“…Thames (150-285 lg l -1 ; Ruse and Hutchings 1996;Young et al 1999), Elbe (263 lg l -1 ; Desortová et al 1996) and Meuse ([160 lg l -1 ; Gosselain et al 1998b). In the above examples, the rivers have higher concentrations of phosphorus (with mean annual TP concentrations ranging from 150 lg P l -1 to [1,000 lg P l -1 ), suggesting, as evidenced in recent studies (Basu and Pick 1996;Van Nieuwenhuyse and Jones 1996;Heiskary and Markus 2001;Chételat et al 2006), a dependence of chlorophyll a on nutrient concentrations. On the other hand, as we have seen, low velocity during high discharge does not appear to allow the formation of very high algal biomass.…”

The principal environmental factors influencing the seasonal dynamics of phytoplankton were examined from September 1997 to July 1998 in three stations along a 26-km stretch of the lowland course of River Adige (northeast Italy). Nutrient concentrations did not appear to be limiting for the phytoplankton growth. Annual minimum concentrations of reactive and total phosphorus, and dissolved inorganic nitrogen were 22 lg P l -1 , 63 lg P l -1 and 0.9 mg N l -1 , respectively. The most critical forcing factors were physical variables, mainly water discharge and other variables related to hydrology, i.e. suspended solids and turbidity, which acted negatively and synchronously by diluting phytoplankton cells and decreasing light availability. Higher algal biomass was recorded in early spring, in conditions of lower flow velocity and increasing water temperature. In late spring and summer, higher water discharge caused a decrease in phytoplankton biomass. Conversely, low algal biomass in late autumn and winter, during low discharge, was mainly related to low water temperatures and shorter photoperiod. Physical constraints had a significant and measurable effect not only on the development of total biomass, but also on the temporal dynamics of the phytoplankton community. Abiotic and biotic variables showed a comparable temporal development in the three sampling stations. The small number of instances of spatial differences in phytoplankton abundance during the period of lower flow velocity were related to the increasing importance of biological processes and accumulation of phytoplankton biomass.

“…Despite many models of chl a and TP, most are linear regression, in which R 2 ranged from 0.42 to 0.95 (e.g., Dillon and Rigler 1974;Mazumder 1994;Jones and Knowlton 2005). This means that other factors, such as light, alkalinity, catchment area, and mixing regime, could affect the stimulation of TP-chl a relationship (Nichols and Dillon 1978;Ahlgren et al 1988;McCauley et al 1989;Van Nieuwenhuyse and Jones 1996;Masson et al 2000;Havens and Nürnberg 2004;Huszar et al 2006). However, the effect of temperature was seldom considered in building the model between chl a and TP.…”

An experiment was carried out to evaluate the effects of phosphorus concentration (1, 4 and 10 mg l -1 ) and temperature (15 and 25°C) on chlorophyll a (chl a) contents and cell size/volume of green alga Scenedesmus obliquus and blue green alga Microcystis aeruginosa. Long-term field data from Lake Taihu, a large, shallow eutrophic lake between Jiangsu and Zhejiang Provinces, China, was also used to evaluate the effect of temperature on the model between chl a and total phosphorus (TP). The chl a content of both algae increased with an increase in phosphorus concentration and temperature. Temperatures showed a significantly different effect on chl a content of S. obliquus at a phosphorus concentration of 10 mg l -1 , whereas there was no significant difference at the two lower phosphorus levels. For M. aeruginosa, temperatures presented significantly different effects on the chl a contents at three phosphorus concentrations. Chl a content of neither alga presented an interaction between the nutrient and the temperature. Long-term field data from Lake Taihu also indicated that the addition of temperature to the model increased predictability of chl a by TP. The length/diameter and volume of both algae were greater at the lower temperature and phosphorus concentration. Moderate negative correlations were observed between algal size, volume, and chl a content. Our results suggest that phosphorus concentration and temperature could change chl a contents and size in species-specific algal cells and that temperature should be considered when building the model of TP and chl a concentration.

“…Factors such as nutrients, turbidity, temperature, light, and hydrological regime can control sestonic algae and periphyton in streams (Bothwell, 1988;Bushong & Bachmann, 1989;Rosemond, 1993;Biggs, 1995;Van Nieuwenhuyse & Jones, 1996;Hill & Dimick, 2002). Midwestern streams tend to have high concentrations of N and P due to the application of fertilizers used in agricultural fields to enhance the productivity of crops (Fausey et al, 1995;David et al, 1997;David & Gentry, 2000).…”

“…The concentration of sestonic chlorophyll-a (chl-a) has been related to total P across a range of streams (Van Nieuwenhuyse & Jones, 1996) and periphytic chl-a is often controlled by dissolved nutrients (e.g., Lowe et al, 1986). Although N and P can limit algae, these nutrients do not always relate strongly to the abundance of chl-a, particularly in P-enriched streams (Van Nieuwenhuyse & Jones, 1996).…”

“…Although N and P can limit algae, these nutrients do not always relate strongly to the abundance of chl-a, particularly in P-enriched streams (Van Nieuwenhuyse & Jones, 1996). Bushong & Bachmann (1989) found that P enrichment never stimulated periphyton growth in agriculturally influenced streams in Iowa and concluded that background N and P concentrations were sufficient for algal demands.…”

Nitrogen and phosphorus are the primary nutrients that affect water quality in streams in the midwestern USA and high concentrations of these nutrients tend to increase algal biomass. However, how nutrients interact with physical controls in regulating algal biomass is not well known in agricultural streams. Eighteen streams in east-central Illinois (USA) were sampled during June and September 2003 to analyze factors possibly regulating algal biomass. Additionally, two shaded and two non-shaded sites in the Embarras River in east-central Illinois were sampled intensively from June to December 2003. Both sestonic and periphytic chlorophyll-a (chl-a) were analyzed, and periphytic chl-a was assessed on natural substrata and unglazed ceramic tiles. Although high concentrations of nutrients were found in these streams (mean total P=0.09-0.122 mg l )1 and mean NO 3 -N=4.4-8.4 mg l )1 ), concentrations of sestonic chl-a were low among all sites and both sampling periods (<18 mg m )3 , median values of 5 and 3 in June and September, respectively). Filamentous algae were an important component of the algal communities in streams with stable substrata. Periphytic chl-a was generally not related to the concentration of N or P in the water column, and in non-shaded streams periphyton appeared at times to be light-limited due to turbid water. Turbidity was found to be an important factor controlling chl-a on ceramic tiles across the 18 sites and for the Embarras River sites; chl-a decreased exponentially in concentration (132-0 mg m )2 ) as turbidity increased from 4 to 39 NTU (r 2 =0.80). In general, the interaction between hydrology and light (turbidity) likely controlled algal biomass in these nutrient-rich, agricultural streams.
