Data from: Evidence for a recent horizontal transmission and spatial spread of Wolbachia from endemic Rhagoletis cerasi (Diptera: Tephritidae) to invasive Rhagoletis cingulata in Europe

The widespread occurrence of Wolbachia in arthropods and nematodes suggests that this intracellular, maternally inherited endosymbiont has the ability to cross species boundaries. However, direct evidence for such a horizontal transmission of Wolbachia in nature is scarce. Here, we compare the well-characterized Wolbachia infection of the European cherry fruit fly, Rhagoletis cerasi, with that of the North American eastern cherry fruit fly, Rhagoletis cingulata, recently introduced to Europe. Molecular genetic analysis of Wolbachia based on...

Data from: How generalist herbivores exploit belowground plant diversity in temperate grasslands

Belowground herbivores impact plant performance, thereby inducing changes in plant community composition, which potentially leads to cascading effects onto higher trophic levels and ecosystem processes and productivity. Amongst soil-living insects, external root-chewing generalist herbivores have the strongest impact on plants. However, the lack of knowledge on their feeding behaviour under field conditions considerably hampers achieving a comprehensive understanding of how they affect plant communities. Here, we address this gap of knowledge by investigating the feeding...

Data from: Strong nuclear differentiation contrasts with widespread sharing of plastid DNA haplotypes across taxa in European purple saxifrages (Saxifraga sect. Porphyrion subsect. Oppositifoliae)

Manuela Winkler, Andreas Tribsch, Gerald M. Schneeweiss, Sabine Brodbeck, Felix Gugerli, Rolf Holderegger & Peter Schönswetter
The purple saxifrages, Saxifraga sect. Porphyrion subsect. Oppositifoliae, comprise the closest relatives of the arctic-alpine model plant S. oppositifolia and have a centre of diversity in the central and southern European mountain ranges. A multitude of taxa has been described and taxonomic concepts vary among different treatments. Using amplified fragment length polymorphism (AFLP) fingerprinting we show that some taxa indeed form strongly supported genetic entities best recognized on the species level (S. biflora, S. blepharophylla,...

Data from: Sex allocation adjustment to mating group size in a simultaneous hermaphrodite

Tim Janicke, Lucas Marie-Orleach, Katrien De Mulder, Eugene Berezikov, Peter Ladurner, Dita Brigida Vizoso & Lukas Schärer
Sex allocation theory is considered as a touchstone of evolutionary biology, providing some of the best supported examples for Darwinian adaptation. In particular, Hamilton’s local mate competition theory has been shown to generate precise predictions for extraordinary sex ratios observed in many separate-sexed organisms. In analogy to local mate competition, Charnov’s mating group size model predicts how sex allocation in simultaneous hermaphrodites is affected by the mating group size (i.e., the number of mating partners...

Data from: How diverse is Mitopus morio? Integrative taxonomy detects cryptic species in a small-scale sample of a widespread harvestman

Wolfgang Arthofer, Hannes Rauch, Barbara Thaler-Knoflach, Karl Moder, Christoph Muster, Birgit C. Schlick-Steiner & Florian M. Steiner
Mitopus morio is a widespread harvestman species occurring in most of Europe and in moderate and cold-moderate zones of Asia and North America. The species is characterized by extreme variability in body size and leg length. As leg length is correlated with habitat temperature, M. morio has been considered as an example of Allen's rule. Recently, observations for a single location in Tyrol, Austria, indicated the absence of mating between short- and long-legged individuals. This...
