Sperm competition theory suggests that males should strategically allocate sperm to those females that will bring them the best possible genetic returns. Although males of a number of species of insects and fishes have been shown to allocate sperm strategically, we provide, to our knowledge, the first evidence that an avian species is also capable of allocating ejaculates. Male Adélie penguins (Pygoscelis adeliae) are more likely to transfer sperm during extra–pair copulations (EPCs) than…

Ejaculate allocation by male sand martins, Riparia riparia
A more detailed examination of the ejaculate patterns of individual males, achieved by the DNA profiling of ejaculates, provided additional evidence for strategic allocation of sperm.
Sophisticated sperm allocation in male fowl
The results indicate that female promiscuity leads to the evolution of sophisticated male sexual behaviour in birds, and male sperm allocation of unprecedented sophistication in the fowl Gallus gallus is demonstrated.
It is suggested that males have evolved sophisticated patterns of sperm allocation to respond to frequent fluctuations in the value and frequency of reproductive opportunities.
Male mating behavior and ejaculate expenditure under sperm competition risk in the eastern mosquitofish
This hypothesis that males should tailor the size of their ejaculates according to temporal changes in the risk of sperm competition is tested by using the eastern mosquitofish, a freshwater species of fish exhibiting a coercive mating system and internal fertilization.
Courting virtual rivals increase ejaculate size in sticklebacks (Gasterosteus aculeatus)
It is shown that males invest significantly more sperm (absolutely and relatively with respect to available sperm in the testes) after the courting stimulus, suggesting that the evolutionary force of sperm competition has led to precise mechanisms of future risk assessment.
Sperm: seminal fluid interactions and the adjustment of sperm quality in relation to female attractiveness
It is shown that dominant males increase the velocity of the sperm they invest in more attractive females by allocating larger ejaculates that contain seminal fluid that increases sperm velocity.
No Plastic Responses to Experimental Manipulation of Sperm Competition per se in a Free‐Living Flatworm
The results suggest that M. lignano does not have the ability to detect sperm competition per se, as worms experimentally exposed to the presence or absence of sperm competition did not differ in sex allocation, sperm transfer or mating behavior.
Individual adjustment of sperm expenditure accords with sperm competition theory
Sperm expenditure is measured in two gobiid fishes, the grass and black goby, in which up to six sneakers can congregate around the nest of territorial males and release their sperm when females spawn to show that, in accordance with theory, sneaker males of both species release fewer sperm as the number of competitors increases.


Ejaculate quality and the success of extra-pair copulations in the zebra finch
It is reported that the swimming velocity of sperm of the zebra finch, Taeniopygia guttata, varies predictably within males, and is determined, together with sperm numbers, by the time since last ejaculation.
Ejaculate size varies with socio‐sexual situation in an insect
It is concluded that male T.molitor adjust the number of sperm they inseminate according to some perception of the risk of sperm competition, and males subjected to both long‐term and short‐term exposure to potential intrasexual competitors demonstrated the ability to adjust their ejaculate according to socio‐sexual situation.
Ejaculate Cost and Male Choice
The problems of limited ejaculatory capacity and male choice merit greater attention in both theory and in empirical research.
Sperm Transfer in the Adélie Penguin
This study looks at sperm transfer in a wild population of Ad6lie Penguins by combining behavioral observations of cloacal contact and ejaculate transfer with collection of ejaculates and identification of presence or absence of sperm by microscopic examination.
Risk of sperm competition directly affects ejaculate size in the Mediterranean fruit fly

Ejaculation strategies for cases when an opportunist male ‘steals’ a mating with the female of a paired male are examined, an evolutionary game of competitive ejaculation in which two (or more) males mate with the same female.
Sperm precedence in zebra finches does not require special mechanisms of sperm competition
It is shown that empirically measured rates of disappearance of sperm from the reproductive tract, and differences in the number of sperm in the first and subsequent ejaculates of each male, are sufficient to account for observed levels of sperm precedence in zebra finches Taeniopygia guttata.
Mate Switching and Copulation Behaviour in the Adélie Penguin
A high frequency of copulation may have evolved in pair males to protect paternity against initial males in this species of penguin, and there is no support for last male sperm precedence from either diurnal or seasonal patterns of copulations relative to fertilisation.
Extra-pair copulation and sperm competition in the zebra finch
It is shown that EPCs occurring under semi-natural conditions in captivity result in extra-pair paternity, and sperm from the last male to mate has precedence over previous matings: a single EPC occurring last is disproportionately successful in fertilizing eggs, butEPCs followed by further pair copulations have a low probability of success.
Male crickets increase sperm number in relation to competition and female size
Abstract There is evidence to suggest that males of various species can respond to the threat of sperm competition by varying the amount of sperm transferred during copulation. We tested this in two
