Reproductive biology

Most fruit bats have two breeding seasons a year, although the females of most species only conceive in one of the seasons. They tend to be polygamous with males attempting to mate with as many females as possible (although many do not mate at all) and females mating with two or more males. There is at least one species that is believed to be monogamous. Delayed

implantation occurs in some species. The ovum is fertilized, but the zygote goes into stasis rather than implanting in the uterine wall. When conditions are right the zygote is implanted and begins development. Births are usually synchronized to correspond with the period of greatest food availability. Single births are the norm. Gestation is between four and six months.
