Throughout history, important cities around the world have flourished along river banks. But rivers can also be destructive forces. They routinely flood, and on rare occasions, they can abruptly shift pathways.
During heavy storms, the normally stratified layers of water in ocean fjords get mixed, which leads to oxygenation of the fjord floor. But these storm events also result in a spike in methane emissions from fjords to the atmosphere.
The global food trade is often blamed for accelerating the destruction of biodiversity in poorer tropical countries, to fuel the appetites of richer nations for fruit, coffee, soybeans, beef, and palm oil.
If that lockdown goldfish is starting to lose its lustre, think twice before throwing it in the river or canal – the creatures may look innocent but their voracious appetite, tolerance for cold and have-a-go habits compared with native species can be catastrophic for local wildlife.
The start-up Running Tide wants to use kelp buoys to fight climate change. The plan might not work, but it’s still a preview of our climate future.

Mouse deer are among the smallest ruminants in the world. Today, they live in the tropics of Africa and Asia and are barely larger than hares. Males and females differ little in appearance. But that was not the case about eleven million years ago.
The Tibetan highlands have a special significance both as a grazing ecosystem and global carbon store. Furthermore, it plays a key role in the formation of the monsoon and supplying of potable water for a fifth of the earth's population.
Plants—they're just like us, with unique techniques for handling stress. To save one of the most important crops on Earth from extreme climate swings, scientists are mapping out plants' own stress-busting strategies.
No vertebrate (fish, mammal, bird, reptile, or amphibian) has ever had an odd number of limbs. Despite this "forbidden phenotype," some animals seem to use other body parts as a third or fifth "limb" to move from one place to another.
An unusual technique for catching scallops that was stumbled upon accidentally by scientists could potentially reduce some of the damage caused to our seabeds by fishing.
It’s no secret that Earth’s biodiversity is at risk. According to the International Union for the Conservation of Nature, 26% of all mammals, 14% of birds and 41% of amphibians are currently threatened worldwide, mainly due to human impacts such as climate change and development.
More than 98% of U.S. waters outside the central Pacific Ocean are not part of a marine protected area, and the ones that are tend to be "lightly" or "minimally" protected from damaging human activity, research led by Oregon State University shows.
Ants may be the unlikely heroes when it comes to better understanding the health of our planet in the midst of a climate crisis. In a paper published to Frontiers in Remote Sensing, a team of scientists, including those from NASA, have found a way to estimate the depth of snow from orbit using a ...
New research predicts that changes in mountain snowmelt will shift peak streamflows to much earlier in the year for the vast Colorado River Basin, altering reservoir management and irrigation across the entire region.
In Nigeria, about 90% of water available for drinking is sourced from boreholes, or deep, narrow wells that tap into naturally occurring underground water. A recent study in Environmental Toxicology & Chemistry found that microplastics (MPs) are abundant in the drinking water of these boreholes.
Most bottom-dwelling marine invertebrate animals, such as sponges, corals, worms and oysters, produce tiny larvae that swim in the ocean prior to attaching to the seafloor and transforming into juveniles.
Amphibians evolved from a fish ancestor that had functional lungs and bony lobed fins, which helped them become the first vertebrates to conquer land. Keeping these earlier trails, today’s frogs and toads also have larvae with gills that need an aquatic environment until they transform into air- ...
