“…Allelopathy may be another explanation of low cyanobacterial biomass on the studied plant species. Excretion of toxic substances from Chara or Myriophyllum may inhibit the growth of algae, and has been suggested as being responsible for the low density of cyanobacteria (Mulderij et al 2007;Bauer et al 2009). The converse results were presented in the studies of Moeller et al (1988) and Kahlert and Pettersson (2002); these demonstrated that under low nutrient availability, the periphyton communities associated with macrophytes are highly host-specific.…”

Four submerged macrophytes were analysed with their respective assemblages of chironomid and algal taxa. Studies were made bimonthly, from January to November, in a shallow macrophyte-dominated lake. The periphytic algal community was represented by chlorophytes, diatoms and cyanobacteria; diatoms showed the highest relative abundance on the macrophyte species during the study. Algal biomass was affected by the season, and in January the highest values were found on Stratiotes aloides L., Potamogeton lucens L., Myriophyllum spicatum L.; in July on Chara aculeolata Kütz. The lowest algal biomass, on most of the macrophytes studied, was found in September. Larvae of Dicrotendipes sp., Diplocladius cultriger Kieffer, Endochironomus albipennis gr., Endochironomus impar (Walker), Glyptotendipes sp. and Paratanytarsus austriacus Kieffer were dominant within the chironomid community. The spatial distribution of chironomids between macrophytes species was related to periphytic algae biomass and certain environmental variables (temperature, water transparency, biomass of chlorophytes and diatoms). Analysis of chironomid diet and the results of canonical correspondence analysis confirmed this relationship. The strongest chironomid-algae relationships were observed on S. aloides and P. lucens.

“…The differential impact of allelopathy versus competition for light for the macrophytes Chara spp. and Stratiotes aloides has been modelled recently (Mulderij, Van Nes, & Van Donk, 2007). Further in situ studies and modelling may help determining the relative contribution of each individual strategy including allelopathy to the successful survival of certain macrophyte species under eutrophic conditions.…”

Inhibition of phytoplankton by allelochemicals released by submerged macrophytes is supposed to be one of the mechanisms that contribute to the stabilisation of clear-water states in shallow lakes. The relevance of this process at ecosystem level, however, is debated because in situ evidence is difficult to achieve. Our literature review indicates that allelopathically active species such as Myriophyllum, Ceratophyllum, Elodea and Najas or certain charophytes are among the most frequent submerged macrophytes in temperate shallow lakes. The most common experimental approach for allelopathic interference between macrophytes and phytoplankton has been the use of plant extracts or purified plant compounds. Final evidence, however, requires combination with more realistic in situ experiments. Such investigations have successfully been performed with selected species. In situ allelopathic activity is also influenced by the fact that phytoplankton species exhibit differential sensitivity against allelochemicals both between and within major taxonomic groups such as diatoms, cyanobacteria and chlorophytes. In general, epiphytic species apparently are less sensitive towards allelochemicals than phytoplankton despite living closely attached to the plants and being of key importance for macrophyte growth due to their shading. Light and nutrient availability potentially influence the sensitivity of target algae and cyanobacteria. Whether or not additional stressors such as nutrient limitation enhance or dampen allelopathic interactions still has to be clarified. We strongly propose allelopathy as an important mechanism in the interaction between submerged macrophytes and phytoplankton in shallow lakes based on the frequent occurrence of active species and the knowledge of potential target species. The role of allelopathy interfering with epiphyton development is less well understood. Including further levels of complexity, such as nutrient interference, grazing and climate, will extend this ecosystem-based view of in situ allelopathy. ZusammenfassungDie Inhibition von Phytoplankton durch Allelochemikalien aus submersen Makrophyten ist einer der potentiellen Mechanismen, die zur Stabilisierung von Klarwasserzusta¨nden in Makrophyten-dominierten Flachseen beitragen. Die Relevanz dieses Prozesses auf Ö kosystemebene ist jedoch umstritten, da der in situ Nachweis schwierig ist. Unsere Literaturu¨bersicht zeigt, dass allelopathisch aktive Arten wie Myriophyllum, Ceratophyllum, Elodea und Najas sowie bestimmte Characeen zu den ha¨ufigsten submersen Makrophyten in Flachseen der gema¨ßigten Breiten geho¨ren. Der experimentelle Nachweis allelopathischer Effekte auf Phytoplankton erfolgte bisher u¨berwiegend durch Pflanzenextrakte oder aufgereinigte Substanzen. Ein endgu¨ltiger Beweis erfordert jedoch zusa¨tzlich Experimente unter in situ Bedingungen, publ. in: Basic and Applied Ecology, 9, 2008, pp. 422-432 Konstanzer

“…Submerged plants can stabilize sediments (Scheffer 1998;Horppila & Nurminen 2003;, remove suspended particles from the water by reducing wave turbulence (Vermaat et al 2000;Horppila & Nurminen 2003), provide a substrate for epiphytic algae that sequesters nutrients from the water (Blumenshine et al 1997;McCormick et al 2001;Toet et al 2003), reduce P fluxes into the water column from sediment (Wigand et al 1997;Horppila & Nurminen 2003;Qin et al 2007), and inhibit phytoplankton growth (Mulderij et al 2007). Thus, areas of dense submerged plants in shallow lakes typically have very clear water and low concentrations of nutrients as well as phytoplankton (Jeppesen et al 1998;Blindow et al 2002).…”

It is common for submerged plants to become less abundant and disappear in eutrophic lakes in the world. To explore degradation mechanisms of submerged plants during the growing season, we determined chlorophyll and malondialdehyde (MDA) concentrations in Vallisneria natans (Lour.) Hara cultivated under four different nutrient concentrations (N/P, mg/L): T1 D 0.5/0.05, T2 D 2.5/0.25, T3 D 4.5/0.45, and T4 D 12.5/1.25) and under low and high density of epiphytic algae. With the increase in nutrients, the content of chlorophyll in the leaves of V. natans varied in the order T3 > T2 > T1 (T4) at low density (grazed) of epiphytic algae and varied in the order T3 > T2 > T1 > T4 in the high density (ungrazed) of epiphytic algae. With the increase in nutrients, the content of MDA in the leaves of V. natans varied in the order T4 >T1 (T2, T3) at the low density (grazed) of epiphytic algae and varied as T4 > T3 > T2 > T1 at the high density of epiphytic algae. At the same time, chlorophyll content of V. natans was significantly higher (p < 0.01 and the content of MDA was significantly lower (p < 0.01) in the grazed treatment than in the non-grazed treatment under the same nutrient concentrations. During the growing season, total nitrogen and total phosphorus concentrations were low (N < 4.5 mg N/L, P < 0.45 mg P/L) in Lake Taihu, a large shallow eutrophic lake in China; consequently water column nutrient loading benefited the growth of V. natans, but the high biomass of epiphytic algae and planktonic algae caused by the high nutrient loading of water column inhibited the growth of V. natans.
