The adaptation of soil microorganisms to different environmental conditions was investigated in the Austrian Central Alps (Hohe. Tauern). The floristic composition of the soil fungi at different sites was determined and the CO-release from soils taken from different altitudes was measured at different temperatures. The results showed a decreasing diversity of soil fungi with increasing altitude and a change in the dominating species at different altitudes and/or with vegetation patterns. The relative rates of CO-release from soils from different altitudes did not differ at different incubation temperatures. It was concluded that, among soil fungi the selection of species is a more effective mechanism for the adaption to changed environmental conditions than metabolic adaptations.
在奥地利中部阿尔卑斯山（陶恩山）对土壤微生物适应不同环境条件的情况进行了研究。测定了不同地点土壤真菌的植物区系组成，并在不同温度下测量了取自不同海拔高度土壤的二氧化碳释放量。结果表明，随着海拔升高，土壤真菌的多样性降低，且在不同海拔和/或植被模式下优势物种发生了变化。不同海拔高度土壤的二氧化碳相对释放速率在不同培养温度下没有差异。得出的结论是，在土壤真菌中，物种选择是比代谢适应更有效的适应环境条件变化的机制。
