The biotic diversity of springs is specific, which makes them valuable sites important for nature protection. Springs located in the Krakow-Częstochowa Upland (southern Poland) are characterized by low variability of environmental conditions, but their benthic fauna composition is considerably different. Benthic invertebrates, water chemistry as well as sediment characteristics of 25 springs were studied four times in 2003. The relationships between fauna composition and abiotic parameters were ascertained using multivariate statistical analyses. In total, fifty families or subfamilies and four higher taxa of invertebrates were identified in the springs studied. Only Gammarus fossarum (Amphipoda) occurred in all of the springs, whereas crenophilic taxonomic groups such as Turbellaria, Bythinellinae, Nemouridae, Limoniidae, Limnephilidae and Enchytraeidae as well as ubiquitous taxa such as Tubificidae and Chironomidae were very common but not present in all springs. Important factors determining differences in the taxonomic composition (at the family level) of the invertebrate fauna of springs were found to be those connected with their geographical location as well as chemical and discharge parameters, which were different for southern and northern groups of springs. The taxonomic richness, i.e. the number of invertebrate taxa, was found to be strongly dependent on discharge and the content of organic matter in bottom sediments, whereas specific taxa mentioned above had other abiotic determinants such as alkalinity, NO3 and temperature.
