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.
The Toronto Zoo's newest addition is a baby Indian rhino, a species currently listed as vulnerable on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species.
Mysterious environmental factors combined to create a rare effect at Yosemite National Park's Horsetail Falls earlier this month.
Animal shelter staff often misidentify dogs as pit bulls, solely based on appearance. As a result, they are less likely to be adopted.
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.
It has long been thought that Easter Island's early Rapa Nui civilization collapsed due to lack of a lack of resources that eventually led to war. This theory was based on war-like weaponry scattered across the island. A new study, however, disproves the theory, stating the artifacts are nothing more than tools.
After Thailand's Huai Kha Khaeng Wildlife Sanctuary beefed up patrols for poachers starting in 2005, tiger populations grew substantially. This is an outstanding conservation success, say researchers, but they also warn that continued patrolling is needed to ensure that populations of prey grow to meet the food demands of more tigers.
Tiny marine snails known as sea butterflies appear to "fly" underwater much like winged insects do when taking to the sky – representsing a remarkable example of convergent evolution, where two unrelated species develop features that are used in similar ways.
A rare Franciscana dolphin – just a baby – was the tragic victim of too much enthusiasm and even more ignorance from beach goers in Santa Terisita, Argentina.
The Michigan Department of Natural Resources estimates that the state's elk population has doubled within the last two years, totaling some 1,371 animals today.
Officials at Australia's Bondi Beach are testing a new way to detect when sharks get too close to coastal swimmers. The technology, called Clever Buoy, senses when sharks are in the area and, via an app, alerts authorities who warn people when to get out of the water.
MyShake, a new app created by the University of California at Berkeley and app developers at Deutsche Telekom AG, allows smartphone users to detect nearby earthquake activity sooner and send the information directly to seismologists. The hope is to create a large enough network to provide advanced warnings to areas that lack the technology for earthquake detection.
More than 120 Morelet's crocodiles were found dead after suffocating and crushing one another while traveling to a wildlife facility in Mexico.
Vast genetic changes can occur in hatchery-raised fish in as little as one generation, according to the latest study from Oregon State University. This poses a significant threat to wild populations that come in contact with their genetically unique relatives.
Unusual fossil tracks found in northern China have baffled scientists for years because they suggest that these very large four-legged dinosaurs called Sauropods might have been able to walk on two feet. The debate has raged on for years in scientific circles but now it seems to be settled.
