Data from: Sexual harassment induces a temporary fitness cost but does not constrain the acquisition of environmental information in fruit flies
Across animals, sexual harassment induces fitness costs for females and males. However, little is known about the cognitive costs involved, i.e. whether it constrains learning processes, which could ultimately affect an individual's fitness. Here we evaluate the acquisition of environmental information in groups of fruit flies challenged with various levels of male sexual harassment. We show that, although high sexual harassment induces a temporary fitness cost for females, all fly groups of both sexes exhibit similar levels of learning. This suggests that, in fruit flies, the fitness benefits of acquiring environmental information are not affected by the fitness costs of sexual harassment, and that selection may favour cognition even in unfavourable social contexts. Our study provides novel insights into the relationship between sexual conflicts and cognition and the evolution of female counterstrategies against male sexual harassment.
Data from: Exposure to males, but not receipt of sex peptide, accelerates functional aging in female fruit flies
Increased exposure to males can affect females negatively, reducing female lifespan and fitness. These costs could derive from increased mating rate and also harassment by males. Additionally, early investment in reproduction can increase the onset or rate of senescence in reproductive traits. Hence, there is a tight link between reproduction and aging. Here, we assess how mating and encounter rate with males impacts declines in female functional traits that are not directly involved in reproduction. In Drosophila melanogaster fruit flies, exposure to males and mating reduces female lifespan through harassment and receipt of seminal proteins, including sex peptide. We manipulated the intensity of female exposure to males and regularly assessed female stress responses and recorded physiological traits over her lifetime. Both mating itself and increased exposure to males accelerates declines in female climbing ability and starvation resistance. However, this is not related to changes in female body mass or fat storage. Moreover, these declines are not driven by the receipt of sex peptide. Our results suggest some synchrony in senescence across traits in response to female exposure to males, however this is not universal, as we did not find this for physiological traits. Synchrony in senescence has been theorised but little supported in the literature. It is clear that aging is a multifaceted trait; to understand environmental impacts on aging rates we must measure more than lifespan, and indeed measure senescence in multiple traits. Specifically, our work shows that we must identify which female traits are sensitive to elevated mating activity to understand the impact of antagonistic interactions between the sexes on female aging patterns.
Data from: Fruit flies diversify their offspring in response to parasite infection
The evolution of sexual reproduction is often explained by Red Queen dynamics: Organisms must continually evolve to maintain fitness relative to interacting organisms, such as parasites. Recombination accompanies sexual reproduction and helps diversify an organism's offspring, so that parasites cannot exploit static host genotypes. Here we show that Drosophila melanogaster plastically increases the production of recombinant offspring after infection. The response is consistent across genetic backgrounds, developmental stages, and parasite types but is not induced after sterile wounding. Furthermore, the response appears to be driven by transmission distortion rather than increased recombination. Our study extends the Red Queen model to include the increased production of recombinant offspring and uncovers a remarkable ability of hosts to actively distort their recombination fraction in rapid response to environmental cues.

Figs. 1–7 in Biology And Description Of The Third Instar Larva And Puparium Of Ichneumonopsis Burmensis Hardy (Diptera: Tephritidae: Dacinae: Gastrozonini), A Bamboo-Breeding Fruit Fly From The Oriental Region
Figs. 1–7. Adults, habitat and development of I. burmensis-larvae. 1, Habitus of I. burmensis female. 2, Bamboo stand of M. compactiflorus in north Thailand at the edge of a field in November. The bamboo shoot in the front was damaged by a larva of the weevil Cyrtotrachelus sp. and the apical part of the main stem has dropped to the ground (large arrow points to the stump of the main stem). One of the resulting side branches of the main stem is infested by an I. burmensis larva (ii). The large side branch on the left has taken over the function of the main stem. 3, Cross-section through an M. compactiflorus internode near the apex of the bamboo shoot (diameter: 7 mm). The internode cavity contains white pith. 4, Apical part of an infested bamboo shoot of M. compactiflorus. The arrow points to the internode containing an I. burmensis larva. The upper internodes are dead but still attached to the bamboo shoot. 5, I. burmensis larva feeding on the white pith inside a bamboo internode (diameter of the internode cavity: 3–4 mm). 6, Bamboo fibres, ca. 5–7 cm long, recently torn off by the larva. 7, Lateral cut through an I. burmensis-internode (base of the internode on the left). The larva has eaten up about half of the white pith in the basal part the internode cavity and has freshly pupated at the base of the internode. Note the thin bamboo wall at the level of the exit hole. Most of the torn off vascular fibres have been removed in order to show the puparium. They filled the cavity beween the puparium and the "vf" arrow. eh = exit hole; bp = bamboo pith; bb = branch bud; ii = I. burmensis-internode; p = puparium; vf = vascular fibres.
