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 ...

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.

Abstract: Attempts to account for observed variation in the degree of reproductive skew among cooperative breeders have usually assumed that subordinate breeding has fitness costs to dominant females.

Scientists compared genomes from 154 animal species and found that land animals share genetic tricks for surviving outside ...

In the framework of an international research project, a team of scientists have demonstrated for the first time that asexual reproduction can be successful in the long term. The animal they studied ...

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 ...

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 ...

Availability of adequate nutrition and (rearing) density are among the most important factors affecting growth, development and reproduction in animals. In holometabolous insects diets and energetic ...

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 ...

The peppered moth is an iconic example of Charles Darwin’s theory of evolution by natural selection. For centuries peppered moths (Biston betularia) were common in the forests around Manchester, ...

Human women typically go through menopause between ages 45 and 55, when they undergo hormonal changes that cause them to stop being able to reproduce. But they're not the only ones in the animal ...
