Climate change is a global issue that is urgently needed to be addressed carefully and with haste due to its major impact on the environment and our health.
Sharks have a reputation for having large appetites, but it appears that reef sharks are remarkably light eaters. After pumping the stomachs of black-tip, white-tip and grey reef sharks, researchers found the animals eat small meals infrequently and opportunistically.
Alligators are growing much smaller and reproducing less in the Florida Everglades. As an indicator species, this suggests the local ecosystem is in poor health, which puts dozens of other threatened and endangered species at risk, too.
A huge number, 150,000, of Adélie penguins have disappeared from Antarctica's Commonwealth Bay. A recent study tied the occurrence to a giant iceberg that grounded in the area, isolating the penguins and causing them to starve to death. But critics are challenging that claim, suggesting that the birds relocated, instead.
In recent years, Florida wildlife officials have been concerned the growing population of rhesus macaques living in Silver Springs State Park. They feared the nonnative animals were taking a toll on the region's ecosystem and had the potential to transmit diseases. But a new study by San Diego State University biologists proves otherwise.
When a giant iceberg crashed down in Commonwealth Bay, Antarctica, in 2010 it isolated a colony of Adélie penguins. Having to trek much farther for food, 150,000 penguins have died, putting the colony at risk of extinction.
Bears pack on fat when preparing to hibernate each winter. To avoid the health risks often associated with human obesity, the bears have specialized gut microbiota that takes in more energy from food in the summer.
Burned and cracked tortoise shells found inside Qesem Cave near Tel Aviv, Israel, suggest early hunter gatherers enjoyed snacking on roasted tortoise shells. However, researchers say the tortoises would have only been a side dish, as they would not have provided enough calories.
Storks and other European birds have been cutting their annual migrations to Africa short by stopping to feed at nearby landfills. Researchers say consuming "junk food" is unhealthy, and when the birds alter their travel plans they disrupt ecosystems both at home and at their winter destinations.
In the face of a challenge, practice makes perfect for grey squirrels. Researchers from the University of Exeter found that squirrels were able to quickly learn which lever to either push or pull to release food from a closed box when they remained persistent.
A dozen giant sperm whales have found themselves stranded along the Dutch island of Texel and the German islands of Wangerooge and Helgoland this year. Experts say many made made wrong turns toward the coast after becoming disoriented.
A mother's diet is largely responsible for keeping animal populations in check, according to a new study from the University of Edinburgh
In a 2014 survey of Morocco's island of Mogador, raptors called Eleonora's falcons were observed engaging in a what researchers called a new behaviour that ensures their offspring receive the freshest of meats: imprisoning smaller live birds before killing and feeding them to their young several days later.
Hydroelectric dams planned for the tropical rivers of Mekong, Amazon and Congo could destroy local fish habitats and cause human populations to relocate, too. A team of researchers suggest new ways to evaluate the cost and benefits of these massive structures.
While we've been pretty sure for a while that neonicotinioid insecticides threaten honeybees, here is new information on threats from pesticides commonly used on some of the U.S.'s key crops, suggesting our government needs to increase regulation on some agricultural practices.
