Data from: Climatic niche evolution is faster in sympatric than allopatric lineages of the butterfly genus Pyrgus

Understanding how speciation relates to ecological divergence has long fascinated biologists. It is assumed that ecological divergence is essential to sympatric speciation, as a mechanism to avoid competition and eventually lead to reproductive isolation, while divergence in allopatry is not necessarily associated with niche differentiation. The impact of the spatial context of divergence on the evolutionary rates of abiotic dimensions of the ecological niche has rarely been explored for an entire clade. Here, we compare...

Data from: Stacked Bt maize and arthropod predators – exposure to insecticidal Cry proteins and potential hazards

Zdeňka Svobodová, Yinghua Shu, Oxana Skoková Habuštová, Jörg Romeis & Michael Meissle
Genetically engineered (GE) crops with stacked insecticidal traits expose arthropods to multiple Cry proteins from Bacillus thuringiensis (Bt). One concern is that the different Cry proteins may interact and lead to unexpected adverse effects on non-target species. Bi- and tri-trophic experiments with SmartStax maize, herbivorous spider mites (Tetranychus urticae) and aphids (Rhopalosiphum padi), and predatory spiders (Phylloneta impressa), ladybeetles (Harmonia axyridis), and lacewings (Chrysoperla carnea) were conducted. Cry1A.105, Cry1F, Cry3Bb1, and Cry34Ab1 moved in a...

Data from: The relationship between plumage colouration, problem-solving and learning performance in great tits Parus major

Laure Cauchard, Stéphanie M. Doucet, Neeltje J. Boogert, Bernard Angers & Blandine Doligez
Recent studies suggest that individuals with better problem-solving and/or learning performance have greater reproductive success, and that individuals may thus benefit from choosing mates based on these performances. However, directly assessing these performances in candidate mates could be difficult. Instead, the use of indirect cues related to problem-solving and/or learning performance, such as condition-dependent phenotypic traits, might be favored. We investigated whether problem-solving and learning performance on a novel non-foraging task correlated with sexually selected...

Data from: Phylogenetic composition of host plant communities drives plant-herbivore food web structure

1. Insects tend to feed on related hosts. The phylogenetic composition of host plant communities thus plays a prominent role in determining insect specialization, food web structure, and diversity. Previous studies showed a high preference of insect herbivores for congeneric and confamilial hosts suggesting that some levels of host plant relationships may play more prominent role that others. 2. We aim to quantify the effects of host phylogeny on the structure of quantitative plant-herbivore food...
