No room for third party! These fish can outwit the "sneaky" male fish.
In an attempt to gather valuable shark conservation data that looks at reproduction rates and population growth, researchers from the University of North Florida have moved from common dissection to the less invasive, and maybe more interesting, method of non-lethal ultrasound.
Vast genetic changes can occur in hatchery-raised fish in as little as one generation, according to the latest study from Oregon State University. This poses a significant threat to wild populations that come in contact with their genetically unique relatives.
A Laysan albatross named Wisdom is the world's oldest banded bird. She and her mate, Goo, recently hatched yet another chick at the Midway Atoll National Wildlife Refuge in the Pacific Ocean. At age 65, this is Wisdom's 40th baby.
Previous studies suggest older parents give birth to offspring that, on average, live shorter lives. In a recent study of European shorebirds, researchers believe they have shed some new light on the matter.
National Park Service biologists recently discovered two mountain lion kittens in the Santa Monica Mountains in California. The pair's mother is thought to be a well-tracked mountain lion designated as P-19, but DNA testing is underway to confirm who their father is. Nonetheless, researchers say this successful birth highlights the habitat quality of the Santa Monica Mountains.
A mother's diet is largely responsible for keeping animal populations in check, according to a new study from the University of Edinburgh
Some prairie voles are monogamous, while others seek out multiple mates. In a recent study, researchers from the University of Texas at Austin reveal sexual behavior is largely controlled by genetic differences in the rodents' brains, suggesting natural selection has allowed for both characteristics to co-exist.
The oldest known bird -- an albatross named Wisdom -- is about to lay another egg at 64 years old. Researchers believe she has raised as many as 36 chicks and clocked over six million ocean miles of flight time.
A recent study found that the extent to which animals tolerate humans is largely driven by the environment in which they live and their body size.
Oil-based pesticides are more effective than water-based alternatives when it comes to killing brown widow spider at the source: their egg sacs.
Birds that are able to mate with their "true love" have a higher rate of reproduction success and are more committed to their offspring, according to researchers from the Max Planck Institute for Ornithology.
Researchers recently discovered that if elephants are born during times when their mothers are more stressed, they are likely to age faster and reproduce less during their lifetime.
Scientists have discovered a fern "love child" in the mountains of France and found that it is the result of a puzzling reunion, providing insight on plant reproduction, according to a new study.
