Bison adjust their diet seasonally based on reduced availability of the grasses they perfer but are less nutritious during the spring and fall.
Gentoo penguins, an arctic species distributed around the South Pole, have evolved a special method to remian ice-free, say researchers who are now hoping to adapt their findings to airplane wings which frequently need de-icing. "It's a little ironic that a bird that doesn't fly could one day help airplanes fly more safely," said one researcher.
Hummingbirds are muscling through many of their aerial performances, says a new study.
Camouflage is a adaptable trait used not only to hide from predators, but to sneak up on prey. Researchers recently revealed horned praying mantises have re-evolved with disruptive camouflage abilities, similar to those found in ancient lineages of the iconic insects.
Wild animals living within the Ruaha National Park, located in Central Tanzania, routinely dig watering holes to beat the heat during the dry season.
Venom is both a predatory defense and a predator's advantage. While some venomous animals have recently evolved with more potent toxins, their ancient counterparts diversified less often. This suggests that the evolution of venom is more complex than previously thought.
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.
Some butterflies have developed a toxic chemical that makes them poisonous to some birds. However, birds recognize which butterflies are lethal and avoid eating them. Since not all butterflies are equipped with such predatory defenses, they mimic their lethal counterparts and trick birds into thinking they are poisonous too.
Rooftop bugs may provide valuable insight regarding climate change and how speceis adapt, relocate or die.
The discovery of a new speies of Malaysian snail has set the world record for tiniest land snail species. The previous record was set early this year by a species discovered in China.
Rhesus monkeys rely on their sense of smell more heavily than researchers previously thought, employing it to distinguish between members of their own social groups and those who don't belong.
Plants and animals alter their behaviors based on the seasons. Humans, it turns out, are no different. Here are just a few ways we change with the season.
Cowbirds lay their eggs in neighboring nests and abandon the to be raised by surrogate bird parents. Researchers recently spent some attempting to figure out whether the birds know they are different from their adopted families and how they handle it in terms of feeding, mating and flocking.
Researchers found that pineapples utilize a unique photosynthesis that protects the plants from loosing too much water during the day. This allows the fruits to be juicy even though they grow in dry environments.
Iberian lynx fossils dating to 1.6 million years ago were recently recovered from a cave in Barcelona, Spain. It's the oldest lynx specimen ever found, suggesting the species arrived in the area 500,000 years earlier than originally estimated.
