Chironomiden und andere bodentiere der südschwedischen urgebirgsseen : Ein beitrag zur kenntnis der bodenfaunistischen charakterzüge schwedischer oligotropher seen
Problems. Methods. Material. There are more than 85000 lakes in Sweden, the majority of which belong to the oligotrophic type sensu Naumann, and which present an inexhaustible field for investigation. In view of the varied and complicated nature of the problems and the young age of limnological scie...
