Dataset for: Interactive effects of tree species composition and water availability on growth and direct and indirect defences in Quercus ilex

Andrea Galmán, Carla Vázquez-González, Gregory Röder & Bastien Castagneyrol
Plant diversity has often been reported to decrease insect herbivory in plants. Of the numerous mechanisms that have been proposed to explain this phenomenon, how plant diversity influences plant defences via effects on growth has received little attention. In addition, plant diversity effects may be contingent on abiotic conditions (e.g., resource and water availability). Here, we used a long-term experiment to explore the interactive effects of tree species composition and water availability on growth, direct...

No evidence that lionfish Pterois miles coordinate and reciprocate during hunts

Hanaa Sarhan
Collaborative hunting can be defined as predators coordinating their movements in time and space, assuming different roles in catching prey. As lionfishes are naturally solitary hunters; an experimental study documenting active recruitment, coordination and alternating (potentially reciprocal) striking in dwarf lionfish Dendrochirus zebra received major attention. A hypothesis was that collaborative hunting may contribute to the successful invasion of another lionfish species, Pterois miles, in the Caribbean. A first study on P. miles in the...

Call combinations in chimpanzees: a social tool?

Maël Leroux, Bosco Chandia, Alexandra Bosshard, Klaus Zuberberbuehler & Simon Townsend
A growing body of evidence suggests the capacity for animals to combine calls into larger communicative structures is more common than previously assumed. Despite its cross-taxa prevalence, little is known regarding the evolutionary pressures driving such combinatorial abilities. One dominant hypothesis posits that social complexity and vocal complexity are linked, with changes in social structuring (e.g. group size) driving the emergence of ever-more complex vocal abilities, such as call sequencing. In this paper, we tested...

Nematode epicuticlin and collagen sequences with YGD/GYR amino acid motifs

Bruno Betschart, Marco Bisoffi & Ferial Alaeddine
Nematoda and Arthropoda have a complex exoskeleton, the cuticle, which is replaced via molts during their development. Major constituents of nematode cuticles are specific collagens and insoluble proteins called cuticlins. The epicuticle is composed of an insoluble protein called epicuticlin. Our objective was to identify and characterize genes and their encoded proteins forming the epicuticle. We were able to complete the identification of the first epicuticlin gene, Asu-epic-1 of Ascaris suum which is composed of...

Threats to groundwater quality in the Anthropocene

Christian Moeck & Mario Schirmer
Groundwater quality degradation is a well-recognized phenomenon and has received considerable attention since the industrial revolution. In spite of this, many aspects concerning the understanding and management of groundwater as a resource remain complex, and adequate information, in many cases, remains elusive. Strategies to protect and manage groundwater quality are often based on limited data and thus restricted system knowledge. As questions remain about the behaviour and prediction of well-known groundwater contaminants, new concerns around...

How 2 and 4 year old children coordinate joint actions with peers

Federico Rossano, Jack Terwilliger, Adrian Bangerter, Emilie Genty, Raphaela Heesen & Klaus Zuberbühler
The interaction engine hypothesis postulates a uniquely human ability and motivation for social interaction. A crucial juncture in the ontogeny of the interaction engine could be around 2-4 years of age, but observational studies of children in natural contexts are lacking. Moreover, data on the ontogenetic development of joint action coordination can provide critical human data for comparative research investigating the phylogenetic roots of the interaction engine. In this study we report on focal observations...

Teaching, sharing experience and innovation

Ottilie Tilston, Adrian Bangerter & Kristian Tylén
Teaching is widely understood to have an important role in cultural transmission. But cultural transmission experiments typically do not document or analyse what happens during teaching. Here, we examine the content of teaching during skill transmission under two conditions: in the presence of the artefact (no-displacement condition) and in the absence of the artefact (displacement condition). Participants built baskets from various materials to carry as much rice as possible before teaching the next participant in...

Bioturbation by endogeic earthworms facilitates entomopathogenic nematode movement toward herbivore-damaged maize roots

Sergio Rasmann, Sandrine Fattorre, Zhenggao Xiao, Adrienne Godschalx, Gregory Röder, Ted Turlings & Claire Le Bayon
Entomopathogenic nematodes (EPNs) have been extensively studied as potential biological control agents against root-feeding crop pests. Maize roots under rootworm attack have been shown to release volatile organic compounds, such as (E)-β-caryophyllene (Eβc) that guide EPNs toward the damaging larvae. As yet, it is unknown how belowground ecosystems engineers, such as earthworms, affect the biological control capacity of EPNs by altering the root Eβc-mediated tritrophic interactions. We here asked whether and how, the presence of...

Nutritional stress exacerbates impact of a novel insecticide on solitary bees’ behaviour, reproduction and survival

Anina Knauer, Cedric Alaux, Matthew Allan, Robin Dean, Virginie Dievart, Gaétan Glauser, Tomasz Kiljanek, Denis Michez, Janine Schwarz, Giovanni Tamburini, Dimitry Wintermantel, Alexandra-Maria Klein & Matthias Albrecht
Pesticide exposure and food stress are major threats to bees, but their potential synergistic impacts under field-realistic conditions remain poorly understood and are not considered in current pesticide risk assessments. We conducted a semi-field experiment to examine the single and interactive effects of the novel insecticide flupyradifurone (FPF) and nutritional stress on fitness proxies in the solitary bee Osmia bicornis. Individually marked bees were released into flight cages with monocultures of either buckwheat, wild mustard...

Data: Detecting preservation and reintroduction sites for endangered plant species using a two-step modelling and field approach

Sergio Rasmann, Olivia Rusconi, Olivier Broennimann, Yannick Storrer, Renée-Claire Le Bayon & Antoine Guisan
To withstand the surge of species loss worldwide, (re)introduction of endangered plant species has become an increasingly common technique in conservation biology. Successful (re)introduction plans, however, require identifying sites that provide the optimal ecological conditions for the target species to thrive. In this study, we propose a two-step approach to identify appropriate (re)introduction sites. The first step involves modelling the niche and distribution of the species with bioclimatic and topographical predictors, both at continental and...

Top-down cascading effects of seed-feeding beetles and their parasitoids on plants and leaf herbivores

Maximilien Cuny, Diana La Forgia, Gaylord Desurmont, Carlos Bustos-Segura, Gaetan Glauser & Betty Benrey
When feeding on a plant, herbivorous insects alter the quality of the plant as a food source. This affects other organisms interacting with the same plant. These so-called ‘plant-mediated interactions’ can be altered by parasitoids that attack the herbivores. So far, this research area has mainly focused on interactions at the leaf level, and very little is known about plant-mediated interactions via seeds. It is still poorly understood if seeds that survive insect damage have...

Reconnaître l'utilité publique. Parlementaires et personnel des administrations fiscales face à la philanthropie en Suisse

Alexandre Lambelet, Philip Balsiger, Romain Carnac & Caroline Honegger
Comment définir et délimiter les causes et activités qui relèvent de l'utilité publique et qui méritent d'être encouragées fiscalement ? Les acteurs philanthropiques sont-ils plus légitimes, plus efficaces pour répondre à certains besoins sociaux que l'État ? Ce dernier doit-il se priver d'une partie de ses recettes fiscales pour favoriser le développement de ces pratiques ? Est-il juste de récompenser les dons d'argent quand d'autres gestes altruistes (comme le bénévolat) ne le sont pas ?...

Data from: An integrative skeletal and paleogenomic analysis of stature variation suggests relatively reduced health for early European farmers

Perry
Human culture, biology, and health were shaped dramatically by the onset of agriculture ~12,000 years before present (BP). This shift is hypothesized to have resulted in increased individual fitness and population growth as evidenced by archaeological and population genomic data alongside a decline in physiological health as inferred from skeletal remains. Here, we consider osteological and ancient DNA data from the same prehistoric individuals to study human stature variation as a proxy for health across...

Effect of water availability on volatile-mediated communication between potato plants in response to insect herbivory

Carla Vázquez-González, Laura Pombo-Salinas, Lucia Martín-Cacheda, Sergio Rasmann, Gregory Roeder, Luis Abdala-Roberts, Kailen Mooney & Xoaquin Moreira
Airborne plant communication is a widespread phenomenon in which volatile organic compounds (VOCs) from damaged plants boost herbivore resistance in neighbouring, undamaged plants. Although this form of plant signalling has been reported in more than 30 plant species, there is still a considerable knowledge gap on how abiotic factors (e.g., water availability) alter its outcomes. We performed a greenhouse experiment to test for communication between potato plants (Solanum tuberosum) in response to herbivory by the...
