Ecosystems: Interactions, Energy, and Dynamics
- Animals
Even raised by people, wolves don’t tune into you like your dog
Dog puppies outpace wolf pups at engaging with humans, even with less exposure to people, supporting the idea that domestication changed dogs’ brains.
- Animals
Uncovering secrets of the glasswing butterfly’s see-through wings
The tricks of its transparency include sparse, spindly scales and a waxy coated membrane.
- Earth
Let’s learn about Antarctica
This continent is dry, windy and very cold — and home to penguins, ice and a lot of scientific research.
- Animals
Some beetles walk along the underside of the water’s surface
Their upside-down scurrying is a rare method of getting around.
- Animals
Dinosaur families appear to have lived in the Arctic year-round
Fossils of baby dinosaurs in northern Alaska challenge the idea that northern dinosaurs only spent their summers in the high Arctic.
- Animals
Spiders can take down and feast on surprisingly big snakes
Snared in sticky webs and subdued by poison, even venomous snakes can become a spider’s soup.
- Climate
‘Zombie’ wildfires can reemerge after wintering underground
Climate change may make these not-quite-dead blazes more common. Scientists are learning to predict where a zombie might emerge.
- Life
Let’s learn about microbes
There may be a billion species of microorganisms on Earth — but scientists have only discovered a small fraction of them.
- Animals
A bubble of air lets some lizards breathe underwater
Anolis lizards leap into streams to escape danger. Now researchers have figured out how they can stay underwater for up to a quarter of an hour.
- Animals
Sudden shark die-off 19 million years ago eliminated most species
New fossil evidence shows 90 percent of sharks died in the mysterious event.
- Plants
These ferns may be first plants known to work together as ants do
Staghorn ferns grow in massive colonies where individual plants contribute different jobs. This may make them “eusocial,” like ants or termites.
- Animals
Urchin mobs can literally dis-arm a predator
Urchins are important herbivores — but not strict vegetarians. When hungry enough, they may even rip apart their predators for lunch.
