Most research on sexual cannibalism has focused on factors influencing female motivation to engage in cannibalism. However, a critical factor that may mediate the actual occurrence of sexual cannibalism is male vulnerability to female attacks. We tested whether sexual size dimorphism (SSD) affected whether hungry females were successful in sexual cannibalism in a moderately size dimorphic wolf spider, Hogna helluo. Experimentally food-limited females cannibalized males more frequently than did… Expand
Male vulnerability explains the occurrence of sexual cannibalism in a moderately sexually dimorphic wolf spider
TLDR
In a moderately sexually dimorphic wolf spider, sexual cannibalism is interpreted as a strategic foraging decision for H. radiata females that adjust their aggressive behaviour towards males so as to limit its potential costs. Expand
Male sexual cannibalism in a sand-dwelling wolf spider with sex role reversal
TLDR
This is the first report of male sexual cannibalism in a sex role reversed system and the astonishing male cannibalistic behaviour best agrees with extreme mate choice hypotheses because attacks were more frequent on mated females of low body condition. Expand
Mate quality, not aggressive spillover, explains sexual cannibalism in a size-dimorphic spider
TLDR
In support of the mate choice hypothesis, less aggressive males were more likely attacked and cannibalized than more aggressive ones, which hints at sexual selection for aggressiveness in males and raises the question of mechanisms that maintain variation in male aggressiveness. Expand
Sexual cannibalism is associated with female behavioural type, hunger state and increased hatching success
TLDR
It was found that more aggressive females and those deprived of food were more likely to engage in precopulatory cannibalism and offspring of cannibalistic mothers appear to have increased hatching success in heavier egg cases, which may represent a novel advantage associated with sexual cannibalism.

Body Size, Not Personality, Explains Both Male Mating Success and Sexual Cannibalism in a Widow Spider
TLDR
It is shown that individual variation in aggression levels plays no direct role in the mating behavior of the Mediterranean black widow, and body size affects male mating success and occurrences of sexual cannibalism in females. Expand
Factors influencing sexual cannibalism and its benefit to fecundity and offspring survival in the wolf spider Pardosa pseudoannulata (Araneae: Lycosidae)
TLDR
The hypothesis that sexual cannibalism has evolved as an adaptive component of female foraging strategy and that it benefits offspring survival as a result of paternal investment is supported. Expand
Feeding regime, adult age and sexual size dimorphism as determinants of pre-copulatory sexual cannibalism in virgin wolf spiders
TLDR
Pre-copulatory cannibalism in virgin females was predicted by their food availability during adulthood, age at first male encounter and the relative body size of the courting male. Expand
Sexual cannibalism in the European garden spider Araneus diadematus: the roles of female hunger and mate size dimorphism
TLDR
The results suggest that a complex interplay of female state, mate choice and physical dominance is responsible for the maintenance of sexual cannibalism against male interests. Expand
Does personality explain variation in the probability of sexual cannibalism in the orb-web spider Argiope aurantia?
TLDR
It is found that aggressive foragers are more likely to attack their mates, but it is concluded that other, possibly adaptive reasons for cannibalism exist as much of the uncertainty in cannibalism occurrence remained unexplained. Expand
The Importance of Ecological and Phylogenetic Conditions for the Occurrence and Frequency of Sexual Cannibalism
TLDR
This review examines how ecological and phylogenetic factors may affect the occurrence and frequency of sexual cannibalism within and among species. Expand

The Role of Body Size in Mating Interactions of the Sexually Cannibalistic Fishing Spider Dolomedes triton
TLDR
Results suggest that male size does not influence courtship behavior, the likelihood of being attacked, or the male's ability to secure a mounting, but large males were superior at gaining copulations once mounted, suggesting benefits of large male body size. Expand
Sexual Size Dimorphism Predicts the Frequency of Sexual Cannibalism Within and Among Species of Spiders
TLDR
There is the first evidence that the degree of size difference between males and females is related to the phylogenetic distribution of sexual cannibalism among a broad range of spiders. Expand

Mating strategies are to a large degree shaped by conflicts between the sexes, causing a rapid antagonistic coevolution of traits involved in reproduction. The view that sexual cannibalism representsExpand
Evolutionary Significance of Sexual Cannibalism
TLDR
This chapter discusses sexual cannibalism in the context of both sexual and natural selection, highlighting how the timing ofSexual cannibalism changes the costs and benefits to males and females. Expand
Cohabitation of juvenile females with mature males promotes sexual cannibalism in fishing spiders
TLDR
This is the first study to suggest that juvenile experience can alter a female's propensity for sexual cannibalism, and emphasizes the point that studies of sexual selection and mating systems need to consider the effects of juvenile experience on adult behavior. Expand

TLDR
Results suggest that both mate choice and sexual cannibalism can impose reinforcing directional selection on male size and secondary sexual characters. Expand
Sexual cannibalism in the fishing spider and a model for the evolution of sexual cannibalism based on genetic constraints
TLDR
It is proposed that the act of sexual cannibalism in the fishing spider is non-adaptive, and a model for the evolution of premating sexual cannibalisms in spiders based on genetic constraints is developed. Expand
Age Affects the Risk of Sexual Cannibalism in Male Crab Spiders (Misumena vatia)
TLDR
Female crab spiders Misumena vatia (Thomisidae) regularly attacked prospective mates experimentally presented in pairs whose individuals differed in age, paralleled a decline in numbers of field-observed males, probably a consequence of their increasing vulnerability to sexual cannibalism. Expand
Fitness consequences of sexual cannibalism in female Argiope bruennichi
TLDR
It is concluded that the paternal investment hypothesis does not explain the existence of sexual cannibalism in A. bruennichi and probably not in other spider species with a pronounced sexual size dimorphism. Expand

TLDR
It is argued that the relationship between sexual size dimorphism and relative male leg length within the Araneinae may be the result of selection imposed by sexual cannibalism by females. Expand
