| Tartalmi kivonat: | The authors studied the communities of fresh-water molluscs in Cri$/K6ros Rivers. According to the prelevance of the species and to the composition of the communities, they draw an inference concerning the condition of the water. The negative influence of pollution and of hydrotechnical works upon molluscs is very emphasized. The authors call attention to the importance of the relict mollusc fauna in the thermal springs of Cri$/K6ros Basin and they also underline the necessity of their protection. At some sites the unionids have a high diversity, but are indicated also cases of mortality. |
