Animal reproduction and breeding encompasses the full spectrum of natural, assisted and genetic processes that underpin the perpetuation, improvement and conservation of species across diverse taxa.

The energy invested in animal reproduction is as much as 10 times greater than previously estimated when the metabolic load of bearing and caring for offspring is accounted for, according to a new ...

A large-scale analysis of 117 mammal species found that preventing reproduction is associated with longer lifespans, suggesting a strong link between reproductive activity and life expectancy. Why do ...

In animals, releasing eggs in a timely manner is vital to maximize the chances of successful fertilization. However, how this process evolved and is controlled in different species is poorly ...

For the first time, scientists have induced facultative parthenogenesis, a form of asexual reproduction, in an animal that usually reproduces sexually. An estimated 76 percent of fruit flies can ...

Ocean pollution is unfortunately becoming more commonplace, raising concerns over the effect of chemicals that are leaching into the water. In a new study, researchers have discovered how these ...

While sexual reproduction in animals is the norm, many species are capable of parthenogenesis: that is normal development in the absence of fertilization. For example in vast insect order Hymenoptera ...
