(max = 8,947 g m−2), almost all of which were Subarctic forests. Total aboveground biomass tends to be much lower in Arctic tundra than Subarctic forests, where total aboveground biomass averages ~6,000 g m−2but can range from ~2,000 g m−2to ~30,000 g...
Variation in the effects of diverse herbivore assemblages on tundra vegetation communities across the tundra biome has relevant implications for management, emphasizing that there is no one-size-fits-all recommendation. Depending on the ecosystem processes (and hence the ecosystem services) that managers...
