Volume: 89 Issue: 3 Pages: 382-386 Keywords: morphology (organisms); nitrogen fixation; Gloeotrichia echinulata photosynthesis; light effects; anoxic conditions; Algae Freshwater Q1 01481 Productivity Abstract: Membrane-like colonies of G. echinulata , containing mostly short trichomes, showed higher photosynthetic activity than cluster-like colonies with long trichomes. The nitrogen fixing capacity of membrane-like colonies with high heterocyst ratios was 300-800% higher than that of cluster-like colonies with low heterocyst ratios in weak light cultures, but not in high light cultures.

In the N-free medium, the alga grew well, fixed N, and formed 2.3% heterocysts in the filaments. The addn. of Ca(NO3)2 of ?300 mg/mL to the medium did not affect growth or N-fixation adversely, and N-fixation was greater with an increase in the incubation period of ?25 days. There was a gradual decrease in the heterocyst frequency with increasing concns. of Ca(NO3)2, with complete suppression of heterocyst differentiation at a concn. of 1000 mg/mL. With higher concns. of NO3-, the filaments were elongated due to the low extent of differentiation or absence of heterocysts, and the cells were granulated.

Volume: 51 Issue: 4 Pages: 428-433 Keywords: growth; phytoplankton culture; amino acids; Gloeotrichia population density; nitrogen Freshwater Q1 01226 Physiology, biochemistry, biophysics; Q1 01585 Plant culture Abstract: Gloeotrichia was cultured from water-logged rice fields and the effect of amino acids (tryptophan, glutamic acid, histidine and proline) was studied on the growth and heterocyst differentiation in medium free from combined nitrogen. The addition of 10 to 20 g.mlSUP--1 of amino acids encouraged growth as evidenced by increase in optical densities after various incubation times whereas the concentrations of 80-100 g.mlSUP--1 caused its gradual reduction. The heterocyst frequency varied from 1.3 to 2.9 in control cultures as well as in the presence of amino acids. There was no significant effect on the heterocyst frequency. Low concentrations of organic nitrogen encouraged the growth of alga without altering heterocyst frequency significantly.

Pages: [np] Accession Number: 5197924 Keywords: Freshwater Q1 01224 Reproduction and development Abstract: Plankton colonies of Gloeotrichia echinulata collected from Conesus Lake, NY, during the summer of 1972 did not show any akinetes. The surface water temperature of the lake ranged from 19 degree C in the early morning hours to 27 degree C in the later afternoon. When these colonies were cultured in the laboratory at 21 degree C and 15 degree C for similar to 3 weeks, akinetes developed. The order of frequency of induction of akinetes decreased with decreased temperature. Akinetes from the induced colonies were isolated for the purpose of studying the frequency of germination by homogenation followed by centrifugation. When the isolated akinetes were placed in fresh medium, the frequency of germination increased with time up to 2 weeks. The germination could not be followed into the 3rd weeks as the germlings started developing and occasionally releasing akinetes of their own. There seems to be 2 modes of releasing germlings from the akinetes. Notes: 1973. 0022-3646 Records keyed from 1973 ASFA printed journals English

The biomass of Gloeotrichia, its photosynthetic activity, chlorophyll content, assimilation number, calorie content and wet and dry weights were determined. The results show that the productivity of Gl. echinulata is significantly lower than that of the smaller lake plankters. Nevertheless, at the high biomass which might be formed by Gloeotrichia in the reservoirs its role becomes significant. Notes: 1969. 11 refs. Records keyed from 1971 ASFA printed journals.

After the collapse of Soviet-type agriculture in the early 1990 s, total N loadings decreased sharply while the in-lake total P concn. increased, forming favorable conditions for harmful bloom-forming N2 fixing (N2fix) cyanobacteria. The av. percentage of the biomass of N2fix cyanobacteria in total phytoplankton biomass increased from 13 % in 1983-1991 to 29 % in 1992-2001. Gloeotrichia echinulata, a species capable of vertical migration and consequent transport of P from the lake bottom to the upper layers developed earlier in the season (June) at lower nutrient concns. than other cyanobacteria in L. Peipsi (Anabaena, Aphanizomenon, Microcystis). The fixation of N2 by G. echinulata as well as its ability to use sediment phosphorus could bring about the enrichment of the water column with nutrients. This enables the other N2fix species Anabaena and Aphanizomenon as well as Microcystis, which is not generally N2 fixing but requires high nutrient concns., to flourish.

Year: 2004 Title: Planktonic algae and epiphyton of the littoral in Lake Peipsi, Estonia Journal: Limnologica Volume: 34 Issue: 1-2 Pages: 90-97 Date: May Accession Number: ISI:000222030800012 Keywords: littoral algae; epiphyton; Phragmites australis; Potamogeton perfoliatus phytoplankton; macrophytes; plants Abstract: The littoral plankton of Lake Peipsi (3555 km(2), mean depth 7.1 m) was studied in summer 1980 and 2000-2002, and the epiphyton was studied on two dominating macrophytes, Phragmites australis (CAV.) TRIN. ex. STEUD. and Potamogeton perfoliatus L., in 2000. The purpose of the study was to estimate to what extent the littoral phytoplankton and epiphytic algae (their biomass, chlorophyll a content and dominant species) can be used as a criterion for the trophic state of the lake. In wind-open areas, phytoplankton biomass in the littoral is commonly more than ten times higher than in open water due to the presence of the macroscopic cyanobacterium Gloeotrichia echinulata (J.S. SMITH) P. RICHTER. This alga is abundant in the moderately eutrophic northern lake's part and rare in the strongly eutrophic southern part; hence also biomass in the southern part is considerably lower. In open water, phytoplankton biomass increases southward with increasing trophy. Algal biomass in the littoral depends on wind direction and can change completely in a few days. Epiphyton biomass and Chla content increased southward with increasing trophic state. They both revealed significant Spearman correlations (P < 0.05) with wind index and transparency (negative), and with abundance of the host plant, both reed and pondweed (positive). The phytoplankton biomass of the littoral of the large and shallow Lake Peipsi can not be used as a criterion of trophic state, however, the species composition of the dominants, particularly cyanobacteria, is well applicable for this purpose. The biomass and Chla content of the epiphyton can be used as a criterion for trophic state.

blue-green-algae; cyanobacterium gloeotrichia-echinulata; phytoplankton community; planktonic cyanophyceae; gloetrichia-echinulata; seasonal periodicity; akinete germination; eutrophic lake; flos-aquae; water Abstract: Recruitment of Anabaena and Aphanizomenon from the sediments to the water column was investigated in shallow (1-2 m) and deep (6-7 m) areas of Lake Limmaren, central Sweden. Recruitment traps attached to the bottom were sampled weekly throughout the summer season (June through September). A comparison between the two sites shows that the largest part of the recruited cells originated from the shallow site, although recruitment occurred at all depths in the lake. There were also differences between the species, regarding the site as well as the timing of the recruitment. The contribution of the inoculum to the pelagic population was calculated to vary between 0.003% and 0.05% for the different species. From these results we conclude that shallow sediments are more important than deep ones for the recruitment and that the inoculum in Lake Limmaren is small but may still be an important factor in the population dynamics.

The influence of light, temperature, sediment mixing and sediment origin (water depth) on the recruitment of the cyanobacterium Gloeotrichia echinulata was examined in the laboratory. 2. Light and temperature were the most important factors initiating germination in G. echinulata. 3. The extent of germination (recruited biovolume) was mainly regulated by temperature and sediment mixing. Furthermore, sediment mixing significantly enhanced the frequency of observed heterocysts and colonies. 4. Despite the fact that the deep and shallow sediments contained a similar number of akinete colonies, the highest recruitment occurred from shallow sediments, indicating that akinetes from shallow sediments have a higher viability than those from deeper parts of the lake. 5. Our results support the hypothesis that shallow sediments are more important than profundal sediments for the recruitment of G. echinulata to the pelagic zone.
