range expanders and soil communities is sparse, especially at community level. 2. Here...

Data from: Above-belowground linkages of functionally dissimilar plant communities and soil properties in a grassland experiment

Katja Steinauer, Robin Heinen, Renske Jongen, Emilia Hannula, Martine Huberty, Jon Delong, Minggang Wang & Martijn Bezemer
Changes in plant community composition can have long-lasting consequences for ecosystem functioning. However, how the duration of plant growth of functionally distinct grassland plant communities influences abiotic and biotic soil properties and thus ecosystem functions is poorly known. In a field experiment, we established identical experimental subplots in two successive years comprising of fast- or slow-growing grass and forb community mixtures with different forb:grass ratios. After one and two years of plant growth, we measured...

Centaurea population effects on nematode communities

Rutger Wilschut, Kim Magnée, Stefan Geisen, Wim Van Der Putten & Olga Kostenko
Data set belonging to the study 'Plant population and soil origin effects on nematode community composition in the rhizosphere of a range-expanding plant species and a native congener'. In this study, we experimentally compared the development of nematode communities originating from northern and southern European soils in the rhizospheres of different populations of the range-expanding plant species Centaurea stoebe and the native plant species Centaurea jacea. The experiment was carried out in a greenhouse of...

Data from: Innate and adaptive immune proteins in the preen gland secretions of male house sparrows

Diana Carneiro, Gábor A Czirják & Melissah Rowe
Recent studies have demonstrated that preen oil acts to reduce or eliminate feather-associated bacteria. The mechanisms underlying this antibacterial activity, however, are incompletely understood. In addition to the activity of alcohols (i.e. 3,7-dimethyloctan-1-ol), recent research has suggested that antimicrobial peptides may underlie the antibacterial activity of preen oil. Here, we document the presence of innate and adaptive immune proteins, lysozyme and immunoglobulin Y (IgY), in the preen oil of house sparrows (Passer domesticus). We suggest...

Code and data for: Familiarity breeds success: pairs that meet earlier experience increased breeding performance in a wild bird population

Antica Culina, Josh Firth & Camilla Hinde
This is a Data package that contains three separate datasets and the analysis code for a manuscript 'Familiarity breeds success: pairs that meet earlier experience increased breeding performance in a wild bird population '. The first Dataset (pairs_data_2007_10) and the second dataset (pairs_data_2011_14) contain the data used to analyse the influence of meeting time of a pair of Great tits (i.e. month in the first dataset, week in the second dataset, when a pair was...

Frugivory underpins the nitrogen cycle

Nacho Villar, Claudia Paz, Valesca Zipparro, Sergio Nazareth, Leticia Bulascoschi, Elisabeth Bakker & Mauro Galetti
1. Tropical rainforests are populated by large frugivores that feed upon fruit-producing woody species, yet their role in regulating the cycle of globally important biogeochemical elements such as nitrogen is still unknown. This is particularly relevant because tropical forests play a prominent role in the nitrogen cycle and are becoming rapidly defaunated. Furthermore, frugivory is not considered in current plant-large herbivore-nutrient cycling frameworks exclusively focused on grazers and browsers. 2. Here we used a long-term...

Modeling multipartite virus evolution: the genome formula facilitates rapid adaptation to heterogeneous environments

Mark Peter Zwart, Mark Zwart & Santiago Elena
Multipartite viruses have two or more genome segments, and package different segments into different particle types. Although multipartition is thought to have a cost for virus transmission, its benefits are not clear. Recent experimental work has shown that the equilibrium frequency of viral genome segments, the setpoint genome formula (SGF), can be unbalanced and host-species dependent. These observations have reinvigorated the hypothesis that changes in genome-segment frequencies can lead to changes in virus-gene expression that...

Ectothermic omnivores increase herbivory in response to rising temperature

Peiyu Zhang, Casper Van Leeuwen, Dagmar Bogers, Marjolein Poelman, Ju Xu, Elisabeth Bakker, Casper H. A. Van Leeuwen, Marjolein Poelma, Jun Xu & Elisabeth S. Bakker
Higher temperatures as a consequence of global climate change may considerably alter trophic interactions. Ectothermic herbivores and carnivores generally ingest more food with rising temperature as their metabolic rates increase with rising temperature. However, omnivorous ectotherms may respond in two ways: quantitatively by consuming more food and qualitatively by altering their degree of herbivory or carnivory through a diet shift. We hypothesize that rising temperature will increase herbivory of ectothermic omnivores as herbivory increases towards...

Data from: Plant community composition steers grassland vegetation via soil legacy effects

Robin Heinen, Emilia Hannula, Jonathan De Long, Martine Huberty, Renske Jongen, Anna Kielak, Katja Steinauer, Feng Zhu & Martijn Bezemer
Soil legacy effects are commonly highlighted as drivers of plant community dynamics and species co-existence. However, experimental evidence for soil legacy effects of conditioning plant communities on responding plant communities under natural conditions is lacking. We conditioned 192 grassland plots using six different plant communities with different ratios of grasses and forbs and for different durations. Soil microbial legacies were evident for soil fungi, but not for soil bacteria, while soil abiotic parameters did not...

Interactive effects of rising temperature and nutrient enrichment on aquatic plant growth, stoichiometry, and palatability

Peiyu Zhang, Ayumi Kuramae, Casper Van Leeuwen, Mandy Velthuis, Ellen Van Donk, Jun Xu & Elisabeth Bakker
The abundance and stoichiometry of aquatic plants are crucial for nutrient cycling and energy transfer in aquatic ecosystems. However, the interactive effects of multiple global environmental changes, including temperature rise and eutrophication, on aquatic plant stoichiometry and palatability remain largely unknown. Here, we hypothesized that (1) plant growth rates increase faster with rising temperature in nutrient-rich than nutrient-poor sediments; (2) plant carbon (C): nutrient ratios (nitrogen (N) and phosphorus (P)) respond differently to rising temperatures...

Fungal root-endophytes influence plants in a species-specific manner that depends on plant's growth stage

Stefan Geisen, Freddy Ten Hooven, Olga Kostenko, Basten Snoek & Wim Van Der Putten
The mycobiome (fungal microbiome) influences plants— from seed germination to full maturation. While many studies on fungal-plant interaction studies have focused on known mutualistic and pathogenic fungi, the functional role of ubiquitous endophytic fungi remains little explored. We examined how root-inhabiting fungi (endophytes) influence range expanding plant species. We isolated endophytes from three European intra-continental range-expanders and three congenerics that are native both in the range-expander’s original (southern Europe) and new (northern Europe) range. To...

Data from: Nocturnal foraging lifts time-constraints in winter for migratory geese but hardly speeds up fueling

Thomas Lameris, Adriaan Dokter, Henk Van Der Jeugd, Willem Bouten, Jasper Koster, Stefan Sand, Coen Westerduin & Bart Nolet
Climate warming advances the optimal timing of breeding for many animals. For migrants to start breeding earlier, a concurrent advancement of migration is required, including pre-migratory fueling of energy reserves. We investigate whether barnacle geese are time-constrained during pre-migratory fueling and whether there is potential to advance or shorten the fueling period to allow an earlier migratory departure. We equipped barnacle geese with GPS-trackers and accelerometers to remotely record birds’ behavior, from which we calculated...

Data from: Connecting the data landscape of long-term ecological studies: the SPI-Birds data hub

Antica Culina, Zuzana Zajkova, Stefan Vriend, Chloé Nater & Liam Bailey
1. The integration and synthesis of the data in different areas of science is drastically slowed and hindered by a lack of standards and networking programmes. Long-term studies of individually marked animals are not an exception. These studies are especially important as instrumental for understanding evolutionary and ecological processes in the wild. Further, their number and global distribution provides a unique opportunity to assess the generality of patterns and to address broad-scale global issues (e.g....

Exogenous application of plant hormones in the field alters aboveground plant–insect responses and belowground nutrient availability, but does not lead to differences in plant–soil feedbacks

Robin Heinen, Katja Steinauer, Jonathan De Long, Renske Jongen, Arjen Biere, Jeffrey Harvey & Martijn Bezemer
Plant–soil feedbacks of plants that are exposed to herbivory have been shown to differ from those of plants that are not exposed to herbivores. Likely, this process is mediated by jasmonic acid (JA) and salicylic acid (SA) defense pathways, which are induced by aboveground herbivory. Furthermore, exogenous application of these phytohormones to plants alters belowground communities, but whether this changes plant–soil feedbacks in natural systems is unknown. We applied exogenous sprays of JA and SA...

Species identity and diversity effects on invasion resistance of tropical freshwater plant communities

Antonella Petruzzella, Tauany A. Da S. S. R. Rodrigues, Casper H. A. Van Leeuwen, Francisco De Assis Esteves, Marcos Paulo Figueiredo-Barros & Elisabeth S. Bakker
Biotic resistance mediated by native plant diversity has long been hypothesized to reduce the success of invading plant species in terrestrial systems in temperate regions. However, still little is known about the mechanisms driving invasion patterns in other biomes or latitudes. We help to fill this gap by investigating how native plant community presence and diversity, and the presence of native phylogenetically closely related species to an invader, would affect invader Hydrilla verticillata establishment success...

Concurrent shifts in wintering distribution and phenology in migratory swans

Rascha Nuijten, Kevin Wood, Eileen Rees & Bart Nolet
Range shifts and phenological change are two processes by which organisms respond to environmental warming. Understanding the mechanisms that drive these changes is key for optimal conservation and management. Here we study both processes in the migratory Bewick’s swan (Cygnus columbianus bewickii) using different methods, analysing nearly 50 years of resighting data (1970-2017). In this period the wintering area of the Bewick’s swans shifted eastwards (“short-stopping”) at a rate of >12.5 km y-1, thereby shortening...

Data from: Microbial and volatile profiling of soils suppressive to Fusarium culmorum of wheat

Adam Ossowicki, Vittorio Tracanna, Marloes L. C. Petrus, Gilles Van Wezel, Jos M. Raaijmakers, Marnix H. Medema & Paolina Garbeva
In disease-suppressive soils, microbiota protect plants from root infections. Bacterial members of this microbiota have been shown to produce specific molecules that mediate this phenotype. To date, however, studies have focused on individual suppressive soils and the degree of natural variability of soil suppressiveness remains unclear. Here, we screened a large collection of field soils for suppressiveness to Fusarium culmorum using wheat (Triticum aestivum) as a model host plant. A high variation of disease suppressiveness...

Volatiles of bacteria associated with parasitoid habitats elicit distinct olfactory responses in an aphid parasitoid and its hyperparasitoid

Tim Goelen, Islam S. Sobhy, Christophe Vanderaa, Jetske G. De Boer, Frank Delvigne, Frédéric Francis, Felix Wäckers, Hans Rediers, Kevin J. Verstrepen, Tom Wenseleers, Hans Jacquemyn & Bart Lievens
1. To locate mating partners and essential resources such as food, oviposition sites and shelter, insects rely to a large extent on chemical cues. While most research has focused on cues derived from plants and insects, there is mounting evidence that indicates that microorganisms emit volatile compounds that may play an important role in insect behaviour. 2. In this study, we assessed how volatile compounds emitted by phylogenetically diverse bacteria affected the olfactory response of...
