Over generations, a small North American frog has learned how to survive in a world that's getting increasingly saltier. But new research from the University of Missouri suggests that adaptation comes with an unexpected trade-off.
Scientists have long posited that the earliest water animals to transition to land had amphibious tadpole features, going through a metamorphosis akin to that of today's frogs.
When trying to attract and recognize potential mates, animals are known to rely on various signals, traits and behaviors. In the case of birds, these signals can typically include a wide range of sounds—such as trills, whistles, ...
Over 300 million years ago, a minnow-sized fish died and fell to the bottom of a prehistoric swamp near the village of Trawden, Lancashire, in northwest England. The remains of this tiny fish—known as Trawdenia planti—became ...
A new estimate of insect species globally finds that there may be 8 million to 14 million more species than people thought, with few of them discovered.
When major infrastructure projects are built in rural areas, wildlife is often displaced and moved out of the way. This is called mitigation translocation, and it is a globally recognized method for moving animals. However, ...
For her doctoral dissertation, Yale's Nathalie Alomar decided to study a small amphibian that appeared to have eluded the forces of evolution. She found that there is more to its evolution than meets the eye.
Tropical rainforest patches perched on isolated granite mountains in northern Mozambique have yielded four new species of sylvan chameleons, according to a new study by Prof. Krystal A. Tolley and Dr. Werner Conradie, recently ...
Like humans, wildlife is increasingly vulnerable as climate change fuels longer and more intense heat waves, disrupting feeding and breeding and, in extreme cases, proving fatal.
Life on our planet began in the water. Eventually, one branch of the fish family tree developed legs and came up on land. These early four-legged animals, the tetrapods, were the forebears of today's mammals, birds, reptiles ...
