Data from: Sexual selection on song and cuticular hydrocarbons in two distinct populations of Drosophila montana

Paris Veltsos, Claude Wicker-Thomas, Roger K. Butlin, Anneli Hoikkala & Michael G. Ritchie
Sexual selection has the potential to contribute to population divergence and speciation. Most studies of sexual selection in Drosophila have concentrated on a single signaling modality, usually either courtship song or cuticular hydrocarbons (CHCs), which can act as contact pheromones. We have examined the relationship between both signal types and reproductive success using F1-3 offspring of wild-collected flies, raised in the lab. We used two populations of the Holarctic species Drosophila montana, that represent different...

Data from: Sexual selection on male development time in the parasitoid wasp Nasonia vitripennis

Anna M Moynihan & Dave M Shuker
Mating systems are shaped by a species’ ecology, which sets the stage for sexual selection. Males of the gregarious parasitoid wasp Nasonia vitripennis compete to mate virgin females at the natal site, before females disperse. Males could increase their fitness by being larger and monopolising female emergence sites, or by emerging earlier pre-empting access to females. We consider sexual selection on male body size and development tine in Nasonia, and a potential trade-off between the...

Data from: Multiple quantitative trait loci influence intra-specific variation in genital morphology between phylogenetically distinct lines of Drosophila montana

Martin A Schäfer, Jarkko Routtu, Jorge Vieira, Anneli Hoikkala, Mike G Ritchie & Christian Schlötterer
The evolution of animal genitalia has gained renewed interest, because of their potential roles during sexual selection and early stages of species formation. Although central to understanding the evolutionary process, knowledge of the genetic basis of natural variation in genital morphology is limited to a very few species. Using an out-bred cross between phylogenetically distinct lines of Drosophila montana, we characterized quantitative trait loci (QTLs) affecting the size and shape of the distiphallus, a prominent...

Data from: Genetic divergence, range expansion and possible homoploid hybrid speciation among pine species in northeast China

Guangpeng Ren, Richard J. Abbott, Yongfeng Zhou, Lirui Zhang, Yanling Peng, G-P Ren, Y-F Zhou, L-R Zhang, Y-L Peng & J-Q Liu
Although homoploid hybrid speciation in plants is probably more common than previously realized, there are few well-documented cases of homoploid hybrid origin in conifers. We examined genetic divergence between two currently widespread pines in northeast China, Pinus sylvestris var. mongolica and P. densiflora, and also whether two narrowly distributed pines in the same region, P. funebris and P. takahasii, might have originated from the two widespread species by homoploid hybrid speciation. Our results, based on...

Data from: No evidence for host specialization or host-race formation in the European bitterling (Rhodeus amarus), a fish that parasitizes freshwater mussels

Martin Reichard, Josef Bryja, Matej Polačik & Carl Smith
Coevolutionary relationships between parasites and hosts can elevate the rate of evolutionary changes due to reciprocal adaptations between coevolving partners. Such relationships can result in the evolution of host specificity. Recent methodological advances have permitted the recognition of cryptic lineages, with important consequences for our understanding of biological diversity. We used the European bitterling (Rhodeus amarus), a freshwater fish that parasitizes unionid mussels, to investigate host specialization across regions of recent and ancient sympatry between...

Data from: Two distinct genomic regions, harbouring the period and fruitless genes, affect male courtship song in Drosophila montana

Malgorzata Lagisz, Shuo-Yang Wen, Jarkko Routtu, Kirsten Klappert, Dominique Mazzi, Ramiro Morales-Hojas, Jorge Vieira, Anneli Hoikkala, Michael G. Ritchie, Roger K. Butlin, Martin A Schäfer & S-Y Wen
Acoustic signals often play a significant role in pair formation and in species recognition. Determining the genetic basis of signal divergence will help to understand signal evolution by sexual selection and its role in the speciation process. An earlier study investigated QTL for male courtship song carrier frequency in Drosophila montana using microsatellite markers. We refined this study by adding to the linkage map markers for ten candidate genes known to affect song production in...
