A rare Pacific seahorse was recently caught on camera off the coast of California, likely brought to the area by unusually warm El Niño waters.
A bighead carp weighing about 25 pounds was recently captured in the Minnesota River. This raises concern about potential effects invasive fish can have on the state's waterways.
An injured Northern Gannet seabird recently underwent life-saving surgery at the South Florida Wildlife Center to remove a hook from its stomach and treat two bullet wounds. Doctors say the animal has a rough road to recovery ahead.
Killer whales have been studied for the first time in their North Atlantic range. Compared to their Pacific Northwest counterparts that feast on Chinook salmon, the Atlantic dwellers prefer preying on minke whales.
Polar bears are spending more time inland as sea ice retreats in the Arctic. To reduce human-bear conflict, polar bear patrols have been set up to keep the animals away from people and homes.
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.
There is no doubt humans have left a lasting impact on the environment since the start of the Industrial Revolution. But a new study suggests people were leaving their mark much earlier: Settlers in Madagascar set forests ablaze 1,000 years ago to make room for cattle pastures.
Mysterious environmental factors combined to create a rare effect at Yosemite National Park's Horsetail Falls earlier this month.
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.
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.
In a series of marine-disease studies, researchers have for the first time linked warming oceans to the rise of lobster shell disease in New England and to the sea star wasting disease plaguing the U.S. West Coast.
