“…Effective defensive traits may include fast apical growth, canopy formation and the release of allelopathically active compounds. Evidence from field studies shows that allelopathy may be involved in macrophyte-microphyte interactions (Phillips et al, 1978;Scheffer et al, 1993). However, in situ no direct proof has been possible so far.…”

“…Allelopathic interaction should be an efficient counteractive strategy for many of them. Sudden switches between phytoplankton or macrophyte dominance in many shallow eutrophic lakes occur frequently (Scheffer et al, 1993;Jeppesen et al, 1998). These changes are influenced by many abiotic and biotic factors, among them allelopathic interference of macrophytes with phytoplankton development (Crawford, 1977;Phillips et al, 1978;Gross, 1999;Scheffer, 1999).…”

Allelopathy in aquatic environments may provide a competitive advantage to angiosperms, 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 species, for exarnple, in phytoplankton cornmunities. Field evidence and laboratory studies indicate that allelopathy occurs in all aquatic habitats (marine and freshwater), and that ail prirnary producing organisms (cyanobacteria, micro-and macroalgae as well as angiospenns) are capable of producing and releasing allelopathically active compounds. Although allelopathy also includes positive (stimulating) interactions, the majority of studies describe the inhibitory activity of ailelopathicaily active compounds. Different mechanisms operate depending on whether allelopathy takes place in the Open water (pelagic zone) or is Substrate associated (benthic habitats). Allelopathical interactions are especiaily common in fully aquatic species, such as submersed macrophytes or benthic algae and cyanobacteria. The prevention of shading by epiphytic and planktonic primary producers and the competition for space may be the ultimate cause for allelopathical interactions. Aquatic ailelochemicals often target multiple physiological processes. The inhibition of photosynthesis of competing primary producers seems tobe a frequent mode of action. Multiple biotic and abiotic factors determine the strength of allelopathic interactions. Bacteria associated with the donor or target organism can metabolize excreted aiielochemicals. Frequently, the impact of surplus or limiting nutrients has been shown to affect the overail production of allelochemicals and their effect on target species. Similarities and differences of ailelopathic interactions in marine and freshwater habitats as well as between the different types of producing organisms are discussed.

“…Decline of submersed macrophytes has occurred in many eutrophic lakes worldwide, due to direct and indirect effects of nitrogen (N) and phosphorus (P) overloading in the waters (Scheffer et al 1993). As high ammonium (NH 4 + ) concentrations are toxic to both animals and higher plants, this has been repeatedly reported as a causal factor for the decline of submersed macrophytes in eutrophic lakes, where NH 4 + -N concen trations in the water column can reach 10 mg l −1 and surpass the NH 4 + tolerance thresholds for many submersed macrophytes (van Katwijk et al 1997, Cao et al 2007).…”
