DYNAMIKA STŘEVlÍKOVITÝCH (Carabidae) LUŽNÍHO LESA JIŽNÍ MORAVY

Abstract

During the years 1993–2001 the monitoring of the soil surface invertebrates was carried out in the flood- plain forest in the Ranšpurk National Nature Reserve (Southern Moravia). The dynamics of carabid beetles is described in detail in this paper. A total of 8 529 individuals belonging to 67 carabid species was collected. The most abundant species were Pterostichus niger (Schaller, 1783), Nebria brevicollis (Fabricius, 1792), Carabus ullrichi Germar, 1824, Carabus violaceus Linnaeus, 1758, Abax carinatus (Duftschmid, 1812), Patrobus atrorufus (Stroem, 1768), Pterostichus melanarius (Illiger, 1798), Carabus granulatus Linnaeus, 1758, Poecilus cupreus (Linnaeus, 1758), Bembidion mannerheimi C. R. Sahlberg, 1827 and Epaphius secalis (Paykull, 1790). During the years 1993–1996 the species composi- tion indicated especially the drainage of the locality. In July 1997, a disastrous flood affected all groups of invertebrates, including the carabids. The abundance of hygrophilous species increased extremely during the years after the flood. The summer flood showed that the submersion of the soil surface had higher impact on carabid taxocenoses than flooding by system of canals.
