Zur Bedeutung der paläobotanischen Untersuchungen des Mineralogen und Paläontologen Carl Justus Andrae (1.11.1816 - 8. 5.1885)
Full text linkRäumliche und zeitliche Verteilung der Spinnentier- (Arach.: Araneida, Opilionida) und Laufkäferfauna (Col.: Carabidae) im NSG Radauer Born (Hochharz)
Full text link.Investigations of the spider-, harvestmen- and ground beetle fauna had been performed at six sites within and in the vicinity of a hercynian raised bog in the years 1983 and 1988. The animals were caught with barber-traps. In parallel microclimatic factors (light and temperature) and vegetation were registered at each site. In total 118 species of spiders, 6 species of harvestmen and 22 species of ground beetles were found. The fauna of raised bog-sites, fen-sites and spruce forest-sites clearly differed. For 13 spider species and two ground beetle species brief ecological and zoogeographical characteristics are given. Phenological data are presented for five species of spiders. Possible changes in species and specimens composition within five years are discussed as well as the binding of spiders to raised bogs. An attempt is made to explain zoogeographical distribution patterns of moor spiders
Metcalfa pruinosa (Say, 1830) introduced into the Czech Republic: (Hemiptera, Flatidae)
Full text linkA large population of the Nearctic planthopper Metcalfa pruinosa (Say, 1830) (Hemiptera, Flatidae), introduced and acclimatized in South Europe in late 1970's, was found in 2001 in an outdoor ornamental gardening shop in the city of Brno in the Czech Republic, being the first record of the species and the family in the country and its northernmost record in Europe. M. pruinosa, probably introduced in the egg stage on ornamental shrubs from Italy, prefered young twigs of Thuja occidentalis, Juniperus communis and Sorbus aucuparia and was also found in numbers on Lilium spp. The damage on affected plants was rather of an aesthetic kind (spots of waxy filaments on shoots), even though a production of honeydew and a consequent development of sooty moulds was also observed. A brief review of published information on the distribution, biology and economic importance of M. pruinosa is given
