Dreissenid mussels (including the zebra mussel Dreissena polymorpha and the quagga mussel D. rostriformis) are among the world's most notorious invasive species, with large and widespread ecological and economic effects. However, their long‐term population dynamics are poorly known, even though these dynamics are critical to determining impacts and effective management. We gathered and analyzed 67 long‐term (>10 yr) data sets on dreissenid populations from lakes and rivers across Europe and North America. We addressed five...

Data from: Gene expression response to a nematode parasite in novel and native eel hosts

Seraina E. Bracamonte, Paul R. Johnston, Michael T. Monaghan & Klaus Knopf
Invasive parasites are involved in population declines of new host species worldwide. The high susceptibilities observed in many novel hosts have been attributed to the lack of protective immunity to the parasites which native hosts acquired during their shared evolution. We experimentally infected Japanese eels (Anguilla japonica) and European eels (A. anguilla) with Anguillicola crassus, a nematode parasite that is native to the Japanese eel and invasive in the European eel. We inferred gene expression...

Data from: Expanding the toolbox of nutrient limitation studies: novel method of soil microbial in-growth bags to evaluate nutrient demands in tropical forests

Tessa Camenzind, Stefan Scheu & Matthias C. Rillig
1.Ecosystem processes and the organisms involved are generally limited by the availability of one or more element in soil, an important phenomenon to consider for our understanding of ecosystem functioning and future changes. Especially in tropical forests, typically growing on nutrient depleted soils, nitrogen (N), phosphorus (P) or other limitations are assumed. However, large‐scale nutrient manipulation experiments revealed complex site‐specific patterns and several authors raised the need for novel approaches to reveal deeper mechanistic insights...

Data from: Statistical context dictates the relationship between feedback-related EEG signals and learning

Matthew R. Nassar, Rasmus Bruckner & Michael J. Frank
Learning should be adjusted according to the surprise associated with observed outcomes but calibrated according to statistical context. For example, when occasional changepoints are expected, surprising outcomes should be weighted heavily to speed learning. In contrast, when uninformative outliers are expected to occur occasionally, surprising outcomes should be less influential. Here we dissociate surprising outcomes from the degree to which they demand learning using a predictive inference task and computational modeling. We show that the...

Within-individual trophic variability drives short-term intraspecific trait variation in natural populations

Camille Musseau, Simone Vincenzi, Frédéric Santoul, Stéphanie Boulêtreau, Dusan Jesensek & Alain Crivelli
1. Intra-specific trait variability (ITV) maintains functional diversity in populations and communities, and plays a crucial role in ecological and evolutionary processes such as trophic cascades or speciation. Furthermore, functional variation within a species and its populations can help buffer against harmful environmental changes. Trait variability within species can be observed from differences among populations, and between- and within individuals. In animals, ITV can be driven by ontogeny, the environment in which populations live, and...

The diverse nature of island isolation and its effect on land-bridge insular faunas

Yuval Itescu, Johannes Foufopoulos, Panayiotis Pafilis & Shai Meiri
Aim Isolation is a key factor in island biology. It is usually defined as the distance to the geographically nearest mainland, but multiple alternatives exist. We explored how testing different isolation indices affects the inference of isolation effects on faunal characteristics. We focused on land-bridge islands and compared the relationships of multiple spatial and temporal (i.e., through time) isolation indices with community-, population-, and individual-level characteristics (species richness, population density, and body size, respectively). Location...

Data from: An empirical assessment of a single family-wide hybrid capture locus set at multiple evolutionary timescales in Asteraceae

Premise of the study: Hybrid capture with high-throughput sequencing (Hyb-Seq) is a powerful tool for evolutionary studies. The applicability of an Asteraceae family-specific Hyb-Seq method and the outcomes of different phylogenetic analyses are assessed. Methods: Hyb-Seq data from 112 Asteraceae samples were organized into groups at different taxonomic levels (tribe, genus, and species). For each group, datasets of non-paralogous loci were built and proportions of parsimony informative characters estimated. The impacts of the analyzing alternative...
