Assisted reproductive technology (ART) is increasingly being used to facilitate conception in both clinical and veterinary medicine. Infertility rates are on the rise amongst the global human ...

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.

This is a preview. Log in through your library . Abstract A synopsis is provided of different expressions of whole-animal vertebrate clonality (asexual organismal-level reproduction), both in the ...

A new study shows there is a high cost of parenthood, quantifying the 10% “longevity tax” on reproduction. Consequently, mammals that have fewer or no offspring tend to live longer. But why does ...

A new study published in Science and led by Monash University biologists reveals that the energy cost of reproduction is far greater than previously believed. The research, led by Dr. Samuel C Ginther ...

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 ...

New research shows that epaulette sharks, often called “walking sharks,” can produce eggs without increasing their overall energy use.

RIVERSIDE, Calif. – Two paleontologists studying ancient fossils they excavated in the South Australian outback argue that Earth’s ecosystem has been complex for hundreds of millions of years – at ...

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 ...

Reproduction in animals varies from species to species. Some types of reproduction, like parthenogenesis, are more unusual than others. This reproductive method requires only one individual rather ...

Many mammal populations in European and North American zoos are aging – a trend that jeopardizes the long-term viability of so-called reserve populations and, with it, a core mission of modern zoos in ...
