Female‐biased size dimorphism, in which females are larger than males, is prevalent in many animals. Several hypotheses have been developed to explain this pattern of dimorphism. One of these hypotheses, the mobility hypothesis, suggests that female‐biased size dimorphism arises because smaller males are favored in scramble competition for mates. Using radiotelemetry, we assessed the mobility hypothesis in the Cook Strait giant weta (Deinacrida rugosa), a species with strong female‐biased size… 

Sexual selection on size and shape in Japanese beetles (Popillia japonica)

Multivariate selection analyses support the prediction that smaller body size and larger wings in males benefit their mating success and partially explain the evolution of female-biased size dimorphism in this species.

The genetic mating system of a sea spider with male-biased sexual size dimorphism: evidence for paternity skew despite random mating success

The suitability of pycnogonids as model systems for addressing questions relating parental investment and sexual selection are highlighted, as well as the current lack of basic information on their natural history and breeding ecology.

Extrapair mating and the strength of sexual selection: insights from a polymorphic species.

The results support previous research suggesting that extrapair mating may play a limited role in driving the overall potential for sexual selection, and increases Bateman gradients and the potential forSexual selection via mate numbers.

Sexual selection, phenotypic variation, and allometry in genitalic and non-genitalic traits in the sexually size-dimorphic stick insect Micrarchus hystriculeus

A negative allometric scaling pattern and low phenotypic variation of clasper size is suggestive of stabilizing selection and supports the ‘one-size-fits-all’ hypothesis.

Multi-modal locomotor costs favor smaller males in a sexually dimorphic leaf-mimicking insect

Large body size impairs flight performance in male leaf insects, providing support to the hypothesis that smaller scrambling males benefit from an increased locomotor performance and shed light on the evolution of sexual dimorphism in scramble competition mating systems.

A novel method of comparing mating success and survival reveals similar sexual and viability selection for mobility traits in female tree crickets

ThisCompared sexual and viability selection on female tree crickets Oecanthus nigricornis, a species where females mate frequently to obtain nuptial gifts and sexual selection on females is likely, found sexual selection for females with larger hind legs and narrower heads and stabilizing viability selection for intermediate head width and hind leg size.

Multi-modal locomotor costs explain sexual size but not shape dimorphism in a leaf-mimicking insect

It is shown that large body size impairs both flight and landing (attachment) performance in male leaf insects (Phyllium philippinicum), a species where relatively small and skinny males fly through the canopy in search of large sedentary females, suggesting that flight costs do not explain the evolution of strong sexual dimorphism in body shape in this species.

Seasonal variation in body size and male mating success within lichen tuft moths Izatha (Lepidoptera: Xyloryctidae)

Animals with scramble competition mating systems commonly exhibit female‐biased sexual size dimorphism, protandry and biased population sex ratios that reflect the active mate‐searching role of

Male-biased sex ratios and plasticity in post-insemination behaviour in the New Zealand stick insect Micrarchus hystriculeus

Although mate guarding duration is similar under male- and female- biased sex ratios, males clasped the genitalia of their mates significantly more often under a male-biased sex ratio, suggesting that males intensify their guarding with increasing risk of sperm competition.



Long‐term paternity skew and the opportunity for selection in a mammal with reversed sexual size dimorphism

Examination of parentage data in a colony of greater horseshoe bats shows that paternity skew and the opportunity for sexual selection in a species with reversed sexual size dimorphism can approach levels reported for classical examples of species with polygyny and male‐biased Dimorphism, even where the traits under sexual selection are not known.

Mortality costs of sexual dimorphism in birds

In this analysis of mortality patterns across 28 North American passerine bird species, it is shown that sex-biased mortality is positively correlated with both sexual size dimorphism and male plumage brightness, and it is argued that the evolution of male brightness has been constrained by mortality costs.

Sexual dimorphism and distorted sex ratios in spiders

This work presents a new model in which high mortality of searching mature males reduces the adult sex ratio (males: females), relaxing male–male competition and reducing the importance of male body size to favour dwarfing by early maturation provides a mechanism that buffers skews inAdult sex ratio.

Allometry for Sexual Size Dimorphism: Pattern and Process in the Coevolution of Body Size in Males and Females

Sexual size dimorphism (SSD) is common in both plants and animals, and current evidence suggests that it reflects the adaptation of males and females to their different reproductive roles. When


It is suggested that sexual selection has had a major influence on sexual size dimorphism in Charadrii, whereas divergence in the use of feeding resources while breeding was not supported by analyses.

A comparative study on the evolution of reversed size dimorphism in monogamous waders

The analysis of wing shape showed that males of species with acrobatic flight displays had wings with higher aspect ratio than non-acrobatic species, which probably increases flight manoeuvrability during acrobotic displays.

Path analysis and the relative importance of male–female conflict, female choice and male–male competition in water striders

Path analysis showed that male–male competition was important in favouring larger males with longer limbs that tended to be more active, and male size thus affected mating success via all three behavioural mechanisms.

Mammals in Which Females are Larger Than Males

Present knowledge about the species of mammals in which females are larger than males is quite rudimentary and much more information is needed before the authors will be able to speak of the selective pressures accounting for the phenomenon with any reasonable degree of certainty.

Sexual selection explains Rensch's rule of size dimorphism in shorebirds.

Sexual size dimorphism shows a remarkably widespread relationship to body size in the animal kingdom: within lineages, it decreases with size when females are the larger sex, but it increases with

Identifying a causal agent of sexual selection on weaponry in an insect

This work experimentally tested the hypothesis that increasing resource value increases harem size and thus increases the opportunity (I mates ) for and strength of sexual selection on traits crucial to male resource-holding potential and mating success in the Wellington tree weta, and predicted that male weapon size was under stronger directional selection in large galleries.
