Nutrient deposition on Arctic fox dens creates atypical tundra plant assemblages at the edge of the Arctic

Questions In most ecosystems, some organisms can be considered ecosystem engineers because they modify their physical environment in a way that can affect many other organisms. Nutrient deposition may be extremely important as an ecosystem engineering activity in nutrient‐limited environments, but this mechanism remains understudied. In low‐Arctic tundra, a region characterized by continuous permafrost, low‐nutrient soils, and slow nutrient...
