Caribou and muskoxen significantly affect Arctic plant growth, revealing their overlooked role in climate impacts.

We identify biomes by the vegetation and animals that populate them and determine the location of each by the regional ...

The story of Arctic greening has overlooked some main characters. At center stage are climate change and warming temperatures ...

A new study highlights the importance of caribou and muskoxen to the greening Arctic tundra, linking grazing with plant phenology and abundance in the Arctic tundra.

The study, published today in the journal PNAS Nexus, highlights the importance of large herbivores to the Arctic ecosystem, linking grazing with plant phenology and abundance in the Arctic tundra.

But how has the environment shaped the landscape and this biome? The climate in the tundra biomes is extremely cold - I mean seriously cold! You wouldn’t want to forget your winter woollies.

After three decades, I had returned north with a purpose: to assess how tundra plants were responding in a rapidly changing climate. For my assistants and me, the plan was straightforward.
