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 ...

While most of us know baby horses are adorable, the majority of people don’t realize the process involved in equine ...

Animal mothers exhibit remarkable resilience and ingenuity when raising large litters. Species like the tailless tenrec and ...

Dominance interactions determine reproductive status in many animal societies, including many cooperatively breeding vertebrates and eusocial Hymenoptera without queen-worker dimorphism. Typically, ...

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 ...

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.

Why do animals engage in sexual reproduction? Biologists sought answers with mud snails that breed both sexually and asexually. They found that asexual snails grow faster and reach reproductive age ...

Diabetes mellitus has emerged as a critical factor influencing male reproductive health in animal models, with sustained hyperglycaemia leading to a spectrum of testicular dysfunctions. Experimental ...

The mating game in the animal kingdom is nothing less than fascinating and somewhat weird. Some species pierce, clone, chew, or even fake their way through the mating process. To make survival ...

American zoologist Laurie Marker has been collecting and storing specimens in a cheetah sperm bank in Namibia for 35 years, ...

In the animal kingdom, penises can be spiked, split, corkscrewed—even detachable. They're one of the most diverse structures ...
