| Abstract: | Faunistic Investigations of the Hyporheic Interstitial of the River Mur (Styria, Austria) Two distinct sections of the River Mur (Styria, Austria), one almost unpolluted and the other heavily polluted by domestic and industrial waste waters, were investigated for two years. Faunistic, hydrographic, and ecological investigations were carried out at the river bottom, including particularly the hyporheic interstitial zone. All species found were investigated qualitatively and quantitatively, and ecological factors are stressed. The composition of the fauna of the unpolluted area differs markedly from that in the polluted section. |
