“…; Takeshita et al. ), some studies have found that larger males impose longer mate‐guarding durations, but only when females were able to resist male guarding attempts (Jormalainen & Merilaita , ). These studies suggest that larger males are often better at overcoming female resistance to pairing than small males.…”

“…In stone leek leafminers (Liriomyza chinensis), there was no effect of male body size on the harm imposed on females (Tran & Takagi 2006). In crustaceans, where males and females often disagree over precopulatory mate-guarding duration (e.g., Jormalainen & Shuster 1999;Sparkes et al 2000;Takeshita et al 2011), some studies have found that larger males impose longer mate-guarding durations, but only when females were able to resist male guarding attempts (Jormalainen & Merilaita 1993, 1995. These studies suggest that larger males are often better at overcoming female resistance to pairing than small males.…”

An assessment of Putative Sexually Antagonistic Traits in a Freshwater Amphipod Species

2015

Sexual conflict can result in an 'evolutionary arms race' between males and females, with the evolution of sexual antagonistic traits used to resolve the conflict in favor of one sex over the other. We assessed the resolution of sexual conflict in a Hyalella amphipod species by manipulating putative sexually antagonistic traits in males and females and used mateguarding duration as our metric of conflict resolution. We discovered that large male posterior gnathopod size increased mate-guarding duration, which suggests that it is a sexually antagonistic trait in this species. In contrast, female and male body size did not significantly affect mate-guarding duration. Given that male posterior gnathopods show heightened condition dependence, future investigations should explore the interactive effects of sexual conflict and ecological context on trait evolution, phenotypic divergence, and speciation to elucidate the complex mechanisms involved in the evolution of biological diversity.

“…This difference in optimal mating rate affects the level of sexual conflict (Arnqvist and Rowe, 2005). Generally, male mating strategies impose non-trivial reproductive costs on females in terms of offspring production (Rossi, Nonacs, and Pitts-Singer, 2010; Takeshita, Lombardo, Wada, and Henmi, 2011), male harassment (Helinski and Harrington, 2012), insemination (Arnqvist and Nilsson, 2000), maternal care (Boncoraglio and Kilner, 2012), physical injury (Crudgington and Siva-Jothy, 2000) and/or death (Leboeuf and Mesnick, 1991; Réale, Boussès, and Chapuis, 1996). Sexual selection is expected to favor counter-adaptations to these costs in females that will maximize their individual fitness (Arnqvist and Rowe, 2005).…”

Rape Avoidance Behavior among Slovak Women

Rape has been a recurrent adaptive problem for many species, including humans. Rape is costly to women in terms of disease transmission, partner abandonment, and unwanted pregnancy (among other costs). Therefore, behavioral strategies which allow women to avoid coercive men may have been favored by selection. In line with this evolutionary reasoning, the current research documented that physically stronger women and those in a committed romantic relationship reported more rape avoidance behavior. In addition, virgin women tended to perform more rape avoidance behavior compared with their non-virgin counterparts. Women with high conception risk perceived themselves as physically stronger, which may protect them against a potential rapist. Fear of unwanted pregnancy from rape decreased as age increased, reflecting higher fertility among younger participants. However, older women reported more rape avoidance behavior, which contradicts evolutionary predictions. The results provide some support for evolutionary hypotheses of rape avoidance behavior which suggest that woman's perception of rape is influenced by parental investment and perceived physical condition.
