It's a bit ironic, but some ecologists actually call the world's largest species of parrotfish the "elephant of the sea." Now researchers have determined just how important - and harmful - this unusual fish is to the ocean's ecosystems.
Florida's ecosystem may be undergoing some major changes thanks to sixth-grader Lauren Arrington's research on lionfish, an invasive species.
Whales, though impressive mammals, until now were thought to be inconsequential in terms of their role in Earth's oceans. But new research from the University of Vermont has revealed that these massive creatures make a huge difference, and in fact are the ocean's main ecological engineers.
Next time you're scouring the beaches for seashells to add to your collection, think again. A study 30 years in the making has found that the removal of seashells from beaches could damage ecosystems and endanger organisms that rely on shells for their survival.
Ecuador has declared a state of emergency in the Galapagos Islands, wary that a cargo ship that ran aground last week threatens the archipelago's delicate ecosystem, reports say.
In 2006, marine biologists Craig McClain and Jim Barry used the Monterey Bay Aquarium Research Institute's remotely operated vehicle to place 36 bundles of acacia wood on the sea floor of Monterey Canyon, 3,200 meters below the surface. Five years later, they retrieved the bundles. Now, a new release from the institute details their surprising findings.
The accepted logic is that golf courses - with their extreme demands on local water reserves and constant altering of the landscape - are ecological disasters. New research out of the University of Missouri suggests a viable habitat is possible under certain conditions, and enhanced management practices may, in fact, be beneficial to ecosystems within golf courses.
Goldfish are invading Lake Tahoe in the Sierra Nevada, amid concerns that the invasive species may affect the lake's ecosystem.
A new study suggests that the reintroduction of wolves in Yellowstone National Park is not enough to restore the park's ecosystem.
Tadpoles, larva of a frog or a toad, may help in maintaining the ecosystem of freshwater streams, according to a new study.
Warming climate has forced mountain pine beetles to invade high-elevation trees that are not strong enough to defend and stop them, finds a new study.
A team of researchers has discovered that the cold-water coral is growing much deeper than seen previously in the Gulf of Mexico.
Salmon conservation shouldn't focus on managing flows in streams and rivers or on preserving only places that currently have strong salmon runs.
