“…Allelopathic interactions apparently are enhanced under abiotic or biotic Stress (Lovett et al, 1989;Tang et al, 1995;Reigosa et al, 1999). This is corroborated by many studies showing the impact of nutrient limitation of both donor and target organisms on the outcome of allelopathic interactions (see Section V1.A).…”

“…Unfortunately, we are lacking studies directly addressing this aspect. It would be interesting to see if Reigosa's hypothesis (Reigosa et al, 1999) is also generally applicable for aquatic ecosystems. More insight could arise from a comparison of the allelopathical potential of aquatic neophytes and their native relatives.…”

“…The use of cultured algae or cyanobacteria in aquatic allelopathy is frequent because they allow bioassays to be run under controlled and replicated conditions. Reigosa et al (1999) argued that organisms within one habitat should be adapted to allelochemicals in this system. Therefore, allelopathic interactions should only be expected between organisms from different habitats.…”

“…Allelochemicals can interfere with many processes of target organisms (see, e.g., Reigosa et al, 1999;Einhellig, 2001). From the above-mentioned studies it is apparent that allelopathically active compounds are often directed at two physiological processes, photosynthesis and enzyme activity.…”

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.

This usually describes plant-plant interactions, as its original description by Molisch (1937) suggests: 'The influence of one plant on another'. Given the prevalence and detriment of weeds (Oerke, 2005), and the burgeoning development of populations with resistance to multiple synthetic herbicides (Powles & Yu, 2010), allelopathy may be a valuable alternative to traditional chemical control (Macias et al., 2007), in various forms of delivery, including the deployment of

Plant–plant interactions are among the fundamental processes that shape structure and functioning of arid and semi‐arid plant communities. Despite the large amount of studies that have assessed the relationship between plant–plant interactions (i.e., facilitation and competition) and diversity, often researchers forget a third kind of interaction, known as allelopathy. We examined the effect of plant–plant interactions of three dominant species: the perennial grass Lygeum spartum, the allelopathic dwarf shrub Artemisia herba‐alba, and the nurse shrub Salsola vermiculata, on plant diversity and species composition in a semi‐arid ecosystem in NE Spain. Specifically, we quantified the interaction outcome (IO) based on species co‐occurrence, we analyzed diversity by calculation of the individual species–area relationship (ISAR), and compositional changes by calculation of the Chao‐Jaccard similarity index. We found that S. vermiculata had more positive IO values than L. spartum, and A. herba‐alba had values between them. Lygeum spartum and A. herba‐alba acted as diversity repellers, whereas S. vermiculata acted as a diversity accumulator. As aridity increased, A. herba‐alba transitioned from diversity repeller to neutral and S. vermiculata transitioned from neutral to diversity accumulator, while L. spartum remained as diversity repeller. Artemisia herba‐alba had more perennial grass species in its local neighborhood than expected by the null model, suggesting some tolerance of this group to its “chemical neighbor”. Consequently, species that coexist with A. herba‐alba were very similar among different A. herba‐alba individuals. Our findings highlight the role of the nurse shrub S. vermiculata as ecosystem engineer, creating and maintaining patches of diversity, as well as the complex mechanism that an allelopathic plant may have on diversity and species assemblage. Further research is needed to determine the relative importance of allelopathy and competition in the overall interference of allelopathic plants.
