Still working on your project, eh? Fluther is not an open forum for others to do your homework for you. A small amount of time spent researching will give you the answer to this and other questions about the tundra.
@jeffgoldblumsprivatefacilities Well said.
@lexipoorocks: Start by spelling Arctic correctly. Then you’re all set to Google.
We are not here to do your homework. It is your job so you will learn how to do research and write research papers.
