Schwarze Krähenbeere
Allelopathy is characteristic of certain plants, algae, bacteria, coral, and fungi. Allelopathic interactions are an important factor in determining species distribution and abundance within plant communities, and are also thought to be important in the success of many invasive plants. For specific examples, see black walnut ("Juglans nigra)", black crowberry ("Empetrum nigrum"), spotted knapweed ("Centaurea stoebe"), garlic mustard ("Alliaria petiolata"), "Casuarina/Allocasuarina spp.", and nutsedge.
