Allelopathy of aquatic autotrophs
Magazine article from: Critical Reviews in Plant Sciences; 1/1/2003; ; 700+ words
; ABSTRACT: Allelopathy in aquatic environments may provide a competitive advantage to angiosperme, algae, or cyanobacteria in their interaction with other primary producers. Allelopathy can influence the competition between different photoautotrophs for resources and change the succession of
