Studies on chrysophyceae from some ponds and lakes in Alaska vi occurrence of synura species (original) (raw)
Summary
The Synura species found in samples from a variety of freshwater habitats in Alaska are identified by electron microscope studies of their scales. Synura petersenii f. macracantha Petersen & Hansen and Synura spinosa f. curtispina Petersen & Hansen are raised to specific rank. Synura petersenii f. praefracta n. f., Synura curtispina f. reticulata n. f., and Synura echinulata f. leptorrhabda n. f. are described. Electron micrographs of some scales belonging to undesignated formae are given.
Some remarks on the ecology of the Synura species are given.
Zusammenfassung
Synura Arten, die in Proben aus verschiedenen Süßwasser-Lokali-täten in Alaska gefunden werden sind, werden durch elektronenmikroskopische Untersuchungen ihrer Schuppen beschrieben. Zwei Formen, Synura petersenii f. macracantha Petersen & Hansen und Synura petersenii f. curtispina Petersen & Hansen, werden zur Rangstufe der Arten erhoben. Zwei neue Formen, Synura petersenii f. praefracta and Synura curtispina f. reticulata, werden beschrieben.
Elektronen-mikroscopische Abbildungen einiger Schuppen, die von unbeschriebenen Formen herrühren, werden gegeben.
Einige Anmerkungen über die Ökologie der _Synura_-Arten werden gemacht.
