Manipulation of photoperiod perception advances gonadal growth but not laying date in the great tit

Lucia Salis, Samuel Caro, Roelof A. Hut, Louis Vernoij & Marcel E. Visser
In seasonal environments, organisms use biotic and abiotic cues to time various biological processes that are crucial for growth, survival and reproductive success. Photoperiod is the best-known cue used to regulate gonadal development, migration and moult of many animal species. In birds, the relationship between photoperiod and gonadal development is clearly established, but we have little understanding on whether photoperiod also regulates actual timing of egg laying under natural conditions. Elucidating the link between photoperiod...

Comparing two measures of phenological synchrony in a predator–prey interaction: simpler works better

Jip J.C. Ramakers, Phillip Gienapp & Marcel E. Visser
1. Global climate change has sparked a vast research effort into the demographic and evolutionary consequences of mismatches between consumer and resource phenology. Many studies have used the difference in peak dates to quantify phenological synchrony (match in dates, MD), but this approach has been suggested to be inconclusive, since it does not incorporate the temporal overlap between the phenological distributions (match in overlap, MO). 2. We used 24 years of detailed data on the...

Less is more: on-board lossy compression of accelerometer data increases biologging capacity

Rascha Nuijten, Theo Gerrits, Judy Shamoun-Baranes & Bart Nolet
GPS-tracking devices have been used in combination with a wide range of additional sensors to study animal behaviour, physiology and interaction with their environment. Tri-axial accelerometers allow researchers to remotely infer the behaviour of individuals, at all places and times. Collection of accelerometer data is relatively cheap in terms of energy usage, but the amount or raw data collected generally requires much storage space and is particularly demanding in terms of energy needed for data...

Data from: Warming enhances sedimentation and decomposition of organic carbon in shallow macrophyte-dominated systems with zero net effect on carbon burial

Mandy Velthuis, Sarian Kosten, Ralf Aben, Garabet Kazanjian, Sabine Hilt, Edwin T. H. M. Peeters, Ellen Van Donk & Elisabeth S. Bakker
Temperatures have been rising throughout recent decades and are predicted to rise further in the coming century. Global warming affects carbon cycling in freshwater ecosystems, which both emit and bury substantial amounts of carbon on a global scale. Currently, most studies focus on the effect of warming on overall carbon emissions from freshwater ecosystems, while net effects on carbon budgets may strongly depend on burial in sediments. Here, we tested whether year‐round warming increases the...

Data from: Foliar-feeding insects acquire microbiomes from the soil rather than the host plant

S. Emilia Hannula, Feng Zhu, Robin Heinen & T. Martijn Bezemer
Microbiomes of soils and plants are linked, but how this affects microbiomes of aboveground herbivorous insects is unknown. We first generated plant-conditioned soils in field plots, then reared leaf-feeding caterpillars on dandelion grown in these soils, and then assessed whether the microbiomes of the caterpillars were attributed to the conditioned soil microbiomes or the dandelion microbiome. Microbiomes of caterpillars kept on intact plants differed from those of caterpillars fed detached leaves collected from plants growing...

Data from: Resting metabolic rate in migratory and non-migratory geese following range expansion; go south, go low

Götz Eichhorn, Manfred R. Enstipp, Jean-Yves Georges, Dennis Hasselquist & Bart A. Nolet
While many species suffer from human activities, some like geese benefit and may show range expansions. In some cases geese (partially) gave up migration and started breeding at wintering and stopover grounds. Range expansion may be facilitated and accompanied by physiological changes, especially when associated with changes in migratory behaviour. Interspecific comparisons found that migratory tendency is associated with a higher basal or resting metabolic rate (RMR). We compared RMR of individuals belonging to a...

Data from: Nonlinear responses of soil nematode community composition to increasing aridity

Dan Xiong, Cunzheng Wei, Jasper Wubs, G. F. Veen, Wenju Liang, Xiaobo Wang, Qi Li, Wim Van Der Putten & Xingguo Han
Aim: Increasing aridity under global change is predicted to have a profound impact on the structure and functioning of terrestrial ecosystems, yet we have poor understanding of how belowground communities respond. In order to understand the longer-term responses of different trophic levels in the soil food web to increasing aridity, we investigated the abundance, richness and community similarity of the soil nematode community along a 3200-km aridity gradient. Location: A transect across semi-arid and arid...

Data from: Personality and gonadal development as sources of individual variation in response to GnRH challenge in female great tits

Samuel P. Caro, Charlotte A. Cornil, Kees Van Oers & Marcel E. Visser
Seasonal timing of reproduction is a key life-history trait, but we know little about the mechanisms underlying individual variation in female endocrine profiles associated with reproduction. In birds, 17β-estradiol is a key reproductive hormone that links brain neuroendocrine mechanisms, involved in information processing and decision making, to downstream mechanisms in the liver, where egg-yolk is produced. Here we test, using a simulated induction of the reproductive system through a GnRH-challenge, whether the ovary of pre-breeding...

Plant traits shape soil legacy effects on individual plant-insect interactions

Robin Heinen, Arjen Biere & Martijn Bezemer
Plant-mediated soil legacy effects can be important determinants of the performance of plants and their aboveground insect herbivores, but so far, soil legacy effects on plant-insect interactions have been tested for only a limited number of host plant species and soils. Here, we tested the performance of a polyphagous aboveground herbivore, caterpillars of the cabbage moth, Mamestra brassicae on twelve host plant species that were grown on a set of soils conditioned by each of...

Shorebird feeding specialists differ in how environmental conditions alter their foraging time

Henk-Jan Van Der Kolk, Bruno J. Ens, Kees Oosterbeek, Willem Bouten, Andrew M. Allen, Magali Frauendorf, Thomas K. Lameris, Thijs Oosterbeek, Symen Deuzeman, Kelly De Vries, Eelke Jongejans & Martijn Van De Pol
Feeding specialisation is a common cause of individual variation. Fitness payoffs of specialisation vary with environmental conditions, but the underlying behavioural mechanisms are poorly understood. Such mechanistic knowledge, however, is crucial to reliably predict responses of heterogeneous populations to environmental change. We quantified spatiotemporal allocation of foraging behaviour in wintering Eurasian oystercatchers (Haematopus ostralegus), a species in which feeding specialisation can be inferred from bill shape. We combined GPS and accelerometer data to quantify foraging...

Data from: Highest plasticity of carbon concentrating mechanisms in earliest evolved phytoplankton

Dedmer B. Van De Waal, Karen M. Brandenburg, Joost Keuskamp, Scarlett Trimborn, Sebastian Rokitta, Sven Alexander Kranz & Björn Rost
Phytoplankton photosynthesis strongly relies on the operation of carbon‐concentrating mechanisms (CCMs) to accumulate CO2 around their carboxylating enzyme ribulose‐1,5‐bisphosphate carboxylase/oxygenase (RuBisCO). Earlier evolved phytoplankton groups were shown to exhibit higher CCM activities to compensate for their RuBisCO with low CO2 specificities. Here, we tested whether earlier evolved phytoplankton groups also exhibit a higher CCM plasticity. To this end, we collected data from literature and applied a Bayesian linear meta‐analytic model. Our results show that with...

Data from: Soil functional responses to drought under range-expanding and native plant communities

Marta Manrubia, Wim Van Der Putten, Carolin Weser, Freddy Ten Hooven, Henk Martens, Pella Brinkman, Stefan Geisen, Kelly Ramirez & Ciska Veen
1. Current climate warming enables plant species and soil organisms to expand their range to higher latitudes and altitudes. At the same time, climate change increases the incidence of extreme weather events such as drought. While it is expected that plants and soil organisms originating from the south are better able to cope with drought, little is known about the consequences of their range shifts on soil functioning under drought events. 2. Here, we test...

Data from: Ultra-long telomeres shorten with age in nestling great tits but are static in adults and mask attrition of short telomeres

Els Atema, Ellis Mulder, Arie J. Van Noordwijk & Simon Verhulst
Telomere length (TL) is increasingly used as a biomarker of senescence, but measuring telomeres remains a challenge. Within tissue samples, TL varies between cells and chromosomes. Class I telomeres are (presumably static) interstitial telomeric sequences, and terminal telomeres have been divided in shorter (Class II) telomeres and ultra-long (Class III) telomeres, and the presence of the latter varies strongly between species. Class II telomeres typically shorten with age, but little is known of Class III...

Data from: Meta-analysis reveals enhanced growth of marine harmful algae from temperate regions with warming and elevated CO2 levels

Karen M. Brandenburg, Mandy Velthuis & Dedmer B. Van De Waal
Elevated pCO2 and warming may promote algal growth and toxin production, and thereby possibly support the proliferation and toxicity of HABs. Here, we tested whether empirical data supports this hypothesis using a meta-analytic approach and investigated the responses of growth rate and toxin content or toxicity of numerous marine and estuarine HAB species to elevated pCO2 and warming. Most of the available data on HAB responses towards the two tested climate change variables concerns dinoflagellates,...

Data from Soil chemistry turned upside down: a meta-analysis of invasive earthworm effects on soil chemical properties

Olga Ferlian, Madhav P. Thakur, Alejandra Castañeda González, Layla M. San Emeterio, Susanne Marr, Barbbara Da Silva Rocha & Nico Eisenhauer
Recent studies have shown that invasive earthworms can dramatically reduce native biodiversity, both above and below the ground. However, we still lack a synthetic understanding of the underlying mechanisms behind these changes, such as whether earthworm effects on soil chemical properties drive such relationships. Here, we investigated the effects of invasive earthworms on soil chemical properties (pH, water content, and the stocks and fluxes of carbon, nitrogen, and phosphorus) by conducting a meta-analysis. Invasive earthworms...

Artificial light at night, in interaction with spring temperature, modulates timing of reproduction in a passerine bird

Davide M. Dominoni, Johan Kjellberg Jensen, Maaike De Jong, Marcel E. Visser & Kamiel Spoelstra
The ecological impact of artificial light at night (ALAN) on phenological events such as reproductive timing is increasingly recognized. In birds, previous experiments under controlled conditions showed that ALAN strongly advances gonadal growth, but effects on egg-laying date are less clear. In particular, effects of ALAN on timing of egg-laying are found to be year-dependent, suggesting an interaction with climatic conditions such as spring temperature, which is known have strong effects on the phenology of...

Data from: More salt, please: global patterns, responses, and impacts of foliar sodium in grasslands

Elizabeth T. Borer, Eric M. Lind, Jennifer Firn, Eric W. Seabloom, T. Michael Anderson, Elizabeth S. Bakker, Lori Biederman, Kimberly J. La Pierre, Andrew S. MacDougall, Joslin L. Moore, Anita C. Risch, Martin Schutz & Carly J. Stevens
Sodium is unique among abundant elemental nutrients, because most plant species do not require it for growth or development, whereas animals physiologically require sodium. Foliar sodium influences consumption rates by animals and can structure herbivores across landscapes. We quantified foliar sodium in 201 locally abundant, herbaceous species representing 32 families and, at 26 sites on four continents, experimentally manipulated vertebrate herbivores and elemental nutrients to determine their effect on foliar sodium. Foliar sodium varied taxonomically...

Data from: Interactions between functionally diverse fungal mutualists inconsistently affect plant performance and competition

Madhav P. Thakur, Vera Quast, Nichole M. Van Dam, Nico Eisenhauer, Christiane Roscher, Arjen Biere & Ainhoa Martinez-Medina
Plants form mutualistic relationship with a variety of belowground fungal species. Such a mutualistic relationship can enhance plant growth and resistance to pathogens. Yet, we know little about how interactions between functionally diverse groups of fungal mutualists affect plant performance and competition. We experimentally determined the effects of interaction between two functional groups of belowground fungi that form mutualistic relationship with plants, arbuscular mycorrhizal (AM) fungi and Trichoderma, on interspecific competition between pairs of closely...

Data from: Sensitivity of global soil carbon stocks to combined nutrient enrichment

Thomas W. Crowther, Charlotte Riggs, Eric M. Lind, Elizabeth T. Borer, Eric W. Seabloom, Sarah E. Hobbie, E. R. Jasper Wubs, Peter B. Adler, Jennifer Firn, Laureano Gherardi, Nicole Hagenah, Kirsten S. Hofmockel, Johannes M. H. Knops, Rebecca L. McCulley, Andrew MacDougall, Pablo L. Peri, Suzanne M. Prober, Carly J. Stevens & Devin Routh
Soil stores approximately twice as much carbon as the atmosphere and fluctuations in the size of the soil carbon pool directly influence climate conditions. We used the Nutrient Network global change experiment to examine how anthropogenic nutrient enrichment might influence grassland soil carbon storage at a global scale. In isolation, enrichment of nitrogen and phosphorous had minimal impacts on soil carbon storage. However, when these nutrients were added in combination with potassium and micronutrients, soil...

Data from: Cumulative energetic costs of military aircraft, recreational and natural disturbance in roosting shorebirds

Henk-Jan Van Der Kolk, K. L. Krijgsveld, H. Linssen, R. Diertens, D. Dolman, M. Jans, M. Frauendorf, B. J. Ens & M. Van De Pol
Knowing the consequences of disturbance for multiple species and all disturbance sources is crucial to mitigate disturbance impacts in densely populated areas. However, studies that observe the complete disturbance landscape to estimate cumulative costs of disturbance are scarce. Therefore, we quantified responses, frequencies and energetic costs of disturbance of four shorebird species on five high tide roosts in the Wadden Sea. Roosts were located either in a military air force training area or were predominantly...

Data from: Disturbance regulates the density–body mass relationship of soil fauna

Frank Van Langevelde, Vincent Comor, Steven De Bie, Herbert Prins & Madhav Thakur
Theory on the density-body mass (DBM) relationship predicts that the density of animal species decreases by the power of −0.75 per unit increase in their body mass, or by the power of −1 when taxa across trophic levels are studied. This relationship is, however, largely debated as the slope often deviates from the theoretical predictions. Here, we tested the ability of the DBM relationship to reflect changes in the structure of communities subjected to an...

Rhizosphere and litter feedbacks to range-expanding plant species and related natives

Marta Manrubia, Wim H. Van Der Putten, Carolin Weser & Ciska Veen
1. Plant-soil feedback (PSF) results from the net legacy effect that plants leave in the composition of soil communities and abiotic soil properties. PSF is induced by the rhizosphere and by litter inputs into the soil, however, we have little understanding of their individual contributions. Here, we examine feedback effects from the rhizosphere of living plants, decomposing litter, and their combination. 2. We used four pairs of climate warming-induced range-expanding plant species and congeneric natives,...
