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…

In recent years, researchers have identified a small group of stalactites that appear to have calcified underwater instead of in a dry cave. The Hells Bells in…
Nature itself can be the best defense against climate change for many species — at least in the short term — according to a study published in the journal Ecology Letters…
Permafrost makes up a quarter of the landmass in the Northern Hemisphere. Climate change means that Arctic coasts are thawing and eroding at an ever greater…
Hot vents in the deep sea and geysers on land document the penetration of water into the hot interior of the Earth. This happens primarily in regions where the…
Heat from the friction of rocks caused by tidal forces could be the “engine” for the hydrothermal activity on Saturn's moon Enceladus. This presupposes that…
According to the paper in Science Advances, the artificially lit surface of Earth at night increased in radiance and extent over the past four years by 2 per…
“Leaves up at the top of the canopy are really greedy–they absorb a lot of light and don't let much down to their brothers and sisters below them,” said…
Nature whispers its stories in a faint molecular language, and Rice University scientist Laurence Yeung and colleagues can finally tell one of those stories…
Radar surveys of the land beneath Pine Island Glacier, obtained by snowmobile, have revealed a surprisingly diverse, mountainous landscape under the ice.
“Well, it is not always the case”, says Dr. Xue Wu, the corresponding author of a recently published study in Atmospheric Chemistry and Physics, “We have found…
Two crops or one? Sometimes, growing two crops simultaneously on the same piece of land – called intercropping – can benefit farmers. But it needs careful…
The Colorado River's initial trip to the ocean didn't come easy, but its story has emerged from layers of sediment preserved within tectonically active…
With less than 25,000 breeding pairs in existence today, it is an uphill battle for the African Penguin, which calls South Africa home. The 60 percent drop in…
Reservoirs of oxygen-rich iron between the Earth's core and mantle could have played a major role in Earth's history, including the breakup of supercontinents,…
