Ecosystems: Interactions, Energy, and Dynamics
- 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.
- Animals
Let’s learn about whales and dolphins
Whales, dolphins and porpoises are all cetaceans — mammals that live in water and have a streamlined body similar to a fish.
- Health & Medicine
Will we all need COVID-19 booster shots?
Experts say not yet, but booster vaccines may be coming as new SARS-CoV-2 virus variants keep emerging.
- Climate
‘Tree farts’ make up about a fifth of greenhouse gases from ghost forests
Heat-trapping gases from dead trees play an important role in the environmental impact of “ghost” forests.
- Animals
Common parasite may help mussels survive heat waves
By whitening shells, the organism helps the shellfish stay cool on sunny days, a new study suggests.
- Animals
Most species of beetles pee differently than other insects
Scientists uncover their unique system for balancing ions and water. The findings may hint at why beetles are the most diverse animals on Earth.
- Environment
Pond scum can release a paralyzing pollutant into the air
New study finds blooms of blue-green algae can seed the air with a poisonous pollutant.
- Animals
A common antibiotic might save some sick corals
The antibiotic amoxicillin stopped tissue death in corals for at least 11 months after treatment.
