Red foxes enhance long‐term tree growth near the Arctic treeline
Abstract Recent climate warming is expected to increase tree growth and productivity, substantially altering ecological function and boundaries in northern ecosystems. Although climate largely determines the range and growth of trees in any biome, variations in microsite conditions can influence gro...
