Data from: Phylogenetic relatedness drives protists assembly in marine and terrestrial environments

Guillaume Lentendu & Micah Dunthorn
Aim: Assembly of protists communities is known to be driven mainly by environmental filtering, but the imprint of phylogenetic relatedness is unknown. In this study, we aim to test the degree at which co-occurrences and co-exclusions of protists in different phylogenetic relatedness classes are deviating from random expectation in two ecosystems in order to link them to ecological processes. Location: Global open-oceans and Neotropical rainforest soils Major taxa: Protists Time period: 2009-2013 Methods: Protist metabarcoding...

Dataset for: Relative contribution of high and low elevation soil microbes and nematodes to ecosystem functioning

Sergio Rasmann, Sarah Semeraro, Alan Kergunteuil, Sara Sánchez-Moreno, Jérémy Puissant, Tim Goodall & Robert Griffiths
Ecosystem productivity is largely dependent on soil nutrient cycling which, in turn, is driven by decomposition rates governed by locally-adapted belowground microbial and invertebrate communities. How climate change will impact soil biota and the correlated ecosystem functioning, however, remains largely an open question. To address this challenge, we first characterized the functional identity of soil microbial and nematode communities originated from the foothills or in the sub-alpine soils of the Alps, and then, using a...

Data from: Adaptations and responses of the common dandelion to low atmospheric pressure in high altitude environments

Carla Arce, Zoe Bont, Ricardo Machado, Paulo Cristaldo & Matthias Erb
Atmospheric pressure is an important, yet understudied factor that may shape plant ecology and evolution. By growing plants under controlled conditions at different experimental stations in the Swiss alps, we evaluated the impact of ecologically realistic atmospheric pressures between 660 and 950 hPa on the growth and defence of different dandelion populations. Low atmospheric pressure was associated with reduced root growth and defensive sesquiterpene lactone production. Defence suppression only occurred in populations originating from lower...

Evolutionary changes in an invasive plant support the defensive role of plant volatiles

Carlos Bustos-Segura, Tiantian Lin, Klaas Vrieling, Diane Laplanche, Peter G. L. Klinkhamer, Yonggen Lou, Leon Bekooy, Thomas Degen, Ted Turlings & Gaylord Desurmont
It is increasingly evident that plants interact with their outside world through the production of volatile organic compounds, but whether the volatiles have evolved to serve in plant defense is still a topic of considerable debate. Unharmed leaves constitutively release small amounts of volatiles, but when the leaves are damaged by herbivorous arthropods, they emit substantially more volatiles. These herbivore-induced plant volatiles (HIPVs) attract parasitoids and predators that kill insect herbivores, and this can benefit...

Prosocial and antisocial choices in a monogamous cichlid with biparental care

Shun Satoh, Redouan Bshary, Momoko Shibasaki, Shumpei Sogawa, Takashi Hotta, Masanori Kohda, Seishiro Inaba & Satoshi Awata
Human society is cooperative and characterized by spontaneous prosociality. Comparative studies on endotherm vertebrates suggest that social interdependence causes the evolution of proactive prosociality. To test the generality of this hypothesis, we modified a prosocial choice task for application to the convict cichlid, Amatitlania nigrofasciata, a monogamous fish with biparental care and a strong pair bond. We show that subject males learned to favor prosocial choices when their mates were the recipients in neighboring tank....

Data from: The effect of community-wide phytochemical diversity on herbivory reverses from low to high elevation

Pilar Fernandez-Conradi, Defossez Emmanuel, Delavallade Adrien, Patrice Descombes, Camille Pitteloud, Gaëtan Glauser, Loïc Pellissier & Sergio Rasmann
1. Theory predicts that a large fraction of phytochemical diversity – the richness of individual chemical compounds produced by plants – governs the complexity of interactions between plants and their herbivores. While the effect of specific classes of chemical compounds on plant resistance against herbivores has been largely documented, the effect of community-level variation in phytochemical diversity on plant-herbivore interactions has so far received minimal consideration. 2. We hypothesized that plant communities bearing on average...

Spatial and temporal heterogeneity in pollinator communities maintains within-species floral odour variation

Mark A. Szenteczki, Adrienne Godschalx, Andrea Galmán, Anahí Espíndola, Marc Gibernau, Nadir Alvarez & Sergio Rasmann
Flowering plants emit complex bouquets of volatile organic compounds (VOCs) to mediate interactions with their pollinators. These bouquets are undoubtedly influenced by pollinator-mediated selection, particularly in deceptively-pollinated species that rely on chemical mimicry. However, many uncertainties remain regarding how spatially and temporally heterogeneous pollinators affect the diversity and distribution of floral odour variation. Here, we characterized and compared the floral odours of ten populations of deceptively-pollinated Arum maculatum (Araceae), and inter-annual and decadal variation in...

No evidence for conspecific recruitment for cooperative hunting in lionfish Pterois miles

Hanaa Sarhan & Redouan Bshary
Lionfish are common piscivores in the Indo-Pacific and invasive in the Caribbean. A fin flaring pattern, involving a rapid undulation of the caudal fin and sequential turning of both pectoral fins, was described in zebra lionfish as a signal to initiate cooperative hunting, and it was hypothesized that such hunting tactics may also exist in other lionfish species and contribute to their successful invasion in the Caribbean. Here, we investigated one of those invasive species,...


Dairazalia Sanchez Cortes, Oya Aran, Marianne Schmid Mast & Daniel Gatica-Perez
The corpus was gathered with the aim of analyzing emergent leadership as a social phenomenon that occurs in newly formed groups. For each group in the corpus, the participants performed the winter survival task. The annotations of the corpus include self-reported and perceived personality, concepts related to leadership, participants’ performance in the survival task, and manual transcriptions from the recordings in English. The full corpus contains approximately 10 hours of audio and video.

Global patterns in bumble bee pollen collection show phylogenetic conservation of diet

Thomas Wood, Guillaume Ghisbain, Pierre Rasmont, David Kleijn, Ivo Raemakers, Christophe Praz, Michael Killewald, Jason Gibbs, Kyle Bobiwash, Mira Boustani, Baptiste Martinet & Denis Michez
1. Bumble bees (Bombus) are a group of eusocial bees with a strongly generalised feeding pattern, collecting pollen from many different botanical families. Though predominantly generalists, some bumble bee species seem to have restricted dietary choices. It is unclear whether restricted diets in bumble bees are inherent or a function of local conditions due to a lack of data for many species across different regions. 2. The objective of this study was to determine whether...

The functional role and diversity of soil nematodes are stronger at high elevation in the lesser Himalayan mountain ranges

Yasmeen Kouser, Ali Shah & Sergio Rasmann
Soil nematodes are a foremost component of terrestrial biodiversity, they display the whole gamut of trophic guilds and life strategies, and by their activity, affect major ecosystem process, such as organic matter degradation and carbon cycling. Based on nematodes’ functional types, nematode community indices have been developed, and can be used to link variation in nematodes community composition and ecosystem processes. Yet, the use of these indices has been mainly restricted to anthropogenic stresses. In...

Cross-continental comparison of parasite communities in a wide-ranging carnivore suggests associations with prey diversity and host density

Astrid Stronen, Barbara Molnar, Paolo Ciucci, Chris Darimont, Lorenza Grottoli, Paul Paquet, Tim Sallows, Judit Smits & Heather Bryan
Parasites are integral to ecosystem functioning yet often overlooked. Improved understanding of host-parasite associations is important, particularly for wide-ranging species for which host range shifts and climate change could alter host-parasite interactions and their effects on ecosystem function. Among the most widely distributed mammals with diverse diets, grey wolves (Canis lupus) host parasites that are transmitted among canids and via prey species. Grey wolf-parasite associations may therefore influence the population dynamics and ecological functions of...
