xplores the various methods of animal reproduction, highlighting the dependency of young animals on their parents, particularly in mammals, birds, and amphibians. It explains both asexual reproduction ...

The intensification of livestock production systems is a prerequisite to meet the growing demand for animal products. Genetic selection, assisted reproductive technologies and optimized reproduction ...

In the animal kingdom, reproduction is a necessary part of species survival. Parthenogenesis, a form of asexual reproduction where embryos develop from unfertilized eggs, has been observed in captive ...

I probably don't need to tell you that, although they're among our most basic biological functions as human beings, conception and pregnancy are basically the closest any of us are ever going to get ...

Not all species need sperm to fertilize an egg for sexual reproduction. Some species need sperm in order to induce completion of egg nucleus development, but then never use the sperm’s DNA. I describe ...

The vast majority of animals need to breed to reproduce. But a small subset of animals can have offspring without mating. The process, called parthenogenesis, allows creatures from honey bees to ...

How do animals decide when to fight and when to walk, fly, slither, or swim away? Most research on animal conflict has focused on the short-term costs of single interactions, but a pair of behavioral ...

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 ...

Institute of Animal Reproduction and Food Research, PAS has the following research output in the current window (1 January 2025 - 31 December 2025) of the Nature Index. Click on Count to view a list ...

Animal reproduction encompasses the full sequence from gamete formation through fertilisation, embryonic development and parturition. In farm and companion species alike, natural breeding is ...
