Muskox grazing can drive large changes in vegetation in the long term, but these changes do not seem to influence the composition of arthropod communities nor the structure of their predator –prey interactions. This surprising result implies that high Arctic arthropod communities might be highly resistant to changes in their habitat, possibly due to the high connectance of their food webs.
