Further improvements in water quality of the Dutch Borderlakes: two types of clear states at different nutrient levels

Toxic cyanobacteria and cyanotoxins in European waters – recent progress achieved through the CYANOCOST Action and challenges for further research

“…for Microcystis (Bowling and Baker, 1996;Ibelings et al, 1998;Verspagen et al, 2006) and Dolichospermum (Webster et al, 2000;Mitrovic et al, 2011). Biomanipulation can be successful in lakes where the external and internal loading have been reduced as it can promote the development of submerged macrophytes and help to move from a turbid state to a clear water state (Noordhuis et al, 2016;Triest et al, 2016). This holds true for water-level management (Bakker and Hilt, 2016).…”

Phosphorus Availability and Growth of Benthic Primary Producers in Littoral Lake Sediments: Are Differences Linked to Induced Bank Filtration?

“…This process has been described as being fast [18,19] and might result in a loading of the upper sediment layers with P. A similar accumulation of P in littoral areas has been described for invasive dreissenid mussels, which filter pelagic water and excrete P-rich faeces in benthic areas [35]. Dreissenid mussels, however, can filtrate the entire lake volume during one day [24,36], while bank filtration in Lake Müggelsee takes about a year for pumping the lake volume. More detailed biogeochemical analyses of the upper layers of sediments affected by bank filtration accompanied by experimental manipulations of the bank filtration intensity are needed to provide evidence for a causal relationship between bank filtration, P availability and binding forms in littoral lake sediments.…”

Novel ecosystems in urbanized areas under multiple stressors: Using ecological history to detect and understand ecological processes of an engineered ecosystem (lake Markermeer)

“…Experiences from neighboring shallow lakes illustrate how turbid water can block the development of benthic flora and fauna. Here, an increase of transparency was followed by an increased plant growth and abundances of zebra mussels (Noordhuis et al 2016). During the 1980s visibility had improved artificially in these lakes after removal of bream, but this clear water period did not lead to ecological recovery of those lakes.…”
