“…Thus, an alternative predator avoidance strategy of die1 horizontal migration (DHM) is commonly observed in shallow lakes, where prey migrate into the vegetated littoral zone during the day ( Burks et al 2002). The structural complexity of the vegetation can act as a favorable refuge by reducing the feeding rate of predatory fish (Diehl 1988, Jeppesen et al 1998.…”

Diel horizontal migration (DHM) by small perch (PercaJ2~iatili.s) between the littoral vegetation zone and open water was studied in the eutrophic Kirkkojtirvi basin (southern Finland). Small perch showed reversed DHM by occupying the open water area during daylight and moving into the littoral zone at dusk. They avoided the vegetation zone during daylight because water clarity among the plants was much higher than in the open water, which was attributed to the reductive effect of macrophytes on sediment resuspension. The migration of perch into the littoral zone at dusk was explained by the higher availability of zooplankton among the plants. The results indicated that the importance of structural complexity of vegetation as a rehge decreases with increasing turbidity of the water. The effects of macrophytes on water turbidity may create circumstances where predation threat for small planktivorous fish during daylight is highest among the vegetation, and such circumstances may thus induce reversed DHM.

“…Recent restoration measures, where external phosphorus (P) input and water turbidity were experimentally reduced, have led to the return of dense charophyte beds (Van den Berg et al, 1998a;Meijer et al, 1999;Ibelings et al, 2007). These restoration measures, however, were performed in sandy lakes, whereas peaty lakes are suffering from high internal loading of P from the sediment and are more prone to sediment resuspension (Cooke et al, 1993;Jeppesen et al, 1998;Søndergaard et al, 2003). Under natural conditions, peaty lakes in the Netherlands would not suffer from internal P loading, as upwelling iron rich groundwater binds to phosphorus (in the form of phosphate, PO 4 ) in the sediment.…”

Iron addition as a shallow lake restoration measure: impacts on charophyte growth

et al. 2012

Eutrophication has caused a decline of charophyte species in many shallow lakes in Europe. Even though external inputs of phosphorus are declining, internal loading of P from the sediment seems to delay the recovery of these systems. Iron is a useful chemical binding agent to combat internal phosphorus loading. However, the effects of iron addition on charophytes are not yet known. In this study we experimentally tested the potential toxicity of iron(III)chloride (FeCl 3 ) on two different charophytes, Chara virgata Kützing and Chara globularis Thuiller added at the concentration of 20 g Fe m -2 and 40 g Fe m -2 to the surface water. C. virgata growth was not significantly affected, whereas C. globularis growth significantly decreased with increasing iron concentrations. Nonetheless, biomass of both species increased in all treatments relative to starting conditions. The decrease of C. globularis biomass with high iron additions may have been caused by a drop in pH and alkalinity in combination with iron induced light limitation. Iron addition over a longer time scale, however, will not cause this rapid drop in pH. Therefore, we conclude that adding iron(III)chloride in these amounts to the surface water of a lake can potentially be a useful restoration method.
