“…The controversy over P limitation comes, in part, from difficulties in separating direct P limitation from alternative mechanisms for the poor quality of P-deficient algae, including fatty acid deficiencies (Müller-Navarra 1995) and digestion resistance (Van Donk and Hessen 1993;Van Donk et al 1997). Cyanobacteria, for example, can be a poor quality food for a variety of reasons, including toxicity, digestion resistance, difficulties in handling and ingesting filaments and colonies, and nutritional inadequacy (reviews by Lampert 1987;de Bernardi and Giussani 1990;Christoffersen 1996).…”

“…In March of that year, about two-thirds of the fish stock of Lake Breukeleveen were removed by netting in an attempt to increase the abundance of Daphnia and thereby improve water clarity (Van Donk et al 1990). The lake was also stocked with fingerlings of a piscivorous fish (pike, Esox lucius) and with large-bodied Daphnia (Daphnia pulex and Daphnia hyalina).…”

“…Poor food quality can prevent trophic cascades from zooplankton to phytoplankton even when predation rates are low (e.g., Elser et al 1998;MacKay and Elser 1998). Van Donk et al (1990) speculated that the failure of their food chain manipulation to improve water clarity in Lake Breukeleveen was due to poor food quality for the zooplankton grazers. Drawing on laboratory experiments, Davidowicz et al (1988) cited the high abundance of filamentous cyanobacteria as the probable cause of poor Daphnia growth in seston from Lake Loosdrecht.…”

The Loosdrecht lakes comprise three shallow, interconnected hypereutrophic lakes in The Netherlands. A lake restoration project conducted during the 1980s resulted in reduced phosphorus loading. However, no changes in phytoplankton abundance or species composition were noted, although seston carbon:phosphorus (C:P) ratios increased. Filamentous cyanobacteria and detritus continued to dominate the seston. Moreover, planktivorous fish were very abundant. Relationships between zooplankton abundance and seston abundance and stoichiometry (C:P and carbon:nitrogen ratios) were analyzed using data collected during 9 yr of intensive study of the three lakes. Analysis based on annual means shows surprisingly strong and consistent inverse relationships between Daphnia abundance and the seston C:P ratio for two of the three lakes. In these two lakes (Loosdrecht and Vuntus Lakes), the annual mean abundance of Daphnia cucullata ranged from 104 to 0.7 individuals L−1 over a range in mean seston C:P ratios from about 250 to 500 (molar). In the third lake, Breukeleveen, Daphnia abundance was higher for a given seston C:P ratio, especially during the 2 yr following a biomanipulation project in this lake. Analysis of seston C:P ratios and Daphnia abundance in individual samples provides further evidence that high seston C:P ratios constrained Daphnia abundance in all three lakes. In contrast to Daphnia, the abundances of zooplankters with low P requirements, including Bosmina spp. and cyclopoid copepods, show little relationship to seston C:P ratios. These results suggests that the abundance of Daphnia in the Loosdrecht lakes was determined by the variable P content of their diets and consistently strong fish predation.

“…This may be because of high predation pressure by fish Van Donk et al, 1994), or unsuitability of the phytoplankton dominated by filamentous cyanobacteria (Blindow et al, 2000;DeMott et al, 2001a, b). The latter could be one reason why Daphnia does not develop in peaty lakes after biomanipulation (Van Donk et al, 1990;Lammens et al, 1992).…”

“…Unsuccessful lake biomanipulation is often explained by wind induced resuspension (Van Donk et al, 1990;Van Der Vlugt et al, 1992), and biomanipulation in peaty lakes, with their loose bottom sediments, might not work due to wind resuspension (Van Liere & Gulati, 1992;Van Liere & Janse, 1992;Scheffer, 2001;Gulati & Van Donk, 2002). In none of these studies, however, the role of wind resuspension and its interaction with fish stock removal was quantified.…”

The effects of fish stock reduction (biomanipulation) was studied in an 85 ha shallow peaty turbid lake. The lake cleared in a 4-week period in April-May 2004, which demonstrated that biomanipulation can be effective in peaty lakes. We demonstrated that it is possible to reduce the fish stock to <25 kg ha -1 benthivorous fish and <15 kg ha -1 planktivorous fish, sufficiently low to switch the lake from a turbid to a clear state. Knowledge of lake morphology, fish stock, fish behaviour, and a variety of fishing methods was necessary to achieve this goal. It is expected that continuation of fisheries to remove young of the year planktivorous species is needed for several years, until macrophytes provide sufficient cover for zooplankton and can compete with phytoplankton. Cladocerans developed strongly after fish removal. The clearing of the lake coincided with a sudden decrease of filamentous cyanobacteria and suspended detritus, and a strong increase of Bosmina. We assume that Bosmina was able to reduce filamentous prokaryotes and detritus. After the disappearance of the cyanobacteria, Bosmina disappeared too. After the clearing of the lake Daphnia dominated in zooplankton and apparently was able to keep phytoplankton levels low. In our case, wind resuspension did not prevent biomanipulation from being successful. No correlation between windspeed and turbidity was found, neither in an 85 ha nor in a 230 ha shallow peaty lake. Regression analysis showed that on average 50% of the amount of suspended detritus can be explained by resuspension by fish and 50% by phytoplankton decomposition. The main goal of this biomanipulation experiment, clear water and increased submerged plant cover in a shallow peaty lake, was reached.

Linking population dynamics models with empirically derived models through phytoplankton primary production

There are alternative methods for estimation of phytoplankton primary production (PP) that are fundamentally different in the calculation approach. The processoriented PP model is a mechanistic, empirically derived method based on the photosynthesis-light relationships. The population dynamics-based PP calculation, which is a synthetic method, provides a production estimate based on population dynamics of phytoplankton. These alternative methods were here compared with regard to production estimates and linked to enhance the performance of the existing models of population dynamics applied to a wide variety of lakes worldwide in terms of morphometry, nutrient status, and light environments. Estimates of PP were shown to be sensitive to changes in phytoplankton sinking and zooplankton grazing rates in both methods. Production estimates in the process-oriented PP model were also sensitive to light-associated parameters such as day length. Although the production estimated from the population dynamics-based PP calculation tended to be lower than that from the process-oriented PP model irrespective of lake morphometry, production estimates calculated from both methods with standard parameterization were comparable when production was estimated on an annual timescale.However, it was also shown that the alternative methods could produce different production estimates when estimated on shorter timescales such as cyanobacterial blooms in summer. Cyanobacteria with low mortality due to grazing and sinking losses have been considered as trophic bottlenecks, but there is increasing evidence that their mortality is, to a considerable extent, due to parasitic pathogens. In the case of cyanobacterial blooms, an addition of parasite-related loss term (19%-33% of standing stock) resulted in a resolution of the difference in production estimates between the methods. These analyses theoretically support the critical role of parasitism and resolve the bottleneck problem in aquatic ecosystem metabolism.
