Ecosystems: Interactions, Energy, and Dynamics
- Ecosystems
Scientists Say: Predator and Prey
Ecological relationships between predators and their prey drive the evolution of plants, animals and microbes.
- Animals
Northern elephant seals snooze only two hours a day at sea
These marine mammals sleep only minutes at a time on months-long trips at sea.
- Animals
Scientists Say: Coral
Over 4,000 species of fish make their home among the reefs created by these colony-dwelling marine animals.
- Plants
Could a plant ever eat a person?
For now, humans aren’t on the menu for carnivorous plants. But what would it take for one to consume a person?
- Environment
Fungi help rescue crops being harmed by microplastics
Microplastics in the soil hinder plant growth. But two finalists at Regeneron ISEF found that fungi and farm waste can reduce the harm.
- Tech
A device spots and counts honeybees hosting a dangerous parasite
At Regeneron ISEF, three teens debuted an infrared system to detect honeybees carrying mites. It can show beekeepers when a colony needs to be treated.
- Environment
Making yards more diverse can reap big environmental benefits
Replacing grass with native plants uses less water and fewer chemicals while providing additional benefits to people and wildlife.
- Ecosystems
Scientists Say: Food web
All the species in an ecosystem and the feeding relationships between them get summed up with this handy picture.
- Health & Medicine
New patch might replace some finger-prick testing of blood sugar
A finalist at Regeneron ISEF created a wearable patch that turns yellow when someone’s blood-sugar level gets high enough to need an insulin shot.
- Animals
People and animals sometimes team up to hunt for food
Dolphins working with people to catch fish recently made a big splash. But humans have a long history of cooperating with other animals.
- Animals
Pokémon ‘evolution’ looks more like metamorphosis
Pokémon “evolve” into larger, more powerful forms within seconds, but this evolution more closely resembles another biological process — metamorphosis.
- Animals
Sleeping glass frogs go into stealth mode by hiding red blood cells
Glass frogs snoozing among leaves blend in by hiding almost all their red blood cells in their liver.
