... Timing of seasonal reproduction by flying-foxes is apparently dependent on an endogenous circannual rhythm, coded in their genome. Ultimately, evolution of an endogenous rhythm aligns an important reproductive stage, such as lactation, with resource availability such as the occurrence of maximum...

... population viability would also be compromised. This argument can be countered by the persistence of populations under harvesting without any obvious impairment to reproduction. Nevertheless, an interesting question is how age influences reproductive output. In this study, data collected from a number of red...

... Flying-fox species worldwide are under threat of extinction. Artificial insemination (AI) has the potential to play a primary role in the conservation of endangered flying-foxes, through the genetic and reproductive management of captive colonies.
