True stories

When wolves returned to Yellowstone in 1995, they rewrote an entire food chain.

Yellowstone, USA

When wolves returned to Yellowstone in 1995, they rewrote an entire food chain. For about seventy years the park had none, and elk had multiplied until they stripped young willows and aspen to stubble along the rivers. Then thirty-one wolves, brought from Canada across two winters, changed everything. As the predators thinned and moved the elk herds, streamside trees finally grew tall again. Songbirds returned to the branches, and beavers, which had dwindled to a single colony, came back to build dams that cooled the water for fish. Scientists call this a trophic cascade: one animal at the top reshaping plants, rivers and wildlife far below it.

At an aquarium in California, orphaned sea otter pups are raised by adoptive otter mothers, and the ripples reach an entire estuary.

Monterey, USA

At an aquarium in California, orphaned sea otter pups are raised by adoptive otter mothers, and the ripples reach an entire estuary. When a stranded pup arrives, staff pair it with a resident female who teaches it to dive, forage and groom, while human carers stay hidden so the pup never bonds with people. Grown up, many are released into nearby Elkhorn Slough. There they hunt crabs, which lets tiny sea slugs multiply and scrub algae from the eelgrass. The eelgrass has since spread again, steadying the shoreline and cleaning the water. One act of animal kindness, it turns out, can heal a whole food web.

Did you know?

producer: Deep-sea microbes can make food using chemicals instead of sunlight, starting food chains where no sunbeam ever reaches.
consumer: A Venus flytrap usually needs two touches close together to shut, turning a plant's insect-catching leaf into a simple counting device.
predator: Some predators hunt without seeing their prey: snakes can detect heat, while sharks sense faint electrical signals.
prey: An opossum's playing dead is an automatic response to danger, making its acting trick a bodily reaction rather than a planned performance.
herbivore: Hippos usually count as herbivores, yet researchers have seen them eat meat, making a grass-eater's menu less fixed than its label suggests.
carnivore: A carnivorous pitcher plant traps animals in a liquid-filled leaf, showing that eating prey isn't a habit limited to animals.
omnivore: A giant panda's savory-taste receptor gene is inactive, giving a bamboo-eating bear a genetic difference from its usually omnivorous relatives.
decomposer: Trees growing on fallen logs can stand on root stilts when decomposers remove the wood, leaving an empty space beneath the trunk.
energy: Some hummingbirds' body temperatures fall almost to freezing during nighttime mini-hibernation, saving energy before the birds warm up again at dawn.
sunlight: Some ocean animals keep algae inside their tissues, letting partners turn sunlight into food while the host provides a home.
plankton: Some plankton move up and down each day, turning tiny creatures into participants in one of Earth's largest migrations.
nutrient: Salmon carry ocean nutrients into forests, where researchers detect their nitrogen in trees, linking woodland growth with fish arriving from the sea.
habitat: A whale carcass can become a deep-sea habitat, supporting communities that feed on the remains long after the animal has sunk.
ecosystem: Island rats can harm nearby coral reefs indirectly, by reducing seabirds whose droppings supply nutrients that eventually reach the surrounding sea.

When we try to pick out anything by itself, we find it hitched to everything else in the Universe.
