Male Weaponry in a Fighting Cricket
TLDR
Results are the first evidence that the size of the head capsule and mouthparts are under positive selection via male-male competition in field crickets, and validate 800-year-old Chinese traditional knowledge. Expand
Condition Dependence of Male Life Span and Calling Effort in a Field Cricket
TLDR
These findings suggest that male quality and survival are positively correlated, but more tests of this hypothesis are needed. Expand
Chorus participation by male bullfrogs, Rana catesbeiana: a test of the energetic constraint hypothesis
TLDR
Evidence is found that direct selection through endurance rivalry favoured traits in male bullfrogs that increased tenure, and the energetic constraint hypothesis did not adequately predict variation in male chorus tenure. Expand
The relative effects of mating status and age on the mating behaviour of female field crickets
TLDR
It is found that virgin females were both more likely to mate and copulated more quickly than mated females, but female age had no significant effect on either the probability of mating or the latency to copulate, showing that mating status is more important in determining female mating behaviour than age. Expand
Do male field crickets, Gryllus pennsylvanicus, signal their age?
TLDR
A simple mechanism is suggested that explains both female preference for older males and female discrimination against heterospecific males is suggested, and the majority of information in male song appears to be related to body size. Expand
Female social experience affects the shape of sexual selection on males
TLDR
Experienced females exerted significant positive directional selection on male weaponry size and favoured older males, however, linear variation in these traits did not affect the probability of an inexperienced female mating. Expand
A lover, not a fighter: mating causes male crickets to lose fights
TLDR
It is suggested that mating is itself detrimental to male success in aggressive contests, but that this effect is not sufficient to eliminate the effect of RHP on fighting success. Expand
Multivariate sexual selection on male song structure in wild populations of sagebrush crickets, Cyphoderris strepitans (Orthoptera: Haglidae)
TLDR
A complex pattern of multivariate nonlinear selection characterized primarily by strong stabilizing and disruptive selection on male song traits is revealed, suggesting that the female auditory system is tightly tuned to the species-specific call frequency. Expand
Interactions between naturalised exotic salmonids and reintroduced Atlantic salmon in a Lake Ontario tributary
TLDR
This study released hatchery-reared adult Atlantic salmon into a Lake Ontario tributary to examine spawning interactions between this species and fall-spawning exotic salmonids found in the same stream and found that interspecific courtship was the most common form of exotic interaction with spawning Atlantic salmon. Expand
Small-male mating advantage in a species of Jerusalem cricket (Orthoptera: Stenopelmatinae: Stenopelmatus)
TLDR
This paper demonstrates female-biased size dimorphism and a strong copulatory advantage for small males in a Jerusalem cricket (JC) (Stenopelmatus) from central California, believed to be the first example of small-male advantage based solely on the physical aspects of copulation. Expand
