    Scientists Say: Niche

    An organism’s niche is the role it fills in the community it lives in.

  2. Plants

    Rare-plant hunters race against time to save at-risk species

    One in five plants is at risk of extinction. Meet the rare plant hunters who rappel down cliffs and trek through forests to save them.

  3. Ecosystems

    Mosquito repellent could pose risks to baby salamanders

    Two ingredients in bug repellant — DEET and picaridin — can end up in streams. There, they may hurt salamanders but leave mosquitoes alone, a study finds.

    Welcome to the Arctic’s all-night undersea party

    Life teems in the frozen darkness of the Arctic night. But as the ice recedes and people move in, their light pollution may disturb the animals living there.

    Microplastics take flight in the bellies of mosquitoes

    In polluted water, mosquito larvae may eat microplastic — and it will stay in their bodies as they grow. That might pose risks to skeeter-eating birds.

    Scientists Say: Understory

    A forest isn’t made just out of the tallest trees. Shorter trees and shrubs thrive in their shade. This layer is called the understory.

    Don’t flush your contact lenses

    One in five people who wear contact lenses flush their used eyewear down the sink or toilet. That plastic pollutes the environment and can harm wildlife.

    New tools aim to better predict blooms of toxic algae

    Scientists across the United States are developing programs that can predict when blooms of toxic algal may occur.

    Surprise! Fire can help some forests keep more of their water

    In California’s Sierra Nevada mountains, a century of fire suppression has led to forests with too many trees. But areas thinned by fire now show one benefit: more water.

  10. Animals

    Deep-sea expedition led researchers to doomed octopus nursery

    The ill-fated octopods may be a sign that a healthy population is hiding nearby.

    A robotic fish could help mangroves grow

    Reforested mangroves don’t always grow well. To figure out why, two teens built a robotic mudskipper to measure the mud.

    ‘Boot camp’ teaches rare animals how to go wild

    Animals raised in captivity cannot safely re-enter the wilds without first understanding how to find food and avoid becoming a predator’s lunch. Scientists are helping some species learn this.
