    Notes: Abstract A synoptic survey of the distribution and abundance of occurrence of bloom-forming Cyanobacteria in 55 lakes in the Republic of Ireland revealed strong positive correlations with the traditional trophic gradient. Analysis of the data shows that the perceived trophic state may be correctly viewed as a function of phosphorus availability. The distribution of dominant bloom-forming Cyanobacteria is strongly related to the geology of the catchments and the incidence of significant bicarbonate buffering.

    Description / Table of Contents: A Contribution on Ternary Oxides of the AMO4-Type (A = Ti3+, Cr3+; M = Nb5+, Ta5+)CrNbO4, CrTaO4, TiNbO4, and TiTaO4 were prepared by CO2-laser technique. X-ray single crystal investigations show a random distribution of the metal ions in Rutil type structure, space group D4h14-P42/mnm. Calculations of the free energy of reaction between Ti2O3 and Nb2O5 show higher stability of TiO2 beside NbO2. In TiNbO4 both metals exhibit the oxidation state +4.
    Notes: CrNbO4, CrTaO4 TiNbO4 und TiTaO4 wurden einkristallin mit CO2-Lasertechnik dargestellt und röntgenographisch untersucht. Sie kristallisieren mit statistischer Verteilung der Metallionen im Rutiltyp, Raumgruppe D4h14-P42/mnm. Berechnungen der freien Reaktionsenthalpie zeigen, daß Ti2O3 nicht neben Nb2O5vorliegt. In TiNbO4 haben beide Metallionen die Oxidationsstufe +4.
