Sharks eating seagrass? Sounds fishy, but the reality is that animals don't conform to the strict categories we try to place on their diets.
Missing the wood for the trees.
Planting trees is a popular way for companies to clean up their image. Unfortunately, it may cause more problems than it solves.
Fossa (Cryptoprocta ferox) at the Houston Zoo.
The fossa, Madagascar's largest predator, is a cat-like carnivore that eats everything from insects to lemurs. Because they are rare and elusive, scientists know very little about them, including how many there are.
Rainforests may have played far more of a role in shaping human evolution than previously thought.
The 2016 Maple fire (photographed in July 2017) reburned young forests that had regenerated after the 1988 Yellowstone fires. More frequent high-severity fires are expected in the future as climate warms, which may change patterns of forest recovery.
Huge fires roared through Yellowstone National Park in the summer of 1988, scorching one-third of the park. Since then the park has been a valuable lab for studying how forests recover from fires.
Successive governments have seen the Great Barrier Reef not just as a scientific wonder, but as a channel to further economic development.
The $444 million awarded to the Great Barrier Reef Foundation has been criticised as a politically calculated move. But governments have been asking what the reef can do for them ever since colonial times.
Down House: the home (and garden) of Charles Darwin.
Was Darwin inspired by the tropical wildlife of his travels to discover natural selection? Actually, pigeons, worms and barnacles were far more prominent in his thinking.
Smiles all round for Britain’s adders.
It's a bumper year for lizards, a mixed bag for butterflies and a dismal time for frogs and toads ...
Forest near Sarayaku, Ecuador.
What drives the emergence and disappearance of species? By modeling the fundamental processes of evolution and ecology on geographical scales, new research spotlights topography and climatic shifts.
New findings from the Chagos Islands are a perfect parable for the Anthropocene.

We have long wondered why Earth has stayed habitable enough for life to evolve over billions of years.
Ken Starkey defends the importance of business schools, while Martin Parker says 'bring in the bulldozers'.
Marx believed that exploitation of workers and of nature went hand-in-hand.
The large human brain has been thought to result from social demands. But new research challenges this idea.
Panamanian golden frogs (
Atelopus zeteki) are listed as critically endangered, and may be extinct in the wild.
Chytrid fungus has caused a global "amphibian apocalypse," killing frogs worldwide. Now some appear to be evolving resistance – but a closely related fungus threatens newts and salamanders.
Some studies show that female lions prefer darker coloured manes to bigger manes.
People used to think that boy lions had big shaggy manes to protect their necks from being bitten or scratched during fights. But scientists soon realised this idea didn't make much sense.
Eyes in the sky: drone footage is becoming a vital tool for monitoring ecosystems.
Deakin Marine Mapping Group
Ecology is in the midst of a technological revolution. From tiny sensors that can be fitted to animals, to swarms of remotely-piloted drones, researchers have a host of new ways to study the natural world.
Long-eared Myotis bat (
Myotis septentrionalis), photographed in Arizona.
Scientists often use animals and plants as indicators to assess whether ecosystems are polluted. Tracking bats, which cover wide areas and need clean water, could become a way to find potable water.

Politicians and economists call for emissions cuts while also embracing free trade – they can't have it both ways.
Little Missouri River, North Dakota.
Recent research shows that US rivers are becoming saltier and more alkaline. Salt pollution threatens drinking water supplies and freshwater ecosystems, but there is no broad system for regulating it.
