Butterflyfish depend on food and shelter provided by coral reefs, but they steer clear of those that have come in contact with seaweed. Researchers suggest this may be a strong indicator of their awareness of reef health.
Genome sequencing, paired with a behavioral test, identified several genes linked to anxiety in chickens. Researchers believe the same genes may play a role in mouse and human behavior.
Plants growing in close quarters constantly compete for sunlight, which is essential to their survival. When a plants is shaded from the sun – either by a cloud overhead or competing plant growing next to it – light sensors kick in to trigger growth.
A pack of rats recently killed 14 orange-bellied parrots housed at a captive breeding facility in Tasmania. These birds are part of a national recovery program working to replenish the species' dwindling population.
A new species of roundworm discovered on Reunion Island in the Indian Ocean boasts some interesting characteristics. Researchers say this nematode that lives in fig trees can develop five different specialized "faces" or mouths, based on the available food supply.
Earth's largest apes died off because they could not adapt to a new diet forced by climate change 100,000 years ago.
Tropical cyclones - also known as typhoons - disperse powerful winds that can have a dramatic impact on nutrient cycling of an ecosystem. Island nations in the western Pacific and native plants in this region seem to be hit the hardest by these massive storms.
Vultures are not good at flapping their wings, but they manage to spend long periods of time in the air by soaring. Researchers found that these birds stay aloft by making use of small-scale turbulence that produces uplift without flapping their wings.
Virgin births, scientifically called parthenogenesis, may be more common among snakes than previously thought. Understanding this sort of reproduction sheds light on the evolutionary history of vertebrates, researchers say.
Asian carp pose a major risk to Lake Erie's ecosystem. New computer models suggest these invasive fish could soon throw off the balance of the natural food chain and account for nearly a third of the lake's total fish population.
The Florida Fish and Wildlife Conservation Commission reinstated the “python challenge," which will run from Jan. 16 through Feb. 14 this year. Participants compete to catch the largest and longest Burmese pythons, as a means of protecting the Everglades National Park.
Male wild guinea pigs pass down their ability to adjust to environmental changes to their sons. Researchers suggest future generations could benefit from this "epigenetic information" as climate change causes global temperatures to rise.
Tiny chameleons have surprisingly powerful tongues, researchers reveal in a new study. Like all small animals, these lizards need to consume more energy per body weight to survive. Therefore they have to shoot out their tongues unusually fast and far in order to compete with larger relatives for insect meals.
Humpback whales are spending some extra time up north in Alaska this season. Experts say the whales are slow to arrive at breeding grounds in Hawaii because of possible food competition or El Niño disruptions.
Although colonies of Florida carpenter ants have designated roles, researchers managed to turn foraging ants into scouts with the use of epigenetic drugs. This suggests social behavior is not necessarily based on an individual's genetics.
