Warming global climate is changing the vegetation structure of forests in the far north. It's a trend that will continue at least through the end of this century, according to NASA researchers.

Mountain goats, sheep, marmots, and birds live in mountain—or alpine—tundra and feed on the low-lying plants and insects. Hardy flora like cushion plants survive in the mountain zones by ...

We identify biomes by the vegetation and animals that populate them and determine the location of each by the regional climate. The tundra biome is characterized by extremely cold temperatures and ...

The unique vegetation of the Arctic tundra could disappear by the year 2050 if no substantial reduction in global warming is achieved, scientists have warned. Experts at the Alfred Wegener ...

A common plant of the tundra biome, cotton grass is a herbaceous perennial with slender skinny leaves that look like grass. The stems grow anywhere from eight to 28 inches tall with three to five ...

But the tundra was very dry in 2007 and fire-fueling winds kicked up the blaze. During this single event, the immediate combustion of plants and soils and the thawing of frozen soils injected an ...

Ecologist Isla Myers-Smith researches how tundra plants respond to climate change and what it means for future ecosystems. While she's mostly worked in the Canadian Arctic, for the last two years ...

This shift is partly due to giant polar wildfires burning down tundra vegetation and all the carbon it's stored. It's also ...

Now scientists can add the Arctic tundra to that list. In most ecosystems, plants absorb carbon dioxide from the atmosphere. Those plants grow, die, or get eaten by animals that also grow and die.

Yes, even the mostly treeless tundra can have vibrant fall foliage ... production of a special compound called anthocyanin that plants need to bring nutrients up through their roots.
