Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.

Dogs and other animals could aid the spread of monkeypox
Now that monkeypox has spread to a dog, researchers fear other species could help the virus become widespread outside of Africa for the first time.

Sleepy mosquitoes prefer dozing over dining
Mosquitoes repeatedly shaken to prevent slumber lagged behind well-rested ones when offered a leg to feed on.
- Animals
Some Greenland polar bears are surviving with very little sea ice
The ‘glacial mélange’ on which they’ve come to rely — a mix of ice, snow and slush — could be a temporary refuge for some polar bears.
- Animals
Palm-size marsupials may face extinction from wild ‘house’ cats
After surviving Australian bushfires, the Kangaroo Island dunnart is losing ground as it's targeted by hungry predators.
- Environment
Night lights make even the seas bright
Light from coastal cities and offshore development may shine deep enough to disrupt tiny critters living dozens of meters (yards) below the surface.
- Chemistry
Ponds made to control floods can spew climate-warming gases, study finds
Younger stormwater ponds can release more carbon in gases than they absorb, a study finds. That could aggravate global warming.
- Animals
Orcas can take down the largest animal on the planet
For the first time, scientists observed that orcas can kill blue whales by using the same hunting techniques that have worked on other large whales.
- Animals
Bees and butterflies struggle to find flowers in polluted air
Emissions from cars and trucks make it harder for insects to find flowers. That in turn reduces flower visits and pollination, a new study finds.
- Ecosystems
Recycling a climate-warming gas could make ‘greener’ farmed fish
Instead of warming the climate, methane gas can be collected to help farmers. Along the way, it may also save some fish.
- Life
In blazing heat, some plants open leaf pores — and risk death
When heat waves and droughts collide, water is precious. Some thirsty plants try to cool off by opening tiny pores — only to lose water even faster.
- Animals
Rewilding returns lost species to strengthen ecosystems
Restoring the missing species can help undo human-caused problems by aiding forests, slowing climate change and reducing wildfires.

Scientists Say: Savanna
Savannas exist where there is more rainfall than in a desert, but less than in a forest.
