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.

Studying a species of beetle mite, an international research team has demonstrated for the first time that animals can survive over very long periods of time (possibly millions of years) entirely ...

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 ...

Asexual reproduction, in which females reproduce without males by cloning themselves, has been documented in multiple species ...

Animals possess circadian clocks, or 24 h oscillators, to regulate daily behavior. These typically take their cues from the periodic change of sunlight and darkness. However, many animals are also ...

Fruit flies that normally must mate to reproduce can be genetically modified to give birth asexually for generations to come The common fruit fly normally needs a mate to reproduce. But scientists ...

It is an awkward idea, but a couple's ability to have kids may partly depend on who else is present. The reproductive tracts of males and females contain whole communities of micro-organisms. These ...

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 ...
