“…The relatively low chlorophyll-a content of periphyton observed in Lake Veluwe, indicates that a large fraction of the organic matter of periphyton was detrital or heterotrophic or both. A qualitative interrelationship between the phytoplanktonic and periphytic algae has been demonstrated in eutrophic waters (Moss, 1981;Jenkerson & Hickman, 1986). The seasonal variation in relative abundance of epiphytic algae presented in this paper coincided with that of phytoplanktonic algae (Van Dijk & Achterberg, 1992).…”

The seasonal variation in periphyton dynamics has been studied upon artificial substratum (microscopic glass slides) under various light conditions during the periods May-October 1986 and May-September 1987, in Lake Veluwe. Some additional observations on the periphyton development upon leaves of Potamogeton pectinatus L. have been made simultaneously. Four different light conditions were created in an experimental setup by manipulating the photon flux density through artificial shading.Periphyton upon artificial substratum exhibited a relatively high abundance with a distinct seasonal pattern. Periphyton accrual rates were highest at the beginning of June and in August and September upon slides which were incubated for two weeks. Periphyton mass increased during May and June, decreased or remained about the same during July and subsequently increased until an upper plateau was reached upon slides which were incubated from the beginning of May onwards.Generally, periphyton mass was lower upon slides than upon P. pectinatus. The seasonal variation in periphyton mass was more pronounced upon P. pectinatus leaves than upon the slides.Attenuation by periphyton upon slides ranged from 5 to 65 % after two weeks of incubation. Periphyton upon slides which had been incubated for more than two weeks demonstrated an attenuation of more than 85%.Water quality parameters other than photon flux density were probably more important in determining the periphyton dynamics, since only minor differences were observed in periphyton mass between the various light conditions. Chlorophyll-a content was higher with increased shading on various sampling dates.Periphyton, especially 'older' periphyton consisted largely of settled silt and clay particles and to a lesser extent of detrital matter on both substrata. Living epiphytes were only a relatively small fraction.It is concluded that a reduction of resuspension of sediment particles, giving less suspended matter in the water column, will result in lower periphytic mass. Consequently, the quantity of photosynthetically active radiation reaching the submerged macrophytes is expected to increase considerably. 144

“…The plankton and periphytic algae do not seem to depend solely on current conditions in the environment, but also on its past history (Moss, 1981). In aquatic tropical ecosystems, the seasonal growth period has been linked more to specific incidents of water input into the system throughout the year than to light and temperature regimes (Moss, 1981). Studies on the influence of the hydrological cycle on the nutrient dynamic of a periphytic community in tropical regions are scarce.…”

The temporal variations in C, N and P concentrations of the periphyton on the natural substratum (Echinochloa polystachya) and its relationships to the water's climatological (air temperature and precipitation), hydrodynamic (water discharge and water level), physical (temperature, transparency) and chemical variables (conductivity, total suspended solids, nitrate, nitrite, ammonia, silica, total phosphorus and orthophosphate)were evaluated in a lagoon at the Paranapanema River mouth into the Jurumirim Reservoir (Sao Paulo, Brazil) from August 1993 to July 1994. An amplitude variation of 2.0 m in water level was observed.Depending on to the hydrologic conditions, the lagoon presents intermediate conditions of lentic and lotic environments.The amplitude variations in C, N and P were 14.5-52.1%C DW-1, 0.5-3.2% N DW-1, and 0.03-0.4% P DW-1, respectively.The periphyton presented a decreased protein content. The environmental trophic degree appears to be decisive in chemical periphyton composition.

“…Such bioassays have included both laboratory and in situ lake studies (Glass 1973, Middlebrooks et al 1976 1979). In situ methods have most commonly used closed plastic or glass containers suspended in the water column (Schelske et al 1975, Komarkova 1979 or open tubes reaching from the surface into the lake sediments (Moss 1981).…”

Differences in nutrient limitation for dominant species within an algal periphyton com? munity were determined using additions of N and P supplied by nutrient-diffusing artificial substrates. Sealed clay flowerpots were filled with 2% agar and one of nine nutrient treatments (all combinations of K2HP04 at 0.0, 0.05, and 0.5 mol/L with NaN03 at 0.0, 0.05, and 0.5 mol/L). The pots were submerged at 0.5 m depth in Douglas Lake, Michigan, and diffused N and P to their outer surfaces in proportion to internal concentrations. After 51 d the pots were scraped and analyzed for attached algae. Ecological Society of AmericaTotal algal biomass as chlorophyll a on the pots ranged from 0.17 ? 0.02 (se) ^g/cm2 for pots without added nutrients to 15.7 + 2.0 /xg/cm2 for pots with K2 HP04 at 0.05 mol/L and NaN03 at 0.5 mol/L. Chlorophyll a on pots containing just P (0.05, 0.5 mol/L) increased 6-to 10-fold over controls. The diatoms Epithemia adnata and Rhopalodia gibba and the blue-green alga Anabaena in? creased significantly on the P-only pots; these species are suspected of N-fixing capability. Chlorophyll a on pots containing just N (0.05, 0.5 mol/L) increased 1.5-to 2-fold, though this increase was nonsignificant; Achnanthes minutissima, Gomphonema tenellum, and Cocconeis placentula showed enhanced growth on these pots.Combinations of N and P caused heavy growths of the filamentous alga Stigeoclonium tenue. Naviculoid diatoms were also most abundant on the N + P pots.Average nutrient levels in Douglas Lake during the study were: NH3, 2.02 /nmol/L; N03, 0.44 Aimol/L; and P04, 0.06 /miol/L. The low ambient concentrations of both N and P, together with results ofthe periphyton bioassay, indicate that the two nutrients may jointly limit overall growth, and that the form of growth limitation differs by species within the periphyton community.
