“…TP concentrations were on average above 0.1 mg.L x1 (Appendix 2 available online at www.limnology-journal.org). Dissolved inorganic nitrogen concentrations varied a lot from pond to pond and, although mostly substantially lower than in some other European ponds and small lakes (Cottenie et al, 2001;Irfanullah and Moss, 2005;Moss et al, 2005;Søndergaard et al, 2005), they generally exceeded the level at which phytoplankton growth could be slowed down due to nitrogen limitation (Appendix 2; Reynolds, 2006). High productivity potential was realised in some ponds in the development of conspicuous phytoplankton blooms often dominated by bloom-forming cyanobacteria.…”

-Blooms of toxic cyanobacteria became a common feature of temperate lakes and ponds owing to human induced eutrophication. Occurrence of cyanobacterial blooms in an urban context may pose serious health concerns. This necessitates the development of tools for assessment of the risk of noxious bloom occurrence. A five year study of 42 Brussels ponds showed that cyanobacteria have threshold rather than linear relationships with environmental variables controlling them. Hence, linear relationships have limited predictive capacity for cyanobacterial blooms. A probabilistic approach to prediction of bloom occurrence using environmental thresholds as conditions in conditional probability calculation proved to be more useful. It permitted the risk of cyanobacterial bloom occurrence to be quantified and thus the conditions and thence the ponds the most prone to cyanobacterial bloom development to be singled out. This approach can be applied for the assessment of the risk of cyanobacterial bloom occurrence in urban ponds and thus can facilitate monitoring planning, remediation efforts and setting restoration priorities.

“…The presence/absence of the vegetation was verified with a rake when water was not sufficiently transparent. Because submerged macrophytes were often associated with filamentous green algae, which are also known to inhibit phytoplankton growth (Irfanullah and Moss 2005;Peretyatko et al 2007a), their combined surface cover was used in statistical analyses.…”

“…Increased productivity has caused considerable degradation of ecological water quality often resulting in the development of potentially toxic cyanobacterial blooms (Paerl 1988;Willame et al 2005;Hudnell 2008) or profuse growth of filamentous green algae (Irfanullah and Moss 2005).…”

Phytoplankton, zooplankton, submerged vegetation and main nutrients have been monitored in 48 eutrophic ponds from the Brussels Capital Region (Belgium) between 2005 and 2008. Nine ponds have been biomanipulated in order to improve their ecological quality and prevent the occurrence of noxious cyanobacterial blooms. The 4-year study of a large number of ponds allowed identification of the factors having the strongest influence on phytoplankton growth. Continuous monitoring of the biomanipulated ponds allowed the significance of changes caused by biomanipulation to be tested as well as the main reasons of biomanipulation successes and failures to be elucidated. The main factors controlling phytoplankton in the ponds studied appeared to be grazing by large cladocerans and inhibition of phytoplankton growth by submerged vegetation. Biomanipulation resulted in a significant decrease in phytoplankton biomass in general and biomass of bloom-forming cyanobacteria in particular that were associated with a significant increase in large Cladocera density and size. In six out of nine ponds biomanipulation resulted in the restoration of submerged vegetation. The maintenance of the restored clearwater state in the biomanipulated ponds was strongly dependent on fish recolonisation and nutrient level. In the absence of fish, the clearwater state could be maintained by submerged vegetation or large zooplankton grazing alone. In case of fish recolonisation, restoration of extensive submerged vegetation could buffer, to a considerable degree, the effect of fish except for ponds with high nutrient levels.

“…On the other hand, much research has been devoted to the conditions under which these mats form (Wetzel 1996;Zohary et al 1998;Berry and Lembi 2000), their function in ecosystems (Hillebrand 1983;Usher and Blinn 1990;Falkowski and Raven 2007), and their role in the stabilization and prevention of sediment resuspension, and the cycling of phosphorus, nitrogen and carbon (Ozimek 1990;Goldsborough and Robinson 1996;McDougal et al 1997;Scheffer 2001;Frost and Elser 2002;Widdows et al 2004;Irfanullah and Moss 2005). Given the conditions that facilitate formation of algal mats, it is reasonable to assume that floating algal rafts played an important role in the early development of many lake ecosystems.…”

“…In general, however, the formation of algal and cyanobacterial mats is determined primarily by periodic changes in trophic state (Rosenberg et al 1990;Wetzel1996). Competition between macrophytes and microalgae for nutrients and light (Ozimek 1990;Scheffer 2001;Irfanullah and Moss 2005) means that shallow-water reservoirs and the littoral areas of large lakes with sediments only sparsely covered by macrophytes, are particularly suited for the formation of algal mats. The ecological preferences of algal species that dominate mats may cause proliferation to occur in reservoirs at different times.…”

Algal mats transport diaspores and carpological remains in shallow lakes

Algal mats in lakes and reservoirs can transport diaspores and carpological remains of plants, and thus may influence the creation of taphocoenoses. In 2012, I quantified carpological remains in two types of algal mats from a small reservoir in southern Poland. Mats formed by filamentous algae participate primarily in the original transport of diaspores, and can influence their concentration and facilitate their migration, mainly between the shores of the reservoir. Diatom mats partake primarily in diaspore redeposition, but can also cause their dispersal between the shore zone and the central part of the reservoir. This research demonstrates that mats built by diatoms contain far more remains and are more biologically diverse than filamentous algal mats. Movement of carpological remains observed in both types of algal mats points to their role in the formation of taphocoenoses and suggests that algal mats must be considered when interpreting macrofossil records.
