Abstract: The peat bog in Dubravica is of spread interest due to ist overgrowing by the process of natural succession, causing the habitat to become dryer and shadier. The dominance structure and phenology of wolf spiders on the Dubravica bog was studied. The spiders were collected during the period 09.04.-9.10.1995, using 20 pitfall traps. Altogether 10 lycosid species were found among 723 adult individuals. For six more abundant species phenology graphs are presented. Three species are found to be eudominant: Pardosa lugubris, Trochosa spinipalpis and Hygrolycosa rubrofasciata. The lycosids habitat preferences and dominance structure according the habitat condition and species occurences on some other European bogs are discussed. 55,2 % caught specimens are hygrophilous species, and only 7,6 % are photophilous. The lycosid fauna and dominance structure does reflect the habitat condition. As overgrowing is not fully progressed yet, the lycosid fauna of this bog is still relatively bog-characteristic.
