“…For example, many studies have identified differences between pelagic and littoral habitats with respect to both primary and secondary production (Lindeman 1942;Wetzel 1995;Vadeboncoeur et al 2002). Within littoral zones, patchiness of benthic substrate types may drive spatial heterogeneity in rates of metabolism (Vadeboncoeur and Lodge 2000;Lauster et al 2006;Vadeboncoeur et al 2006). In pelagic zones, studies have shown that even moderate physical forcing can create patches of differing nutrient concentrations and abundances of producers and consumers (Caron et al 2008;Blukacz et al 2010;Mackay et al 2011).…”

To characterize the spatial variability of metabolism estimates (gross primary production [GPP], respiration [R], and net ecosystem production [NEP]) in two Northern Wisconsin lakes, we collected data from 27 and 35 dissolved oxygen sensors placed in a two-dimensional array throughout the upper mixed layers over a period of 10 d per lake in midsummer. Averaged over the deployment, aerial metabolism estimates among sensor locations varied 1-2 orders of magnitude and were largely unrelated to physical habitat within the lake. For all sites and days, 76-90% of the explainable variance in GPP and R was attributable to location in the lake rather than day of the deployment. NEP, on the other hand, was less affected by location, with 79-93% of the explained variance attributable to the day of the deployment. Single-location estimates can yield errors of more than an order of magnitude in estimates of daily GPP and R and can mischaracterize the trophic status of the lake. Using a rarefaction approach, we found that using four randomly placed sensors increased the precision of the resulting daily metabolism estimates fourfold over single-location measures in both lakes.

“…However, most measurements of whole-lake benthic and pelagic primary production date back to the International Biosphere Program of the 1960s and 1970s. Unfortunately, these studies used a wide variety of methods and lack the accompanying phosphorus data needed to compare phytoplankton and periphyton responses to nutrient enrichment (summarized in Westlake et al [1980] and Vadeboncoeur and Steinman [2002]). …”

Benthic community responses to lake eutrophication are poorly understood relative to pelagic responses. We compared phytoplankton and periphyton productivity along a eutrophication gradient in Greenland, U.S., and Danish lakes. Phytoplankton productivity increased along the phosphorus gradient (total phosphorus [TP] ϭ 2-430 mg m Ϫ3 ), but whole-lake benthic algal productivity decreased, substantially depressing increases in primary productivity at the whole-lake scale. In shallow, oligotrophic Greenland lakes, periphyton was responsible for 80-98% of primary production, whereas in Danish lakes with TP Ͼ 100 mg m Ϫ3 , phytoplankton were responsible for nearly 100% of primary production. Benthic contributions ranged from 5 to 80% depending on morphometry and littoral habitat composition in lakes with intermediate phosphorus concentrations. Thus, eutrophication was characterized by a switch from benthic to pelagic dominance of primary productivity. Carbon stable isotope analysis showed that the redistribution of primary production entailed a similar shift from periphyton to phytoplankton in the diets of zoobenthos. Benthic and pelagic habitats were energetically linked through food web interactions, but eutrophication eroded the benthic primary production pathway.

“…Many studies have confirmed that the biomass of periphyton is positively correlated with total phosphorus (TP) concentration in water [7][8][9]. However, some studies indicate that enrichment concentrations may have little or negative effect on periphyton biomass [10][11][12].…”

“…However, some studies indicate that enrichment concentrations may have little or negative effect on periphyton biomass [10][11][12]. For example, P fertilization did not cause any increase in epipelic production both in laboratory and actual lake conditions [9,13]. Even in large scale, losses of periphyton also occurred due to excessive P enrichment [14,15].…”

An experiment was conducted to investigate the response of periphyton biomass to addition of phosphorus (P) in an aquatic ecosystem dominated by submersed plants. Aquatic ecosystems dominated by Hydrilla verticillata (L.f.) Royle and Vallisneria natans (Lour.) Hara were constructed in mesocosm aquaria. Mesocosms were dosed weekly with different P loads (0 µg/L/Week and 100 µg/L/Week) for 17 weeks. Total P (TP), total soluble P (TSP), and soluble reactive P (SRP) concentrations in the waters of mesocosms added with P were significantly higher as opposed to the unenriched control mesocosms. The biomass of the attached periphyton and the cover of floating periphyton remained abundant in P-unenriched control mesocosms throughout the test period with a TP, TSP, and SRP concentration ranging of 0.021 -0.049 mg/L, 0.004 -0.024 mg/L, and 0.003 -0.018 mg/L, respectively. P addition caused the decline of attached periphyton biomass to a low level and loss of floating periphyton. Results indicate that P enrichment in an aquatic ecosystem dominated by submersed plants could reduce attached periphyton biomass and eliminate floating periphyton. The research would be useful to maintain periphyton by reducing excessive P in aquatic ecosystem dominated by submersed plants.
