Data from: Rapid transgenerational effects in Knautia arvensis in response to plant-community diversity

Tanja Rottstock, Volker Kummer, Markus Fischer & Jasmin Joshi
1. Plant-species persistence in natural communities requires coping with biotic and abiotic challenges. These challenges also depend on plant-community composition and diversity. Over time, biodiversity effects have been shown to be strengthened via increasing species complementarity in mixtures. Little is known, however, whether differences in community diversity and composition induce rapid transgenerational phenotypic adaptive differentiation during community assembly. We expect, altered plant-plant and other biotic interactions (mutualists or antagonists) in high vs. low diverse communities...

Data from: Transcriptome profiling of ontogeny in the acridid grasshopper Chorthippus biguttulus

Emma L. Berdan, Jonas Finck, Paul R. Johnston, Isabelle Waurick, Camila J. Mazzoni & Frieder Mayer
Acridid grasshoppers (Orthoptera:Acrididae) are widely used model organisms for developmental, evolutionary, and neurobiological research. Although there has been recent influx of orthopteran transcriptomic resources, many use pooled ontogenetic stages obscuring information about changes in gene expression during development. Here we developed a de novo transcriptome spanning 7 stages in the life cycle of the acridid grasshopper Chorthippus biguttulus. Samples from different stages encompassing embryonic development through adults were used for transcriptomic profiling, revealing patterns of...

Data from: Temporal migration pattern and mating tactics influence size-assortative mating in Rana temporaria

Carolin Dittrich, Ariel Rodríguez, Ori Segev, Sanja Drakulić, Heike Feldhaar, Miguel Vences & Mark-Oliver Rödel
Assortative mating is a common pattern in sexually reproducing species, but the mechanisms leading to assortment remain poorly understood. By using the European common frog (Rana temporaria) as a model, we aim to understand the mechanisms leading to size-assortative mating in amphibians. With data from natural populations collected over several years, we first show a consistent pattern of size-assortative mating across our two study populations. We subsequently ask if assortative mating may be explained by...

Data from: Evolution of defence cocktails: antimicrobial peptide combinations reduce mortality and persistent infection

Caroline Zanchi, Paul R. Johnston & Jens Rolff
The simultaneous expression of costly immune effectors such as multiple antimicrobial peptides is a hallmark of innate immunity of multicellular organisms, yet the adaptive advantage remains unresolved. Here, we test current hypotheses on the evolution of such defence cocktails. We use RNAi gene knock-down to explore, the effects of three highly expressed antimicrobial peptides, displaying different degrees of activity in vitro against Staphylococcus aureus, during an infection in the beetle Tenebrio molitor. We find that...

Data from: Socio-economic impact classification of alien taxa (SEICAT)

Martinou, Wolfgang Nentwig, Jan Pergl, Petr Pyšek, Wolfgang Rabitsch, David M. Richardson, Helen E. Roy, Wolf-Christian Saul, Riccardo Scalera, Montserrat Vila, John R. U. Wilson, Sabina Kumschick & Sabrina Kumschick
Many alien taxa are known to cause socio-economic impacts by affecting the different constituents of human well-being (security; material and non-material assets; health; social, spiritual and cultural relations; freedom of choice and action). Attempts to quantify socio-economic impacts in monetary terms are unlikely to provide a useful basis for evaluating and comparing impacts of alien taxa because they are notoriously difficult to measure and important aspects of human well-being are ignored. Here, we propose a...

Data from: The strength of negative plant-soil feedback increases from the intraspecific to the interspecific and the functional group level

Alexandra R. Bukowski, Conrad Schittko & Jana S. Petermann
1. One of the processes that may play a key role in plant species coexistence and ecosystem functioning is plant-soil feedback, the effect of plants on associated soil communities and the resulting feedback on plant performance. Plant-soil feedback at the interspecific level (comparing growth on own soil with growth on soil from different species) has been studied extensively, while plant-soil feedback at the intraspecific level (comparing growth on own soil with growth on soil from...
