They pose a serious threat to human and animal health, each year being responsible for several cases of animal fatalities (mammals, fish, birds). In Polish water bodies, toxic cyanobacterial blooms are frequently obsd. In this work, a procedure for anatoxin-a anal. was modified to obtain a sensitive, selective method for routine studies of bloom samples. The presence of cyanobacterial neuro- and hepatotoxins in freshwater and brackish water of Pomorskie Province was examd. Hepatotoxins, microcystins or nodularin, were detected in all phytoplankton samples dominated by the cyanobacteria, Microcystis and Anabaena genera or by Nodularia spumigena. HPLC-diode array detector anal. showed the presence of anatoxin-a in only 1 sample collected in coastal water of the Gulf of Gdansk dominated by Anabaena. [on SciFinder (R)] Notes: CAN 140:64378 61-2

After germination of the akinete there is a short phase of growth on the sediment before the filaments develop gas vacuoles and migrate up into the water. It has been indicated that during the time of growth on the sediment surface the germlings take up nutrients. Those nutrients would be used during the pelagic phase as the pelagic colonies do not have a very efficient nutrient uptake. To test the length of the initial growth period 'akinete colonies' were picked out of sediment samples from Lake Erken, Sweden, and placed on a thin layer of sediment in wellplates (Nunclon multidish, 48 wells) in an incubator with 17degreesC and a light:dark cycle of 16:8 h. The plates were then studied under a stereo microscope and pictures were taken one or two times per day for 20 days. Germination occurred in one third of the wells and the growth was recorded. The germlings formed bundles on the surface of the old akinete colony during the experiment. Several bundles were found on the same akinete colony. In the migration traps colonies and filament bundles were found. The morphology of filament bundles found in the migration traps was similar to the filament bundles found in the germination experiment which had reached a stage of development where they would soon be considered colonies.

Freshwater Q5 01521 Mechanical and natural changes Abstract: The study is based on a large hydrochemical and hydrobiological database of the shallow non-stratified Lake Peipsi, Estonia (3550 km super(2), mean depth 7.1. m) covering the period of significant decrease of external nutrient loading since the second half of 1980s. The effects and interactions of nutrient level, natural interannual water level fluctuations, and biota are estimated with advanced statistical methods. Along with clear changes in biota, certain resilience effects will be demonstrated. In Lake Peipsi, strong and long-lasting algal blooms were observed in recent years. In phytoplankton groups that demand less nutrients, as cyanobacteria (blue-green algae) have become more dominating. In the hot and dry summer 2002, blooming of cyanobacteria Gloeotrichia echinulata started in L. Peipsi s.s. in early June. Strong cyanobacterial bloom led to fish-kill in the lake, which was induced by synergistic effect of several unfavourable conditions: high temperature, low water level, great spatial and temporal variations in oxygen (saturation 25%-165%) and ammonium ion (up to 0.33 mg N 1 super(-1) content as well as in pH (7.7-9.5).

Year: 2003 Title: Misuse of inorganic N and soluble reactive P concentrations to indicate nutrient status of surface waters Journal: Journal of the North American Benthological Society Volume: 22 Issue: 2 Pages: 171-181 Date: Jun Accession Number: ISI:000183594300001 Keywords: ammonium; dissolved reactive phosphorus; inorganic nutrients; nitrate; nutrient limitation; phosphate; water-quality monitoring large oligotrophic lake; prairie streams; algal biomass; nitrogen; phosphate; limitation; phytoplankton; phosphorus; patterns; regeneration Abstract: Dissolved inorganic N (DIN) and soluble reactive P (SRP) have been used by some to indicate the trophic status of waters, and concentration ratios (DIN:SRP) to indicate nutrient deficiency. The utility of such measurements should be questioned, particularly based on well-known problems associated with determination of the concentration of SRP, which is commonly assumed to represent PO43-. Another potential problem with using inorganic nutrient pools to represent trophic state and nutrient availability ratios arises because concentration values are in units of mass per unit volume, and cannot be used with certainty to estimate supply (i.e., turnover rate of the nutrient pool, expressed either in mass per unit volume per unit time or simply as per unit time) to organisms without information on uptake and remineralization. Two data sets with lotic water-column nutrient values were explored, a large, continental-scale data set with analyses and collections done by many laboratories, and a more limited data set collected and analyzed by the same laboratory. In concert, the data sets indicated that at high total N (TN) (i.e., >5 mg/L) and total P (TP) (i.e., >2 mg/L) concentrations, >60% of the nutrient is usually made up of dissolved inorganic forms, but at low levels the ratio of dissolved inorganic to total nutrients is highly variable. Last, DIN:SRP is a weak surrogate for TN:TP and thus should be used with caution to indicate nutrient limitation.
