Data from: High resistance towards herbivore-induced habitat change in a high arctic arthropod community
Mammal herbivores may exert strong impacts on plant communities, and are often key drivers of vegetation composition and diversity. We tested whether such mammal-induced changes to a high Arctic plant community are reflected in the structure of other trophic levels. Specifically, we tested whether s...

Mammal herbivores may exert strong impacts on plant communities, and are often key drivers of vegetation composition and diversity.
