Monogynous males in various species actively limit themselves to mating with a single female in their lifetime. Whereas previous models have considered monogyny as an obligate mating strategy, here we explore the potential of monogyny to evolve as a context-specific (conditional) behavior. Using a state-dependent dynamic game model based on the biology of the cannibalistic spider Argiope bruennichi, we confirm that conditional monogyny can evolve under broad conditions, including an even sex ratio. We predict that males should make a terminal investment when mating with large, virgin females, especially if population density is low and the encounter occurs late in the season. We encourage empirical tests for the existence of conditional monogyny in all species where monogyny occurs in the absence of strict morphological constraints that would make it obligatory.

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 ... -
The Bruce effect revisited : is pregnancy termination in female rodents an adaptation to ensure breeding success after male turnover in low densities?
Eccard, Jana; Dammhahn, Melanie; Ylönen, Hannu (Springer, 2017)Pregnancy termination after encountering a strange male, the Bruce effect, is regarded as a counterstrategy of female mammals towards anticipated infanticide. While confirmed in caged rodent pairs, no verification for the ... -
Female Sexual Signaling in a Capital Breeder, the European Glow-Worm Lampyris noctiluca
Baudry, Gautier; Hopkins, Juhani; Watts, Phillip C.; Kaitala, Arja (Springer, 2021)Theory predicts that because costs constrain female sexual signaling, females are expected to have a low signaling effort that is increased with passing time until mating is secured. This pattern of signaling is expected ... -
Fluctuating asymmetry and sexual performance in the drumming wolf spider Hygrolycosa rubrofasciata
Ahtiainen, Jari J.; Alatalo, Rauno Veli; Mappes, Johanna; Vertainen, Laura (Finnish Zoological and Botanical Publishing Board, 2003)Recently, there has been much interest in estimating fluctuating asymmetry (FA) of morphological traits as a short-cut measure of individual quality. FA deals with small differences around the symmetry value of zero. Thus, ... -
Condition-dependence of male sexual signalling in the drumming wolf spider Hygrolycosa rubrofasciata
Ahtiainen, Jari J. (Jyväskylän yliopisto, 2003)Jari Ahtiaisen väitöskirjatyön tutkimusten perusteella voidaan todeta, että H. rubrofasciata susihämähäkkinaaraat voivat käyttää koiraan seksuaalista kuntoa mittana arvioidessaan koiraan fenotyyppistä ja geneettistä laatua. ...
