Age-based mate choice in the monandrous fruit fly Drosophila subobscura

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.

Conflict between direct and indirect benefits of female choice in desert Drosophila
TL;DR: The results are intriguing and are consistent with the hypothesis that an interaction between direct and indirect benefits maintains sexually antagonistic variation in these desert flies: increased desiccation resistance conferred by mating might offset the cost of producing low-fecundity daughters.

The genetics of Drosophila subobscura populations XVIII. Multiple insemination and sperm displacement in Drosophila subobscura
TL;DR: The multiple insemination of Drosophila subobscura females in nature was studied by the analysis of single female offspring using two highly polymorphic enzyme systems and it was found that 23% of these females were inseminated at least twice.
Journal ArticleDOI
Male courtship behavior and weapon trait as indicators of indirect benefit in the bean bug, Riptortus pedestris.
TL;DR: It is evident that courtship rate and hind leg length act as evaluative cues of female choice and male–male competition may facilitate each other in R. pedestris, consistent with current basic concepts of sexual selection.

No evidence of mate discrimination against males carrying a sex ratio distorter in Drosophila pseudoobscura

TL;DR: It is suggested that the lack of female choice against SGE-carrying males may be due to strong selection on SGEs to be indistinguishable from alternative alleles, and polyandry, either in direct response to receiving an ejaculate from an SGE -carrying male or carried out indiscriminately when at risk of mating with carriers, may be an alternative response by females to limit the exposure of their offspring to S GEs.

Extreme cost of rivalry in a monandrous species: male-male interactions result in failure to acquire mates and reduced longevity.
TL;DR: It is concluded that males in monandrous species suffer severe physiological costs from interactions with rivals and note the significance of male–male interactions as a source of stress in laboratory culture.
