STEPHANODISCUS ALPINUSIN PLUßSEE, GERMANY. ECOLOGY, MORPHOLOGY AND TAXONOMY IN COMBINATION WITH INITIAL CELLS
Autor: Hannelore Håkansson, Barbara Hickel
Publikováno v: Diatom Research. 8:89-98
Long-term observations (1972–1992) at mainly weekly intervals on the phytoplankton of the eutrophic, summer stratified kettle-hole lake Plussee, northern Germany have revealed Stephanodiscus alpinus Hustedt as an important component of the spring d

THE FRESHWATER DIATOMAULACOSEIRA HERZOGII
Autor: Hannelore Håkansson, Barbara Hickel
Publikováno v: Diatom Research. 6:299-305
The fine structure of the frustules of the rarely recorded planktic freshwater diatom Aulacoseira herzogii (Lemmermann) Simonsen was studied in detail using material from River Solimōes (Brazil) and Lake Drummond (USA). A. herzogii is characterized

Publikováno v: FEBS letters. 449(2-3)
Astrocytes (AC) induce blood-brain barrier (BBB) properties in brain endothelial cells (EC). As antioxidative activity (AOA) is assumed to be a BBB characteristic, we tested whether AC improve AOA of EC. Monocultivated AC showed higher AOA [manganese

The Plussee is situated in Schleswig-Holstein in northern Germany at 10° 23′ east and 54° 10′ north. During the last glacial period, about 12,000 years ago, the lake was formed as a kettle lake and has a very regular shape. Figure 1.1 shows the

Identification of the bloom-formingPeridiniumfrom Lake Kinneret (Israel) asP. gatunense(Dinophyceae)
Autor: Utsa Pollingher, Barbara Hickel
Publikováno v: British Phycological Journal. 23:115-119
Plate structure analysis of the bloom-forming Peridinium of Lake Kinneret (previously identified as P. cinctum fa. westii) established its identity as P. gatunense. Peridinium cinctum was not observed. Material from different years and periods of the

Autor: Gertrud Cronberg, Barbara Hickel
Publikováno v: Nordic Journal of Botany. 5:105-110
Two new species of Mallomonas (Chrysophyceae, Mallomonadaceae) are described from tropical lakes. M. fenestrata sp. nov. was found in Lago Tupe (Brazil) and M. perforata sp. nov. in Lake Danau Bratan (Indonesia), Negril ponds (Jamaica) and Marondera
