Sperm competition may select for male reproductive traits that influence female mating or oviposition rate. These traits may induce fitness costs to the female; however, they may be costly for the males as well as any decrease in female fitness also affects male fitness. Male adaptations to sperm competition manipulate females by altering not only female behaviour or physiology, but also female morphology. In orb-weaving spiders, mating may entail mutilation of external structures of the female genitalia, which prevents genital coupling with subsequent males. Here, we present a game theoretical model showing that external female genital mutilation is favoured even under relatively high costs of mutilation, and that it is favoured by a high number of mate encounters per female and last-male sperm precedence.

Evolution of male and female choice in polyandrous systems
Puurtinen, Mikael; Fromhage, Lutz (The Royal Society Publishing, 2017)We study the evolution of male and female mating strategies and mate choice for female fecundity and male fertilization ability in a system where both sexes can mate with multiple partners, and where there is variation in ... -
Sexual dimorphism in subterranean amphipod crustaceans covaries with subterranean habitat type
Premate, Ester; Fišer, Žiga; Biro, Anna; Copilas-Ciocianu, Denis; Fromhage, Lutz; Jennions, Michael; Borko, Špela; Herczeg, Gábor; Balazs, Gergely; Kralj-Fišer, Simona; Fišer, Cene (Oxford University Press, 2024)Sexual dimorphism can evolve in response to sex-specific selection pressures that vary across habitats. We studied sexual differences in subterranean amphipods Niphargus living in shallow subterranean habitats (close to ... -
The evolution of mating preferences for genetic attractiveness and quality in the presence of sensory bias
Henshaw, Jonathan M.; Fromhage, Lutz; Jones, Adam G. (National Academy of Sciences, 2022)The aesthetic preferences of potential mates have driven the evolution of a baffling diversity of elaborate ornaments. Which fitness benefit—if any—choosers gain from expressing such preferences is controversial, however. ... -
Sex roles and the evolution of parental care specialization
Henshaw, Jonathan M.; Fromhage, Lutz; Jones, Adam G. (The Royal Society Publishing, 2019)Males and females are defined by the relative size of their gametes (anisogamy), but secondary sexual dimorphism in fertilization, parental investment and mating competition is widespread and often remarkably stable over ... -
Individual- and group-level sex ratios under local mate competition : consequences of infanticide and reproductive dominance
Lehtonen, Jussi; Malabusini, Serena; Guo, Xiaomeng; Hardy, Ian C. W. (European Society of Evolutionary Biology; Society for the Study of Evolution; Oxford University Press, 2023)Extremely female-biased sex ratios of parasitoid wasps in multiple-foundress groups challenges evolutionary theory which predicts diminishing bias as foundress numbers increase. Recent theory based on foundress cooperation ...
