Strategic adjustment of ejaculate quality in response to variation of the socio-sexual environment
M Magris - Behavioral Ecology and Sociobiology, 2021 - Springer
Strategic ejaculate adjustments occur when males modify their investment in sperm and
nonsperm components of the ejaculate according to the context. This strategy is expected to …

COSTS AND BENEFITS OF LIFETIME EXPOSURE TO MATING RIVALS IN MALE DROSOPHILA MELANOGASTER
Abstract Theory predicts that males should evolve mechanisms to assess competition and
allocate resources accordingly. This requires phenotypic plasticity, to accurately match …

[HTML][HTML] Taste and pheromonal inputs govern the regulation of time investment for mating by sexual experience in male Drosophila melanogaster
SG Lee, D Sun, H Miao, Z Wu, C Kang, B Saad… - PLoS …, 2023 - journals.plos.org
Males have finite resources to spend on reproduction. Thus, males rely on a 'time investment
strategy'to maximize their reproductive success. For example, male Drosophila …

Genomic responses to the socio-sexual environment in male Drosophila melanogaster exposed to conspecific rivals
Socio-sexual environments have profound effects on fitness. Local sex ratios can alter the
threat of sexual competition, to which males respond via plasticity in reproductive behaviors …

[HTML][HTML] Male control of mating duration following exposure to rivals in fruitflies
Males of many species assess the likely level of sperm competition and respond adaptively,
for example by increasing the level of courtship they deliver, by transferring more sperm or …

Exposure time to rivals and sensory cues affect how quickly males respond to changes in sperm competition threat
Phenotypic plasticity can increase fitness in rapidly changeable environments, but may be
limited if the underlying mechanisms cause a lag between environmental change and …

Rival male chemical cues evoke changes in male pre-and post-copulatory investment in a flour beetle
Males can gather information on the risk and intensity of sperm competition from their social
environment. Recent studies have implicated chemosensory cues, for instance cuticular …

Playing to the crowd: Using Drosophila to dissect mechanisms underlying plastic male strategies in sperm competition games
Post-copulatory sexual selection, the post-mating competition between ejaculates, is now
widely established as a potent evolutionary driver. However, the competitive environment …
