TLDR
It is suggested that age-based preference by females can be consistent across populations with very different environments, even when those populations differ in other key mating-related traits such as offspring production and copulation duration.About:

The impact of ageing on male reproductive success in Drosophila melanogaster
TL;DR: It is suggested that ejaculates of older males are less effective at inducing beneficial responses and that older male flies produce smaller or ill‐composed ejaculates, significantly affecting his reproductive success.

TL;DR: This review summarizes the current knowledge of drive resistance in both natural and synthetic gene drives and explores how insights from naturally occurring and synthetic drive systems can be integrated to improve the design of gene drives, better predict the outcome of releases and understand genomic conflict in general.
Journal ArticleDOI
Designing mate choice experiments
TL;DR: There is no single ‘correct’ approach to measuring choice across species, although ecological relevance is crucial if the aim is to understand how choice acts in natural populations, and the need for quantitative estimates of the sizes of potentially important effects is highlighted.

Gene expression changes in male accessory glands during ageing are accompanied by reproductive decline in Drosophila melanogaster.
Mareike Koppik,Claudia Fricke +1 more
TL;DR: Male reproductive senescence is associated with a decline in functionality of the male accessory gland and the composition of an ejaculate might change with male age as the rate of change was variable for those five genes.
Journal ArticleDOI
Differing effects of age and starvation on reproductive performance in Drosophila melanogaster.
TL;DR: The results indicate that the immediate costs of mating differ between males and females, and that the sexes differ in their perception of the opportunity cost sustained by refusing a mating opportunity, and support the idea that ageing has more wide-ranging impact on reproductive behaviours than does nutritional challenge.

What Use is an Infertile Sperm? A Comparative Study of Sperm-Heteromorphic Drosophila
TL;DR: It was found that parasperm size was unrelated to female reproductive tract morphology but was negatively related to the two indices of sperm competition, suggesting that postcopulatory sexual selection may indeed have shaped the evolution of parasperm.
Journal ArticleDOI
When are vomiting males attractive? Sexual selection on condition-dependent nuptial feeding in Drosophila subobscura
TL;DR: The findings suggest that, in this monandrous species, selection has favored males who invest innuptial gifts, possibly as an example of paternal investment as well as mating effort, but that the strength of selection on nuptial feeding is strongly subject to environmental variation.

Female preference for the songs of older males and the maintenance of dialects in brown-headed cowbirds (Molothrus ater)
TL;DR: Female brown-headed cowbirds in the Sierra Nevada of California discriminate between yearling and adult male vocalizations based on two vocal characteristics that often distinguish songs of these age classes, incomplete renditions of the local dialect flight whistle and 'unique', unshared perched song types.

Perception of male–male competition influences Drosophila copulation behaviour even in species where females rarely remate
TL;DR: It is tested the prediction that males do not adjust their copulation effort in response to the presence of a competitor in Drosophila species where there is little or no sperm competition, and contrary to expectations, male plasticity in copulation duration was found in both Dosophila subobscura and Drosophile acanthoptera.

Female mate choice based on territory quality in barn swallows
TL;DR: It is inferred that female swallows choose their mates based, in part, on territory quality, because males with better territories paired with females earlier, and hence bred earlier, than those with inferior territories.
