Exempel på hur man kan använda COPULATIONS i en mening

• Another behavior that is relatively frequent in European pied flycatchers is the practice of extra-pair copulations (EPC).
• Male snakes giving off both male and female pheromones have been shown to garner more copulations than normal males in the mating balls that form at the den when females enter the mating melee.
• Indeed, in orangutans, close human relatives, such copulations constitute up to half of observed matings.
• The decline in libido is not enough to account for reduced fertility in heavy cocks at 58 weeks and is probably a consequence of the large bulk or the conformation of the males at this age interfering in some way with the transfer of semen during copulations which otherwise look normal.
• Male philopatry, extra-pack copulations and inbreeding avoidance in Ethiopian wolves Canis simensis.
• One behavior that molecular data has helped scientists better understand is extra-pair fertilizations (EPFs), also known as extra-pair copulations (EPCs).
• In a lekking shorebird species, the ruff, or Philomachus pugnax, there are three distinct male morphs: independent males, the primary, dark-feathered morph, which establishes and aggressively defends a lekking territory, satellite males, a light-feathered morph which does not defend its own territory but which seeks prominent independent males to display alongside, and faeder males, which lack the typical male breeding plumage, instead more closely resembling females, possess a smaller body size, intermediate between a typical male and female, and which do not consistently occupy a single territory, but move freely between different independent male territories, perhaps owing to their female-like plumage, and engage in sneak copulations with females.
• Once a mate has been selected, several copulations occur during which the male inserts his claspers, which are paired intromittent organs, into the female's vagina.
• barbicornis are often too small to joust with their rostra, yet too large to engage in 'sneaking' copulations.
• Subsequent copulations force the spermatophore ampulla out of the female where it then adheres to the base of her ovipositor.
• Even though monandrous female experiencing multiple copulations can produce more eggs than polyandrous female experiencing multiple copulations, monandrous females produce less offspring that survive into adulthood than polyandrous females do.
• For example, female superb fairywrens (Malurus cyaneus), are a monogamous bird that perform extra-pair copulations during matutinal hours.
• The highest known frequency of reproductively successful extra-pair copulations are found among fairywrens Malurus splendens and Malurus cyaneus where more than 65% of chicks are fathered by males outside the supposed breeding pair.
• These pre-copulatory pairs are often initiated around a week before parturial ecdysis because the male wants to monopolize copulations of the female.
• Emasculation thus synchronizes sexual cannibalism and sperm transfer, lengthening the interval between copulations.
• Besides, the union of Yin and Yang in sexual life should not be wholly given up, for if a man does not have intercourse he will contract the diseases of obstruction and blockage by his slothful sitting, and end by those which arise from celibate depression and pent-up resentment—what good will that do for his longevity? On the other hand, over-indulgence diminishes the lifespan, and it is only by managing copulations so that the seminal dispersals are moderated, that damage can be avoided.
