Sexual conflict
TLDR
Current research with stalk-eyed flies is focussed on identification of accessory gland products and evaluating their role in mediating potential conflicts of interest between the sexes. Expand
Sexual selection and genital evolution.
TLDR
Several studies now link variation in genital morphology directly to male fertilization success, and modern comparative techniques have confirmed predicted associations between genital complexity and mating patterns across species. Expand
Sperm Competition in Fishes: The Evolution of Testis Size and Ejaculate Characteristics
TLDR
It is found that both the gonadosomatic index and sperm numbers increase with intensity of sperm competition across species but that sperm length decreases, which does not fit predictions of current sperm competition theory. Expand
Sperm Competition and Sexual Selection
TLDR
Reading sperm competition and sexual selection is also a way as one of the collective books that gives many advantages. Expand
Sperm competition games: individual assessment of sperm competition intensity by group spawners
TLDR
Three sperm competition game models devised mainly for externally fertilizing group-spawning species such as many fish predict that males should decrease their sperm expenditure as the estimated number of competitors present at a given spawning increases above two. Expand
Effects of alternative male mating strategies on characteristics of sperm production in the Atlantic salmon (Salmo salar): theoretical and empirical investigations
TLDR
Results show that parr invest relatively more heavily into total spermatogenesis, and have a larger gonosomatic index than anadromous males, which may explain how male parr, under elevated risks of sperm competition and occupying a disfavoured mating role, achieve disproportionately high fertilization success. Expand
Sperm competition games: a prospective analysis of risk assessment
TLDR
The logic of assessment of sperm Competition risk by individual males where the mechanism of sperm competition follows a ‘loaded raffle’ is developed and biological evidence for the predictions is summarized and discussed. Expand
Is oxidative stress a physiological cost of reproduction? An experimental test in house mice
TLDR
The results indicate that changes in redox status occur during reproduction in house mice, but suggest that females use mechanisms to cope with the consequences of increased energetic demands and limit oxidative stress. Expand
Female competition and its evolutionary consequences in mammals
TLDR
Evidence that female mammals compete for both resources and mates in order to secure reproductive benefits is reviewed, revealing female competition to be a potentially widespread and significant evolutionary selection pressure among mammals, particularly competition for resources among social species for which most evidence is currently available. Expand
Sperm competition in mammals
TLDR
It is concluded that understanding the selective pressures driving coevolution between male and female reproductive traits remains a major challenge for researchers in this field. Expand
