New study finds that the nutritional value of prey within a single species can widely vary, offering key insights for food web dynamics and ecosystem change The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume? Following a period of massive starvation among animals living along the California coast, University of California…
Vast quantities of ocean water circulate through the seafloor, flowing through the volcanic rock of the upper oceanic crust. A new study by scientists at UC…
This study appears 50 years after a classic paper by Drs. Paul Ehrlich and Peter Raven that formally introduced the concept of coevolution using butterflies…
Modern crocodilian mothers guard their eggs and young, but without any direct fossil evidence, scientists could only hypothesize that ancient crocodiles were…
Islands are seen as natural laboratories for the study of evolution. They form isolated ecosystems with barriers to migration. Classical Island Theory predicts…

Scientists are expecting that this year's Gulf of Mexico hypoxic zone, also called the “dead zone,” will be approximately 5,483 square miles or about the size…
Satellites fill a void by providing a more complete view of remote reefs. The information is monitored globally through Coral Reef Watch, an online tool that…
Global agricultural production will need to supply substantially more feed, food, and bioenergy in the coming decades, but most fertile lands are already under…
Human consumption is rapidly draining about a third of its largest groundwater basins, despite having little to no accurate data about how much water remains…
For decades, researchers have debated the climate history of Mars and how the planet’s early climate led to the many water-carved channels seen today.
For more than 30 million years after dinosaurs first appeared, they remained inexplicably rare near the equator, where only a few small-bodied meat-eating…
Being a “computer guy from San Antonio,” now-farmer Larry Johnson says he didn’t know anything about plants – he just wanted to do something outside. Rather…
On June 12 at 15:00 UTC (11:00 a.m. EDT) NOAA's GOES-West satellite captured a visible image of tropical storm Carlos that showed bands of thunderstorms being…
The age of the Grand Canyon (USA) has been studied for years, with recent technological advances facilitating new attempts to determine when erosion of this…
Most of us don’t consider forests a source of pollution. As natural bodies, they should be good for the environment. But a recent study in Japan shows that…
