Data from: Feeding-induced rearrangement of green leaf volatiles reduces moth oviposition

Silke Allmann, Anna Späthe, Sonja Bisch-Knaden, Mario Kallenbach, Andreas Reinecke, Silke Sachse, Ian T. Baldwin & Bill S. Hansson
The ability to decrypt volatile plant signals is essential if herbivorous insects are to optimize their choice of host plants for their offspring. Green leaf volatiles (GLVs) constitute a widespread group of defensive plant volatiles that convey a herbivory-specific message via their isomeric composition: feeding of the tobacco hornworm Manduca sexta converts (Z)-3- to (E)-2-GLVs thereby attracting predatory insects. Here we show that this isomer-coded message is monitored by ovipositing M. sexta females. We detected...

Data from: Flexible weighing of olfactory and vector information in the desert ant Cataglyphis fortis

Cornelia Buehlmann, Bill S. Hansson & Markus Knaden
Desert ants, Cataglyphis fortis, are equipped with remarkable skills that enable them to navigate efficiently. When travelling between the nest and a previously visited feeding site, they perform path integration (PI), but pinpoint the nest or feeder by following odour plumes. Homing ants respond to nest plumes only when the path integrator indicates that they are near home. This is crucial, as homing ants often pass through plumes emanating from foreign nests and do not...

Data from: Mechanisms of macroevolution: polyphagous plasticity in butterfly larvae revealed by RNA-Seq

Maria De La Paz Celorio-Mancera, Christopher W. Wheat, Heiko Vogel, Lina Söderlind, Niklas Janz & Sören Nylin
Transcriptome studies of insect herbivory are still rare, yet studies in model systems have uncovered patterns of transcript regulation that appear to provide insights into how insect herbivores attain polyphagy, such as a general increase in expression breadth and regulation of ribosomal, digestion- and detoxification-related genes. We investigated the potential generality of these emerging patterns, in the Swedish comma, Polygonia c-album, which is a polyphagous, widely-distributed butterfly. Urtica dioica and Ribes uva-crispa are hosts of...

Data from: Pollinator shifts between Ophrys sphegodes populations: might adaptation to different pollinators drive population divergence?

Hendrik Breitkopf, Philipp M. Schlüter, Shuqing Xu, Florian P. Schiestl, Salvatore Cozzolino & Giovanni Scopece
Local adaptation to different pollinators is considered one of the possible initial stages of ecological speciation as reproductive isolation is a by-product of the divergence in pollination systems. However, pollinator-mediated divergent selection will not necessarily result in complete reproductive isolation, because incipient speciation is often overcome by gene flow. We investigated the potential of pollinator shift in the sexually deceptive orchids Ophrys sphegodes and Ophrys exaltata and compared the levels of floral isolation vs. genetic...

Data from: The role of glucosinolates and the jasmonic acid pathway in resistance of Arabidopsis thaliana against molluskan herbivores

Although slugs and snails play important roles in terrestrial ecosystems and cause considerable damage on a variety of crop plants, knowledge about the mechanisms of plant immunity to mollusks is limited. We found slugs to be natural herbivores of Arabidopsis thaliana and therefore investigated possible resistance mechanisms of this species against several molluskan herbivores. Treating wounded leaves with the mucus residue (“slime trail”) of the Spanish slug Arion lusitanicus increased wound-induced jasmonate levels, suggesting the...

Data from: Microsatellites for the marsh Fritillary butterfly: de novo transcriptome sequencing, and a comparison with amplified fragment length polymorphism (AFLP) markers

BACKGROUND: Until recently the isolation of microsatellite markers from Lepidoptera has proved troublesome, expensive and time-consuming. Following on from a previous study of Edith's checkerspot butterfly, Euphydryas editha, we developed novel microsatellite markers for the vulnerable marsh fritillary butterfly, E. aurinia. Our goal was to optimize the process in order to reduce both time and cost relative to prevailing techniques. This was accomplished by using a combination of previously developed techniques: in silico mining of...

Data from: Trade-offs between personal immunity and reproduction in the burying beetle, N. vespilloides

Catherine E. Reavey, Neil D. Warnock, Heiko Vogel & Sheena C. Cotter
We know that parental investment and immune investment are costly processes, but it is unclear which trait will be prioritized when both may be required. Here, we address this question using the burying beetle Nicrophorus vespilloides, carrion breeders that exhibit biparental care of young. Our results show that immunosuppression occurs during provision of parental care. We measured phenoloxidase (PO) on Days 1–8 of the breeding bout and results show a clear decrease in PO immediately...

Data from: Asexual genome evolution in the apomictic Ranunculus auricomus complex: examining the effects of hybridization and mutation accumulation

Marco Pellino, Diego Hojsgaard, Thomas Schmutzer, Uwe Scholz, Elvira Hörandl, Heiko Vogel & Timothy F. Sharbel
Asexual lineages are thought to be prone to extinction because of deleterious mutation accumulation (Muller's ratchet). Here we analyze genomic effects of hybridity, polyploidy and allelic divergence in apomictic plants, and identify loci under divergent selection among sexual/apomictic lineages. RNAseq was used to sequence the flower-specific transcriptomes of 5 genotypes of the Ranunculus auricomus complex, representing 3 sexual and 2 apomictic reproductive biotypes. The 5 sequence libraries were pooled and de novo assembly performed, and...

Data from: Unearthing carrion beetles’ microbiome: characterization of bacterial and fungal hindgut communities across the Silphidae

Martin Kaltenpoth & Sandra Steiger
Carrion beetles (Coleoptera, Silphidae) are well known for their behaviour of exploiting vertebrate carcasses for nutrition. While species in the subfamily Silphinae feed on large carcasses and on larvae of competing scavengers, the Nicrophorinae are unique in monopolizing, burying and defending small carrion, and providing extensive biparental care. As a first step towards investigating whether microbial symbionts may aid in carcass utilization or defence, we characterized the microbial hindgut communities of six Nicrophorinae (Nicrophorus spp.)...
