To adapt to changing environments, fish have evolved with an enzyme researchers refer to as Cyp27c1, which is closely linked to vitamin A and known to promote good vision in low light.
While evolving with specialized defenses has helped animals escape predation, long-term risks need to be considered. The simple act of camouflage or mimicry, which sufficiently confuses prey, doesn't seem to have backfired, but the use of chemical defenses has. In fact, some amphibians that release lethal toxins to kill predators are now at a higher risk of extinction.
Bacteria found on some frogs' skin naturally protects the amphibian from a deadly skin disease that is already affecting 500 species of amphibians worldwide.
Over the past five years, more than 200 new species have been found in the Eastern Himalayas and noted in scientific studies.
China successfully used conservation methods to preserve giant panda populations, but researchers have pointed out some ways that a broader series of efforts could help other animals.
Florida has become home to many invasive species that are threatening the Everglades. When non-native species establish themselves, it is harder to remove them. This puts an ecosystem's biodiversity at risk.
Yale researchers discovered more female green frogs are being born in suburban ponds. They recently linked this unbalanced sex ratio to common lawn plants, such as clover.
A collaborative team of researchers recently developed an online portal for scientists studying diseases threatening global populations of amphibians, reptiles and fish. This new system could aid in future outbreaks.
In addition to the raging wildfires, the Pacific Northwest lowlands are experiencing devastation in mountain pond habitats as a result of climate change. According to recent forecast models, this just may be new norm that amphibians have to get used to.
Findings from a study involving the mating habits of female túngara frogs supports the idea that irrationality as the result of being presented with too many choices may have deep biological roots – in humans as well.
Seven new teeny-tiny frog species have recently been discovered in the cloud forests of Brazil, and though they were just found, scientists already say that they are threatened and on the brink of extinction.
Unless you live under a rock or don't own a television, you probably know who Kermit the Frog is. The beloved Muppet has captured the imaginations of the young and old alike for a stunning six decades, but we all know he's not actually real... right? Researchers have now revealed that a newly discovered species of frog in Costa Rica looks just like him, causing us to wonder if Kermit is more real than we ever thought.
The cane toad (Rhinella marina) isn't exactly a beloved amphibian. While countless frogs continue to face the troubles of climate chnage, shrinking habitats, and rampant disease, the cane toad has become an invading force in Australia - a dog-drugging nuisance without any natural predators to keep it down. But toad-hating Aussies may have hope yet. The cane toad is set to become Chinese medicine's next big import, as it was recently revealed that its poison could have cancer-fighting properties.
Scientists have discovered an incredible, shape-shifting frog species in the western Andean cloud forest of Ecuador, and it just may be the first ever amphibian that can rapidly change its skin texture, a new study says.
