Interfering with neighbouring communities: Allelopathy astray in the tundra delays seedling development
Abstract Altered species composition caused by environmental and climatic change can affect the transfer of plant residues among communities. Whereas transferred residues are typically considered a resource in recipient systems, residues of allelopathic species may instead cause interference. Evergr...
